Johnny Stork7,288Spirituality & Self Development CircleWe all strive towards various personal, professional and for many, spiritual goals in life. In our increasingly crowded and interconnected planet, we are often reminded of how each of out lives intersect and how each of us share many of the same values and needs. Many of these shared values and shared needs included the welfare of others, the welfare of the entire planet and the welfare of all living creatures.One way to think of what it means to be "spiritual" or concerned with "self" development is simply to be concerned with something, or someone, beyond yourself, beyond the personal. Holding a transpersonal world-view.The people in this circle share these values, these interests in developing personally, professionally and spiritually for the sake of all people as well as themselves. I am honoured to share this circle of humanitarian, compassionate, learned and transpersonally inclined friends. #transpersonalpsychology   #spirituality   #selfdevelopment   #positivepsychology  2014-02-05 00:55:3849011716CC G+

Gideon Rosenblatt28,713Gideon Rosenblatt's Top 100These are the folks Google tells me are my most relevant people (slightly modified to remove people who are relevant, but not active here on Google+).Looking through this list, I can tell you that these are great people full of interesting ideas and engagement. I'm not in the circle here, so I can objectively say that this group is a worthy addition to your circles. Enjoy this group of people - I know I do. They enrich my experience here. Without them, I probably wouldn't still be here today. P.S. - If you got a notification, that means you're in the circle. 2013-06-11 20:53:39100662467CC G+

Matthew J Price4,908Here it is again, my Accelerated Thinkers circle.  These futurists, authors, transhumanists, nerds, experts, pages, and all around thought leaders account for the vast majority of the good news I receive from G+.  Whatever I share that I didn't find in my RSS feed came from these ladies and gentlemen.If you followed nothing but these 70 people, you would have a pretty solid idea of what sort of craziness is coming down the pipe.I owe them a great debt for the thoughtfulness of their content curation and the added value of their voices. Thank you!I no longer spend any meaningful amount of time searching for new people to add to this circle.  If you know someone that belongs here please leave a comment nominating them (or yourself) or send me a message.  If you know someone with educated opinions about the future who posts future relevant thoughts and news the majority of the time, that's what this circle is about. #ScienceSunday   #Transhumanism   #Futurism   #AcceleratedChange  2012-10-22 00:32:2970317CC G+

John Kellden10,222Social Curation, part 6: Social Curators v3"...what watch? Ten watch. Such much?"Subterranean Homesick Blues:+Bradley HorowitzPearltrees:+Oliver StarrSocial curation - an evolving set of buckets:1. Social media - which to me boils down to getting your story, your brand straight in this new networked, participatory, two-way market.2. Social business - including a large part of the startup scene, and also things like hackerspaces, 3D-printing, large companies struggling to adopt a new more social culture...3. Social signal - the whole analysis/symthesis thing, where we'll help each other understand what is going on, whether deeper learning, social learning, peer learning, informal learning, a quiet pervasive revolution happening as we speak.4. Social practices - where we share success stories, business cases , hangouts and experiential stuff, assessing what works and what doesnt.5. Social innovation and transformation - the difficult, complex, slightly less accessible corner - how global and local intersect, design thinking, narrative, sensemaking, semiosis, patterns, culture, transitions. I wouldn't be at all surprised if you all would find the odd post from me here. :)Social cocreation is da shiznitMy intention here is to honour two principles - one, the cocreated nature of this circle, since it is all about social curation. Two, if at all possible, provide an as rich and diverse signal as possible, for the benefit of all other Google plussers in need of our various social curation insights.Social curation: how we shape our content and how it shapes us in returnThere is quite probably as many different takes on social curation as there are people in this circle, and then some.Whither Dunbar? - What size circles?Keeping this circle under two hundred people thereabouts, might be a good size for new google plussers should they want to derive benefit from the gathered collective intelligence from this bunch of social curators.2012-09-26 07:52:4314620522CC G+

John Kellden9,492Google+ : Top EngagersLa creme de la cremeFifty people are selected by +John Fanavans :I have no idea how many people follow me. At some point, you decide that you will become a broadcasting service, and engage primarily with a core group. It happens to everyone. When you do, I suggest you reach out to new people like I do from time to time. Just to ensure you dont stagnate. And run public hangouts, they are hard, but they are worth it.He is not your guru. What he is though, is someone having thrown every conceivable angle and the kitchen sink on people, figuring out who are the top engagers:https://plus.google.com/u/0/118328436599489401972/posts/A8QsWpXLnXBHeuristics For The Win Win WinI've added a whole bunch of people, applying my own super seekrit heuristics, towards turning this into what is probably the best circle ever, never to be surpassed.

Chris Robinson24,784General Science Circle- Final UpdateLast August I started this General Science Database (http://goo.gl/tp06X), which could be uploaded into Google+ using the import contacts feature. Over the last year, the database has morphed into a shared circle and more recently into +Science on Google+: A Public Database. Due to the increasing overlap with the +Science on Google+: A Public Database, this will be the last time that I will be updating and sharing this circle.If you are a scientist, science teacher, or science writer, please feel free to add your profile/page to the +Science on Google+: A Public Database by filling out this form (http://goo.gl/yEg7M) and circling +Science on Google+: A Public Database. 2012-07-25 14:47:31300101339CC G+

Matthew J Price0Here is my most carefully curated circle of Acceleration Aware individuals.  These 50 people (plus myself) are the most outspoken about the real hot topics in futurism like Genetics Nanotechnology and AI + Robotics, but also about the philosophy, politics, economics and spirituality of the future.I carefully considered everyone on this list, plus many more people who are arguably more important in the transhumanist community, but are not active enough on G+ to contribute meaningfully.  Also, people who had a large majority of posts that were political in nature were selected against.If you want to see where the future is headed, these 50 are a good place to start.  If you feel like you belong in this circle, say so below!2012-07-09 03:01:005132610CC G+
John Kellden7,662Here's a few people who are not too shabby.I will spend a week in Greece with wife and kids. Have promised not to bring laptop, and not cheat too much with the G+ mobile thing either. This means you will have to wander aimlessly through the Google Plus Ghosttown while I'm working my tan, enjoying food and wine and sploshing about in the pool. But have no fear, quality content and even higher quality conversation is just a few clicks away, even if you only add a few of the people in the below circle. You all behave now, and talk more in a week.2012-06-18 09:24:0950043238CC G+
Gregory Esau9,648My Community Intelligence CircleI use the term community here pretty broadly, in that my community, the global community, and G+ all blur together in ways that make boundaries somewhat meaningless. Therefor, this is my Community Intelligence circle. Reading and engaging with these people will raise your intel (so to speak) of the world around us, the world of Google Plus, maybe your world, and the dots that connect them. For the many people who have circled me over the last few months (and thank you!!), these are the people that raise my IQ and EQ.2012-05-31 23:58:0014220210CC G+
Gideon Rosenblatt13,462Highly Relevant CircleI've gotten a bit out of the habit of sharing circles lately, and so thought I'd share this group of people that Google thinks are most relevant to me (in other words, the first 100 I get when I click on "Your circles" and sort by "Relevance"). Looking at this group, I'd have to say that Google does a very good job. Not perfect. There are people who I feel I interact with a lot here who are not in this top 100 of "most relevant" according to the Google relevance algorithm. The only tweaks I made were to take out a small handful of folks who aren't all that active on G+, but had high relevance because they are Gmail contacts I email a lot. So that's it. Enjoy this group. It's a great group of people. Very interesting content. Some are big Google Plussers, some not so big, but all are relevant - at least to me - and if they aren't already, I hope they will soon be for you as well.2012-05-29 23:29:32100702348CC G+
Meilani MacDonald2,935Small Business circle 1 of 2Hello small business peeps! I'm a small biz person and naturally I want to connect with other small biz owners. I really feel we all have so much to share with each other and to learn from one another as we navigate this world called Google+ that provides us with so many great tools and resources to support our small biz efforts. I also think it's a good thing to support each other, and lift each other up as we work towards our goals. So I've been collecting small biz people and shared small biz & entrepreneurs circles, because those are the people I most want in my own circles, to follow, to connect with, and to support. I have 700+ small bizzes in my circle, so I've split it into two circles to share with you. This is #1 of the 2, and #2 is next. Let's hear it for small business!Btw, speaking of supporting small bizzes, I host a TGIF Biz Networking Hangout every Friday at 4pm pst, now a Hangout on Air. It is a chance to give yourself and your biz a little promo, and I feature special guests who are small biz owners and who have all kinds of good advice and info to share with other small biz owners. Please check my profile for more info or to watch last Friday's episode, where we talked about QR codes and great ideas for how to use them, and also talked about the value of keeping content fresh on your blogs and web sites, and when and why to blog, or not to blog. #smallbusiness #sharedcircles #entrepreneur +CircleCount +Shared Circles Shared a Circle with You +Shared a Circle with you2012-05-28 18:22:494491159CC G+

Rob Gordon22,157*Entrepreneurs, Self-Employed & Small Business OwnersUPDATED SHARED CIRCLE: Part 1 of 2: A through L (by last name).Link to Part (M-Z):         http://goo.gl/0Fcg1Link to Supplemental 1: http://goo.gl/AXXrWLink to Supplemental 2: http://goo.gl/TZKKeLike to Supplemental 3: http://goo.gl/3x6hINOTE:  This circle is no longer maintained in its present form but is still a good place to start if you are looking for entrepreneurs to follow and connect with here.  It has mostly been replace with a Google+ community of the same name that you can find at http://goo.gl/ejG9P**********************This is the most recent update to the popular "entrepreneurs" circle that posted a few months ago. As you can see, it has gotten bigger than 500 people so I have had to split it alphabetically into two parts. These two circles includes the self employed, small business owners, independent contractors, small startup companies and pretty much anyone trying to make it outside of the traditional economy.This is different from the other business circles of this type in that it doesn't include too many of the "celebrity entrepreneurs" and instead has mostly people with their own business or venture. There are more than 800 people here, but this has been reviewed extensively since it was last published -lots of fantastic new people have been added, and some have been dropped - mostly because they don't interact much. The end result is a circle of really awesome business people who actively interact with others here and have a small business or entreprenueral mindset.This is a really diverse group and includes entrepreneurs of all stripes - some have well established ventures and are wildly successful, others are just getting started and haven't made it yet. As can be expected, it is a little tech heavy, but represents most industries and many different types of business. There are even a handful of people here who have traditional jobs, but seem to have an interest in small business issues and always seem welcome to help entrepreneurial efforts. The people in these circles post all manner of things - not just business, but all are smart and interesting people so I recommend that you check this out.I do want to add the disclaimer that this is in no way "definitive" - there are millions of entrepreneurs on Google+ and this is just a tiny fraction of them - the ones I have curated. It seems that about two seconds after I publish this I always remember someone I should have included so just me know if you think you should be here. I republish this periodically and generally add everyone who comments on the post.As with all circles of this size I would use some discretion in adding this - either update your existing circle, pick and choose the ones you like or use these as a trial circles - whatever works for you. I'm not even sure Google will let you add all this many names at once so you may have to come back if you want to add all of them. The technology for this is not perfect, but I am trying to do my part to help build a highly interconnected community of entrepreneurs here on Google+.I hope you find the people in this circle interesting.RobReshares welcome and appreciatedIMPORTANT: You don't want to follow people based on where their last name fits in the alphabit do you?

Gregory Esau7,037My Thank You CirclePeople I want to Personally ThankI've come a long ways since I came here to Google Plus back in September, in this sometime crazy adventure of being part of a revolution of people to empower ourselves to create the world we want and need for a sustainable future, and to bring together the terrific type of people that can at the same time build the kinds of organizations we'll need for a sustainable future. It has been an extraordinary journey, that when i take these times to step back and breath, and to survey where we're all at in this journey, blows me away. It's unfolded in ways i could not have imagined six months ago.I am an ordinary person wanting to accomplish extraordinary things. Somehow a magic has happened, that has attracted these extraordinary people. My journey would be no where if not for these people, who in some way, have found ways to believe in me, have helped me, helped me grow, and helped in this amazing journey we share in this world of GooglePlus, and this future we think we can be part of shaping. The first two months of this year have shattered my expectations as to what really is possible with the right people. The next months of this year we're going to find ways to exceed those expectations again. We're going to create the kind of Smart Revolution that can reshape how we think of our role in the world, and the kind of Smart Organizations that reshapes the role of organizations in the world, and this tandem will be part of a cycle that will pull us towards a fantastic sustainable world. To close, thank you to all of you in this circle, and to all of you I've connected to in Google Plus who have been part of all this. Thank You2012-03-17 16:37:523824010CC G+

Thank you Weston A. Price. You've been unduly criticized for your published Vitamin C research findings. You're a hero. So many biochemical processes rely upon Ascorbic Acid for their property functioning... And do many diseases have their origins in a deficiency of this critical water-soluble nutrient.

Most interestingly to me at the moment is the mechanism whereby Vitamin C positively modulates GABA receptors on the brain to be more active... Thus reducing Dopamine levels on the brain and generally relaxing the emotional intensity of the thoughts so that thoughts are less frantic, anxious, worried, concerned, depressed, hyperactive, over thinking, obsessive, etc.

Biochemistry is paving the way towards radical life extension and the abatement of diseases of aging.

Three Galaxies over New Zealand
Image Credit & Copyright: Mike Mackinven

No, radio dishes cannot broadcast galaxies. Although they can detect them, the above image features a photogenic superposition during a dark night in New Zealand about two weeks ago. As pictured above, the central part of our Milky Way Galaxy is seen rising to the east on the image left and arching high overhead. Beneath the Galactic arc and just above the horizon are the two brightest satellite galaxies of our Milky Way, with the Small Magellanic Cloud to the left and the Large Magellanic Cloud on the right. The radio dish is the Warkworth Satellite Station located just north of Auckland.

"It is not that we have a short space of time, but that we waste much of it. Life is long enough, and it has been given in sufficiently generous measure to allow the accomplishment of the very greatest things if the whole of it is well invested. But when it is squandered in luxury and carelessness, when it is devoted to no good end, forced at last by the ultimate necessity we perceive that it has passed away before we were aware that it was passing. So it is—the life we receive is not short, but we make it so, nor do we have any lack of it, but are wasteful of it. Just as great and princely wealth is scattered in a moment when it comes into the hands of a bad owner, while wealth however limited, if it is entrusted to a good guardian, increases by use, so our life is amply long for him who orders it properly.

The quest for enlightenment takes many forms.

The role of lactate in boosting memory

Focusing their attention on the molecular mechanism, the scientists discovered that lactate provides more than just energy. It acts as a moderator of one type of glutamate receptor (NMDA receptors), the nervous system's primary neurotransmitter. This glutamate receptor is involved in the memorization process, and the research demonstrates that lactate gives them what amounts to a turbo-boost. "Glutamate lets you drive in first gear; with lactate, you can shift into fourth and travel at 100 km/h," says Magistretti.___The quest for enlightenment takes many forms.

#ScienceSunday #Science

SciTech #ScienceSunday Digest, 33/14.
Cancer avatars, peptide click-synthesis, inkjet biosensors, nano-meso-self-assembly, tattoos produce energy, thousand robot swarm, pulsed fields open brain barrier, cancer screening with blood, supercapacitors.

1. Your Own Surrogate Cancer Avatar.
In the latest step for personalised medicine, people can, for $12,000 purchase a cancer avatar service from Champions Oncology; (i) a biopsy from a patient’s tumour is implanted under the skin of mice, (ii) the tumours grow because the mice are immunodeficient, (iii) a battery of different cancer drugs and combination is administered to the different mice, (iv) the drug(s) that were most effective against the tumours is chose to be administered to the human patient http://www.technologyreview.com/news/529901/a-mouse-with-the-same-cancer-as-you/. The animals serve as a living personalised medicine test tube. Such a powerful approach should help to remove the guesswork and trial and error in choosing the right drug(s) to give to patients, and so provide the best treatment sooner. 

2. Reprogrammed Peptide Synthetase Incorporates Novel Click-Chemistry Amino Acids.
A non-ribosomal peptide synthetase has been engineered to allow it to incorporate non-natural amino acids capable of click-chemistries, and so creating a platform for the production of peptides and proteins that can quickly be connected to other component molecules via click-chemistry coupling reactions http://phys.org/news/2014-08-reprogramed-nonribosomal-peptide-synthetase-incorporates.html. The catalytic activity of the enzyme complex was not reduced by the changes. This basically means that the substances produced by such enzymes can now be equipped with a convenient reactive site for highly-specific and efficient chemical modification - I’m thinking along the lines of directed self-assembly. And speaking of click-chemistry, this week we had an even more fundamental advance with the development of just the second “perfect” click-reaction to allow general connectors for molecular building blocks http://phys.org/news/2014-08-chemists-uncover-powerful-click-chemistry.html. 

3. Inkjet Printed Biosensors.
It is now possible to use an inkjet printer to print flexible organic thin film transistors on various substrates and then subsequently functionalise the insulator component with specific antibodies in order to create a device able to accurately detect the presence of a protein or molecule of interest http://phys.org/news/2014-08-inkjet-printed-field-effect-transistor-label-free-biosensing.html. The proof-of-concept device was used to detect a model human protein and successfully demonstrated the ability of the platform to cheaply produce novel biosensors against a range of different molecular targets. 

4. Self-Assembly Over Multiple Length-Scales.
While the (paywalled) journal article is infinitely more informative than this press release http://www.umass.edu/newsoffice/article/eco-friendly-%E2%80%98pre-fab-nanoparticles%E2%80%99-could, what this group has done is develop a method for controlling molecular assembly over multiple length scales. This involves an initial step of molecular self-assembly in which defined free polymers and macromolecules separately formed nanoparticles of targeted & tunable sizes, and is followed by a second step of geometric packing of nanoparticles into mesoscale composite materials and devices, the properties of which depend on particle composition, size, and ratio. The proof-of-concept included the creation of photovoltaic surfaces that might lend themselves to future roll-to-roll wet phase manufacturing methods. This is an interesting platform for mesoscale self-assembly of defined materials and structures. Speaking of self-assembly we also saw magnetic nanocubes spontaneously forming well-defined helical fibers http://phys.org/news/2014-08-coax-nanocubes-helical.html. 

5. Electronic Tattoos Produce Energy from Sweat.
A new sensor in the form of a temporary stick-on tattoo contains enzymes that detect and strip electrons from lactate produced by the body and so produces a weak electrical current http://phys.org/news/2014-08-tattoo-biobatteries-power.html. An iteration of the sensor turned it into a battery that, measuring 6mm square, produces 4 microWatts - something that the group hopes to enhance further with additional development. Think passive power sources for miniature wearable devices and yet another option in the future tool set for powering implanted medical devices. 

6. One Thousand Tiny Robots Collectively Swarm into Desired Shapes.
The robotics team behind kilobots keep making progress every year and this week published a pretty amazing demonstration with 1,024 tiny kilobot robots, each individually following very simple rules, but able to collectively self-assemble large arbitrary shapes as desired http://spectrum.ieee.org/automaton/robotics/robotics-hardware/a-thousand-kilobots-self-assemble. Be sure to watch the video too: A Swarm of One Thousand Robots. As the article points out, when you have a swarm that size the failure or individual units doesn’t really matter. Future work will focus on working with larger swarms, perhaps smaller robots, and robot designs that can securely attach to form stable structures; a fascinating form of digital matter that gets exponentially more interesting the smaller the robots and the larger their number. Assembling 3D structures and moving large groups at once (not just individuals traversing the perimeter) would also be great to see. 

7. Pulsed Electric Fields Open Up the Blood-Brain Barrier.
A new study showed that generating pulsed electric fields in targeted regions of the brain via insertion of miniature needle electrodes causes the blood brain barrier to open up and so allow the passage of drugs and other molecules that otherwise wouldn’t be able to enter the brain http://www.worldscientific.com/page/pressroom/2014-08-08-02. The study demonstrated little to no damage to surrounding brain tissue, failed to induce uncontrolled muscle twitches, and consistently opened the BBB for a defined period of time. The group have spun out a company to help commercialise the technology. I’m wondering if they can take it a step further, like an enhanced tDCS application, and achieve the same without the need for needle insertion. 

8. Early Detection of Cancer via Blood Screening for DNA.
Turns out that many, if not most, cancers shed fragments of damaged DNA into blood and this increases the more advanced the cancer becomes. Some groups have used this fact to perform studies looking at the possibility of using standard DNA sequencing techniques to do routine, early tests of patients - for example those who do not yet have symptoms - to detect whether or not the person has developed the very earliest stages of cancer http://www.technologyreview.com/featuredstory/529911/spotting-cancer-in-a-vial-of-blood/. Some of these groups have been largely successful in these efforts with most but not all types and stages of cancer; further improvements and detection sensitivity would ideally be developed. But regardless, in the majority of cases where this worked it would most definitely save lives because early detection and intervention gives the best chance for patient survival. Some precancerous cells can take decades to develop into full-blown cancers and so the window to successfully intervene early can be quite large. 

9. Engineering Better Supercapacitors.
I try to set a high bar for any battery or storage coverage in this list due to a range of reasons but this week we had a couple of interesting supercapacitor developments. First, a new material comprising stacked graphene riddled with holes of defined size demonstrated increase energy density and allowing supercapacitors to reach energy densities comparable to or better than lead-acid batteries http://phys.org/news/2014-08-graphene-framework-bridges-gap-traditional.html. Second, using hemp-derived carbons as electrodes and an ionic liquid as electrolyte produces supercapacitors with better performance compared to existing graphene supercapacitors, although not as good as the holey graphene above http://www.kurzweilai.net/could-hemp-nanosheets-topple-graphene-for-better-supercapacitor-electrodes. 

10. Capturing Carbon with Copper Foams.
Fine copper foam structures have been demonstrated as effective catalysts for converting carbon dioxide into formic acid and propylene, both of which can more easily be used as chemical feedstocks to produce other chemicals http://phys.org/news/2014-08-copper-foam-carbon-dioxide-chemicals.html. There are strong suggestions that the precise architecture of the foam is critical for conversion parameters and future work will explore the relationship between modifying foam pore depth and diameter and the amount and type of compound created; ideally controlling the architecture will allow the production of specific and desired compounds.

This is one for the history books. Kids, this is when nanomedicine and nanoengineering really kicked off!

A camera that can record 4.4 trillion frames per second, allowing scientists to capture new images of some of nature's most fascinating and blink-and-you-miss-'em processes, from intense chemical reactions to plasma dynamics, has been invented. It records at 450 by 450 pixels. "It has already managed to record images of heat conduction, a process that can happen at one sixth the speed of light." 

"Most exciting perhaps, is that the STAMP cam is working on entirely new principles." The system works by using "an all-optical mapping of the target's time-varying spatial profile onto a burst stream of sequentially timed photographs with spatial and temporal dispersion," whatever that means.___This is one for the history books.

#ScienceSunday #Science

SciTech #ScienceSunday Digest, 32/14.
Brain imaging & augmentation, IBM brain chips, sound from surface vibration, batteryless WiFi communications, magnetic microfluidics, perovskite LEDs, treating neurodegeneration, printable chiplets, miniature NMR.

1. New Brain Imaging and Augmentation Studies.
Many thanks to +Mani Saint-Victor for directing me to this article discussing the repair and augmentation of inter-laminar microcircuits across the neocortex, and specifically the use of technologies for the recording and microstimulation of cortical microcircuits to build neuroprostheses for such repair or augmentation of cognitive function http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3832795/. Of course, such general approaches may benefit significantly from improved brain imaging techniques, such as this new non-invasive method involving IR lasers shone into the brain from outside the skull to stimulate modified carbon nanotubes injected into the animal’s blood in order to gain an unprecedented look at blood flow in the brain http://news.stanford.edu/news/2014/august/skull-blood-flow-080614.html. And such a specific approach may benefit significantly from the new ability to synthesise uniform and structurally pure carbon nanotubes using defined molecular seeds for example http://www.empa.ch/plugin/template/empa/3/149811/---/l=2. 

2. IBM’s Neurosynaptic Brain Chips take Next Step.
IBM announced the latest incarnation and demonstration of its neurosynaptic SyNapse chip with nearly five billion transistors powering one million “neurons” and 256 million synapses http://www.technologyreview.com/news/529691/ibm-chip-processes-data-similar-to-the-way-your-brain-does/. As an example demonstration a chip was tasked with recognising cars, people, and bicycles in video of an intersection; it did so 100 times faster and consumed 100,000 times less power than a laptop computer programed to do the same. The architecture is inspired by the structure of mammalian brains and artificial neurons communicate via “spikes” in a similar fashion. The chips themselves are scalable and the team wishes to connect thousands together into a novel supercomputer, although programming the chips remains a problem that they continue to work on. In related news IBM is trying to gear up its Watson supercomputer to assist with business meetings and executive decision making http://www.technologyreview.com/news/529606/a-room-where-executives-go-to-get-help-from-ibms-watson/.

3. Video Image Processing of Surfaces Can Extract Ambient Sounds.
In one of the more unexpected announcements for the week a new algorithm was demonstrated that is able to reconstruct an audio signal by analysing minute vibrations on the surfaces of objects captured in video footage http://newsoffice.mit.edu/2014/algorithm-recovers-speech-from-vibrations-0804. Captured sounds included intelligible speech from a distance of 15 feet through soundproof glass. Video framerate is key however, and needs to be higher than the frequency of the audio signal; many tests used a high-speed camera (2k - 6k fps) but other tests succeeded with a standard 60 fps digital camera due to how image data is captured by these sensors. The work builds on techniques for measuring a person’s heart rate via video feed for example.

4. Batteryless Sensors Communicate Via WiFi Backscatter.
Building on earlier work in which batteryless devices communicated with each other by harvesting ambient radio, TV, and wireless comms, the same group has now demonstrated a method of very-low-power WiFi-backscatter communications for such devices - powered just by ambient radio, TV, and WiFi - to connect to the Internet via WiFi http://www.washington.edu/news/2014/08/04/no-power-wi-fi-connectivity-could-fuel-internet-of-things-reality/. The ambient backscatter method works by the devices simply reflecting or not reflecting WiFi signals from a WiFi access point, which is detected by a reader device (e.g. phone) as discrete changes in signal strength. While proof-of-concept data rates were only 1 kilobit per second this could be a key enabling technology for aspects of the Internet of Things. WiFi is also being used to see through walls again http://www.theverge.com/2014/8/7/5979723/x-ray-vision-using-wi-fi-on-robots. 

5. Active Magnetic Microfluidic Chips.
A surface patterned with micro-scale ridges and impregnated with a ferrofluid (oil loaded with nanometer-scale magnetic particles) spontaneously forms a ferrofluid cloak around droplets of water or other particles added to the surface. Once formed such droplets can be precisely controlled and manipulated by an external magnetic field http://newsoffice.mit.edu/2014/surfaces-can-control-how-fluids-particles-move-0801. A nice piece of fluid dynamics but applications might include for example microfluidic chips that lack defined channels, but rather droplets can be moved around “virtual channels” at will and reacted together in whatever combination is needed.

6. Perovskite Now for Light Emission as well as Absorption.
Perovskite is becoming a hot item in materials research focused on developing better solar cells. It turns out that the same properties that lend perovskites their excellent light absorption properties can also be exploited for excellent light emission applications, as recently demonstrated in perovskite LEDs http://phys.org/news/2014-08-material-perovskite.html. Added benefits include cheap, simple, and scalable manufacture, and straight-forward tuning to emit light in a wide range of colours. Related news in solar cell applications include flexible perovskite (textile) fibers able to harvest light http://phys.org/news/2014-08-inexpensive-flexible-fiber-perovskite-solar.html, and a new solar cell stacking technique aiming to create cells with 50% energy efficiency http://www.technologyreview.com/news/529651/stacking-cells-could-make-solar-as-cheap-as-natural-gas/. 

7. Combating Neurodegeneration.
We had quite a few advances against neurodegeneration this week. First, neurons created from reprogrammed skin cells demonstrated complete and functional integration with mice brains http://www.alphagalileo.org/ViewItem.aspx?ItemId=144227&CultureCode=en. Second, a new test for neurodegeneration based on visual processing abilities http://www.eurekalert.org/pub_releases/2014-08/cp-dii073014.php. Third, investigations into how disruptions of the flow of cerebrospinal fluid through the brain can contribute to the development of Alzheimer’s and how we should try to restore this flow https://www.fightaging.org/archives/2014/08/considering-cerebrospinal-fluid-flow-disruption-as-a-contributing-cause-of-alzheimers-disease.php. Fourth, a newly designed peptide blocks the formation of, and helps to clear, misfolded proteins that contribute to amyloid buildup in Alzheimer’s and other diseases http://www.washington.edu/news/2014/07/28/new-protein-structure-could-help-treat-alzheimers-related-diseases/. Fifth, the successful demonstration of a new drug in reversing the effects of Alzheimer’s in mice http://news.yale.edu/2014/08/06/search-alzheimer-s-drug-major-step-forward. 

8. Printable Chiplets Still Being Developed.
A PARC group chops silicon wafers into 200 x 300 micrometer chiplets and mixes these into an ink, within which individual chiplets can be electrostatically guided to precise spots and subsequently picked and printed and connected with printed electronic inks http://www.technologyreview.com/photoessay/529761/micro-chiplets/. This builds on initial work the group announced last year, extending the vision to enable the fabrication of new computing devices made up of arrays of chiplets that individually might comprise processing, memory, LED, MEMS, and other functions - all printed as needed to create custom devices. After demonstrating the placement and wiring of four chiplets, and ultimately wanting to do the same with billions at a time, the group still has a way to go. 

9. NMR Chip Measuring Just 2mm.
A new nuclear magnetic resonance spectroscopy chip has been fabricated to a size measuring 2mm by 2mm, and is the smallest NMR system ever built http://spectrum.ieee.org/tech-talk/biomedical/devices/an-nmr-device-the-size-of-a-seed. NMR applications are extensive (http://en.wikipedia.org/wiki/Nuclear_magnetic_resonance#Applications) but having such a cheap and miniaturised chip could open the door to a range of mobile and consumer applications such as diagnostic testing and environmental monitoring to name just two. While the prototype still needs a fist-sized permanent magnet to take readings, the miniaturisation advance was made possible with computational compensation of temperature fluctuations that can alter the fields of small magnets. 

10. Bendable Acoustics and Sound Traps.
New acoustic engineering methods allow soundwaves to bend around objects and interfere to form acoustic bottles and traps in air http://spectrum.ieee.org/tech-talk/computing/hardware/bendable-sound-waves-can-skirt-objects-trap-particles. The method involves precisely adjusting the phase and amplitude of dozens of closely-spaced speakers; a linear array of 40 speakers allows shaping of sound in two dimensions, while a two-dimensional array of 100 speakers allows shaping of sound in three dimensions. As part of the demonstration a 3D acoustic bottle or trap was able to grab and move a hard plastic ball. Other applications could include improvements to ultrasound imaging by being able to bend around bones to view soft tissues, and smaller acoustic tweezers to manipulate cells and other small objects.

SciTech #ScienceSunday Digest, 31/14.
Automating Connectome Maps, Converting CO2 to Feedstocks, Nvidia Boosts VR, Spray-On Perovskite, Universal Cancer Test, More Self-Assembly, Better Superconductor Theory, Commercial Organs on Chips, Printing Variable Alloys, Remote Cryopreservation.

1. Generating Brain Connectomes Takes a Big Step Forward.
Connectomics, the generation of complete neuronal circuit diagrams, took a big step forward with the demonstration of an automated algorithmic technique that analyses electron microscope images of brain slices and not only generates the 3D neuronal maps and connection diagram, but also identifies the individual types of cells that form the circuit and the function of these neural systems https://medium.com/the-physics-arxiv-blog/connectomics-how-the-emerging-revolution-in-neural-wiring-diagrams-is-about-to-change-biology-2a267b576e99. Such work often involves a huge amount of human labour and such effective automation should result in significantly faster progress in this field. The system was successfully tested against existing connectomes including that of C. elegans and the mouse retina, and consistently produces classifications that match those produced by human anatomists. In future additional data should help with identifying additional cell types, figuring out how to scale to human connectomes, and in general sparking a revolution in the study of brain circuits both within and between brains. Thankfully there is recent work on computational techniques to handle the deluge of neuroscience data http://spectrum.ieee.org/tech-talk/biomedical/imaging/can-computing-keep-up-with-the-neuroscience-data-deluge. 

2. Capturing Carbon Dioxide and Converting it into Useful Feedstocks.
We had not one but three of these this week. First, organometallic uranium molecules were demonstrated as being able to catalyse the conversion of gaseous carbon dioxide into the organic molecule oxalate http://www.scientificamerican.com/article/depleted-uranium-could-turn-carbon-dioxide-into-valuable-chemicals/. Second, another process that used molybdenum disulfide and an ionic liquid is able to reduce carbon dioxide to syngas http://phys.org/news/2014-07-catalyst-carbon-dioxide-fuel.html. Third, nanoparticles comprised of copper and cerium oxide were demonstrated to work as a catalyst in converting carbon dioxide to methanol http://phys.org/news/2014-07-nanostructured-metal-oxide-catalyst-efficiently-co2.html. Three tiny steps towards a future of harvesting atmospheric carbon dioxide as a building material and reducing levels to pre-industrial times. 

3. Nvidia Boosts the Capabilities and Realism of VR Displays.
A new prototype virtual reality headset built by Nvidia involves stacking two LCD panels on top of each other as part of a cascaded display, and offset by a tiny amount to produce a display that quadruples the resolution http://www.technologyreview.com/news/529201/lcd-hacking-trick-could-make-virtual-reality-more-real/. The technology also provides up to double the framerate that each individual panel is capable of. Overall the technology would provide a significant boost to the immersive qualities of VR displays such as the Oculus Rift, with marked improvements to resolution, framerates, and field of view made possible. 

4. Perovskite gets the Spray-On Solar Cell Treatment.
Perovskite is one of the most promising materials to emerge in the development of solar cells in the last year or two, and the latest research indicates that it can now be applied to surfaces using a spray-painting process http://phys.org/news/2014-08-scientists-spray-on-solar-cells.html. Perovskite already offers benefits including low cost, high efficiency, and now an even cheaper manufacturing process that lends itself to significant scale-up and high-volumes. The prototypes achieve energy efficiencies of 11%, whereas bulk perovskite achieves 19%, and commercial silicon panels 25%; further work would aim to close and surpass this gap while still maintaining low costs. Adaptive solar optics are also looking to cut costs and boost efficiencies http://www.technologyreview.com/news/529476/adaptive-material-could-cut-the-cost-of-solar-in-half/. 

5. Novel Universal Blood Test for Cancer.
DNA in white blood cells exhibits varying damage when subjected to varying levels of UV light. There is also a lot of evidence that cancer stresses the immune system. Recent work shows that in patients with cancer, white blood cells are more easily damaged by UV light, and by measuring the amount of DNA damage in such cells it is possible to diagnose and quantify whether the person is healthy, pre-cancerous, or has cancer http://singularityhub.com/2014/08/01/promising-early-results-on-universal-blood-test-for-cancer/. A study demonstrated the accuracy of the test in patients suspected of having melanoma, colon, and lung cancer. Such results are very promising but are still early; the study included only 200 or so patients for example and additional trials and much larger patient samples (and cancer types) will be required to validate such a “universal” cancer test. 

6. More Examples of Novel Self Assembly.
We had a few novel examples of self assembly advances this week. First, the demonstration of bead-spring polymers facilitated by DNA origami and magnetic beads in which the defined DNA sequence can control the flexibility of the material http://phys.org/news/2014-07-bead-lieving-scientists-bead-spring-chains-tunable.html. Second, flexible linkers added to proteins allows the proteins to self-assemble together via click-chemistry with atomic precision; the POC used green fluorescent protein and turned it into a fibrous structural material http://phys.org/news/2014-07-chemists-nanofibers-unprecedented-method.html. Third, we had the use of cyanostars to create self-assembled crystals on surfaces http://phys.org/news/2014-07-chemists-bricks-and-mortar-molecular.html. 

7. New Superconductors: In Theory and Practice.
A convenient feedback loop between theory and experiment has allowed a team to develop a new and deeper understanding of certain types of unconventional superconductors, and revealing that magnetism and its directional dependence in the material is the key property http://news.uic.edu/physicists-unlock-nature-of-high-temperature-superconductivity. For the first time it is now possible to quantitatively predict the superconducting properties of these types of superconductors and this will hopefully allow the development of materials with ever-higher transition temperatures. In related news new yttrium-based high-temperature superconducting tapes have been created that can carry currents of 100,000 Amps, the highest in the world http://www.pddnet.com/news/2014/07/magnets-fusion-energy-revolutionary-new-manufacturing-method. 

8. Organs on Chips Go Commercial.
Last year I covered sophisticated organs-on-chip technology, in which engineered microfluidic chips are functionalised with channels lined with living cells and tissues that mimic the biochemistry and physiology of human organs. This week the technology was spun-out into a new company to accelerate commercial development and market penetration http://wyss.harvard.edu/viewpressrelease/161/. The technology has been further developed and now chips more accurately mimic organs, multiple chips linked together with a fluid that simulates blood now better replicate “human-body-on-a-chip” systems, and automated tools for controlling the chips allow better ease of use. This will help accelerate drug development and testing and would ideally be recognised by regulatory agencies and replace animal (and human) testing at some point. 

9. 3D Printing Variable Metals and Alloys.
A newly developed 3D printing process allows the printing of structures that transition from one metal or alloy to another http://www.jpl.nasa.gov/news/news.php?release=2014-247. This is a laser sintering process that can essentially change the metal powder being used on the fly in order to create variable gradient alloys. Applications include objects for example that need to possess different properties in different sections or ends, such as different melting temperatures, densities, stiffness, thermal expansion, and magnetic capabilities. A good example of yet another step in the increasing sophistication of 3D printing technology. 

10. Remote Cryopreservation Services.
For the first time Alcor has tested and deployed field cryoprotection services outside the United States http://www.alcor.org/blog/alcor-deploys-field-cryoprotection-fcp-technology-overseas-cases/. While further optimisation is required this new technology and service offering allows patients in remote locations (basically the rest of the world) to now able to access cryopreservation given sufficient notice and vastly improve their chances of a successful - and timely procedure without having first to travel to Alcor or the US directly.

SciTech #ScienceSunday Digest, 30/14.
Affecting cognitive decline, negative mass, printing complete boards, atmospheric waveguides, spinning nanorods, restoring insulin sensitivity, wave tractor beams, biomimicry for audio chips, solar passive cooling.

1. A (Reversible?) Mechanism for Age-Related Cognitive Decline.
Recent studies show that extracellular matrix proteins in the hippocampus of animals undergo robust and progressive upregulation over time, increasing with age and believed to directly contribute to cognitive decline by inhibiting synaptic plasticity and cell mobility https://www.fightaging.org/archives/2014/07/involvement-of-the-extracellular-matrix-in-age-related-memory-loss-in-mice.php. The studies were conducted in mice and so confirming the effect in human brains will be important. Given that only one group of four proteins of the extracellular matrix increased strongly, this may present a convenient target to down-regulate protein expression and restore cognitive function. Speaking of cognitive decline a non-invasive retinal imaging technique claims to detect changes indicating Alzheimer’s 15 to 20 years before clinical diagnosis http://www.cedars-sinai.edu/About-Us/News/News-Releases-2014/Study-of-Noninvasive-Retinal-Imaging-Device-Presented-at-Alzheimers-Conference.aspx. 

2. Proving Negative Mass can Exist in the Universe.
The consensus in cosmology has been that negative mass cannot exist in the Universe due to theoretical conflict with things like General Relativity. However, recent analysis and new solutions to General Relativity imply that negative mass could indeed exist in our Universe without conflicting existing theories https://medium.com/the-physics-arxiv-blog/cosmologists-prove-negative-mass-can-exist-in-our-universe-250a980320a7. Turns out that if negative mass exists it would create a plasma in space that would absorb gravity waves, and so providing a plausible answer for why gravity waves have never been detected despite increasingly sensitive instruments. Whether there is a threshold frequency above which gravity waves might propagate through such a plasma is an interesting avenue of inquiry that might provide an interesting means to test the theory. A minority of cosmologists postulate that antimatter has negative mass but there has not yet been an empirical test one way or the other http://en.wikipedia.org/wiki/Gravitational_interaction_of_antimatter. 

3. All-In-One Printer for Functional Circuit Boards.
Representing another little evolution in the technology for printable electronics, the Squink printer takes your designs for a circuit board, prints traces with conductive ink, prints conductive glue where the components will attach, and then finally engages a pick-n-place robotic tool to place the components - such as resistors, diodes, ICs, etc - where they are supposed to go http://gizmodo.com/this-all-in-one-printer-churns-out-completely-functiona-1608373786. Once the wet-phase material has cured and dried the printed board can be fired up and used; great little advance for hobby and prototyping applications with commensurate cost and time savings. Should get more sophisticated over time too.

4. Punching Laser Waveguides in Air.
Short, powerful laser pulses can now be used to create the equivalent of optical waveguides in air, the core of which has a higher refractive index than the outside, and so allowing concentrated focusing of subsequent laser light - avoiding the typical spreading and loss of intensity with distance that light in air experiences http://cmns.umd.edu/news-events/features/2356. The laser pulses last only a trillionth of a second, but the “fibers” or waveguides formed last for milliseconds; a very long time in comparison and longer than needed to take advantage of by firing more powerful beams down the guide with little or minimal loss of energy. While longer distances still need to be tested but there are very promising applications in high-bandwidth air-based communications, long-range chemical analysis, over-air power transmission, and laser weapons to name a few. 

5. Rapidly Spinning Nanorods for Chemistry and Medicine.
Nanorods injected into the bloodstream of mice and rapidly spun up by magnets have been shown to double the effectiveness of blood-clot busting drugs that help with stroke; the rods act like a mixing tool, shaking the clots and helping the drug be more effective and ideally allowing a much lower dose (and lower side effects) to achieve the same therapeutic result http://spectrum.ieee.org/nanoclast/biomedical/devices/nanoparticles-improve-stroke-treatment/. Further, nanorods measuring 300nm by 2000nm, placed in solution will rotate at 150,000 rpm when stimulated by 3MHz ultrasound, and act as a very effective and dispersed mixing mechanism with possible applications in speeding up chemical reactions http://phys.org/news/2014-07-ultrasonically-propelled-nanorods-dizzyingly-fast.html. 

6. Injecting a Single Protein Restores Insulin Sensitivity and Normal Glucose Metabolism.
Injecting the protein FGF1 (fibroblast growth factor) into mice with type 2 diabetes results in the restoration of normal insulin sensitivity and glucose metabolism for up to two days; sustained treatment could possibly cure type 2 diabetes in humans http://www.salk.edu/news/pressrelease_details.php?press_id=2037. The molecule does all of this without causing the normal side effects and other risks associated with most other diabetes drugs. While promising this is still early stage; to progress to humans the group wants to discover the biochemical pathway that causes the effect, and will also need to create modified proteins that stimulate insulin sensitivity without stimulating cell growth (which this one does).

7. Creating Tractor Beams with Waves.
It has previously been demonstrated that laser light can exert both a pushing and a pulling force on objects. Interestingly, these concepts have now been scaled up and applied to conventional water waves, in which the propagation and timing of water waves can either push or pull floating objects https://medium.com/the-physics-arxiv-blog/tractor-beam-created-using-water-waves-8d9271134c50. That’s a backward pulling force from forward propagating waves, and a pretty interesting fluid dynamics result. Applications could include feeding the knowledge back into the laser work for better optical tractors, better tracking of ocean-borne ships, rubbish, and debris, more efficient cleanup of oil spills, and fun applications with wave pools. 

8. Biomimicry Inspires Super Acoustic Chips.
Drawing on inspiration of a certain fly’s auditory apparatus - which it uses to precisely target crickets on which to birth its larvae - a chip-based replica has been engineered that uses a similarly-structured 3mm square mechanical beam on silicon with a piezoelectric coating that is able to very accurately sense displacement modes corresponding to sound direction and distance http://spectrum.ieee.org/tech-talk/at-work/test-and-measurement/mimicking-the-super-hearing-of-a-crickethunting-fly. Such a miniaturised chip-based acoustic sensor has military applications in sensing the direction and distance of sound sources, but it might also help improve this indoor positioning system based on echolocation http://www.technologyreview.com/view/529176/an-indoor-positioning-system-based-on-echolocation/, or even allow simple devices such as mesh networked sensors to cheaply and easily determine the direction and distance to other devices. 

9. Engineering Passive Cooling into Solar Cells.
As good as current solar panels have become they suffer significant losses in energy conversion efficiency when they become too hot and proposals to install active cooling systems almost defeat the point due to the energy required by the pumps. A new passive cooling system involves applying a thin layer with a pattern of micropyramids onto the panels that are optimised to draw away heat and shed it into the atmosphere as infrared radiation http://www.gizmag.com/self-cooling-solar-cells/33061/. The coating lets visible light in and and infrared light out, and should lower operational temperatures, increase efficiency, and lengthen operational lifetimes. 

10. Project Loon Matures After One Year.
Twelve months after first being announced Google’s Project Loon has started to mature, achieving new and significant milestones with its high-altitude balloons designed to provide wireless, ground-level Internet access http://www.wired.co.uk/news/archive/2014-06/17/google-loon-one-year-on. Now considered to be more likely than not to be a viable commercial operation in future, the balloons are providing up to ten times the bandwidth, navigational abilities, and flight times compared to one year ago. A year ago the balloons remained aloft for a few days; now an average of 75 days is common and many pass 100 days with some circling the globe three times. LTE communications have been added and download speeds reach up to 22 MB/s compared to 2 MB/s. One step closer to seamless global wireless Internet access.

Or if there is enough interest maybe we can think of some alternative funding models such as crowdsourcing shared interests and then crowdfunding (and co-researching!) the topic.

This is about general well-being but also increasing our understanding of Biology and health so that we can be more personally empowered and responsible for how we handle the stresses of daily life and aging. Nobody is perfectly healthy. Even if you don't have a disease and aren't sick, I guarantee you could be more fully engaged in life if you made a few carefully considered changes to the things you consistently do or put inside your body.

By paying for this service either individually or through crowdfunding, you would be helping me achieve my passion: to use scientific research to better mankind in practical ways so that individuals can more successfully do what they're good at... And make society better.

I believe that there are few things more virtuous than a collective group of people refining each other and helping each other.

If enough of the right kinds of people can do enough of the right things, we can form a network of people that can help sustain and accelerate the progress towards both personal and shared visions of ours.

There's so much scientific data available to us but it needs to be read and understood by the public or at least distilled into basic principles or actions which the data supports.

Be well all...I do sincerely hope this bears fruit.___

Thank you Weston A. Price. You've been unduly criticized for your published Vitamin C research findings. You're a hero. So many biochemical processes rely upon Ascorbic Acid for their property functioning... And do many diseases have their origins in a deficiency of this critical water-soluble nutrient.

Most interestingly to me at the moment is the mechanism whereby Vitamin C positively modulates GABA receptors on the brain to be more active... Thus reducing Dopamine levels on the brain and generally relaxing the emotional intensity of the thoughts so that thoughts are less frantic, anxious, worried, concerned, depressed, hyperactive, over thinking, obsessive, etc.

Biochemistry is paving the way towards radical life extension and the abatement of diseases of aging.

SciTech #ScienceSunday Digest, 28/14.
Non-invasive optogenetics, DNA origami antibiotics, smaller human genome, giant Lego blocks, self-assembly machines, implantable drug reservoirs, deep learning improvements, Clarity brain imaging.

1. Optogenetics Goes Non-Invasive With Red Light.
In a significant advance for optogenetics new opsin proteins have been engineered that are sensitive to red light, allowing a red light source external to the skull to trigger neurons and neural circuits that have been modified to express the new protein http://newsoffice.mit.edu/2014/noninvasive-brain-control-0629. In optogenetics studies of the brain a light source usually has to be inserted or implanted under the skull so that light can reach the modified neurons. Now with external light sources able to switch neurons on and off, applications in humans become much more feasible. The work also demonstrated partial vision restoration in mice by targeting diseased retinal cells. 

2. DNA Origami Delivers Better Antibiotics.
Tiny pyramid structures formed by self-assembling DNA origami strands have proven to be effective drug delivery vehicles against bacteria http://phys.org/news/2014-07-tiny-dna-pyramids-bacteria-easilyand.html. Gold nanoclusters attached to the corners of the pyramids allowed positional imaging to confirm cellular location, while the drug actinomycin was loaded onto the pyramid struts. The structures proved to be a more effective vehicle for delivering the drug into the bacterial cells, killing significantly more cells than the drug alone in proof-of-concept demonstrations. 

3. Human Genome Update to 19,000 Genes.
A recent study and analysis of the human genome as part of the ENCODE project presents an updated annotation comprising 19,000 protein-coding genes http://www.redorbit.com/news/science/1113185088/human-genome-reduced-to-19000-genes-070414/. Not only does this number seem to keep falling, but it seems that almost all of these genes have ancestors prior to the appearance of primates. A full 1,700 genes were cut from prior estimates due to the lack of counterparts in proteomic analysis. The number of new genes separating humans from mice is minimal and the differences between primates are overwhelmingly likely to be due to differences in gene regulation rather than differences in basic protein function.

4. Giant Lego Blocks for Home, Industrial, and Infrastructure Builds.
A company called Kite Bricks has launched the concept and prototypes for “Smart Bricks” made out of high strength concrete in a range of standard shapes that can be used to construct buildings rapidly and cheaply http://arstechnica.com/business/2014/07/these-bricks-are-like-lego-for-full-sized-buildings/. They possess a Lego-like nature that allows them to be easily connected and stacked together via slots, knobs, and voids on certain surfaces; a layer of double-sided adhesive is added where surfaces join. The design includes facilitation for structural steel components, insulation, and building infrastructure, and is expected to provide 30% energy savings and 50% lower construction costs. 

5. Prototype Self-Assembly Machines.
The first example of a self-assembly machine has been realised with a device capable of reel-to-reel, continuous-process fluidic self-assembly for fabrication of semiconductor chips (LEDs) over large areas for solid-state lighting applications and with yields greater than 99%, better than robotic pick-n-place operations http://www.nanowerk.com/spotlight/spotid=36474.php. This is an automated surface-tension directed process, with a 2.5cm wide ribbon able to assemble 15,000 chips per hour with multiple avenues available to explore full scale-up. The self-assembled LED panels were demonstrated as functional; I’d like to scale these up and wallpaper my house with them. Future work and improvements will allow self-assembly of more complex structures using different materials and shapes, but I’d really like to see DNA Origami and block copolymers added into the mix. I think this platform, or at least its evolutionary off-shots, will be transformative. More self-assembly advances this week, http://phys.org/news/2014-07-precision-functions-molecular-self-assembly.html. 

6. Implanted Remote Controlled Drug Reservoirs.
A company called MicroCHIPS has developed a 20 x 20 x 7mm implantable, wirelessly controlled chip + drug reservoir device whose delivery of a daily dose of drug can be switched on and off via smartphone for example http://spectrum.ieee.org/tech-talk/biomedical/devices/contraceptive-implant-hands-women-remote-control. Originally demonstrated with an osteoporosis drug in human clinical trials, the new development involves a contraceptive drug with enough daily 30 microgram doses to last 16 years (175mg total drug stored). A woman could implant the device and easily control her birth control regime over many years. What other drugs might this be used for? When might these devices use materials from the body to synthesise drugs in situ?

7. Machine Image Processing Now Matches Monkey Abilities.
New deep learning algorithms, under development for years, now match the image recognition abilities of monkeys http://www.wired.com/2014/07/cadieu. The experiments were conducted by measuring the signals from wires implanted into relevant regions of the monkey’s brains while they viewed a long series of test images; machines running the new algorithms had to identify the same series of images, and proved that they could match the performance of the monkeys. These algorithms have been advancing steadily and significantly lately and are on a trajectory to human-level abilities. In related news Numenta has launched algorithms that process information in a similar manner to the human brain (or Numenta’s model of it) for a number of different pattern recognition applications http://venturebeat.com/2014/07/09/numentas-brain-research-has-taken-a-long-nine-years-but-it-starting-to-pay-off-interview/. 

8. Clarity Brain Imaging Improvements. 
The CLARITY brain imaging technique, first announced last year, has been significantly improved http://med.stanford.edu/news/all-news/2014/07/seeing-the-inner-workings-of-the-brain-made-easier.html. Latest advances have successfully solved two early problems that plagued the technique, (i) removing fat from the brain without damaging the brain’s wiring, and (ii) allowing imaging of the whole transparent brain with common microscopy methods and without bleaching or otherwise damaging brain tissue with the technique. These advances promise to not only make the Clarity brain imaging technique much more widely accessible to people, but also allow much better studies to be conducted, and knowledge to be derived, from structural wiring features of the brain. 

9. Flexible Electronics and Soft Machines.
New nanoparticle inks allow simple and effective printing of electronics on flexible substrates http://phys.org/news/2014-07-cool-approach-flexible-electronics.html. The inks are intended to enable low-cost, simple fabrication methods to produce structures that perform better than conventional semiconductor materials. I wonder if such electronic inks might be used in implanted and tattooed electronic devices? Speaking of electronic inks and flexible substrates we also had new methods for fabricating soft machines and sensitive robotic skins http://www.purdue.edu/newsroom/releases/2014/Q2/new-manufacturing-methods-needed-for-soft-machines,-robots.html. 

10. Developing and Operating Artificial Cilia.
Cilia are typically cell-surface structures that bacteria switch back and forth to help them move around the environment; related structures help us move mucus and other particles along our throat. New surfaces have been created via self-assembly processes that are covered in artificial cilia molecules that switch in a similar manner when stimulated by light, thus allowing light-driven, light-controlled, directional movement of molecular-cilia surfaces http://phys.org/news/2014-07-artificial-cilia-scientists-nano-structured.html. This is another prototype approach to molecular fabrication plants with the cilia surfaces acting like conveyor belts able to move and position specific molecules at specific times and places.

SciTech #ScienceSunday Digest, 27/14.
Carbon nanotube applications, precise quantum dots, crossbar memory, 3D printed epoxies, GM probiotics vs obesity, cyborg robots, cell therapies, consciousness off switch.

1. Much Ado About Carbon Nanotubes.
A big week for carbon nanotubes, led by IBM’s announcement that commercial nanotube transistors are on the way with chips expected by 2020 http://www.technologyreview.com/news/528601/ibm-commercial-nanotube-transistors-are-coming-soon/. The company’s latest prototype chips pack 10,000 transistors made of carbon nanotubes and in 2020 should offer a five-fold improvement in performance compared to existing chips at the same power; mass-fabrication should entail only small changes to existing fab processes. Our control over nanotubes is becoming increasingly sophisticated, with it being possible to now induce accurate chirality-controlled growth of carbon nanotubes http://phys.org/news/2014-06-chirality-controlled-growth-single-walled-carbon-nanotubes.html, accurately control the 3D orientation of fabricated nanotubes http://www.nanowerk.com/spotlight/spotid=36288.php, and even assembling nanotubes into sensitve nanoscale force sensors http://phys.org/news/2014-06-scientists-sensor-carbon-nanotubes.html. 

2. Engineering Atomically Precise Quantum Dots.
Quantum dots can now be fabricated in certain circumstances with atomic precision http://phys.org/news/2014-06-quantum-dots-single-atom-precision.html. The quantum dots were fabricated with a scanning tunnelling microscope and are completely free of uncontrolled variations; by being identical their capacity to function as artificial atoms and display uniform characteristics is a breakthrough. But outside the realm of perhaps quantum computing real-world applications will require innovations in scale-up; possibly with STM chip arrays, possibly something else entirely. 

3. Commercial Fabrication of 3D Crossbar RRAM Memory.
Start-up company Crossbar has unveiled its first pre-production prototype crossbar resistive RAM memory arrays http://nextbigfuture.com/2014/07/crossbar-on-way-to-delivery-terabyte-on.html. Although the prototypes are only a 1MB demonstration but the potential is the replacement of the currently dominant NAND memory. Crossbar RRAM offers the possibility of terabyte data storage on a chip (postage stamp), 3D stacking, 20 times faster access speed, CMOS compatibility, and 10 times better lifetime / endurance of other memories. I remember when squeezing a gigabyte on a chip seemed amazing; seems doing the same with a terabyte isn’t that far away. 

4. 3D Printing Light, Strong Epoxy Cellular Composites.
Epoxy resins loaded with nanoclay platelets and either silicon carbide or carbon fibers have been used in 3D printing applications for the first time, depositing cellular composite materials that are incredibly light yet as stiff as wood or even concrete, and 20 times stiffer than current 3D printed polymers http://www.gizmag.com/3d-printed-strong-composite/32738/. The exact stiffness can be modified by simply changing the orientation of the fibers. The big attraction here is that it allows 3D printing for genuine structural applications - something not inherent in current 3D printed thermoplastics. 

5. Genetically Engineered Probiotics Versus Obesity.
It was only a matter of time. Genetically modified bacteria fed to mice prevent the animals from gaining as much weight as control mice http://www.popsci.com.au/gadgets/fitness/genetically-altered-bacteria-prevent-mice-from-getting-fat,388900. The modified bacteria produce a substance that is converted by the body into N-acylphosphatidylethanolamine, a hormone that travels to the brain and reduces appetite - the animals voluntarily ate less, gained less weight, and had lower insulin resistance. The bacteria survived in the gut for up to four weeks. Next step is to test in humans and so encourage a range of genetically engineered probiotics to be developed for human health. There is also evidence of microbes contributing to Alzheimer’s https://www.fightaging.org/archives/2014/07/microbial-contributions-to-alzheimers-disease.php and speciation http://www.simonsfoundation.org/quanta/20140604-evolving-with-a-little-help-from-our-friends/. 

6. Solar-Powered Conversion of Carbon Dioxide to Formic Acid.
An electrochemical cell, powered by a solar panel, was demonstrated to react carbon dioxide with water to produce formic acid http://phys.org/news/2014-07-solar-panels-carbon-dioxide-fuel.html. While the proof-of-concept achieved an efficiency of only 2%, the study showed that a simple system was able to take abundant water and carbon dioxide and use solar power to produce a more complex molecule useful in applications itself and also as a feedstock for producing more complex organic molecules. Not just carbon capture but distributed production of molecular feedstocks. 

7. Consciousness Off Switch.
A patient’s consciousness has been controllably switched off and on by electrically stimulating the claustrum region / structure in the brain http://www.newscientist.com/article/mg22329762.700-consciousness-onoff-switch-discovered-deep-in-brain.html. See more information on this region here http://en.wikipedia.org/wiki/Claustrum. The work seems to bear out theories claiming that the structure is required for rapid integration of information across different brain regions and binding information arriving at different times - which is believed to be necessary for consciousness. When consciousness was switched on again there was no memory of the event. Obviously, while intriguing and suggestive this needs to be replicated before being taken seriously. Less invasive means of targeting this region might also make for better and safer anaesthetic interventions. 

8. Another Option, Another Step for 3D Printed Transplantable Tissues.
An alternative technique for 3D printing artificial vascular networks for bioprinted organs has been developed http://www.sciencedaily.com/releases/2014/06/140630103136.htm. The method involves 3D printing interconnected fibers to serve as molds for artificial blood vessels, covering the fibers with a protein-rich gel loaded with cells that is solidified by applying light, and removing the fibers to leave behind the network of channels that are now coated in endothelial cells, which organise to form stable blood capillaries. Suitable, scalable vasculature is still one of the main factors holding back bioprinted organs. The promise of bioprinting and 3D printing in general becomes even more apparent when it seems that 3D printing might well be on a Moore’s Law-style 24-month doubling in performance, speed, and cost reduction http://3dprint.com/7543/3d-printing-moores-law/. 

9. Cell Therapies Becoming More Sophisticated.
We had a number of interesting cell therapy developments recently announced https://www.fightaging.org/archives/2014/07/a-selection-of-recent-progress-in-cell-biotechnology.php. These included (i) targeted isolation of corneal stem cells and subsequent exploitation to regrow anatomically-correct fully-functional human corneas in mice, (ii) the best demonstration yet for nuclear-transfer (to egg) stem cells being far superior to induced pluripotent stem cells for therapeutic applications; they are more completely reprogrammed and have gene expression and methylation profiles that more closely match embryonic stem cells, and (iii) engineering of red blood cells as potent drug delivery vehicles, toxin neutralisers, and sponges for particular molecules. 

10. Little Cyborg Robots.
Researchers have created simple, small “bio-bots” by fusing 3D printed hydrogel structures with strips of skeletal muscle cells, the activation of which can be controlled via electric pulses http://news.illinois.edu/news/14/0630biobots2_RashidBashir.html. The work builds on earlier studies that used heart muscle cells that pulsed continuously with little means to control the cyborg robot. The current design allows much better control for stopping, starting, and speed of movement in general. The group will next explore enhancements including (i) more complex structural designs to allow steering and additional means of control and (ii) incorporating neurons to see if movement and control can be influenced by light or chemical signals and possibly to react autonomously to sensed chemical cues.

SciTech #ScienceSunday Digest, 26/14.
Brain motor interfaces, verbally instructing robots, robotic hands, graphene fibers, untethered microgrippers, vacuum tube transistors, better nanopore sequencing, and others.

1. Brain Interfaces for Natural and Robotic Motor Control.
There were two promising advances this week in the area of brain interfaces allowing paralysed people to regain some motor control. First, after practising for a long time on a simulator that measured brain activity from an implanted brain chip a young paralysed man was able to naturally move his hand again for the first time in years http://www.washingtonpost.com/business/economy/science-fiction-come-true-moving-a-paralyzed-hand-with-the-power-of-thought/2014/06/23/13c9ac88-f8a1-11e3-a606-946fd632f9f1_story.html. Second, an in-depth look at the BrainGate program allowing paralysed people to control robotic arms - and perform quite complex tasks - just by thinking http://www.technologyreview.com/featuredstory/528141/the-thought-experiment/. The issues concerning (i) implants that become less sensitive with time, (ii) implants that risk infections, and (iii) systems that don’t provide sensory feedback all still need to be worked on. Other work also gleaned additional insights into how neuronal motor processing is accomplished http://www.cam.ac.uk/research/news/modelling-how-neurons-work-together. 

2. Robots Responding to Spoken Instructions.
New software and machine learning techniques allow a robot, in this case a PR2, to accept and act on spoken natural language instructions issued by a human http://spectrum.ieee.org/automaton/robotics/artificial-intelligence/robots-respond-to-natural-language-instructions. The proof-of-concept simply involves requests for different ice cream orders for which the robot diligently attempts to carry out successfully, most (64%) of the time. This is partly achieved by providing the robot with a grammatical or syntactical structure about its environment and objects in it, e.g. a pan is an object that can poured from or poured into and whose contents can be mixed or heated, etc. Simulation and crowd-sourced efforts are hoped to raise the success rate considerably. 

3. Stretchable Graphene Fibers and Yarns.
A simple and scalable fabrication method allows graphene oxide strips to be produced that can be wound together into a fiber that can be knotted and stretched without fracturing http://news.psu.edu/story/318882/2014/06/20/research/super-stretchable-yarn-made-graphene. The fibers and yarns are stronger than other carbon fibers, are impregnated with air pockets to prevent brittleness, and functionalised with other molecules to alter electrical conductivity. Made from graphite the material is quite economical too. In related news fabrication hurdles in producing extremely high-strength carbon nanotube fibers and yarns are being overcome http://nextbigfuture.com/2014/06/carbon-nanotube-fiber-ribbon-with-high.html. 

4. Untethered Single Cell Microgrippers.
I’ve previously covered arrays of single-cell microgrippers on a surface that can capture cells from solution. In this latest work the microgrippers are now untethered from a surface and can still capture and contain single cells http://www.nanowerk.com/spotlight/spotid=36211.php. Fabricated via photolithographic methods, up to 100 million grippers can be yielded from a single 12-inch wafer, with grippers fabricated with a range of sizes from 10 micrometers to 70 micrometers (when open). Future versions are expected to incorporate electrical and optical sensors to allow analysis of captured cells in vivo, and possibly be made from bioresorbable materials to allow dissolution clearance from the body. Lots of problems to solve such as sensor integration, yields, in vivo introduction and safety, and targeting, before these microbots evolve into fantastical nanobots. 

5. Resurrecting Vacuum Tube Transistors.
Described as a marriage between traditional vacuum tube technology and modern semiconductor fabrication techniques, prototype vacuum-channel transistors have been created that operate at 460 GHz and THz switching speeds are believed to be possible http://spectrum.ieee.org/semiconductors/devices/introducing-the-vacuum-transistor-a-device-made-of-nothing. The novel design at once seems to solve all of the problems that plagued old vacuum tube electronics while promising Moore’s Law-style miniaturisation, faster clock cycles, and greatly improved tolerance to both heat and external radiation. At the scale these transistors are made, even in an air or helium atmosphere, there is only ever a small chance that an electron will collide with a gas atom as it travels between source and drain; the transistors exploit a functional vacuum, if not an actual vacuum. 

6. New Type of DNA Nanopore Sequencing.
Using a genetically modified bacterial nanopore inserted into a membrane separating two salt solutions, a voltage can be applied across the membrane to make the salt ions in solution flow across the nanopore and create a measurable current. It turns out that when a strand of DNA is added to the solution and enters the pore, it impedes the current by an amount that depends on which nucleotide is inside the pore at that time http://phys.org/news/2014-06-nanopore-technique-rapidly-decodes-dna.html. The identity of nucleotides can be inferred by means of accurately measuring changes in current flow. Using a bacteriophage genome as a known DNA sequence the group has tested the system, confirming that it could reliably read all 4,500 base pairs of the sequence. Further research is needed to reliably sequence novel or unknown DNA sequences and the group has freely shared the knowledge in order to get more people involved. 

7. A Self-Powered Pacemaker.
A self-powered pacemaker has been developed out of a flexible piezoelectric generator http://www.sciencedaily.com/releases/2014/06/140623120316.htm. Simply bending and twisting the small flexible sheet was enough to generate sufficient voltage and current to stimulate a rats heart and should be enough to power a pacemaker without batteries, which have to be replaced every seven years in any case. Of course, such a device could also be used to power a wide range of other implantable medical devices, for example, BrainGate chips and related deep brain stimulation devices. 

8. More Links Between Fasting and Health.
There have been quite a few studies over the last year or two demonstrating the benefits of fasting for animals and people across a range of health areas. For both mice and humans in a Phase 1 clinical trial undergoing chemotherapy, those who fasted for between two to four days recovered quicker and suffered less collateral damage https://news.usc.edu/63669/fasting-triggers-stem-cell-regeneration-of-damaged-old-immune-system/; the fasting was actually found to clear the immune system of old damaged cells and stimulate stem cell regeneration of the immune system after the fasting ended. In another example, three days of fasting was shown to significantly improve survival of animals after kidney transplantation and renal injury https://www.fightaging.org/archives/2014/06/fasting-may-be-a-useful-addition-to-many-medical-procedures.php. 

9. Wolfram Programming Cloud Launched.
Stephen Wolfram has finally launched his Wolfram Programming Cloud, his latest and biggest attempt yet to redefine the process of programming and built on top of the Wolfram Programming Language http://blog.wolframalpha.com/2014/06/23/wolfram-programming-cloud-is-live/, much like Wolfram Alpha. Programs written in Wolfram can be given a web API in a very straightforward fashion and be deployed to the Cloud just as easily, making the program accessible anywhere. Arbitrary templates are available and APIs can be called from any standard language. Wolfram has billed this as enabling entirely new classes of software applications and for dramatically simplifying and automating many kinds of existing programming. 

10. Robot Hand Learns Grip for Any Object.
Shadow is a company that has developed a robotic hand that uses a Kinect depth sensor to assist in evaluating objects to be handled http://singularityhub.com/2014/06/25/robotic-hand-uses-ai-to-specialize-its-grip-for-any-object/. If the object has been seen before the system calls up instructions (memories?) for the best grip shape to use. If it is a new object it runs algorithms to guess the best grip to use and a failure results in this information being fed back into the process again. Integrated force sensors and tactile fingertips prevent the robotic hand from gripping a fragile object too strongly. The hand is designed to be modular and can be used on almost any robotics platform; many robotics companies have attached the hand to their robotics systems. Here’s an example video: Shadow Hand manipulates pen

Quick, get a drink and some popcorn! In less than an hour, at 4:30 UTC, you can watch the ESO blow up a Chilean mountaintop to make room for the E-ELT, the extremely large telescope.

The telescope's "eye" will be 39.3 meters in diameter and will gather 15 times more light than the largest optical telescopes operating at the time of its development.

The E-ELT will search for extrasolar planets — planets orbiting other stars. This will include not only the discovery of planets down to Earth-like masses through indirect measurements of the wobbling motion of stars perturbed by the planets that orbit them, but also the direct imaging of larger planets and possibly even the characterisation of their atmospheres.

Furthermore, the E-ELT's suite of instruments will allow astronomers to probe the earliest stages of the formation of planetary systems and to detect water and organic molecules in protoplanetary discs around stars in the making. 

The E-ELT will also be making detailed studies of the first galaxies and to follow their evolution through cosmic time. Observations of these early galaxies with the E-ELT will give clues that will help understand how these objects form and evolve.

Poem by: C. P. Cavafy

When you set out for distant Ithaca,
fervently wish your journey may be long, —
full of adventures and with much to learn.
Of the Laestrygones and the Cyclopes,
of the angry god Poseidon, have no fear:
these you shall not encounter, if your thought
remains at all times lofty, — if select
emotion touches you in body and spirit.
Not the Laestrygones, not the Cyclopes,
nor yet the fierce Poseidon, shall you meet,
unless you carry them within your soul, —
unless your soul should raise them to confront you.

Poem by: C. P. Cavafy

When you set out for distant Ithaca,
fervently wish your journey may be long, —
full of adventures and with much to learn.
Of the Laestrygones and the Cyclopes,
of the angry god Poseidon, have no fear:
these you shall not encounter, if your thought
remains at all times lofty, — if select
emotion touches you in body and spirit.
Not the Laestrygones, not the Cyclopes,
nor yet the fierce Poseidon, shall you meet,
unless you carry them within your soul, —
unless your soul should raise them to confront you.
 
Fervently wish your journey may be long.
May they be numerous — the summer mornings
when, *pleased and joyous, you will be anchoring
in harbours you have never seen before.*
Stay at the populous Phoenician marts,
and make provision of good merchandise;
coral and mother of pearl; and ebony
and amber; and voluptuous perfumes
of every kind, in lavish quantity.
Sojourn in many a city of the Nile,
and from the learned learn and learn amain.
 
*At every stage bear Ithaca in mind.
The arrival there is your appointed lot.*
But hurry not the voyage in the least:
’twere better if you travelled many years
and reached your island home in your old age,
being rich in riches gathered on the way,
and not expecting more from Ithaca.
 
Ithaca gave you the delightful voyage:
without her you would never have set out:
and she has nothing else to give you now.
 
And though you should find her wanting, *Ithaca
will not surprise you; for you will arrive
wise and experienced, having long since perceived
the unapparent sense in Ithacas.*___

Transmission of information via proteins could revolutionize drug discovery

The existence of information highways that connect and correlate distant sites within a single protein have been discovered by researchers. Their article furthers a key theoretical field for drug discovery, as it would allow the discovery of many more drug binding sites in proteins of biomedical interest.

Three Galaxies over New Zealand

No, radio dishes cannot broadcast galaxies. Although they can detect them, the above image features a photogenic superposition during a dark night in New Zealand about two weeks ago. As pictured above, the central part of our Milky Way Galaxy is seen rising to the east on the image left and arching high overhead. Beneath the Galactic arc and just above the horizon are the two brightest satellite galaxies of our Milky Way, with the Small Magellanic Cloud to the left and the Large Magellanic Cloud on the right. The radio dish is the Warkworth Satellite Station located just north of Auckland.___Clever

Science at work!

"The astronomers who this spring announced that they had evidence of primordial gravitational waves jumped the gun because they did not take into proper account a confounding effect of galactic dust, two new analyses suggest. Although further observations may yet find the signal to emerge from the noise, independent experts now say they no longer believe that the original data constituted significant evidence."

The practice of focusing on the totality of a thing, while pausing to consider the thing's possibilities through a behaviorist perspective... Often while doing the act. It is perceived by some intellectuals as a way to imbue specific and unique purpose into mechanistic actions/behaviors.

Nutrition is the phrenology of our time ? "The 600,000 articles — along with several tens of thousands of diet books — are the noise generated by a dysfunctional research establishment. Because the nutrition research community has failed to establish reliable, unambiguous knowledge about the environmental triggers of obesity and diabetes, it has opened the door to a diversity of opinions on the subject, of hypotheses about cause, cure and prevention, many of which cannot be refuted by the existing evidence. Everyone has a theory. The evidence doesn’t exist to say unequivocally who’s wrong."
