Markos Giannopoulos22,837A circle of relevance and engagement // It's been a while since I've done a circle like this, I've been neglecting my duties! This is a thank you to people who have engaged with my recents posts, added me in an original circle of their own and also people which Google has ranked them to be of high relevance to my posts and my overall G+ tastes.  So, thank you for making my Google+ better! :) As always, this circle could not be created without +Circloscope and +CircleCount  #circlesunday   #circleshare   #circlediscovery   #engagers   #relevance  2014-11-02 13:08:16229252257

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 00:55:3849011616

Jack C Crawford67,189So you all might remember the Angels circle, right?This one has 440 cool guys (caveat emptor ... my preferences may differ from yours ... I like all of these gentlemen).So here's to the men!G+{I added myself just because ...}2013-07-10 20:10:59441913783
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 20:53:39100662467
Gideon Rosenblatt23,936My Top 150 Here are the 150 people that Google tells me are most relevant to me here on Google+. This is a really good group of people, full of interesting insights and a willingness to help others.I give you a hardy recommendation to add these folks to your circles here. Your stream will thank you for it later.:-)2013-02-22 00:43:3815037734
INTP0Since last time I shared the INTP circle, the followers circle grew from 66 to 192. So I'm sharing this circle again. If you do not want to be in the circle being shared, please let me know.This circle will be updated from time to time. If you'd like to be included in this circle, add INTP page. That way I can add you back. (A Google Plus page cannot add any user unless the user add the page first.)2012-11-17 09:56:49193202
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 00:32:2970317

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 07:52:4314619321

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. Until next week that is, when I've cooked up a fresh batch of algorithms. But that's then, and this is now, here, enjoy:2012-08-08 07:35:1012933626

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 14:47:31300101339

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 03:01:005132610
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 09:24:0950043238
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 23:58:0014220210
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 23:29:32100702348
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 18:22:494491159

SciTech #ScienceSunday Digest - 21/2015.
Permalink here: http://www.scitechdigest.net/2015/05/yeast-opiate-production-crispr-gmo.html

Yeast opiate production, CRISPR GMO killswitch, Optical computation, Continuous roll graphene, Cell periodic table, Immune evading implants, Wearable muscle sensor, Molecular pumps, Learning robots, Laser scanner. 

1. Engineered Yeast for Opiate Production
After a number of years of effort by multiple groups the final enzymatic synthetic step in the pathway for opiate production (morphine, etc) has been completed and it is now possible to create strains of yeast that produce opiate drugs as part of normal metabolism http://www.nature.com/news/drugs-regulate-home-brew-opiates-1.17563. With such a strain and basic fermentation skills morphine-producing yeast could be grown in a home-brew beer kit, but the original development was intended for cheaper, simpler, production of opiates. I disagree strongly with the alarmist commentary and propaganda around this, including this quote from the linked article “All told, decentralized and localized production would almost certainly reduce the cost and increase the availability of illegal opiates — substantially worsening a worldwide problem.” which I consider myopic; I believe this would substantially improve a worldwide problem. 

2. CRISPR-Based GMO Kill-Switch
CRISPR has now been employed in a novel way to trigger the removal and destruction of modified genes from genetically modified organisms and leaving the original genes intact http://www.theverge.com/2015/5/19/8625623/gmo-crispr-kill-switch-self-destructing-dna. It seems the system can kill the cells directly, inactivate or delete just the modified or introduced genes, or do both. Triggers for activating the system could include light levels, the presence or absence of a particular molecule - useful for controlling crops for example - and others. This seems to be similar in application to Terminator gene technology that was developed to limit the spread of GMO crops by preventing the growth of new seed, but in this case you would still get seed that could only be grow in desired areas. 

3. Optical Computing Developments
We had a trio of advances in optical computing this week. First, the smallest-ever silicon photonic beam-splitter has been demonstrated, designed by novel algorithms, measuring just 2.4 microns on a side, and promising faster on-chip communication and processing http://unews.utah.edu/news_releases/silicon-photonics/. IBM announces new CMOS integrated silicon nanophotonics technology and new chips designed to work alongside electrical chips while transferring data at 100 Gbps (full HD movie in 2 seconds), first application in high end servers and data centers http://www-03.ibm.com/press/us/en/pressrelease/46839.wss. Layers of 2D graphene and boron nitride allow controlled propagation of confined light pulses (within the layered sheets) when a voltage is applied to the graphene http://newsoffice.mit.edu/2015/tuning-light-waves-with-2-d-materials-0520. 

4. Continuous Roll Production of Graphene
A new continuous roll-to-roll production method for manufacturing large sheets of graphene and possibly other 2D materials https://newsoffice.mit.edu/2015/manufacture-continuous-rolls-graphene-0521. At a rate of 2.5cm per minute the sheets are uniform and high-quality single-layer graphene; faster rates, up to 20x, still produce coated sheets but these are lower-quality with defects. While the process doesn’t yet produce sheets equal to the best batch-processing methods, different applications will have different quality requirements. Further improvements should result in improved quality and production speed. In related news a new 60% - 70% graphene ink formulation allows 3D printing of robust structures that retain many of graphene’s useful properties and used these as custom tissue scaffolds seeded with stem cells http://www.mccormick.northwestern.edu/news/articles/2015/05/printing-3D-graphene-structures-for-tissue-engineering.html. 

5. Towards a Periodic Table of Cells
New microfluidics technology can efficiently isolate single cells from a sample for analysis and when combined with new technology for single cell genomic analysis via cataloguing the mRNA expression profile of single cells is leading to an explosion in data and new knowledeg about different cell types in different tissues http://www.technologyreview.com/news/537416/single-cells-analyzed-at-unprecedented-scale/. This has resulted in identifying cells never seen before and recent studies such as a survey of 466 individual brain cells as a step towards a full cellular brain atlas, and mapping thousands of cells from a mouse brain to identify 47 different types. This is inching towards a periodic table of cells and a complete cellular map for the human body and their functions. In related news microfluidic techniques can now squeeze (immune) cells and force the introduction of desired antigens into them in order to create better and more effective vaccines out of the patient’s own cells http://newsoffice.mit.edu/2015/cell-squeezing-device-vaccines-0522. 

6. Better Implants that Evade the Immune System
New studies indicate that the geometry of implanted devices significantly affects how the body and immune system will tolerate their presence http://newsoffice.mit.edu/2015/designing-better-medical-implants-0518. While the material is important their results suggest that larger, spherical devices are better able to maintain their function and avoid the buildup of scar tissue. 0.5mm spheres loaded with pancreatic islet cells to treat diabetic mice failed within a month, whereas 1.5mm spheres continued to function past six months. Similar performance improvement were observed in many materials and also in primates. This is a very interesting platform for introducing novel living biosensors and living drug factories into people. 

7. Wearable Muscle Sensors with MyoWare
A new muscle sensor designed to be temporarily stuck on to your skin above the muscle group that you want to use can be used to trigger commands in various electronic devices and is currently available via kickstarter http://www.coolwearable.com/myoware-muscle/. This is related to the Myo gesture control armband that I’ve been keen to try out and I’d be tempted to back the kickstarter myself if the device came with bluetooth and could interface with my phone. I’m looking forward to further miniaturisation that allows these sensors and their wireless transmitters to be implanted and to take higher resolution readings. 

8. Designing a New Molecular Pump
The first entirely artificial molecular pump has been designed in which molecules pump other molecules http://www.northwestern.edu/newscenter/stories/2015/05/nature-inspires-first-artificial-molecular-pump-.html. The pump works via simple chemical reactions, driving molecules step by step up higher energy states and away from a natural equilibrium. The basic architecture involves a ring-shaped molecule that moves along a molecular thread or chain, storing energy as it does so by moving multiple rings towards one end. An interesting research novelty for now the ultimate goal is to have these little molecular machines power nanoscale devices, muscles, and perhaps perform computational operations. 

9. Learning Robots & Machines with Complex Goals
New deep learning algorithms enable some robots to learn new tasks via trial and error without pre-programmed details about the environment http://newscenter.berkeley.edu/2015/05/21/deep-learning-robot-masters-skills-via-trial-and-error/. A variety of tasks were successfully tested including putting a hanger on a rack, assembling a toy, screwing a cap on a bottle, and others, with learning times averaging 10 minutes to 3 hours depending on the level of complexity. In related news a reinforcement learning approach has demonstrated game-playing software that is capable of creating a hierarchy of goals while working towards a delayed reward http://nextbigfuture.com/2015/05/keen-software-house-makes-ai-that-can.html. 

10. Non-Mechanical Laser Scanner
DARPA has demonstrated its SWEEPER technology for enabling drastically improved LIDAR applications http://www.darpa.mil/NewsEvents/Releases/2015/05/21.aspx. Unlike conventional LIDAR devices SWEEPER does not require mechanical components and instead exploits silicon-based on-chip optical phased array technology that can sweep a laser beam back and forth 100,000 times per second. This is expected to enable LIDAR systems that are drastically miniaturised and extremely low-cost. Given LIDAR systems in autonomous vehicles are one of the most expensive components in an autonomous vehicle the benefits for a diverse array of applications are immense. A future version of Project Tango could even have one of these devices.

SciTech #ScienceSunday Digest - 16/2015.
Permalink here: http://www.scitechdigest.net/2015/04/bigger-immune-responses-probabilistic.html 

Bigger immune responses, Probabilistic computer vision, Self-powered camera, Quantum bits in silicon, CRISPR controls epigenetics, Laser perovskites, Multi-cameras, Metamaterial energy harvesting, Lots of robots, Accessible cell therapies. 

1. Engineering a Broader Immune Response Against Cancer.
A new discovery allows a much broader immune response to be generated against different types of cancer than was previously possible http://newsoffice.mit.edu/2015/using-entire-immune-system-halts-tumor-growth-0414. This works by activating both the adaptive and the innate immune systems at the same time by conjugating interleukin 2 molecules to antibodies that target specific cancer cells. In tests tumours disappeared completely in up to 90% of mice and when tumour cells were reintroduced they were quickly destroyed by the immune system. 

2. Computer Vision with Probabilistic Programming.
New probabilistic programming techniques can in many cases produce effective code that accomplishes in 50 lines of code what normally takes many thousands of lines of code http://newsoffice.mit.edu/2015/better-probabilistic-programming-0413. This is a result of making machine learning applications easier to build - probabilistic programming was developed to quickly utilise machine learning techniques that have worked elsewhere. Example applications include taking 2D pictures of faces and accurately reproducing 3D models of those faces. 

3. A Self-Powered Camera.
A self-powered camera has been developed that, as the name implies, doesn’t require any power to function via a photodiode image sensor that also harvests light energy http://www.cs.columbia.edu/CAVE/projects/self_powered_camera/. This is essentially combining the functions of a solar panel and image sensor into one device that switches operation - capturing energy at one point in time in order to power the device to capture image information the next. Check out the videos - this camera can currently record an image per second. Imagine passive cameras saturating the environment that record events and never need to be recharged or connected to power. 

4. Electrical Control of Quantum Information in Silicon. 
Quantum information has been encoded in silicon using electrical pulses for the first time https://newsroom.unsw.edu.au/news/science-tech/breakthrough-opens-door-affordable-quantum-computers. This group has been working in the space for a while now and has steadily improved the technology; from the first single atom qubits in silicon to improved control to long qubit lifetimes and now to control via electric fields. Using existing silicon-based chip fabrication methods might just enable manufacturing quantum computers in future. 

5. Using CRISPR to Control Epigenetics.
CRISPR can now be used to directly target and modify epigenetic changes in the genome http://pratt.duke.edu/news/pulling-strings-our-genomic-puppetmasters. To accomplish this the Cas9 enzyme was modified to remove the DNA-cutting region, which was replaced with another enzyme for transferring acetyl groups to DNA. This allows precise targeting and control of specific gene promoters and enhancers to control gene activity; remember each cell contains the same genome, it’s just a matter of which genes are switched on or off that give rise to differences. For the first time promoters and enhancers can be probed and characterised in such an effective way. 

6. Perovskites Now Made into Lasers.
Perovskite compounds are one of the most exciting materials in solar photovoltaics at the moment, and the same properties that make them effective in this application apparently also make them promising for lasers http://spectrum.ieee.org/nanoclast/semiconductors/devices/perovskite-leads-to-100percent-efficient-nanowire-lasers. A simple method can make perovskite crystals that function as high-efficiency, ultra-small nanowire lasers. Under testing these lasers demonstrate some of the best performance criteria of any lasing material, including near 100% efficiency in which every photon that the material absorbs is used to produce a photon of laser light. 

7. NextGen Photography with Multi-Camera Modules.
A company called Light is launching new camera modules comprised of multiple lenses and image sensors that all fire simultaneously to produce images that are combined into a higher-resolution, higher-quality final image with adjustable focus http://www.technologyreview.com/news/536816/a-way-to-get-much-higher-resolution-selfies/. The first Light cameras are expected in smartphones by 2016, boasting a resolution of 52-megapixels, and along with other improvements hopefully squeeze the quality of an expensive DSLR camera into smaller, cheaper devices. This is like advanced space telescopes that combine images from multiple devices to produce much clearer images; I think it is a great idea. 

8. Metamaterial Energy Harvesting from Light.
New metamaterial designs have resulted in surfaces that are able to absorb 93% of incident electromagnetic waves they have been tuned to, which is significantly higher than classical antennas http://www.aip.org/publishing/journal-highlights/harvesting-energy-electromagnetic-waves & http://scitation.aip.org/content/aip/journal/apl/106/15/10.1063/1.4916232. In this case the light was from the 3 GHz spectrum, but the group hope to extend these capabilities with related designs into the infrared and ultimately visible spectrum. Applications for the current capability includes efficient wireless power transfer for devices and chips. 

9. Lots of Cool New Robots.
We had a whole bunch of new robots this week. First, an innovative robotic kitchen and cooking robot from Moley https://www.youtube.com/watch?v=NnUDhjG95jI. Second, in line with Baxter and others yet another collaborative dual-armed manufacturing robot called YuMi https://www.youtube.com/watch?t=115&v=2KfXY2SvlmQ - lots of competition in this space. Third, a nurse robot able to accurately insert needles into arm veins to inject drugs or take blood https://www.youtube.com/watch?v=IpdTeGPruFA. Four, a taste of things to come for the DARPA robotics trial https://www.youtube.com/watch?t=43&v=L4B5BhDoS9o. Five, solar-powered flying bird-robot https://www.youtube.com/watch?v=vo9lIkY74n0. 

10. Accessible Cell Therapies.
RepliCel Life Sciences bill themselves as a regenerative medicine company and are developing - and plan to sell - a couple of cell therapies including treatments for (i) chronic tendinosis to improve healing of tendons, and (ii) baldness to encourage and improve hair growth https://www.fightaging.org/archives/2015/04/the-low-hanging-fruit-of-cell-therapy-development.php. These areas are considered “low-hanging-fruit” and aim to provide / introduce cells into areas of the body that have become deficient in certain cell types, for example, isolating hair follicles as a cell source, massively amplifying these cells to large numbers, and reintroducing them to the patient via injection to the appropriate areas. In animals the approach caused hair to grow in places it normally doesn’t, or made hair thicker in places it does.

SciTech #ScienceSunday Digest - 15/2015.
Permalink here: http://www.scitechdigest.net/2015/04/artificial-kidney-membrane-nanoscale-3d.html

Artificial kidney membrane, tissue engineered gonads, nanotube computing, 3D imaging chip, Nanoscale 3D imaging, Simpler CRISPR, Maintaining youthful stem cells, Tactile manipulators, Acoustic cell isolation, Acoustic metamaterials. 

1. Living Artificial Kidney Membrane.
In a similar vein to recent efforts in microfluidics to develop “organs on a chip” artificial membranes can now be produced that are coated by a living monolayer of kidney cells http://phys.org/news/2015-04-kidney-membrane.html. The primary application the group is pursuing relates to kidney transplants and dialysis treatments by ultimately scaling the device up to achieve clinical relevance. One can imaging rolling layers of membranes with relevant cells into tubes to form an artificial kidney or other organ system - artificial organs and tissue engineering needn’t be limited to conventional biological architectures. I also like the idea of controlled cell membranes in general; they might be programmed to mass produce any biological product of interest. 

2. Tissue Engineering: Artificial Testicles.
In related tissue engineering news we had an interesting article this week about the ongoing development of artificial testicles capable of producing functional sperm http://www.vice.com/read/the-science-of-artificial-testicles. The current (complex) device is designed to mimic the complex inner structure of testicles and the primary applications in mind are for aiding men struggling with infertility for a range of reasons to have children via IVF. The key here is engineering the right environment to naturally stimulate stem cells - convincing them that they are part of a testicle - to divide and differentiate into sperm cells, to take tissue engineering to the point of creating a sperm-making machine. 

3. Carbon Nanotube Computing.
Circuits made of carbon nanotubes take another step closer to fruition with a simple, scalable method to remove metallic carbon nanotubes from arrays and leaving the desired semiconducting nanotubes behind to do work http://phys.org/news/2015-04-purify-arrays-single-walled-carbon-nanotubes.html. Making defined arrays of nanotubes into circuits can already be done but until now making these circuits functional by removing metallic carbon nanotubes has not been possible. In related news carbon nanotube and polymer composites, inherently disordered bulk materials, can nevertheless be trained to produce a desired electronic output (mimicking a particular electronic circuit) as part of a process of materials evolution http://phys.org/news/2015-04-single-walled-carbon-nanotube-composites-great.html; understanding how these structures form might be very useful http://munews.missouri.edu/news-releases/2015/0409-engineers-now-understand-how-complex-carbon-nanostructures-form/.   

4. Chip-Based 3D Imaging for Devices.
A new millimeter-scale silicon chip incorporates a nanophotonic coherent imager - in which each pixel is an independent interferometer able to measure both intensity and distance information - that works as part of a LIDAR system to generate 3D images of objects in realtime http://www.caltech.edu/news/new-camera-chip-provides-superfine-3-d-resolution-46425. These are just begging to be incorporated into smartphones, Kinect / Leap Motion devices, and autonomous vehicles to name a few; remember one of the major expenses on an autonomous vehicle is the LIDAR system - chips like this will slash these costs. I wonder if the chip might be used in a different set-up to emit rather than capture 3D images? 

5. Nanoscale Optical 3D Imaging.
In related 3D imaging news, but this time at the nanoscale, a new imaging technology combining cathodoluminescence and tomography allows the use of visible light to generate nanometer resolution three-dimensional images of nanoscale objects http://news.stanford.edu/news/2015/april/nano-3d-imaging-040715.html. The technique takes many 2D images at many angles and uses algorithms to stitch these together to generate and identify the 3D structure of the object. There is a nice embedded video overview of the process. This is a nice new imaging platform that I’d expect to see used in many fundamental research investigations over time; the team quote applications in producing optimised and more efficient LEDs and photovoltaic materials. 

6. Simpler Mini CRISPR.
As if CRISPR couldn’t get any easier. The CRISPR gene editing toolkit has been expanded with a new Cas9 enzyme that is encoded by a gene that is only 75% of the size of the conventional Cas9 gene http://www.nature.com/news/mini-enzyme-moves-gene-editing-closer-to-the-clinic-1.17234. This makes the overall genetic package require to be inserted into cells that much smaller and that much easier / more effective to insert. This is particularly important for gene therapy approaches in which you typically need to package genes into a small virus particle. In proof-of-concept experiments the team used the new technique to successfully transfect the livers of mice and get a test gene into 40% of liver cells in one go - a pretty good result for somatic cell genetic modification. 

7. Maintaining Youthful Stem Cell Activity with Age.
New experiments in mice show that removing just two factors known as TIMP1 and TIMP3 (Tissue Inhibitors of MetalloProteinases) was enough to maintain tissue (breast tissue in this demonstration) in a youthful state in aged mice https://www.fightaging.org/archives/2015/04/loss-of-timp1-and-timp3-maintains-youthful-stem-cell-activity-in-aging-mice.php. With age tissue loses its ability to develop and repair due to a decline in the stem cell population. Removal of TIMP1 & 3 led to an expansion in the pool of stem cells, the maintenance of consistently high levels, and their remaining functional throughout the life of the mice, and all without an increased predisposition to cancer (which was originally predicted). I wonder when we might see the results of, e.g., RNAi knock-down of TIMP1 & 3 in humans?

8. Sensitive Robot Manipulators.
A couple of interesting advances in robotic hands enabling more sensitive manipulations this week. First, engineering new robotic hands that are much more touch sensitive by using touch sensors interacting with myriad different materials to build a “language” of touch that both a computer and human can understand and interpret http://www.nsf.gov/news/special_reports/science_nation/robotictouch.jsp?WT.mc_id=USNSF_51, with the hope this results in prosthetics that provide a genuine human touch experience to amputees. Second, the use of shape-memory alloys (wires) as muscle fibers in lightweight robotic and prosthetic hands and limbs http://www.kurzweilai.net/an-artificial-hand-that-can-respond-sensitively-thanks-to-muscles-made-of-shape-memory-wires and leveraging useful properties such as the highest energy density of all known drive mechanisms. 

9. Isolating Circulating Tumour Cells with Sound.
Building on work first demonstrated last year a group has developed an even better (20 times faster) microfluidic cell sorting chip powered by two acoustic transducers that produce a standing wave along the microchannel http://newsoffice.mit.edu/2015/sound-waves-detect-rare-cancer-cells-0406. It turns out that cancer cells and normal cells respond differently to the sound gradient due differences in compressibility and other factors. In tests 83% of cancer cells were isolated samples with as few as 1 cancer cell per 100,000 and blood samples from real cancer patients were successfully analysed. The order-of-magnitude improvement from last year makes the device clinically relevant. 

10. Acoustic Metamaterials.
On the topic of acoustic technology there were two interesting acoustic metamaterial advances this week http://nextbigfuture.com/2015/04/new-industrial-bubble-wrap-material-and.html. First, a bubble metascreen comprised of a 4mm thick rubber film with embedded bubbles can dampen sound and especially reflected sonar signals by 10,000 times - 100 times better than thought possible. Second, another acoustic metamaterial dubbed a phononic crystal can, when coated onto an object, cause sound waves hitting that object to flow around its surface without being reflected.

What music do you hypnotize yourself with?

Recent Song Discoveries

Just a half dozen songs I've discovered relatively recently from artists I've never heard of before and really gotten into. As I've gotten older I've found it becomes quite difficult to discover new music to really get into and so, thinking others might be in the same boat I thought I'd share this little playlist.

As they say, there's no accounting for taste, and it might not be your thing but it'd be great if you could share a few recent (last six months or so) songs from relatively unknown groups that you've also gotten into. And which myself and others might too. 

For those that don't know, my favourite artist of all time is Maynard James Keenan and pretty much everything he turns his hand to. With Eminem in second place. But other than that my musical tastes are all over the place and include everything from Beethoven's Fur Elise through to Fear Factory's Replica. ___What music do you hypnotize yourself with?

“These bacteria are not agnostic to artificial sweeteners,” says computational biologist Eran Segal of the Weizmann Institute of Science in Rehovot, Israel, one of the two scientists leading the study. The investigators also found that the microbial populations that thrived on artificial sweeteners were the very same ones shown—by other researchers—to be particularly abundant in the guts of genetically obese mice."

Calories in do not equal calories out, ever, and the effects of calories vary depending on a number of factors, not least their role in nourishing, or not, our digestive symbionts.___

Blueberries show promise as treatment for post-traumatic stress disorder

Roughly 8 percent of people in the US suffer from post-traumatic stress disorder (PTSD). SSRIs, such as Zoloft and Paxil, are the only currently-approved therapy, but their effectiveness is marginal. Researchers have found that blueberries could be an effective treatment.

Number 4 is awesome

SciTech #ScienceSunday Digest - 14/2015.
Permalink here: http://www.scitechdigest.net/2015/04/bacterial-batteries-bacterial-digital.html

Bacterial batteries, Magnetic biosensors, Bacterial digital memory, 3D NAND chips, Magnetic BCI compass, DNA-protein lattice, Engineering chlorophylls, Machine vision advances, Brain function imaging, Molecular membrane transport. 

1. Bacterial Magnetic Batteries
Interesting new work on iron metabolising bacteria show that they use microscopic magnetite particles as a type of battery, loading and unloading electrons during the course of metabolism http://www.sciencedaily.com/releases/2015/03/150326151654.htm. The cycle was repeated many times with iron-oxidising bacteria removing electrons during the day and iron-reducing bacteria adding electrons during the night to recharge the particles. The group speculate whether such a system might be used for toxic environmental cleanup, and whether other (industrially useful) bacteria might be engineered to do the same. I wonder whether this system can be co-opted as an implantable bio-battery for various devices? 

2. Magnetic Biosensors
On the topic of intersecting biology and magnetism a new biosensor has been developed that comprises a cylinder of hydrogel sandwiched between two small magnets in a device measuring only two micrometers http://www.nist.gov/pml/electromagnetics/20150327_gem_biochemical_sensor.cfm. The hydrogel is chemically altered to be sensitive to the parameter you wish to measure; in this example the hydrogel contracted or expanded depending on the pH. The expansion and contraction alters the distance between the two magnetic disks and this produced a change in the magnetic profile that was able to be determined via NMR or MRI readouts from anywhere - even deep within - the body. Future work will explore a range of functionalised hydrogels that respond to different parameters as well as different magnetic disk materials that produce different magnetic profiles and so might be used simultaneously with other sensors. 

3. Bacterial Digital Memory
This recent synthetic biology development involved engineering bacteria to be able to record data of events by writing and later reading DNA http://onlinelibrary.wiley.com/doi/10.1002/cbic.201500061/abstract. Using a DNA recombinase enzyme to power this cellular memory system integrates single stranded DNA into the bacterial genome in response to external signals, which can be read at a later time to determine whether and how often those signals - such as light in this case - were present. The memory storage was reversible and is a significant improvement over previous efforts. What signals might be useful to record inside your own cells for later read-out? 

4. High Density 3D NAND Memory Moves into Production
Intel and Micron announced that they are moving their new 3D NAND memory chip architecture into production this year http://spectrum.ieee.org/tech-talk/computing/hardware/intel-and-micron-move-3d-nand-into-production. The architecture is based on a 32-layer design that should enable the equivalent of flash storage USB drives with 3.5 terabytes of storage or a standard 2.5 SSD with 10 terabytes of storage. I remember having a 4MB memory stick for on of my first digital cameras. Similar 3D chip efforts from Samsung, Toshiba, and SanDisk suggest that 3D memory chips are a reality and will soon be found in our devices. 

5. Brain Computer Interface Compass
Blind rats, which had a geomagnetic compass and microstimulator plugged into their brains via a brain-computer-interface, were able to incorporate this new location information and navigate a maze nearly as well as normal sighted rats http://www.eurekalert.org/pub_releases/2015-04/cp-wgc032615.php. The research team quoted that: this demonstrated that the mammalian brain is flexible even in adulthood--enough to adaptively incorporate a novel, never-experienced, non-inherent modality into the pre-existing information sources. In related news yet another brain computer interface allowed a man to control a prosthetic hand via thought http://www.uh.edu/news-events/stories/2015/March/0331BionicHand.php. 

6. DNA Self-Assembled Protein Lattice
Building on work for self-assembling nanoparticle lattices via complementary DNA binding the same group has demonstrated the ability to self-assemble protein lattices made out of one or two different proteins http://phys.org/news/2015-04-dna-protein-lattice.html. In the proof-of-concept study DNA was attached to two well-studied enzymes via click chemistry; with DNA radiating from their surfaces the enzymes maintained their normal structure and active enzymatic sites. When formed into a lattice the enzymes maintained their activity albeit with an expected reaction rate reduction due to the reactivity of the core of the lattice being dependent on molecular diffusion through the lattice. This is a pretty exciting platform for further development of new materials and applications.

7. Synthesising Molecules to Absorb any Solar Wavelength
One of the most thorough studies of chlorophyll molecules aimed at understanding from first principles how these structures absorb particular wavelengths of light has resulted in new capabilities in designing and synthesising new molecules able to absorb any desired visible wavelength http://phys.org/news/2015-04-scientists-molecules-absorb-sunlight-oranges.html. Give the group a compound found in a plant or bacterium and they can predict what wavelength it absorbs; tell the group you need a chlorophyll-like molecule able to absorb a specific wavelength and they can design and synthesise it for you. A next, but more complex step, would be to alter the synthetic enzymes in bacteria or plants to have them produce the modified pigments. 

8. Machine Vision Technology Moves into Ever-More Areas
Machine vision technology is being cast into an ever-wider net of applications and in just this week alone we had another three interesting examples. First, the adaptation of machine vision systems developed for autonomous driving to home security applications able to distinguish between your pet (for example) and an intruder http://spectrum.ieee.org/view-from-the-valley/consumer-electronics/gadgets/autonomous-vehicle-technologies-migrate-to-the-internet-of-things. Second, the adaptation of machine vision systems to identify key anatomical features to assist surgeons in the near term (and robotic surgeons in the long?) http://www.wired.com/2015/03/google-robot-surgery/. Finally, the power of machine vision in studying and classifying galaxies http://www.technologyreview.com/view/536411/how-machine-vision-is-reinventing-the-study-of-galaxies/. 

9. Rapid Imaging of Brain Function
A new photoacoustic microscopy method is able to detect and record blood flow, blood oxygenation, and oxygen metabolism inside living brains orders of magnitude faster than ever before https://news.wustl.edu/news/Pages/rapid-imaging-living-brain.aspx. Spatial resolution also gets a big boost; in the study a mouse brain was mapped blood vessel by blood vessel and the team believe in future the technique will allow analysis of individual cells and complement fMRI. In related brain news a wikipedia of sorts for neurons has been launched http://www.cmu.edu/news/stories/archives/2015/march/wikipedia-for-neurons.html. 

10. Molecular Membrane Transport
I like this approach to transporting water molecules across membranes using modular molecules termed “aquafoldamers” that form a regular helix through the membrane and creat a channel through which individual water molecules can flow through http://phys.org/news/2015-04-powered-proton-gradient-world-first-helical.html. This system is driven by a proton gradient that significantly lowers the pressure difference required to move water through the channels. While the team quote next generation water filtration and desalination membranes as applications I’m wondering whether the basic building blocks can be chemically altered to be selective for a range of small molecules and not just water.

3, 8, and 9 are interesting to me

SciTech #ScienceSunday Digest - 13/2015.
Permalink here: http://www.scitechdigest.net/2015/03/nanoparticles-stimulating-neurons.html

Nanoparticles stimulating neurons, Nanotubes stimulating neurons, Bioprocessing aptamer hydrogels, Controlling circadian rhythms, Making CRISPR better, DNA nanofabrication, Festo’s insect robots, Magnetic heat & sound, Nanolasers & photonic guides, Plasma shielding. 

1. Stimulating Neurons with Gold Nanoparticles.
A promising new technique for precisely stimulating neurons has been developed that involves coupling gold nanoparticles to other molecules that specifically bind to neuronal sodium channels without blocking them http://news.uchicago.edu/article/2015/03/12/new-technique-uses-light-take-genetics-out-optogenetics. When irradiated with light of a specific wavelength the gold nanoparticles heat up and this causes the channels to open up and initiate a signalling cascade; antibodies were also used to bind the particles to different neuronal channels. The particles also remained bound to the cell surface and the neurons didn’t suffer reduced signalling efficacy after prolonged and repeated artificial activation. Referred to as optogenetics without the genetics, future applications might include artificial vision restoration. A very flexible platform with different nanoparticles perhaps responding to different wavelengths of light and so potentially allowing simultaneous addressable signals; I wonder if they can signal output in a similar fashion too? Other nanoparticles sensitive to radio waves have also been shown to open up the blood brain barrier http://www.nouvelles.umontreal.ca/udem-news/news/20150325-nanorobotic-agents-open-the-blood-brain-barrier-offering-hope-for-new-brain-treatments.html. 

2. Carbon Nanotube Fibers Interface with the Brain.
In related neuronal stimulation news, carbon nanotube fibers have been developed that allow for intimate two-way brain stimulation and measurement and have proven superior to metal electrodes http://news.rice.edu/2015/03/25/carbon-nanotube-fibers-make-superior-links-to-brain-2/. The fibers measure one quarter the width of a human hair, terminate at a functional tip about the width of a neuron, and are made by wet-spinning millions of carbon nanotubes together. The strength and conductivity of the fibers are certainly attractive, but what convinced the group to pursue this avenue was their flexibility, softness, and biocompatibility. The plan is to develop the platform into deep-brain-stimulation applications at first before exploring other possibilities. 

3. Bioprocessing with Hydrogels and DNA Aptamers.
A new microfluidic system comprises flexible fins capped with DNA aptamers that are embedded in a hydrogel able to respond to different stimuli https://www.seas.harvard.edu/news/2015/03/catching-and-releasing-tiny-molecules. When a biological solution is run through the chip, the aptamers bind to the target molecule they were designed for, and when the stimulus is applied the hydrogel moves the aptamers into a different environment to release the molecules; thus specific molecules can be quickly sorted and separated from a complex solution. The proof-of-concept involved pulling the thrombin enzyme from a mixture of proteins. The hydrogel can be made sensitive to temperature, light, electric/magnetic fields, ionic gradients, etc while the aptamers can be specifically targeted and respond to pH, temperature, and salt. Seems like a nice, modular, and extensible technology with lots of applications. 

4. Controlling Circadian Rhythms and Improving Sleep Cycles.
A couple of interesting studies this week provided insights into the control of circadian rhythms in the brain and improving sleep, a summary of both can be found here http://www.kurzweilai.net/neuroscientists-identify-key-cell-type-in-the-brain-that-controls-body-clock. First, a key group of neurons were identified in the suprachiasmatic nucleus that produce a signalling neuropeptide called neuromedin S, which is both necessary and sufficient for the control of circadian rhythms in the animal; this provides an interesting target to hack. Second, the latest evidence for artificial light, particularly blue light, having a negative impact on our sleep and health has been demonstrated and makes a strong case for limiting the exposure of such light before sleep. 

5. Increasing CRISPR Efficiency Eightfold.
A new development of the CRISPR genetic engineering system results in the system being eight times more efficient at inducing genetic modifications in cells https://www.mdc-berlin.de/44343169/en/news/2015/20150325-mdc_researchers_greatly_increase_precision. The advance was made possible by introducing genetic elements that inhibit one of two methods of DNA strand repair, which are (i) homology-directed repair in which introduced genetic elements contain flanking DNA used as a template to splice the cut, and (ii) non-homologous end-joining in which free DNA ends are joined without a template and tiny deletions occur. Basically, the new system inhibits (ii) from occurring and so making it far more likely that (i) will work to incorporate your genetic change of interest. In tests up to 60% of all cells were modified in one go with the new system, something that holds promise for effective and widespread somatic cell engineering at some point. 

6. DNA Origami & DNA Modular 3D Building Units.
DNA origami and DNA as a programmable molecular building material took another important step forward this week with a new approach to joining and modular 3D DNA building units by snapping together complementary shapes http://www.tum.de/en/about-tum/news/press-releases/short/article/32303/. This group has been a powerhouse in pushing DNA origami technology over the years. The new work programs DNA to self-assemble into 3D building blocks that are precisely shaped to fit together by incorporating the short-range binding mechanism known as nucleobase stacking that can snap multiple blocks together; currently the platform allows three different binding mechanisms to be used. The team used this platform to build micrometer sized filaments and nanoscale machines with moving parts, including nanoscale actuators able to switch or cycle between states orders of magnitude more often and more stably than any prior DNA origami technology. 

7. Festo Robotics Continue to Impress.
Festo is an incredible innovative company that continually produces amazing robots that have previously included a kangaroo, seagull, dragonfly, air jellies, and others. This week it showed off its latest insectoid additions, cooperative ant robots with 3D printed bodies and electronics are able to operate autonomously or work together to achieve goals, and truly elegant butterfly robots that really have to be seen to be appreciated http://spectrum.ieee.org/automaton/robotics/industrial-robots/festo-bionic-ants-and-butterflies - be sure to check the videos. In related robotics news a new Amazon contest hopes to spur faster and more efficient robotics automation in warehouses http://www.technologyreview.com/news/536086/amazon-robot-contest-may-accelerate-warehouse-automation/. 

8. Controlling Heat and Sound with Magnets.
Vibrations through 3D materials, known as acoustic phonons that propagate both heat and sound, have been shown for the first time to possess magnetic properties that allow them to be manipulated with magnetism http://spectrum.ieee.org/nanoclast/semiconductors/materials/for-first-time-reseachers-demonstrate-heat-and-sound-are-magnetic. In one proof-of-concept the team demonstrated they could reduce the amount of heat flowing through a semiconductor by 12%. Using the technique heat and sound waves can be steered magnetically, which is an interesting result and a new phenomenon to manipulate. But the experimental setup was precise and it isn’t obvious how immediate applications might be developed. 

9. Nanolasers and Photonic Guides.
One of the most efficient, easy to build, and compatible nanolasers ever build has been fabricated out of a monolayer sheet of tungsten diselenide atop a standard optical cavity base that is hoped to enable the device to more easily integrate and speed-up modern electronics http://www.kurzweilai.net/a-nanolaser-and-a-bendable-light-material-promise-to-speed-up-microelectronic-devices. Also, mentioned in the same article in related news is the fabrication of a 3D printed spatially-variant photonic crystal able to bend light around tight 90 degree corners without the losses that would occur in conventional fibers and other materials; yet another enabling photonic feature able to benefit improvements in modern electronics. 

10. Dynamically Generated Plasma to Dampen Shockwaves.
Boeing has developed (or at least filed a patent on) a technology able to dynamically generate plasmas able to mitigate or prevent damage from shockwaves caused by nearby explosive blasts for example http://spectrum.ieee.org/tech-talk/aerospace/military/boeing-files-patent-for-electromagnetic-arc-generator-to-protect-against-explosive-shockwaves. The system detects an explosion nearby and calculates when and where-from the shockwave will arrive, then uses an electromagnetic arc generator (and a LOT of energy) to heat a specific region of air in the path of the shockwave into a plasma able to attenuate or absorb the shockwave. Patents don’t get granted without demonstrating enablement and I do wonder if we’ll get to see this system successfully demonstrated.

The Future Of Voice-Activated AI Sounds Awesome

Voice recognition gets freakishly good. It used to be that voice recognition always fell short of our expectations, but there have been some recent major technology breakthroughs that have cracked the code on speech recognition. In the past 18 months, commercial speech recognition technologies have seen a dramatic 30 percent improvement. To put that into perspective, that’s a bigger gain in performance than we’ve seen in the past 15 years combined. These improvements are in part being driven by deep learning approaches combined with massive data sets.

Today however,  due to the emergence of a small but growing number of cloud based APIs like MindMeld, it’s now possible for developers to build an intelligent voice interface for any app or website without requiring an advanced degree in natural language processing.

Here comes the age of the Sun

Solar Electricity will generate $5 trillion of cumulative revenue by 2035 and break into industrial markets per Deutsch Bank

Deutsch Bank expects solar electricity to become competitive with retail electricity in an increasing number of markets globally due to declining solar panel costs as well as improving financing and customer acquisition costs. Unsubsidized rooftop solar electricity costs between $0.08-$0.13/kWh, 30-40% below retail price of electricity in many markets globally. In markets heavily dependent on coal for electricity generation, the ratio of coal based wholesale electricity to solar electricity cost was 7:1 four years ago. This ratio is now less than 2:1 and could likely approach 1:1 over the next 12-18 months.

SciTech #ScienceSunday Digest - 12/2015.
Permalink here: http://www.scitechdigest.net/2015/03/consciousness-is-global-clip-3d.html

Consciousness is global, CLIP 3D printing, Neuromorphic optical computing, Silicon photonic switches, DNA molecular transport, Magnetised graphene, More drone advances, Robotic arms, Targeted nucleic acids, Nanoparticles click. 

1. Network Theory and Global Consciousness.
Recent brain imaging studies strongly suggest that consciousness, our rich conscious experience, is indeed a global rather than local phenomenon in the brain http://news.vanderbilt.edu/2015/03/213466/. Network or graph theory was used in this case to examine the links between various parts of the brain that were related to conscious awareness; in this case subjects reported when they were aware of a small disk flashed briefly on a screen while an fMRI scanner imaged the activity of their brains. The data suggested that the whole of the brain became more functionally connected following reports of awareness. This would also appear to provide experimental support for Tononi’s Integrate Information Theory of Consciousness. 

2. CLIP Optical 3D Printing Technology.
If you missed this one this week you were living under a rock - everyone was sharing and watching the amazing new 3D printing technology unveiled by Carbon3D this week http://3dprint.com/51566/carbon3d-clip-3d-printing. CLIP stands for Continuous Liquid Interface Production and involves the use of a projector to programmably solidify discrete regions of a UV-curable liquid resin as the growing part is pulled out of the resin bath. This is forming solid structures in three dimensions continuously, without a print-head, and is 25x to 100x faster than conventional approaches on the market. A potentially transformative technological evolution, only now emerging from stealth-mode after heavy venture backing. Oh, and it does 1 micron resolution too; be sure to watch the videos if you haven’t already. In related news commercial interests develop open-source algorithms for better 3D printing https://www.llnl.gov/news/america-makes-taps-lawrence-livermore-ge-develop-open-source-algorithms-3d-printing. 

3. Brain-Like Computing with Light.
Microofibers produced from chalcogenide glasses possess a range of optical properties that allow them to be used to replicate a range of equivalent neuron and brain functions and signal protocols http://www.southampton.ac.uk/mediacentre/news/2015/mar/15_45.shtml#.VQo1Qv4mmyc. These can be thought of as photonic neurons that might one day enabled neuromorphic hardware with ultrafast signal transmission speeds, higher bandwidth and lower power consumption than their biological and electronic counterparts. The paper concluded: “we implemented an optical axon in an amorphous metal-sulphide microfiber that enables photonic synapses to perform analogues of fundamental neurophysiological functions of the mammalian central nervous system.” 

4. Large-Scale Silicon Photonic Switches.
In related photonics news the largest-ever silicon photonic switch has been developed, which enables higher bandwidth and lower energy losses http://www.osa.org/en-us/about_osa/newsroom/news_releases/2015/largest-scale_silicon_photonic_switch_to_be_presen/. Previous photonic switches incorporated just 64 switching elements but the new design manages 2,500 and 10k should be feasible. Existing architectures would never be able to scale to this level due to optical losses, but the new architecture circumvents this problem by incorporating new MEMS switching element that can switch states 1,000 times faster than existing MEMS switches. Applications include computing, networking, data transmission and routing. 

5. Tethered DNA Origami for Molecular Transport.
Advancing on the work of DNA origami “walkers” to transport molecular cargo across a surface this latest work simplifies and accelerates the process by using a tethered DNA origami molecule that is free to swing around and facilitate rapid molecular transport across surfaces in conjunction with natural diffusions processes http://www.nanowerk.com/spotlight/spotid=39476.php. The concept here is to use partial compartmentalisation that is able to rectify and utilise brownian motion to advantage, and the embodiment was a 30nm atomically-precise DNA arm swinging a molecular cargo around on a 90nm x 60nm platform.  Future hurdles to overcome include interfacing with the outside world and other applications include structured DNA sensing and computing arrays. 

6. The Benefits of Magnetised Graphene.
A simple and robust method for magnetising graphene with hydrogen has been developed http://www.nrl.navy.mil/media/news-releases/2015/nrl-researchers-pattern-magnetic-graphine. The magnetism can be controlled by adding or limiting the amount of hydrogenation, and a commercial electron-beam process can then etch away hydrogen to produce precisely defined magnetic patterns on the graphene. Applications include magnetic data storage of course, but it will be quite a stretch to see if they can actually achieve the million-fold improvement over current hard drives that they claim as “possible”. Tightly packed magnetic graphene might also make for much more powerful permanent magnets and this would also be worth exploring. In related news graphene quantum dots get better http://spectrum.ieee.org/nanoclast/semiconductors/optoelectronics/new-production-twist-for-graphene-quantum-dots-opens-up-applications. 

7. More Drone Advancements.
A few of interesting drone developments this week. First, drones can now be used to build high-resolution 3D scans of landmarks and larger areas http://www.technologyreview.com/news/535596/high-resolution-3-d-scans-built-from-drone-photos/, and as drone traffic and capabilities increase this might lead to high resultion 3D maps of the entire planet. Second, a new hybrid gas-electric drone has 13 times the range of a battery electric drone http://nextbigfuture.com/2015/03/hybrid-gas-electric-drone-has-13-times.html, with a flight time of 2.5 hours and a range of 100 miles, which is pretty damn amazing when you think about it. Finally, leading on from last week’s cockroaches, other researchers are flying beetles via remote control http://www.gizmag.com/remote-control-giant-flower-beetles/36588/. 

8. Easy-to-Program Robotic Arms Take Another Step.
A couple of important robot arm advances this week. First, Universal Robotics launched its new UR3 robotic arm in three different sizes http://spectrum.ieee.org/automaton/robotics/industrial-robots/universal-robots-ur3-robotic-arm. This is an easy to program multi-articulated robotic arm for a wide range of repetitive tasks that is safe to work near humans. Rethink Robotics also followed up its previous Baxter robot by launching the new Sawyer Robot which is again an easy to program multi-articulated robotic arm (unlike Baxter’s two) that incorporates a range of improvements to make it smaller, faster, stronger, and more precise http://spectrum.ieee.org/automaton/robotics/industrial-robots/sawyer-rethink-robotics-new-robot. It’s great to see competition heating up in this area and ongoing technical improvements delivering ever-better robotic capabilities. 

9. Targeted Nucleic Acid Drugs.
Nanoparticles (of gold or lipid in this case) that are coated with 100+ strands of DNA of specific sequence have been termed “spherical nucleic acids” and recently demonstrated very effective immunomodulatory properties http://www.northwestern.edu/newscenter/stories/2015/03/spherical-nucleic-acids-set-stage-for-new-paradigm-in-drug-development.html. The DNA is designed to target different cell receptors and in the this “spherical” form proves to be one of the most simple, efficient, and potent immunomodulators to be developed, with significant promise against cancer and autoimmune disorders. And also this week we had specific microRNAs being used in tissue regeneration, effectively - and temporarily - boosting cell proliferation to take the place of damaged tissue http://www.uphs.upenn.edu/news/News_Releases/2015/03/morrisey/. 

10. Nanoparticulate Click Chemistry.
A tough choice for number ten this week, but I went with the deceptively simple and innocuous click chemistry technique developed for easily and controllably joining nanoparticles together and to other surfaces http://phys.org/news/2015-03-click-modern-chemistry-bonds-nanoparticles.html. Click-chemistries are usually used to precisely control the chemical connection of one molecule to another as part of a defined synthetic step, but in this work the concept was adapted to nanoparticles and allowing the quick and permanent bonding of nanoparticles together and to solid substrates. Think ordered arrays of different nanoparticles, even quantum dots, in defined patterns working to perform some function.

1. Editing Memories While Animals Sleep.
This week researchers demonstrated how to controllably modify certain memories stored in the brains of mice while they sleep http://spectrum.ieee.org/tech-talk/biomedical/bionics/how-to-insert-a-memory-into-the-brain-of-a-sleeping-mouse. They accomplished this by (i) implanting electrodes into the hippocampus of the mouse and measuring the electrical activity while the mouse explored a new environment, correlating particular patterns of activity with particular locations in the environment, and (ii) when the mouse slept and these particular patterns were again activated as part of sleep activity, the researchers stimulated another set of electrodes in another part of the brain responsible for reward and pleasure. This directly modified the memory and resulted in the mouse seeking out only those areas of the environment that were now associated with reward and pleasure. 

2. Senolytic Drugs for Clearing Senescent Cells.
Senescent cells that have stopped dividing accumulate with age and accelerate aging and healthspan in many animal models is enhanced by removing these cells. Two compounds - the cancer drug dasatinib and and natural compound quercetin - have been tested for this purpose in mice and resulted in a significant boost to healthspan http://www.scripps.edu/news/press/2015/20150309agingcell.html. The mice benefited from a range of benefits including improved cardiovascular function, better exercise endurance, reduced osteoporosis, lower frailty, and typically with just a single dose - and with the benefits lasting seven months. Very keen to see this tested in humans as soon as possible. 

3. Confirming the Existence of Nanobacteria.
For the first time the existence of nanobacteria has been conclusively proven with demonstration of nanobacteria isolation, imaging, and sequencing http://newscenter.lbl.gov/2015/02/27/ultra-small-bacteria/. These functional bacterial species, which probably rely on other organisms for nutrients to some extent, were isolated from groundwater and found to measure just 200nm or less across; 150 of these could fit inside an E. Coli bacterial cell, and over 100,000 or more might fit inside a human cell. I read this and think of 100,000 little DNA computers churning along in just one of my cells; incidentally the genomes of the nanobacteria measure about one million basepairs in length. Might be a nice little hardware template for engineering to perform other functions within our bodies, entering and exiting cells - also wonder what overlap there is to Craig Venter’s minimal cell? 

4. Improved Interfacing and Control of Cyborg Cockroach Robots.
The development of cyborg insects took another step this week with a new system that improves over the method of inserting electrodes into insect antennae http://rsif.royalsocietypublishing.org/content/12/105/20141363. The system still utilises a “backpack” containing communications, power, and computation, but now involves inserting electrodes far more intimately into the prothoracic ganglia of the prototype cockroaches, and allows remote operation and locomotion control. Limitations include line-of-sight operation but the group hopes to overcome this by incorporating additional sensors and on-board directional error-correction. 

5. 3D Printing Customised Small Molecules.
A new automated 3D printer is able to synthesise small molecules in a modular fashion - such devices are also known as chemputers or chemprinters http://www.hhmi.org/news/3d-printer-small-molecules-opens-access-customized-chemistry. As part of the proof-of-concept the team used a common set of chemical building blocks to controllably synthesise 14 distinct classes of small molecules. The work drew inspiration from cellular synthesis processes, and resulted in collection of hundreds of different, simple chemical building blocks that can be combined together repeatedly to produce more complex molecules; a company has been founded to commercialise. The promise is to one day have a chemical printer in your house able to synthesise any molecule on demand. In related news another new set of chemistries may expand these possibilities even further http://phys.org/news/2015-03-meta-technique-possibilities-molecular.html. 

6. Dynamic Imaging of Neurons with AFM.
A new long-tip atomic force microscopy technique has been developed for live-cell imaging at extremely high resolutions http://phys.org/news/2015-03-scientists-atomic-microscopy-imaging-nanoscale.html. The new device was used to produce images and movies of nanometer-scale morphological changes occurring in living cells, and showing structural changes in cells after exposure to insulin, as well as growing protrusions from hippocampal neuronal cells. Pretty mind-blowing stuff - movies of phenomena I never expected to be able to see. 

7. Stimulating the Brain with Magnetic Nanoparticles.
A new brain stimulation technique involves injecting iron oxide nanopaticles measuring 22 nm in diameter into the brain and then exposing specific regions to focused alternating magnetic fields http://newsoffice.mit.edu/2015/magnetic-brain-stimulation-0312. The applied magnetic field causes the nanoparticles to heat up, which quickly leads to activation of nearby neurons. This was a basic proof-of-concept study that originally emerged from cancer research that was using the nanoparticles to kill cancer cell in related regions; the nanoparticles can be heated to an amount sufficient to activate the neurons without harming them, and indeed have been used as MRI contrast enhancement agents for many years. A lot more work to be done however. 

8. Precise Forces on New Materials Produce Precise Colour Changes.
A new flexible materials reflects different wavelengths of light depending on how it is stretched and flexed http://www.osa.org/en-us/about_osa/newsroom/news_releases/2015/engineers_create_chameleon-like_artificial_%E2%80%98skin%E2%80%99/. Taking inspiration from how some insects are coloured via nanoscale structural features that reflect certain wavelengths of light, this new material is a thin layer of silicon etched with rows of ridges that has been embedded into a silicone film. The ridges only reflect certain wavelengths of light and by flexing the material the distance between the ridges changes, as does the wavelength of light reflected - with 83% efficiency and able to convert green light to red for example. Further developments should improve this and allow for some pretty interesting applications. 

9. Mimicking Carbon Structures with Silicon: Fullerane.
The two-dimensional silicon analogue of graphene - known as silicene - has been previously demonstrated and is a hot area of research. Now silicon analogues of other three-dimensional carbon molecules have been demonstrated http://spectrum.ieee.org/tech-talk/semiconductors/materials/carbon-buckyballs-have-a-new-silicon-rival. Christened “fullerane” this molecule is comprised of a lone chlorine ion inside a cage of 20 silicon atoms that are attached to and surrounded by a halo of 12 other silicon atoms that are linked to a trio of chlorine atoms. The interesting thing here is that the chlorine-silicons provide functionalisation sites that can allow linking of other molecules or indeed to joining the silicon cages together in two- and three-dimensional arrays.

10. Latest Farm in a Box.
The latest farm-in-a-box builds on other farm-in-a-shipping container projects to create a very attractive unit http://www.treehugger.com/lawn-garden/farm-box-produces-acres-worth-crops-shipping-container.html. The system uses 90% less water and 80% less fertiliser in a complete hydroponic growing and monitoring system that houses 2,800 growing spots in its 30 square meters, which might produce as much food as an entire acre of farmland. I’ve long been a fan of modular, automated food growing solutions such as this that, with the help of a few more technological iterations and cost reductions might really take off to enable more distributed, decentralised, and personal food production.

The Autopilot Tech That Could Be a Total Game-Changer for Drones

Autopiloting systems could make life easier for drone pilots. Even though most seasoned drone pilots have to spend much of their attention on avoiding hitting whatever they’re using a drone to examine — the beams supporting a bridge, or perhaps a tall building under construction, for example. Better autopiloting systems could help pilots focus more on doing their jobs. There are several other drone collision detection systems on the market, but Ascending CEO and co-founder Daniel Gurdan says the RealSense cameras set his company’s product apart. Smaller than other 3-D cameras, the RealSense camera module weighs only 8 grams and is less than 4mm thick.

Invictus

Out of the night that covers me,
      Black as the pit from pole to pole,
I thank whatever gods may be
      For my unconquerable soul.

In the fell clutch of circumstance
      I have not winced nor cried aloud.
Under the bludgeonings of chance
      My head is bloody, but unbowed.

Beyond this place of wrath and tears
      Looms but the Horror of the shade,
And yet the menace of the years
      Finds and shall find me unafraid.

It matters not how strait the gate,
      How charged with punishments the scroll,
I am the master of my fate,
      I am the captain of my soul.

Defying textbook science, study finds new role for proteins

Open any introductory biology textbook and one of the first things you'll learn is that our DNA spells out the instructions for making proteins, tiny machines that do much of the work in our body's cells. Results from a study published on Jan. 2 in Science defy textbook science, showing for the first time that the building blocks of a protein, called amino acids, can be assembled without blueprints -- DNA and an intermediate template called messenger RNA (mRNA). A team of researchers has observed a case in which another protein specifies which amino acids are added.
