#Quote by Albert Einstein:
The Nuanced, Complex Religious Views of Albert Einstein:

“The finest emotion of which we are capable is the mystic emotion. Herein lies the germ of all art and all true science. Anyone to whom this feeling is alien, who is no longer capable of wonderment and lives in a state of fear is a dead man. To know that what is impenetrable for us really exists and manifests itself as the highest wisdom and the most radiant beauty, whose gross forms alone are intelligible to our poor faculties – this knowledge, this feeling … that is the core of the true religious sentiment. In this sense, and in this sense alone, I rank myself among profoundly religious men.”

The Nuanced, Complex Religious Views of Albert Einstein

Stephen Jay Gould has done us the favor of compiling a rich set of quotes to try to capture the complex, nuanced relationship that Albert Einstein had to God and religion. 

I will highlight this quote, but there are many others that are just as interesting:

“The finest emotion of which we are capable is the mystic emotion. Herein lies the germ of all art and all true science. Anyone to whom this feeling is alien, who is no longer capable of wonderment and lives in a state of fear is a dead man. To know that what is impenetrable for us really exists and manifests itself as the highest wisdom and the most radiant beauty, whose gross forms alone are intelligible to our poor faculties – this knowledge, this feeling … that is the core of the true religious sentiment. In this sense, and in this sense alone, I rank myself among profoundly religious men.”

#DriverlessCars

U.S. Government Classifies 'Driverless Car' Systems As 'Drivers'

Google and other companies working on the development of driverless (or 'autonomous') motor vehicles have scored a big symbolic victory, as the National Highway Transportation Safety Administration of the U.S. Government has ruled that self-driving systems can be classified as 'drivers', thus potentially opening the door to mass production of such technology for consumers.

This should also help inform states making their decisions about approving driverless vehicle technology going forward, such as California where recently they ruled (contrary to the NHTSA ruling) that driverless cars needed to include a seat with standard position and controls for a human driver.

Google and other companies have argued that requiring such seats and controls would actually make the vehicle less safe, as human drivers could override the driverless control system at inopportune moments. Statistics to-date would seem to confirm that, more often than not, the driverless system will make safer decisions on the road than human drivers do.

While this ruling doesn't address all of these issues as yet, it does argue against restricting the definition of a driver to a human occupant and against requiring vehicles to accommodate human drivers.

SciTech #ScienceSunday Digest - 06/2016.
Permalink here: http://www.scitechdigest.net/2016/02/better-gene-delivery-better-dna.html 

Better gene delivery, Better DNA aptamers, Light effect transistor, Rejuvenation advances, Atomically precise materials, Integrated photonics modem, Electronic nematicity, Deep learning chips, Graphene lenses & electrodes, Flexiramic materials. 

1. Delivering Genes Across the Blood Brain Barrier
Using high-throughput screening techniques combined with methods of directed evolution, researchers screened millions of viral variants to create a novel, modified adeno-associated virus that is able to efficiently get past the blood-brain-barrier and deliver genes and genetic engineering tools to neurons and other cells of the brain http://www.caltech.edu/news/delivering-genes-across-blood-brain-barrier-49679. This obviates the need to drill a hole through the skull to inject these vectors and provides a far more elegant tool that can be used for CRISPR-powered modifications. In related news rats have been cured of a genetic liver disorder with a more effective CRISPR-delivery system involving a different adeno-associated virus carrying guide RNA and repaired-gene-insert and lipid nanoparticles carrying Cas9 mRNA instructions http://news.mit.edu/2016/crispr-curing-disease-repairing-faulty-genes-0201; 6% of liver cell transformations are sufficient for disease curing, which is 15 times more effective than other methods, but the group hope to boost this % in future. 

2. Better DNA Aptamer Technology
DNA aptamers can be artificially engineered to target and bind any molecular target in the body - proteins, viruses, bacteria, cells, tumours - but are limited by poorer binding-efficiency and instability due to enzymatic digestion. These two limiting factors have now been addressed http://www.a-star.edu.sg/Media/News/Press-Releases/articleType/ArticleView/articleId/4496.aspx with (i) the inclusion of an artificial base into the DNA that boosted binding ability by 100 times compared to existing aptamers, and (ii) the inclusion of a DNA-mini-hairpin structure that serves to restrict enzymatic digestion and boost lifetime in the body from hours to days. DNA aptamers like these could in theory be used instead of antibodies for therapeutic and diagnostic applications but are cheaper, quicker, and simpler to produce and obviate potential inflammatory side effects. 

3. Developing a Light-Effect-Transistor
Prototype light effect transistors have been developed with the aim of replacing standard field effect transistors in future chip designs https://www.technologyreview.com/s/600702/the-nanodevice-aiming-to-replace-the-field-effect-transistor/. A light effect transistor comprises a wire that conducts electricity when exposed to light and insulates when it is dark; a light-controlled switch in which light functions like a gate and with benefits including no reliance on dopant atoms and the ability to achieve smaller size dimensions to continue Moore’s Law. The demonstrations include semiconducting nanowires whose conduction changes by six orders of magnitude when switched, and can also function as an optical amplifier that performs logic operations when two or more laser beams are used. But the biggest unsolved question is how a chip would accurately address more than a billion nanowires with light? 

4. Rejuvenation via Senescent Cell & Amyloid Clearance 
First, venture-backed company Unity Biotechnology joins competition with Oisin Biotechnology aiming to develop and launch therapeutics that clear senescent cells from adult animals https://www.fightaging.org/archives/2016/02/25-median-life-extension-in-mice-via-senescent-cell-clearance-unity-biotechnology-founded-to-develop-therapies.php. Their latest work extends the median lifespan of mice by 25% and should help to attract additional funding and support for this approach; investors will want to get this into humans as soon as possible. And back in the lab another group finds a 35% lifespan extension by clearing senescent cells http://newsnetwork.mayoclinic.org/discussion/mayo-clinic-researchers-extend-lifespan-by-as-much-as-35-percent-in-mice-2/. Second, a partnership between companies Pentraxin and GSK is slowly bearing fruit with clinically-tested drug therapies that very effectively clear amyloid (misfolded protein clumps that accumulate) deposits from tissues and body fluids, intended for Alzheimer’s and other diseases but providing a platform for this area of rejuvenation therapies https://www.fightaging.org/archives/2016/02/what-next-for-transthyretin-amyloid-clearance-therapies.php. Boosting mitophagy also rejuvenates cells to a more youthful state http://www.eurekalert.org/pub_releases/2016-02/nu-mst020316.php. 

5. Atomically Precise Materials and Devices
Structural DNA technology can self-assemble nanoparticles into diamond-shaped crystal lattices https://www.bnl.gov/newsroom/news.php?a=11810. The DNA forms the rigid frame of the material, while complementary DNA binding ensures the nanoparticles bind in specific locations, leading to a diamond lattice about 100 times larger than conventional diamond; interesting platform for novel materials development. Bacteria produce self-assembled microcompartments to concentrate enzymatic production of certain molecules, and these compartments are being used as templates to engineer variants with novel functions and molecular production capabilities https://newscenter.lbl.gov/2016/02/04/toward-nanoscale-chemical-factories/, slowly building a platform of contained molecular production machinery that might one day be introduced inside human cells for exmample. 

6. NASAs Integrated Photonics Modem
NASA is building the first fully integrated photonics modem, simplifying optical on-chip systems design, and reducing the size of the large prototype down to conventional system-on-chip scales http://www.nasa.gov/feature/goddard/2016/nasa-engineers-tapped-to-build-first-integrated-photonics-modem. The chip uses lasers to encode and transmit data at 10 - 100 times faster than equipment available today. While testing of the device in space won’t begin until 2020 we might see commercial applications of this earlier, particularly in data centers and Internet backbone lines. 

7. Electronic Nematicity Key in Superconductivity
New studies indicate that the phenomenon of electronic nematicity, in which electron clouds in a material snap into an aligned and directional order, is a generic property common to high-temperature superconductors https://uwaterloo.ca/stories/waterloo-physicists-discover-new-properties. The electrons involved in superconductivity form patterns that exhibit different symmetries that preferentially align in one direction and which can compete with, co-exist, or enhance superconductivity. Hopefully this understanding allows for the future design of higher-temperature superconductors. 

8. Dedicated Deep Learning Chips on Smartphones
Eyeriss is a newly designed and developed dedicated deep learning chip for use in smartphones and other low-power applications http://spectrum.ieee.org/tech-talk/semiconductors/processors/a-deep-learning-ai-chip-for-your-phone. The chip is designed to allow these devices to run computationally demanding neural network algorithms quickly and efficiently on the device without offloading to the cloud, and using only one tenth of the energy of a typical mobile GPU. Agnostic to the type of neural network being run the chip can process image, sound, and other types of data as  needed and might also find deployment in autonomous platforms such as cars and drones. In related news Google’s DeepMind game-playing AI can now also navigate environments in first-person-shooters https://www.newscientist.com/article/2076552-google-deepmind-ai-navigates-a-doom-like-3d-maze-just-by-looking/ and I wonder if this can be transferred to robots to help in realworld environments, perhaps by using these dedicated chips. 

9. Graphene Lenses and Electrode Benefits
First, graphene has been formed into a clever fresnel lens by using a laser to pattern concentric rings of graphene oxide on its surface, and allowing optical focusing in the visible and infrared down to scales of 200nm http://www.swinburne.edu.au/news/latest-news/2016/01/focus-on-results.php. Second, graphene-coated electrodes turn out to be an excellent option for applications involving interfacing with neurons http://graphene-flagship.eu/graphene-based-interfaces-do-not-alter-target-nerve-cells. Finally, graphene cages formed around silicon anodes appear to enable higher capacity batteries that avoid the problem of cracking that such materials are usually limited by http://spectrum.ieee.org/nanoclast/semiconductors/materials/graphene-cages-cover-silicon-anodes-for-high-capacity-batteries. 

10. Flexiramics: Ceramics that Act Like Paper
A new material dubbed flexiramics is being developed and commercialised by a company called Eurekite http://arstechnica.com/science/2016/02/dutch-researchers-have-created-flexiramics-flexible-ceramics-for-circuit-boards/. Flexiramics appear to be a new class of materials that possess the mechanical properties of paper or thin textiles in being thin, foldable, and flexible while also exhibiting the properties of ceramics in being fireproof and nonconducting. The fabrics withstand 1,200 degrees Celsius for 24 hours without burning or melting. Printed PCBs will be the first application apparently but the possibilities are endless.

A new MIT computer chip could allow your smartphone to do complex AI tasks

Yesterday, a team of researchers from MIT introduced a new computer chip optimized for deep-learning, an approach to artificial intelligence that is gaining popularity. The chip, dubbed "Eyeriss" could allow mobile devices to perform tasks like natural language processing and facial recognition without being connected to the internet. It’s the latest attempt to make the complex operations of machine learning more portable. That means that our smartphones, wearables, robots, self-driving cars, and other IoT devices could begin performing complex deep learning processes locally — something that until now has been very difficult to do.

SciTech #ScienceSunday Digest - 04/2016.
Permalink here: http://www.scitechdigest.net/2016/01/gut-microbe-therapeutics-better-brain.html

Gut microbe therapeutics, Better brain imaging, Superfluid knots, Weaving molecular chains, New brain insights, Living microdroplet reactors, Fermi Paradox nonequilibrium, Memristor chips on market, Modular food computer, Graphene advances.

1. Therapeutics via the Gut Microbiome
Seres and Synlogic are companies trying to launch modified bacteria as drugs designed to live in and complement the human gut microbiome http://www.technologyreview.com/news/545446/companies-aim-to-make-drugs-from-bacteria-that-live-in-the-gut/. Seres wants to introduce specially-selected bacteria into the gut to help restore a healthy microbiome, while Synlogic wants to introduce genetically modified bacteria designed to take up residence and perform useful functions such as metabolising toxins and other compounds that some people have trouble with. I’ve been thinking about different ways you might functionalise the gut microbiome in beneficial ways for years now and think the opportunities here are immense - it’s good to see these early approaches entering clinical studies but I worry if they go the conventional route they might suffer similar difficulties to that of bacteriophage therapies.

2. Better Brain Imaging and Sensors
The nVista system is an implantable miniature microscope that allows researchers to track brain activity in mice in realtime http://gizmodo.com/gopro-for-mouse-brains-records-neural-circuits-in-real-1746582790. The device is very light to allow animals to move around relatively unobstructed and is capable of tracking the activity of up to 1,000 individual neurons simultaneously. In related news a new type of tiny sensor can be implanted to monitor brain temperature and pressure and then later dissolve away when no longer needed; measurements are conveyed via an implanted wireless transmitter https://news.illinois.edu/blog/view/6367/312684 - the group are moving towards clinical trials and exploring other application areas.

3. Tying Complex Knots in Superfluids
After preparing a superfluid a new technique involving targeting the superfluid with rapidly changing and specifically structured magnetic fields allows the superfluid to be tied in knots; quantum knots in the form of a self-reinforcing soliton comprised of a toroidal ring structure in three dimensions https://www.amherst.edu/news/news_releases/2016/01-2016/node/626688. This builds on previous work in which the group used similar techniques to create synthetic magnetic monopoles. This is a very interesting new natural phenomenon to explore and harness and the group will continue to probe the properties of these knotted superfluid objects.

4. New Materials from Woven Molecular Chains
The first three dimensional covalent organic framework materials have been created by weaving together helical organic threads http://newscenter.lbl.gov/2016/01/21/weaving-a-new-story-for-cofs-and-mofs/. This should result in a new generation of materials with novel properties stemming from the base structure of individual molecular chains being woven together in a precise, ordered, and controlled way. Removing metal from the chains resulted in a 10-fold increase in elasticity of the material while adding metal restored the materials original stiffness. The technique has generalities in that it should allow many long threads of covalently-linked molecules to be woven and cross-together at regular intervals and is applicable to metal organic frameworks, nanoparticles, and polymers.

5. New Brain Insights
We had a trio of interesting brain insights this week. First, it appears synapses can vary in size in far greater increments than originally thought, resulting in estimates for the memory capacity of the human brain being revised upwards by an order of magnitude and helping to explain the computational efficiency of the hippocampus for example http://www.salk.edu/news-release/memory-capacity-of-brain-is-10-times-more-than-previously-thought/; every 2 - 20 minutes your synapses go up or down to the next size. Second, network analysis of brain activity reveals that 70% of all information within cortical regions passes through just 20% of the region’s neurons, further supporting the brain’s preference for efficiency over vulnerability http://news.indiana.edu/releases/iu/2016/01/hub-neurons.shtml. Finally, new micro-tissue engineered neural networks are small columns of biomaterial through which neurons have grown axons and which, when implanted, can connect neuronal populations in the brain (and possibly elsewhere) and replace damaged axonal tracts http://www.uphs.upenn.edu/news/News_Releases/2016/01/cullen/.

6. Mimicking Living Systems with Microdroplet Reactors
A new microfluidic system promises better, easier bioreactors for synthetic biology applications http://phys.org/news/2016-01-microdroplet-reactors-mimic.html. The new system first establishes water-in-oil test sites in discrete wells formed in the microfluidic chip, with each site bordered by electrodes able to apply an AC voltage over the site; water-in-oil droplets introduced in a digital fashion to the channels flow past the reaction sites and (i) when AC is applied the droplets fuse to the site, while (ii) the shear force of the travelling droplets induces fission and the droplet travelling on. Fusion uses the travelling droplets to introduce new molecules to the sites, while fission can carry away waste products, production products, or signalling products for collection and analysis. This does away with complex valves and mixers and is able to maintain chemical reactions in the sites far from equilibrium. In related news a new microfluidic microbubble technique efficiently produces liposomes for study, drug delivery, and artificial cell applications http://phys.org/news/2016-01-closer-artificial-cell-divisionby.html.

7. Fermi Paradox and Planetary Extinction
A new study on early planetary environments and life suggests a “Gaian Bottleneck” that prevents life from evolving beyond the simple single-celled stage, essentially operating as an early Great Filter preventing the rise of complex intelligent life on otherwise habitable planets thought to be ubiquitous throughout the galaxy http://www.anu.edu.au/news/all-news/the-aliens-are-silent-because-they-are-extinct. The authors suggest that new life commonly dies out on fledgling new worlds due to runaway heating or cooling arising from the unstable nature of young planetary environments, and before life has a chance to evolve a complex global ecosystem of simple organisms capable of regulating atmospheric gases.

8. Commercial Offerings of Memristor Chips
Knowm has launched a portfolio of three memristor chip products made available to customers seeking to include the chips in their computing hardware http://www.eetimes.com/document.asp?doc_id=1328733. Memristors can act as emulators of synapses and brain networks with the promise of offering brain-like computing and energy efficiency; such chips will have powerful deep learning and neural network emulation applications across a range of areas in future. The commercial availability of memristor-based chips is great news although we’ll have to wait and see when they make their way into consumer-facing products and services.

9. Open Source Food Computer
The Food Computer from the Open Agriculture Initiative is a new platform seeking to standardise indoor hydroponics and plant cultivation and so better enable rapid growth, industrial scale, cost efficiencies, and accessibility for the sector http://spectrum.ieee.org/computing/embedded-systems/mits-food-computer-the-future-of-urban-agriculture. The Food Computer is an advanced indoor plant cultivator and hydroponic system that precisely monitors and controls light exposure temperature, humidity, CO2, water cycle, and nutrient exposure to create an optimal “recipe” for each type of plant. The system is inherently modular with Food Computers coming in (i) Personal Food Computer, (ii) Shipping Container, and (iii) Warehouse Scale sizes for personal, small scale, and large scale use - and all benefiting from cheaper and better sensors, computers, and lighting.

10. Graphene, Graphene, and More Graphene
First, a new spongy graphene elastomer functions as a flexible ultra-light pressure and vibration sensor that far exceeds the response range of human skin http://monash.edu/news/show/revolutionary-new-graphene-elastomer-exceeds-sensitivity-of-human-skin. Second, terahertz frequency lasers can now be made tunable thanks to the combination of graphene with a quantum cascade laser http://www.graphene.manchester.ac.uk/latest/?archive=twelvemonths&id=15750. Third, simulations show that fast and accurate DNA sequencing is possible by passing DNA through functionalised graphene nanopores http://www.nist.gov/mml/acmd/nist-simulates-fast-accurate-dna-sequencing-through-graphene-nanopore.cfm. Fourth, specific and controllable placement of molecules is possible via graphene sheets decorated with custom patterns http://newsroom.ucla.edu/releases/ucla-scientists-create-graphene-barrier-to-precisely-control-molecules-for-making-nanoelectronics. Finally, graphene nanoelectromechanical systems can controllably modulate the emission of light from single-photon nanodiamond emitters http://phys.org/news/2016-01-on-chip-nano-optics-graphene-nano-opto-mechanics.html.

New study indicates students' cognitive functioning improves when using standing desks

Do students think best when on their feet? A new study by the Texas A&M Health Science Center School of Public Health indicates they do. Findings published recently in the International Journal of Environmental Research and Public Health provide the first evidence of neurocognitive benefits of stand-height desks in classrooms, where students are given the choice to stand or sit based on their preferences.

"Test results indicated that continued use of standing desks was associated with significant improvements in executive function and working memory capabilities," Mehta said. "Changes in corresponding brain activation patterns were also observed."

Hey everybody! I just want to give a health tip for this season. To avoid becoming sick, you can use the power of Zinc and Vitamin C to help you maintain your Immune System. Everyone is pretty familiar with Vitamin C which you can get from Green Peppers and Oranges so I will focus on Zinc. You can mainly get Zinc from Cashews and Oysters. You can also get Zinc and Vit C both from Emergen-C which you can find in most local food stores.

Lastly, simply gargling with salt water may help make your body inhospitable to unwanted microbes during the winter.

Cheers to Optimization my friends.

So AGE-blocking substances may chemically benefit aging, stressed, or damaged brains. If you are an advocate for someone with Alzheimer's, autosm, ADHD, or simply have a passion for throwing disposable income towards optimal health and human performance, I'd recommend Lyposoheric B Complex Plus for this. But check with your doctor first.

If you are an advocate for someone with Alzheimer's, autosm, ADHD, or simply have a passion for throwing disposable income towards optimal health and human performance, I'd recommend Lyposoheric B Complex Plus for this. But check with your doctor first.___

SciTech #ScienceSunday Digest - 01/2016.
Permalink here: http://www.scitechdigest.net/2016/01/crispr-in-adults-cheap-genome.html

Short week for the first week and holiday week.
CRISPR in adults, Cheap genome sequencing, Better brain algorithms, Intracellular chips, Smartphone 3D scanning. 

1. CRISPR Corrects Genetic Defect in Adult Animal
CRISPR has been packaged into an adeno-associated virus (AAV) delivery vector for the first time to treat Duchenne muscular dystrophy in mice http://today.duke.edu/2015/12/crisprmousedmd. One of the key advances here was using a different CRISPR system from another bacterial species that was smaller and able to fit inside the virus. The therapy worked for both direct injection into muscles and also, most importantly, injection into the bloodstream that resulted in some correction of muscles throughout the body including the heart. Perhaps multiple rounds might increase percentage of cell coverage each time, and engineering or evolving larger AAVs able to deliver larger payloads would also be advantageous. Such an advance is as important for disease as it is for enhancements. 

2. Genome Sequencing for $330
Full Genomes is a company now offering possibly the cheapest ever genome sequencing services and using conventional Illumina DNA sequencing platforms http://nextbigfuture.com/2016/01/whole-genome-sequencing-for-330.html. $330 is the cheapest rate with interpretation, but up to $1,600 orr so will get you 30-fold coverage of your genome for much better accuracy; the final DNA sequence file is about 50GB in size. This is a pretty impressive price and one that is becoming sorely tempting; I wonder what the price will be in five years and also how many hundreds of times I’ll be sequenced in a couple of decades?

3. Brain Architecture and Abstract Thought
New Big Data analysis pulling together 20 years of fMRI data has resulted in a new geometry-based method for understanding human thought and cognition https://www.umass.edu/newsoffice/article/how-brain-architecture-leads-abstract. The analysis showed that an agglomeration of many different cortical areas give rise to cognitive function and abstract thought, showing a basic operational paradigm of cognition that consists of certain hierarchies. The group expect the new geometric algorithm to be a very useful data science tool moving forward and will also help with the design of next generation neural networks and deep learning systems; they are using the new approach to make a massively recurrent deep learning network for a more brain-like and superior learning AI.

4. Inserting Chips Into Cells
Multiplexed silicon planar arrays have been reduced in size by a factor of a billion, producing devices that measure just three micrometers on a side and which are able to be inserted into individual cells, taking up just 0.35% of the cell volume, and allowing multiple tests and analysis on individual cells http://www.nanowerk.com/spotlight/spotid=42212.php. These chips can be functionalised and interrogated via confocal laser scanning microscopy to determine various physicochemical intracellular parameters. I wonder what other functions and logic we’ll building into intracellular chips like this?

5. 3D Scanning via Smartphone
A new image capture method using structured lighting on an object and novel algorithms allow simple devices like smartphones to perform high-quality 3D depth-scanning and produce 3D images and models http://www.kurzweilai.net/algorithm-turns-smartphones-into-3-d-scanners. The key innovation here is that the algorithms can work without needing the camera to be synchronised to the source of the structured light patterns being projected onto the object. Closer and closer to cheap ubiquitous 3D scanning capabilities.

SciTech #ScienceSunday Digest - 52/2015.
Permalink here: http://www.scitechdigest.net/2015/12/spacex-rocket-success-cheaper-dna.html
Merry Xmas and Happy New Year to all from SciTech Digest! 

SpaceX rocket success, Seabed mining robots, Cheaper DNA synthesis, Machine learning projects, Boosting brain cleaning, Electron beam nanofabrication, Optoelectronic chips, Intelligence gene networks, Plant virus vs cancer, Protein self assembly. 

1. SpaceX Successfully Lands Reusable Falcon 9 Rocket
In easily the biggest news of the week SpaceX successfully landed its reusable Falcon 9 rocket after launching 11 communications satellites into orbit http://www.space.com/31420-spacex-rocket-landing-success.html. After two prior landing failures and a launch failure this milestone is a welcome, if not entirely unexpected, demonstration. It marks the first time an orbital rocket has delivered a payload into orbit and returned to Earth unscathed and ready for refurbishment and relaunch. Further tests to replicate the feat and build on the capability will result in drastic reductions in the cost of ferrying mass to space and help usher in new space-based applications and capabilities for our species. 

2. Robots that Mine the Seabed
The first deep sea seabed mining robots have been developed and will be tested throughout 2016-17 until the arrival of their first deployment and processing ship, which is currently under construction http://spectrum.ieee.org/robotics/industrial-robots/seabedmining-robots-will-dig-for-gold-in-hydrothermal-vents. After ripping up ore from the seafloor dredge pumps carry the rock to the surface where the deployment ship removes the water and transfers the ore to another ship for transport to China for processing (I do wonder if this step can ever be co-located with the main ocean operations). Over 30 months the robots will bring up 2.5 million tons of ore with metals worth $1.5 billion. 

3. DNA Synthesis Races to the Bottom
New start-up companies are developing technology to manufacture and synthesise DNA sequences faster and cheaper than ever http://spectrum.ieee.org/biomedical/devices/dna-manufacturing-enters-the-age-of-mass-production. A key part of this trend is increasing automation of the synthesis process with one example being an automated synthesis process taking part in each of the 10,000 tiny etched 600-nm wells adoring a new silicon synthesis chip that is fabricated with standard photolithography processes and will start providing customers with DNA at 10 cents per base pair but aiming for 2 cents in the foreseeable future. While cheap synthesis doesn’t help quite so much once you have a desired cell and application, cheap synthesis does help greatly with rapid iteration, accelerated experimentation, and distributed development. 

4. Big Week for Machine Learning Applications
First, a new machine learning system based on new object-recognition algorithms that more closely resemble how the human brain recognises objects requires only a few exposures rather than millions http://news.mit.edu/2015/algorithms-recognize-objects-few-examples-1223. Second, computers are being taught via human crowdteaching how to successfully tackle difficult driving tasks, and this might open up similar avenues to teach robots etc how to master other non-trivial tasks http://www.technologyreview.com/view/544926/ai-machine-learns-to-drive-using-crowdteaching/. Third, SegNet is a new system able to run on a normal camera or smartphone able to efficiently and quickly identify location, orientation, and various components in the scene ahead to better empower autonomous vehicles http://www.cam.ac.uk/research/news/teaching-machines-to-see-new-smartphone-based-system-could-accelerate-development-of-driverless-cars. Finally, a new deep-learning algorithm can predict an images memorability at near-human levels https://www.csail.mit.edu/memnet_photo_memorability. 

5. Boosting Brain Cleaning System Boosts Cognition
Rolipram, a drug originally developed in the 1990s but which never made it to market due to nausea-inducing side effects, has been found to rescue and activate the proteasomes in neurons and helps to boost cognition in mouse models http://newsroom.cumc.columbia.edu/blog/2015/12/21/improving-brains-garbage-disposal-may-slow-alzheimers-disease/. The proteasome is an enzyme that degrades old proteins for recycling and its inactivity is involved in neurodegenerative diseases characterised by a buildup of old toxic proteins; better, safer drugs and other interventions building on this work will be attractive options for treating Alzheimers, Parkinsons, and Huntingtons Disease, as well as helping to generally rejuvenate cells and tissues throughout the body. 

6. Electron Beam 3D Nanofabrication
A liquid rather than gaseous precursor has helped speed up electron beam 3D nanofabrication by up to 5,000 times, finally helping to scale this promising technology http://spectrum.ieee.org/nanoclast/semiconductors/nanotechnology/electron-beam-nanofabrication-made-up-to-five-thousand-times-faster. The proof of concept demonstrated micrometer-tall nanopillars and suspended 3D nanostructures; the new technique and new precursors should allow for the rapid development and fabrication of electrode surfaces for batteries and fuel cells, vertically-stacked electronic memory, novel substrates for cell manipulation, and nano-micro-scale electrochemical conversion devices. 

7. Latest Optoelectronic Computer Chips
Optical interconnects in integrated circuits have been a long time coming but this latest effort sees genuine commercial scale integrated circuits built using existing microchip fabrication facilities and processes that incorporate new photonic / optoelectronic interconnects; the transistors compute information conventionally but the chip uses light to move information around the chip much more efficiently http://news.mit.edu/2015/optoelectronic-microprocessors-chip-manufacturing-1223. The demonstration chip has 70 million transistors and 850 optical components and is capable of the functionality required of a typical commercial chip, and with a relatively clear path to get to the billion transistor scale needed for modern chips. Lots of interesting materials and chip design innovation here. 

8. Gene Networks Linked to Human Intelligence
A Big Data analysis of gene expression profiles from human brain samples, genomic information from both healthy people who had completed IQ tests and also those with neurological disorders has identified two gene networks, each with hundreds of genes, that significantly influence intelligence and cognitive function in the human brain http://www3.imperial.ac.uk/newsandeventspggrp/imperialcollege/newssummary/news_22-12-2015-10-13-44. Both networks appear to be under the control of master regulator switches that the group are now seeking to identify. The group hopes the knowledge gained will help in the development of treatments for neurological disorders and also powerful enhancers for healthy cognitive function. 

9. Plant Virus Clears Mammalian Cancer Cells
Turns out that the shells of common plant viruses (that have had their DNA removed) induce significant immune responses against cancer cells in mice http://phys.org/news/2015-12-simple-shell-virus-immune-response.html. This demonstration was successful in lung tumours when the viral shells were inhaled and also when injected into ovarian, colon, or breast tumours, in all cases igniting immune responses to clear the tumours and protect the animal against systemic metastases. Such in-situ vaccinations are a 100 year old idea and in this case proved to be a very effective switch in activating the immune system to recognise and destroy the tumour cells - essentially a biological adjuvant. 

10. Structural Nanotechnology: Protein Sheets & Shells
Bacterial proteins have been observed self-assembling into sheets, and curved sides of microcompartments as they form for the first time http://phys.org/news/2015-12-nature-masonry-thin-protein-sheets.html. The group observed hexagonal protein subunits with a concave or convex structure joining together to form larger curved structures and modelled the dynamics of this behaviour. It is known that bacteria use such self-assembled protein microcompartments to isolate certain reactions and enzymes; such knowledge might help in the design of artificial microcompartments to perform custom reactions inside cells and other structures.

#ScienceSunday   #Science  

SciTech #ScienceSunday Digest - 50/2015.
Composed at 36,000 feet. Posted live from LAX at 11:00pm Saturday because Sunday won’t exist for me!
Permalink here: http://www.scitechdigest.net/2015/12/autonomous-computer-produced-text-faces.html

Autonomous computer-produced text, faces, animation, and artworks, Drone swarm vs fires, Bio-powered CMOS, Periodic table of proteins, DNA electromechanical switch, Better DNA/RNA delivery, 3D skyscraper chips, Kill-switches for bacteria. 

1. Human-Like Character Drawing by Computer
A new computer system can produce written characters in a human-like fashion, producing variations of a character in an unfamiliar writing system on the first try that is indistinguishable from that of humans http://news.mit.edu/2015/computer-system-passes-visual-turing-test-1210. The system essential general structures of a character while accounting and reproducing minor inessential variations and fooled human judges to pass a “visual Turing test” of human indistinguishability. 

2. Automatic Face Construction & Animation
New machine learning algorithms can take many images of a person (even trawling the Web if needed) and automatically create a digital model of the person’s face that it can then animate, overlaying it onto a second person’s speech or video to make it appear as if the person is accurately performing a speech that they never actually gave http://www.washington.edu/news/2015/12/07/what-makes-tom-hanks-look-like-tom-hanks/. Proof-of-concept was performed with celebrities, and one might imagine video production costs being reduced by such a system in future. 

3. Artificial Computational Artworks
In related news this week we had a couple of advances for computers creating detailed artifiical images on demand. First, Facebook’s AI team and machine learning company indico developed an artificial neural network able to produce realistic but “imagined” images on demand https://www.newscientist.com/article/dn28548-computers-learn-to-create-photos-of-bedrooms-and-faces-on-demand/. The proof-of-concept produced realistic but made-up images of bedrooms and faces. Second, WordsEye is a new webapp that translates a few lines of user text to produce an artistic representation of a scene https://www.washingtonpost.com/news/innovations/wp/2015/12/01/when-artificial-intelligence-makes-a-picture-worth-way-more-than-a-thousand-words/, an interesting application that allows basic “type a picture” applications. 

4. Cooperative Drones Extinguish Fires
Lockheed Martin has demonstrated its autonomous fire fighting drones http://spectrum.ieee.org/automaton/robotics/aerial-robots/lockheeds-drones-fires. The drones monitor areas for fires, identify fires in those areas, can call in support and provide targeting coordinates for the drones in the team and then the larger drones deliver a precise water drop over the area. What else might the system be used for? Shark spotting, avalanches, oil spills? Obvious military applications. 

5. Biologically-Powered CMOS Chip
Researchers have integrated a conventional solid-state CMOS chip with an artificial lipid bilayer membrane containing ATP-powered ion pumps http://engineering.columbia.edu/columbia-engineers-build-biologically-powered-chip-0. In the presence of ATP the system pumps ions across the membrane, producing a electrical potential that can be harvested by the CMOS integrated circuit. This has huge potential as a human-body power-source for any implanted device. But by changing the ion pump you could make systems that can sense molecules with biological-like sensitivity. 

6. Unveiling a Periodic Table of Protein Complexes
A periodic table of protein complexes, specifically protein quaternary structure topologies, has been developed that is compatible with 92% of known protein structures and which provides significant predictive power for developing new proteins http://www.genengnews.com/gen-news-highlights/periodic-table-of-protein-complexes-unveiled/81252091/. This not only provides a better way of looking at protein strucutres found in nature but also of engineering new proteins that evolution may never have discovered. The work builds on principles of protein assembly and helps explain basic steps, repeated in different combinations, gives rise to an enormous variety of different proteins. 

7. Electromechanical Switch Made of DNA
A reversible electromagnetic switch was engineered out of DNA in which modifications to the environment induced structural changes in the DNA strand and this in turn resulted in a change in conductance of the DNA http://phys.org/news/2015-12-dna-based-electromechanical.html. A tantalising discovery, but still in need of a huge amount of work in order to self-assemble huge numbers of such switches into logic gates for next generation computers, not least of which will be finding an alternative method to alter the environment, which currently involves adding and removing ethanol. 

8. Better Delivery of DNA/RNA into Cells
There were a couple of advances in this area this week. First, a new water-in-oil droplet electroporation gene-transfection method has been developed that is able to more efficiently and cheaply deliver DNA into cells, and requires fewer cells and a smaller amount of DNA http://phys.org/news/2015-12-method-genes-cells.html. Second, microRNAs wound together as triplet molecules and embedded into a biocompatible gel have proven remarkably effective in delivering specific microRNA sequences to cancer cells in mice and dramitcally improving survival rates http://news.mit.edu/2015/microrna-shrink-tumor-cancer-treatment-1207 - the approach should also work with DNA. 

9. Performance Boosts from Skyscraper Chips
The N3XT computing architecture seeks to push the design and fabrication of integrated circuits into the third dimension by fabricating interlinked layers of memory and processors, one atop the other, and connected by millions of vias http://news.stanford.edu/news/2015/december/n3xt-computing-structure-120915.html. One of the key insights here to enable the architecture is much lower temperature fabrication methods and forcing a move away from silicon and towards carbon nanotube transistors. Prototype proof-of-principle devices have been built and simulations suggest that the architecture could be 1,000 times more efficient compared to conventional chips. 

10. Kill-Switches for Engineered Bacteria
Two genetic kill-switches have been developed for engineered bacteria in order to both (i) enable useful genetically engineered bacteria to be developed and widely used, and (ii) prevent such tools from “running off” and colonising areas where they are not supposed to be http://news.mit.edu/2015/kill-switches-shut-down-engineered-bacteria-1211. These stand alone genetic circuits, which can be dropped into any engineered bacterial organism (and repurposed for others?) involve (i) a Deadman Switch that continuously produces a toxin that kills the cell unless there is another artificial chemical in the immediate environment, and (ii) a Passcode Switch that requires a specific combination of several chemicals in order to allow the cell to survive and proliferate.

"The stomach might better be called a dissolver, the small intestine an absorber, and the colon a transformer."

To gain an appreciation of the human colon and the role of microbes in the digestive tract as a whole, it helps to follow the metabolic fate of a meal. But, first, a word about terms. We’ll refer to the digestive tract as the stomach, small intestine, and colon. While the colon is indeed called the “large intestine,” this is a misnomer of sorts. It is no more a large version of the small intestine than a snake is a large earthworm.

Just as physical conditions like temperature, moisture, and sun strongly influence the plant and animal communities that one sees on a hike from a mountain peak to the valley below, the same holds true along the length of the digestive tract.___

This is amazing. Science is beginning to realize how our thoughts and emotions impact biochemistry and produce cascades of changes in epigenetic methylation and even telomere lengthening.

Transcendental Meditation, lifestyle modification increase telomerase - which is linked with lifespan

A new study published in PLOS ONE found that the Transcendental Meditation technique and lifestyle changes both appear to stimulate genes that produce telomerase, an enzyme that's associated with reduced blood pressure, cardiovascular disease, and mortality.

'Healthy' foods differ by individual - the start of personalized nutrition

Ever wonder why that diet didn't work? An Israeli study tracking the blood sugar levels of 800 people over a week suggests that even if we all ate the same meal, how it's metabolized would differ from one person to another. The findings, published November 19 in Cell, demonstrate the power of personalized nutrition in helping people identify which foods can help or hinder their health goals.

Starting soon, Uber drivers looking to earn some extra money on their commutes to and from home — especially those who drive part-time — will be able to with the ride-hailing app's new "destinations" feature. Drivers heading in a specific direction can input their destination into the app, and Uber's algorithm will send them ride requests that appear along the way. Requests that would force them to deviate from their route would be filtered out.

1. 3D Nanometer Structures with Electron Microscopy
Scanning transmission electron microscopes can now be used to sculpt nanometer-sized 3D features in oxide materials https://www.ornl.gov/news/new-electron-microscopy-method-sculpts-3-d-structures-atomic-level. The technique offers single plane atomic precision and produces structures whose composition is in perfect crystal alignment and so ensuring uniform electromechanical properties - further, these structures can be generated deep within the bulk substrate, below the surface in a controlled manner. Current resolution is about 2nm and involves an electron beam transferring energy to individual atoms. 

2. Ultrasound to Open the Blood Brain Barrier
Focused ultrasound can now be used non-invasively open the blood brain barrier to allow the passage of drugs and other molecules as desired http://sunnybrook.ca/media/item.asp?i=1351. As part of the demonstration the group successfully delivered a chemotherapy drug through the blood brain barrier to target a malignant brain tumour. Interestingly this is a physical effect, relying on the injection of microbubbles into the bloodstream, and MRI-guided focused low-intensity ultrasound to blood vessels in the desired region of the brain, causing the microbubbles to contract and expand, vibrating the BBB and making it permeable. This was also apparently two decades in the making with an industry partner, so should have a higher chance of making a wider impact.  

3. Deep Learning the Many Things
There were a bunch of interesting deep learning stories this week. First and foremost was Google’s announcement to open-source its TensorFlow deep learning system to allow anyone to benefit from the same powerful tool that powers much of the intelligence in many Google products https://googleblog.blogspot.com.au/2015/11/tensorflow-smarter-machine-learning-for.html. Second, Enlitic’s deep learning system is significantly better than radiologists at detecting cancer from CT scans http://singularityhub.com/2015/11/11/exponential-medicine-deep-learning-ai-better-than-your-doctor-at-finding-cancer/. Third, deep learning algorithms are becoming better than humans at spotting lying from facial expressions https://www.newscientist.com/article/mg22830462-700-lie-detecting-algorithm-spots-fibbing-faces-better-than-humans, and are also learning to spot hidden human microexpressions http://www.technologyreview.com/view/543501/machine-vision-algorithm-learns-to-recognize-hidden-facial-expressions/. 

4. Making Better Brain Computer Interfaces
Work progresses on using precise magnetic fields to stimulate 20nm iron oxide nanoparticles injected into desired areas of the brain that can active neurons when stimulated http://news.sciencemag.org/brain-behavior/2015/03/magnetic-rust-controls-brain-activity. This builds on earlier work, showing that magnetic fields plus magnetic nanoparticles can be used to not only stimulate neurons in the cortex but also in deep areas of the brain, and was proven in mice that expressed fluorescent protein in those areas stimulated. In related news better neural-signal-decoding algorithms have been developed http://spectrum.ieee.org/tech-talk/biomedical/bionics/better-brainreading-software-compensates-for-squishy-brains-and-vacuum-cleaner-noise, and a neurologist and BCI inventor takes the ultimate step by having a BCI implanted into his own healthy brain http://www.technologyreview.com/news/543246/to-study-the-brain-a-doctor-puts-himself-under-the-knife/. 

5. Better Optogenetics Tools
In a significant step for optogenetics flexible, stretchy, wireless light-emitting electronic implants have been developed that solve a number of problems that rigid optogenetic implants possess http://spectrum.ieee.org/tech-talk/biomedical/bionics/flexible-implants-hack-the-sense-of-pain. The implants were successfully demonstrated in mice; their flexibility allowed them to be sutured in place, and once wirelessly powered they were able to activate the sensation of pain in the mice after having their sensory nerve cells engineered to produce the optogenetic protein. Such a device might be used to block pain in humans in future. In related news new techniques have been developed with infrared light to allow deep-brain imaging (and stimulation) in ways not before possible https://www.ccny.cuny.edu/news/ccny-researchers-open-%E2%80%9Cgolden-window%E2%80%9D-deep-brain-imaging. 

6. Improved Artificial Model of Biological Neurons
Jeff Hawkins has released a new model of neurons that explains a number of different known phenomena, including the vast number of synapses in real neurons and memory functions like chunking, and also makes testable predictions for the behaviour and features of neurons that can be confirmed in future http://www.technologyreview.com/view/543486/single-artificial-neuron-taught-to-recognize-hundreds-of-patterns/. The model divides a neuron’s synapses into proximal and distal connections, which play entirely different roles in the process of learning. Proximal synapses trigger the cell to fire when certain patterns of connections occur, while distal synapses recognise patterns not to trigger firing but to set the cell up for the arrival of certain other patterns and in a way predicting what that should be. Not just patterns but the sequence of patterns. If confirmed such models will lead to improved neuromorphic computing and deep learning systems.

7. Creating a Porous Liquid
The term “porous liquid” was impossible to pass up. Chemists have created free-flowing liquids whose properties are determined by permanent porosity, and which are comprised of cage molecules that are soluble in solvents whose molecules are too big to enter the cages https://www.qub.ac.uk/home/ceao/News/Title,539041,en.html. The key depends on the solvent of course but nonetheless the concentration of unoccupied cages can enable up to eight times more methane or other gases to be dissolved in the liquid by being captured and stored in the molecular cages. An interesting material with useful properties and applications that we can’t fully imagine right now. 

8. Plant Growth Boost with Nanoparticles
Titanium dioxide and zinc oxide nanoparticles, when applied as a fine spray onto the leaves of tomato plants, results in bigger, faster-growing plants that take up nutrients from the soil much quicker and produce 82% more fruit by weight http://www.gizmag.com/nanoparticles-boost-growth-of-tomatoes/40285/. The titanium dioxide increases chlorophyll content to boost photosynthesis while the zinc improves the function of key enzymes; the tomatoes also produced between 80% and 113% more lycopene. The level of nanoparticles was below official limits and lower than that in normal fertilisers. Additional nanoparticles are being explored as well as optimising the levels of nanoparticles needed. 

9. Desalination via Shock Electrodialysis
Shock electrodialysis is a new desalination process that involves flowing salty water through a porous material while electrodes on either side of the pipe of porous material allow a current to flow through the flow that, beyond a certain level, induces a shock wave that sharply divides the flowing stream into fresh and salty regions that can be easily separated to isolate the fresh water http://news.mit.edu/2015/shockwave-process-desalination-water-1112. While a practical device has been demonstrated, scaling up the process will be important to find applications where it is competitive with other methods. 

10. Rapid 3D-Printable Robots
Disney research and collaborators have developed an interactive 3D computer-aided-design system that allows novice users to quickly create 3D-printable robotic creatures http://www.disneyresearch.com/publication/interactive-design-of-3d-printable-robotic-creatures/. Not only are robot designs, leg count, and degrees of freedom quickly customisable by the use via the system, but movement, gait, and fine aspects of motor control can be intuitively modified as desired and when happy with the model it can be printed, hooked up to off-the-shelf servo motors, and run in a manner that closely mimics the simulation.

Resharing this #Inspirobite

The Optimist Creed

Promise Yourself

To be so strong that nothing can disturb your peace of mind.

To talk health, happiness, and prosperity to every person you meet.

To make all your friends feel that there is something in them.

To look at the sunny side of everything, and make your optimism come true.

To think only of the best, to work only for the best and expect only the best.

To be just as enthusiastic about the success of others as you are about your own.

To forget the mistakes of the past and press on to the greater achievements of the future.

To wear a cheerful countenance at all times and give every living creature you meet a smile.

To give so much time for the improvement of yourself that you have no time to criticize others.

To be too large for worry, too noble for anger, too strong for fear and too happy to permit the presence of trouble.

- Optimist International
