Deep learning hardware, DNA origami pores, Insect drone vision, Compressible torsional materials, Choreographic crystals, 3D printing metals, Implantable sensors, 3D NAND chips, Bone thymus rejuvenation, deep learning software.

1. EIE Chip Accelerates Deep Learning
New software and hardware architecture has been developed into a chip called EIE that significantly boosts the performance of deep neural network applications http://www.nextplatform.com/2015/12/08/emergent-chip-vastly-accelerates-deep-neural-networks/. EIE basically maximises the role of SRAM in processing the inference side of neural networks and uses newly developed “deep compression” to pare these networks down to their most essential components while retaining accuracy to allow ultra-fast, ultra-efficient processing. The chip performs inference operations between 13x and 189x faster compared to benchmarks, while delivering energy efficiency between 3,000x and 24,000x better compared to benchmarks. Interesting questions arise relating to the nature of neural networks and the drastic pruning you can inflict. How long until these chips start being integrated into servers and mobile platforms?

2. DNA Origami Membrane Pores
Self assembling DNA origami techniques have been used to create synthetic molecular membrane pores in biological membranes that can be controllably opened and closed http://phys.org/news/2016-01-dna-blocks-pave-drug-delivery.html. The pores were anchored to the membranes of vesicles and the addition of different complementary strands of DNA was shown to open and close the pore to allow the passage of certain molecules through the 2nm channel, or at least alter their rate of passage by 140-fold. In related news DNA origami structures are being used to functionalise gold nanoparticles and form well-ordered arrays and novel materials out of the particles https://www.mcgill.ca/newsroom/channels/news/printing-press-nanoparticles-257609.

3. Insect Drones & Catcher Drones
In a simple yet effective development, drones operating with insect-inspired vision strategies that become unstable in flight at a specific distance from a landing zone, can utilise this very instability to estimate distance, correct their flight, and execute far smoother and more precise landings http://www.tudelft.nl/en/current/latest-news/article/detail/door-nieuwe-theorie-kunnen-drones-afstanden-zien-met-een-oog/. It also allows the drone to shed other sensors and weight. In other drone news a new anti-drone system employs remote or autonomous drones to shoot a net to capture rogue drones in mid-flight http://www.mtu.edu/news/stories/2016/january/drone-catcher-robotic-falcon-can-capture-retrieve-renegade-drones.html and 100 drones can now be coordinated together in flight http://www.gizmag.com/100-drones-guinness-world-record/41328/.

4. Torsional Materials and Extreme Compressibility
New materials designed with coordination geometries, where subunits in the bulk material form a coordinated framework and are free to rotate, move, or deform independently, have been developed that exhibit properties of extreme compressibility http://phys.org/news/2016-01-atomic-gears-torsion-springs-contribute-extreme.html. Such materials have negative thermal expansion coefficients, shrinking in volume when heated for example, and under pressure deform and compress to a larger extent than any other crystalline material. In these materials compression doesn’t induce the normal shortening of bonds, but rather the structural deformation of subunits that move and rotate to bring nearby subunits closer together.

5. Crystal with Time-Dependent Symmetry
A new type of crystal has been described that possesses symmetry not in the way its atoms are structured but rather in the way it’s particles move in time http://gizmodo.com/physicists-discover-a-new-kind-of-crystal-inspired-by-s-1751911893. It is interesting that the discovery was inspired by satellite orbits as gravity wave detectors because the movement does remind me of quadrupole motion. This is a type of dynamic symmetry, and these hypothetical materials are now known as choreographic crystals; the work also involved some clever mathematics to identify all possible such arrangements above the tetrahedron analogue discovered here. As these are currently confined to theory it remains to be seen whether such materials can be discovered or fabricated - and what their properties might be, for example new metamaterials are able to boost MRI sensitivity by 50% http://phys.org/news/2016-01-metamaterials-boost-sensitivity-mri-machines.html.

6. Improved 3D Printed Metals
Related to last week’s innovation for much improved 3D printed ceramics, this week we have much improved 3D printed metals and metal alloys using liquid inks and common furnaces http://www.mccormick.northwestern.edu/news/articles/2016/01/a-new-way-to-print-3-d-metals-and-alloys.html. The liquid inks contain metal powders, solvents, and elastomers, are printed normally and then sintered in furnace to make the powder fuse; prior to sintering the printed object can be bent and further altered to achieve different structures, and the technique allows safer metal oxides to be printed then turned into their base metals with the addition of hydrogen.

7. Implantable & Wearable Sensors
A couple of fascinating items from the CES show. First, Lumee is an implantable grain-of-rice-sized device and sensing platform made of hydrogel that sits below the skin that doesn’t trigger scar tissue or an immune response and so can remain for very long periods; the prototype contains a dye that measures oxygen levels and which can be interrogated by shining light through the skin http://spectrum.ieee.org/view-from-the-valley/biomedical/devices/move-over-wearables-make-way-for-implantables - a fantasitc platform with a huge range of sensing and diagnostic applications and these new liquid crystal hydrogels might offer additional customisation and control http://phys.org/news/2016-01-polymer-medical-solutions.html. Second, a tiny flexible sticky sensor patch works on thermoelectric principles, harvesting energy from the temperature gradient between your skin and the air, the prototype for which monitors your hydration levels and sends this information to your smartphone http://spectrum.ieee.org/tech-talk/biomedical/devices/power-harvesting-sensor-patch-uses-your-body-as-a-battery - great platform with a larger number of applications.

8. Commercial 3D NAND Chips
Micron claims their new 3D NAND memory chips get Flash-based memory back on Moore’s Law scaling curve http://www.eetimes.com/document.asp?doc_id=1328652. Their first generation 3D NAND chip is a stack 32 layers deep and being offered in versions with 32 and 48 Gigabytes each; the future roadmap includes 2 Terabyte 3D NAND packages enabling solid state drives with a capacity of 32TB. They’ve also designed and released new chips in a partnership with Intel that have a 3D cross-bar architecture (3D XPoint) sandwiching a material to create arrays of resistive RAMs and enabling mass commercial rollout for memristors.

9. Bone & Thymus Rejuvenation Approaches
A new microRNA delivery technology utilises polymer spheres to protect the microRNA cargo and get inside cells and it can slowly release the payload over the course of a month if needed; in the proof of concept the spheres targeted cells at wound sites in bone, delivering microRNAs that instructed the cells to ramp up bone healing and bone building processes http://ns.umich.edu/new/releases/23403-nano-shells-deliver-molecules-that-tell-bone-to-repair-itself. Boosting levels of metabolic hormone FGF21 in the thymus of old mice protects the organ from age-related degeneration, increasing T-cell production, maintaining an active immune system and extending lifespan by 40%; looking forward to human tests http://news.yale.edu/2016/01/11/life-extending-hormone-bolsters-body-s-immune-function.

10. Microsoft’s 152 Layer Neural Network
Microsoft Research won the ImageNet image recognition contest with a powerful new machine learning architecture called a deep residual network that is more complex than previous deep learning architectures and spans 152 layers http://www.wired.com/2016/01/microsoft-neural-net-shows-deep-learning-can-get-way-deeper/. The new architecture can examine many more features of a data set (images in this case) and circumvents the problem of signal dilution that has plagued other attempts by being able to quickly skip layers that it doesn’t need. Closing the feedback-loop of developing these applications the team also created a system that helps build these networks as needed. The potential here is significant.

Space Glass

Japanese glass artist Satoshi Tomizu manages to create wondrous cosmic scenes by encasing the universe in orbs of glass that are no larger than the human eye. His pendants are known as Space Glass. Each of them is unique and has breathtaking detail. It’s like a mesmerizing microcosm that can be held in the palm of your hand. These miniature spheres are made of opals, specks of real gold, and swirls of colored glass that spin and burst into constellations of the universe

Tomizu captures these spheres as a close up, reminiscent of the Men In Black film scene of the jewelry piece worn on the cat's collar. Each bauble is blown with a durable glass loop allowing one to wear their personal space-scape around their neck if they wish.

His work has earned him an Atelier Nova Design Award and has also been exhibited in Handmade in Japan Festival.
