SciTech #ScienceSunday Digest - 35/2015.
Permalink here: http://www.scitechdigest.net/2015/08/assembling-molecular-electronics.html

Assembling molecular electronics, Neuronal polymer networks, Electroplating manufacturing, Handheld medical diagnostics, Nanomagnet computers, Deep learning FPGAs, Confined electromagnetism theory, Optogenetic feedback, CRISPR delivery, Solid state batteries. 

1. Self-Assembled Molecular Electronic Components
Stacks of certain self-assembled aromatic molecules form molecular cages that take on different electronic properties depending on the contents of the cage: empty cages behave like a resistor, with two identical molecular pairs it acts like a wire, and with two different molecular pairs it acts like a diode http://phys.org/news/2015-08-self-assembled-aromatic-molecular-stacks-modular.html. These self-assembled subunits could then be connected to form basic circuits, as an initial proof-of-concept towards using the platform to create self-assembled molecular electronics with modular components. 

2. Custom Polymer Networks from Biological Tools
By taking kinesin motor proteins (that usually carry cargo along microtubules in the cell) and attaching them upside down on a surface, sprinkling this surface with polymer microspheres and protein microtubules, researchers can create highly-branched polymer neural structures https://share.sandia.gov/news/resources/news_releases/bio_tools/#.Vd0yn1WUfVk. The kinesin proteins on the surface naturally transport the microtubules, which encounter the polymer spheres, and draw off strands of polymer nanotubes and before long very complex neural structures form. The group hope to wire different networks together, and with both light and electricity being transported by the resulting substrate they hope neural interfaces might be a possible future application. 

3. Additive Manufacturing via Electroplating
Modumetal’s novel metal manufacturing technology is starting to see broader use http://fortune.com/2015/08/25/grow-metal-like-a-tree/. Modumetal’s process essentially uses electrochemistry and electroplating with finer control at the microscale to better manage the conditions under which electroplating occurs, allowing them to grow metal on surfaces layer by layer and alter the characteristics of these metal laminates. Ultimately the laminated metal alloys produced by the company are stronger and more corrosion resistant and have already been used by a variety of customers in different industries. 

4. Handheld Standard Medical Tests
A new handheld, battery powered, 3D printed device incorporates a mouthpiece and thumb pad with sensors to quickly test a person’s blood pressure, breathing rate, blood oxygen, heart rate, and temperature readings http://www.hopkinsmedicine.org/news/media/releases/mouthlab_patients_vital_signs_are_just_a_breath_away, and might be expanded to read a range of other measures in future. The performance of the device was benchmarked against standard testing devices and matched the output of these more expensive units to within small margins of error. A wireless connection transfers data to a computer or smartphone. This also gives some nice ideas for Project Ara modules. 

5. Computation with Nanomagnets
Here is a nice review article on the efforts and progress to develop computer chips based on a nanomagnet architecture in which not just memory but processing and computation is performed by suitably coordinated flips of tiny magnetic domains http://spectrum.ieee.org/semiconductors/devices/building-ultraenergyefficient-computers-out-of-tiny-bar-magnets. While nanomagnetic computation will never be as fast as conventional silicon (and other materials) transistors, it promises to be 10 - 100 times as energy efficient and of course is able to hold its state of computation even after the power is switched off. Switches and wires are built out of nanomagnets arrayed on a surface and in which the controlled flip of one causes its neighbour to flip and so on like a line of dominoes. 

6. From GPUs to FPGAs for Deep Learning
Microsoft’s research in deep learning seeks to overcome some of the shortcomings and costs of the ubiquitous use of GPUs in deep learning applications http://www.technologyreview.com/news/540851/microsoft-says-programmable-chips-will-make-ai-software-smarter/. Work to date with some of the most advanced FPGAs available indicates that significant performance improvements for deep learning neural networks are possible and that the use of FPGAs would allow much larger neural networks to be utilised. The main drawback is the additional work required to program the FPGAs for the particular task to be done. 

7. Theory for Confined Electromagnetism
A new theory seeks to demonstrate how electromagnetic energy can be confined without the source radiating http://nextbigfuture.com/2015/08/theory-explaining-electromagnetic.html. The result depends on a charged source (such as an electron) exhibiting a toroidal dipole moment associated with a circulating magnetic field that has a similar mode to the sources conventional electric field distribution; these can destructively interfere to cancel the distant field to make the source appear confined. Experiments on nanodisks seem to provide some validation for the theory to produce these “anapole” structures. It’ll be interesting to see if this holds up - new natural electromagnetic phenomena like this could have a wide range of applications. 

8. Optogenetic Feedback Device
An open source technology platform called optoclamp has been developed that seeks to provide a convenient feedback loop for optogenetics applications http://medicalxpress.com/news/2015-08-loop-optogenetics.html. Basically the device measures neuronal responses to optical signals it sends to optogenetically activated neurons, and quickly varies the light input to maintain the desired firing rate from seconds to days. This is believed to be the first device to offer closed-loop control for optical stimulation, and should lead to more powerful optogenetics applications, experiments, and neurological discoveries. 

9. Self-Assembled CRISPR Delivery System
A new CRISPR delivery system involves self-assembled DNA structures and polymers that bind and encapsulate both the specific CRISPR guide-RNA and the Cas-9 protein; when the structure comes into contact with a cell it is engulfed into an endosome that is subsequently broken down by the charged polymer, setting the CRISPR system free to perform its gene editing work if and when it gets into the nucleus https://news.ncsu.edu/2015/08/gu-beisel-clews-2015/. In a proof-of-concept the system was able to successfully edit the genetics of a third of cancer cells it was exposed to. Having an alternative delivery system to the viruses that are typically used for such delivery, or other conventional techniques should be a bonus in many situations. 

10. MIT & Samsung’s Solid State Batteries
Work by MIT & Samsung has developed new solid-state electrolytes for lithium-ion batteries that seek to boost battery power, lifetime, and safety https://news.mit.edu/2015/solid-state-rechargeable-batteries-safer-longer-lasting-0817. The demonstration batteries produced provided a 20% - 30% improvement in power density and are unaffected by extremely low temperatures that degrade the performance of batteries with liquid electrolytes. The use of solid-state electrolytes is a bit of a game-changer and should ultimately lead to more research and better material designs.

Sad to hear of the passing of Oliver Sacks. He shared his abundant curiosity of life with the world and we are better for it. In his own words, from his final op-ed [1]: "And now, weak, short of breath, my once-firm muscles melted away by cancer, I find my thoughts, increasingly, not on the supernatural or spiritual, but on what is meant by living a good and worthwhile life — achieving a sense of peace within oneself. I find my thoughts drifting to the Sabbath, the day of rest, the seventh day of the week, and perhaps the seventh day of one’s life as well, when one can feel that one’s work is done, and one may, in good conscience, rest."

[1] nytimes.com/2015/08/16/opinion/sunday/oliver-sacks-sabbath.html
Whether writing about his patients, his love of chemistry or the power of music, Dr. Sacks leapfrogged among disciplines, shedding light on the connections between science and art.

I'm looking most forward to Now on Tap [1] and Permissions Management can't get here soon enough.

Via +Derek Ross

Some people believe that Android M doesn’t deserve the title of Android 6, mainly because it isn’t as big of an overhaul as previous Android 1.x releases have been or because it doesn’t accompany the visual changes we’ve seen on previous 1.x releases.

While on some level this is true, going over the long list of improvements does really put into perspective how big of an update M truly is.

Let’s go over all the features we will(or might) see on Android M:
• Now on Tap
• Permissions Management
• SD Cards can be “merged” with internal storage
• Android Pay
• Native fingerprint authentication
• Automatic app data backups
• App Links (you’re going to see less of those “what do you want to open this in?” prompts)
• Doze and App Standby
• Multi Window(currently hidden, uncertain future)
• Theming support(currently hidden, uncertain future)
• Dark theme(removed, uncertain future)
• Customisable Quick Toggles along with other UI tweaking
• Visual Voicemail Support
• Redesign of the Clock Widget and Music Identification Widget
• New “Memory” Section in Settings(it was there before, but hidden)
• Support for deleting screenshots directly through the notification centre after they’ve been taken
• Landscape mode available for the Google Now Launcher(feature will likely be backported to older versions of Android)
• New app and widget drawer with scroll bar support and vertical scrolling
• Built-In File Manager receives a bump in functionality
• Native tap to wake support
• Ability to disable “heads up” or “peeking” notifications
• Native 4K output support
• Stricter APK validation
• MIDI support
• USB Type C support
• New boot animation
• Introduction of a “voice interaction” API to allow better interaction with voice actions in apps
• Toggling battery saver by voice
• Ability to undo and redo text changes with bluetooth keyboard shortcuts
• Multi-selection to merge, delete or share has been added in the contacts application
• Faster text selection along with a floating toolbar for text actions
• Default apps UI
• Direct share can allow you directly share stuff with contacts through the share menu
• Much more granular app info
• Native bluetooth stylus support
• Split-screen keyboard
• Better do not disturb along with repeat caller exceptions
• Bluetooth scanning to improve location accuracy
• Native flashlight API
• Easier access to Multi volume controls(ringer, media, alarm)
• Smoother volume scrubbing (credits to Jason Efstathiou)

Putting all those features aside there are also a number of under-the-hood improvements that seem to have had a very positive impact on both performance and power usage.

I’m puzzled as to how someone could call this a “minor” update.

Visionary, futurist, student of human nature
Introduction
Life is good. We get to live at one of the most exciting times in history. We are using technology that is absolutely breathtaking. We have mobile devices in our pocket that are more powerful than the best computers just a few years ago and we communicate as a society like none in human history.

At the same time, we have seen only the beginning. I cannot wait for what is on the way. I cannot help but want to participate in this technological revolution.

About me, I am Chief Executive and Innovation Officer at Kitchen Cloud, a food management, healthy eating, and grocery shopping app.

My passion is thinking about ways to improve everyday life. Everything from having a smarter house, improving how we eat, produce and consume energy, to transportation systems (think smarter traffic signals). We can do better and I intend to help us get there.
