Liquid metal.
Abstract: Graphene is going to change the world — or so we’ve been told.
Since its discovery a decade ago, scientists and tech gurus have hailed graphene as the wonder material that could replace silicon in electronics, increase the efficiency of batteries, the durability and conductivity of touch screens and pave the way for cheap thermal electric energy, among many other things.
Making Nanowire Lasers
Feb. 11, 2016 — Scientists have found a simple new way to produce nanoscale wires that can serve as bright, stable and tunable lasers — an advance toward using light to transmit data.
Post-Human
Radically often it seems like something out of science fiction. But every day that passes we get closer to the technological singularity.

Very nice; another article on photonic crystal.
Scientists have created a crystal structure that boosts the interaction between tiny bursts of light and individual electrons, an advance that could be a significant step toward establishing quantum networks in the future.
Brand’s view and concerns about hacking driverless cars are valid. And, I do believe in time that government will eventually catch up in passing some laws that will make companies ensure that their technology is safe for consumer usage and are safe for the public. I just hope that the pendulum does swing too far to the other side of over regulation.
It is not easy to slot Brad Templeton. What do you make of a person who is not only the networks and computing chair at Singularity University in Silicon Valley but also a software architect, a director of the Foresight Nanotech Institute, board member of the cyberspace watchdog Electronic Frontier Foundation, the first person to have set up an Internet-based business, a futurist lecturer, hobby photographer, artist, as well as a consultant on Google’s driverless car design team?
In a phone interview from the US, Templeton, who will be in India this month as a key speaker during the SingularityU India Summit (to be held in association with INK, which hosts events like INKtalks—a platform for the exchange of cutting-edge ideas and inspiring stories), shared his views on driverless cars, the perceived threat from intelligent machines and censorship of the Internet. Edited excerpts:
Driverless cars are not hacker-proof and may find it difficult to navigate chaotic traffic. How are we addressing such issues?
It’s absolutely true that people are concerned about security of these cars, but it is wrong to presume that people in the media learnt about this before those who built the driverless car. The people who built the car are working to make the car secure. They won’t be able to do it perfectly, but they are going to get there. The Google team certainly has the most miles to its credit. Right now over 2 million km in automatic mode, driving around mostly in California. The chaotic driving in India is slower than some of the roads in Europe or North America. And it is actually easier to do slower and chaotic driving than faster. You get more time to stop, perceive the situation and make accurate moves. The real challenge is that in many chaotic driving situations, there are unwritten rules so you have to figure out how to sort of, play a game with the other cars. It may mean that some of the more chaotic places may have to clean up their act a bit if they want to have a technology like this.
Using laser to build nanostructures on metal; and watch water bounce off the nanostructure coating

What would be really cool is have a “Computer Screen in a Can”; take your polymer spray and instantly create a screen on a table, a window, suitcase, etc. with your “Computer Screen in a Can”; U Can! I can just imagine the infomercials. On a more serious note — NW Univ has developed a new Hybrid Polymer which is going to expand the capabilities of polymer into so many areas in medicine, to manufacturing, electronics, self reparing material & devices, etc.

A completely new hybrid polymer has been developed by Northwestern University (Evanston, IL) researchers.
“We have created a surprising new polymer with nano-sized compartments that can be removed and chemically regenerated multiple times,” said materials scientist Samuel Stupp, the senior author of the study and director of Northwestern’s Simpson Querrey Institute for BioNanotechnology. The study was published in the Jan. 29 issue of Science.
“Some of the nanoscale compartments contain rigid conventional polymers, but others contain the so- called supramolecular polymers, which can respond rapidly to stimuli, be delivered to the environment and then be easily regenerated again in the same locations. The supramolecular soft compartments could be animated to generate polymers with the functions we see in living things,” he said.
Interesting — I need to check in this one a little more.
Abstract: Researchers from Iran and Malaysia designed a nanostructure based on carbon nanotubes with antibacterial properties to be used in public places, specially hospitals and clinics.
Building building diamond lattices through DNA.
Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet elegant arrangement, as described in a paper published February 5, 2016, in Science, may open a path to new materials that take advantage of the optical and mechanical properties of this crystalline structure for applications such as optical transistors, color-changing materials, and lightweight yet tough materials.
“We solved a 25-year challenge in building diamond lattices in a rational way via self-assembly,” said Oleg Gang, a physicist who led this research at the Center for Functional Nanomaterials (CFN) at Brookhaven Lab in collaboration with scientists from Stony Brook University, Wesleyan University, and Nagoya University in Japan.
The scientists employed a technique developed by Gang that uses fabricated DNA as a building material to organize nanoparticles into 3D spatial arrangements. They used ropelike bundles of double-helix DNA to create rigid, three-dimensional frames, and added dangling bits of single-stranded DNA to bind particles coated with complementary DNA strands.
