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.
It’s one atom thick, stronger than steel, harder than diamond and one of the most conductive materials on earth.
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.

When the idea of a medical transplant is brought up, most people’s thoughts are usually drawn to procedures such as blood transfusions or organ replacements. But, oftentimes, we forget the importance of our bone structure, as well as the 2 million painful bone transplants that take place every year around world. Previously stuck in a Medieval-like operation method, surgeons had little option but to replace their patients’ bones with the bones of animals or human cadavers, and even this procedure can oftentimes led to complications due to the body’s rejection of the foreign replacement. But 3D bioprinting has been a major influence in changing the entire nature of this traditional surgical procedure, new methods of creating bone grafts have been developed by researchers around the world from Montana State University to Tokyo. 3D printing has become a recent revelation in skeletal reconstruction surgery, with 3D printed synthetic implants and even harvested stem cell materials proving to be a much safer and efficient surgical alternative.
Researchers at the school of physics and astronomy at Tel Aviv University have created a track around which a superconductor (a material that is extremely efficient at transmitting electricity) can float, thanks to the phenomenon of “quantum levitation “.
This levitation effect is explained by the Meissner effect, which describes how, when a material makes the transition from its normal to its superconducting state, it actively excludes magnetic fields from its interior, leaving only a thin layer on its surface.
When a material is in its superconducting state — which involves very low temperatures — it is strongly diamagnetic. This means that when a magnetic field is externally applied, it will create an equally opposing magnetic field, locking it in place.
A material called yttrium barium copper oxide can be turned into a superconductor by exposure to liquid nitrogen — which makes it one of the highest-temperature superconductors.
Levitation isn’t just for Houdini anymore. Could this cool new tech lead to floating alternatives to traditional gas powered vehicles? Interesting times ahead!
Another step forward for Quantum — The Quantum Current. US Dept. of Energy has a new method to generate very low-resistance electric (Quantum) current which will improve our methods for energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity—the ability of some materials (zirconium pentatelluride) to carry current with no energy loss.
We all have “Quantum Spark”.
For centuries philosophers have grappled with the question of what makes life, and thanks to the science of quantum mechanics we might just have the answer, writes Johnjoe McFadden.
What is life? Why is the stuff of life — flesh — so different from inanimate material? Does life obey the same laws as the inanimate world? And what happens when we die?
These questions have been pondered by philosophers, scientists and the rest of us for centuries. For most of human history the answer was that life was special. It was animated by some kind of spirit, soul or qui, a vital spark that was absent from the non-living. But, by the end of the 19th century, this theory, known as vitalism, was pretty much discredited by the discovery that living organisms are made from the same chemicals as the inanimate world — atoms and molecules of carbon, nitrogen, oxygen and so on.
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.
At Singularity University, space is one of our Global Grand Challenges (GGCs). The GGCs are defined as billion-person problems. They include, for example, water, food, and energy and serve as targets for the innovation and technologies that can make the world a better place.
You might be thinking: We have enough challenges here on Earth—why include space?
We depend on space for telecommunications, conduct key scientific research there, and hope to someday find answers to existential questions like, “Are we alone in the universe?”. More practically, raw materials are abundant beyond Earth, and human exploration and colonization of the Solar System may be a little like buying a species-wide insurance policy against disaster.
Bioprinting companies can be successful at start-up investment conferences, although they are sometimes outshone by more immediately accessible products. Bioprinters have the potential to drastically change life expectancy and quality in the long term, but can “only” help out with scientific research in the short term and that, often, is not exciting enough for start-up awards.
That was not the case at the recent SVOD (Silicon Valley Open Doors) Europe, an investment conference that began in 2005 and went global in 2015. The event then came to Europe for the first time in an effort to connect the Eastern European tech community with more established ecosystems. This year, the event took place in Ireland and “local” startupper Jemma Redmond took home the top prize with the Ourobotics 10 material 3D bioprinter.
I have been following Jemma and her team’s progress, from the pre-conference preparation all the way up to her presentation, via Facebook feed and other updates. The event took place at Google’s Dublin HQ and the winning team received, among other things, $5,000 in Google Adwords credits. Clearly happy about this success, Jemma told me they faced off against 25 other teams.
