Germs add ripples to make ‘groovy’ graphene

Posted by in categories: biotech/medical, computing, engineering, nanotechnology, particle physics

Graphene, a two-dimensional wonder-material composed of a single layer of carbon atoms linked in a hexagonal chicken-wire pattern, has attracted intense interest for its phenomenal ability to conduct electricity. Now University of Illinois at Chicago researchers have used rod-shaped bacteria — precisely aligned in an electric field, then vacuum-shrunk under a graphene sheet — to introduce nanoscale ripples in the material, causing it to conduct electrons differently in perpendicular directions.

The resulting material, sort of a graphene nano-corduroy, can be applied to a silicon chip and may add to graphene’s almost limitless potential in electronics and nanotechnology. The finding is reported in the journal ACS Nano.

“The current across the graphene wrinkles is less than the current along them,” says Vikas Berry, associate professor and interim head of chemical engineering at UIC, who led the research.

Atomic bits despite zero-point energy? Jülich scientists explore novel ways of developing stable nanomagnets

Posted by in categories: computing, mobile phones, nanotechnology, particle physics, quantum physics

Stable nanomagnets that ultimately improves data storage on the smallest of devices.


Abstract: So-called “zero-point energy” is a term familiar to some cinema lovers or series fans; in the fictional world of animated films such as “The Incredibles” or the TV series “Stargate Atlantis”, it denotes a powerful and virtually inexhaustible energy source. Whether it could ever be used as such is arguable. Scientists at Jülich have now found out that it plays an important role in the stability of nanomagnets. These are of great technical interest for the magnetic storage of data, but so far have never been sufficiently stable. Researchers are now pointing the way to making it possible to produce nanomagnets with low zero-point energy and thus a higher degree of stability (Nano Letters, DOI: 10.1021/acs.nanolett.6b01344).

Since the 1970s, the number of components in computer chips has doubled every one to two years, their size diminishing. This development has made the production of small, powerful computers such as smart phones possible for the first time. In the meantime, many components are only about as big as a virus and the miniaturization process has slowed down. This is because below approximately a nanometre, a billionth of a meter in size, quantum effects come into play. They make it harder, for example, to stabilise magnetic moments. Researchers worldwide are looking for suitable materials for magnetically stable nanomagnets so that data can be stored safely in the smallest of spaces.

42,300 Transistor Megaprocessor Is Complete

Posted by in category: computing

Hmmm; okay.


As it turns out, the answer is not 42, it’s 42.3 — thousand. That’s how many discrete transistors spread across the 30 m2 room housing this massive computation machine. [James Newman’s] Megaprocessor, a seriously enlarged version of a microprocessor, is a project we’ve been following with awe as it took shape over the last couple of years.

Google Tests Post-Quantum Crypto

Posted by in categories: computing, internet, quantum physics, security

Good article overall; and yes QC is still evolving. However, to state Quantum networking is in its infancy is a wrong & misleading comment. Since 2009, Quantum Internet has been in beta at Los Alamos Labs. And, researchers will tell you that QC development can as far back as 1970s and the first official QC was introduced in 2009 when the first universal programmable quantum computer was introduced by University of Toronto’s Kim Luke.


Google has launched a two-year Chrome trial aimed at safeguarding the Internet against quantum computers, which security experts predict will shred all data.

Forget Iron Man: skintight suits are the future of robotic exoskeletons

Posted by in categories: biotech/medical, computing, cyborgs, robotics/AI

Children with a rare neurological disease were recently given the chance to walk for the first time thanks to a new robotic exoskeleton. These devices – which are essentially robotic suits that give artificial movement to a user’s limbs – are set to become an increasingly common way of helping people who’ve lost the use of their legs to walk. But while today’s exoskeletons are mostly clumsy, heavy devices, new technology could make them much easier and more natural to use by creating a robotic skin.

Exoskeletons have been in development since the 1960s. The first one was a bulky set of legs and claw-like gloves reminiscent of the superhero, Iron Man, designed to use hydraulic power to help industrial workers lift hundreds of kilogrammes of weight. It didn’t work, but since then other designs for both the upper and lower body have successfully been used to increase people’s strength, help teach them to use their limbs again, or even as a way to interact with computers using touch or “haptic” feedback.

Microsoft uses BBC Micro Bit and virtual reality to prepare autistic kids for jobs

Posted by in categories: computing, education, employment, neuroscience, virtual reality

Good work by Microsoft.


Autism is a spectrum disorder, meaning not all people that meet the classification have identical behaviors. Some of these folks are very functional, while others may struggle more to socialize, or not be able to hold jobs.
