After ALS struck, he became the world’s most advanced cyborg

Posted by in categories: biological, cyborgs, robotics/AI

At this point, Scott-Morgan is almost completely “locked-in,” unable to move except for his eyes and a few facial muscles. His sense of smell and taste are gone, and he can’t breathe on his own, but his brilliant mind is fully intact.

Scott-Morgan now relies on a synthetic version of his biological voice and has had his face scanned to produce a 3D animated avatar, which he wears on a screen on his chest when speaking publicly. After a series of operations to extend his life, including a total laryngectomy, he uses technologies like GPT-2, OpenAI’s generative deep-learning model for text, pushing the boundaries of what it means to be human.

Smallest transistor worldwide switches current with a single atom in solid electrolyte

Circa 2018


Digitization results in a high energy consumption. In industrialized countries, information technology presently has a share of more than 10% in total power consumption. The transistor is the central element of digital data processing in computing centers, PCs, smartphones, or in embedded systems for many applications from the washing machine to the airplane. A commercially available low-cost USB memory stick already contains several billion . In the future, the single-atom transistor developed by Professor Thomas Schimmel and his team at the Institute of Applied Physics (APH) of KIT might considerably enhance energy efficiency in . “This element enables switching energies smaller than those of conventional silicon technologies by a factor of 10,000,” says physicist and nanotechnology expert Schimmel, who conducts research at the APH, the Institute of Nanotechnology (INT), and the Material Research Center for Energy Systems (MZE) of KIT. Earlier this year, Professor Schimmel, who is considered the pioneer of single-atom electronics, was appointed Co-Director of the Center for Single-Atom Electronics and Photonics established jointly by KIT and ETH Zurich.

In Advanced Materials, the KIT researchers present the transistor that reaches the limits of miniaturization. The scientists produced two minute metallic contacts. Between them, there is a gap as wide as a single metal atom. “By an electric control pulse, we position a single silver atom into this gap and close the circuit,” Professor Thomas Schimmel explains. “When the silver atom is removed again, the circuit is interrupted.” The world’s smallest transistor switches current through the controlled reversible movement of a single atom. Contrary to conventional quantum electronics components, the single-atom transistor does not only work at extremely low temperatures near absolute zero, i.e.-273°C, but already at room temperature. This is a big advantage for future applications.

HIV can hide inside human cells for years. Can CRISPR cut it out?

Posted by in category: biotech/medical

Using CRISPR to stop the replication of SIV, a primate virus closely related to HIV, researchers may have taken a step to wiping the virus out in the body.

Waymo plans fleet of self-driving, all-electric robotaxis with Chinese automaker Geely

Posted by in categories: robotics/AI, transportation

Alphabet’s self-driving car company Waymo is partnering with Chinese automaker Geely to create a fleet of all-electric, self-driving robotaxis.

The cars will be designed in Sweden (where Geely owns Swedish carmaker Volvo) and will be adapted from Geely’s all-electric five-door Zeekr. Waymo will then outfit the cars with the hardware and software necessary for autonomous driving. Waymo said in a blog post that it plans to deploy the vehicles in the US as part of its existing fleet of self-driving robotaxis some time “in the years to come.”

Concept images of finished vehicle shared by Waymo show a car that is designed specifically for autonomous ride-hailing trips. It has a flat floor, low step-in height, and B-pillarless design for easy entry and exit, as well as sliding doors, reclining seats, and plenty of headroom. Waymo says future models will have an interior without steering wheel or pedals — just a screen (presumably to let riders check on the progress of their journey).

Personalized skin cancer vaccine is made from tumor cells

Posted by in category: biotech/medical

This year, an estimated 100,000 people in the U.S. will be diagnosed with melanoma, a rare but aggressive form of skin cancer — and even if they beat it, they’ll be at a high risk of developing melanoma again.

That might not always be the case, though, as a personalized skin cancer vaccine developed from patients’ own tumor cells has shown promise in a very small trial, involving eight melanoma survivors.

“We found evidence of everything we look for in a strong, sustained immune response,” study co-leader Patrick A. Ott said in a press release.

“Fundamental Discovery” Used To Turn Nanotube Into Tiny Transistor — 25,000x Smaller Than Width of a Human Hair

Posted by in categories: computing, nanotechnology

An international team of researchers has used a unique tool inserted into an electron microscope to create a transistor that’s 25,000 times smaller than the width of a human hair.

The research, published in the journal Science, involves researchers from Japan, China, Russia, and Australia who have worked on the project that began five years ago.

QUT Center for Materials Science co-director Professor Dmitri Golberg, who led the research project, said the result was a “very interesting fundamental discovery” which could lead a way for the future development of tiny transistors for future generations of advanced computing devices.

Tuning a magnetic fluid with an electric field creates controllable dissipative patterns

Posted by in categories: chemistry, nanotechnology

Researchers at Aalto University have shown that a nanoparticle suspension can serve as a simple model for studying the formation of patterns and structures in more complicated non-equilibrium systems, such as living cells. The new system will not only be a valuable tool for studying patterning processes but also has a wide range of potential technological applications.

The mixture consists of an oily liquid carrying of iron oxide, which become magnetized in a magnetic field. Under the right conditions, applying a voltage across this ferrofluid causes the nanoparticles to migrate, forming a concentration gradient in the mixture. For this to work, the ferrofluid has to also include docusate, a waxy chemical that can carry charge through the fluid.

The researchers discovered that the presence of docusate and a voltage across the ferrofluid resulted in a separation of electric charges, with the iron oxide nanoparticles becoming negatively charged. “We didn’t expect that at all,” says Carlo Rigoni, a postdoctoral researcher at Aalto. “We still don’t know why it happens. In fact, we don’t even know whether the charges already get split when the docusate is added or if it happens as soon as voltage is turned on.”
