Researchers show how to make non-magnetic materials magnetic

Posted by in categories: computing, particle physics

O,.o well then anything could be a computer even a mushroom or a rock :3.

A complex process can modify non-magnetic oxide materials in such a way to make them magnetic. The basis for this new phenomenon is controlled layer-by-layer growth of each material. An international research team with researchers from Martin Luther University Halle-Wittenberg (MLU) reported on their unexpected findings in the journal Nature Communications.

In solid-state physics, oxide layers only a few nanometres thick are known to form a so-called two-dimensional electron gas. These thin layers, separated from one another, are transparent and electrically insulating materials. However, when one grows on top of the other, a conductive area forms under certain conditions at the interface, which has a metallic shine. “Normally this system remains non-magnetic,” says Professor Ingrid Mertig from the Institute of Physics at MLU. The research team has succeeded in controlling conditions during growth so that vacancies are created in the atomic layers near the interface. These are later filled in by other atoms from adjoining atomic layers.

The Army’s next robot will know when you’re talking trash to it — and know when to talk back

Posted by in categories: military, robotics/AI

The Army is developing a system to allow autonomous ground robots to communicate with soldiers through natural conversations — and, in time, learn to respond to soldier instructions no matter how informal or potentially crass they may be.

Researchers from the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory, working in collaboration with the University of Southern California’s Institute for Creative Technologies, have developed a new capability that allows conversational dialogue between soldiers and autonomous systems.

While new cases of the novel Coronavirus are still popping up in China, the country is facing yet another potentially contagious viral infection. This time, it’s jumping from ticks to people.

According to a report by Global Times, cases of the Severe Fever with Thrombocytopenia Syndrome (SFTS) virus first appeared in April and since then more than 37 people in East China’s Jiangsu Province have contracted with the virus and 23 people were found infected in East China’s Anhui Province. As of 6 August, around seven people have died from the infection.

Episode 10 — The Case for Mars Polar Science

Posted by in categories: climatology, science, space travel

Great interview with planetary scientist Isaac Smith, an expert on Mars polar science at York University in Toronto. Well worth a listen.

Three spacecraft are currently en route to Mars, but none will visit the poles. Yet Mars’ poles drive much of the Martian climate. And their understanding is key to deciphering what might have been happening on the Red planet some 3.5 billion years ago when it had lakes, deltas, rivers, and perhaps even transient oceans. I’m very pleased to welcome planetary scientist Isaac B. Smith of York University in Toronto — an expert on Mars polar science and exploration — to discuss the need for a Martian polar lander as well as a broader look at Mars science.

The newly discovered weird link between REM sleep and eating patterns

Posted by in categories: food, neuroscience

An intriguing new study, from a team of Swiss researchers, has revealed neural activity during REM sleep in a particular region of the brain known to affect appetite and feeding behaviors significantly influences waking eating patterns.

Despite a hefty volume of robust study, REM sleep is still a mysterious and unique sleep phase. Named after the rapid eye movements that occur in all mammals during this sleep phase, it has also been referred to as paradoxical sleep, due to the strange similarity in brain activity between waking states and REM sleep.

The new research homed in on a brain region called the lateral hypothalamus. This tiny brain region, found in all mammals, is known to play a fundamental role in food intake, compulsive behavior, and a number of other physiological processes.
