Chemists discover the structure of a key coronavirus protein

Chemists have determined the molecular structure of a protein found in the SARS-CoV-2 virus. This protein forms a cation-selective channel and plays a key role in the virus's ability to replicate itself. If researchers could devise ways to block this channel, they may be able to reduce the pathogenicity of the virus and interfere with viral replication.

Thermodynamics of off-equilibrium systems

Arguably, almost all truly intriguing systems are ones that are far away from equilibrium -- such as stars, planetary atmospheres, and even digital circuits. But, until now, systems far from thermal equilibrium couldn't be analyzed with conventional thermodynamics and statistical physics.

Silicone surface mimics topology, wettability of a real human tongue

The tongue helps people taste food, but structures on its surface also help them sense textures -- something that's also very important when savoring a meal. Now, researchers have made a 3D silicone surface that, for the first time, closely mimics the surface features of the human tongue. The material could help food scientists study mechanical interactions of foods, liquids and medicines with the organ.

Sensor for smart textiles survives washing machine, cars and hammers

If the smart textiles of the future are going to survive all that we throw at them, their components are going to need to be resilient. Now, researchers have developed an ultra-sensitive, seriously resilient strain sensor that can be embedded in textiles and soft robotic systems. It could be used in everything from virtual reality simulations and sportswear to clinical diagnostics for neurodegenerative diseases like Parkinson's Disease.

Turning heat into electric power with efficient organic thermoelectric material

Thermoelectric materials can turn a temperature difference into electricity. Organic thermoelectric materials could be used to power wearable electronics or sensors; however, the power output is still very low. An international team has now produced an n-type organic semiconductor with superior properties that brings these applications a big step closer.

Weighing space dust with radar

It is thought that over 1,000 kilograms of so-called interplanetary dust falls to Earth every day. This dust is essentially an untold number of small faint meteors, discarded remnants of asteroids and comets that pass by the Earth. Two ways to study faint meteors are radar and optical observations, each with advantages and limitations. Astronomers have combined specific observations with both methods, and can now use radar to make the kinds of observations that previously only optical telescopes could make.

New research on imposter stars may improve astronomical data

Quick flashes of light reflecting from satellites and debris in Earth's orbit are extremely common, according to new findings that may improve the accuracy of astronomical data. For the first time, astronomers report the flashes, which are often mistaken for stars, occur more than 1,000 times an hour across the sky.
