This automatic shoe cover machine will play a role in some places during the coronavirus outbreak.

A combination of cold weather and just the right amount of wave motion has caused strange frozen spheres to cover a Finnish beach.

A desirable option would be to use CRISPR gene editing to essentially cut out the unwanted gene. There are, however, many challenges ahead.

If you want to remove an undesirable gene from a population, you have a couple theoretical options — one that most people might find unthinkable, and one that lies outside our current scientific abilities.

Scientists say they have discovered the first evidence of a “significant” mutation of the coronavirus — raising concerns that strides made toward a vaccine so far could become “futile,” according to a new study.

The researchers, who isolated a strain of the virus from a sample collected in India in January, said the mutation appeared to make the bug less able to bind to a receptor on human cells called ACE2, an enzyme found in the lungs.

The discovery of this mutation “raises the alarm that the ongoing vaccine development may become futile in future epidemic if more mutations were identified,” the researchers said, according to Newsweek. The study, which was published on biorxiv.org on Saturday, has not yet been peer-reviewed.

Artificial intelligence and brain scanning technology like fMRI may make it possible for humans to understand what pet animals and livestock are thinking.

:oooo.

Metasurfaces are artificial materials designed at the nanoscale, which can control the scattering of light with exceptionally high precision. Over the past decade or so, these materials have been used to create a variety of technological tools ranging from sensors to lenses and imaging techniques.

A research team led by Mikhail Lukin at Harvard University has recently proposed a new type of metasurface that can control both the spatiotemporal and quantum properties of transmitted and reflected light. In a paper published in Nature Physics, the team showed that realizing a quantum metasurface is possible and could be achieved by entangling the macroscopic response of thin atom arrays to light.
