Summary: Study reports SARS-CoV-2, the virus that causes COVID-19, was well suited to making the jump from animals to humans by shapeshifting as it gained the ability to infect human cells. The virus’s ability to infect humans occurred via exchanging gene fragments from a coronavirus that infected pangolins. The species-to-species transmission was a result of the ability of SARS-CoV-2 to bind to host cells through alterations to its genetic material.

A team of scientists studying the origin of SARS-CoV-2, the virus that has caused the COVID-19 pandemic, found that it was especially well-suited to jump from animals to humans by shapeshifting as it gained the ability to infect human cells.

Graphcore, the four-year-old startup based in Bristol, England, has a chip that takes the kinds of math that a neural network processes and splits them across 1,216 tiny computers, each of which does its work in parallel with its brethren. The company believes its chip makes new kinds of AI possible.

The decision to open up testing at Nellis comes as the National Spectrum Consortium wraps up solicitations for 5G testing at four other military bases.

Special Operations Command is launching a new program, Mission Command, that will present all the data needed for a mission in a single visualization.

SpaceX delivered two astronauts to the International Space Station for NASA on Sunday, following up a historic liftoff with an equally smooth docking in yet another first for Elon Musk’s company.

With test pilots Doug Hurley and Bob Behnken poised to take over manual control if necessary, the SpaceX Dragon capsule pulled up to the station and docked automatically, no assistance needed. The hatches swung open a few hours later, and the two Dragon riders floated into the orbiting lab and embraced the three station residents.

Physicists have created a wormhole device that can tunnel a magnetic field through space. It sounds like Star Trek, but we won’t be zapping humans across the universe anytime soon. Still, the breakthrough could revolutionize certain magnet-based technologies, including MRIs.

The kit has been granted approval under ‘emergency use’ provisions, and should help to ease testing backlogs in the country.

An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades — a feature that could possibly facilitate superconductivity at or near room temperature and pressure.

Such a superconducting material, carrying electricity without any energy loss due to resistance, would revolutionize energy efficiency in a broad range of consumer and industrial applications.

The scientists conducted neutron scattering experiments at the Department of Energy’s Oak Ridge National Laboratory on samples of zirconium vanadium hydride at atmospheric pressure and at temperatures from −450 degrees Fahrenheit (5 K) to as high as −10 degrees Fahrenheit (250 K) — much higher than the temperatures where superconductivity is expected to occur in these conditions.
