Researchers said today that lightning strikes billions of years ago may have freed up phosphorus required for the formation of biomolecules essential to life. A bolt of lightning can create glassy rocks called fulgurites by superheating and sometimes vaporizing surface rock, freeing phosphorus locked inside, Reuters reports.

Dyret, a four-legged robot, has the ability to adjust the length of its legs in adapting to varying terrain, reports Tech Xplore. "The robot uses a camera to see how rough the terrain is, and it uses sensors in the legs to feel how hard the walking surface is," says researcher and senior lecturer Tonnes Nygaard. "The robot continuously learns about the environment it's walking on and, combined with the knowledge it gained indoors...

A team of researchers led by the University of Cambridge found that out of the more than 300 COVID-19 machine learning models described in scientific papers in 2020, none is suitable for detecting or diagnosing COVID-19 from standard medical imaging, due to biases, methodological flaws, lack of reproducibility, and "Frankenstein datasets", reports Tech Xplore. "... any machine learning algorithm is only as good as the data it's trained on," said first author Dr. Michael Roberts...
A supermassive black hole (SMBH) is on the move, it seems. About 230 million light-years from Earth, the black hole is moving peculiarly at a speed of around 177,000 kilometres per hour, reports CNET. In a study published in the Astrophysical Journal, a team of astronomers cited abnormal activity in galaxy J0437+2456. A possible explanation is that the SMBH is from an external galaxy that collided recently with J0437+2456 ... but there is a big hole in...
