The instability at the beginning of the solar system: Does it portend an undiscovered planet?

The instability at the beginning of the solar system: Does it portend an undiscovered planet?

All stars, including our sun, are born from a cloud of dust and gas. This cloud can also seed planets that will orbit the star. Credit: NASA/JPL-Caltech Michigan State University’s Seth Jacobson and colleagues in China and France have unveiled a new theory that could help solve a galactic mystery of how our solar system …

Supernova reveals its secrets to team of astronomers

Supernova reveals its secrets to team of astronomers

This schematic shows the various ejecta and winds (red and purple) given off by the exploding star (left, yellow). The common-envelope disk (blue) surrounds both stars, the one exploding as a supernova and its binary partner (not shown). The boundary layer around the common-envelope disk is the source of the hydrogen the team detected. Credit: …

Genome of girl with severe lupus pins down genetic target for treatments

There is no cure for lupus, a disease that causes the body’s immune system to attack itself. But researchers are now closer to a genetic explanation for the puzzling condition, thanks to the genome of a child with a rare inherited form of the disease. A new study fingers a gene called TLR7 that helps …

Which Animal Viruses Could Infect People? Computers Are Racing to Find Out.

Which Animal Viruses Could Infect People? Computers Are Racing to Find Out.

Colin Carlson, a biologist at Georgetown University, has started to worry about mousepox. The virus, discovered in 1930, spreads among mice, killing them with ruthless efficiency. But scientists have never considered it a potential threat to humans. Now Dr. Carlson, his colleagues and their computers aren’t so sure. Using a technique known as machine learning, …

Discovery of the one-way superconductor, thought to be impossible

Discovery of the one-way superconductor, thought to be impossible

Artist Impression of a superconducting chip. Credit: TU Delft Associate professor Mazhar Ali and his research group at TU Delft have discovered one-way superconductivity without magnetic fields, something that was thought to be impossible ever since its discovery in 1911—up until now. The discovery, published in Nature, makes use of 2D quantum materials and paves …
