For most of human history, our view of "close to the Sun" was defined by the orbit of Mercury, with its 88-day orbit and barren, baking surface. But from the moment we started discovering exoplanets, it became very clear that our own Solar System was anything but a guide to the rest of the galaxy. Planets with orbits only a few days long are strikingly common, with the proximity to the star creating things that seem bizarre from our perspective: metal vapor in the atmosphere, or atmospheres puffed out to ridiculously low densities.

Now, we can apparently add an additional oddity: overlapping magnetic fields. Researchers have found a star/planet combo that experiences periodic brightening, which they ascribe to the interactions between the magnetic fields of both bodies.

Looking for repetition

This is one of those cases where theory came before discovery. People had already proposed that a planet orbiting close to its host star could interact with it if its magnetic field were sufficiently strong. And, in a number of cases, researchers have found evidence that this is happening, with one case of an extremely young star emitting flares seemingly in response to the orbit of its innermost planet.

The US Endangered Species Act compels the government to identify species at risk of extinction and devise plans to restore populations and the habitats they depend on. It has seen some spectacular successes, such as the restoration of the bald eagle to much of its original range. But over 2,300 plant and animal populations remain on the list, requiring ongoing government intervention.

On Thursday, it was announced that all of those species would see their genomes sequenced and tissue samples preserved to aid future conservation efforts. The work will be done by a partnership between two unexpected parties. One is the US government, which has generally attempted to undercut the Endangered Species Act as part of its anti-regulatory efforts. It is joined by Colossal Biosciences, a biotech company that has a controversial take on what actually constitutes a species.

Colossal has always said it had a conservation focus, but its headline-grabbing efforts have been directed toward restoring species that have been driven to extinction. It intends to do that by developing a combination of gene editing and reproductive technologies that it expects it can profitably license. But its dire wolf announcement, in which only a tiny handful of genetic changes were edited in to grey wolves, have raised some questions about its seriousness regarding these efforts.
