Phys.org / Butterfly ranges shift worldwide amid climate change, with most species expanding their reach

A global analysis of range-shift records for 1,758 butterfly species—10% of known butterfly species—found that 80% had expanded their range and that 79% of all recorded range shifts were linked to climate change and extreme ...

Phys.org / An ultramassive white dwarf half Earth's size may hold a rare oxygen-neon core

Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The finding is important because the composition of a white dwarf's core ...
