Bright colors in the animal kingdom: Why some use them to impress and others to intimidate

Research at the University of Arizona found a strong link between bright color use and ancestral day-night activity patterns. Species that use bright colors for sexual signals were descended from diurnal ancestors, while those using aposematism had nocturnal ancestors. This pattern holds across land vertebrates with over 40,000 species.

Scientists discover mechanism that can cause collapse of great Atlantic circulation system

Researchers found that subsurface warming in the North Atlantic precedes the release of massive icebergs from Canada and the US, leading to a reduction in surface salinity and AMOC collapse. This finding sheds light on the sequence of events responsible for the collapse of the Atlantic meridional overturning circulation system.

New cancer drug candidate targets immune system “brakes”

Researchers have designed a potential therapeutic that dampens the activity of regulatory T cells, which can prevent the immune system from unleashing its full potential against tumor cells. The molecule, known as FOX3P, acts as a transcription factor for many Treg genes but isn't vital for other types of T cells.
