The decline of key Atlantic currents is underway, and it's been flooding parts of the US for 20 years
New research has linked sea level rise and an increase in flooding in the U.S. Northeast over the past 20 years to the breakdown of the Atlantic Meridional Overturning Circulation (AMOC).
Scientists solve mystery of how orange cats got their coats — and why so many are male
Researchers have discovered how orange cats got their coats — and why so many of them are male. The coat color comes from a genetic mutation on the X chromosome of orange, calico and tortoiseshell cats.

The sun has released several powerful M- and X-class solar flares over the past few days, resulting in radio blackouts around the world.
Physicists take step toward a 'theory of everything'
A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
Dinosaur age tsunami revealed from tiny chunks of Japanese amber, study finds
Amber deposits in Japan show unique deformations that suggest trees were swept out to sea during a tsunami about 115 million years ago, giving paleontologists a new way to identify past tsunamis.
