The Cause of Depression Is Probably Not What You Think

By JOANNA THOMPSON

Depression has often been blamed on low levels of serotonin in the brain. That answer is insufficient, but alternatives are coming into view and changing our understanding of the disease.

Mathematicians Find an Infinity of Possible Black Hole Shapes

By STEVE NADIS

In three-dimensional space, the surface of a black hole must be a sphere. But a new result shows that in higher dimensions, an infinite number of configurations are possible.

I Saw the Sign
Humans can correctly guess the meaning behind the gestures made by wild chimps and bonobos, reports Victoria Gill for BBC News. Researchers think that our ancestors used similar gestures to communicate before they developed language. Gestures are not only useful tools for communication. Mounting evidence suggests that they serve an important role in perception and cognition, too. Raleigh McElvery wrote about this for Quanta in 2019.


Io's Ire 
A recent eruption on Jupiter's intensely volcanic moon Io emitted a mix of chemicals that startled observers, reports Oliver Whang for The New York Times. Studying it could help scientists better understand Io's volcanoes and their interactions with Jupiter. Gas emitted by Io's volcanoes can get captured by Jupiter's magnetic fields and power the planet's auroras. In 2021 Robin George Andrews reported for Quanta that these auroras are why Jupiter is unexpectedly warm.
