How Life (and Death) Spring From Disorder

Life was long thought to obey its own set of rules. But as simple systems show signs of lifelike behavior, scientists are arguing about whether this apparent complexity is all a consequence of thermodynamics.

Dividing Droplets Could Explain Life’s Origin

Researchers have discovered that simple “chemically active” droplets grow to the size of cells and spontaneously divide, suggesting they might have evolved into the first living cells.

On the Moon’s Far Side, Clues to a Cataclysm?

A mission to collect samples from the far side of the moon could answer questions about a barrage of asteroids nearly 4 billion years ago.

Earth scientists hope that their growing knowledge of the planet’s early history will shed light on poorly understood features seen today, from continents to geysers.

In the Deep, a Drive to Find Dark Matter

Elena Aprile now leads the world’s most sensitive dark-matter search. But before she could build her first detector, she had to make herself out of titanium.
