In Newly Created Life-Form, a Major Mystery

Scientists have created a synthetic organism that possesses only the genes it needs to survive. But they have no idea what roughly a third of those genes do.

neuroscience

The Beasts That Keep the Beat

New insights from neuroscience — aided by a small zoo’s worth of dancing animals — are revealing the biological origins of rhythm.

Q&A

In Warm, Greasy Puddles, the Spark of Life?

The biologist David Deamer proposes that life evolved from a collection of interacting molecules, probably in a pool in the shadow of a volcano.

ecology

A Timely Fix for a Grand Theory of Nature

A disarmingly simple model of ecology does everything well — except predict how rapidly nature can change. Can it become more realistic while still avoiding all of biology’s messy complexities?

Quantized Columns

Deep Secrets and the Thrill of Discovery

The biologist Sean B. Carroll rediscovers the scientific thrill of an unexpected revelation.

How to Build Life in a Pre-Darwinian World

Perhaps chemistry played a more instrumental role in the origin of life than scientists thought.

Scientists Debate Signatures of Alien Life

Searching for signs of life on faraway planets, astrobiologists must decide which telltale biosignature gases to target.

Q&A

Searching for the Algorithms Underlying Life

The biological world is computational at its core, argues computer scientist Leslie Valiant.

neuroscience

New Clues to How the Brain Maps Time

The same brain cells that track location in space appear to also count beats in time. The research suggests that our thoughts may take place on a mental space-time canvas.
