Kidneys sniff out signals from gut bacteria for cues to lower blood pressure after meals. Our understanding of how the symbiotic microbes affect health is becoming much more molecular.

To better understand the molecules described by the latest prize in medicine, we will need the technique recognized by the latest prize in chemistry.

Sex might help natural selection purge excessive mistakes from our genes.

The proteins that unravel as the temperature starts to rise turn out to be among the most vital.

The circadian clock is in nearly every cell, and researchers have untangled many of its secrets. But sleep has been harder to pin down.

Powerful new experiments have uncovered some of the molecular underpinnings of sleep.

A virus that causes crippling birth defects has been shown to do something else: It changes thousands of messages coming from DNA that control normal cellular activities.

A new look at the reasons why organisms missing pairs of genes sometimes do much better than normal.

In a monumental set of experiments, spread out over nearly two decades, biologists removed genes two at a time to uncover the secret workings of the cell.
