Pluripotent cells can help regenerate tissues and maintain long life—and they may also help animals jumpstart drastically new lifestyles.

Bottlenose dolphins can recognize and respond to their own “signature whistles,” strengthening the evidence that these whistles function like names.

Researchers analyze smoke generated during surgical tumor removal to distinguish healthy and diseased tissues in real time.

The cell fragments play a role in the body’s first line of defense against bacterial infection, helping white blood cells grab blood-borne bacteria in the liver.

Researchers identify the signaling program that enables finger and toenail stem cells to direct digit regeneration after amputation.

During frogs’ hectic mass breedings, females often die. But one species appears to have found a work-around: males harvest and fertilize their partners' eggs after her death.

Researchers find that reducing mitochondrial protein production in some animals can increase lifespan by activating a protective stress response.

Synthetic biologists are looking to analog, not digital, circuits to create cell-based calculators that can add, divide, and even perform algorithms.

For the first time, researchers visualize zebrafish memory retrieval in real time.

Researchers identify a herpesvirus gene persisting in the cells of calves suffering from malignant catarrhal disease.

Researchers use bacteria to deliver radiation to shrink pancreatic tumors in mice.

Just the flavor of beer is enough to boost dopamine in brain areas related to reward—especially in men with alcoholic relatives.

Researchers track the evolution of HIV in a single patient to understand what drives the production of broadly neutralizing antibodies.

Scientists are using genetic techniques to target diseases that affect how we see, hear, smell, taste, and feel.

Researchers find that temporary double-stranded DNA breaks commonly result from normal neuron activation—but expression of an Alzheimer’s-linked protein increases the damage.
