French scientists identify a new giant virus, which carries the genome of a smaller virus and a new breed of mobile DNA.

Brain cells called pericytes can be reprogrammed into neurons with just two proteins, pointing to a novel way to treat neurodegenerative disorders.

Disrupting a small part of the brain with a magnetic field can reduce people’s prejudice towards good news.

Reversible marks on the genome allow honeybees to swap between lives as nurses and foragers.

In diabetic mice, the cells of the pancreas don’t die, but rather revert to an earlier state incapable of producing the insulin the body needs.

A massive project involving hundreds of scientists suggests that very little—if any—of the human genome is truly non-functional.

Identical resistance genes in soil and clinical bacteria hint at dangerous genetic arms trade that is aggravating the antibiotic-resistance crisis.

Information picked up while we slumber can stay with us when we awake, even if we aren’t aware of it.

Chemicals that change the way DNA is packaged could improve the effects of current antipsychotics.

To cope with a growing shortage of hearts, livers, and lungs suitable for transplant, some scientists are genetically engineering pigs, while others are growing organs in the lab.

Genomic analyses reveal that the polar bear evolved between 4 and 5 million years ago, far earlier than previous studies had estimated.

A bacterial protein refolds itself into two dramatically different shapes with distinct roles.
