Africa has new purple-clad warriors more than 200 feet beneath the ocean’s surface. Deep-diving scientists spotted dazzling fairy wrasses—previously unknown to science—in the dimly lit mesophotic coral reefs of eastern Zanzibar, off the coast of Tanzania.

Despite the immense importance of the liver for human health, the diversity of individual liver cell types and the associated molecular and cellular processes in both healthy and diseased tissue have not yet been fully investigated, until now.

Adults with a first-degree relative with Alzheimer's disease perform more poorly on online paired-learning tasks than adults without such a family history, and this impairment appears to be exacerbated by having diabetes or a genetic variation in the apolipoprotein E (APOE) gene linked to the disease.

We may take it for granted that the sex of an animal is established at birth and doesn't change. However, about 500 species of fish change sex in adulthood, often in response to environmental cues. How these fish change sex has, until now, been a mystery.

A new protein called KHNYN has been identified as a missing piece in a natural antiviral system that kills viruses by targeting a specific pattern in viral genomes.

Scientists have decoded the genome of black-eyed peas, offering hope for feeding Earth's expanding population, especially as the climate changes.

Researchers have shown that a protein called Ran plays a key role in the mobility of ovarian cancer cells. The team demonstrated that these cells cannot migrate from cancerous sites without the help of Ran.

Researchers have now mapped the protein expression of the sinus node in mice. This means that they can now measure and analyze the proteins that make up the sinus node.

A flamingo lives 40 years and a human being lives 90 years; a mouse lives two years and an elephant lives 60. Why? What determines the lifespan of a species?

Following gene therapy, the retina can restructure itself and regain normal light responses, according to research.
