Buildup of a DNA-repair protein in brain cells spurs shut-eye in the fish, a study finds, and similar results in mice suggest the mechanism is widespread in animals.

Abnormal sympathetic neuron growth leads to simultaneous activation of clusters of sensory neurons, causing the difficult-to-treat sensation.

While exploring suspended animation in mice, scientists discover how an enzyme can protect the brain from dangerously low levels of oxygen.

A new study suggests that DNA synthesized in the cell cytoplasm drives retinal cell death in an advanced form of age-related macular degeneration, a leading cause of blindness.

Mice lacking irisin didn’t exhibit the cognition improvements that typically follow exercise, and in mouse models of Alzheimer’s disease, treatment with the hormone reduced cognitive decline.

Researchers studying rats claim to have found a novel connection between damage on one side of the brain and problems with the posture or movement of limbs on the opposite side of the body.

Symptoms documented in cases of long COVID are wide ranging and variable.

Researchers identify a role for PIEZO1 in tendon adaptation, and show that people with certain versions of the Piezo1 gene tend to be better jumpers.

Centuries of folklore backed by scientists in the early 1900s have perpetuated the idea that menstruating women can exert dangerous forces.

A year and a half into the pandemic, the long-term effects of SARS-CoV-2 infection are garnering more research attention as millions of long COVID patients emerge.

Vesicles containing fragments of the organelles released from stressed adipocytes protect the heart against oxygen deprivation, a study in mice shows.

Last night, two women publicly accused the famed anti-aging researcher of inappropriately bringing up sex in the workplace, and they say they are not his only victims.

Researchers identify a protein that promotes changes in adipose tissue in vitro and in pregnant mice and may help protect against gestational diabetes in humans.

Obese mice that exercised while pregnant gave birth to pups that grew up free of the metabolic issues present in the adult young of sedentary obese mothers—possibly by staving off epigenetic changes to a key metabolic gene.
