Last week, NASA's Mars rover Curiosity stumbled upon a dark grey, golf ball-sized object that looks nothing like the typical red-orange rocks typically seen on Mars.

Researchers provide unprecedented evidence that basal forebrain pathology precedes and predicts both entorhinal pathology and memory impairment in people with Alzheimer's disease.

Regaining full injury is more than just physical -- it requires retraining the brain, say researchers.

Rodents that had been exposed to stress had a weakened alcohol-induced dopamine response and voluntarily drank more alcohol compared to controls, a new study has found. The blunted dopamine signaling to ethanol arose due...

A woman living on a dialysis machine is grown a new kidney using her own cells. A father struggling with age-related vision loss has his eyesight restored. A soldier suffers extensive burns and has his skin regenerated. ...

Records of a partial skeleton of a castaway found in the 1940s on the Pacific island Nikumaroro shows some similarities to Amelia Earhart, but other forensics scientists are not sure the science holds up.

The discovery of a vast reservoir of water - as big as the largest freshwater lakes - could help reveal how eruptions occur, and how continental crust forms

The Axsis robot can manage the fine movements needed for cataract surgery. Its makers hope it will cut complications, and find uses in other parts of the body

In the unlikely event of the zombie apocalypse, it would take less than two months for the undead to take control of the city, says a new study.

Exercise during pregnancy may be as effective in protecting the next generation from age-related health risks as efforts made during the offspring's own adulthood. Researchers think that short-term lifestyle changes duri...

Fathers who exercise regularly before their children are conceived may program their offspring's genes with an increased risk for metabolic disorders, according to new research. The surprising results point to the identi...

Giant ground sloths were large, lumbering beasts that lived in the Americas during the Ice Age. Thomas Jefferson is credited with discovering one species.

Scientists who use postmortem brain tissue to study alcohol's effects on brain structure and function will find this research interesting. Phosphatidylethanol (PEth) is an alcohol metabolite and its concentration in whol...

Using prominent, graphic pictures on cigarette packs warning against smoking could avert more than 652,000 deaths, up to 92,000 low birth weight infants, up to 145,000 preterm births, and about 1,000 cases of sudden infa...

New research suggests that transmembrane TNF-alpha may allow HIV to infect kidney cells that not express the major HIV-1 CD4 receptor. The findings could provide insights on how patients develop HIV-1 associated nephropa...

People who meet recommended weekly physical activity guidelines are still at risk of developing chronic disease if they spend too much non-exercising time sitting. Researchers found that women sit more as they grow older...

Genes, specifically those that modulate dopamine in the brain, may play a role in a person's propensity to embrace or avoid exercise.

Previous studies show that as little as one week of overeating can impair glycemic control and insulin sensitivity. Just in time for holiday feasting, a new study finds that exercise can protect fat tissue from changes i...

Patients with obesity who swallowed gas-filled balloon capsules designed to help them eat less, lost 1.9 times more weight than patients who relied on diet, exercise and lifestyle therapy alone, according to new research...
