A new study of human skeletal remains from the wreck of the 16th century English warship Mary Rose suggests that whether a person is right- versus left-handed may influence how their clavicle bone chemistry changes as they age.

Your brain not only processes what you see but continuously makes predictions based on your experiences. This process may be less fine-tuned in people with autism, research suggests. When someone throws a ball at you, you almost immediately know to catch it -- even before you consciously realize it. In the past, people thought that

A new, large study found that lack of health insurance coverage accounts for a significant proportion of racial and ethnic disparities in advanced-stage diagnosis of multiple cancers. A new, large study led by American Cancer Society (ACS) researchers found that lack of health insurance coverage accounts for a significant proportion of racial and ethnic disparities

Increasing ketones in the blood through a keto diet or supplements may help put irregular menstrual cycles back on schedule or even restart a period that appears to have stalled for good, new research suggests.

In common marmosets, the brain regions that process social interactions develop very slowly, extending until early adulthood, like in humans. During this time, all group members are involved in raising the infants, which contributes to the species' strong socio-cognitive skills. In common marmosets, the brain regions that process social interactions develop very slowly, extending until

Military musicians returning from the Napoleonic wars established Britain's first brass bands earlier than previously thought, new research reveals. The study undermines the idea that brass bands were a civilian and exclusively northern creation.

New research suggests older adults wait 3-6 months after a heart attack before elective noncardiac surgery to reduce the risk of serious complications like stroke or another heart attack. After a heart attack, aging adults face double or triple the risk of life-threatening complications -- like a debilitating stroke or another heart attack -- when

Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists have identified new clusters of cells with differing patterns of gene expression in the amygdala of humans and non-human primates.

A new analysis has revealed detailed 3D maps of the internal structures of multiple tumor types. These cancer atlases reveal how different tumor cells -- and the cells of a tumor's surrounding environment -- are organized, in 3D, and how that organization changes when a tumor spreads to other organs. The detailed findings offer scientists

Researchers have found a process by which the brain guards against attack by the immune system. In mice with multiple sclerosis, such 'guardian' proteins that train the immune system were drastically depleted, and replenishing them improved symptoms, according to a new study. The brain constantly engages in dialogue with the body's immune system. Such communication

New research into the long-term dynamics of transplanted stem cells in a patient's body explains how age affects stem cell survival and immune diversity, offering insights that could make transplants safer and more successful. For the first time, scientists have tracked what happens to stem cells decades after a transplant, lifting the lid on the

An international research team has investigated how nanoplastic particles deposited in the body affect the effectiveness of antibiotics. The study showed that the plastic particles not only impair the effect of the drugs, but could also promote the development of antibiotic-resistant bacteria. In a recent study, an international research team with significant involvement from MedUni
