The first complete model to describe the role that serotonin plays in brain development and structure has been created by researchers. Serotonin is an important neuromodulator of brain development and the structure and function of neuronal (nerve cell) circuits.

A new research discovery is opening a window on cell biology rarely seen before. The work has revealed a real-time look at how genetic information travels within a living cell. The discovery, observed through a specially designed high-powered microscope, significantly alters current understanding…

Both acute kidney injury and chronic kidney disease were common in patients undergoing major vascular surgical procedures and were associated with an increase in long-term cardiovascular-specific death compared with patients with no kidney disease, according to a study.

Everybody knows that a buildup of the wrong kind of fats can cause cardiovascular disease. A new study in nematode worms and mice also finds that a protein that transports fats around the body can hinder protective processes in cells and affect life span.

Imagine standing on a basketball court, throwing the basketball and watching it arc into the net. Chances are you'll make that shot without a problem if you've been practicing, according to new research.

Using mobile phones for research is not new. However, interpreting the data collected from volunteers' own smart phones-which has the potential to emulate randomized trials-can advance research into human behavior. Scientists have just demonstrated the potential of using smart phones for conducting…

We can learn to empathize with strangers. Surprisingly, positive experiences with people from another group trigger a learning effect in the brain, which increases empathy, researchers reveal. They add that only a handful of positive learning experiences already suffice for a person to become more…

Prohibiting runway models from participating in fashion shows or photo shoots if they are dangerously thin would go a long way toward preventing serious health problems among young women -- including anorexia nervosa and death from starvation -- according to experts.

Field study of police lineups suggests courts must pay attention to initial witness confidence ratings and police departments should continue using traditional, simultaneous procedure.

Examination of thousands of genes from nearly 150 human brains shows the circadian rhythm of brain gene activity changes with aging, according to a first-of-its-kind study.

Inorganic mercury, which was previously thought to be a less harmful form of the toxic metal, is very damaging to key cell processes, new research demonstrates.

Those who commute home after working the night shift may be at high risk for drowsy driving crashes because of disruption to their sleep-wake cycles and insufficient sleep during the night

Although medical science has long regarded sudden cardiac arrest as a deadly condition that strikes without warning, a new study shows for the first time that many patients experience warning symptoms up to a month before having a cardiac arrest.

After observing that some gastrointestinal disease in premature human and mouse infants progresses only when certain immune system white blood cells go into inflammatory overdrive, researchers have found that giving large doses of vitamin A to mice converts those blood cells into inflammation…

Family-level preventive intervention can lead to improved behavioral health outcomes for military families affected by wartime deployment, a new study reports. Results highlight significant reductions in anxiety and depression symptoms among deployed parent, home-based parent and their children…

Researchers have quantified one of the most important and hard-to-measure phenomena in molecular evolution: the effect of genetic recombination on a species' capacity of adaptation.

Long-term analysis shows cost-effectiveness of WATCHMAN left atrial appendage closure device over warfarin and NOACs in reducing stroke risk in non-valvular atrial fibrillation patients.

Workforce homogeneity limits creativity, discovery, and job satisfaction; nonetheless, eighty-one percent of US science, technology, engineering, and math (STEM) university faculty members are men. The relative dearth of women in the field is a long-recognized problem -- but it's one that may be on…

A research team has leveraged its organ-on-a-chip technology to develop a model of the human small airway in which lung inflammatory diseases, such as chronic obstructive pulmonary disease (COPD), the third leading cause of mortality worldwide, and asthma can be studied outside the human body.

For women with low-risk pregnancies who plan to give birth at home with the help of a midwife, there is no increased risk of harm to the baby, compared with a planned hospital visit, according to new research in Canadian Medical Association Journal.

Wearable activity trackers that promise to monitor physical activity, sleep and more are becoming increasingly popular with health-conscious consumers. A recent study has found that the trackers are better at measuring some metrics than others.

A drug that boosts activity in the brain's "garbage disposal" system can decrease levels of toxic proteins associated with Alzheimer's disease and other neurodegenerative disorders and improve cognition in mice, a new study by neuroscientists has found.

Building upon previous research, scientists report that a protein called Wnt5a acts on a pair of tumor-surface proteins, called ROR1 and ROR2, to accelerate the proliferation and spread of chronic lymphocytic leukemia cells, the most common form of blood cancer in adults.

Patients who have had a stroke in the back of the brain are at greater risk of having another within two years if blood flow to the region is diminished, according to results of a multicenter study.
