News that some zoos have stopped feeding monkeys fruit has led people to suggest humans avoid it too. But that ignores a few crucial details, says James Wong

The development of new bone can be a multistep process: first, stem cells differentiate into cartilage cells. Next, the cartilage cells become bone cells. But that's not all: the cells must experience some mechanical str...

A wireless sensor small enough to be implanted in the blood vessels of the human brain could help clinicians evaluate the healing of aneurysms -- bulges that can cause death or serious injury if they burst. The stretchab...

An individual's trust in institutions such as the CDC, and how close they live to a recent measles outbreak, may affect their attitudes on measles vaccination.

Engineers have developed a magnetically steerable, thread-like robot that can actively glide through narrow, winding pathways, such as the labrynthine vasculature of the brain.

The pathogen Clostridium difficile, which causes one of the most common hospital-acquired infections in the United States, may have accomplices that until now have gone largely unnoticed.

The enzyme transhydrogenase plays a central role in regulating metabolic processes in animals and humans alike. Malfunction can lead to serious disorders. For the first time, structural biologists have now visualized and...

For years, women have been told that weight gain could lead to heart disease. A new study indicates that it is the location of the fat that matters most, with abdominal fat representing the greatest harm and not overall ...

During embryogenesis, dozens of types of neurons with distinct functions come together to form the circuits that drive our thoughts and actions. They are generated by progenitor cells, which produce them one after the ot...

Researchers look at preeclampsia when it coincides with type 1 diabetes. By studying patients with elevated lipoproteins, these researchers determined that the diabetic patients with a certain phenotype were at greater r...

Psychologists warn parental burnout needs to be taken more seriously by both partners and clinicians. A new study reveals burnt out parents experience escape ideations, and show an increased risk of neglect and violence ...

Researchers examined the effects of three healthy diets emphasizing different macronutrients -- carbohydrates, proteins, or unsaturated fats -- on a biomarker that directly reflects heart injury.

Patients with gout are at increased risk of chronic kidney disease and kidney failure, according to new research.

The study analyzed data from studies across eight different psychiatric disorders, including major depressive disorder, bipolar disorder, borderline personality disorder, schizophrenia, eating disorders, and others. The ...

Median survival after lung transplant is less than six years. To see what might help lung transplant recipients live longer, researchers analyzed US lung transplant data, focused on immunosuppression regimes, and found a...

A review of the autopsy reports of 252 men and women who died of acquired immunodeficiency syndrome (AIDS) in New York City between 1984 and 2016 reveals several long-term trends in combatting the epidemic.

The genetics of circadian rhythms have been well studied in recent years, but much less is known about other types of genes that play a role in sleep. Now, by studying a family with several members who require significan...

Neuroscientists were able to prove that speech recognition in humans begins in the sensory pathways from the ear to the cerebral cortex and not, as previously assumed, exclusively in the cerebral cortex itself.

A growing number of middle- and high-school students are being exposed to second-hand aerosols from e-cigarettes by living with or being around individuals who are vaping, according to data from a national survey.

A team of scientists from the U.S. Department of Energy's Brookhaven National Laboratory and Lawrence Berkeley National Laboratory designed, created, and successfully tested a new algorithm to make smarter scientific mea...

A major new study on the association between blood glucose levels and risks of organ impairment in people with type 1 diabetes can make a vital contribution to diabetes care, in the researchers' view.

Scientists have investigated the activity of stem cells in the brain of mice and discovered a key mechanism that controls cell proliferation. According to the researchers, the gene regulator Id4 controls whether stem cel...
