The results of a recent study provide insights into the mechanism by which estrogen can decrease insulin resistance and the production of glucose, reducing incidences of Type 2 diabetes mellitus.

New rules governing international track and field competitions would require some women to medically reduce their testosterone levels to compete. A new study suggests the regulations are rooted in flawed science.

In the largest study to date on phthalates and postmenopausal breast cancer, a cancer epidemiology researcher found no association between breast cancer risk and exposure to the plasticizing and solvent chemicals used in...

Researchers have developed and evaluated a machine learning approach of using patient core needle biopsy data to identify the risk that atypical ductal hyperplasia (ADH) breast lesions may upgrade to cancer. This knowled...

Researchers have discovered how overactive DNA repair systems can lead to retinal damage and blindness in mice. A DNA repair enzyme called Aag glycosylase becomes hyperactive, provoking an inflammatory response that prod...

In a new study, researchers report that hearing impairment is associated with accelerated cognitive decline with age, though the impact of mild hearing loss may be lessened by higher education.

When faced with painful gallstones, pregnant women should consider postponing surgical treatment until after childbirth, new study results show.

Animal experiments have shown that caloric restriction causes cellular changes that can prevent diseases.

A new study has found that exercise efficiency decreases in recreational cyclists when they pedal very hard, incorporating more revolutions per minute.

The bacterial pathogen Helicobacter pylori owes its worldwide distribution to its genetic adaptability. Microbiologists have identified an enzyme that plays a vital role in the flexible control of global gene expression ...

Induced pluripotent stem cells, the workhorse of many regenerative medicine projects, start out as differentiated cells that are reprogrammed to pluripotent stem cells by exposure to a complex set of genetic cocktails.

New research reveals that parts of the neuron are far more complex than once thought.

Human beings are not the only ones who suffer from stress -- even microorganisms can be affected. Now, researchers have devised a new method to study how single biological cells react to stressful situations. Understandi...

Optical frequency combs are laser sources whose spectrum consists of a series of discrete, equally spaced frequency lines that can be used for precise measurements. In the last two decades, they have become a major tool ...

Electronics rely on the movement of negatively-charged electrons. Physicists strive to understand the forces that push these particles into motion, with the goal of harnessing their power in new technologies. Quantum com...

Researchers report hearing impairment is associated with an increased rate of cognitive decline as we age. However, the study revealed the impact of hearing loss on cognition was lessened for those who had a college leve...

A new study makes the case that obstructive sleep apnea should be viewed as a low grade chronic inflammatory disease.

A team of researchers from the Department of Energy's Oak Ridge and Los Alamos National Laboratories has partnered with EPB, a Chattanooga utility and telecommunications company, to demonstrate the effectiveness of metro...

According to researchers, physical coordination is more beneficial in larger groups. The findings could help improve current physical rehabilitation techniques by training patients in groups to improve movement skills.

Using CRISPR gene editing technology, researchers discover increased activity in neurons deficient in the CNTN5 or EHMT2 genes may cause ASD related characteristics in humans.

A new study reveals couples who create art or play board games together release oxytocin. Researchers report males release 2 to 2.5 times more oxytocin when creating art with their loved one.

Researchers report sleep can help immune cells attach to targets and help fight infection. The study reveals how sleep assists the body in fighting infections, whereas conditions like chronic stress can make the body mor...
