Scientists report a time-keeping mechanism in liver cells that helps sustain key organ tasks can contribute to diseases when its natural rhythm is disrupted.

With nearly breakneck speed, the demands of work productivity in today's society seem to have increased tenfold. Enter multitasking as a way to cope with the insistence that tasks be completed almost immediately. Previou...

A new study examines one key stress-inducing circumstance -- the effects of social hierarchy -- and how cells respond to the hormones that are released in response to that stress.

A new study has found that an antimicrobial chemical called triclosan is abundant in dust -- and linked to changes in its genetic makeup. The result is dust with organisms that could cause an antibiotic-resistant infecti...

Why do orally-administered drugs for diabetes work for some people but not others? According to researchers, bacteria that make up the gut microbiome may be the culprit.

A new computational model gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding of cancerous tumor growth, wound healing, and embryonic development...

In a sweeping new study, psychologists have found that a series of self-guided, internet-based therapy platforms effectively reduce depression.

Last week, news of CRISPR-engineered babies launched a firestorm of debate on the future of human reproduction: Is it safe? Is it ethical? Do we now have the ability to "play God"? But even as scientists, ethicists, and ...

(University of California - San Diego) Home energy storage systems might save you money, but under current policies, they would also often increase carbon emissions. That is the conclusion reached by a team of researcher...

For scientists wrestling with problems as diverse as containing superhot plasma in a fusion reactor, improving the accuracy of weather forecasts, or probing the unexplained dynamics of a distant galaxy, turbulence-spawni...

Researchers report single tau proteins have different shapes, and the folds of the molecules could help doctors to predict which type of dementia a person is likely to suffer from.

After creating a memory in a context, engram cells encoding the memory in the hippocampus become more excitable when the context is repeated a short time later, researchers report.

Researchers report the brains of those who practice meditation are less affected by negative feedback than those who do not meditate. The study reports this could be due to altered dopamine levels caused by the act of me...

A new computational model developed by researchers from The City College of New York and Yale gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding...

Scientists who recently identified the molecular start of Alzheimer's disease have used that finding to determine that it should be possible to forecast which type of dementia will develop over time -- a form of personal...

For the first time, researchers have fabricated light-guiding structures known as waveguides just over one micron wide in a clear silicone commonly used for biomedical applications. The tiny, flexible waveguides can be u...

Researchers report low levels of GABA producing bacteria is associated with brain signatures of depression. They believe it may be possible to treat clinical depression by increasing GABA producing bacteria.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth - this was discovered by researchers two years ago. In a follow-up study, scientists report that this drug cockt...

According to some estimates, up to one in three people around the world may experience severe anxiety in their lifetime. Researchers have now revealed a previously unknown mechanism underlying anxiety. Targeting this bio...

Cell biologists have developed a new method for measuring how mechanical forces in cells are processed.

For the first time, researchers have identified that an immune cell subset called gamma delta T cells that may be causing and/or perpetuating the systemic inflammation found in normal aging in the general geriatric popul...

A new study supports body mass index as a useful tool for assessing obesity and health.
