People with prediabetes who go to bed later, eat meals later and are more active and alert later in the day -- those who have an "evening preference" -- have higher body mass indices compared with people with prediabetes who do things earlier in the day, or exhibit morning preference. The higher BMI among people with evening preference is related to their lack of sufficient sleep, according to a University of Illinois at Chicago-led study.

A new study in the journal Rheumatology indicates that being exposed to secondhand smoke in childhood could increase the risk of someone developing arthritis as an adult.

New research, published in the European Heart Journal [1] today (Wednesday), has shown deaths from conditions that affect the blood supply to the brain, such as stroke, are declining overall in Europe but that in some countries the decline is levelling off or death rates are even increasing.

A powerful psychedelic compound found in ayahuasca can model near-death experiences in the brain, a study has found.

Near-death experiences, or NDEs, are significant psychological events that occur close to actual or perceived impending death. Commonly reported aspects of NDEs include out of body experiences, feelings of transitioning to another world and of inner peace, many of which are also reported by users taking DMT.

Eating breakfast before exercise may "prime" the body to burn carbohydrates during exercise and more rapidly digest food after working out, University of Bath researchers have found.

Scientists from the University's Department for Health, working with colleagues at the universities of Birmingham, Newcastle and Stirling, were studying the effect of eating breakfast versus fasting overnight before an hour's cycling. In a control test breakfast was followed by three hours' rest. The volunteers ate a breakfast of porridge made with milk two hours before exercise.

BUFFALO, N.Y. -- A class of proteins that has generated significant interest for its potential to treat diseases, has for the first time, been shown to be effective in reducing relapse, or drug-seeking behaviors, in a preclinical study.

Published online in July in Biological Psychiatry, the University at Buffalo research reveals important new information about the molecular changes that occur in the brain when an individual takes cocaine, and how these molecules can be targeted to reduce drug-seeking behaviors during withdrawal.

COLUMBUS, Ohio - Researchers have found a surprising new explanation of how young brains are shaped for sexual behavior later in life.

Immune cells usually ignored by neuroscientists appear to play an important role in determining whether an animal's sexual behavior will be more typical of a male or female, according to research led by Kathryn Lenz, an assistant professor of psychology and neuroscience at The Ohio State University.

The study, which was done in rats, appears in the Journal of Neuroscience.

Blood platelets are like the sand bags of the body. Got a cut? Platelets pile in to clog the hole and stop the bleeding.

But genetic mutations, infections and even radiation from cancer treatments can slash platelet numbers, leading to a condition called thrombocytopenia and putting people at risk for internal bleeding.

Improved compensation, expanded mentorship and training opportunities, and concrete measures to improve workforce diversity are all needed to address attrition from the ranks of physician scientists specializing in infectious diseases, and to ensure that the next generation of that work force is sufficient to bring quests for new life-saving treatments and cures to fruition, according to recommendations released today by three medical societies.

Scientists at The University of Texas Health Science Center at Houston (UTHealth) have identified the brain networks that allow you to think of an object name and then verbalize that thought. The study appeared in the July issue of BRAIN. It represents a significant advance in the understanding of how the brain connects meaning to words and will help the planning of brain surgeries.
