Astrocytes play major role in controlling sleep need

New animal research suggests that little-studied brain cells known as astrocytes are major players in controlling sleep need and may someday help humans go without sleep for longer without negative consequences such as mental fatigue and impaired physical health.

Anxious people use different part of brain for social behavior

When choosing their behavior in socially difficult situations, anxious people use a less suitable section of the forebrain than people who are not anxious.

Obesity impairs brain's ability to learn associations

To control our behavior, the brain must be able to form associations. This involves, for example, associating a neutral external stimulus with a consequence following the stimulus (e.g., the hotplate glows red - you can burn your hand).

Study provides insight into aging of the brain

Most of us who've reached middle age have noticed a slowing in memory and cognition, but scientists don't have a clear picture of the molecular changes that take place in the brain to cause it.

Klotho levels and telomere length may be associated through a coordinated downregulation of longevity factors

A new research paper was published by Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) in Volume 15, Issue 15, entitled, "Associations between klotho and telomere biology in high stress caregivers."

Deep learning-based AI model can estimate age from chest radiographs of healthy individuals

What if "looking your age" refers not to your face, but to your chest? Osaka Metropolitan University scientists have developed an advanced artificial intelligence (AI) model that utilizes chest radiographs to accurately estimate a patient's chronological age.

Gut microbiome variation linked to race and ethnicity arises after 3 months of age

Gut microbiome variation associated with race and ethnicity arises after three months of age and persists through childhood, according to a new study published August 17th in the open access journal PLOS Biology by Elizabeth K. Mallott of Washington University in St. Louis, US, Seth Bordenstein of Pennsylvania State University, US, and colleagues.
