Report: 160 genes linked to brain shrinkage in study of 45,000 adults
A new study implicates 160 genes in brain shrinkage seen on MRIs of 45,000 healthy adults. The shrinkage is in the cortex, the dimply outer layer of the brain that gives rise to thinking,...
Study: Receptor makes mice strong and slim
Increasing abdominal girth and shrinking muscles are two common side effects of aging. Researchers at the University of Bonn have discovered a receptor in mice that regulates both effects. Experiments with human cell cultures...
Study: Alcohol, drugs ‘make isolation worse’

Study: Thyroid inflammation linked to anxiety disorders
Patients with autoimmune inflammation of their thyroid may be at greater risk of developing anxiety, according to a study being presented at e-ECE 2020. The study found that people with anxiety may also have...
Study: Using sponges to wipe out cancer
A sponge found in Manado Bay, Indonesia, makes a molecule called manzamine A, which stops the growth of cervical cancer cells, according to a recent publication in the Journal of Natural Products submitted by...
Researchers identify gene linked to thinness that may help resist weight gain
While others may be dieting and hitting the gym hard to stay in shape, some people stay slim effortlessly no matter what they eat. In a study publishing May 21 in the journal Cell,...
Study: One-time treatment generates new neurons, eliminates Parkinson’s disease in mice
Xiang-Dong Fu, PhD, has never been more excited about something in his entire career. He has long studied the basic biology of RNA, a genetic cousin of DNA, and the proteins that bind it....
New imaging tool helps scientists see extent of Alzheimer’s early damage
New imaging technology allows scientists to see the widespread loss of brain synapses in early stages of Alzheimer’s disease, a finding that one day may help aid in drug development, according to a new...
Research helps to settle debate on roles of REM and non-REM sleep in visual...
Which sleep stage is most important for learning: REM or non-REM? Does sleep improve learning by enhancing skills while people snooze, or by cementing those skills in the brain so that they're less likely...
Study: New technology will show how RNA regulates gene activity
The discovery of a huge number of long non-protein coding RNAs, aka lncRNAs, in the mammalian genome was a major surprise of the recent large-scale genomics projects. An international team including a bioinformatician from...
