Marijuana and hallucinogen use, binge drinking reached record highs in middle-aged adults, survey finds “Compared to non-users, marijuana users had 27% higher levels of iron in their blood,...
Aug 21 2023Reviewed by Lily Ramsey, LLM A breakthrough project mapping brain changes in nearly 1,300 people diagnosed with six different types of mental illness has revealed the extraordinary diversity of brain changes found in people with conditions like major depression and schizophrenia. The study, published in Nature Neuroscience and led by researchers at Monash University’s...
UNIVERSITY OF CALIFORNIA – SAN FRANCISCO Blood Factor Can Turn Back Time in the Aging Brain Platelets are behind the cognitive benefits of young blood, exercise and the longevity hormone klotho In a remarkable convergence, scientists have discovered that the same blood factor is responsible for the cognitive enhancement that results from young blood transfusion, the...

On the spot. The same thing can happen to people who need to concentrate on a challenging task. Now researchers have made a discovery that adds to our knowledge...
Jay Croft May 24, 2023 Using surgical implants inside the brain, scientists have recorded for the first time electrical patterns that occur when a person is feeling chronic pain, a new study in Nature Neuroscience concludes. The researchers used the devices on four patients who had felt endless nerve pain for more than a year. The devices recorded several times a...

June 19, 20235:01 AM ET In Huntington’s disease, proteins form toxic clumps that kill brain cells. Stowers Institute for Medical Research Diseases like Alzheimer’s, Parkinson’s, and Huntington’s are caused by toxic clumps of proteins that spread through the brain like a forest fire. Now scientists say they’ve figured out how the fire starts in at...
Common neurological disorders like depression and chronic pain can be challenging to treat with conventional methods. An automated version of a long-used brain stimulation technique holds real promise as a reliable and effective drug-free alternative. When discussing the brain, Risto Ilmoniemi has a striking habit: he points at his own. So, as he describes the relationship...
Reviewed by Danielle Ellis, B.Sc. May 31 2023 Acting as a team, twin stem cells activate the immune system to suppress tumor growth and prolong survival in representative preclinical models. Overall survival for patients with melanoma that has spread to the brain is only four to six months. Immunotherapies, which harness the power of the...
