Neurons Help Flush Waste out of Brain during Sleep

Researchers at Washington University School of Medicine in St. Louis have found that brain cell activity during sleep is responsible for propelling fluid into, through and out of the brain, cleaning it of debris.

Researchers have found that brain cell activity during sleep is responsible for propelling fluid into, through and out of the brain, cleaning it of debris. Findings could lead to new approaches for Alzheimer’s, other neurological conditions.

There lies a paradox in sleep. Its apparent tranquility juxtaposes with the brain’s bustling activity. The night is still, but the brain is far from dormant. During sleep, brain cells produce bursts of electrical pulses that cumulate into rhythmic waves — a sign of heightened brain cell function.

But why is the brain active when we a...

US Patient ‘Happy Again’ after Brain Implant Treats Epilepsy and OCD

Dr. Ahmed Raslan, professor of neurological surgery, talks about the placement of a brain implant with patient Amber Pearson.

American Amber Pearson used to wash her hands until they bled, terrified by the idea of contamination from everyday items, a debilitating result of her obsessive compulsive disorder (OCD).

But the repetitive rituals of her condition are largely consigned to memory, thanks to a revolutionary brain implant that is being used to treat both her epilepsy and her OCD.

“I’m actually present in my daily life and that’s incredible,” the 34-year-old told AFP.

“Before, I was just constantly in my head worrying about my compulsions.”

Brain implants have hit the headlines recently with Elon Musk’s announcement that his Neuralink company had placed a chip in a pat...

Brain Boosters from Exercise and Diet

Studies show that physical activity is actually a mental health exercise. One article that states just 15 minutes of walking, especially in the out-of-doors, can boost mood and reduce feelings of depression.

People seem to think more clearly after a brisk walk as well. It makes sense. As the heart pumps oxygen and nutrients to working muscles, the brain gets the same benefits.

Are there foods that might help our brains stay focused?
In 2015, scientists reported on a diet that was found to help slow the gradual decline in cognitive function we may experience as we age...

Researchers leverage AI to Develop Early Diagnostic Test for Ovarian Cancer

For over three decades, a highly accurate early diagnostic test for ovarian cancer has eluded physicians. Now, scientists in the Georgia Tech Integrated Cancer Research Center (ICRC) have combined machine learning with information on blood metabolites to develop a new test able to detect ovarian cancer with 93 percent accuracy among samples from the team’s study group.

John McDonald, professor emeritus in the School of Biological Sciences, founding director of the ICRC, and the study’s corresponding author, explains that the new test’s accuracy is better in detecting ovarian cancer than existing tests for women clinically classified as normal, with a particular improvement in detecting early-stage ovarian d...
