ALS: How ‘toxic’ proteins could protect neurons

ALS: How ‘toxic’ proteins could protect neurons

Researchers have now investigated the mechanisms of a protein called SOD1 that is known to play a role in amyotrophic lateral sclerosis, and they uncovered some surprising findings. Researchers suggest that proteins thought to destroy neurons in people with ALS may actually have the opposite effect. The scientists found that while small aggregates of SOD1 […]

Sitting harms brain health, regardless of exercise

Sitting harms brain health, regardless of exercise

Too much sitting may not be good for the brain, according to a preliminary study of adults who have reached middle age and beyond. Among middle-aged and older people, prolonged sitting may harm the brain. Researchers from the University of California, Los Angeles (UCLA) discovered that among 35 adults aged 45–75 without dementia, those who […]

How the brain’s ‘immune memory’ may lead to Alzheimer’s

How the brain’s ‘immune memory’ may lead to Alzheimer’s

A new study shows that microglia, which are the immune cells of the central nervous system, can “remember” inflammation. This “memory” influences how the cells react to new stimuli and deal with toxic plaque in the brain, a marker of Alzheimer’s disease. The brain’s immune cells remember previous inflammation. Microglia, sometimes referred to as “scavenger” […]

‘Mutant ferrets’ shine a light on human brain evolution

‘Mutant ferrets’ shine a light on human brain evolution

While exploring human brain development using a mutant ferret model, scientists accidentally stumbled upon clues as to the evolution of our oversized brains. Genetically altering ferrets gives new insight into brain development and evolution. Humans are blessed with relatively large brains. And, during the past 7 million years — a short time span in evolutionary […]

Being a ‘night owl’ could kill you, study finds

I wake up at 5.15 a.m. each day to get to work on time, so going to bed at a reasonable hour is a must for me. According to new research, it’s also beneficial to my health; scientists found that “night owls” have a higher risk of early death. Researchers find that being a night […]

Just one night of bad sleep increases Alzheimer’s protein

Just one night of bad sleep increases Alzheimer’s protein

If you think that a bad night’s sleep is harmless, think again. New research suggests that a single night of sleep deprivation can increase levels of a protein involved in Alzheimer’s disease. Researchers reveal that just one night of sleep deprivation can increase levels of beta-amyloid protein. Scientists from the National Institute on Alcohol Abuse […]
