  Everyone is familiar with pain, but no one fully understands its underlying molecular mechanisms. Scientists at King’s College, London, are doing something about that. In a recent study they found that life style and environmental factors that affect the epigenome, such as diet, smoking, drinking and exposure to pollution, might also alter a person’s sensitivity...

The quality of white matter in the brain may have an impact on an individual’s ability to excel at addition and multiplying, according to a new study. The white matter in the brain performs as a protectant sheath around neural pathways made up of gray cells, or gray matter. The neural pathways are like bundles...

The human brain stands out from that of all other species by facilitating cognitive tasks that other species are not able to achieve. The human brain weighs about three pounds -- a gigantic size relative to the body. Scientists have long believed that the large size of the human brain and our powerful minds are...

Technology has continued to improve the effectiveness of prosthetics over the years, making it easier for those who have lost limbs to lead more normal lives by being able to grasp objects in much the same way they would with their natural hand. The one detail that has always been missing, however, was the sense...

Some people who have had severe heart attacks, and most movie buffs, know the implications of the light many survivors of near-death experiences have seen. In spite of the belief by many that they have glimpsed the afterlife, it turns out that there is a scientific explanation for the phenomena. When blood flow stops, the...

Measurements taken to reduce lead exposure may already be helping to prevent children today from having Alzheimer’s later in life. A study that took place over a 23 year time span showed that monkeys who drank a formula rich in lead while they were infants later developed the tangles of tau, a key brain protein...
