The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Mental health conditions could accelerate cardiovascular risk in young and middle-aged women

Younger women are generally thought to have a low risk of heart disease, but new research urges clinicians to revisit that assumption, especially for women who suffer from certain mental health conditions.

Study finds changing trends in arterial disease risk among diabetics

There has been a redistribution in the risk of arterial disease in type 1 and 2 diabetes. The risks of heart attack and stroke have decreased significantly, while complications in more peripheral vessels have increased in relative importance, according to studies at the University of Gothenburg.

DNA damage in neurons crucial for creating stable memories

Just as you can't make an omelet without breaking eggs, scientists at Albert Einstein College of Medicine have found that you can't make long-term memories without DNA damage and brain inflammation. Their surprising findings were published online today in the journal Nature.
