Major Alzheimer's risk factor linked to red wine target
The major genetic risk factor for Alzheimer’s disease (AD), present in about two-thirds of people who develop the disease, is ApoE4, the cholesterol-carrying protein that about a quarter of us are born with. But one of the unsolved mysteries of AD is how ApoE4 causes the risk for the disease.

Scientist uncovers internal clock able to measure age of most human tissues; Women's breast tissue ages faster than rest of body
A new study is the first to identify a biological clock able to gauge the age of most human tissues. Some parts of the anatomy, like a woman’s breasts, age faster than the rest of the body.
