Traditional "hunter-gatherer" and "horticulturalist" populations have significantly lower age-related increases in blood pressure and less risks of atherosclerosis than "modernized" populations. Lifestyle factors of these traditional populations -- high physical activity and high fruit and vegetable diets -- may protect against normal aging phenomena, high blood pressure and hardening of ...

Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as a traditional blood test in real-time, simply by shining a light through ...

Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device however, can reveal much the same information as a traditional blood test in real-time, simply by shining a light through the skin. This portable optical instrument is able ...

For the first time, scientists have shown that an experimental bariatric surgery can lower blood sugar levels in rats with type 1 diabetes.

A new study indicates a specific gene makes people more prone to developing Alzheimer's.

Genetic variants detectable in blood can signal that a woman is at risk of postnatal depression.

ApoE4, a well-known genetic risk factor for Alzheimer's disease triggers a cascade of signaling that ultimately results in leaky blood vessels in the brain, allowing toxic substances to pour into brain tissue in large amounts, scientists report.

Researchers have discovered a way of identifying which women are most at risk of postnatal depression (PND) by checking for specific genetic variants. The findings could lead to the development of a simple, accurate blood test which checks for the likelihood of developing the condition.

A compound called rutin, commonly found in fruits and vegetables and sold over the counter as a dietary supplement, has been shown to inhibit the formation of blood clots in an animal model of thrombosis.

A research team reports that mice in which an enzyme called histone deacetylase 3 was deleted had massively fatty livers, but lower blood sugar, and were thus protected from glucose intolerance and insulin resistance, the hallmark of diabetes.

Researchers have shown that levels of certain related proteins found in blood are associated with a greatly reduced risk for developing type 2 diabetes up to a decade or more later. The findings could open a new front in the war against diabetes.

His DNA has been decoded; samples from his stomach and intestines have allowed us to reconstruct his very last meal. The circumstances of his violent death appear to have been explained. However, what had, at least thus far, eluded the scientists, was identifying any traces of blood in Ötzi, the ...
