Radioactive carbon-14 determines the number of fat cells remains constant in all body types

The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped researchers determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the actual number of fat cells.

Study finds darapladib lowers biomarker for cardiovascular problems

Despite widespread use of cholesterol-lowering drugs, a significant number of cardiac patients continue to suffer heart attacks and stroke.

The drug darapladib may offer a way to fight that risk, according to new research led by the University of Pennsylvania School of Medicine.
