Researchers test mechanisms explaining differences in dengue serotype and disease severity by statistically fitting mathematical models to viral load data from dengue-infected individuals. They find a role for viral repl...

Scientists have discovered the hidden connections in our genomes that contribute to common diseases. Using a pioneering technique, the results are beginning to make biological sense of the mountains of genetic data linki...

Good cholesterol is well associated with lower cardiovascular disease risk, but just raising high-density lipoprotein (HDL) levels have produced disappointing results in recent clinical trials. A new study may explain wh...

Connective tissue cells in the heart turn into bone-producing cells in response to injury, researchers have found. The discovery helps explain why some people who survive heart damage develop abnormal calcium deposits--t...

When HIV attacks a T cell, it attaches itself to the cell's surface and launches a "harpoon" to create an opening to enter and infect the cells. To stop the invasion, researchers have developed genetically engineered T c...
