Interferon cures only 20 percent of patients infected with hepatitis C virus. HHMI researchers may know the reason why.
Complex mathematical analysis reveals how potassium is allowed to travel across the cell membrane.
Sons conceived with the aid of a popular in vitro fertilization technique carry same genetic mutations that rendered their fathers infertile.
Molecular studies of a family of genes are pruning branches from the old evolutionary tree.
Genetic studies confirm that one gene mutation plays a major role in inherited deafness; the importance of another genetic mutation is called into question.
HHMI researchers discover a gene responsible for triggering embryonic cells in the inner ear to develop into sound- and motion-sensing hair cells.
HHMI researchers have found a protein whose activity controls the shape of a developing organ.
HHMI researchers have discovered a molecule that resembles a component of snake toxins, but has a dramatically different effect on the nervous system.
Research to improve vaccines for infectious diseases must move forward. At the same time, according to HHMI investigator Barry Bloom, scientists should be perfecting vaccines that tackle pathogens associated with other diseases, such as cancer and heart disease.
Nitric oxide prevents programmed cell death by handcuffing the molecular executioner.
