HHMI researchers have found the first hereditary human sleep disorder that is caused by a single gene. The disorder is passed from generation to generation in the same simple pattern characteristic of traits such as eye color.
A team of biologists has determined the three-dimensional structure of an enzyme that allows certain bacteria to resist the killing effects of the antibiotic gentamicin. The structure is also shared by a number of proteins involved in basic biological processes, including circadian rhythms and gene regulation.
A genetic mutation common in the most severe forms of muscular dystrophy also predisposes to heart damage.
Two genes that generate the immune system's remarkable diversity are controlled by the same small piece of DNA.
Mice born without a gene that regulates appetite exhibit unexpected attacks of narcolepsy.
A two-tiered boost to the immune system may allow the body to better fight cancer on its own.

New theories about how neural activity and visual stimuli sculpt the developing visual system.
VectorNet enables students and teachers to analyze their own DNA sequences and DNA sequences from the Human Genome Project, which are posted in databases on the Internet.
Medical schools and research institutions in 24 states will receive $12.7 million in grants from HHMI to enrich science education in local schools and help attract a broad range of students to biomedical careers.
Several leading biomedical research institutions are proving that researchers and teachers working together can make science come alive for precollege students.
How do you bring science to life for youngsters and their teachers? The University of Mississippi School of Medicine does it by pairing them with real researchers.
A newly discovered protein in nerve cells holds enzymes poised for action next to their receptor.

Sons conceived with the aid of a popular in vitro fertilization technique carry same genetic mutations that rendered their fathers infertile.
HHMI announces the 1999 awards for graduate education and medical student research training fellowships.
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 invites colleges, universities to compete for $48 million to enrich undergraduate science education.
HHMI researchers have discovered a molecule that resembles a component of snake toxins, but has a dramatically different effect on the nervous system.
