HHMI investigators have found a gene that determines whether roundworms prefer to eat alone or in a group. Further studies may give a glimpse at the genetic origins of social behavior.
HHMI researchers are making fundamental advances in understanding how genes control the shape and spatial orientation of organs.
Scientists have uncovered a critical mechanism by which light resets the biological clock in flies. This finding could lead to new treatments for jet lag and improved therapies for mood and sleep disorders.
HHMI researchers have used a fragment of HIV to deliver proteins into the cells of living mice.
Two related proteins that act as brakes for a variety of cellular growth processes appear to play a critical role in ensuring that both blood cells and immune system cells are neither overactive nor overabundant.
Teen tackles English, scores a Rhodes Scholarship. Grants in Action.
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.
HHMI researchers believe their technique can be used to determine the function of all of the fruit fly's genes.
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.
Cancer research captivates high schooler in HHMI-funded Student and Teacher Program at NIH. Grants in Action

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.
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.
Laura Poling unfazed by the sudden attention on the controversy around an article published in the February 12, 1999 issue of the journal Science, which challenges the fossil record by concluding that turtles, not birds, are the closest living relatives of crocodiles.
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.
