A team of HHMI scientists has peered deep inside HIV-1 for a closer view of the fragile shell that envelops the virus' genetic material.
Dan Littman and fellow researchers have found a receptor for HIV that appears to play a key role in the transmission of the virus between individuals.
Michael Naski has helped to identify a genetic mutation that can cause bones to stop growing, leading to a form of dwarfism.
HHMI researchers have learned that basal cell carcinoma is caused by a defect in a gene that restrains cell growth.
HHMI scientists at the University of Texas Southwestern Medical Center are blocking the enzyme telomerase in a new strategy to prevent cancer cells from dividing.
Don Ganem's decision to search for a viral cause for Kaposi's sarcoma was considered risky by many molecular biologists.
Sharon Long's studies of signal transduction pathways in plants could yield insights into cancer and other diseases in humans.
Hughes researchers have developed a technique that may speed the identification of more tumor suppressor genes.
International research scholar Alec Jeffeys believes that radiation leaked from Chernobyl more than a decade ago may only now be manifesting its diastrous legacy.
Students at Texas Tech University are co-authors on a Nature paper showing a high rate of genetic change in rodents living near the Chernobyl reactor.
HHMI investigator Michael J. Welsh's research team has found that the airways of CF patients lack a natural substance that kills bacteria.
Hughes investigator Ronald D. Vale's research provides fresh insight into the structure and operation of the motor proteins that convert chemical energy in the cell into physical movement.
Experiments by Marc Caron and colleagues reveal the importance of the dopamine transporter in conditions such as addiction, schizophrenia and Parkinson's disease.
The discovery of a common genetic circuit for limb formation in arthropods is not only important for developmental biology, but also holds promise as an important new window to the past.
Genes and partial gene sequences are being found at a rate far faster than anyone can decipher their function. Two groups of Hughes researchers have been attacking that bottleneck with automated programs designed to shed light on the function of newly found genes and the expression patterns of known genes.
Peter S. Kim, an HHMI investigator at the Whitehead Institute for Biomedical Research, believes that the coiled-coil structure of a protein may provide HIV with the spike it needs to infect cells.
HHMI investigator Kevin P. Campbell, HHMI associate Franck Duclos and University of Iowa College of Medicine M.D./Ph.D. student Leland Lim have identified a new form of muscular dystrophy and developed a screening test to detect carriers of the disease.
Daniel E. Goldberg and colleagues have discovered how the malaria parasite is able to safely sidestep a poison in hemoglobin, its main food source.
HHMI Investigator Ronald M. Evans has found a new hormone that triggers cells to become fat cells.
A team of U.S. and Finnish scientists led by HHMI investigator, David Page, has found that a specific defect in the Y chromosome may be responsible for 13 percent of cases of azoospermia, the inability to make sperm and the most severe form of male infertility.
A research group headed by HHMI investigator Richard D. Palmiter at the University of Washington has shown conclusively that catecholamines are essential in mouse development, and most likely in human development, too.
Leptin administered to overweight mice during two weeks of treatment caused the mice to decrease food intake and increase energy expenditure.
A team of U.S. and Finnish scientists has found that a specific defect in the Y chromosome may be responsible for 13 percent of cases of azoospermia, the inability to make sperm and the most severe form of male infertility.
Christine and Jonathan Seidman have developed a mouse model of familial hypertrophic cardiomyopathy that should greatly enhance genetic studies of this deadly disease.
HHMI researchers at Rockefeller University have discovered a new hormone produced by fat tissue and presumably acting on the brain to regulate weight.
Scientists at the Howard Hughes Medical Institute at Columbia University are turning their attention to proteins that might beckon to the correct DNA target within human cells.
Researchers with the Howard Hughes Medical Institute at Yale University led a team that found the genetic cause at the heart of Liddle's syndrome.
Researchers at the Howard Hughes Medical Institute at the University of Utah have discovered two genes that cause long QT syndrome, an inherited disorder that causes sudden death in young, otherwise healthy people.
Yuet Wai Kan's team at the Howard Hughes Medical Institute at the University of California, San Francisco, has devised a method for delivering a genetic message to tissues and cells displaying the same molecular "address."
