Blood vessels in the lungs produce signals that activate the regeneration of alveoli—the tiny cavities through which blood takes in oxygen and releases carbon dioxide.
The fruit-fly protein Zelda helps govern the developmental handoff from mother's influence to an animal's own genome.
Fruit flies integrate smell and visual information to fine-tune flying behavior.
Seven HHMI investigators are among the 65 new members announced today.
At least 100 trillion bacteria live in the mammalian gut. How can we carry all those organisms and not get sick?
New HHMI research shows that reactivating fetal hemoglobin production in adult mice effectively reverses sickle cell disease.
Nueva investigación del HHMI muestra que la reactivación de la producción de hemoglobina fetal en ratones adultos revierte eficientemente la enfermedad de células falciformes.
HHMI scientists have identified a cellular pathway that may be key to sparking growth of pancreatic beta cells in mice and humans.
Neurobiologist Leslie Vosshall will discuss why mosquitoes bite some people and not others at a lecture on November 9. The event is free and open to the public.
New research pinpoints a biological barrier that has thus far slowed progress in creating disease-specific stem cell lines using a technique known as nuclear transfer.
Dietary folic acid helps prevent a subset of neurological birth defects in humans. Now, researchers have found that certain genetic mutations in mice that mimic these birth defects do not respond to a diet enriched with folic acid.
In the last 18 months, Janelia Farm has recruited two group leaders, four fellows and four junior fellows.
In one region of the human brain, new cells are generated only until 18 months of age.
Most of the neurons in the VNO, a sensory organ long assumed to be primarily devoted to pheromone detection, are dedicated to the detection of animals from other species.
A new study in fruit flies suggests that DEET confuses insects by jamming their odor receptors.
New studies highlight promising vaccine strategies to prevent malaria parasites from causing illness and death.
Horwich and Franz-Ulrich Hartl share the 2011 Albert Lasker Basic Medical Research Award for key discoveries that elucidate steps in protein folding.
Scientists have identified a genetic regulator that controls the reshuffling of gene segments in immune cells.
Beachy is being honored for his work on Hedgehog, a key molecule in development.
HHMI researchers have developed a potential TB vaccine that completely eliminates tuberculosis bacteria from infected tissues in some mice.
Distinct areas of the brain process sweet, bitter, salty, and umami tastes.
Designer ion channels that can turn neurons on or off will help researchers understand the connection between behavior and neural circuitry.
The first definitive proof of a weak spot in the parasite's apicoplasts—organelles with ancient plant origins—offers hope for drugs and vaccines against malaria.
New research has classified vertebrate evolution in relation to periods of evolution marked by changes in specific kinds of genes.
Protective chemicals known as interferons may identify themselves by how tightly they grip their receptor at various attachment points.
