Researchers have discovered a molecular master switch that triggers the genetic overhaul plants need to fight off pathogens.
The gene mutation that causes retinoblastoma changes the way cells turn on and off many other genes.
Researchers have discovered how plants regulate the development of the pores through which critical exchanges of water and carbon dioxide occur.
By resurrecting the ancient forms of a molecular machine, scientists have learned how simple evolutionary processes can produce the complex assemblies of molecules that allow modern cells to function.
New research shows that fluoride has dramatic effects on bacteria inside the mouth.
Scientists have pinpointed the gene responsible for a disease that causes seizures in infancy and sudden, uncontrollable movements in adolescence and early adulthood.
Studies of fragile X syndrome and tuberous sclerosis show that for brain cells to function normally, neural synapses must produce just the right amount of protein.
By activating regions of the brain linked to food-related pleasure, scientists are learning how the brain mediates the link between food preferences and hunger.
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.
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.
At least 100 trillion bacteria live in the mammalian gut. How can we carry all those organisms and not get sick?
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.
