With a collection of tools for rapidly processing changing visual cues, the eyes and brain work together to create meaningful images from raw signals.
Researchers have found the key factors that cause proteins to turn into sticky, fibrous clumps that can grind cellular activity to a halt.
Two groups of HHMI scientists working independently have identified a critical enzyme that allows a malaria-causing parasite to take over and thrive in human red blood cells.
Dos grupos de científicos del HHMI que trabajaban de forma independiente han identificado una enzima crítica que permite que el parásito que causa la malaria controle los glóbulos rojos sanguíneos humanos y prospere en el interior de los mismos.
Researchers have discovered that when DNA-copying machines run head-on into oncoming traffic, they kick the obstacles out of their way.
With the discovery of a sodium taste receptor, researchers have now identified the molecular receptors, cells, and coding logic for all five basic tastes.
HHMI researchers have developed a new method for growing human liver cells outside the body, which may boost efforts to develop a vaccine or treatment for hepatitis C infection.
Researchers have devised a new method that increases the number of blood vessel-forming cells they can make from human embryonic stem cells.
Investigadores han demostrado que distintas mutaciones que causan cáncer en células vecinas pueden cooperar para producir tumores.
Researchers have shown that distinct cancer-causing mutations in neighboring cells can cooperate to produce tumors.
Researchers have new information about how proteins called Argonautes bind to small RNAs and selectively shut down protein production.
Scientists have identified the genetic cause of a rare eye movement disorder and found that specific mutations in the disease gene can cause additional errors in neurodevelopment and neuronal survival.
A newly identified enzyme could help scientists create stem cells and arrest the growth of cancers by giving them the ability to wipe clean cells' developmental slates.
Terrible and swift as anthrax appears to its victims, the deadly toxin takes its time breaking into their cells. The entry of anthrax toxin into its cellular target is part of a carefully-planned, two-pronged attack, scientists have found.
Gerald M. Rubin, director of the Howard Hughes Medical Institute’s Janelia Farm Research Campus, will deliver a public lecture titled “The Fly Brain and Yours—Closer Than You Think,” at Janelia Farm in Ashburn, VA.
Janelia scientists have borrowed a technique from the field of astronomy to overcome biology’s equivalent of the twinkling of stars and the shimmering mirages in desert landscapes.
A small but aggressive fraction of metastatic cancer cells can re-infiltrate the original tumor, boosting its malignant potential.
Una fracción pequeña pero agresiva de células cancerígenas puede reinfiltrar el tumor original, aumentando su potencial maligno.
From the brain's point of view, not every itch is the same. HHMI researchers have identified a new type of itch receptor.
In a tour-de-force of evolutionary sleuthing, researchers have traced a yellow-to-black color change in African fruit flies to five single-letter genetic mutations.
Researchers have identified a naturally occurring human protein that helps prevent infection by H1N1 influenza and other viruses, including West Nile and dengue virus.
A newly identified gene mutation is one of only a handful of mutations outside the X chromosome to be linked to intellectual disability.
A new method for strengthening proteins could lead to improved laundry soap, better nanotechnology, and less expensive cancer drugs.
Comparing the DNA of fish with and without spiny pelvic hindfins provides evidence that evolution can leap rather than shuffle.
