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.
Using advanced electron-microscopy and modeling techniques, a team of researchers has determined the structure of a eukaryotic ribosome with unprecedented accuracy.
Scientists have discovered a new type of stem cell in the skin that acts surprisingly like certain stem cells found in embryos: both can generate fat, bone, cartilage, and even nerve cells. These newly-described dermal stem cells may one day prove useful for treating neurological disorders and persistent wounds, such as diabetic ulcers.
HHMI researchers have identified a new factor necessary for the development of medulloblastomas, the most common type of malignant childhood brain cancer.
A protein found in the saliva of ticks may prove to be an attractive target for a new type of Lyme disease vaccine.
Scientists have found that preeclampsia can dramatically increase the likelihood that a woman will experience low thyroid function later in life.
Researchers have developed a new imaging method to track how a person’s brain divides up duties between the two halves.
A new imaging tool lets researchers watch individual neurons in the brains of living animals light up as they work together to control the animal’s behavior.
Scientists have an ambitious new strategy for untangling the evolutionary history of humans and their biological relatives: obtain, preserve, and sequence the DNA of approximately one species for each genus of living mammals, birds, reptiles, amphibians, and fish.
