The body's immune system can use a surprisingly common molecule to recognize prostate tumors.
New research has found that many of the symptoms of fragile X syndrome can be eliminated in mice by reducing the expression of a single gene.
Researchers have a new picture of how neurons forge physical connections between one another in order to communicate.
New research shows that normal aging appears to disrupt communication between different regions of the brain.
The antidepressant mianserin can extend the lifespan of the the roundworm by about 30 percent.
Researchers have deciphered the molecular language that cholera bacteria use to coordinate their infectivity. By interrupting the bacterium's chemical conversation, researchers may be able to stop cholera virulence.
Scientists have shown how odor-sensing neurons in the worm can activate or inhibit other neurons that control crawling and turning.
A worldwide network of more than 150,000 home computer users helped HHMI researchers predict the structure of a small, naturally occurring protein.
In mending the DNA broken during antibody production, immune cells can employ a type of DNA repair that is fundamentally different than the classical method.
A new delivery vehicle for transplanted islet cells may help clinicians track the cells once they are inside the body.
Laboratory experiments have enabled researchers to bypass half a billion years of evolution, giving one protein the ability to function like a distantly related protein with just a few simple changes.
Genetic analysis of a year's worth baby poop has given researchers a detailed picture of how bacteria come and go in the intestinal tract.
An HHMI professor has teamed up with the Posse Foundation to develop a bold plan to equip inner-city high school students to succeed in the sciences.
HHMI scientists have discovered that microRNAs can also shut down the proliferation of cancer cells.
Studies in mice show that lithium can ease the symptoms of spinocerebellar ataxia type 1, an inherited neurodegenerative disorder.

HHMI will hold a national competition for investigators and plans to name as many as 50 new researchers by spring 2008.
Researchers have developed a fruitfly model that replicates the genetic instability seen in a variety of neurodegenerative diseases.
A protein that captures light in ocean-dwelling bacteria puts light's energy to work inside cells.
Researchers have learned how the immune system slices and dices genes so B cells can program antibodies to seek out and destroy invaders.
Two HHMI research teams have discovered new information about how the botulinum neurotoxin shuts down neurons with deadly efficiency.
P[acman], a new tool for inserting large genes into precise locations on the chromosome, may enable researchers to overcome challenges in pinning down the function of genes.
Here is a list of research institutions that qualify for the 2007 competition.
HHMI announces new national competition to appoint outstanding physician-scientists as HHMI investigators. The Institute expects to select approximately 15 new researchers by Fall 2007 and is committing approximately $200 million to their first term of appointment.
Some infectious diseases might run in families because susceptibility to them is inherited.
