The mitochondrial genome, long thought to be nearly identical in every cell in the human body, actually varies to a surprising degree.
At the AAAS Annual Meeting, David Anderson discussed how studies of model organisms such as mice and fruit flies can improve scientists' understanding of the neural basis of emotion.
At the AAAS Annual Meeting on Feb. 20, Owen Witte discussed a new tool to understand how cancers grow—and with it a new opportunity to identify novel cancer drugs.
At the AAAS Annual Meeting on Feb. 20, George Daley described the current climate facing stem cell researchers in the United States.
In their report "Scientific Foundations for Future Physicians"—discussed Feb. 19 at the AAAS Annual Meeting—the AAMC and HHMI challenge colleges and universities to seize the opportunity to make premedical and medical education more interactive and interdisciplinary.
Researchers have created a group of stem cells from patients who have a disorder that causes accelerated aging and bone marrow failure. Using a genetic reprogramming technique to “turn back the molecular clock” in these cells appears to reset the cells and reverses rapid aging.
A new vaccine tested in 100 West African children triggers the immune system to produce antibodies against the malaria parasite at levels normally seen only in adults who have strong resistance to the disease.
Una nueva vacuna que se probó en 100 niños de África Occidental hizo que el sistema inmune produjera anticuerpos contra el parásito de la malaria en niveles que normalmente sólo se observan en adultos que tienen una fuerte resistencia a la enfermedad.
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.
The BBVA Foundation honors HHMI investigator Robert Lefkowitz for research on G protein-coupled receptors.
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.
