When X-linked genes evade silencing on the “inactive” chromosome in XX cells, some protect women from diseases such as cancer, but others seem to promote conditions such as autoimmunity.
The genetically modified bacteria spark an RNAi response in the parasite that leads to self-destruction—and perhaps a path to combatting colony collapse disorder.
Trophoblasts, collected from the mother during a blood draw, can determine fetal genetic abnormalities currently diagnosed through amniocentesis or chorionic villi sampling.
Suppressing the natural age-related increase in neuronal excitation lengthens the lives of worms, and there are indications that the same may be true for mice and humans.
Physical activity, independent of diet, shifts the composition of bacteria in the intestines, spurring researchers to search for species that might provide benefits akin to working out.
The genes promote the migration of endothelial cells outside of the uterus, a characteristic of both endometriosis and endometrial cancers, a study of mice and human tissue finds.
An Israeli lunar lander carrying the tiny animals crashed into the moon in April, and now scientists are trying to determine if the creatures are still alive.
