Further, these genetic variants affect each other,” explained one researcher.

During the uncrewed test, Orion traveled twice through the Van Allen belt, where it experienced periods of intense radiation, and reached an altitude of 3,600 miles above Earth. The spacecraft hit speeds of 20,000 mph and weathered temperatures approaching 4,000 degrees Fahrenheit as it entered Earth’s atmosphere.  less

The sixteen chapters bring to bear the power of 400,000 hours of teaching practice. Each chapter presents a unique teaching practice developed by an Einstein Fellow, the research in which the practice is grounded, and how the practice might be adapted for new learning environments.

The findings show that the world can be separated into seven regions for vectored human diseases -- diseases that are spread by pests, like mosquito-borne malaria -- and five regions for non-vectored diseases, like cholera.

Now, a study of genetic variation in HIV-1 and in the cells it infects has uncovered a chink in HIV-1's armor that may, at least in part, explain the puzzling difference -- and potentially open the door to new treatments.
