May 15, 2014 — A bias toward using male lab animals and tissue samples from males may be limiting the effectiveness of medical research, according to top officials at NIH. They'll roll out new guidelines this fall.
Dec 3, 2013 — Brown tree snakes came to Guam aboard ships and planes decades ago. Since then, they've devastated the local bird population. Federal researchers continue to experiment with a unique way to kill the invaders: Drop mice laced with poison into the trees where the snakes hang out.
Oct 10, 2013 — A lack of funding to labs is likely to mean an early death for thousands of mice used in scientific and medical research. The loss of specialty mice, many of which have genes that can cause them to develop versions of human diseases, is especially troubling to scientists — and expensive.
Mar 7, 2013 — For more than a century, neurons have been the superstars of the brain. Now researchers say that when they placed human versions of another type of brain cell into mice brains, the mice grew up to be faster learners. This supports the hypothesis that these glial cells — and not just better-known neurons — play an important role in learning.
Feb 22, 2013 — The idea is that brown tree snakes will eat these snacks from the sky. Then, it's hoped, the snakes will die because the mice will be laced with painkillers. The active ingredient in those drugs should be toxic to the snakes.
