mice

Scientists have taken another step toward understanding what makes the human brain unique.

An international team has identified a kind of brain cell that exists in people but not mice, the team reported Monday in the journal Nature Neuroscience.

The survival of a rare mouse considered crucial to the ecosystem of a north Florida island rests on the restoration of the coastal dune habitat destroyed by recent hurricanes.

20 Mice Hitch A Ride Into Space

SpaceX is set to launch a capsuled filled with supplies and science experiments to the International Space Station, including 20 lab mice.

Most potential new drugs fail when they're tested in people. These failures are not only a major disappointment, they sharply drive up the cost of developing new drugs.

A major reason for these failures is that most new drugs are first tested out in mice, rats or other animals. Often those animal studies show great promise.

But mice aren't simply furry little people, so these studies often lead science astray. Some scientists are now rethinking animal studies to make them more effective for human health.

Researchers have created mice that appear impervious to the lure of cocaine.

Even after the genetically engineered animals were given the drug repeatedly, they did not appear to crave it the way typical mice do, a team reports in Nature Neuroscience.

Editors' note: The study this story covers have retracted their work, saying that they made errors in conducting the experiment that invalidate the results. The study prompted controversy when it was published in 2013, and study author Douglas Melton collaborated with some of those critics to figure out where it went wrong.
