What happens when scientists start changing the brain—the very system through which an animal's mental states are expressed in behavior?

Neuroscientists have made a major advance in modeling the human brain in mice, offering a new way to study conditions like ...

Lab-grown organoids wire into mice missing a key part of their brain, offering a new way to test drugs for developmental conditions. Human brain tissue transplanted into mice that lack a key part of ...

Researchers found that gut-derived GLP-1 and GLP-2 signaling helped protect mice against T cell-induced intestinal injury, with GLP-1R primarily regulating inflammation and GLP-2R supporting ...

Are mice clever enough to be strategic? Kishore Kuchibhotla, a Johns Hopkins University neuroscientist who studies learning in humans and animals, and who has long worked with mice, wondered why ...

Mice are the most common animal used in research. Many routine procedures (including blood pressure measurement, injections, and blood collection) require the mouse to be restrained. As manual ...

Staff expects it will take a long time to find families for all of the animals. But, experts said, it likely didn’t take the mice long to multiply given just how quickly they reproduce STRATHAM, N.H. ...
