When laboratory mice step out of their plastic cages and into real soil, their behavior changes so dramatically that it forces a rethink of what stress, health and even “normal” really mean. The story ...

Scientists stress out lab mice, a lot. Inducing chronic stress and anxiety in these furry critters is how scientists explore the bodily and cognitive effects of stress and discover anti-anxiety ...

Alzheimer’s disease has long been the nightmare diagnosis that medicine could slow at best, not stop. Now a wave of ...

In an experiment reminiscent of "Frankenstein," scientists found that rat brain cells can fill in for lost neurons in mice, even allowing the host rodents to sniff out sweets. While splicing rat and ...

It’s tiny, but this lab mouse could have a mammoth impact. With curly whiskers and wavy, light hair that grows three times longer than that of an ordinary lab mouse, the genetically modified rodent ...

New research suggests mice may exhibit revival-like behaviors to help unconscious mice recover faster. Lab mice may give 'first aid' to unconscious mates Li Zhang has anesthetized a lot of mice in his ...

Researchers have created genome-wide, high-resolution genetic maps of 100 inbred mouse strains. Compared with wild-derived strains, most of today's classical lab strains have limited genetic diversity ...

Li Zhang has anesthetized a lot of mice in his research career. Several years ago, the University of Southern California neuroscientist began noticing that sometimes, when he placed an anesthetized ...
