As a researcher, I still remember the discomfort I felt every time I had to sacrifice laboratory animals for an experiment. For decades, animals like mice, rats and pigs have been essential tools in ...
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 ...
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 ...
When you take the lab away, female mice are more likely to play, according to a new Cornell study. The study, published in the journal BMC Biology, took lab mice and placed them in large outdoor ...
In the world of biomedical research, the humble lab mouse is a superstar—it’s easy enough to rear in large quantities, shares a considerable amount of core biological processes with humans, and is ...

Lab mice that 'touch grass' are less anxious — and that highlights a big problem in rodent research
The online admonition to "touch grass" to soothe your emotional state may be backed by science — at least in lab mice. A recent study finds that mice that live outside are less anxious than those that ...
New research suggests that the commonly used ‘lab mouse’ may display behaviors entirely distinct from their wild-derived counterparts, prompting new considerations for the future of animal-based ...
In the wild, a mouse or rat leads a precarious life. In the city, they dodge traps, poisons, and broom-wielding humans. In the countryside, they face owls, shotguns, and more poison. As Australia’s ...
