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 ...

When scientists opened the doors of a research facility and let carefully bred lab mice loose into a fenced field, they expected skittish, fragile animals to struggle. Instead, the mice rapidly shed ...

In a new study, researchers have found that mice can instinctively exhibit rescue-like behavior toward anesthetized conspecifics—without any prior training or external rewards. The study, published in ...

Researchers corrected the expression of a single overactive gene in the amygdala of mice and reversed anxiety, ...

University of California, Los Angeles, researchers have identified neural mechanisms behind prosocial behaviors in mice directed toward unresponsive conspecifics. Their findings suggest that mice, ...

Pheromones—chemicals produced by animals—are well-known for influencing the social and sexual behavior of members of the same species. These chemical signals convey vital information, such as gender ...

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