An evolutionary biologist is studying what these resilient urban pests can teach us about adaptation and evolution.

On a small, remote island in the Pacific Ocean, an unlikely predator feasts on the world’s largest albatross colony. Researchers are trying to figure out how to stop these murderous mice.

Clinical trial funders now insist studies use female participants. But it will still take a long time for our understanding of how medicine affects women to catch up.

Researchers found that female mice, despite ongoing hormonal fluctuations, exhibit exploratory behavior that is more stable than that of their male peers, countering the belief that the hormone cycle in females causes behavioral variation that could throw off results.

Rodents are the most numerous – and least studied – of all Earth’s mammals.

In a surprising finding, researchers have discovered that even though primates are "smarter" than mice, the rodents actually have more synapses per neuron.

Researchers are testing an antibody shot to protect people from Lyme disease-causing bacteria.

Studying mice shows that evolution often works on the same genes in different populations when they're confronted with similar environmental conditions.

Medical research to benefit people is first conducted in animals. Creating a new biomedical model by inserting human immune cells into pigs may lead to new insights and treatments.

Fungi are a small but important part of the gut microbiome. A new study in mice shows that how much weight mice gain on a processed food diet depends on this fungal microbiome.
