Researchers mapped ear canal shape to body temperature to predict when ancestors of mammals first became endothermic.

A study finds that roots grow deeper than typical into southeastern pocket gophers tunnel networks, raising the possibility that the rodents cultivate their food.

The Scientist spoke to hyena researcher Eve Davidian for a broad look at power relationships between male and female mammals.

The discovery, made on the island of Sulawesi in Indonesia, constitutes an exceptionally high number of new mammals to be described in a single paper.

The mice, already known to regenerate skin, seem to avoid the tissue scarring that leads to organ failure in other animals.

Research in recent decades has explored how animals other than humans perceive different numbers of objects

A proof-of-concept study uses eDNA in the air to detect mammals, expanding the technique beyond aquatic sampling.

The use of pesticides has decreased in the US by more than 40 percent since 1992, but the emergence of more-potent chemicals means that they are far more damaging to many species.

In a new study, human and mouse cells recognized only one in five bacterial species collected from more than a mile below the Pacific Ocean’s surface.

The animals kill off around one-quarter of the neurons in their somatosensory cortex, perhaps to save energy, and the cells appear to return the following summer.

The Boston University professor, who died of complications related to COVID-19, spent more than 40 years researching the lives of bats.

Most small amphibious mammals have a diminished sense of smell, a quality that likely arose because of a tradeoff with thermoregulation capacities that allowed them to conserve heat in aquatic environments.

Thin strands tend to be stronger than thick ones.

An ancient animal’s hammer, anvil, and stirrup bones are at the base of the jaw but completely detached from it.

The silver-backed chevrotain was undetected for decades, but local reports have led researchers to document the species on camera.

The site, Corral Bluffs in Colorado, also reveals how plants evolved and how ecosystems rebounded after the asteroid impact.

Geography plays a role in how the small mammals adapt to environmental changes.

The agency plans to stop funding virtually all toxicology studies in mammals by 2035.

Researchers isolate roundworm DNA from animal excrement that is about 17,000 years old.
