The 14,000-year-old record raises a very troubling question about where seabirds in the South Atlantic and Southern Ocean will go as the climate continues to warm.

The study published in Open Biology unravels important data for a better understanding of the process of division in stem cells and for the development of safer ways to use them in medicine.

A new study from the Cornell Lab of Ornithology confirms that most birds -- but not all -- synchronize their migratory movements with seasonal changes in vegetation greenness. This is the first study of its kind to cover the Western Hemisphere during the year-long life cycle of North American migratory birds that feed on vegetation, seeds, nectar, insects, or meat.

Butterflies have long captured our attention due to their amazing color diversity. But why are they so colorful? A new publication led by researchers from Sweden and Germany suggests that female influence butterfly color diversity by mating with colorful males.

A new paper in Behavioral Ecology finds that wild vampire bats that are sick spend less time near others from their community, which slows how quickly a disease will spread. The research team had previously seen this behavior in the lab, and used a field experiment to confirm it in the wild.

The critically endangered vaquita has survived in low numbers in its native Gulf of California for hundreds of thousands of years, a new genetic analysis has found. The study found little sign of inbreeding or other risks often associated with small populations.

Serotonin can act as a growth factor for the stem cells in the fetal human brain that determine brain size.
