A painting of museum specimens of Bachman's warbler. The extinct songbird was a distinct species, and not a hybrid of two closely related living species, according to a new study in which the full genomes of seven museum specimens of the bird were sequenced. A paper describing the study, led by Penn State researchers, highlights the crucial role that museum collections can play in science.

Most calves stand at birth or shortly after, like the healthy calf in this photo. The condition now known as calf recumbency results in animals too weak to stand at birth or shortly after, and most did not survive beyond six weeks of age. Chad Dechow, Penn State associate professor of dairy cattle genetics, conducted a genome-wide association using thousands of DNA markers and pedigree analysis to determine the genetic origin for recumbency.

A new study led by researchers at Penn State reveals that populations of Masai giraffes separated geographically by the Great Rift Valley have not exchanged genetic material in more than a thousand years, and in some cases hundreds of thousands of years, suggesting these giraffes are more endangered than previously thought.
