Monogamy is rare in mammals, but there’s a group that researchers widely consider to be socially monogamous: owl monkeys. However, a new study of these canopy-dwelling, nocturnal primates, which live in areas that stretch from Panama to Argentina, suggests that sometimes even long-bonded pairs endure break-ups that have consequences for their future reproductive success.

PHILADELPHIA — Breaking up is hard to do — and can be detrimental to one’s reproductive fitness, according to a new University of Pennsylvania study.

PHILADELPHIA — With a new insight into a model of Parkinson’s disease, researchers from the University of Pennsylvania School of Veterinary Medicine have identified a novel target for mitigating some of the disease’s toll on the brain.

After 125 years, Penn’s Mask and Wig club will once again honor its motto, “Justice to the stage and credit to the University,” with an original production that explores a time-traveling hero’s struggles to teach a society to value its members for more than their good looks.

In 1950, the University of Pennsylvania Museum of Archaeology and Anthropology sent scholars to a site in central Turkey, about 50 miles southwest of Ankara.

It may be cliché to say that everything on the planet is interconnected, but that doesn’t mean it isn’t true.

PHILADELPHIA — Though churning smokestacks, cud-chewing cows and gasoline-burning vehicles are contributing constantly to greenhouse gas emissions, there are also many processes that do the reverse, pulling molecules like carbon dioxide out of the atmosphere. One of these is chemical weathering, which occurs when rock turns into soil.

La’Toya Latney’s grandmother has a photo from when Latney was about 5 years old. In it, she is sitting in front of the television, transfixed by a nature program on grizzly bears hunting salmon swimming upstream. “At that time she said she knew I was going to be a veterinarian, so it’s been a long time coming for me,” says Latney.

The Turkish archaeological site of Gordion is best known for the “Midas Tomb”—a dome of earth built to house the remains of an ancient notable who, until recently, was believed to be Phyrgian King Midas, famed for his wealth.

Many people come to the University of Pennsylvania Museum of Archaeology and Anthropology to be wowed by the Lower Egyptian gallery’s towering sphinx. Or they may head to the Upper Egyptian gallery, where the preserved remains of mummies never fail to fascinate.
