Is race a biological category? How does race figure into scientific research, clinical practice, and the development and use of biotechnology and pharmaceuticals? And what can we learn from historical investigations into race that will inform today’s scientific and medical inquiries?

As soon as an infant cuts that first tooth, proper dental hygiene is a must. Babies who are put to bed with their bottles and toddlers who tote around sippy cups full of sugary juice all day are at risk of developing a condition called early childhood caries.

Patients with leukocyte adhesion deficiency, or LAD, suffer from frequent bacterial infections, including the severe gum disease known as periodontitis. These patients often lose their teeth early in life.

Eduardo Fernandez-Duque, an associate professor in the Department of Anthropology in Penn Arts & Sciences, has been studying owl monkeys in Argentina for nearly 20 years.

Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.

True monogamy is rare in the animal kingdom. Even in species that appear to “mate for life,” genetic maternity and paternity tests have revealed that philandering often takes place.

Early childhood caries involve a highly aggressive and painful form of tooth decay that frequently occurs in preschool children, especially those who come from backgrounds of poverty. The resulting decay can become so severe that treatment frequently requires surgery.

Babies are born with the ability to digest lactose, the sugar found in milk, but most humans lose this ability after infancy because of declining levels of the lactose-digesting enzyme lactase.
