Peter P. Gaspar, professor emeritus of chemistry in Arts & Sciences at Washington University in St. Louis, died Saturday, July 27, 2019, in St. Louis, following a long illness. He was 84.

Research from Washington University in St. Louis finds that mutations of a gene implicated in long QT syndrome in humans may trigger seizures because of their direct effects on certain classes of neurons in the brain — independent from what the genetic mutations do to heart function. The new work from Arts & Sciences was conducted with fruit flies and is published August 8 in PLOS Genetics.

A long-term study of western gorillas in Gabon has revealed an unexpected behavior: they use their teeth to crack open and eat nuts. New research by Adam van Casteren, lecturer in biological anthropology in Arts & Sciences, may have important implications for the way researchers predict the diet of human ancestors based on the shape of their teeth.

Researchers from Arts & Sciences have solved the X-ray crystal structure of the enzyme that makes obafluorin — a broad spectrum antibiotic agent made by a fluorescent strain of soil bacteria. This new class of antibiotics might provide a powerful antidote to the growing scourge of antibiotic resistance.

Biologist Lucia Strader in Arts & Sciences discovered a cellular transporter that links two of the most powerful hormones in plant development — auxin and cytokinin — and shows how they regulate root initiation and progression. Understanding why and how plants make different types of root architectures can help develop plants that better cope with distinct soil conditions and environments.

John Paul Stevens of the U.S. Supreme Court passed away on July 16, 2019. Greg Magarian, the Thomas and Karole Green Professor of Law, served as a justice clerk for Stevens and offers this remembrance.

Humans have already learned much from the very first moon samples collected by the Apollo program astronauts. As NASA plans for its next manned mission by 2024, a leading lunar expert shares his science priorities for the return: “We need to learn how to live and work off Earth and beyond the low Earth orbit.”

A new study reveals much about the history of African poultry development, according to Helina S. Woldekiros, assistant professor of anthropology in Arts & Sciences. But a 3,000-year-old local breed type is threatened by the introduction of commercial cluckers.

Logging road construction in Western Equatorial Africa has accelerated over the last two decades and has led to a dramatic decline of intact forest lands in the region, according to new research published by Crickette Sanz, associate professor of biological anthropology in Arts & Sciences. Increased human immigration and degradation of natural resources follows in the wake of such road expansion.

Crickette Sanz, associate professor of biological anthropology in Arts & Sciences at Washington University in St. Louis, received the 2019 Ai’s Scarf Award, otherwise known as the Women-in-Primatology Award. The honor was announced in Kyoto, Japan, in advance of World Chimpanzee Day July 14, a celebration of “our closest cousin in the animal kingdom.”
