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.

Biologists in Arts & Sciences have mapped the crystal structure of a key protein that makes the metabolites responsible for the bitter taste in cruciferous plants like mustard and broccoli. The results could be used along with ongoing breeding strategies to manipulate crop plants for nutritional and taste benefits.

Researchers at Washington University in St. Louis have developed a one-parameter measure that makes selecting the correct electrolyte for potassium-air batteries an exercise in rationality, rather than patience.

Even in the strange world of open quantum systems, the arrow of time points steadily forward — most of the time. A video details new experiments conducted at Washington University in St. Louis that compare the forward and reverse trajectories of superconducting circuits called qubits, and find that they largely tend to follow the second law of thermodynamics. The research is published July 9 in the journal Physical Review Letters.

As ecosystem engineers, bison have been hiding in plain sight for the past 40 years, since archaeologists first discovered that several native plants were domesticated in eastern North America. New research by Natalie Mueller, assistant professor of anthropology in Arts & Sciences, explains the connection, published July 8 in Nature Plants.

New research from Washington University in St. Louis provides compelling evidence that magmas may be wetter than once thought. The work led by experimental geochemists including Michael J. Krawczynski in Arts & Sciences is published in the July 2 issue of the journal American Mineralogist.

Research from the McKelvey School of Engineering suggests that without considering certain factors, researchers may overestimate how fast calcium carbonate forms in saline environments.

A team involving a doctor and five undergraduate students – three from the McKelvey School of Engineering – recently took first place in the 2019 Discovery Competition.

Dropwise condensation on liquid infused surfaces presented a mystery: what’s causing the movement of water droplets? Researchers in the McKelvey School of Engineering have found the answer.
