Lots of lead in the water? Maybe manganese is to blame
In the right environment, a harmless mineral can do a lot to change the composition of the drinking water that flows through lead pipes. New research from the McKelvey School of Engineering discovers how.
WashU Expert: On Apollo legacy, and why we should return to the moon
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.”
Putting the brakes on lateral root development
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.
Genes linked to death from sepsis ID’d in mice
Bacteria in the bloodstream can trigger an overwhelming immune response that causes sepsis, a life-threatening condition. Now, researchers at Washington University School of Medicine in St. Louis have found genes that help protect the body’s cells from dying during sepsis, which could lead to new treatments.
More cancer patients get help to quit smoking
A new program funded through the Cancer Moonshot Initiative has doubled the number of patients at Siteman Cancer Center assessed for smoking — and increased by fivefold the percentage of cancer patients who smoke now taking medication to help them quit. The results have been published in the journal Translational Behavioral Medicine.
Long live the long-limbed African chicken
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.
Northern Congo declining under logging pressure
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.
Mustering a milder mustard
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.
