Ancient DNA identifies donkey ancestors, people who domesticated them

Genetic investigators, include Fiona Marshall, PhD, professor of anthropology in Arts & Sciences, say that the partnership between people and the ancestors of today’s donkeys was sealed not by monarchs trying to establish kingdoms, but by mobile, pastoral people who had to recruit animals to help them survive the harsh Saharan landscape in northern Africa more than 5,000 years ago.

Pass the chips and hand over the remote. In a study involving the first-ever daily energy expenditure measurements in apes, a researcher from Washington University in St. Louis and his team have determined that orangutans living in a large indoor/outdoor habitat used less energy, relative to body mass, than nearly any eutherian mammal ever measured, including sedentary humans.

Enrichment with a purpose

University College students hang a fluorescent light fixture at the North Side Community School in St. Louis July 24 in a service project in conjunction with UCollege’s “Volunteer Resource Management” class. Students painted rooms, assembled furniture and hung boards and light fixtures. University College is holding a preview night for all its programs at 7 p.m. Thursday, Aug. 12, in Holmes Lounge.

Beware the smell of bitter almonds

Many food plants contain cyanogenic glycosides that can release cyanide when the food is eaten. What’s more, a greater proportion of food plants than plants in general are cyanogenic. WUSTL researcher Kenneth M. Olsen, PhD, offers an explanation of this toxic puzzle.

New Undergraduate Honors Program offered through University College

A new Undergraduate Honors Program will be offered beginning this fall semester at University College, the adult, evening and continuing education division in Arts & Sciences. The honors program offers high-achieving students the opportunity to join a learning community dedicated to an exceptionally rigorous but flexible program of study that enables students to work closely with a faculty mentor on an independent project and earn the distinction of Latin honors.

New bachelor of science in sustainability offered through University College

A new degree, the bachelor of science in sustainability, that provides an interdisciplinary approach to understanding and resolving today’s most pressing and complex environmental, economic and social challenges, has been developed at University College, the adult, evening and continuing education division in Arts & Sciences. The program, which will be offered beginning with the start of the semester Aug. 31, treats sustainable living from multiple perspectives — scientific, political, economic, social, historical, philosophical, anthropological and literary. 

Volvox genome sequenced

Scientists have sequenced the genome of the colonial alga, Volvox carteri, the journal Science announced. While the photosynthesizing colonial algae is fascinating in itself, knowing its genome may also help scientists engineer algae able to produce economic biofuels.
