Geologists revisit the Great Oxygenation Event
Recent work with geochemical proxies for oxygen levels suggests that oxygen levels continued to fluctuate long after the Great Oxygenation Event 2.7 billion years ago, and that the oceans were many different flavors of anoxic right up until the Edicaran period, 600 million years ago. What happened in the intervening 2 billion years will be contested until scientists have more data, says a geochemist at Washington University in St. Louis.
Dining with laureates
In mid-summer two lucky Washington University in St. Louis graduate students got to travel to Lake Constance in Germany to listen in the morning to Nobel laureates lecture on the topics of their choice and quiz them in afternoon about life in science and what it is really like.
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.
Couch potatoes of the animal kingdom
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

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.
