David Kilper / WUSTL PhotoWUSTL researchers are trying to infer the Egyptian climate from the fossil evidence.Earth and planetary scientists at Washington University in St. Louis are studying snail fossils to understand the climate of northern Africa 130,000 years ago. While that might sound a bit like relying on wooly bear caterpillars to predict the severity of winter, the snails actually reveal clues about the climate and environment of western Egypt, lo those many years ago. They also could shed light on the possible role weather and climate played in the dispersal of humans “out of Africa” and into Europe and Asia.

Calm seas can turn deadly when tsunamis strike.Tens of thousands of people who perished in the Indonesia tsunami would be alive today had there been a warning system in place in the Indian Ocean basin similar to one in place for 40 years in the Pacific Ocean, says a seismologist at Washington University in St. Louis. Douglas A. Wiens, Ph.D., professor of earth and planetary sciences in Art & Sciences, says it’s unfortunate, but the catastrophic tragedy will be the catalyst for developing such a system, just as the 1964 Alaska tsunami event triggered the installment of the current Pacific Ocean system.”

Jupiter: a core of tar.After eleven months of politics, now it’s time for some real “core values” – not those of the candidates but those of the great gas giant planet, Jupiter. Katharina Lodders, Ph.D., Washington University in St. Louis research associate professor in Earth and Planetary Sciences in Arts & Sciences, studying data from the Galileo probe of Jupiter, proposes a new mechanism by which the planet formed 4.5 billion years ago.

Researchers have calculated that the precise isotopic structure of xenon in the sample reveals an operation that worked like a geyser.

Researchers Rosie Koch and Stan H. Braude won an award from the Animal Behavior Society of America for their documentary, All the Trappings.

“Experimental failure is a basic element of university life, and from the university perspective a failed spacecraft is not necessarily a failed mission,” Michael Swartwout said.

The bacterium Acetobacter aceti makes unusually acid-resistant enzymes in spades, which could open new doors in protein chemistry.

The agreement makes the software called ArcGIS available to all faculty, staff and students.

A chemist at Washington University in St. Louis has found surprisingly tough enzymes in a bacterium that “just says no to acid.” Acid resistance is a valued trait for both pills and human pathogens. The bacterium Acetobacter aceti makes unusually acid-resistant enzymes in spades, which could make the organism a source for new enzyme products and new directions in protein chemistry.
