Mapping lava tubes in the Galàpagos

Yearly expeditions to explore the lava tubes on the famed archipelago will culminate in an international symposium to be held there next year. In the meantime we may all be able to participate as well, if only vicariously. WUSTL’s Aaron Addison, who has traveled to the Galàpagos repeatedly to map the tubes, apppears in a new IMAX film called Galàpagos 3D. Not yet released in the United States, it stars David Attenborough as well as the archipelago’s fantastic geology and biology.

A meteorite mystery

A strange stone found in the Moroccan desert was the talk of the recent Lunar and Planetary Science Conference. The stone has highly unusual chemistry, suspiciously like that found by the Messenger space probe, which is currently surveying the surface of Mercury. If it was from Mercury, it would be the first meteorite from that body ever found. The prospects was thrilling but doubts crept in. WUSTL’s Randy Korotev, a lunar meteroite expert, explains the arguments for and against Mercurian origin.

Stardust in the laboratory the topic of 2013 McDonnell Distinguished Lecture

Thomas J. Bernatowicz,  professor of physics in Arts & Sciences, will deliver the McDonnell Distinguished Lecture at 7 p.m. Wednesday, April 10, in Room 105, Steinberg Hall, at Washington University in St. Louis. He will discuss what cosmic dust carried to Earth by meteorites has revealed about the creation of the elements by stars and supernovae. The St. Louis community is cordially invited to the lecture, which is sponsored by the McDonnell Center for the Space Sciences.

Avoid impulsive acts by imagining future benefits

Why is it so hard for some people to resist the least little temptation, while others seem to possess incredible patience, passing up immediate gratification for a greater long-term good? The answer, suggests a new study from Washington University in St. Louis, is that patient people focus on future rewards in a way that makes the waiting process seem much more pleasurable.

Painted turtle gets DNA decoded

Scientists have decoded the genome of the western painted turtle, one of the most abundant turtles on Earth, finding clues to their longevity and ability to survive without oxygen during long winters spent hibernating in ice-covered ponds.

Sussman to outline critical role of culture in understanding society

“The anthropological concept of culture is extremely important and often misunderstood because many of the things that are assumed to be biologically determined, like criminality or homosexuality or IQ, are really behaviorally and societally defined,” says WUSTL physical anthropologist Robert W. Sussman, and it forms the basis for his Phi Beta Kappa/Sigma Xi Lecture, “The Importance of the Concept of Culture to Science and Society,” the next Assembly Series program held at 4 p.m. Tuesday, April 9.

The secret lives of the wild asses of the Negev

The Asiatic wild ass (Equus hemionus) disappeared from the Negev, the desert region in southern Israel, in the 1920s. But a remnant herd survived in the Shah of Iran’s zoo. Some of these animals were reintroduced to the desert beginning in 1982. Recently scientists at Ben-Gurion University in Israel and Washington University in St. Louis have been inventing clever new ways to check on the status of these famously elusive animals.
