Douglas A. Wiens, Ph.D., professor of earth and planetary sciences in Arts & Sciences, and colleagues combined seismological and global positioning system (GPS) analyses to reveal two bursts of seismic waves from an ice stream in Antarctica every day, each one equivalent to a magnitude seven earthquake.

Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery.

Research is shedding new light on what happens in the brains of children and adults affected by clinical depression, anxiety disorders and schizophrenia, according to Washington University in St. Louis studies presented at a recent mental health symposium. The findings, which come as America celebrates Mental Health Awareness Month, point to new treatment options for preschool-aged children with significant clinical depression and for severely depressed adults who don’t respond to standard treatments, such as antidepressants and psychotherapy.

The massive earthquake that struck Sichuan province last week may have dealt a huge blow to China’s plans for a vast network of hydro-electric power dams, and the aftershock could mean more reliance on coal, more pollution and more competition for scarce global energy resources, suggests the author of a new book on the politics of China’s epic dam-building campaign.

The benefits of immigration outweigh the drawbacks, says a WUSTL economic historian. In the short run, immigrants may displace American workers, but history demonstrates that in the long-run, immigrants tend to spark technological innovation and strengthen the economy.
