Who can ignore this 500-pound gorilla?It’s a 500-pound gorilla that Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, sees standing on the speaker’s dais at political rallies, debates and campaigns. Its name is population growth. “Population growth is driving all of our resource problems, including water and energy. The three are intertwined,” Criss says. “The United States has over 305 million people of the 6.7 billion on the planet. We are dividing a finite resource pie among a growing number of people on Earth. We cannot expect to sustain exponential population growth matched by increased per capita use of water and energy. It’s troubling. But politicians and religious leaders totally ignore the topic.”

SciFest 08, a new annual event at the St. Louis Science Center, brings together world-renowned scientists and experts – including those from Washington University – to help participants see science in a new way. There are hundreds of science experiences, including presentations and hands-on exhibits.

When the red, red robin comes bob, bob bobbin’ along, think West Nile Virus (WNV).This one’s for the birds. A study by biologists at Washington University in St. Louis shows that the more diverse a bird population is in an area, the less chance humans have of exposure to West Nile Virus (WNV). Now, let’s hear it for the birds. “The bottom line is that where there are more bird species in your backyard, you have much lower risk of contracting West Nile fever,” said Brian Allan, doctoral candidate in biology in Arts & Sciences at Washington University in St. Louis.

Whether watching the All-Star Game, a World Series game or just a regular-season Tuesday afternoon game, it’s nearly guaranteed that fans will see daring slides, both feet-first and head-first, and even slides on bang-bang plays at first. Who gets there faster, the head-first slider or the feet-first? The head-first player, says David A. Peters, Ph.D., the McDonnell Douglas Professor of Engineering at Washington University in St. Louis, and big-time baseball fan. He says it’s a matter of the player’s center of gravity.
