Distinguished environmental law and policy scholars and scientists from around the country will gather at Washington University in St. Louis to discuss “International Climate Change: Post-Kyoto Challenges,” from 8:30 a.m. to 4 p.m. on Oct. 30 in Anheuser-Busch and Seigle Halls. “The international community is aiming to complete negotiations by the end of 2009 on a new climate change agreement to take effect when the Kyoto Protocol expires in 2012,” says Maxine Lipeles, J.D., director of the Interdisciplinary Environmental Clinic and senior lecturer in law. “This conference will address the critical question of what roles the world’s two largest emitters – the U.S. and China – will play under the new agreement.” The conference, hosted by Washington University School of Law’s Whitney R. Harris World Law Institute, is free and open to the public, but registration is required.

Wind power is one practical alternative to petroleum.The director of a sustainable energy research center at Washington University in St. Louis is challenging the next president of the United States to set goals in energy research and implementation. “I would like to see the next president of the United States set a similar goal to President Kennedy’s from 1961 — to put a man on the moon and to bring him back to Earth by the end of the decade,” says Himadri B. Pakrasi, Ph.D., the George William and Irene Koechig Freiberg Professor of Biology in Arts & Sciences, and Professor of Energy in the School of Engineering and Applied Science.

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.

A team of researchers headed by biologists at Washington University in St. Louis has sequenced the genome of a unique bacterium that manages two disparate operations — photosynthesis and nitrogen fixation — in one little cell during two distinct cycles daily.
