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.”

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.

The annual meeting of the Biomedical Engineering Society began Oct. 1 and continues through Saturday, Oct. 4, at the Renaissance Grand Hotel 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.

The Donald Danforth Plant Science Center will commemorate its 10th anniversary at a community-wide event celebrating science in St. Louis and the center’s international culture at 1 p.m. Sunday, Sept. 28.

Unicellular nitrogen-fixing cyanobacteriaA 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.

The International Center for Advanced Renewable Energy and Sustainability (I-CARES) will host Nathan Lewis, Ph.D., as an I-CARES Distinguished Speaker at 4 p.m. Tuesday, Sept. 23. Lewis will present a lecture titled “Where in the World Will Our Energy Come From?”

Researchers at Washington University in St. Louis are proposing to borrow a process used in breweries and wastewater treatment facilities to make corn ethanol more energy efficient. They are exploring the use of oxygen-less vats of microorganisms that naturally feed on organic waste produced from the ethanol fermentation process.
