The lectures explore every aspect of the Earth and are designed to appeal to the curious lay public.Videos have been the bailiwick of rock stars at least since the days of Bob Dylan. But now they’re spilling over into a new arena — academia. Michael E. Wysession, Ph.D., associate professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has 48 lectures on planet Earth coming out in a video format in February. It’s a sort of brainiac’s boxed set. Each 30-minute lecture focuses on an aspect of the Earth, from its origins and composition to its climate, orbit, pollution and relationship to human history.

Innovative researcher George Whitesides will speak on revolutionary ideas in chemistry that may lead to a new understanding of the origin of life for the Ferguson Science Lecture at 11 a.m. on Wed., Feb. 6 in Graham Chapel as part of the Assembly Series.

Innovative researcher and distinguished professor George M. Whitesides, Ph.D., will speak on revolutionary ideas in the field of chemistry about the origin of life at 11 a.m. Wednesday, Feb. 6, in Graham Chapel as part of the Assembly Series. His talk, “Questions about Questions about the Origin of Life,” is the annual Ferguson Science Lecture […]

Lars Angenent in his lab.A team of researchers headed by Lars Angenent, Ph.D., assistant professor of energy, environmental and chemical engineering at Washington University in St. Louis, is plying new techniques to produce a biofuel superior to ethanol.

The university hopes car-sharing will make it easier for faculty, staff and students to use public transportation or carpools to commute to and from campus.Washington University in St. Louis’ Parking & Transportation Services and Enterprise Rent-A-Car© have partnered to bring WeCar™, a car-sharing program, to the university’s Danforth Campus. The program, the first of its kind in the St. Louis area, allows Washington University students, faculty, staff and employees of qualified service providers over age 18 to rent vehicles at an hourly rate. The vehicles will be available 24 hours a day, seven days a week.

Pratim Biswas, Ph.D., chair of WUSTL’s energy, environmental and chemical engineering department, heads a project involving Washington University, Chrysler LLC and Ameren Corporation to test a mercury removal process in a full-scale power plant.Washington University in St. Louis is partnering with Chrysler LLC and a major Midwest utility company in a project to determine if paint solid residues from automobile manufacturing can reduce emissions of mercury from electric power plants. The project is based upon the technical expertise of Pratim Biswas, Ph.D., Stifel & Quinette Jens Professor of Environmental Engineering Science who has demonstrated the effectiveness of titanium dioxide in controlling mercury in lab and recent field studies. He heads the project that will test a mercury removal process in a full-scale power plant.

Rather than being gentle giants, new research reveals that Pleistocene cave bears ate both plants and animals and competed for food with the other contemporary large carnivores of the time.Rather than being gentle giants, new research conducted in part by Erik Trinkaus, Ph.D., professor of anthropology in Arts & Sciences, reveals that Pleistocene cave bears ate both plants and animals and competed for food with the other contemporary large carnivores of the time: hyaenas, lions, wolves and our own human ancestors.

When complete, China’s Three Gorges Dam on the Yangtze River will cost $25 billion and displace more than 1.4 million people.The Chinese government’s recent decision to scrap controversial plans for a huge dam at Tiger Leaping Gorge on the upper reaches of the Yangtze River represents a milestone for growing grassroots political movements in China, suggests the author of a new book on the politics behind China’s epic dam-building campaign.

Helium is drifting away.In America, helium is running out of gas. The element that lifts things like balloons, spirits and voice ranges is being depleted so rapidly in the world’s largest reserve, outside of Amarillo, Texas, that supplies are expected to be depleted there within the next eight years. This deflates more than the Goodyear blimp and party favors. Its larger impact is on science and technology, according to Lee Sobotka, Ph.D., professor of chemistry and physics in Arts & Sciences at Washington University in St. Louis.

It’s easy being green: Idling computers and bottled water, when used wisely, can make minimal impacts on the Earth.Want to begin to be more environmentally friendly in 2008 but can’t afford a hybrid car? Don’t worry — there are plenty of ways to lessen your impact on the environment that don’t come with such a daunting price tag, says Matt Malten, assistant vice chancellor for campus sustainability at Washington University in St. Louis. And they likely will even save you some money without cramping your carbon-creating lifestyle — much.
