In a serendipitous moment, scientists studying light sensing molecules in plants have discovered that they are also temperature sensors.The discovery may eventually allow them to design crop varieties that are better able to cope with a warming world.
As floodwaters surge along major rivers in the midwestern United States, a new study from Washington University in St. Louis suggests federal agencies are underestimating historic 100-year flood levels on these rivers by as much as five feet, a miscalculation that has serious implications for future flood risks, flood insurance, and business development in an expanding floodplain.
The slow rebound of the bedrock as ice melts can be used to weigh the Antarctic ice sheet. Calibrating rebound will make it possible to measure how much mass the has lost since the ice sheets reached their maximum extent more than 20,000 years ago and how much it is currently losing. Two National Science Foundation grants will fund the installation of seismographs to calibrate crucial parts of the Antarctic ice-weighing machine.
Christopher Field, PhD, one of the leaders of the United Nation’s Intergovernmental Panel on Climate Change will be on the campus of Washington University in St. Louis as an I-CARES Distinguished Speaker at 5 p.m. Tuesday, Sept. 21, in Graham Chapel. Field and a team of scientists have calculated how fast temperature zones are likely to move across the planet in the future and whether plants and animals will be able to migrate fast enough to stay ahead of the heat.
America has the potential to solve its energy crisis over the next decade, but doing so will require immediate investment in clean energy technologies, says Mark S. Wrighton, chancellor of Washington University in St. Louis and vice chair of a National Resource Council report on America’s energy challenges. The report will be the topic of a symposium to be held from 12:30 to 5:30 p.m. Monday, Nov. 2, in the May Auditorium in Simon Hall on the Danforth Campus of Washington University in St. Louis.
Distinguished environmental law and policy scholars and scientists from around the country will gather at WUSTL Oct. 30 to discuss “International Climate Change: Post-Kyoto Challenges.”
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.
LowryThe President’s call to end a decades-old ban on offshore oil and gas drilling highlighted key differences in the big-oil platforms of presumptive Republican and Democratic presidential nominees Obama and McCain, suggests William Lowry, a WUSTL expert on the politics of environmental and energy issues.
President Bush’s call this week for Congress to end its decades-old ban on offshore oil and gas drilling has highlighted key differences in the big-oil platforms of presumptive Republican and Democratic presidential nominees Barak Obama and John McCain, suggests William Lowry, an expert on the politics of environmental and energy issues at Washington University in St. Louis.
A team of seismologists from Washington University in St. Louis, like members of the starship Enterprise, will “boldly go where no man has gone before” after Thanksgiving this year. The team, led by Douglas A. Wiens, Ph.D., Washington University professor of earth and planetary sciences in Arts & Sciences, will go to remote regions of Antarctica to place seismographs in both east and west Antarctica to learn about the earth beneath the ice, and glean information about glaciers, mountains and ice streams.
