Bitten Bones Show Alligators are Rough Feeders

NationalGeographic

National Geographic featured the research of Stephanie Drumheller, an earth and planetary sciences lecturer. Drumheller’s work involved giving alligators n pig bones or cow legs. Through understanding the damage modern alligators leave on bones, Drumheller and other paleontologists can follow the depredations of alligators and their crocodile cousins through time. “In order to see the

Triassic Bites and a Carnivore Conundrum

NationalGeographic

National Geographic featured an in-depth story on the research of Stephanie Drumheller, an earth and planetary sciences lecturer. She and her Virginia Tech colleagues examined 220-million-year-old bite marks in the thigh bones of an old reptile and found evidence that two predators at the top of their respective food chains interacted—with the smaller potentially having

Tooth Serves as Evidence of 220 Million-Year-old Attack

Reconstruction of the interaction of large land predators (rauisuchid) and aquatic predator (phytosaur) about 210 million years ago based on research by a joint team of University of Tennessee and Virginia Tech researchers. Christopher Hayes, a freshman at Virginia Tech, composed the drawing.

At the beginning of the age of dinosaurs, gigantic reptiles—distant relatives of modern crocodiles—ruled the earth. Some lived on land and others in water and it was thought they didn’t much interact. But a tooth found by a UT researcher in the thigh of one of these ancient animals is challenging this belief.

Threatening Asteroid a Gravity-defying Ball of Rubble

WBIR-TV

WBIR-TV featured the research of Ben Rozitis, a postdoctoral researcher, which found that a gravity-defying asteroid that poses one of the largest threats to Earth is actually more like a giant clump of flour. The fact that the rocks and dust are not flying apart means the asteroid is being held together by something more

When faculty members Karen Lloyd and Andrew Steen saw an opportunity to introduce a group of inner-city New Jersey high school students to science, they made it happen. Lloyd, an assistant professor of microbiology, and her husband, Steen, an assistant professor of earth and planetary sciences, just completed their second summer program with students and teachers from Malcolm X Shabazz High School in Newark.

Two Doctoral Students Win NASA Fellowships to Further Their Studies

Two earth and planetary sciences doctoral students will be furthering their study of the cosmos with help from NASA. NASA Earth and Space Sciences Fellowships are awarded once a year “to ensure continued training of a highly qualified workforce in disciplines required to achieve NASA’s scientific goals.” The recipients, including UT’s Eric MacLennan, of Boston, Massachusetts, and Richard Cartwright, of Atlanta, Georgia, will each get $30,000 a year for three years.

News Sentinel: UT expert, Scientists excited to learn from approaching comet ISON

The Knoxville News Sentinel spoke with Sean Lindsay, a postdoctoral research associate in the Department of Earth and Planetary Sciences, about Comet ISON. Some astronomers have hyped Comet ISON as the “comet of the century,” but whether the hurtling ball of ice and dirt will earn its title depends largely on surviving today’s trip around
