A hard hit to the head typically prompts physicians to look for signs of a concussion based on symptoms such as forgetfulness, wobbly gait and disorientation. But symptoms such as those are subjective, says physiologist Sushmita Purkayastha, Southern Methodist University, Dallas. Now a new study aims to find noninvasive objective indicators to diagnose whether an athlete has suffered a concussion.
Each semester, SMU biology professors Pia Vogel and John Wise welcome a handful of dedicated and curious students to their lab in the SMU Dedman Life Sciences building. The SMU undergraduate students and Dallas-area high school students get hands-on experience working on cancer research in the combined SMU Department of Biological Sciences laboratories of Wise and Vogel.
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, say astrophysicists at SMU. The massive explosion, Supernova 2013j, was one of the closest to Earth in recent years. Analysis of the exploding star's light curve and color spectrum found its sudden blast hurled material from it at 10,000 kilometers a second.
Identification of a new species of marine mammal has intensified the rare animal’s brief mysterious journey through prehistoric time. A big, hippo-sized animal with a long snout and tusks — the new species is a marine mammal belonging to the order Desmostylia. But unlike other marine mammals alive today — such as whales, seals and sea cows — desmostylians went totally extinct.
SMU's Dara Rossi was interviewed by the summer reading program Shelly's Summer Bookworms for Dallas TV station WFAA. Rossi is a clinical assistant professor and director of SMU's Teach for American Teacher Education Program in the Simmons School of Education and Human Development. She was asked how using technology can help young students learn to read. Rossi is an experienced educator with a strong science background, including K-12 curriculum development and administration.
Drugs important in the battle against cancer responded the way they do in real life and behaved according to predictions when tested in a computer-generated model of one of the cell’s key molecular pumps — the protein P-glycoprotein, or P-gp. Biologists at SMU developed the computer generated model to overcome the problem of relying on only static images for P-gp's structure, said biologist John G. Wise, lead researcher.
Researchers at Southern Methodist University, Dallas, have discovered three new drug-like compounds that could ultimately offer better odds of survival to prostate cancer patients. The drug-like compounds can be modified and developed into medicines that target a protein in the human body that is responsible for chemotherapy resistance in cancers, said biochemist Pia D. Vogel.
Initial data from a new U.S.–based physics experiment indicates scientists are a step closer to understanding neutrinos, the second most abundant particle in the universe, says SMU physics professor Thomas Coan, a principal investigator on the project. Neutrinos are little understood, but indications are they hold clues to why matter overwhelmingly survived after the Big Bang instead of just energy in the form of light.
