The Roar: Humans can’t bolt much faster than Usain — What science says about the 100m world record

Sports writer Matt Porter referenced the research of SMU biomechanics expert Peter Weyand for an article in the news blog The Roar examining the potential for humans to continue improving strength and speed beyond what has already been achieved. Porter quotes Weyand for his expertise on the mechanics of running and speed of world-class sprinters like Usain Bolt. The article "Humans can't bolt much faster than Usain: What science says about the 100m world record" published Aug. 15, 2016.

Textbook theory of how humans populated America is “biologically unviable,” study finds

The established theory of how Ice Age peoples first reached the present-day United States is now challenged by an unprecedented study that concludes that entry route was “biologically unviable.” The North American ice-free corridor, thought to have been used by the first colonizers, only became biologically viable 12,600 years ago — after they would have arrived. Researchers suggest a Pacific coast was the entry route.

Weyand is featured in the August 2016 issue of the science news magazine Scientific American. Science writer and associate editor Dina Fine Maron reports on Weyand's leading-edge research about the key to human speed for sprinters in the article "The Secret to Human Speed" and the video report "How Elite Sprinters Run So Fast."

KERA: Thanks To CT Scans, Scientists Know A Lot About Texas’ Pawpawsaurus Dinosaur

"There's no relationship between dinosaurs and armadillos, which are mammals, but it is interesting that something that looked like an armadillo was here in Texas 100 million years before highways." — Jacobs

Wildfire on warming planet requires adaptive capacity at local, national, int’l scales

Industrialized nations that view wildfire as the enemy have much to learn from people in some parts of the world who have learned to live compatibly with wildfire, says a team of fire research scientists.

Dallas Morning News: North Texas dino had tough armor, keen sense of smell

Pawpawsaurus had large nostrils that looked "like a trumpet bell" and wide air passages that helped the 100-million-year-old North Texas dinosaur smell predators, look for food or find mates.

Live Science: Fearsome Dinosaur-Age ‘Hammerhead’ Reptile Ate … Plants?

Hammerhead reptile, vegetarian, Jacobs, SMU Science journalist Laura Geggel tapped the expertise of SMU Earth Sciences Professor Louis L. Jacobs for a recent article about a prehistoric plant-eating reptile. A professor in Dedman College's Roy M. Huffington Department of Earth Sciences, Jacobs is a world-renowned vertebrate paleontologist. He joined SMU's faculty in 1983 and in 2012 was honored by the 7,200-member Science Teachers Association of Texas with their prestigious Skoog Cup for his significant contributions to advance quality science education.

Good news! You’re likely burning more calories than you thought

Counting calories burned is popular, but leading standardized equations used to predict or estimate calories burned while walking assume that one size fits all. They’ve been in place for close to half a century and were based on data from a limited number of people. A new SMU study found that under firm, level ground conditions, the leading standards are relatively inaccurate and have significant bias — predicting too few calories burned in 97 percent of cases researchers examined.
