A new study confirms directly what scientists previously knew only indirectly: The poisonous “rotten egg” gas hydrogen sulfide, which plays a role in cardiovascular health, is generated by our body's growing cells.
On average, young newlyweds who are satisfied with their marriage gain weight in the early years after they exchange vows. That's the finding of a new study on marital satisfaction and weight gain, according to psychologist Andrea L. Meltzer, lead researcher and assistant professor in the SMU Department of Psychology.
Fruit flies fed an organic diet recorded better health outcomes than flies fed a nonorganic diet, according to a new study from Southern Methodist University, Dallas. Researchers in the lab of SMU biologist Johannes Bauer found that fruit flies raised on organic foods performed better on a variety of health tests. The flies on organic diets showed improvements on the most significant measures of health, namely fertility and longevity.
Light from two massive stars that exploded hundreds of millions of years ago recently reached Earth, and each event was identified as a supernova by SMU researchers. A supernova discovered Feb. 6 exploded about 450 million years ago, and a second supernova discovered Nov. 20 exploded about 230 million years ago.
In modern ecosystems, animals flourish amid lush vegetation. An SMU study examines whether that same relationship held true 150 million years ago when dinosaurs roamed the Earth. “The assumption has been that ancient ecosystems worked just like our modern ecosystems,” says SMU paleontologist Timothy S. Myers. “We wanted to see if this was, in fact, the case.”
A new species of coelacanth fish has been discovered in Texas. Pieces of tiny fossil skull found in Fort Worth have been identified as 100 million-year-old coelacanth bones. The new species is the youngest coelacanth to be discovered in Texas, and the only coelacanth discovered in the Dallas-Fort Worth area.
In the late 1800s, furious fossil speculation across the American West escalated into a high-profile national feud called the Bone Wars.
Powerful discovery tool is at work screening millions of drugs in the search to reverse chemotherapy drug-resistance in cancer.
With Type 2 human diabetes climbing at alarming rates in the United States, researchers are seeking treatments for the disease, which has been linked to obesity and poor diet. Now biologists at Southern Methodist University, Dallas, report they have developed a new discovery tool that will help researchers better understand this deadly disease.
