Chemical probe confirms that body makes its own rotten egg gas, H2S, to benefit health

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.

Fruit flies fed organic diets are healthier than flies fed nonorganic diets, study finds

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.

White dwarf supernovae are discovered in Virgo Cluster galaxy and in sky area “anonymous”

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.

Study finds Jurassic ecosystems were similar to modern: Animals flourish among lush plants

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.”

100 million-year-old coelacanth discovered in Texas is new fish species from Cretaceous

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.

Texas frontier scientists who uncovered state’s fossil history had role in epic Bone Wars
