The Tyrannosaurus rex's tiny arms were more useful than previously thought, according to findings presented at the Society of Vertebrate Paleontology's annual meeting. Researchers used turkey and alligator elbows to simulate movements of a T. rex joint, finding that its ability to rotate its forearms and hands toward the chest may have made it easier to bring prey closer to its mouth.

A chemical reaction between formaldehyde and sulfur dioxide may be behind much of China's notorious winter smog, a study published in Geophysical Research Letters suggests. Researchers say more progress could be made in curbing the smog by focusing efforts on slashing formaldehyde emissions as well as sulfur dioxide emissions.

Youths with consistent participation in organized sports from ages 5 to 17 had improved bone density at age 20, compared with those who dropped out from the sport and those who never played, Australian researchers reported in the Journal of Bone and Mineral Research. The findings also showed that men who played consistently since childhood had greater whole-body density and those who only played in adolescence had better leg bone density, but only leg bone density was improved among women with consistent sports participation since childhood.

Skin flap wounds exposed to fumes from electronic cigarettes increased the risk of flap necrosis to the same degree as exposure to conventional cigarette smoke, researchers reported in JAMA Facial Plastic Surgery.
Shaun Desai, assistant professor of head and neck surgery, wrote in an editorial accompanying the study
that patients should be asked about e-cigarette use and counseled to quit at least four weeks before any surgical procedure.
