Tyrannosaurus rex relied on its elite nose to sniff out victims and take down live prey at night, a new study shows.
Some scientists previously had considered T. rex a scavenger of carrion, rather than a hunter, due to various features including its sense of smell. The new study, which analyzed data for a range of meat-eating dinosaurs as well as living carnivores (alligators), suggests T. rex likely was a true hunter and took down live prey such as other dinosaurs.

Tyrannosaurus Rex and Velociraptor both had a very keen sense of smell according to a study published today. These frightening predators are believed to have used this keen sense of smell to hunt out prey, navigate and carry out activities in low-light conditions.

//////////////////Statin Use Associated with Drops in PSA Levels
Prostate-specific antigen levels appear to drop after men begin using statins, according to an observational study published online by the Journal of the National Cancer Institute.
The study included some 1200 men with healthy prostates who had their PSA levels measured within 2 years before filling prescriptions for a statin and again within 1 year afterward. Overall, the median PSA concentration fell by roughly 4% after statin initiation.
Despite the drop, editorialists point out that these findings do not clarify whether statins may be "preventive, therapeutic, or simply affect PSA level itself." They conclude that "only a randomized trial with histological endpoints can determine whether statins affect a man's risk of prostate cancer."
