This Week in Science: T-Rexes and Hungry Sharks

This is pretty random . . . the Tyrannosaurus rex was around for 2.5 million years before it went extinct. So how many of them were there total? A new study put the number at around 1.7 billion T-rexes (check out the report HERE).  In related “Eating Machine News” . . . The people behind a new app called “SafeWaters”, claim their A.I. can predict your risk of a shark attack, with 89% accuracy (check out the screen shots). They’re hoping to have it on the App Store by July.
