Researchers have used new lunar satellite images to pinpoint exactly where the Apollo 17 astronauts took their iconic photographs of the moon’s surface. That data has in turn allowed planetary scientists to build the most precise 3-D maps yet of the Apollo 17 mission site. “We’re making these images more valuable by giving them incredibly accurate coordinates,” said planetary scientist Mark Robinson of Arizona State University. “The 3-D models of areas explored by astronauts may enable future exploration of these sites and allow us to better understand the observations they made at the time.” Robinson and his team’s study of the Apollo 17 site was published online April 1 in the Journal of Geophysical Research. Cameras on NASA’s Lunar Reconnaissance Orbiter (LRO) have photographed the ... Continue reading →

The sons of Red Bull are sporting record concentrations of caffeine.Are energy drinks capable of pushing some people into caffeine-induced psychotic states? Some medical researchers think so, under the right set of conditions. Red Bull, for all its iconic ferocity, is pretty tame, weighing in at approximately half a cup of coffee. Drinks like Monster Energy and Full Throttle push it up to 100-150, or the equivalent of a full cuppa joe, according to USDA figures at Talk About Coffee. That doesn’t sound so bad—unless you’re ten years old. A little caffeine might put you on task, but an overdose can leave you scattered and anxious—or worse. If you cut your teeth on Coke and Pepsi, then two or three energy drinks can delivery an ... Continue reading →
