Tigers aren’t known for being accommodating, but a new study in the Proceedings of the National Academy of Sciences indicates that the carnivores in Nepal are taking the night shift to better coexist with humans. The revelation that tigers and people are sharing exactly the same space – the same roads and trails – of…
Does E always equal mc²? University of Arizona physicist Andrei Lebed suspects not – and plans to try and check. Einstein’s famous equation describes the fact that energy and mass are essentially the same thing and can be converted into one other. It’s since been validated in countless experiments and calculations – indeed, many technologies…
The Obama administration is issuing the first-ever national standards to control air pollution from gas wells that are drilled using a method called hydraulic fracturing, or fracking, but not without making concessions to the oil and gas industry. Much of the air pollution from fracked gas wells is vented when the well transitions from drilling…
One day after new test results showed that only 32 percent of U.S. 8th graders are proficient in science, a group of 26 states has helped draft a document that may bring about a major overhaul of science education in this country. Known as the Next Generation Science Standards, the draft sets ambitious new expectations…
Kids love smartphones and tablets, and that makes the devices great tools for learning math and science. Apps for mobile devices can help make even the most abstract concepts—like algebra or physics—engaging. And smartphones and tablets can be carried out into nature to help students understand what they’re seeing. Star Walk, for example, identifies more…
Thirty-three light-years away, in the constellation Leo the lion, astronomers say they have found a world considerably smaller than Earth, orbiting a dim red-dwarf star. That’s something to think about. While scientists have confirmed the existence of more than 700 so-called exoplanets since 1995, most of them have been giant — many considerably larger than…
