Movies like The Day After Tomorrow feed into that fear, with visions of unimaginable storms and populations fleeing rapidly changing temperatures. While Hollywood clearly takes liberties with the speed and magnitude of disasters, several recent studies have raised … Read more
Space flight doesn’t usually come to mind when you think of the quiet, green mountains of North Carolina. It is true that, in the early 1960s, NASA built the (now defunct) Rosman Satellite Tracking and Data Acquisition facility among the rolling hills of Appalachia to track Soviet satellites and relay communications for the Gemini and … Read more
A new paper that takes a look at the Fermi Paradox using the Drake Equations has suggested an uncomfortable solution: maybe we’re alone in the galaxy. If you haven’t heard of the Fermi Paradox, it goes something like this: given the infinity of the universe and the implied probability of life evolving elsewhere, how is … Read more
After its “birth” in the Big Bang, the universe consisted mostly of hydrogen and a few helium atoms. These are the lightest elements on the periodic table. More or less all elements heavier than helium were produced in the 13.8 billion years between the Big Bang and the present day. Stars have produced many of … Read more

Scientists have developed a quadrupedal robot that can use its two front legs to grasp and handle objects while walking on its hind legs. Quadruped robots usually take the form of robot dogs, including Boston Dynamics’ Spot. They can traverse challenging terrain at speed and usually have low centers of gravity. Most object-manipulating quadrupeds have … Read more
