Explore the physics behind space elevators, which would theoretically use a cable anchored to Earth and extending into space. Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more exciting: elevators. […]

TED-Ed explains the science of how viruses can jump from one species to another and the deadly epidemics that can result from these pathogens. Here’s a story that happened right here in Maryland. At a Maryland country fair in 2017, farmers reported feverish hogs with inflamed eyes and running snouts. While farmers worried about the […]
