Ever wonder why humans cry? A professor of behavioral neurology answers some questions, and helps give us a better understanding of how a feeling in our guts can come out as water in our eyes.
Data from DIY cicada trackers and soil temperature readings from the U.S. Climate Reference Network are helping us predict this spring's Brood II cicada emergence. Check out the map (which already has some cicada sightings!), and let us know if you're seeing and hearing cicadas near you.
SpaceX calls it the "Grasshopper" — it's a rocket that doesn't fall back to Earth haphazardly after launch. It carefully returns itself to the launchpad standing up, right where it started.
