A Bug-Like Robot Uses Electricity to Walk Upside Down
A bug’s life doesn’t seem half bad, if you can overlook the super-short lifespan or the threat of getting eaten by lizards or swatted at by humans. Flying is nice, as is being able to walk on ceilings. The versatility is enviable, which is why roboticists are on a quest to imbue machines with the…
How Trick-or-Treaters Can Stay Visible on a Dark and Spooooky Night
When I think of Halloween, I think of kids outside in the dark. Traditionally, this is the way it works. First, darkness makes everything just a little bit spookier and more Halloween-like. Second, the end of October used to be after the end of Daylight Savings Time such that it would get dark earlier. Of…
To Prevent Fires, One California Town Says 'Goat Fund Me'
Nestled in the foothills of California’s Sierra Nevada Mountains is the quaint Gold Rush town of Nevada City. Surrounded by unkempt brush, the old, highly flammable city is in danger: With California’s wildfires raging with unprecedented ferocity in recent years, one spark could doom Nevada City to the same fate that neighboring Paradise met in…
Robot Lawnmowers Are Killing Hedgehogs
While Americans still wrangle their overgrown lawns by pushing or riding a lawnmower, many Europeans have handed off that responsibility to robots. These beefy, Roomba-like mowers loop their way around a yard, keeping grass trim and neat. To many of their users, the bots are endearing. Their owners give them names or cover them in…
To Prevent Wildfires, Treat Utilities Like Railroad Barons
Actions have consequences, as our parents likely told us as kids. But inaction has consequences, too. Life or death consequences, in the case of California’s new normal of massive, climate-change-driven wildfires. After a series of devastating fires over the last few years, critics have turned their ire toward PG&E, a utility that brings electricity to…
A Genetic Mutation Might Explain Why Birth Control Can Fail
For nearly 60 years, hormonal contraceptives have freed women from their own biology, giving them autonomy over decisions about if, when, and how to start a family. But no form of hormonal birth control—pill, patch, ring, IUD—is 100 percent effective. Why that is, no one knows exactly. Now new research suggests that some of these…
Try Landing InSight on Mars (Without Exploding)
NASA just parked its InSight lander on Mars. Yes, Mars. This is a pretty big deal since quite a few Mars missions didn't make it. It's no wonder I get super excited about missions to Mars. For this particular mission, the lander, protected by a heat shield, used the Mars atmosphere to slow down. After…
These Wasp-Like Drones Lift Heavy Loads With Their Bellies
You might know wasps for their ability to brainwash cockroaches or inflict one of the most painful stings on Earth—one so powerful that the actual scientific advice to victims is to just lie down and scream until it passes. Lesser-known is the wasp’s superlative ability to carry loads that are unexpectedly heavy given the creature’s…
Prepare to Be Hypnotized By These Delicate Paper Robots
As far as plant names go, the sleepy plant—or shy plant, or shameplant, known more formally as Mimosa pudica—is hard to beat. Touch one of its leaves and it curls up like it’s embarrassed, the leaflets folding in on each other. It’s hypnotic and, well, kind of a surprising response for an organism without a…
Don't Fear the Robot Overlords—Embrace Them as Coworkers
In a chilly warehouse just outside of Boston, the brute toils away. It’s 600 pounds of orange and black metal and whirring motors, a massive robotic arm that picks up car parts and places them on a table. Like its ancestors have done for decades, this industrial robot does the heavy lifting that no human…
