We know that dust can make us sneeze, but can the scourge of clean homes everywhere also make us gain weight? Possibly, according to a recent study in Environmental Science and Technology. In a manner of speaking, anyway.

Erectile dysfunction can be hard. No, this is not a joke, even though that pun was absolutely intended. The simple fact is that ED can have psychologically devastating effects that we shouldn't make light of. If folks are too ashamed to talk about these issues, they're more likely to turn to things like male enhancement coffee.

“We are living in a plastic age,” Captain Charles Moore tells PopSci. “We're ignorant of its dangers, and we haven't learned properly to fear or to respect it.”

We see hundreds or even thousands of images a day, and almost all of them have been digitally manipulated in some way. Some have gotten basic color corrections or simple Instagram filter effects, while others have received full on Photoshop jobs to completely transform the subject. It turns out humans aren't very good at recognizing when an image has been manipulated, even if the change is fairly substantial. Hany Farid is a professor of computer science at Dartmouth College who specializes in photo forensics, and while he can't share all of his fancy software tools for detecting editing trickery, he has shared a few tips for authenticating images on your own.

Turns out bacteria cells might not actually outnumber your own, but there's still a heck of a lot of the little buggers living all over you. And since you're already sharing the rest of yourself with your partner—your bed, your shower, your saliva—it makes sense that you'd share bacterial colonies too.

Lots of people rely on insulin injections to manage their blood sugar. But after nearly a century of helping diabetics, the hormone is starting to look appealing for other uses as well.

NASA is forever linked to space, a plucky government agency bravely hurtling people and robots into the great beyond. Yet the agency has always had as much of an earth-bound mission as an outer space one. The “Aeronautics” at NASA may get short shrift, but with 300 videos of archival aviation tests released online this week, there's plenty of airborne excitement waiting for viewers.

If humans are ever really going to make it to Mars, we're going to need a bigger boat. Today's spaceships are built for short hauls to and from the International Space Station, a mere six or so hours away. These ships, like the Russian Soyuz, SpaceX's Dragon, NASA's upcoming Orion capsule, are small, cramped, and they don't have bathrooms or sleeping quarters.

It's relatively new to America's drug scene, but in the last few years, its victims have included everyone from musician Prince to a 10-year-old boy in Miami. The culprit is fentanyl, a lesser-known—but incredibly lethal—opioid that has become increasingly prevalent in the United States.

In an effort so astronomically full of cooperation and enthusiasm it could have been scripted, last Sunday, some of the streets near Comodoro Rivadavia, Argentina went dark.

Robots often imitate life. We are used to bots mimicking humans, and animals, but there is plenty of life beyond the constraints of legged bodies that can inspire useful machines. Researchers at the University of California, Santa Barbara and Stanford University have made a machine with long tendrils that can perform dangerous tasks like reaching through rubble to pump air to a trapped earthquake survivor.

After that oyster slides into your mouth, and you've tossed another empty shell onto your plate, do you ever think about where those shells end up?

No matter how many times I tell my local Thai restaurant that I don't want plastic forks with my take-out, I open the bag to find handfuls of unnecessary eating utensils in there, every time. Roland Geyer, an industrial ecologist at the University of California at Santa Barbara, has similar problems. “Sometimes at the supermarket I have to fight to not get plastic bags,” he says.

Dogs are too pure for this world. This fact is known. If supernatural explanations were sufficient, we could safely say that dogs descended from the heavens to bring us joy.

News articles over the past few years have implicated everything from sunlight's ultraviolet radiation to burnt toast as potential carcinogens, or cancer-causing substances. So, should you be rushing to cut these everyday exposures out of your life? Well, it depends on the material you are talking about, and how much and how often you are in contact with it.
