Human Experiments: The Good, the Bad, and the Ugly

Research involving human subjects is littered with a history of scandal that often shapes people’s views of the ethics of research. Often the earliest cited case is English physician Edward Jenner’s development of the smallpox vaccine in 1796, where he injected an eight-year-old child with the pus taken from a cowpox… » 6/17/15 6:39am 6/17/15 6:39am

Female Orgasm Explained With Fifth Grade Science Experiments

Talking about sex doesn’t have to be X-rated – and in some cases, it shouldn’t be. That’s why I love this video from Wired’s Data Attack team, which illustrates facts and statistics about women’s orgasms using classic elementary school experiments. You’ll never look at the egg-in-a-bottle experiment the same way again.

High-Speed Footage of Levitating Water Drops Looks Like a Fireworks Show

You’ve probably seen those experiments where scientists are able to levitate foam balls, or tiny drops of water, using nothing but ultrasonic sound waves. It’s utterly mesmerizing to watch something just float in mid-air, but magnitudes cooler when filmed with a camera recording at 20,000 frames per second. » 4/30/15 11:30am 4/30/15 11:30am

Super-Cooled Nickel Ball Is Even Better Than Red Hot Nickel Ball

The red-hot nickel ball is our all-time favorite destroyer of basically anything on the planet, transforming everything from Velveeta to Peeps into sticky, bubbling cauldrons of processed-chemical goo. Now the ball is rolling in the other direction with a liquid nitrogen-cooled nickel ball that's up to all sorts of… » 11/13/14 2:08pm 11/13/14 2:08pm

Man loses 37 pounds by eating exclusively at McDonald's for 90 days

A man lost 37 pounds and his cholesterol level dropped from 249 to 170 by eating exclusively at McDonald's for 90 days. He ate everything: from Big Macs to salads to sundaes to shakes to quarter pounders. It's the antithesis of Supersize Me, the pseudo-documentary of a man who did the same—with two crucial differences: » 1/08/14 7:50am 1/08/14 7:50am

Watch Super-Heated Water Droplets Navigate a Maze All On Their Own

When a drop of water hits a hot enough pan, it doesn't instantly boil away. Instead, the drop's outer layer vaporizes, producing an insulating effect that causes it to skitter across the hot surface. This is known as the Leidenfrost effect, and it can be harnessed for some neat tricks, like the Mythbusters being able… » 9/30/13 9:35am 9/30/13 9:35am

Apple Juice: How to Charge Your Phone With Pocket Change and Fruit

Arthur C. Clarke wrote that "any sufficiently advanced technology is indistinguishable from magic," but he was wrong. It's easy to tell the difference—technology works. For example, "remote-viewing" mentalists claim they can see events far away, yet they fail every test. In fact, remote viewing is simple: It's called… » 5/31/13 2:00pm 5/31/13 2:00pm
