You find a hair on a table top. A cigarette butt on the street. You take it home, and using not especially sophisticated tools, you recover traces of DNA. Can you now reconstruct the face of the person whose hair that was? Who smoked that cigarette?
Carl Sagan once wrote a mischievous paper called "A Search for Life on Earth from the Galileo Spacecraft". Being a living Earthling, he knew he'd find life here. So what was he really up to? The experiment he ran in 1990 is about to be repeated in a few weeks. Here's my closer look.
Every so often you see something deeply, truly, can't-believe-they-can-do-this astonishing. This is one of those. A small invention, inserted into a brain, that can silence a neural nightmare with the push of a button. Andrew Johnson is going to push that button.
Back in the 1950's, a young doctor decided to try hypnosis on a teenager suffering from the worst case of warts he'd ever seen. And it worked...even though it turned out the boy didn't have warts, but an incurable disease. Check out the before and after photos from the story in our Placebo show.

For over a decade (according to Know Your Meme), Dancing Spiderman has been shuffling and swaying online. Sometimes he dances in obscurity, sometimes people pay attention. I recently noticed him on the front page of reddit, which means a lot of people were watching him again, in the animated ...

Death, it appears, prefers gentlemen to ladies. Women don't just outlive men, they consistently outlive men at every stage of life. More boys die in utero, in infancy, in adolescence, in middle age, at every stage. That's why nature makes more of them. But why? What's so fragile about guys?
India has just banned dolphin entertainment parks. They are "morally unacceptable," says a government ministry. Meanwhile, on the other side of the planet, the U.S. Navy announced that 24 dolphins trained to sniff for underwater mines will be replaced by robots.
Our Animal Minds show questions whether dogs feel guilt...or whether we're just reading our own meanings into those puppy dog eyes. Dog owners, if you think you've got an incriminating photo of your canine looking remorseful, send it our way.
Moving north: two vans. Moving east: three taxis, a peddle cab and one lady walking. Moving west: six motorcycles, another taxi, a truck and a van. Moving south: a bicyclist, two cabs and a truck. All of them meet and there are no rules. Who lives? Who dies?
Take a bunch of broccoli, or make it a Slurpee, burger, pizza and fries, swallow, and ask yourself, "How much energy did I just consume?" Enough to light a flashlight? Run an electric toothbrush? If I were a lunch-eating light bulb, how long would I glow? Here's the answer.
