To Learn How Your Camera Works, Try Building One

Digital cameras are ubiquitous today — even $20 cell phones have them built in. But few people actually know how a digital camera works. Shree Nayar, a computer scientist at Columbia University, set out to change that with his Bigshot Do-It-Yourself Digital Camera kit, which gives tinkerers a view of a camera's anatomy.

Hurricane Sandy Recovery, One Year Later

A year after Hurricane Sandy, recovery efforts are still ongoing, and questions remain about how to rebuild and prepare the coastlines for the next storm. A group of experts discusses rebuilding and protective options — from sea walls to "oyster-tecture" — and considers calls for a "managed retreat" from the shore.

A few years ago, cognitive scientist Duje Tadin and his colleague Randolph Blake decided to test blindfolds for an experiment they were cooking up.

They wanted an industrial-strength blindfold to make sure volunteers for their work wouldn't be able to see a thing. "We basically got the best blindfold you can get." Tadin tells Shots. "It's made of black plastic, and it should block all light."

Dogs can pick up emotional cues from another dog by watching the direction of its wagging tail, a new study suggests.

Much of the world is turning hotter and dryer these days, and it's opening new doors for a water-saving cereal that's been called "the camel of crops": sorghum.

International monitors announced Thursday that Syria has completely destroyed its equipment for making and filling chemical weapons. But the destruction of the chemicals themselves — more than 1,000 tons of toxic ingredients — is going to be a far more daunting task.

Why Are Kids Who Get Less Candy Happier On Halloween?

Kids might be more satisfied if they get one good treat instead of one good treat and one lesser treat.

What makes trick-or-treaters happy is candy. And more candy is better, right?
