The small town of Rjukan has long had to make do without sunlight during the cold Norwegian winters.
But that changed Wednesday, when the town debuted a system of high-tech mirrors to reflect sunlight from neighboring peaks into the valley below.
Rjukan, originally founded 100 years ago as an industrial outpost for the energy company Norsk Hydro, is nestled between several mountains and does not receive direct sunlight from late September to mid-March — nearly six months out of the year.

When Mike Napoli got up to bat in Game 6 of the World Series, my first thought was, "Oh my goodness, that beard is awful." But after the Red Sox's first baseman laid off a few bad pitches, I started liking the hair on his chin.
All that got me thinking about beards.
Sometime during evolution women lost their facial hair. This strong difference between the sexes implies that facial furriness, or the lack thereof, has played a role in how we picked our partners, at least at one point in human history.
Retired astronaut Chris Hadfield, author of the new book An Astronaut's Guide to Life on Earth, has flown three space missions, including 144 days on the International Space Station. Hadfield talks about life in zero gravity, his one fear while in orbit, and how he went from test pilot to astronaut.
This is SCIENCE FRIDAY. I'm Ira Flatow. When you think about Albert Einstein, the words E=MC squared and Theory of Relativity naturally come to mind. But Einstein did not win his Nobel Prize for that work. Instead, he won the prize for figuring out how light interacts with objects and for believing, when almost no one else did, that light and energy are carried as discreet packets called quanta.
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.
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.
"There is real danger of a disconnect between what's on your business card and who you are deep inside, and it's not a disconnect that the world is ready to be patient with." — Alain de Botton
Success has become synonymous with financial wealth, influence and status. But can we define success in another way — one that welcomes a broader range of accomplishment? It may not be as obvious as you think. In this hour, TED speakers share ideas for what makes us successful.
Leaving a high-flying job in consulting, Angela Duckworth took a job teaching math to seventh-graders in a New York public school. She quickly realized that IQ wasn't the only thing separating the successful students from those who struggled. Here, she explains her theory of "grit" as a predictor of success.

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."
In a barn outside Manhattan, Kan., researchers from Kansas State University are trying to solve the riddle of bovine respiratory disease. They're sticking plastic rods down the noses of 6-month old calves, collecting samples of bacteria.
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. In an odd twist, this old-fashioned crop even seems to be catching on among consumers who are looking for "ancient grains" that have been relatively untouched by modern agriculture.
Sorghum isn't nearly as famous as the big three of global agriculture: corn, rice and wheat. But maybe it should be. It's a plant for tough times, and tough places.
