What if everything around you had the potential to generate small amounts of energy?

We've seen flexible, even stick-on photovoltaic cells before, but these decal-style solars are compact and fun.

In a recent article in Scientific Reports, Stanford University mechanical engineering assistant professor Xiaolin Zheng and colleagues describe thin-film solar cells that can be peeled and stuck anywhere.

The researchers manufactured them on a reusable silicon and silicon dioxide wafer and then stuck them on paper, plastic, and window glass.

The original cell efficiency of 7.5 percent was maintained, and the manufacturing uses existing processes and materials. That … Read more

Next time you see a cockroach, don't scurry away faster than it can flee. In fact, if you're a lover of the weirder side of life, the intrusive insect could represent one heck of a science project.

For example, artist Brittany Ransom created Twitter Roach -- a discoid cockroach that can be controlled through tweets that it receives on the popular microblogging service. … Read more

People don't like to be disconnected from the Internet, even when they're cruising along at 30,000 feet in the air. Boeing knows this, so the airplane manufacturer ended up knee-deep in spuds to test its new developments in providing Wi-Fi access to flyers.

Tech developed in a Boeing lab looked like it could bolster Wi-Fi signals in the cabin of a plane. To test it out, Boeing engineers took over a decommissioned airplane and, naturally, filled the seats up with sacks of potatoes. Wait, what? Turns out there was a good reason for the grocery shopping spree.… Read more

You might agree that the complex design in a snowflake appears almost comparable to a work of art. Do you know how that tiny frozen masterpiece comes to life, though? If you're like me, you may never have witnessed a complete representation of that journey from cloud to ground before.

The trip isn't as simple as you think. … Read more

Last year, a scientist cracked the mystery of how Santa Claus manages his gift-delivery feats using futuristic technology. This year, dedicated scientists have finally revealed an explanation for how Rudolph, Santa's lead reindeer, got his red nose.

If you recall the legend, Rudolph was a bit of an outcast thanks to his bright and shiny red nose. All of the other reindeer might not laugh and call him names if they knew his nose was really the result of an issue with the microvascular flow in his nasal mucosa.

A collection of Dutch scientists contributed to a paper titled "Microcirculatory investigations of nasal mucosa in reindeer Rangifer tarandus (Mammalia, Artiodactyla, Cervidae): Rudolph's nose was overheated." … Read more

Jan Scheuermann can't use her limbs to feed herself, but she's pretty good at grabbing a chocolate bar with her robot arm.

She's become the first to demonstrate that people with a long history of quadriplegia can successfully manipulate a mind-controlled robot arm with seven axes of movement. Earlier experiments had shown that robot arms work with brain implants.

Scheuerman was struck by spinocerebellar degeneration in 1996. A study on the brain-computer interface (BCI) linking Scheuermann to her prosthetic was published online in this month's issue of medical journal The Lancet.

Training on the BCI allowed her to move an arm and manipulate objects for the first time in nine years, surprising researchers.

It took her less than a year to be able to seize a chocolate bar with the arm, after which she declared, "One small nibble for a woman, one giant bite for BCI." Check it out in the video below. … Read more

Isn't it about time the White House had a distraction from the fiscal cliff (whatever that is)? How about the feasibility of building a real-world Death Star?

As of today, a petition calling for the government of the United States to begin construction on a Death Star by 2016 has more than 25,000 signatures on the administration's official public suggestion page, surpassing the threshold that triggers a required response from the White House.

The petition hit the mark today, just a day before reaching its 30-day expiration date. Conveniently, petition creator "John D." of Longmont, Colo., even provided some politician-friendly talking points to promote the idea:… Read more

NASA is pretty confident the world is not going to end in the next 10 days, regardless of what the Mayan calendar or alleged rogue planet Nibiru might have to say about it.

Recently, NASA scientists gathered for a Google Hangout to debunk the multiple end-of-world theories alleged to transpire later this month. NASA even put together a YouTube video titled "Why the World Didn't End Yesterday" clearly meant to be released on December 22, after the winter solstice doomsday the day before. … Read more

PETALUMA, Calif.--Driving along the back roads of this idyllic, easy-going Northern California town, you'd never know that behind the walls of one of the most unassuming buildings around is perhaps the best collection of geek memorabilia in the world.

Welcome to Rancho Obi-Wan, Steve Sansweet's homage to his life's passion -- "Star Wars," a non-profit museum dedicated to serving "the public through the collection, conservation, exhibition and interpretation of [the films'] memorabilia and artifacts." Formerly Lucasfilm's head of fan relations and a Los Angeles-based reporter for the Wall Street Journal, Sansweet … Read more
