What you need to know about TV power consumption

Since 2011 the FTC has required that every TV display a yellow and black Energy Guide label estimating how much it costs to run for a year. The label assumes a price for electricity (11 cents/kWh) and a baseline usage (5 hours per day).

The cost is tiny. A typical label can read anywhere from $6 for 32-inch LEDs to $38 for 65-inch plasmas (PDF). Per year. That's from 50 cents to $3.18 per month. If that's the definition of chump change to you, you're probably not alone.

That's the primary reason I stopped … Read more

Friday Poll: Is Hawking right about us needing to colonize space?

Stephen Hawking's mind is reaching out into the far depths of space as he contemplates the survival of humanity over the very long term. He doesn't hold out much hope for us here on Earth. Instead, the famous physicist is looking to the stars for an answer.

"We must continue to go into space for humanity. We won't survive another 1,000 years without escaping our fragile planet," Hawking said in a recent lecture, according to the Los Angeles Times.

The delicate nature of Earth and humanity's propensity for steamrolling over the environment both spell doom as far as Hawking is concerned. He has been talking about the need to colonize space for years, but his latest comments have ramped up the discussion.… Read more

Master gravity in Return to Earth

The quirky and cute robot genre has been around for decades. Since the 1980s, when movies featuring robots exploded, and even recently with Disney film "WALL-E" touting the insurmountable spirit of a trash-removing robot, they have captured the imagination of humans everywhere. Return to Earth harnesses that fascination and creates an intriguing, occasionally frustrating game full of challenges and rewards, all with a stubborn little robot at its core.

The concept of the game is simple. Get your robot home from another planet. Levels are set up very similarly to other iOS games. There are dozens of micro … Read more

Space shots: Our beautiful world from far above

Today, the International Space Station gets a change of command as outgoing NASA Commander Kevin Ford transfers leadership of the space lab to Commander Chris Hadfield, the first Canadian astronaut to assume the role. Hadfield and crew will carry out the planned Expedition 35 mission (PDF).

Our gallery below looks back at some the extraordinary images of Earth Hadfield captured with dSLRs during his first few months aboard the space lab (he and Expedition 34 arrived in mid-December). The unique vantage point of the ISS delivers unforgettable vistas, from the astoundingly abstract Australian Outback to a sensational shimmer of gold on the waters of the San Francisco Bay.… Read more

Did Google Earth error send murderer to wrong address?

Sometimes, even after a murder conviction, some see reasonable doubt that the conviction was a righteous one.

Such is the case in the murder of Dennis and Merna Koula in La Cross, Wisc, a quiet community.

Their son Eric was found guilty and is currently serving two consecutive life-sentences for the murder of the wealthy couple.

It was Eric Koula who found the body. It was Eric Koula whose alibi didn't stand up. Eric Koula was broke.

Yet as CBS News' "48 Hours" reported, there are some inconsistencies that some can't quite put aside. They include … Read more

Double asteroid trouble may have wiped out dinosaurs

When asteroids attack, dinosaurs lose. Though there are still competing theories as to why we lost awesome animals like Tyrannosaurus rex and Velociraptors, many scientists look to a long-ago asteroid impact to explain the wipeout.

A study published in Earth and Planetary Science Letters adds a new wrinkle to the asteroid assumption by suggesting that the dinos may have had to contend with not one, but two deadly balls of flying space rock. Titled "Morphology and population of binary asteroid impact craters," the study was lead by Katarina Miljkovic from the Institute of Earth Physics in Paris.

If you look out into space around Earth, you'll find that about 15 percent of asteroids are binary, meaning they're traveling in pairs. However, only 2 to 4 percent of craters on Earth have been labeled as binary impacts. Miljkovic believes this number is under-reported and that many binary asteroids have been overlooked because their craters overlap.… Read more

Take 100,000 more tours inside Google Earth

Last year at Google I/O the company introduced Tour Guide, a feature that provided animated 3D flyovers of popular destinations inside Google Earth, complete with facts about the site in question.

By October, the app had 11,000 tours available. Today Tour Guide got a huge upgrade, with more than 100,000 new tours available for destinations in 200 countries. Google also updated existing tours.

Says Google in a blog post:

The new, richer tours combine 3D flyovers, Wikipedia snippets and - for the first time - place highlight and more than 1 million user-generated Panoramio photos in order … Read more

Europe's space agency kicks off asteroid collision mission

Doomsday isn't far from many people's imaginations, whether it's the end of the Mayan calendar, the rapture, or a massive asteroid smashing into the Earth. Now, one of these far-flung scenarios may become even less likely.

The European Space Agency announced this week that it's in the beginning phases of an "Asteroid Impact and Deflection Mission" with its U.S. partner Johns Hopkins Applied Physics Laboratory. The eventual goal of the mission is to verify whether scientists can collide with an asteroid that's hurtling through space -- so as to avoid any possible … Read more
