Geotags? GPS? Pssh. That's old school. Google has a brand-new trick for figuring out where the photos you've taken happen to be, and it doesn't need any extra data from your camera to do it—just the photo itself, assuming it's not a blurry or otherwise bad shot. Google's program, called PlaNet, isn't perfect, but it's not easy to figure out where an image might have been shot just by its contents. We doubt you could do that, and that's something Google has actually tested via the website GeoGues..>> view originalWhat prehistoric teeth can tell us about our evolutionary ancestors
Researchers have discovered that the evolution of human teeth is much simpler than previous thought.For years scientists have debated the evolution of our third molars, more commonly known as wisdom teeth. While the molars are often very small or fail to even develop in humans, those of other hominin species in our evolutionary tree were huge. Their chewing surfaces could be two to four times larger than those in an average modern human.Many scientists have long tried to explain the profound si..>> view originalNew Pluto photos reveal north pole's frozen canyons
WASHINGTON, Feb. 26 (UPI) -- New images of Pluto's north pole showcase the dwarf planet's unusual canyons. The images were captured by the Multispectral Visible Imaging Camera, or MVIC, on the New Horizons probe. The series of pits and plateaus weaves across a polar region known as Lowell Regio. Most of the canyons are roughly six miles wide. The widest canyon stretches ten miles across. Compared to other canyons systems found on Pluto, those within Lowell Regio are shallower and boast less dra..>> view originalClimate Change is Shifting Natural Resources and Wealth Along With It
As the planet warms, plants, trees, fish and other natural resources are on the move, shifting toward the poles, in the direction of higher elevations and deeper into the seas, states a paper published February 24 in the journal Nature Climate Change. This natural capital has economic value, especially in developing countries where it accounts for a large share of resources. The team of researchers led by Eli Fenichel, an assistant professor at the Yale School of Forestry & Environmental Studi..>> view originalUnprecedented scientific report says bees and other pollinators are in dire need of help

(AP Photo/Toby Talbot) Around the world, the animals that pollinate our food crops — over 20,000 species of bees, butterflies, bats and many others — are the subject of growing attention. An increasing number of pollinator species are thought to be in decline, threatened by a variety of mostly human pressures, and their struggles could pose significant risks for global food security and public health. Until now, most assessments o..>> view originalLIGO Ain't a Gravitational Wave Detector—It's an Observatory
LIGO detected gravitational waves created from the collision between two black holes. The detection was awesome, but let’s look at the name of the detector for a second: Laser Interferometer Gravitational wave Observatory (maybe I should call it LIGWO). LIGO is first and foremost an observatory. It’s a type of telescope that uses gravitational waves instead of electromagnetic waves. I’ve already gone over the methods LIGO uses to determine the distance to the black hole collision, but how do th..>> view originalHumble sea sponge may be the common ancestor of all animal life
Scientists estimate that there are about 8.7 million species of animals on Earth – give or take 1.3 million. But in the beginning there could be only one.That animal was very likely the simple sea sponge, according to a study by researchers at the Massachusetts Institute of Technology in Cambridge.Based on new genetic tests, the team of scientists can say with confidence that molecules produced by sea sponges have been found in 640-million-year-old rocks. These rocks significantly predate the C..>> view original
