Did all animal life on Earth begin with a sea sponge?
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 originalOne-year spaceman sees mission as 'steppingstone' to Mars
As soon as he returns from the International Space Station, NASA’s first and only yearlong spaceman, Scott Kelly, will try to pop up from a lying position and stand still for three minutes. He’ll take a crack at a mini-obstacle course and attempt to walk a straight line, heel to toe – all so researchers can see whether he’d hit the ground running if this were Mars instead of Earth. NASA considers it crucial prep work for future Mars explorers who will have to spend much longer in space and won’..>> view originalWhat the heck are gravitational waves?

What the heck are gravitational waves? Here’s the beautiful explanation [VIDEO] February 27, 2016 by Dan Taylor Leave a Comment The discovery of gravitational waves rocked the scientific world in recent weeks -- but what are they? A physicist explains it to Stephen Colbert.The discovery of gravitational waves has been perhaps the biggest moment in science since the discovery of the Higgs boson — but what exactly are they and what makes them so important? A physicist was on the Late Show with St..>> view originalNH has lots of places named Rattlesnake, but almost no rattlesnakes
Massachusetts, as you may have heard, is freaking out over plans to put 150 rattlesnakes on an island in the middle of the state’s biggest reservoir, yet here in New Hampshire we already have a Rattlesnake Island, on Lake Winnipesaukee. Plus we have Rattlesnake Hill in Concord, as well as five other Rattlesnake Hills scattered across the state, not to mention four Rattlesnake Mountains and a Rattlesnake Pond. What don’t we have much of? Rattlesnakes. The only rattlesnake native to New Hampsh..>> view originalScience Report Warns of Fewer Bees - Sci

Climate change pushes fish toward the poles, letting poorer countries closer to the Equator with less vital natural resources. A study published Wednesday in the journal Nature Climate Change revealed that species are migrating away from temperate zones and toward the planet’s North and South poles as global temperatures rise. The team of researchers said that the changing migration patterns of fish will probably raise inequality between the world’s wealthy and disadvantaged. Fish is a critical..>> view originalDoes Planet Nine even exist? NASA's Cassini probe hopes to find out
Does Planet Nine even exist? NASA’s Cassini probe hopes to find out Feb 27, 2016 by Shane Jones Leave a Comment NASA's Cassini probe will now be using its observational prowess to find the elusive Planet Nine, whose existence has only been theorized by scientists. Planet Nine, the elusive, theoretical ninth planet in our solar system whose existence was posited by two Caltech astronomers last month, has remained undiscovered. NASA’s Cassini probe, however, might be able to change all of that, a..>> view originalSpaceX, SES confirm Sunday Falcon 9 rocket launch

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 originalPlaNet, Google's latest AI, has superhuman accuracy with photo locations
Thanks to Google, a new artificial intelligence system is outperforming humans in spotting the origins of images.Google has unveiled a new system to identify where photos are taken. The task, simple when images contain famous landmarks or unique architecture, goes beyond the overt to examine small clues hidden in the pixels.The program, named PlaNet, uses a deep-learning neural network, which means the more images PlaNet sees, the smarter it gets.The impressive part? Its geotagging abilities ar..>> view original
