A sunspot the size of 5 Earths unleashed a spectacular solar flare this week
A NASA satellite tasked with keeping an eye on the sun captured the moment a solar flare burst from the star on Sunday. The “mid-level” flare — seen by NASA’s Solar Dynamics Observatory — erupted from a sunspot five times the size of the Earth. The sunspot is moving out of view of the Earth now due to the sun's rotation. Solar flares are huge eruptions of radiation that burst forth from the star when the sun’s magnetic fields break and release energy. The April 17 flare was classified as an M6...>> view originalGerm Study Finds Each City Has Its Own Microbe Signature
Toronto has the CN Tower, San Diego its parks and waterfronts, Flagstaff its pine-covered mountains. Each city is distinguished by its landmarks, weather and people. And, it seems, by their germs. Researchers who were looking for the best way to measure germs in an office were surprised to find that it's easier to tell apart samples of microbes based on what city they were taken from than any other factor. Researcher John Chase samples office surface materials just prior to install..>> view originalExxon Tries To Bury Climate Documents By Claiming First Amendment Rights
ExxonMobil is fighting a subpoena seeking its internal documents on climate change, arguing that the order violates the company's constitutional rights. It's an argument that legal experts say is unusual but not unprecedented. Earlier this month, U.S. Virgin Islands Attorney General Claude Walker initiated an investigation into whether Exxon misled the public on climate science. His office is also requesting records from the Competitive Enterprise Institute, a Washington, D.C.-based libertarian..>> view originalBright Ceres Crater Looks Like a Stop Sign (Photos)

The rim of Ceres' Haulani Crater is composed of relatively straight lines, making the 21-mile-wide (34 kilometers) f..>> view originalHuman limbs may have gotten their start as gill arches
WOODS HOLE, Mass., April 19 (UPI) -- New genetic evidence suggests the evolutionary origins of human limbs lie in the gill arches of sharks, skates and rays. Gill arches are the collection of looped bones that support gills and serve as the sprouting point for gill arch appendages, or branchial rays. Biologists have suggested gill arches laid the evolutionary foundation for paired fins in early fish, which later paved the way for paired limbs in mammals. Now there's the genetic evidence to back..>> view originalChinese scientists develop mammal embryos in space for first time
Chinese scientists on Sunday said they have successfully developed early-stage mouse embryos in space for the first time on a retrievable microgravity satellite set to return to Earth sometime next week. The SJ-10 research probe, launched on April 6, carried over 6,000 mouse embryos in a self-sufficient chamber the size of a microwave oven, according to Duan Enkui, a researcher with the Chinese Academy of Sciences (CAS). Among them, 600 embryos were put under a high-resolution camera, wh..>> view originalPolls show strong support for climate action, but Congress hasn't acted. What gives?
If you've heard the presidential candidates talk about climate change, you'd probably guess it's one of America's most divisive issues. Hillary Clinton and Bernie Sanders have described global warming as one of the greatest threats facing the United States, while Donald Trump has said he's "not a big believer." Ted Cruz has described climate change as a "pseudoscientific theory" designed by liberals to give government more power.But polls show that a vast majority of Americans believe climate ch..>> view originalUSDA: No regulation of genetically altered mushrooms
