This false-color image shows ozone concentrations above Antarctica on Oct. 2, 2015. (Credits: NASA/Goddard Space Flight Center) In a major new paper in the influential journal Science, a team of researchers report strikingly good news about a thirty year old environmental problem. The Antarctic ozone “hole” — which, when it was first identified in the mid-1980s, focused public attention like few other pieces of environmental news — has begun, in their words, to finally “heal.” “If you use th..>> view original6000-year-old tomb may have been used as prehistoric telescope
A team of British astronomers might have discovered new insights into how prehistoric humans gazed up at the stars. The researchers are studying what could be the first-ever telescope used by people some 6,000 years ago. A series of long entrance passageways that lead into megalithic, or stone, tombs may have enhanced what these early communities could see shining up in the nighttime sky, according to a release from the Royal Astronomical Society.The researchers are looking to so-called "passag..>> view originalThe imploding cabal to criminalize climate dissent
New York Attorney General Eric Schneiderman and his fellow greenies are getting a lesson about the dangers of believing their own propaganda. These know-it-alls claim there’s a “consensus” on climate change and what to do about it. And they believe that consensus is so broad that even prosecuting dissent would be a slam-dunk. Claude Walker’s monumental crash-and-burn this week blew up that theory. Schneiderman and his ideological pals, from Al Gore to Hillary Clinton, would be wise to take not..>> view originalThe rocks on Mars suggest it used to look like Earth. What happened?

The rocky crests of cliffs and hills reflected in the still water below. The landscape would have been familiar, except for its eerie desolation; nothing on the entire planet moved but the sands shifting in the wind. This was Mars, circa maybe 4 billion years ago. Or at least, it's one vision of Mars painted by Nina Lanza, a researcher at ..>> view originalNonstop Flight: How The Frigatebird Can Soar For Weeks Without Stopping

For millions of years the Adélie penguins have thrived within the natural ebb and flow of temperatures on the Antarctic continent. During colder periods, when glaciers would expand to cover the penguins' preferred rocky breeding grounds, the species' colonies would relocate. During warmer periods when glacier ice would melt, revealing the rocky earth, the penguin colonies would return to old nesting areas.But this way of life may no longer be sustainable for these penguins, according to a study..>> view originalNobel laureates urge Greenpeace to stop opposing GMOs
WASHINGTON – More than 100 Nobel laureates called on the international environmental group Greenpeace on Thursday to end its opposition to genetically modified crops, saying there is a scientific consensus they are safe and can benefit society. At a news conference, the scientists cited in particular the value of a genetically modified rice used to prevent some illnesses related to vitamin A deficiency in much of the developing world. "Golden Rice" produces beta carotene in the grain, which ri..>> view originalNASA's Juno and JEDI prepare to unlock the mysteries of Jupiter
