The Antarctic ozone hole has finally started to 'heal,' scientists report

(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 originalGoodbye Penguins? Antarctica Could Lose Its Adélie Penguins Due To Climate Change
Jul 01, 2016 05:41 AM EDT Adélie penguins (Psygoscelis adeliae) are incredibly resilient birds, having survived the harsh Antarctica conditions for nearly 45,000 years. But a new research suggests that the present changing climate--much of it is human-induced--may wipe out many of their colonies in the icy continent. The study from researchers from the University of Delaware discovered that up to 60 percent of the Adélie penguin population could be killed off by 2099 due to habitat loss.

A team of over 100 Nobel laureates have, in an open letter to Greenpeace, urged the environmental group to “cease and desist” its campaign against genetically modified crops and food. In the letter, released Thursday, the Nobel laureates singled out Greenpeace’s opposition to “Golden Rice” — a strain of genetically modified rice that contains a gene that boosts the production of vitamin A precursor beta-carotene.“Organizations opposed to modern plant breeding, with Greenpeace at their lead, have..>> view originalNonstop Flight: How The Frigatebird Can Soar For Weeks Without Stopping

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 originalTomb with a View: Ancient Burial Sites Served as 'Telescopes'

Astronomers suggest these ancient structures may have been used for observing the night sky and tracking the movements of the stars.

The brightest area on Ceres, located in the mysterious Occator Crater, has the highest concentration of carbonate minerals ever seen outside Earth, according to a new study from scientists on NASA's Dawn mission. The study, published online in the journal Nature, is one of two new papers about the makeup of Ceres. "This is the first time we see this kind of material elsewhere in the solar system in such a large amount," said Maria Cristina De Sanctis, lead author and principal investigat..>> view original
