March 23, 2013 The city of Gladstone is the world's fourth largest coal-export hub. It's also a jumping off point to the southern end of the Great Barrier Reef. But coal mining could eventually kill the reef that Australians revere.
March 22, 2013 There's some evidence that carbon dioxide we pump into the atmosphere has slowed the development of coral reefs. So researchers are adding antacid to the water in a tiny part of the Great Barrier Reef, to see whether the corals will grow faster if their water supply is less acidic.
March 20, 2013 Seaweed might not be as flashy as coral, but it plays an important role on the reef. They compete for space, and rising carbon dioxide levels could someday tip the balance of power.
March 19, 2013 The tropical island set in turquoise water just off the Great Barrier Reef is the site of an experiment to see what will happen to coral reefs as the ocean absorbs ever more of the carbon dioxide and heat we've added to our planet's thin skin. The results weren't so pretty.
February 14, 2013 Small amounts of the drugs that people take end up in wastewater and then in streams and rivers. It's usually not enough to harm the health of humans who swim in or drink the water. But there is growing evidence that pharmaceuticals in wastewater may affect wildlife.
February 12, 2013 North Korea's latest nuclear weapons test is much more powerful than the previous two, according to estimates made by instruments that measure seismic waves from the blast. But it's hard to verify North Korea's claim that the test was of a miniaturized nuclear weapon.
January 16, 2013 Land that isn't in good enough condition to grow crops could be used to produce substantial amounts of liquid biofuels, a new study claims. But there are many concerns about the study, and about the future of advanced biofuels in the U.S. and abroad.
January 1, 2013 The discovery of the Higgs boson will likely be hailed as the most important scientific discovery of 2012. But many ideas that change the world don't tend to spring from flashy moments of discovery. Our view of nature — and our technology — often evolve from a sequence of more subtle advances.
