The world's oceans are turning acidic at what could be the fastest pace of any time in the past 300 million years, even more rapidly than during a monster emission of planet-warming carbon 56 million years ago, scientists said on Thursday. Looking back at that bygone warm period in Earth's history could offer help in forecasting the impact of human-spurred climate change, researchers said of a review of hundreds of studies of ancient climate records …

British scientists have developed a system to help protect navigation and communications satellites from potentially devastating solar storms, they said on Friday. Services spanning everything from mobile phones to sophisticated weaponry increasingly depend on global positioning system, or GPS, technology.

Australian researchers Thursday revealed they had filmed a pod of extremely rare Shepherd's beaked whales for the first time ever. The Australian Antarctic Division team was tracking blue whales off the coast of Victoria state last month when they spotted the reclusive mammals, which are so rarely seen that no population estimates of the species exist. Voyage leader Michael Double said the black and cream-coloured mammals with prominent dolphin-like …
