Scientists: Climate change occurring 10 times faster than at any time in past 65 million years
Not only is the planet undergoing one of the largest climate changes in the past 65 million years, Stanford climate scientists Noah Diffenbaugh and Chris Field report that it's occurring at a rate 10 times faster than any change in that period.

This spiny, worm-like creature had relatives all around the world
The 505-million-year-old Burgess Shale in Canada's Yoho National Park is famous for its bizarre marine animal fossils, most of which are thought to be found nowhere else on the planet. But a recent study led by University of Toronto ecology & evolutionary biologist Jean-Bernard Caron and published in the July 31 issue of the British scientific journal Proceedings of the Royal Society B suggests that one of its most famous animals had relatives spanning the globe.

Aquatic playground can turn water tanks into fish schools
Juvenile Atlantic salmon raised in tanks with hiding places and floating artificial plants showed signs of improved brain function and could better navigate mazes than the salmon reared in standard hatchery tanks. The discovery may help fish hatcheries raise a smaller number of fish that can better survive in the wild.

Mangroves could survive sea-level rise if protected
Human activity is currently a bigger threat to mangroves, and the natural defences they provide against storm surges and other coastal disasters, than rising sea levels, according to a new study.

Santa’s workshop not flooded - but lots of melting in the Arctic
Santa's workshop at the North Pole is not under water, despite recent reports. A dramatic image captured by a University of Washington monitoring buoy reportedly shows a lake at the North Pole.

The accelerating invader: super-speedy cane toads on the frontline
Studies that only track established populations of invasive species can underestimate the rate at which they can spread into new territory, researchers from the University of Sydney have concluded. "Animals at the vanguard of an invasion can move twice as far as the animals already in a region," said Associate Professor Rick Shine , from the University's School of Biological Sciences.

A response to Methane Mischief: Misleading Commentary Published In Nature
The 24 July news story about the potential cost of Arctic methane release has provoked widespread coverage, including a critique in the Washington Post. Here, Professor Peter Wadhams responds to some of the comments that were made. The 25 July post by Jason Samenow on the global economic impacts of methane emissions in the East Siberian Sea portrays the findings of our research as misleading, a statement with which I strongly disagree.

Coastal Antarctic Permafrost Melting Faster Than Expected
AUSTIN, Texas — For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable.

Cost of Arctic methane release could be ’size of global economy’ warn experts
Economic modelling shows that the possible methane emissions caused by shrinking sea ice from just one area of the Arctic could come with a global price tag of 60 trillion dollars - the size of the world economy in 2012.

Most flammable boreal forests in North America become more so
The magenta-flowered fireweed, which springs up after a burn, dominates a landscape once covered in black spruce in Alaska's Yukon Flats. CHAMPAIGN, Ill. A 2,000-square-kilometer zone in the Yukon Flats of interior Alaska - one of the most flammable high-latitude regions of the world, according to scientists - has seen a dramatic increase in both the frequency and severity of fires in recent decades.

Nighttime heat waves quadruple in Pacific Northwest
Nighttime heat waves are becoming more frequent in western Washington and Oregon. And if you don't sleep well in hot weather, this might be a good time to buy a fan, since records show that on average heat waves tend to strike around the last week of July. University of Washington research shows that the region west of the Cascades saw only three nighttime heat waves between 1901 and 1980, but that number quadrupled to 12 nighttime heat waves in the three decades after 1980, according to a paper published in the July issue of the Journal of Applied Meteorology and Climatology.

Boldly Illuminating Biology’s "Dark Matter"
Is space really the final frontier, or are the greatest mysteries closer to home? In cosmology, dark matter is said to account for the majority of mass in the universe, however its presence is inferred by indirect effects rather than detected through telescopes.

From flounders to seahorses: Evolutionary success of spiny-rayed fishes detailed
Even as the dinosaurs were becoming extinct 66 million years ago, the ancient ancestor of spiny-rayed fishes flourished, eventually giving rise to tens of thousands of species that can now be found in home aquariums or on dinner plates.

Even Zombies Need an Agent
While getting to the bottom of the zombie ant phenomenon, biologist David Hughes is taking calls from Hollywood-and gaining new insights into the role of behavior in the spread of disease. It may sound like science fiction, but the body snatchers are for real. David Hughes has seen them, and trailed them from the jungles of Thailand to the woodlands of South Carolina.

Phytoplankton social mixers
Tiny ocean plants use turbulence for travel to social gatherings. Tiny ocean plants, or phytoplankton, were long thought to be passive drifters in the sea - unable to defy even the weakest currents, or travel by their own volition. In recent decades, research has shown that many species of these unicellular microorganisms can swim, and do so to optimize light exposure, avoid predators or move closer to others of their kind.
