Dozens of new viruses discovered in 15,000-year-old glacier ice

Scientists have collected viruses from almost-15,000-year-old ice samples, taken from glaciers on the Tibetan Plateau. Dozens of species were found to be unknown to science, which could provide an intriguing look back at the history of viral evolution….

Surprisingly high mercury levels detected in Greenland glacier meltwater

The Greenland Ice Sheet is associated with a range of environmental issues, but now researchers have discovered a surprising new problem that hadn’t been considered before. Glacial meltwater was found to be unexpectedly high in mercury, which could hav… Continue reading Surprisingly high mercury levels detected in Greenland glacier meltwater

How Can Heavy Metal Fly?

Scientists found a surprising amount of lead in a glacier. They were studying atmospheric pollution by sampling ice cores taken from Alpine glaciers. The surprising part is that they found more lead in strata from the late 13th century than they had in those deposited at the height of the …read more

Declassified spy satellite photos reveal accelerating ice loss at Earth's "third pole"

Recently declassified US spy satellite images reveal Himalayan glaciers have been melting at an accelerating rate

It’s not entirely news that the Earth’s ice budget is under threat from a warming climate, but a new study has looked into just how fast that’s happening. Using recently declassified spy satellite photos, researchers found that compared to the last quarter of the 20th century, Himalayan glaciers have been melting twice as fast this century. In a rare piece of good news, a separate study has shown that a Greenland glacier has gained ice for the third year in a row.

10,000-Year-Old Camera Lens Takes Striking Pictures

The first photograph was taken sometime in the early 1800s, and through almost two centuries of development we’ve advanced through black-and-white, the video camera, and even high-speed cameras that can take thousands of frames per second. [Mathieu Stern] took a step back from all of the technological progress of the past two hundred years, though, and found a lens for his camera hidden in the glacial ice of Iceland.

Ice in this part of the world has been purified over the course of 10,000 years, and [Mathieu] realized that with this purity the ice could be formed into a workable …read more
