Thawing permafrost feeds climate change
AGU
Carbon, held in frozen permafrost soils for tens of thousands of years, is being released as Arctic regions of the Earth warm and is further fueling global climate change, according to a new study. The new research finds that single-cell organisms called microbes are rapidly devouring the ancient carbon being released from thawing permafrost soil and ultimately releasing it back into the atmosphere as carbon dioxide.

Cheesy, metallic, sweet: 170-year-old champagne is clue to winemaking's past
Nature
When Philippe Jeandet sampled what is probably the oldest champagne ever tasted, he was allowed just one droplet squirted from a microsyringe. Divers retrieved 168 bottles of the 170-year-old champagne from the bottom of the Baltic Sea in an unprecedented haul in 2010, but only 2 millilitres of the drink reached Jeandet's laboratory for analysis.

Did diamond-bearing orangeites originate from MARID-veined peridotites in the lithospheric mantle?
Nature
Kimberlites and orangeites are small-volume igneous rocks occurring in diatremes, sills and dykes. They are the main hosts for diamonds and are of scientific importance because they contain fragments of entrained mantle and crustal rocks, thus providing key information about the subcontinental lithosphere.

Oldest fossils controversy resolved
University of Bristol via ScienceDaily
New analysis of world-famous 3.46-billion-year-old rocks is set to finally resolve a long running evolutionary controversy. The new research shows that structures once thought to be Earth's oldest microfossils do not compare with younger fossil candidates but have, instead, the character of peculiarly shaped minerals.

Yellowstone supervolcano: Magma reservoir big enough to fill Grand Canyon 11 times discovered
International Business Times
Yellowstone supervolcano has a magma reservoir four times bigger than its chamber that we did not know about. The massive reservoir sits below the magma chamber at a depth of between 12 and 28 miles. It has so much magma that it could fill the Grand Canyon 11.2 times. It is believed to be the biggest magma reservoir in the world with a volume of 46,000 km3.

Climate change could harm marine life for millennia
Discovery News
Climate change may lead to disturbances in marine life that will take thousands of years to recover from, not hundreds of years as previously thought, researchers said. The study in the Proceedings of the National Academy of Sciences is based on a section of fossilized ocean fauna found on the seafloor off the coast of California dating to between 3,400 and 16,100 years ago.
