Rapid changes in the Arctic ecosystem from surface to depth during the ice minimum in the summer of 2012.

We were able to demonstrate for the first time that the warming and the associated physical changes in the Central Arctic cause fast reactions in the entire ecosystem down to the deep sea", summarizes lead author Boetius. The deep sea has so far been seen as a relatively inert system affected by global warming only with a considerable temporal delay.

The fact that microbial decomposition processes fueled by the algal deposits can generate anoxic spots in the deep sea floor within one season alarms the researcher: "We do not know yet whether we have observed a one-time phenomenon or whether this high algal export will continue in the coming years." Current predictions by climate models assume that an ice-free summer could occur in the Arctic in the next decades.

===> Boetius and her team warn: "We still understand far too little about the function of the Arctic ecosystem and its biodiversity and productivity, to be able to estimate the consequences of the rapid sea-ice decline.<===

Scientists say there are still many fragments to be found as debate starts over precise nature of celestial object

Curiosity drilled about 0.8 inches (2 centimeters) into a Martian rock called John Klein.

Marcus Eliasson, Arnaud Taffanel, and Tobias Antonsson are the three engineers behind Bitcraze, the startup that launched preorders last week for a palm-sized quadcopter called the Crazyflie Nano.

Water on the moon: It's been there all along

"The surprise discovery of this work is that in lunar rocks, even in nominally water-free minerals such as plagioclase feldspar, the water content can be detected," said Zhang, James R. O'Neil Collegiate Professor of Geological Sciences."It's not 'liquid' water that was measured during these studies but hydroxyl groups distributed within the mineral grain," said Notre Dame's Hui. "We are able to detect those hydroxyl groups in the crystalline structure of the Apollo samples.

Most flexible polymers are inherently flimsy. When you look at their micro-structures it's easy to see why: They look like piles of entangled spaghetti strands.
