Tardigrade

 

Tardigrades are known to be able to go for decades without food or water, to survive temperatures from near absolute zero to well above the boiling point of water, to survive pressures from near zero to well above that on ocean floors, and to survive direct exposure to dangerous radiations.

Isolated for 5.5 million years: the bizarre beasts of Romania’s poison cave

In the south-east of Romania, in Constanța county close to the Black Sea and the Bulgarian border, there lies a barren featureless plain. The desolate field is completely unremarkable, except for one thing.
Below it lies a cave that has remained isolated for 5.5 million years. While our ape-like ancestors were coming down from the trees and evolving into modern humans, the inhabitants of this cave were cut off from the rest of the planet.
Despite a complete absence of light and a poisonous atmosphere, the cave is crawling with life. There are unique spiders, scorpions, woodlice and centipedes, many never before seen by humans, and all of them owe their lives to a strange floating mat of bacteria.

The future of Anchorage

That’s because, although Anchorage is experiencing unusually balmy winters right now, the city is positioned to actually benefit from climate change. “Alaska is going to be the next Florida by the end of the century,” Camilo Mora, a University of Hawaii geographer told The New York Times last year. A study he published in Nature backed that idea up by suggesting that Anchorage won’t face extreme temperatures until 2071.

Measuring crop yields from space

A research team, led by Kaiyu Guan, a postdoctoral fellow in Earth system science at Stanford’s School of Earth, Energy, & Environmental Sciences, has developed a method to estimate crop yields using satellites that can measure solar-induced fluorescence, a light emitted by growing plants. The team published its results in the journal Global Change Biology.
