What caused the ice ages? Tiny ocean fossils offer key evidence

The last million years of Earth history have been characterized by frequent "glacial-interglacial cycles," large swings in climate that are linked to the growing and shrinking of massive, continent-spanning ice sheets. These ...

Quantum hall effect 'reincarnated' in 3-D topological materials

U.S. and German physicists have found surprising evidence that one of the most famous phenomena in modern physics—the quantum Hall effect—is "reincarnated" in topological superconductors that could be used to build fault-tolerant ...

Warm ocean water attacking edges of Antarctica's ice shelves

Upside-down "rivers" of warm ocean water are eroding the fractured edges of thick, floating Antarctic ice shelves from below, helping to create conditions that lead to ice-shelf breakup and sea-level rise, according to a ...

Curiosity rover sharpens paradox of ancient Mars (Update)

Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet's surface. Yet, the ancient sun was about one-third less warm and climate modelers ...

Biologists identify unique way catfish locate prey

Animals incorporate a number of unique methods for detecting prey, but for the Japanese sea catfish, Plotosus japonicus, it is especially tricky given the dark murky waters where it resides.

Greenland ice stores liquid water year-round

Researchers at the University of Utah have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. The aquifer is extensive, covering ...
