Technique spots warning signs of extreme events
September 22, 2017 04:59 PM - Massachusetts Institute of Technology

Many extreme events — from a rogue wave that rises up from calm waters, to an  instability inside a gas turbine, to the sudden extinction of a previously hardy wildlife species — seem to occur without warning. It’s often impossible to predict when such bursts of instability will strike, particularly in systems with a complex and ever-changing mix of players and pieces.

USDA-funded study finds no-tillage alone not sufficient to prevent water pollution from nitrate
September 22, 2017 04:50 PM - Indiana University

A new IUPUI study funded by the U.S. Department of Agriculture answers a long-debated agricultural question: whether no-tillage alone is sufficient to prevent water pollution from nitrate. The answer is no.
