Chaos Researchers Can Now Predict Perilous Points of No Return
A custom-built machine learning algorithm can predict when a complex system is about to switch to a wildly different mode of behavior.
Reshuffled Rivers Bolster the Amazon’s Hyper-Biodiversity
The lush biodiversity of the Amazon may be due in part to the dynamics of branching rivers, which serve as invisible fences that continuously barricade and merge bird populations.
Wildfires of Varying Intensity Can Be Good for Biodiversity
The spate of furious wildfires around the world during the past decade has revealed to ecologists how much biodiversity and “pyrodiversity” go hand in hand.
A Physicist’s Approach to Biology Brings Ecological Insights
The physicist Jeff Gore tests theories about microbe communities experimentally and finds new rules governing ecological stability.
He Found ‘Islands of Fertility’ Beneath Antarctica’s Ice
John Priscu’s search for life that thrives under ice took him to subglacial lakes at the South Pole. Now he has his eye on Mars and Europa.
Random Search Wired Into Animals May Help Them Hunt
The nervous systems of foraging and predatory animals may prompt them to move along a special kind of random path called a Lévy walk to find food efficiently when no clues are available.
