Hidden Chaos Found to Lurk in Ecosystems
New research finds that chaos plays a bigger role in population dynamics than decades of ecological data seemed to suggest.
Computer Science Proof Unveils Unexpected Form of Entanglement
Three computer scientists have posted a proof of the NLTS conjecture, showing that systems of entangled particles can remain difficult to analyze even away from extremes.
Mass and Angular Momentum, Left Ambiguous by Einstein, Get Defined
Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out.
Can Computers Be Mathematicians?
Artificial intelligence has bested humans at problem-solving challenges like chess and Go. Is mathematics research next? Steven Strogatz speaks with mathematician Kevin Buzzard to learn about the effort to translate math into language that computers understand.
Life Helps Make Almost Half of All Minerals on Earth
A new origins-based system for classifying minerals reveals the huge geochemical imprint that life has left on Earth. It could help us identify other worlds with life too.
Controversy Continues Over Whether Hot Water Freezes Faster Than Cold
Decades after a Tanzanian teenager initiated study of the “Mpemba effect,” the effort to confirm or refute it is leading physicists toward new theories about how substances relax to equilibrium.
The Spooky Quantum Phenomenon You’ve Never Heard Of
Quantum computers may derive their power from the “magical” way that properties of particles change depending on the context.
Surfaces So Different Even a Fourth Dimension Can’t Make Them the Same
For decades mathematicians have searched for a specific pair of surfaces that can’t be transformed into each other in four-dimensional space. Now they’ve found them.
The Brain Has a ‘Low-Power Mode’ That Blunts Our Senses
Neuroscientists uncovered an energy-saving mode in vision-system neurons that works at the cost of being able to see fine-grained details.
Astronomers Reimagine the Making of the Planets
Observations of faraway planets have forced a near-total rewrite of the story of how our solar system came to be.
