Hidden Computational Power Found in the Arms of Neurons
The dendritic arms of some human neurons can perform logic operations that once seemed to require whole neural networks.
Toward a Grand Unified Theory of Snowflakes
Snow crystals come in two main types. The “pope” of snowflake physics has a new theory that explains why.
Famous Fluid Equations Spring a Leak
Researchers have spent centuries looking for a scenario in which the Euler fluid equations fail. Now a mathematician has finally found one.
Continents of the Underworld Come Into Focus
Giant blobs nestled deep in the Earth may influence everything from the structure of island chains to mass-extinction events.
No Dark Energy? No Chance, Cosmologists Contend
A study challenged the evidence for the mysterious antigravitational force known as dark energy. Then cosmologists shot back.
Mathematician Proves Huge Result on ‘Dangerous’ Problem
Mathematicians regard the Collatz conjecture as a quagmire and warn each other to stay away. But now Terence Tao has made more progress than anyone in decades.
Why the Laws of Physics Are Inevitable
By considering simple symmetries, physicists working on the “bootstrap” have rederived the four known forces. “There’s just no freedom in the laws of physics,” said one.
How Microbiomes Affect Fear
New studies help to explain how microbes in the gut can shape a host’s fear responses.
Longevity Linked to Proteins That Calm Overexcited Neurons
New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.
Top Dark Matter Candidate Loses Ground to Tiniest Competitor
Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.
