[:es]The Algorithm That Lets Particle Physicists Count Higher Than Two[:]

Through his encyclopedic study of the electron, an obscure figure named Stefano Laporta found a handle on the subatomic world’s fearsome complexity. His algorithm has swept the field.

[:es]To Be Energy-Efficient, Brains Predict Their Perceptions[:]

Results from neural networks support the idea that brains are “prediction machines” — and that they work that way to conserve energy.

[:es]A New Theory for Systems That Defy Newton’s Third Law[:]

In nonreciprocal systems, where Newton’s third law falls apart, “exceptional points” are helping researchers understand phase transitions and possibly other phenomena.

[:es]Mathematicians Find Structure in Biased Polynomials[:]

New work establishes a tighter connection between the rank of a polynomial and the extent to which it favors particular outputs.

[:es]The Brain Can Recall and Reawaken Past Immune Responses[:]

The brain not only helps to regulate immune responses, but also stores and retrieves “memories” of them.

[:es]Researchers Revise Recipe for Building a Rocky Planet Like Earth[:]

Over the past decade, researchers have completely rewritten the story of how gas giants such as Jupiter and Saturn form. They’re now debating whether the same process might hold for Earth.

[:es]Is the Great Neutrino Puzzle Pointing to Multiple Missing Particles?[:]

Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the universe, and other mysteries.
