At the Dawn of Life, Heat May Have Driven Cell Division
A mathematical model shows how a thermodynamic mechanism could have made protocells split in two.

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.

How Quantum Computers Will Correct Their Errors
Quantum bits are fussy and fragile. Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine.

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.

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.

Sponge Genes Hint at the Origins of Neurons and Other Cells
A new study of gene expression in sponges reveals the complex diversity of their cells as well as some possibly ancient connections between the nervous, immune and digestive systems.

An Ultra-Precise Clock Links the Quantum World With Gravity
Time was found to flow differently between the top and bottom of a single cloud of atoms. Physicists hope that such a system will one day help them combine quantum mechanics and Einstein’s theory of gravity.

A Hint of Dark Matter Sends Physicists Looking to the Skies
After a search of neutron stars finds preliminary evidence for hypothetical dark matter particles called axions, astrophysicists are devising new ways to spot them.

Neuron Bursts Can Mimic Famous AI Learning Strategy
A new model of learning centers on bursts of neural activity that act as teaching signals — approximating backpropagation, the algorithm behind learning in AI.
