A New Link to an Old Model Could Crack the Mystery of Deep Learning

By ANIL ANANTHASWAMY

To help them explain the shocking success of deep neural networks, researchers are turning to older but better-understood models of machine learning.

How Animals Map 3D Spaces Surprises Brain Researchers

By JORDANA CEPELEWICZ

When animals move through 3D spaces, the neat system of grid cell activity they use for navigating on flat surfaces gets more disorderly. That has implications for some ideas about memory and other processes.

Around the Web

Crocodiles Are Enduringly Nosey
Crocodiles have repeatedly evolved the same snout over the eons. Today's crocodile is a "revival of one of evolution's greatest hits," Riley Black writes for Smithsonian Magazine. Nature often reinvents the wheel: Researchers studying the strange neural system of comb jellies have even wondered whether neurons evolved more than once, as Emily Singer reported for Quanta in 2015.

Our Machines, Our Learning
A handful of researchers, including one artist, told Nature how artificial intelligence has helped them accelerate scientific research. Scientists are increasingly turning to artificial intelligence algorithms to find patterns in datasets too massive to comprehend, as Dan Falk reported for Quanta in 2019.
