By making use of randomness, a team has created a simple algorithm for estimating large numbers of distinct objects in a stream of data.
Strangely Curved Shapes Break 50-Year-Old Geometry Conjecture
Mathematicians have disproved a major conjecture about the relationship between curvature and shape.
How ‘Idle’ Egg Cells Defend Their DNA From Damage
How do immature egg cells maintain genetic quality for decades before they mature? Scientists find unusual safeguards in this quiescent cell that may inform research into fertility.
Game Theory Can Make AI More Correct and Efficient
Researchers are drawing on ideas from game theory to improve large language models and make them more consistent.
Will Better Superconductors Transform the World?
Scientists are pursuing materials that can conduct electricity with perfect efficiency under ambient conditions. In this episode, the physicist Siddharth Shanker Saxena tells co-host Janna Levin about what makes this hunt so difficult and consequential.
New AI Tools Predict How Life’s Building Blocks Assemble
Google DeepMind’s AlphaFold3 and other deep learning algorithms can now predict the shapes of interacting complexes of protein, DNA, RNA and other molecules, better capturing cells’ biological landscapes.
Dogged Dark Matter Hunters Find New Hiding Places to Check
Perhaps dark matter is made of an entirely different kind of particle than the ones physicists have been searching for. New experiments are springing up to look for these ultra-lightweight phantoms.
