The Year in Math and Computer Science

December 21, 2018

Several mathematicians under the age of 30 left their marks all over the field, and amateur problem-solvers of all ages made significant contributions to long-dormant puzzles.

Milestone Experiment Proves Quantum Communication Really Is Faster

December 19, 2018

In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.

Mathematicians Seal Back Door to Breaking RSA Encryption

December 17, 2018

Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work.

Mathematical Simplicity May Drive Evolution’s Speed

November 29, 2018

Some researchers are using a complexity framework thought to be purely theoretical to understand evolutionary dynamics in biological and computational systems.

Graduate Student Solves Quantum Verification Problem

October 8, 2018

Urmila Mahadev spent eight years in graduate school solving one of the most basic questions in quantum computation: How do you know whether a quantum computer has done anything quantum at all?

Machine Learning Confronts the Elephant in the Room

September 20, 2018

A visual prank exposes an Achilles’ heel of computer vision systems: Unlike humans, they can’t do a double take.

New AI Strategy Mimics How Brains Learn to Smell

September 18, 2018

Machine learning techniques are commonly based on how the visual system processes information. To beat their limitations, scientists are drawing inspiration from the sense of smell.

The New Science of Seeing Around Corners

August 30, 2018

Computer vision researchers have uncovered a world of visual signals hiding in our midst, including subtle motions that betray what’s being said and faint images of what’s around a corner.

Universal Method to Sort Complex Information Found

August 13, 2018

The nearest neighbor problem asks where a new point fits into an existing data set. A few researchers set out to prove that there was no universal way to solve it. Instead, they found such a way.
