A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware.

Have concerns about potential vulnerabilities in your data systems? We hear from three IT security experts about how they solved the systems architecture problems that were keeping them up at night ...

A mathematician was keen to forecast the evolution of the COVID epidemic. Instead, he ended up solving a problem which had troubled computer scientists for decades. During the corona epidemic many of ...

A new wave of “reasoning” systems from companies like OpenAI is producing incorrect information more often. Even the companies don’t know why. Credit...Erik Carter Supported by By Cade Metz and Karen ...

It’s not often that 5-year-olds can grasp questions at the frontiers of computer science, but it can happen. Suppose, for instance, that a kindergartner named Alice has two apples, but she prefers ...

When the Clay Mathematics Institute put individual $1-million prize bounties on seven unsolved mathematical problems, they may have undervalued one entry—by a lot. If mathematicians were to resolve, ...

A CIS major covers many disciplines and applications, and uses the computer as a powerful problem-solving machine.

A technological meltdown left employees of airlines, banks, hospitals and emergency services around the world staring at the dreaded “blue screen of death” on Friday as their computers went inert in ...

Computer science involves much more than writing code. It blends technical knowledge —like programming, algorithms and data systems — with soft skills, such as communication and problem-solving.

Systems like OpenAI’s GPT-5 are accelerating research in math, biology and chemistry. But there is a debate over whether it can do that work on its own. Credit...Agnes Jonas Supported by By Cade Metz ...
