US nuclear-fusion lab enters new era: achieving ‘ignition’ over and over

Researchers at the National Ignition Facility are consistently creating reactions that make more energy than they consume.

By Jeff Tollefson

In December 2022, after more than a decade of effort and frustration, scientists at the US National Ignition Facility (NIF) announced that they had set a world record by producing a fusion reaction that released more energy than it consumed — a phenomenon known as ignition. They have now proved that the feat was no accident by replicating it again and again, and the administration of US President Joe Biden is looking to build on this success by establishing a trio of US research centres to help advance the science.

DeepMind AI outdoes human mathematicians on unsolved problem

Large language model improves on efforts to solve combinatorics problems inspired by the card game Set.

The card game Set has long inspired mathematicians to create interesting problems.

Now, a technique based on large language models (LLMs) is showing that artificial intelligence (AI) can help mathematicians to generate new solutions.

How working out your ageotype could help you live healthier for longer

Your body is ageing down one of four – or more – possible pathways. Figuring out your “ageotype” could help you zero in on the things you can do to stay healthier for longer

By Graham Lawton

THERE is a (probably apocryphal) story about Henry Ford sending agents out to junkyards across the US in search of scrapped Model Ts. The famous industrialist wanted to know which of the car’s vital components failed first, so he could do something about it. The agents reported back that every bit of the car was susceptible to failure, but some were more susceptible than others, except for one – a component of the steering system called the kingpin, which almost never failed. They expected Ford to announce plans to extend the working lives of the weaker components. Instead, he ordered his engineers to make less resilient kingpins. No point wasting good money on a component that always outlived the others.

Energy / Technology: How Close Is Fusion Power?

For the first time, US scientists have achieved a fusion reaction with net energy gain. But the dream of limitless zero-carbon energy is still a long way from reality.
