London Ulez reduced nitrogen dioxide to legal limit, mayor says The mayor of London says the fall in airborne toxins is due to the Ultra low emission zone expansion.

184 years earlier than predicted, London has met the legal limits for toxic NO2 for the first time.

This historic milestone proves that bold action like expanding ULEZ works, protecting childrenโ€™s health and giving millions cleaner air to breathe.

I suppose this is the point when I should say again that:

the amount of money the videogames industry brings into the UK economy every year is *more than double* the value of the fishing and steel industries *combined*

what this country is really good at is producing culture

The Illusion of Thinking: Understanding the Strengths and Limitations of Reasoning Models via the Lens of Problem Complexity Recent generations of frontier language models have introduced Large Reasoning Models (LRMs) that generate detailed thinking processesโ€ฆ

There's a lot of big news today/this week, but Apple just dropped a nuke of a paper about LLMs & LRMs, specially around "high-complexity tasks where both models experience complete collapse." This is the biggest sign yet that if AI ever lives up the hype, it won't be via those approaches:

I thoroughly enjoyed the EEE Alumni Event organized by @imperialeee.bsky.social Itโ€™s inspiring to hear successful young professionals with a PhD with us speak openly also about their personal failures and rejections. When such honesty comes from accomplished individuals, it feels even more powerful.

I got fooled by AI-for-science hypeโ€”here's what it taught me I used AI in my plasma physics research and it didnโ€™t go the way I expected.

This is a good article. It's so easy to generate results with AI tools that we are rushing to publish them without doing the hard work of checking that they really hold up. This problem predates AI though. So much computational modelling has the same problems

Characterizing finely the decay of eigenvalues of kernel matrices: many people need it, but explicit references are hard to find. This blog post reviews amazing asymptotic results from Harold Widom (1963!) and proposes new non-asymptotic bounds.
