Good luck to our former Chancellor Ruby Wax as she embarks on bush tucker trials and jungle adventures in I'm a Celebrity... Get Me Out of Here! 🐍

Could Ruby be swapping her cap and ceremonial mace for a crown and sceptre?

New 'state of climate action' report gives you a much better picture than daily headlines about contextless solar panel or EV sales

I'd love to see someone try to estimate just how much time and money has gone into research that is either fully undermined by reliance on LLMs or fully pointless --- because obvious if you start from an understanding of what LLMs actually are.

www.pnas.org/doi/10.1073/...
Screen cap from linked article, with heading Significance and then text: Large Language Models (LLMs) are used in evaluative tasks across domains. Yet, what appears as alignment with human or expert judgments may conceal a deeper shift in how “judgment” itself is operationalized. Using news outlets as a controlled benchmark, we compare six LLMs to expert ratings and human evaluations under an identical, structured framework. While models often match expert outputs, our results suggest that they may rely on lexical associations and statistical priors rather than contextual reasoning or normative criteria. We term this divergence epistemia: the illusion of knowledge emerging when surface plausibility replaces verification. Our findings suggest not only performance asymmetries but also a shift in the heuristics underlying evaluative processes, raising fundamental questions about delegating judgment to LLMs. Sentence starting with "While models often" is highlighted in blue.

While infection control and cleaning is always a good thing, it’s not going to cut it for measles. Measles is airborne and highly contagious. The best approach is vaccination, and local infection control should focus on ventilation and air cleaning www.theguardian.com/society/2025...

The swifts will start to leave in numbers soon. We won’t see them go. And then, obviously, the countdown will begin again.
A graph showing reports of swifts in Britain. The line rises sharply through the first half of May, then more steadily until it peaks in late June. Then a sharp drop off from mid-July until mid-September, when it reaches zero.

Our researchers have found that insomnia could be part of the reason why adults with ADHD traits report having a lower quality of life.

These traits were associated with worse depression, more severe insomnia, and lower sleep quality.
