EXCLUSIVE: Reform UK just broke electoral law in Gorton and Denton.

The party confirmed they sent out campaign materials without proper party imprint, something it insists was a mistake.

In Manchester, productivity is up, demand for office space in the city centre is climbing, and the population continues to grow at a lick. Why does such an economically successful city not have its statement businesses? And should we even care?

The university funding crisis finally starting to make it into newspaper editorials
www.ft.com/content/82f5...

With universities making a loss on teaching domestic graduates, and almost half of universities in England facing deficits this year, student loans need to be reviewed as part of a much broader, and urgent, rethink of how UK universities are funded.

Excellent article but stark reminder that for all the perceptions of universities as ivory towers for elites, they are actually vital hubs in towns n cities supporting local businesses and providing key services as well as education….

‘If I think about what this means, I want to cry’: what happens when a city loses its university?

When Essex University’s Southend campus opened, it was a message of hope for a ‘left behind’ UK seaside town. Its closure will be felt far beyond its 800 students, some of whom will not get their degr...

Interesting paper, especially interesting it's coming from researchers at Anthropic arxiv.org/pdf/2601.20245

How AI Impacts Skill Formation
Judy Hanwen Shen∗ Alex Tamkin†
February 3, 2026
Abstract
AI assistance produces significant productivity gains across professional domains, particularly for
novice workers. Yet how this assistance affects the development of skills required to effectively supervise
AI remains unclear. Novice workers who rely heavily on AI to complete unfamiliar tasks may compromise
their own skill acquisition in the process. We conduct randomized experiments to study how developers
gained mastery of a new asynchronous programming library with and without the assistance of AI.
We find that AI use impairs conceptual understanding, code reading, and debugging abilities, without
delivering significant efficiency gains on average. Participants who fully delegated coding tasks showed
some productivity improvements, but at the cost of learning the library. We identify six distinct AI
interaction patterns, three of which involve cognitive engagement and preserve learning outcomes even
when participants receive AI assistance. Our findings suggest that AI-enhanced productivity is not a
shortcut to competence and AI assistance should be carefully adopted into workflows to preserve skill
formation – particularly in safety-critical domains.

Is competition always the hero?

We compete for schools & jobs, while economists praise market competition for better choices.

But cases like SHEIN, Palantir, Samsung, & Boeing suggest competition can sometimes do more harm than good.
