I actually know the answer to this and it's slightly insane. Google pulls from Wikipedia to determine if a place is a city, town, neighbourhood, whatever. Brighton's first line describes it as a "seaside resort" so Google Maps thinks it's a neighbourhood and doesn't display it in the "city" font.

Reading articles on the amounts HE has spent in APCs over the last 5-10 years, and slowly watching my blood pressure rise. Millions upon millions, on something WE CAN ABSOLUTELY DO OURSELVES FOR A FRACTION OF THE COST - what universities couldn't do with that kind of money now... 😠 And breathe...

At today's UKRI board meeting, the fate of UK particle physics and astronomy will likely be decided. Have we done enough to convince the powers-that-be to halt the proposed funding cuts? 🤞 Read Prof. Hiranya Peiris in Nature today eloquently explaining why these cuts are wrong.🧪🔭⚛️ 📖: rdcu.be/friwM

Restructuring research funding as a choice between discovery and application gets the economics wrong, the evidence wrong and the people wrong.

A premise is gaining traction in science policy on both sides of the Atlantic: that fundamental and applied research are competing claims on the same budget, and that the balance must shift towards application. In the USA, the current administration has proposed cuts of billions of dollars to the National Institutes of Health and the National Science Foundation. In the UK, the national funding agency UK Research and Innovation (UKRI) is restructuring its portfolio around government growth priorities, with curiosity-driven research nominally protected but the grant lines that actually fund investigators under severe pressure. The language varies — ‘doing fewer things better’, ‘aligning research with industrial strategy’ — but the underlying logic is the same. Fundamental science, the argument goes, is a luxury that becomes dispensable when budgets are tight. This premise is wrong, and the consequences of acting on it are already visible.

Stars of physics are in Westminster right now to call on the Government to halt funding cuts to astronomy and particle physics research. Professor Brian Cox called them "inexplicable", urging the Government to instead "trust, inspire and continue to invest in the next generation of scientists".

Letter in today's Times by climate scientist Sir Brian Hoskins: "The discourse around net-zero is increasingly decoupled from…science and our changing weather. "Net-zero is not an arbitrary slogan, rather it is dictated by the laws of physics."

When you see the story about how the world now has its first trillionaire, and when you see the story about how laboratories in Congo have run out of supplies to test for Ebola, it is important to understand that in many ways these are the same story.

"There was never an agreement to give the US sovereignty over the internet. We are still inside UK borders when we use the internet. The infrastructure is here. The revenue is made here. The internet is eminently governable."

A teen social media ban is an admission of total and utter failure to govern online spaces

The UK government is currently calling for steps that fall short of a teen social media ban. Here's why it shouldn't take the next step.

What you see in the Sun, is the Chicago skyline from the Indiana Dunes beach, across Lake Michigan. You can see it from 50 miles of distance due to a form of superior mirage, because the skyline is seen above where it's actually located. [📷 wesskywalker]

I'm not saying this because I particularly think he should stand for leader but it does feel Quite Interesting that Labour actually has this other mayor who's been successfully running a much bigger city for a longer period of time but for some reason no one's waiting for him to save the party

Very happy to see the last work of Sindre Brattegard’s PhD out on arXiv! 🥳 Around 2 years ago, during a (mostly non-scientific) visit by my friend Stephanie Matern to Dublin, we asked the question of how finite reservoirs could be useful for thermometry 👇 arxiv.org/abs/2604.28155

Optimal current-based sensing of phonon temperature using a finite reservoir

In realistic nanoscale transport set-ups, electron-phonon coupling leads to the exchange of heat between phonon baths and electronic reservoirs with finite heat capacities. Such exchange affects the f...

"Photo 51" was the X-ray diffraction pattern that revealed the internal structure of DNA, produced by PhD student Raymond Gosling working under Rosalind Franklin's direction at King's College in London in 1952. Let's talk about how CORK & a PAPERCLIP played a central role in DNA's discovery.

Significant day for UK trade policy. With the announcement of the EU-Australia FTA the UK now only has an FTA where the EU doesn't with Malaysia and Brunei as part of CPTPP. The EU meanwhile has a deal with Brazil, Argentina, Uruguay and Paraguay that the UK doesn't.

Something of a Friday 13th for the science department today - Chi Onwurah has lambasted Patrick Vallance over "wholly unacceptable" physics cuts - The NAO has reported a £5.6bn repair backlog to uni infrastructure - MPs have said regional growth is suffering from poor data on R&D spending 🧵 ...

Mathematician Georg Cantor was born #OTD in 1845. He is the founder of set theory and developed the concepts of cardinal and transfinite numbers. These shocking results led his former professor Kronecker to call him a "corrupter of youth." Image: Oberwolfach Photo Collection
