Warwick's recent rebrand is also largely purple

As someone who's had a Green MP since before it was cool, I'm surprised that in all the discussion of policy platforms, nobody's mentioning that the Greens have a record of being absolutely fantastic constituency MPs.

Same pattern in the website search bar. I guess the main branding challenge is to avoid confusion with the other UCL. So it's weird that they went with purple.

Terry really hit it out of the park with this post. I even posted it on the bulletin board outside my office. I'm making time today to rekindle my joy.

Apart from much else, the naming of this tool defames the guy who said, "The value of a college education is not the learning of many facts but the training of the mind to think".

"To build on a tool such as edgeR, which is 16+ years in the making and consists of a complex codebase with thousands of lines of code, would previously have required years of study and effort". In his blogpost @lpachter.bsky.social explains how he ported all of it from R and C to Python in a week.

I was a postdoc in Basel for 3.5 years and never got round to trying skiing. Still highly recommend Switzerland.

Google's AI Overview says, "Selective sweep probabilities in spatially expanding populations, such as in growing tumours or biological invasions, are generally independent of the mutation rate and determined by the ratio of mutant-to-wildtype radial expansion speeds, with the probability approximated by \((1-c_{wt}/c_{m})^{d}\) (where \(d\) is the spatial dimension)." These are new results that we reported for the first time in our preprint.

I just returned the proof of our paper "Selective sweep probabilities in spatially expanding populations". Google's AI Overview is already reporting the main results (presumably scraped from the November 2023 preprint) as established fact.

Although I strongly sympathise with US-based colleagues valiantly swimming against the tide, I'm afraid I can't in good conscience advise any non-US citizen to take up a PhD or postdoc in the US right now. Mind you, all the ECRs I've given guidance to lately needed no persuading on this point.

Hundreds of staff leave Edinburgh University amid cuts drive According to the university, 345 of these departures were the result of a targeted voluntary severance (VS) scheme run by the institution in 2025.

Missing from the coverage of redundancies at Edinburgh: this was done in such a haphazard, uncoordinated way, there are now core teams who have gone from 5 people to 1 with no change in workload or pressure and huge loss in knowledge of institutional process. www.heraldscotland.com/news/2576321...
