How do tumors or bacteria modulate their environment, and how does that translate into their growth? What can we learn from maths, and what are the implications for cancer therapy or ecosystem resilience? Register here for the first Eco-Onco session, April 22nd forms.gle/B77tZmyzCzmp...

Excited to announce Eco-Onco Exchange — a virtual seminar series bridging mathematical ecology and oncology.
Each session pairs two speakers from each field around a shared theme, followed by joint discussion.
First three sessions coming soon! Register here docs.google.com/forms/d/e/1F...

This seems like a very dangerous place to be holding a trial.

We are looking for a Postdoc to join our lab at @oxfordbiochemistry.bsky.social. This is a dry-lab focused post on the computational analysis of long read single-cell sequencing data to understand the role of transposable elements (TEs) in early development. my.corehr.com/pls/uoxrecru... #TEsky

If you've put in a #MuSpAn code request in the last few days and haven't heard anything, please let me know - looks like there was an issue with our hosting which meant the requests weren't coming through!

I think I've sorted the backlog but please shout if you're still waiting for code access :)

Many thanks to everyone from the MRC National Mouse Genetics Network who participated in our #MuSpAn hackathon in York last week - fantastic to see how much everyone was able to discover in just one week!

A big shout out to the National STEM learning centre and the NMGN for hosting/organising!

(Does this count as "kerning"? It's a good word and feels kind of appropriate even if it's just regular "misalignment", so I'm sticking with it)

Please sign my petition to remove one letter from the word "Middlesbrough" so that the kerning on the BBC Sport app is better.

Does it really need both Ds? Or maybe one of those silent letters near the end could be quietly dropped?

Some of the maths of the model fit on the easter egg page (there's SO MUCH MORE LOL I AM A NERD), including a little linear fit with the CI shown.

Yes, my wedding has a website

Yes, I have also included modelling of the expected temperature on the day

Yes, I did this by fitting a Bayesian model to 45 years of temperature data

Yes, the wedding website has an easter egg with a little link to find a writeup of how I got the numbers

The sun rising over the London skyline this morning, only it’s a very cloudy sky and the sun is visible only as an orange streak of fire that coincidentally seems to be emanating from the spire on the top of St Paul’s dome

Dear All
Have you seen Prof Biscuit recently?

Professor Biscuit is roaming Main Building or more likely, is asleep somewhere cosy. Have you seen him recently? If so, could he be persuaded to be returned to the Bursary, please?

Dear All Have you seen Prof Biscuit recently? Professor Biscuit is roaming Main Building or more likely, is asleep somewhere cosy. Have you seen him recently? If so, could he be persuaded to be returned to the Bursary, please?

They're also responsible for one of the best emails I've ever received, when the college office sent out a plea for sightings of Professor Biscuit while conveniently forgetting to mention that he was a cat...(I won't comment on how often a similar email might have gone out about human Professors...)

I don't remember the exact details of St Hugh's getting AF/PB, but IIRC the rescue centre promoted Biscuit to full Professor when they found he was moving to Oxford, prompting a college wide competition to decide on an appropriate rank for Flapjack.

Oxford Clarion's "Cat map" of Oxford cats

Oxford Clarion's "Cat map" of Oxford cats

I reckon you can learn a lot about the atmosphere in various Oxford colleges by looking at what they choose to name their cats (courtesy of @oxfordclarion.bsky.social ). We should all aspire to the energy of a Teabag, Isambard Kitten Brunel, or an Admiral Flapjack

We just advertised the Hooke Fellowships for exceptional researchers (typically after their first post-doc).

You are completely free to set up your own research agenda for three years.
