there's so much bad in the world but there's also people who lift up and carry an elderly bat around every day so he can pretend he's flying again, and that's the part of the world I think is worth fighting for

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

Can’t believe I’ve never seen this great Collatz conjecture visualisation before…

Judging from the prose, the Pentagon appears to be using AI to announce the death of soldiers. If it’s not AI, it’s a person who simply does not care.

Heating oil prices have more than doubled in the UK since war broke out: that’s 4.5m people living off gas grid, no they haven’t all got Agas, and in places like Cumbria and Scottish islands that’s a lot of anxious pensioners. (Difference with post-Ukraine is oil as well as gas spiking this time)

2/3 So I'm asking the Great British public to help because NF is seeking to be our master.

Were you at school with NF? Worked with him in the City when he was a tin trader? Met him through politics?

1/3 I'm writing a book about Nigel Farage for Headline.

Some of his pals are blanking me.

Is it because after I reported on the killing of a Polish man in Essex in 2016, he said that I had caused him "more misery than any other in 25 years in politics"?

Why are most metabolites barely detectable in wild-type cells — biology or technology?

A new study from the Link lab shows it's biology: cells actively maintain minimal metabolite pools to avoid unwanted effects.

A preview of the MicroSoc2026 pyani-plus hex sticker. It shows a red and blue chequered background (ANI comparison output generated by pyani-plus), over which lies the genomeRxiv logo - two kidney-shaped genomes with base-pairing between them - and white text reading "pyani-plus MicroSoc2026"

We'll be at the

Annual Conference in Belfast this year, with a poster describing the new features in pyani-plus, and a talk about benchmarking genome comparisons. There will also be stickers!

See you there 🦠

Torpedoed by the US. It's a war crime as it's outside combat area. But then it was a war crime when they killed people on boats in the Caribbean.

🧵 UKRI has changed their budgets from considering by disciplines (as bounded by Research Council remits) to by buckets. The inability to see the magnitude of change to disciplinary funding over the spending review period is creating uncertainty.

"we propose that the protoribosome was a parasite (...). If this view is correct, then like the spliceosome in the stem eukaryote, a repurposed host-parasite interaction led to a dramatic change in cell biology at the base of the tree of life, in this case leading to the exit from an RNA world"
