Here is a copy of the open letter from the heads of physics departments across the UK- worth reading as it makes a lot of excellent points

📢 @astroroyalscot.bsky.social, Prof. Jon Butterworth, & our rep for Early-Career Researchers, Simon Williams @si-wills.bsky.social will meet the SITC Committee next week to talk about the STFC funding!
Let's all attend the hearing in person and online!🙎💻

STFC CEO responds to @jonbutterworth.bsky.social
"it is important for all of our ... programmes ... to contribute to us making savings across our entire portfolio"
No mention that *all* is disproportionately falling on the particle-astro-nuclear programme 🤷♀️😡

For anyone in London next weekend - get yourself down to this absolutely wonderful combination of art & astronomy. It’s a really special place.
The future of fundamental physics research in the UK is under serious threat because of the massive government cuts to STFC funding. Please read this open letter by advanced fellows.

Very interesting to see this laid out by someone who was, until very recently, on STFC's Science Board.
Listeners to Radio 4’s Inside Science today get an essay from me in defence of astronomy as pure research. Please listen in and let me know what you think.
Show starts 4.30pm GMT here: www.bbc.co.uk/programmes/b...

Another positive is that the community response to the planned cuts 16 years ago actually had an effect. Some extra funding was found at the last minute. So, it is worth speaking out and pointing out these planned cuts will do a lot of damage to very active, and successful, research areas. 4/4
The Royal Astronomical Society is gravely concerned at the drastic cuts to support for UK astronomy outlined by the Science and Technology Facilities Council.

We're so excited to share the results of the ALMA large program ARKS that studied the distribution of dust and gas in a sample of 24 exoKuiper belts. With @lucaroundtheworld.bsky.social, Meredith Hughes and a large collaboration, we just published 10 papers presenting our first results arkslp.org
Well this is worrying. NASA has maintained funding for ADS but not SciX (a broader database). In response, management is planning to *close* ADS in Feb 2026, forcing all users to switch to SciX. ☄️🔭

We can see Io rotate slightly over the hour-long timelapse, tracking volcanoes on its surface!
And check out the Conversation piece for a cool slider showing how NGC 1068 lines up perfectly with previous data from LBTI.
So, the main takeaway: you need to correctly account for dust evolution and ice chemistry when trying to understand complex molecules in planet forming disks!
Unfortunately including this is time consuming and computationally difficult, but ultimately we think this is going to be the only way to reconcile the models with the observations in the future.
So what is this telling us? A big limitation of the modelling here is that it is static, but we know dust grains move radially and vertically in disks and can redistribute molecules when they do so.
The second surprising result is that even after throwing the chemical kitchen sink at the model (honestly, see Table 2) we could *not* reproduce the column density profile of methanol. We didn't have enough of it (short by ~1-2 orders of magnitude) and it was all in the wrong place (the outer disk).
TW Hya is great because it's so well studied and there is a wealth of information on the disk physical structure. We combined some pretty advanced chemical modelling (thanks to Catherine) with a really well benchmarked model of the disk (thanks to Jenny).
Our first surprising result was than the methanol was cold (~35K) suggesting it wasn't coming from thermal desorption of ices on dust grains, but instead by non-thermal processes. This led us to start looking more into how it could be formed chemically…
We can look at the relative intensities of each of these transitions to pull out physical information like excitation temperature and column density for the methanol gas, and since the observations were spatially resolved, we see how these change radially through the disk.
Methanol is the starting point for lots of important prebiotic chemistry. So far it has only been detected in a disk around one solar-type star, TW Hya. We used #ALMA to go back and get some very sensitive, high-resolution observations of multiple transitions for the first time.
Great to see our paper on methanol in TW Hya finally come out today (with Catherine Walsh and Jenny Calahan). A quick overview.... 🔭 ☄️ #radioastro
arxiv.org/abs/2510.04106
Ultimately, we think including these types of processes is going to be the only way to reconcile the models with the observations. But the main takeaway is that the distribution of important prebiotic molecules in disks is likely highly dependent on treating dust (and ice) evolution correctly!
