I spent 2 months researching/planning/writing my ERC StG application back in 2009, and 2 months again for my ERC CG in 2014. It was necessary to carve out that time to deeply think about why/what/how. I am so pained that so many postdocs are now farming that crucial learning experience off to AI. 😔

🎢 We are seeing a record 7710 proposals – a 60.4% increase since 2026 – for ERC Starting Grants in 2027. ⚛️ Physical Sciences & Engineering proposals are most numerous (43%), followed by Social Sciences & Humanities (29%), and Life Sciences (28%). 🔗 link.europa.eu/d3J8Jw 🧪 #AcademicSky

🔊New gig at super fancy venue alert! #Dundee, Nov 10th, I'll be at The McManus with 🏴󠁧󠁢󠁳󠁣󠁴󠁿artist Gillian Eilidh O'Mara for an in-conversation event about how science, art and storytelling help us explore the Universe and find our place within it. 🔭 🎟️: www.eventbrite.co.uk/e/designing-...

The wonderful & exceptionally talented 🏴󠁧󠁢󠁳󠁣󠁴󠁿artist, Gillian Eilidh O'Mara (insta @light.on.the.sea), has created "this imagined corner of the cosmos" after having her "entire mind blown open" by my book. I'm absolutely blown away: all the love, joy and wonder I poured into the book, in a single picture.

Here's a lovely wee reel the fine folk at #Aberdeen Science Centre put together about my new role as their Patron. Who do you think is having more fun - me or the kids? 😂 #scicomm 👩‍🔬🔭🧪🎢 📹: AV One Solutions

The fine folk at the awesome #Aberdeen Science Centre invited me to become their Patron, with a focus on promoting science and public engagement. I said "when do I start!" 🤗 It's a fantastic day out - do come visit some time! 🏴󠁧󠁢󠁳󠁣󠁴󠁿 #scicomm 🎢🔭 aberdeenbusinessnews.co.uk/astronomer-r...

And Lift Off! A glorious launch of #MMX, the start of an amazingly awesome 5 yr round trip to Mars' moon Phobos. 1yr to get there, 3yrs exploration landing on the surface (twice), then 1yr to get home with the bounty (2tbls of Phobos dust), arriving in the Australian outback in 2031! 🥳🔭🧪🛰️🚀

All eyes on Tanegashima today for the 20:41 (⏰UK) #MMX launch to Mars' moon #Phobos! Getting an idea of scale for 🏴󠁧󠁢󠁳󠁣󠁴󠁿Radio: the spacecraft ≈ the size of a car, Phobos ≈ the size of the Isle of Arran, and the MMX rover ≈ the size of your carry-on suitcase. 🤩 🍿: www.youtube.com/watch?v=Fn6g...

Fab 1st day at #NewScientistLive. Absolutely brilliant astro talks from @chanda.blacksky.app & @chrislintott.bsky.social and I even managed to fangirl Helen Sharman (astronaut) to tell her about the time she visited my school and changed my life. She is the nicest person in the world ever 🤗🔭

As expected, the Prime Minister's promise to sort out the mess of funding for Jodrell actually meant nothing - it seems the government would like it to be some sort of heritage theme park when you can go and see where we used to do science. 🔭

Margot Finn@eicathomefinn.bsky.social

'The University of Manchester is seeking alternative funding sources to keep scientific work at Jodrell Bank going after hearing that lost UK Research and Innovation funding would not be restored despite interventions by the prime minister.'

Extremely loud squeals of excitement chez-Heymans.... that is the actual CERN Director General holding a copy of my book in front of the actual LHC tunnel 🥰 🤩 Huge thanks to @pippawells.bsky.social for taking the book on a little site tour before it joins its friends on the CERN library shelves 🙏⚛️🔭

Pippa Wells@pippawells.bsky.social

@astroroyalscot.bsky.social your fabulous book has made it to the CERN library. We took it to see a plaque commemorating the invention of the WWW by Tim Berners-Lee, and by sheer luck also bumped into CERN Director General, Mark Thomson.

"I have to emphasise how lucky I was. Because when we started this project, everybody realised this was maybe a good idea, but very few thought it would work, including myself." A wonderfully modest quote from Nobel Prize winning Prof Francis Halzen. 🔭 www.bbc.co.uk/news/article...

And finished! This is a really great book that explains the physics so well — easy to understand for all levels. An interesting and fun read. (I lol’ed when the programming chapter started with CH saying she wasn’t old enough to have ever used computer cards … but I am and did 👵 😆)

Dr Lori-Ann Foley@lafoley.bsky.social

Back from holiday and all caught up so I popped How to Design a Universe by @astroroyalscot.bsky.social on to my book stand. I’m 50 pages in after the first reading session. Lovely explanations of the physics, whatever your level. Can’t wait to find out if I live in a simulation. 😀

As arXiv announces a new submission rate limit policy, I refer anyone who is up in arms about it to👇Hogg 2026👇. I'm so confused who would want to submit so much slop? For me (both writing and hiring) it's always been about quality over quantity, every single time. 🧪⚛️ blog.arxiv.org/2026/10/01/u...

Let me recommend grabbing a cup of tea & reading this really thoughtful piece from the inimitable @hogg.bsky.social on moderating AI/LLM use in astrophysics. 🔭 "the real question we face is not ... how we do astrophysics. It is the question of why we do astrophysics." 📖: arxiv.org/pdf/2602.10181

Just heading off to meet P6 of Hillside Primary in Aberdeen this morning. I'll be helping them get ready for tonight's 100hours stargazing challenge. Amazingly the weather Gods appear to be on our side with clear skies forecast up North tonight!🤞🔭 👇Join in with stargazers across the entire globe!

It's been 7 months since I gave evidence at the UKGov select committee hearing, on the policy changes at UKRI which have had a catastrophic impact on funding for UK astronomy and particle physics. When asked if we thought we were the "canary in the coal mine", we said yes..... we weren't wrong. 🧪🔭⚛️

🥳 Alfredo has finished the book & he liked it ☺️ On pitching the idea, most replied "could you write a book about just the things you're the expert on, you know Dark Matter - Lean more into the traditional pop-sci genre?" So glad Bloomsbury allowed me to write and style the book I wanted to read!🙏

Dr Alfredo Carpineti@drcarpineti.bsky.social

A truly great, accessible and fun book from @astroroyalscot.bsky.social - if you have ever wonder if we live in a simulation and want to learn about a lot science, this is the book for you!

One additional 'quick fact': if your name is John, the Nobel committee is twice as likely to award you the Prize for Physics, compared to scientists who are female - Number of physics prizes to a John: 10 - Number of female physics Nobel laureates: 5 Best wishes to all the John-hopefuls this yr 👩‍🔬⚛️

The announcement of the Nobel Prize in Physics is happening in one week – and we'll be breaking the news live at nobelprize.org. Quick facts: - Number of physics prizes: 119 - Individuals awarded the physics prize: 229 - Youngest laureate: 25 - Oldest laureate: 96 - Double physics laureates: 1

I got sent a lump of concrete in the post the other day, with a handwritten message "Is this of interest?" Ha! Take that AI, and your farm of AI-slop! The astronomer royal still gets real mail from lovely people and I'm so delighted they still want to share their mad wonderful weird world with me 🤗

Chris Lintott @chrislintott.bsky.social

I miss getting radical theories of cosmology in mad pamphlets via the post. Now it's all AI-generated email offering me the chance to coauthor the manuscript of the century or - this seems new - insisting I make time to meet with the author to discuss their ideas.
