TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque: "This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".
Bronze plaque saying "A Letter to the Future. Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it.  August 2019. 415ppm CO2"

🧵 To mark 80 years of discovery, we invited the public to join us in a celebratory project – Cosmic Threads – a community quilt inspired by Jodrell Bank’s rich legacy. Now, we’re delighted to share the results with you in a brand-new exhibition: ow.ly/lv6N50XCNyM

A Cornell-led team said this month that it has created the first “color key” of microorganisms that live in Earth’s clouds. The idea? If similar color signatures show up in an exoplanet’s clouds, it could be a clue that something alive is hiding there. Read more: buff.ly/O1SFwyM 📸 Pixabay/EarthSky.

It’s #supermoon time! If you have clear skies tonight (not likely in NW England…!) do have a look. Your brain is not good at measuring the size and brightness of things on the sky, so you might not be able to tell, but a full moon is always nice to look at! 🌕 Spoke to BBC 5 Live about it at 6.55am.

If comets are like cats, and planetary scientists have been studying domestic cats, tigers, leopards, jaguars, etc., of our solar system for many years, then comet 3I/ATLAS barges in like a serval or ocelot on an unbound e=6 orbit from somewhere else 😂. But it still purrs and scratches #3IATLAS

So today I celebrate the work of @carersinstemm.bsky.social who are calling for systemic changes to funding, policy & culture to support carers in STEM. Funders & employers must listen if they recognise and value the importance of a diverse workforce.👩‍🔬🧪 Read their report 👉 carersinstemm.co.uk 8/9🧵
A Carers Guide for Institutions
1
Ensure institutional expense policy allows for the reimbursement of care-related costs including dependant and co-carer travel expenses.
2
Update and align institutional financial reimbursement policy with funder T&C’s relating to care-giving costs.
3
Establish institutional policy and disseminate to line managers and expense approvers to avoid inconsistent implementation and support.
4
Provide flexible carers grants for all staff and students with minimal administrative burden to flexibly support ad-hoc care and do not mandate online attendance.
5
Consider the competing demands of meeting sustainability goals and the requirement to support carers (e.g. trains, flight times on weekends).
6
Decouple measures of research impact and esteem from travel opportunities with updated academic guidance.
7
Allow for family-friendly travel accommodation options including booking outside of approved institutional travel providers.
8
Provide a per-diem (a daily allowance) option for complex trips to reduce
administrative burden on carers.
9
When hosting an event, ensure risk assessments and insurance policy align to allow access to those under the age of 18.

Equity in science is a beautiful lie — and I’m done pretending
Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system.
