Here's today's column on the astonishing, ongoing mistreatment of people with #ME/CFS. Please spread it far and wide: the only thing which can break the media's wall of indifference is seeing an article about the issue go viral. Thank you. 1/2 www.theguardian.com/commentisfre...

Abandoned, dismissed and gaslighted: there is no excuse for the way ME sufferers have been betrayed | George Monbiot
Changes in guidance and science seem to have little impact on millions of devastated lives. It’s a social crisis playing out behind closed doors, says Guardian columnist George Monbiot

Portable fold-up scrunch disco ball, ready for eclipse-watching. 10 mm mirror tape, 4 x 15 squares, cut in 1-2 squares from the sides, held with soft iron wire, fixed with duct tape. Unfold, scrunch, put in the sun and shine the blobs on a nice wall. #discoball #eclipse #diskokula #solförmörkelse

Looks to me like the radiant is above the horizon seen from Zaragoza, for example, and from Iceland it will definitely be. So maybe? @saevarhb.bsky.social ?

So the next step is to make sure everyone the path of the 2026, 2027 and 2028 eclipses over here in Europe (and beyond) knows what to do. Which is where you come in, maybe? Hashtag #discoball #boladediscoteca #bouleafacettes #spiegelkugel #discokula etc 🪩☀️🔭 #astro #astronomy

In Rapson et al in (2025), now in the IAU's CAP Journal capjournal.org/articles/310... we were able to show that yes, disco balls really are a GREAT complement to the usual solar eclipse viewing tools. No downside.

This time we wanted to know - does it really work in practice? Do people get it? Do they have fun? Valerie put together a survey and we collected experiences from the 2024 eclipse. And those results made the third paper.

My colleague Alex (then in Stockholm) got it immediately, and suggested we write a paper. We gathered friends (and relatives), did some experiments and numbers, and "Why every observatory needs a disco ball" came out in Physics Education in early 2024: doi.org/10.1088/1361...

Excellent piece from @astrokiwi.bsky.social @sundogplanets.mastodon.social.ap.brid.gy & Laura Revell. This one sentence is the crux of it all 👇 "There is no public mandate for a single company in one country to make changes on that scale to the planet’s atmosphere." Highly recommended. 🔭🧪

A new space race could turn our atmosphere into a ‘crematorium for satellites’
Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

The new #ASPIRES3 Physics report is difficult reading. Physics: * remains male-dominated (24% fem) & privileged * aspirations decline from the start to end of school 😔 * is considered the least interesting, most difficult science 😭 * is for brainy "geeks" 😮‍💨 Lots of useful recommendations though🎢🧪👩‍🔬⚛️

Science diplomacy is needed more now than at any time in history, given the scale of challenges the world faces. Research is often described as a form of ‘soft power’ diplomacy… The first step towards protecting science diplomacy must be to protect science itself. 🧪 www.nature.com/articles/d41...

Science diplomacy can help to heal global rifts — if research is respected
The universal language of science allows nations to reach a mutual understanding of shared problems. But that requires politicians not to meddle in how science is done.
