[V3cam] Kīlauea volcano, Hawaii (south Halemaʻumaʻu crater) YouTube video by USGS

Take a break from human folly; watch rocks being born in a fiery red fountain from the very bowels of the earth.

Reaching net zero by 2050 ‘cheaper for UK than one fossil fuel crisis’ Climate change committee finds move to renewable energy would also bring health, economic and security benefits

Achieving the UK’s net zero target by 2050 will cost less than a *single* oil price shock

& will insulate UK against future shocks

Meanwhile Reform UK & Tories want to scrap net zero targets on the grounds of 'cost' - so either foolish or doing donors' bidding

The details in this thread are another deeply undesirable turn in the state of uk academia.

The controversial thing was that there wasn't a tomato base. It was white. Some kind of stinky delicious cheese sauce. Loads of herbs. Oh it was so good. Mini-volcanologists pizza had chips on. 🤯

I feel a strong urge to seek out a decent Italian pizzeria to see if I can eat one this weekend.

I propose the following names for the planned synthetic biological recreations of various extinct superstars:

🦣 The Lammoth (after Colossal CEO Ben Lamm)

🦤 The DoDon’t (de-exctincted Dodo)

🐅 The Trylacine (marks for good effort)

You are welcome.

The Names We Know: The Complexities of Coauthorship and Gender in Archaeology Peer-Reviewed Journals | Advances in Archaeological Practice | Cambridge Core The Names We Know: The Complexities of Coauthorship and Gender in Archaeology Peer-Reviewed Journals - Volume 14 Issue 1

How do we lose the history of women in academia? Well, start by losing their citations to better networked groups…

This makes me think of the citation analyses of ‘who gets taught’ in archaeology that Colleen Morgan at York did (and I tried elsewhere)

Just had a panic that I'd lost my phone while literally holding it scrolling this app.

I think I need a nap.

An photomicroscopic image of rock (syenite). Taken in cross-polarised light, small crystals of dalyite show bright interference colours. Surrounding alkali feldspars appear first order grey.

Photomicrograph of olivine dolerite. Isolated, euhedral to subhedral olivine phenocrysts (showing second and third order interference colours) are surrounded by a groundmass made up of opaque iron oxides and an ophitic intergrowth of small, euhedral plagioclase laths surrounded by large clinopyroxene crystals.

Spectacular olivine dolerite from Fair Head, County Antrim in XPL for #ThinSectionThursday. Olivine shows particularly vibrant interference colours while the ophitic intergrowth of twinned plagioclase and clinopyroxene is a textbook quality example. 🧪⚒️🌋

Compare and contrast the funding call in Kristy's post below with the EPSRC EDI action plan: "2.15. Ensure no short deadlines to funding opportunities. Thoughtful deadlines to enable a greater diversity of people to apply."

Just getting through demand management and being chosen as the institution bid in a fair and transparent process would take longer than this window.

I do love a ghost gable like this found near Ancoats in Manchester - but it's rarer still to find the intangible signs of the puff of smoke from the chimney...

America was winning the race to find Martian life. Then China jumped in. The Mars Sample Return mission got off to a promising start, hunting for potentially humanity-changing space rocks. How did it fall off the rails?

Is there life on Mars? For decades, America was in pole position to find out with its multi-mission Mars Sample Return program.

But MSR is now officially dead. And in the race to find alien life on Mars, it’s now China’s to lose.

In case you’re just waking up, the U.S. has teamed up with Israel overnight to start an illegal war of regime change, apparently on a presidential whim with no involvement of Congress, and they are already committing horrific atrocities.

A very tall lava fountain with tiny dots (people) near the base. The image is a bit forced perspective and we are not as close as it looks

Someone captured my colleagues an I servicing the cameras during Kīlauea’s episode 42. We stopped to discuss what we were seeing, but because I talk with my hands it looks like I’m fixing to push someone in…

Why even bother existing anymore if this is your choice? If you don't want to learn, don't want to create, don't want to engage, don't want to think... what are you even doing here?

Assessing Volcanic Hazards and Financial Exposure: A Closer Look at Insurance Industry Preparedness

This episode has the most movingly hopeful Nuance Window, probably my favourite of all the You're Dead To Me episodes.

A pensive reflection by @moudhy.bsky.social on what we can take from the Epic of Gilgamesh for today's world and our societies challenges.

We found NZ was awesome for playgrounds. And loads under cover so great even in the sun. Unlike Portugal and Malta where you risk 3rd degree burns in the slide.
