When you look at this Christopher Brough map from their paper on defective concrete you can clearly see that Inishowen & Letterkenny is at the epicenter. It's no wonder Ali Farren & Cllr Joy Beard both affected by this crisis have been elected. Full paper👇sciencedirect.com/science/articl…

Struck by the challenge of this task. A lot of the details within this article are taken from our 2023 paper - even since then the scale and complexity has only increased, and new high risk concrete types are emerging. independent.ie/irish-news/hom…

Rare opportunity to see the last Cornwall refinery of Cornish tin today - a small local operation looking to create a unique product from salvaged tin ore - the temperature was something else!

Useful thread on how the science has progressed in the last 12 months - every publication has pointed overwhelmingly in one direction. #pyrrhotite, #pyrite, #isa

Understandably our train was cancelled and we had to divert round to Plymouth - in the weather chaos we did end up catching Schrodinger's train - it was both cancelled and running at the same time! - (see pic - it did get us home in the end though, for which thank you GWR)

After 7.5 years in the House, I did not get to speak, on behalf of all those who've written, for even 3 minutes, on one of the most important and contested Private Members' Bills we've had... Proof that this is NOT the way for us to legislate on these matters #AssistedDyingBill

Such a difficult day for parliamentarians and the country. This summary from Danny Kruger is on point. Once we establish a 'right to die' everyone facing death will have to choose. The vulnerable will be coerced, subliminally or explicitly.

This is very interesting. Cultural reasons were different obviously but can have an older maternal age with high fertility rates. Raising fertility rates is something the West will need to grapple with in the not far distant future of course - interesting to see how it does.

Coming back to #Irish petrography - sometimes you see Fe oxide staining in hand specimen but rarely such a good example in thin section - this happens when Fe from the oxidising pyrrhotite in the phyllite leaches into the surrounding binder. And it's not just Fe.

Intriguing one from general petrography analysis with what looks like a xenolith of a rounded basalt hosted within another basalt. Both are compositionally very similar suggesting eruption, solidification, erosion & then eruption again. #thinsectionthursday #petrography

A bit of petrographic "tinsel" as we are winding into the Christmas break. This is rare red acicular dumortierite growing within a quartz vein. The vein X-cuts the section so as to leave the dumortierite like a piece of tinsel draped across the sample #geoart #thinsectionthursday
