New paper! We show that rare earth elements don’t just replace carbonate minerals — they start by growing as highly ordered layers on their surfaces. Fascinating step in understanding REE behavior! Funded @researchireland.ie

How do volcanic rocks lock away CO2? Hydrothermal carbonates in #Svalbard basalts show natural Ca-Mg–Fe trapping of carbon, offering clues for climate tech in basalt-based storage. #ClimateSolutions

Impressive and beautiful solar halo this morning in Dublin. Cirrus clouds containing ice crystals and sunlight refraction and scattering produce this phenomenon. Easier (and safer) to see with sunglasses, of course.

#Glitter’s sparkle hides a darker side – it can change the chemistry of our #oceans
Glitter may seem harmless, but new research shows it could disrupt how marine life builds shells and reefs, posing a hidden threat to ocean ecosystems.
