Inferring bird migration from bone isotopes and histology: A fossil‐friendly methodological framework Bird seasonal migration is a remarkable biogeographic phenomenon, yet its deep-time origin(s) and evolutionary history remain poorly understood, with the bird fossil record largely overlooked. Thi...

New paper out today! "Fossil otolith assemblages reveal millennial-scale changes in reef fish biomass and trophic structure across the Isthmus of Panama"

🔓https://doi.org/10.1098/rstb.2024.0419

We used fossil fish otoliths to reconstruct community structure and energetics over millennia.

Our scientists have unravelled a 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today.

BREAKING Irish Govt to move Grok to another parish.

Professor John Marshall, in outdoor attire, operates a power drill on a rocky, barren mountainside. He wears a dark hat, glasses, and has a gray beard. The terrain is steep with loose dirt and stones.

Two people in bright orange survival suits and life jackets are on a small inflatable boat. They are navigating icy waters, with icebergs visible in the background and a cloudy sky overhead. One person is handling the motor, while the other sits facing forward.

Red and black tents are pitched on a snowy, rocky slope under an overcast sky. The ground is thinly covered with snow, revealing many stones. The background shows a large, snow-dusted hill.

Professor John Marshal with glasses and a hat smiles at the camera while sitting beside a rocky outcrop. He is wearing a beige vest and blue sleeves. In front of him are geological tools including a hammer, measuring tape, and a notepad with notes.

Congratulations to Professor John Marshall on his Polar Medal, recognising his decades of research in the harsh polar regions.

Awarded by His Majesty King Charles III to those who have made outstanding achievements in polar research.

Sunny part of Sussex in summer. Green rolling hills with a strong lazing about and doing nothing vibe, possibly with cricket on the radio and ants in a sandwich nearby.

I think I had a good science idea this weekend. I’m hoping if I ignore it, it’ll go away and I can try relaxing.

I have one! Bought in the late 80s when I grew up and part ex for a NJ BC Rich... Lovely guitar, bloody heavy though.

Buy a parcel and help give mums and their children in our refuges their first Christmas of freedom. When a child arrives at a refuge in the countdown to Christmas, they’re withdrawn and in shock.

Christmas, innit. How about we get some things for women and children with nothing who are escaping domestic violence? You can do that, as ever, via the brilliant Refuge. Check this out: donate.refuge.org.uk/page/180196/...
