How to engineer a habitable planet: the rise of marine ecosystem engineers through the Phanerozoic doi.org/10.1111/pala... 🧪⚒️🌊 Cribb & Darroch, 2024. "[T]hrough the Phanerozoic, it is clear that bioturbators and reef-building ecosystem engineers have had different trajectories over geological time"

Multicoloured plot showing the relative abundance of different reef-building organisms through time. Vertical axis indicates relative abundance of the different groups, horizontal axis represents time from the Cambrian (over 500 million years ago) on the left to the present day on the right. A white vertical line towards the left of the plot indicates a reef gap that is seen during Stage 10 of the Cambrian Period.
Legend at the bottom indicates the colours used for ten different reef-builder groups (including, among others, different corals, sponges and tube worms). Alt Text from @ThePalAss

Instead of wrestling Big generative AI into submission by cramming even more data down its gullet, maybe just make your own on the cheap? 🧪 source.washu.edu/2024/09/lang...

When it was clear Saturday night, I not only shot the Pleiades (link below), but also five new frames for my Heart Nebula (IC 1805) mosaic. Here is the result. I am glad I finally caught the spur on the lower left. 🔭🧪 1/

Sky full of stars, with whisps of pinkish-reddish gas, including an inverted heart shape in the center and a spur jutting out to the bottom left.

This afternoon in #Argentina's wine country (lee side of Andes rigde) , foehn winds developed lifting large dust clouds. At the same time, Argentina is also covered by smoke from #biomassburning coming down from farther north and some local too.

Did you know that rivers can steal other rivers? It's known as river piracy, and my latest for @cnn.com is about an act of piracy in the Himalayas ~89,000 years ago, with consequences for Mt. Everest

The hed I considered then rejected: A river in the Himalayas fucked around and Everest found out 🧪

River ‘piracy’ gave towering Everest a growth spurt, scientists say | CNN

The Kosi River in the Himalayas once captured part of a tributary: the Arun River. It set off a chain of geological events that reshaped — and is still reshaping — the landscape, a new study has found...

"Countries must work to increase food supplies without converting more natural lands into farms. This will require boosting yields on existing ag land, reducing food loss & waste throughout the supply chain and, in high-income countries, shifting from meat-heavy diets toward more plant-based foods."
