Go check out @jacejostles.bsky.social 's very pretty poster this evening about the science behind guppy magic and science communication. Spot I1 #evol2025

Organizer/Organisateur: Andrea Paz (@andreapaz.bsky.social), Juan Carvajal-Quintero (@juancarvq.bsky.social), Tim Parker, Timothee Poisot (@ctrlalttim.com), Diane Srivastava (@srivastavalab.bsky.social), Cristian Alexander Cruz Rodriguez & Bruno Soares (@bruno-soares.bsky.social)

Lead by my friend @gabrielmoulatlet.bsky.social and with the artistic contribution of our very own Roberto Ruiz (IG: @rob_rz), following the tradition of classic AmNat papers 🫶

Thanks to our other friends and colleagues Wesley Dáttilo and Daniel Kissling for the collab

NASA’s Curiosity rover has uncovered a hidden chemical archive of ancient Mars’ atmosphere, which suggests that large amounts of carbon dioxide have been locked into the planet’s crust, according to a new Science study.

A team of scientists made headlines last night with claims that they had found the “strongest hints yet of biological activity outside the Solar System”. They have met floods of scepticism.

PhD project alert! 🚨 I'm recruiting a PhD student to join my lab and the MacroSize network to investigate the trends, patterns, and processes driving intraspecific variation in fish body size in the Anthropocene. Exciting opportunity to explore ecological dynamics in a changing world! :) 🌎🐟🐠🐡

Cool paper showing how deforestation impacts freshwater fish communities and a nice example on connectivity between blue-green biodiversity!

Small-scale fisheries account for 40% of global catch, providing 20% of micronutrient intakes for up to 2.3 billion people and livelihoods for 1 in 12 people.

Huge effort involving @fao.org & 800 experts, out now in @nature.com

A study of 632 freshwater fish species from 9,989 locations finds climate warming affects fish abundances, with increases at the poleward edges of species’ distributions and declines at the equatorward edges of species’ distributions. In PNAS: www.pnas.org/doi/10.1073/...

Wild #river news—a global survey looking at 3 million rivers over the past 35 years shows the annual flow of water dropped in 44% of the world’s largest downstream rivers while many headwater streams grew. The impact on everything from sediment to irrigation are vast

6th day of Fishmas already! Here's a beautiful but unflatteringly named candy cane fish: the Warteye stargazer (Gillellus uranidea). These tiny fellas get up to about 4cm (on a good day) and carry their eggs tucked behind their pectoral fin – yup, you heard that right: they're armpit brooders... 🤏🐠🧪

It’s interesting that the emojis show the earth from three angles 🌎 🌍 🌏 but not the fourth.

Though 🔵 is a fair approximation of what it would look like.

People underestimate the Pacific.

First, we've discovered the conventional fossil record. Then there was a time for trace fossils. And now even more exotic records reveal the ancient life:
Coprolites, cololites and regurgitalites point to the roots of dinosaur supremacy
