A tiny fossil fish (less than 3cm long) from the 436-million-year-old Chongqing Fish Bed represents the earliest articulated remains of any bony fish in the fossil record, and informs our understanding on the origins of all bony fishes today.🧪👇

December 2025 through February 2026 was the 2nd warmest winter on record for the Contiguous U.S. according to Prism climate data. The widespread record to near record warmth in the west easily outweighed the cool temps in the east. 🔥🔥🔥

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇

PhD candidate in Equine Intestinal Microbiome and Resistome Join this PhD project to study how the equine gut microbiome and resistome can improve gastrointestinal health and combat antimicrobial resistance.

Our faculty has a particularly interesting PhD position open on antimicrobial resistance, effects of antibiotics treatment on the microbiome and resistome, restoration of the equine microbiome using FMT.

Cleaner wrasse show self awareness in stunning mirror experiments Cleaner wrasse have revealed a remarkable new side of fish intelligence. Marked with fake parasites, they used mirrors to inspect and remove the spots—far faster than seen in earlier tests. Even more…

Two panel comic. Panel 1: a museum display of a megalodon jaw fossil, with some museum goers standing around it. There is a graphic on the information tablet next to the fossil, depicting the approximation of the megalodon’s full size compared to a human. Panel 2: “3.6 million years ago:” we see the true megalodon as it existed, a small shark with ludicrously large, juicy lips.

Degradation of fish food webs in the Anthropocene The decrease in body size driven by the selective species turnover is widely altering fish food web topology and function.

New paper out examining fish food web degradation in the Anthropocene. We show the structure of aquatic food webs are changing-- even when species richness doesn’t. These signals are strongly associated with decreases in body size within fish communities. www.science.org/doi/10.1126/... 🌐🐠🐡🦈🐟

These 3-yr drops are stunning. Absolutely stunning.

New Orleans: -55%
Baltimore: -60%
Philly: -60%
Chicago: -40%
Buffalo: -55%
Pittsburgh: -50%
Albuquerque: -40%
Newark: -40%
San Antonio: -55%
Portland: -45%

The media coverage of these staggering drops, tho, is staggering in its relative silence.

just need everyone to know that this is how wildlife biologists in China introduce panda cubs to the wild

Lol too much washing and cleaning, no thanks

BREAKING: The Department of Education has ended its directive that attempted to restrict diversity, equity, and inclusion efforts in schools nationwide.

This is a victory for academic freedom and education equity.

Fossil isotope evidence for trophic simplification on modern Caribbean reefs - Nature Using nitrogen isotopes from ancient and modern fish otoliths and corals, the study shows Caribbean reef food webs are now 60–70% shorter and functionally less diverse, indicating human-driven trophic simplification and increased risk of collapse.

The food chains on modern Caribbean coral reefs may have shortened by up to 70% compared with those on their prehistoric counterparts, according to research in Nature. The findings suggest that modern reefs could be increasingly vulnerable to external stressors and ecosystem collapse. 🌍 🧪

This is a dinoflagellate called Noctiluca scintillans, also known as ‘sea sparkle’. When it appears in large numbers (a bloom) they can bioluminescence when disturbed, making the sea flash blue! This is something I’ve unfortunately never seen, but it’s on my wish list! 1/2 #marineplankton 🦑

Many parasitic plants produce tiny seeds as light as dust: you can barely even see them. But zoom in with a powerful enough microscope, and suddenly they reveal a hidden trove of jewels.
