From January 1st 2026, the CNRS will cut access to one of the largest commercial bibliometric databases, Clarivate Analytics' Web of Science, along with the Core Collection and Journal Citation Reports.

If your job now consists of simply regurgitating AI (“I just ask Chat”), anyone can do that.

Be careful, you can and will be replaced. Not by something better, rather by something worse but much cheaper.

The skill, the value, will be in producing something that AI cannot. Practice that.

🌊 Funded PhD: Advancing Plankton Imaging & Machine Learning to Transform Marine Biodiversity Monitoring 🔬🌍 @plymuni.bsky.social
Bring together AI-powered image analysis, innovative sensors, and real-world policy frameworks.

Two funding options:
1. lnkd.in/e566f8RR
2. lnkd.in/eKPRGhsP

Anyone good with marine flagellates? I thought this was quite a distinctive-looking chap with a reasonable chance of an ID? Any ideas?

An illustration showing an aerial view of Vráble, showing three neighborhoods. Walled off: The fortified neighborhood was surrounded by a deep, V-shaped ditch 1 kilometer long, reinforced by an earthen wall and another ditch. While digging trenches to understand the fortifications, researchers found headless bodies buried near one entrance. Ditch burials: Nearly 100 people were placed in the ditch near the wall's southernmost opening or gate, in a layer of bodies extending more than 45 meters along the ditch. The densest concentration of bodies was closest to the gate.

Archaeologists find evidence that a wave of mass brutality accompanied the collapse of the first pan-European culture.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

I served as our Ambassador in Ukraine for 3 years under Putin’s missiles and drones but resigned when Trump kept appeasing Putin. America does not bow to dictators. It’s not who we are.

Here's why this Trump-Putin so-called "peace plan" is a disaster:

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji.

It ships many new features, detailed below, but that are articulated around the following:

Left: Changes in cell density and cell volume when comparing high nutrient condition (base of each arrow) to indicated starvation conditions (tip of each arrow). Gravitational sinking velocities are indicated in color-coded background. Top right: A transmission electron microscopy image of Tetraselmis sp., a green alga, reveals the internal organization and composition of the cell, as seen under high-growth conditions. Bottom right: A scanning electron microscopy image of Tetraselmis sp., portraying the sinking of the cell following starvation. Image credits: Teemu P. Miettinen, Margaret Bisher, Abigail K. R. Lytton-Jean.

Marine #phytoplankton need move up/down in the #ocean to access light & nutrients. Study of the effects of nutrient availability in 9 species reveals that phytoplankton have evolved multiple mechanisms that impact gravitational sinking in response to starvation @plosbiology.org 🧪 plos.io/4iaJFoV

How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926
