@romanzug.bsky.social and @socialinsectlab.bsky.social thinking about colony dynamics! Resource variation can mask tradeoffs, but here we show that even if that *doesn't* vary, lucky starts in colony life can lead to better trajectories and if so, a tradeoff is often undetectable despite being real.

Why is it so hard to detect fecundity-longevity #trade-offs in social insects? And what does this have to do with the Gospel of #Matthew??

Luck can explain the positive link between fecundity and longevity: the Matthew effect in social insects and beyond
Abstract. The universality of the trade-off between fecundity and longevity in life-history theory is sometimes contested. Social insects present the argua

In 2016, Jane Goodall spoke at the International Primatological Society meetings. She closed her talk asking everyone to thank the primates we studied not with applause, but with their calls. And so a room full of Very Eminent Primatologists made delighted monkey noises to Jane Goodall. ⚱️🐒🧪🌍

What started as an attempt to compare CT scans of diverse fly brains, ended up a new concept for analysis & segmentation of difficult tomographic data. No ground truths, no training, just maths. This is TopoTome, topological data analysis of 3D images

www.biorxiv.org/content/10.1...
Figure showing 3 panels. Panel A: workflow of a classical deep learning model vs TopoTome workflow, with marked differences between the methods, including manual segmentation of images, design and optimization of neural network and data post processing that is needed in deep learning workflow but not in TopoTome. Panel B: core concepts behind TopoTome shown connected by arrows. From left to right, there is a microCT scan of a fly brain (3D reconstruction), a persistence barcode of H2 homologies, an image of how persistent barcodes map to the original CT brain scan, and a segmentation of a CT scan. Panel C shows the concept of cubical complex filtration of 2D and 3D image data.

Cornell is cancelling a distinguished professor's classes on Gaza and suspending him because of the complaints of a student who previously served in Israel's military surveillance agency and was literally recording the comments of other students in class and deliberately derailing discussion.
Early last semester, Droubi said, students began approaching Cheyfitz with complaints that a graduate student in the “Gaza, Indigeneity, Resistance” class appeared to be recording them, possibly to “gather their names and comments” and intimidate them. “We believe that a student came to the course for the sole reason of surveilling and potentially harming students in the class,” Droubi said. “That ended up proving itself to be true because multiple students came forward and shared their concerns with Professor Cheyfitz.” Cheyfitz said one Palestinian student quit the class after telling him she felt upset and frightened. Current Issue Cover of October 2025 Issue October 2025 Issue According to Cheyfitz, the graduate student often steered conversations away from the assigned readings—which at that point mostly focused on definitions of genocide and international law on Indigenous rights—to defend Israel’s conduct in the war in Gaza and argue with others in the class. “He clearly had not done the readings,” Cheyfitz said. “It was disruptive.” Cheyfitz said he met with the graduate student in late January and spoke to him about concerns from his classmates. During the conversation, he asked the graduate student to drop the course, and by the next class, he did, Cheyfitz said. The graduate student, Oren Renard, a PhD candidate in computer science whose identity was confirmed by other students in the class, previously served in Israel’s elite military surveillance agency, Unit 8200, according to his LinkedIn profile.

Our new study is out in Cell Reports!
We show that the DNA repair pathway ATM-γH2Av is repurposed in the gut during infection, even without DNA breaks. Pathogens, not microbiota, trigger it via NOX to clear damaged cells and drive stem cell regeneration. www.cell.com/cell-reports...
Infectious bacteria, but not the microbiota, induce a NOX-ATM-cytokine pathway that controls epithelial turnover
Nagy et al. identify a NOX-ATM-cytokine signaling axis in the Drosophila gut that is activated by infection independently of DNA damage. This pathway promotes enterocyte loss, cytokine production, and...

AOC: We should be clear about who Charlie Kirk was. A man who believed that the civil rights act that granted black Americans the right to vote was a mistake… His rhetoric and beliefs were ignorant, uneducated, and sought to disenfranchise millions of Americans.

Hello #Drosophila & #insect people!
I am searching for libraries of ORF/RNA from Tribolium castaneum and Bombyx mori for cloning cDNA/proteins (or insects with unusual body plans).
Is there an existing resource centre where I can find them, please?
Thanks very much in advance for your help!

The goal of a PhD is not to learn some facts or read a few papers or learn a bunch of techniques. The goal of a PhD is to learn independence, problem solving, how to finish things you start, resilience, & gain the ability to adapt & think creatively. Learning these things is hard.
