Poetry publication: my collaborative crown of sonnets is on sale in News from Nowhere! Organized by Jay Farley and First Take, with support from Open Eye Gallery in Liverpool. The associated film is here: vimeo.com/firsttake/nq... Themes include neuroqueerness as a source of ecological intuition

Ecologist friends! Can anyone recommend papers that link species abundance distributions to ecological processes? I'm interested in what inferences can be made from SADs, and the theoretical basis for those inferences. Thanks 🫶

Microbial Evolution: Impacts on Human Health

Call for Papers

A defining characteristic of infectious diseases is that they evolve. The consequences of this evolution are among the most pressing medical issues facing humanity, including emerging pandemics, antibiotic resistance, and the success or failure of vaccines. Pathogen evolution profoundly influences virulence, transmission, and responses to a broad array of human interventions. While the evolutionary dynamics of pathogens have historically been challenging to study, large-scale genomic sequencing, novel computational tools, and experimental methods are rapidly changing the field. We encourage submissions on the broad topic of the evolution of infectious diseases.

This Special Issue aims to feature research that blends evolutionary approaches to understanding pathogen heterogeneity and ongoing genetic change in clinical samples and models of human infection. It also seeks to highlight opportunities to design treatment and prevention strategies that remain effective in the face of ongoing pathogen evolution.

Submission – open until January 31, 2027

Guest editors
Robert Woods, MD PhD, University of Michigan
Camilo Barbosa, PhD, University of Michigan 
Silvie Huijben, PhD, Arizona State University

Do plasmids evolve faster 🐇, slower 🐢, or just like chromosomes 🧬? In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments! 👇 Check out all the details in Paula’s thread! Hint: 🐇 (most of the time)

Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate
Plasmids are autonomously replicating DNA molecules that stably coexist with chromosomes in bacterial cells. These genetic elements drive horizontal gene transfer and play a fundamental role in bacter...

This work is finally published! 🥳🧬 Plasmids are associated with very variable fitness costs in their different bacterial hosts. But, what is the contribution of each of the plasmid-genes in these host-specific effects? Study led by @jorgesastred.bsky.social, @sanmillan.bsky.social and myself! 1/14

It seems Tesla is detecting vehicles that may have problems, and artificially running their odometers faster so the warranty expires before they have to do any service Just incredible grift
"Tesla Inc. employs an odometer system that utilizes predictive algorithms, energy consumption metrics, and driver behavior multipliers that manipulate and misrepresent the actual mileage travelled by Tesla vehicles," reads the lawsuit. "In so doing, Defendants can, and do, accelerate the rate of depreciation of the value of Tesla vehicles and also the
expiration of Tesla vehicle warranties to reduce or avoid responsibility for contractually required repairs as well as increase the purchase of its extended warranty policy."

Can anyone recommend papers where authors look at pairwise interactions between bacteria within a community context? i.e. interaction strength between strain A and strain B when co-cultured with several/many other strains. Thanks!
