We are happy to finally announce the 1st meeting of our special topic network on synthesizing micro- and macro- evolutionary processes shaping prokaryotic genomes, supported by ESEB. The meeting will be hosted at the Milner Center for Evolution at the University of Bath, UK, from 30 May to 1 June 2022. We have a great... Continue Reading →
Our paper reporting the impact of selection bias in mutation accumulation (MA) experiments is now published! A few years ago, Mrudula had tested the effect of single mutations accumulated in MA experiments (see Sane et al 2018, Evolution), finding that a surprisingly large fraction were beneficial. In the new paper, mathematician Lindi Wahl uses simulations... Continue Reading →
Arun's paper reporting the detailed costs and benefits of evolved immune priming is now published! In an exciting earlier study, we had found that flour beetles exposed to the pathogen Bacillus thuringiensis adapted rapidly via the evolution of either immune priming or pathogen resistance. The new work – led by Arun (now at Edinburgh University)... Continue Reading →
Our work on ‘useful’ mistakes in bacteria (E. coli) is finally out! Laasya and Parth found that making rebel proteins not encoded by our DNA can be a good thing. In cells that frequently make mistakes, the accumulated ‘junk’ proteins end up triggering a high alert situation. This allows the cells to better deal with... Continue Reading →
Bacteria are so small and so ubiquitous that it seems like they should be found everywhere. But recent work shows that much like animals and plants, most bacteria have discrete distributions. We asked: does host association shape bacterial distribution in nature? In Pratibha's first paper from the lab, we describe how bacteria from the genus... Continue Reading →
Rittik Deb and Ashwin Nair's paper on the gut bacterial communities of dragonflies is out! We sampled several species of dragonflies from different locations in India, and found that gut bacterial communities varied across host species, location, and season. For some of the dragonflies, we were also able to analyse gut contents, and found that... Continue Reading →
