🧬🌟 Is evolution really random? A new study in Nature challenges the classic theory that DNA mutations are purely random and independent of the environment. The study shows that bacteria can adapt their mutation rates in response to different stresses. #evolution #mutation #bacteria phys.org/news/2024-01-evolutio…

Evolution is not as random as previously thought, finds new study

A new study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease, and climate change.

New species concept just dropped ... no, wait, it actually seems useful. Wayne Maddison & Jeannette Whitton published in @SystBiol's #DiamondOA BSSB so it's free to read and free to authors. Even if the concept itself doesn't take off, I think lots of lectures are going to use the figures and ideas.

The Species as a Reproductive Community Emerging From the Past

Biologists and philosophers of science have been unable to fully resolve the decades-long controversy as to what kind of unit of living biodiversity should receive the valued label “species”: reproductive communities (among sexual organisms), genealo…

Happy to share our latest paper, in which we examined the timing at which different microbial groups colonized the ocean!

The first author (Carolina Martinez) is starting her lab at UC Santa Barbara in 2024 and is looking to recruit postdocs and PhD students, so if this looks interesting to you, please reach out to her!

A timeline of bacterial and archaeal diversification in the ocean

Phylogenomics reveals the timeline over which marine bacteria and archaea colonized the oceans and shows the geological context of their diversification.

Ongoing shuffling of protein fragments diversifies core viral functions linked to interactions with bacterial hosts

Ongoing shuffling of protein fragments diversifies core viral functions linked to interactions with bacterial hosts - Nature Communications

Proteins are composed of distinct functional domains, each serving a specific role. Here, Smug et al. show that phages are able to shuffle fragments of their proteins and this predominantly occurs in proteins involved in bacterial host interactions.

A new episode of the EMBO podcast is out. I spoke with Hsiao-Han Chang, Gytis Dudas, and Hedvig Tamman about viruses, hosts, spillovers, public health... And also starting a new lab, the challenges of mobility, mentorship, and Die Hard Dracula.

"They propose that early protoeukaryotes were predators, relying on bacterial prey. These bacteria, in response to predation, produced toxins as a defense mechanism. Over time, these bacteria were domesticated to serve as mitochondria within eukaryotic cells, and their toxins evolved into apoptotic factors. "

'Both genomes had been analysed before, but the fragmented assemblies had scaffold sizes comparable to the length of long reads prior to assembly. Our new assemblies illustrate how long-read technologies allow for a much better representation of species genomes. We are now able to conduct more accurate downstream assays based on more complete gene and transposable element predictions.'

Revisiting genomes of non-model species with long reads yields new insights into their biology and evolution

High-quality genomes obtained using long-read data allow not only for a better understanding of heterozygosity levels, repeat content, and more accurate gene annotation, and prediction when compared to those obtained with short-read technologies, but…

“several lineages of #amoebae were often recovered from extremely high temperature environments. Studying those lineages may yield great insight into how eukaryotic cells can adapt to life in extremely hot environments.”

Something weird's going on with the Google Scholar index. I just went looking for Janzen (1980) and got ... a paper in Ecological Economics as the top result? And when I forced it to find the canonical paper, it only gave me citations to it?

Did @sse_evolution's move to OUP somehow break the journal's representation in Google Scholar?

Let me have a correct #introduction .
Hi! I’m Djigr, evolutionary #biologist, #paleontologist , #artist and published #paleoartist ! I work on various subjects such as #temnospondyls (#crocofrogs from the past) and 3D molecular structure prediction by AI.
I do #scicom and #sciart on feathered #dinosaurs and #evolution, am known for my fake TV journal #CROW+ that teaches about #crow biology!
I’m a co-founder of Chicken Wings Dinosaurs, which produces cute and cool paleoart :sparkles_fiery:

Happy to say I defended my dissertation "Methods and complexity in phage-bacteria ecology and evolution"!

Much thanks to all those who supported me throughout my PhD.

I'm glad to be sticking around the Turner Lab for another year as a post-doc to continue my work on multispecies phage-bacteria communities
