Chronic low-dose exposure to chlorpyrifos reduces life span in a wild fish by accelerating aging Low concentrations of chemicals are widespread in the environment, but exploration of the effects of their chronic exposures on animal life span in the wild is limited. Field investigations showed tha...

(very) Interesting paper showing long-term effects of low-dosage pesticides
Makes you wonder whether other organisms (👀) would show a similar response...

Intracellular competition shapes plasmid population dynamics From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

A mind-reading brain implant that comes with password protection A brain–computer interface decodes in near-real time the imagined speech of people who have difficulty enunciating words.

This is pretty insane, seems like it came out of a fiction book www.nature.com/articles/d41...

Super excited to share our new study, where we introduce and apply a data-driven modeling approach to predict dynamical regimes of ecosystems at unseen environmental conditions (e.g. beyond a tipping point):

This is insane! Evolution is beautiful and “schizogamy” is a great name!
Reproduction mode “in which the posterior body part filled with gametes detaches from the original body, as a reproductive unit (stolon) that autonomously swims and spawns” with eyes!

After a long time away from the former little bird social media, I decided to give it a try here. Back in the good old days, my account was a precious curated scientific bubble that I truly cherished and enjoyed. Hoping to bring these feelings back or keep the nostalgic talk
