My participation in #SciArtSeptember has been a bit sporadic - chronic illness is messing with me. But here is one of my favourite animals, the Tawny Owl. Love to hear them calling to each other 🤎

What do bacterial cells do when they run out of nutrients? Although most bacterial studies focus on cells in exponentially growing states, in the wild bacteria likely spend most of their time slowly starving to death. 1/n

E. coli prepares for starvation by dramatically remodeling its proteome in the first hours after loss of nutrients
It is widely believed that due to nutrient limitations in natural environments, bacteria spend most of their life in non-growing states. However, very little is known about how bacteria change their p...

PLOS Biology about how non-linear careers are increasingly common, but funding agencies and search committees penalize these paths. journals.plos.org/plosbiology/...

New paper alert!

Really excited to see this work from a postdoc with Steve Votier @heriotwattuni.bsky.social published in Ecology & Evolution!
In it, we use existing bio-logging data to study competition and facilitation in foraging gannets.
