Food choices are always a tradeoff between the benefits of energy intake and the risk of accidental contamination. The relative importance of these two varies depending on a person's current metabolic need. (1/3)

Let's share @etlunsford.bsky.social's work : to survive, animals avoid drifting involuntarily in their environment. While humans rely on visual & vestibular cues, birds & fish need to sense complex flow changes of the external fluid (air/water) around them to select motor actions. How do they do?(1)

We are proud to have @maxcapelle.bsky.social's paper out on bioRxiv! He found that phototactic behavior in #zebrafish switches during #ontogeny🐟🔆 Through elegant behavioral dissections, he identifies the navigational strategies related to this transition. www.biorxiv.org/content/10.1... Thread 👇

I’ve been studying gene regulation in primates for over 20 years, and using RNA-seq since 2008 to compare expression across species. We thought we were being careful. We used curated orthologous exons to minimize alignment bias and focused on biologically meaningful comparisons.

We were wrong.

Congrats to @stednitz.bsky.social and Andrew Lesak on their @currentbiology.bsky.social paper! They use HMM to identify two interaction states in #zebrafish: one visual for long-range interactions and one lateral line for quick, close interactions.

Blind mice use stereo olfaction, comparing smells between nostrils, to maintain a stable sense of direction. Blocking this ability disrupts their internal compass.

Starting this summer, and after 11 wonderful years in Munich, the Portugues Lab will be starting a new adventure at the Department of Neurobiology and Behavior (NBB) (nbb.cornell.edu) at Cornell University in Ithaca, NY.

Wow! Congratulations to you and good job Cornell! Can't wait to see all the wonderful things you will come up with there.

New resource, for those finterested!
