🇧🇷🇺🇸Evolutionary Cell Mechanobiology of Archaea. Assistant Professor at Brandeis University.
Waltham-MA
Joined November 2009
This story started 5y ago with my lab. Spearheaded by fearless 1st authors @theopi and Olivia Leland. Theopi is now a PhD student at @BrownUniversity. Olivia is a physics PhD student at @BrandeisU, a self-taught biologist, and made us love soft matter. A (very long) thread (1/24)

It is exciting to see how biophysics, cell biology, and systems biology are co-evolving as a field. Tech allows fast orthogonal data collection across conditions, moving away from "genetic pathway <-> function" and phenotypes alone can connect genes/proteins to mechanism (4/4)

Changed the biochemistry (pH, salt, substrate...)? Mechanics (osmolarity, electrical/magnetic field...)? Developmental program? Yeah, you are likely changing all the other outputs and shifting "bottlenecks". That's part of the "noisy" natural selection process (3/4)

Cell wall synthesis? Turgor fluctuations (periplasm and cytoplasm)? Membrane tension? Assembly of the cytokinetic ring? FtsZ treadmilling itself? The answer is: it does not matter because these are moving pieces, and physiological conditions are coupled with cell mechanics (2/4)

This is one of my fav bac cell div papers. It's remarkable how much we've learned about cytokinesis in the past decade, and how much we still don't know. This paper harmonizes many of the disagreements in the field, like what limits construction rates (1/4)
I’m happy to note one of my favorite papers from the lab on cell division just came online, where by modulating and measuring membrane tension we find that 1) bundling of FtsZ filaments works against the membrane tension to bend the membrane inward.

Alright fellas. Come one come all, #amateurbiology poster presentation at #asmicrobe on our first set of methylation screening results on Halococcus. Come ask about an exciting new finding I couldn't put on the poster! #archaea EEB 1147 @kmaclea @Archaeon_Alex

What it has become a classic review every ~5 years by the Polschroder (UPenn) and Schulze (RIT) labs, showing how the improvements in the techniques used in Mol and Cell Bio model Haloferax volcanii , the "E. coli" of the Archaea.
Haloferax volcanii stands out as a model archaeon. Discover how it is catalyzing development of new technologies & databases that facilitate discovery-driven research, with implications for biotechnology, biomedicine & biological questions. #JBacteriology: https://t.co/hCo9si02uh

Apart of the sad week, I want to celebrate my quick but inspiring trip to UIUC, home of Archaea. I was gifted the nicest thing I ever owned: a set square that belonged to Ralph Wolfe, pioneer of methanogenic Archaea TY, Abigail Finn and Chemical Biology Fellows. You're +++

Making a heatmap is an essential skill for a bioinformatician. But you probably do not understand heatmap. 7 reading resources to understand heatmap! 🧵

Is the genome just a bag of genes? A new paper in @ScienceMagazine now reports that for two thirds of an organisms' genes the position along the chromosome is actually very tightly constrained! Amazing work from my favorite night scientist @MartinJLercher and his team!

Super excited our paper on circRNA stability in the brain and their use as life experience markers is out! @inespatop @kadenerlab
cell.com
Kirio et al. demonstrate that circRNAs steadily accumulate in the aging fly brain due to their exceptional stability. Temperature exposure (29°C) further elevates select circRNAs, which remain high...

@ItaiYanai Milton Glaser, the graphic designer makes the point that personal development is inherently antithetical to professional success, an exemplar being Picasso, who was extraordinary because he regularly abandoned his accomplishments. https://t.co/NA7eplH2zg

Expert’s dilemma: An increase in a scientist’s abilities for creative interdisciplinary thinking is almost inevitably linked to a loss in expertise and thus credibility in their home field, reducing the acceptability of the work to their peers https://t.co/uLCo9bhCmA

Tissue-like multicellular development triggered by mechanical compression in archaea @Archaeon_Alex @BrandeisLS | Science
science.org
The advent of clonal multicellularity is a critical evolutionary milestone, seen often in eukaryotes, rarely in bacteria, and only once in archaea. We show that uniaxial compression induces clonal...
