Viscoelasticity and interface properties of multi-component condensates govern protein sequestration and suppression of amyloid formation Stress granules (SGs) are multi-component protein–RNA condensates widely viewed as crucibles for fibril formation in neurodegenerative diseases such as amyotrophic lateral sclerosis. Here, we test thi...

What physical principles actually govern whether stress granules promote or suppress amyloid formation?

Made with Biorender! Crazy!

Thank you for the quick reply. So the condensate might be more reduced than the surrounding environment due to lower O₂ availability?

We are excited to share our new preprint which is now available to read on biorXiv: doi.org/10.64898/202... 🎉🎉🎉

How does molecular valency shape condensate assembly and function? We used the CO2-fixing organelle in algae—the pyrenoid—to find out… 🧵

Does targeting enzymes and substrates in a condensate lead to rate enhancement? No. Here, we investigate how the condensate environment can inhibit an enzyme reaction.

Spoiler: Mass-transport limitations. We find a strong correlation between diffusion and reaction rates.

New from us in @pnas.org :
We considered the limits of condensate diversity, and engineered DNA droplets to form 9 distinct, homotypic, coexisting phases. Very hard to do this except with nucleic acids. Probably you can make more than 9. (1/3)

Amazing discovery! So what about #redox chemistry in condensates?

Yeah plants are amazing ! Thanks for sharing :).

Plants monitor the integrity of their barrier by sensing gas diffusion - Nature A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

Plants can sense when their barrier is injured—and repair it! 🌱
This stunning work, led by Hiroyuki Iida, shows that wounding is sensed through the diffusion of two gases: ethylene and oxygen.
I had the pleasure of contributing and see this project grow.

This is worth reading! A beautiful testimony of remembering why we chose to do science in the first place: curiosity and excitement, not pressure to publish and secure grants. Even if the research system always tells us otherwise!

Not something you see in textbooks very often: tripolar mitosis.
