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.

LLOMe has long been used to study lysosomal damage, yet how it works has remained a mystery.
Using cryo-electron tomography, we show it forms amyloid structures inside lysosomes that mechanically rupture membranes – revealing a new paradigm for lysosomal failure.

I am beyond thrilled (like the screaming and jumping type of thrilled) that my SNSF Starting Grant was funded. I will start my own lab @unibe.ch next year, studying succulent anatomy development and if and how this anatomy is required for efficient CAM photosynthesis in different Kalanchoë species 🌱

I am fascinated by how viruses evolve - and not just since #SARSCoV2 has shown us at the global stage how consequential virus evolution can be for us.
In my new story in @science.org I got to explore how researchers are probing deeper into the past with old RNA virus genome.
So a 🧪 thread…

Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.
