New work describes our efforts to achieve CRISPR editing of the mitochondrial genome. www.biorxiv.org/lookup/conte...

I'm thrilled to share our work from @weissmanlab.bsky.social (www.sciencedirect.com/science/arti...). We developed LOCL-TL, an optogenetic approach for monitoring localized translation in mammalian cells. LOCL-TL revealed two distinct strategies for mitochondrially localized translation.

Proximity-specific ribosome profiling using LOV-BirA reveals two distinct strategies for mitochondrially-localized translation: one for long coding sequences and one for short. It was a pleasure to contribute to this beautiful work from Jonathan Weissman @weissmanlab.bsky.social‬ and Jingchuan Luo

A new paper from @aliceyting.bsky.social reports on LaccID, an engineered laccase, that enables hydrogen peroxide-free proximity labeling and electron microscopy of cell surfaces www.nature.com/articles/s41...

Can a single researcher test over half a million chemical reactions in <3 days? Yes, using Jeff Martell’s new DNA-encoded combinatorial screening platform. Check out his lab’s exciting new preprint 👇

We are hiring a new lab manager! Our wonderful lab manager Albert is headed off to grad school and we are looking to fill his position this summer. This is a great opportunity for a new graduate to spend a couple years immersed in research before applying to PhD or MD programs. 50% of the job is...

Today we report the directed evolution of HUH into rHUH, a sequence-specific covalent protein tag for RNA labeling. rHUH was hard to engineer: the initial HUH template had no RNA activity, so we started with RNA-DNA hybrids. 30 rounds of selection on the yeast surface were required, and 7 cycles of

Tetanus on demand! (not for bioweapons, but for neuroscience research) Tetanus toxin induces paralysis by using a protease to cleave VAMP2, a protein required for synaptic vesicle fusion and neurotransmitter release. To harness this toxicity and use it as a beneficial tool for neuroscience,

Are you a Japanese student interested in a postdoctoral fellowship in the US? The Chan Zuckerberg Initiative has an exciting new fully-funded Global Science Scholars program to pair students who have received their undergraduate or doctoral degrees in Japan with US bioengineering and biomedical...

Could one envision a synthetic receptor technology that is fully programmable, able to detect diverse extracellular antigens – both soluble and cell-attached – and convert that recognition into a wide range of intracellular responses, from gene expression and real-time fluorescence to modulation..
