Excited to share our work on ErbB receptors published today @CellCellPress! Using multicolor, photostable UCNPs, we perform long-term (>15 min) single-particle tracking of EGFR, HER2, and HER3, enabling direct visualization of dimerization in live cells. cell.com/cell/fulltext/S0092…

We also identified stable, ligand-independent heterodimers among all three receptors. These insights offer a comprehensive ErbB interaction network, elucidating diverse dimerization mechanisms and implications for oncogenic signaling.

The 2026 Breakthrough Prize ceremony (“the Oscars for science”) celebrated the achievements of many remarkable scientists and their students and collaborators last weekend. Here’s the video of the show: youtu.be/_CZHeEyZBU0?si=blLQ…. And here’s the segment in which Anne Hathaway and Alex Honnold (who climbed El Capitan free solo) presented the story of baby K.J.’s base editing treatment and introduced Kiran Musunuru, Rebecca Ahrens-Nicklas, Peter Marks, baby K.J. and his wonderful family, and myself: youtu.be/_CZHeEyZBU0?si=blLQ…

Happy to share our paper on long-term single-particle tracking in live neurons @nchembio. We showed that the number of active dynein motors can switch stochastically during the long transport, and we resolved the molecular steps of dynein. nature.com/articles/s41589-0…

Excited to share the first paper from the lab! pubs.acs.org/doi/full/10.102… Limited by photobleaching in single-molecule imaging? We present multicolor long-term single-particle tracking in live cells for 10 min. The probes are actually stable for more than several hours!

Thank you @broadinstitute for making this great video to introduce our work!
Meet @CTSPeng, one of Broad's new core members. Hear from Peng as he describes his lab's work developing novel probes and microscopy techniques that enable long-term imaging in living systems. youtube.com/watch?v=zyYx43tB…
