How do mosquitoes find people to bite & places to lay eggs? Turns out, sensing water vapor is key. In new work we (Tang et al.) ID mosquito receptors for dry/moist air. KO'ing them drops blood feeding and renders females unable to find water to lay eggs. pnas.org/doi/10.1073/pnas.24…
Ava Towle '26 studies how fruit flies sense temperature through G-Protein Coupled Receptors in the Shapiro Science Center lab, highlighting some of the exciting research on campus this summer. #Research#Brandeis

My autobiography is now published on the @NobelPrize website. It covers both my personal and professional life, highlighting the decisions and events that have had the biggest impact. I appreciate the opportunity to tell my story. Hope you enjoy reading it

Sad news: John DeModena, long-time tech w/@wormraiserand friend to so many of us, has passed. Demo’s generosity of spirit and enthusiasm for life were inspiring. There will be a celebration of Demo’s life 1/27 in the Morgan library
Preprint: Structure of an insect gustatory receptor. Heather Frank, Sanket Walujkar, Richard Walsh, Willem Laursen, Doug Theobald, me and Rachelle Gaudet. Collaborative effort 5 years in the making! biorxiv.org/content/10.1101/… 1/4
Take homes: Unlike known ORs, Gr9’s ligand-binding pocket is larger, solvent accessible and heavy on polar/aromatics. Using structure-based alignments and alphaFold, we leverage this to examine structural and chemical properties of GRs more broadly. 3/4
For GR fans: Signature motif residues (TYhhhhhQF) make specific contributions to pore helix: T helps form hydrophilic path; Y binds lipid head group; QF gates pore entrance. Also new: intersubunit fenestrations of both GRs and ORs are inhabited by pore-penetrating lipids. 4/4
We are back to business! The very first in vivo voltage imaging in Huang lab. Look at how this neuron changes firing mode. This simplistic voltage scope only costs ~$50k, mostly @Thorlabs parts. Let me know if you want a full part-list to build your own one.
University Professor Eve Marder ’69 & Professor Emeritus Gregory Petsko have each received the National Medal of Science from President Biden, the highest recognition the nation bestows on scientists & engineers.
