New paper in @CurrentBiology by @aninditabrahma_, @Dom_Frank3, Daniel Hejazi Pastor, and @patKpiekarski @RockefellerUniv. We discovered that ants use a wild “new” mechanism to regulate gene expression at large tandem arrays of odorant receptors (1/7): authors.elsevier.com/sd/article/S09…
Ants have expanded repertoires of odorant receptors compared to other insects, and most of these genes are arranged in large genomic tandem arrays. This poses a challenge: how does an olfactory sensory neuron express a single receptor from an array? (2/7)

Scout-initiated group raiding in ants is an incredibly rich collective behavior that can now be studied in the lab. Exciting new @biorxivpreprint from our lab @RockefellerUniv with @VChandra_ & @asafffgal biorxiv.org/content/10.110…. (1/8) Scout-initiated group raids are stereotyped in the sequence of events, but there is interesting variation in the length of some phases. Lots of cool collective decision making and navigation as well. @biorxiv_evobio @biorxiv_neursci @biorxiv_ecology. biorxiv.org/content/10.110… (2/8)
