Well deserved! When I was searching for an example of how a discovery about the brain unlocked an entirely new class of therapies (while writing Elusive Cures), orexin is what I pointed to. It doesn't always happen this way. When it does **it's epic** and we should celebrate.

NIH's Aug 2026 proposal would scrap exact scores and percentiles for three broad bins (top = top 25%). With funding rates at 5% or lower, too much then rides on administrative discretion. It devalues peer review and is a deterrent to engage. Tell NIH before Oct 13. grants.nih.gov/grants/guide...

graphical abstract of the manuscript depicting pink estrogen-sensitive neurons with a subset of their nuclei colored in green. These green nuclei represent estrogen receptor dependent neural gene transcription, tracked via the expression of a destabilized GFP with a 2 hour half-life. At top, in green is shown a cartoon of the neural response to estrogen across two estrous cycles, and below there is a cartoon of a mouse implanted with an optic fiber for in vivo imaging.
