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...

Does anyone have another source besides BD for the B44 anti-brdu antibody or one that reacts with Idu and limited with Cldu. It’s badly back ordered.
