World Animal Day, marked every October 4th, tends to get framed as an ethics conversation. In preclinical research, it is also a study-design conversation, because welfare and data quality are not two separate arguments. They are the same one. The Scientific Case for Welfare Investment Stressed animals produce noisier data. Elevated stress hormones, disrupted feeding, and general distress introduce physiological variability that shows up as unexplained scatter in a dose-respo

FDA's shift away from mandatory animal testing has been building for a few years, but it moved from principle to practice fast in the past twelve months. For a CRO built around nonhuman primate models, that is not a headline to talk around. It is worth being specific about what has actually changed, what is still pending, and where NHP models still do something the alternatives cannot. What's Actually Changed, With Dates The legal foundation was set by the FDA Modernization A

Not every assay question needs a bigger instrument. It needs a more sensitive one. That is the case we make for luminescence-based detection, and it is why the Tecan Spark Multimode Plate Reader has become one of the more heavily used platforms in our assay development work. Why Luminescence Over Fluorescence Luminescence assays couple a luciferase enzyme with a compatible luciferin substrate to generate light, with no external excitation source required. That absence of exci

ANEWCRO will be at the American College of Toxicology's 47th Annual Meeting, November 15 to 18, 2026, at the JW Marriott Hill Country in San Antonio, Texas. If your program touches nonclinical safety assessment, we would like to compare notes while we are there. What We Are Watching This Year Toxicology's center of gravity keeps shifting: New Approach Methodologies are earning a real seat at the table for specific molecule classes, sponsors are asking harder questions about m

Every September 1st, International Primate Day puts a spotlight on how nonhuman primates are treated in research, conservation, and the wildlife trade. For a nonclinical CRO, that spotlight is worth stepping into rather than avoiding, because the real welfare story in preclinical research is not a talking point competitors skip. It is a sourcing decision made years before a single study begins. The Part of the Story That Gets Missed Public conversation about primates in resea

Why Mauritian-origin cynomolgus macaques offer genetic consistency, low pathogen burden, and predictive PK/PD data for preclinical drug studies.
