Dear Colleagues, Making you aware of this revised checklist: βA team of researchers have developed a checklist of 10 critical details each animal study needs to report, such as the number of animals used, their sex, whether they were randomly allocated to a test group and control group, and whether the researchers knew which animal was in which group. βARRIVE 2.0,β published today in seven scientific journals, is a streamlined version of an earlier set of guidelines that were published in 2010.β Learn more: https://www.sciencemag.org/news/2020/07/journals-endorse-new-checklist-clean-sloppy-animal-research?utm_campaign=news_daily_2020-07-14&et_rid=639099181&et_cid=3406666 Susan Meyn Chair, ABRF Committee for Core Rigor and Reproducibility (CCoRRe) https://abrf.org/committee/committee-core-rigor-and-reproducibility-ccorre
