Thanks, @winkie.bsky.social at @usatoday.com for reporting on our analysis of plutonium pit production. Lots to unpack here, so here's a short thread (1/n)

This week, multiple leaders from the Centers for Disease Control and Prevention (CDC) were ousted or resigned due to continued political interference and pressure to limit vaccine access. These firings defy all scientific evidence and endanger our health. We must not allow it to stand.
Union of Concerned Scientists (@ucs.org)
Dylan Spaulding, a nuclear security expert for the Union of Concerned Scientists, argued in a May report that NNSA's two-site approach for pit production is "questionable" and has unnecessarily driven up costs for reasons that are "likely more political than technical."

Hurricane Katrina underscored a reality that has become undeniable in the years since: Climate change together with long-standing racial and socioeconomic inequities are the background conditions within which communities experience extreme disasters. Read more lessons learned from Rachel Cleetus.

Federal scientific integrity (SI) policies were created to protect fed scientists & their work from politicization, retaliation, & censorship. The Trump admin is replacing them w/ new policies to give the admin more leeway in politicizing science to reach conclusions convenient for its agenda🧵
