The conversation around biomedical research is often louder than the data. Most Americans support responsible, regulated biomedical research with animals. Explore the full results and methodology, then use your voice to support the future of life-saving science at ONPRC. savescienceoregon.org/poll

New polling shows what Americans really think about biomedical research with animals. Explore the results.

Despite the attention given to activist campaigns, a recent survey of more than 2,000 U.S. adults found that 62% support biomedical animal research when veterinarians oversee animal welfare. These facts deserve a place in the conversation about ONPRC's future. savescienceoregon.org/poll

The unprecedented move would have ended hundreds of studies at one of the largest academic monkey centers in the United States. But on Thursday, OHSU President Shereef Elnahal told faculty leaders the plan could not move forward because of a lack of federal funding. My latest for @science.org

Plan to turn major monkey research facility into sanctuary may be dead
Lack of federal funds may have forced Oregon university to drop idea of converting national primate center into science-free refuge

Critics say the proposal was made without consulting experts, does not specify how the transfer or lifetime care of the animals would be funded, and could endanger the monkeys if they’re not carefully integrated into their new home. My latest for @science.org

I spoke with CNN about why scientists like me are leaving the U.S. 🇺🇸: Your research in virology and #LongCovid is not relevant, and we no longer need you. 🇩🇪 🇬🇧 🇵🇹 🇨🇦: Come work with us, we want you. Read behind the paywall here: dale-confirmation-1.ezihost.net #BrainDrain #SpeakOut
For a couple of months, Beckman said she considered stepping away from her Covid-19 research, which has become increasingly politicized under the Trump administration.

But then she started getting interviews at institutions in other countries.

“There is interest in virology everywhere in the world except the US right now.”
