Cool! Looking over the documentation… what would be a suggestion for how to use this with Vt PET data (where arterial input and metabolite correction are needed due to no valid reference region)? For example TSPO PET.

Similar concerns about NIH leadership. Basic research is under threat, this goes hand in hand with public health. Your constituents need your voice to support science in the USA!

BREAKING: Trump wants to illegally cut off $15 billion in lifesaving NIH research.

Research to cure cancer, Alzheimer's, and so much more is on the line.

These people are LYING about waste, fraud, and abuse at NIH to justify attacking medical research—we all need to say so.

My full statement. ⬇️

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

Biomedical research saves lives.

Great example of how studies involving NHPs are advancing the fight against HIV!

Congratulations to our Picker and Hansen Lab teams and contributors, for the recent publication on neutralizing antibodies and MHC-E-restricted CD8+ T cells. Which have shown the ability to protect against the simian counterpart of HIV.

I wrote a quick-start guide for people to replicate this across the country. It was, in our experience, a very effective way to get real action in a short amount of time.

People are willing to talk to scientists! And when you provide everything, they are happy to contact their reps too. Try it!

Sincere thanks for your steadfast support of biomedical research in this country—it saves lives! Echoing my thanks to @jeff-merkley.bsky.social as well. Do not relent, do not back down. People of the PNW support you both!

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.

#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.”

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.

Speak up now before it is too late.

(inflation adjusted $-s below)
NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

Thanks to the NACC and the judges who appreciated the value of translational NHP research! I am honored to receive this award.

Please fight to protect and ensure the continued federal funding for this important work! Science grants from NIH, NSF, and other orgs (including robust F&A support) must continue. Science is our future!

The result of a large (42 authors!) collaboration:
"Go Figure: Transparency in neuroscience images preserves context and clarifies interpretation"
arxiv.org/abs/2504.07824
TL;DR: The FMRI world can (and should) improve results interpretation and reproducibility *today*, via transparent thresholding.
