President Donald Trump’s administration has terminated $352 million in grants and contracts this year to the Research Triangle Institute, the United States’s third largest independent research organization, a report estimates.

Cuts in global health and climate hit Research Triangle Institute hard

“Financial drubbing” underscores reliance of some independent research organizations on federal funding

So excited to finally share our work on how birds responded to the 2024 Great American Eclipse! Thanks to @rosvall-lab.bsky.social for inviting me on this journey! I never expected any of my research to show up in @science.org, let alone on the cover. Surreal. I hope you enjoy it!

As the Moon eclipsed the Sun on 8 April 2024, birds took note.

Leveraging nature’s own experiment, scientists and the public joined forces to show how different species responded to sudden midafternoon darkness followed by a new “dawn.” Learn more this week in Science: https://scim.ag/48WbhLL

As the Moon eclipsed the Sun on 8 April 2024, birds like these rock pigeons (Columba livia) took note.

Just out in @science.org: Together with the lab of @johanneszuber.bsky.social, we used sequential in-vitro/in-vivo screens to decipher metabolic adaptations in tumors. We find that acidosis is a dominant factor that shapes energy metabolism and stress resilience. www.science.org/doi/10.1126/...

Scientists recently found two evolutionarily distinct mushrooms converged to produce the same psychedelic molecule—psilocybin.

The “surprising” results underscore the significance of the hallucinogen but leave questions about its ultimate purpose.

For behavioral scientists struggling to recruit enough subjects for their studies, #AI offers a tantalizing solution: artificial “participants” that can stand in for real people.

But a new preprint calls for caution before researchers make the leap. https://scim.ag/42myIdg

AI-generated ‘participants’ can lead social science experiments astray, study finds

Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings
