POV: You walk into a physics lab and see someone firing protons...at frog eggs? Welcome to Carnegie in the 1940s, where nuclear physics smashed into biology and sparked a whole new field. #ScienceHistory https://carnegiescience.edu/news/atoms-cells-history-biophysics-section

When a group of nuclear physicists decided to study life instead of atoms, everything changed. Their interdisciplinary leap helped shape the rise of modern molecular biology. Here’s how it happened ↓ https://carnegiescience.edu/news/atoms-cells-history-biophysics-section

We’re excited to announce that astronomer Michael R. Blanton has been named the 12th Director of the Carnegie Science Observatories! He joins us from New York University, where he served as Director of the Center for Cosmology and Particle Physics. (1/5) Full Press Release👇 buff.ly/JZ0J81w

New PNAS study shows that life’s signature lingers in rocks long after the original biomolecules are gone. Hazen, Wong (@miquai.bsky.social) & Prabhu (@anirudhprabhu.bsky.social) found chemical traces of ancient life in 3.3 BYO rocks. Let’s get into it. (1/6) 👉 carnegiescience.edu/chemical-evi...

At Carnegie Science, we study the origin and evolution of everything, says President John Mulchaey. Our expertise builds connections between the origins of "star stuff," the formation of planets, the rise of life, and the search for life elsewhere.

Thank you to the 500+ guests who joined us for a day of discovery at our first-ever #EPLOpenHouse. It was a blast—literally! 🌋 Your curiosity made the day shine, and we can’t wait to do it again next year! Until then, check out our upcoming events: 👉 https://bit.ly/43vMivk

A newly discovered asteroid travels around the Sun in just 128 days—the second-fastest unique asteroid orbit in the Solar System. First observed by Carnegie's Scott Sheppard, the asteroid—called 2025 SC79—was found hiding in the Sun’s glare. carnegiescience.edu/news/fast-mo...

The application portal for the next wave of @carnegiescience.bsky.social postdoctoral fellows is open through November 3. I hope you’ll consider joining us 🚀
