To accelerate scientific discovery and support @ENERGY’s Genesis Mission, the @BerkeleyLab-led SYNAPS-I project is using SAM 3 and DINOv3 to automate image segmentation.
By pairing DINOv3’s global semantic context and fine-grained spatial localization with SAM 3’s pixel-level boundary extraction, the researchers are able to compress 3D volume labeling from a month of manual effort to ~15 minutes.

🎉Tomorrow our powerful light source, SSRL, turns 50 years young!
🧬Check out this quick vid on SSRL and Roger Kornberg & team, whose work on molecular biology led to a 2006 Nobel Prize.
Oh, how time flies when you are having fun and doing science.

"It's an opportunity for me to recognise that all the work that so many trainees from my lab have done over the past 25 years and to reflect on how fortunate I have been and share in the celebration with them."
– 2022 chemistry laureate @CarolynBertozzi on her #NobelPrize

Carolyn Bertozzi – awarded the 2022 #NobelPrize in Chemistry – has taken click chemistry to a new dimension and started utilising it in living organisms. Her bioorthogonal reactions take place without disrupting the normal chemistry of the cell.

#tbt 🏁 50 years ago today lab employees ran the length of the 2-mile linear accelerator and back in the first annual SLAC run 🏃 .
🏃♂️Since then 48 races have taken place, the most recent in 2019🏃♀️. #SLACTurns60

New footage captured by Berkeley Lab scientists reveals nanoparticle growth is directed not by difference in size, but by defects! “This is a huge milestone. We are rewriting textbook chemistry, and it’s very exciting!” -Senior Lab Scientist Haimei Zheng newscenter.lbl.gov/2022/07/2…

Congratulations to the 17-2 #beamline @SLAClab @SSRLnews on getting the first light on the #EIGER and a big thanks for sharing the first image 😀
Many more photons (and images) will surely come, so keep an eye on to @Stone_SSRL & @ExistentialChem

Exciting times at @SLAClab and @SSRLnews! Finally putting the first (heavily attenuated) synchrotron X-rays on the @DECTRIS_News Eiger 4M at beamline 17-2. Thanks to @ExistentialChem and Ross Arthur for letting me push the button to take this image.

SLAC researchers have demonstrated that they can use machine learning to optimize the performance of particle accelerators by teaching the algorithms the basic physics principles behind accelerator operations – no prior data needed. stanford.io/2WtSxjC

The #NobelPrize committee couldn't reach Paul Milgrom to share the news that he won, so his fellow winner and neighbor Robert Wilson knocked on his door in the middle of the night.

Our first "rapid access" experiment at #LCLS today! Studying N95 mask materials at the single fiber level. Led by Chris Takacs from @SSRLnews, Alexander Dudchenko from @SLAClab Applied Energy, and Meng Liang from LCLS. Funding from @doescience. What a week!
