Ann Wang, who’s on the hunt for dark matter, has been awarded the 2026 Panofsky Fellowship! Wang will help develop a next-generation, ultra-sensitive dark matter detector that could shed light on one of the biggest mysteries in our universe. Learn more: stanford.io/4gEuJi5


Dance of the qubits 👯 Entangled qubits are like 2 dancers moving in perfect harmony, no matter how far apart they are. Just as one dancer spin left reveals the other is spinning right, measuring one entangled qubit instantly shows the state of the other: stanford.io/42gS2Zt
Alchemists once promised to turn straw into gold. In real life, catalysts are amazing at turning one substance into another. Researchers @SLACLab & @BerkeleyLab observed copper acting as a catalyst, which will help scientists improve its performance: www6.slac.stanford.edu/news/2025-04-2…

Happy #NationalAstronomyDay! 🌌 You can manipulate space, time, and #CaptureTheCosmos with us in the NSF-DOE @VRubinObs Orbitviewer app. Start exploring now: orbitviewer.app
Want a chance to see behind-the-scenes at SLAC? Join us at STEM Community Day on October 25 for interactive exhibits, special tours, engaging demos, and fun for all ages! Registration is FREE, but it is limited, so reserve your space now: stanford.io/4mIgWbS

The high-repetition rate of our X-ray pulses allows researchers to observe electrons moving in real time across a molecule, which could pave the way for more efficient light harvesting, impact energy production, drug synthesis, & much more:
In this long-exposure pic taken from Cerro Pachón, cars form a glowing bridge to Cerro Tololo. Cerro Pachón hosts 3 NOIRLab-operated telescopes: 🔭NSF–DOE @VRubinObs, operated jointly with DOE’s @SLAClab 👯Gemini South (1/2 of @GeminiObs) ☄️The 4.1-meter SOAR Telescope

Let’s break it down. 🥤 Plastic waste that is! Ozge Bozkurt uses X-ray light to help design a new way to break down plastics, while also making useful products. Learn how at the #SLACPublicLecture in person or online, October 2 at 7 p.m. PDT: stanford.io/4nA2JyZ

Now we’re cooking… 🧑🍳 Or baking rather. Quantum materials are like the ingredients of a cake - which any good baker knows, need to come together in just the right way to create a phenomenal treat, or in our case quantum phenomena: stanford.io/46PQojW

Rubin Observatory has made the list of @Gizmodo's 2025 Science Fair winners! From building the world's largest digital camera to jointly operating with NSF's NOIRLab, SLAC is helping to #CaptureTheCosmos: stanford.io/47Vu1e4

How it started v. how its going 🖥️ This #FBF shows different control rooms from different decades, 1999 and 2019. How many monitors are too many? The limit does not exist in a SLAC control room!


In control over 5,000 miles away Chile and California aren't exactly close - and @VRubinObs is atop Cerro Pachon at almost 9,000 ft. - but there’s a Rubin control room right here at SLAC! Learn how we use it to help #CaptureTheCosmos: stanford.io/48lOPeK


One is gold, one is nitrogen... both are ultrafast electron diffraction patterns. Best guess which is which? By analyzing changes in patterns like these, scientists learn about motions in materials that take place in less than 100 quadrillionths of a second.

Can you hear me now?📱📶 Imagine getting full bars on Mars. Picking up signals that faint takes extraordinary sensitivity. Quantum sensors, like those used in dark matter experiments, use quantum phenomena to detect extremely subtle signals or changes: stanford.io/4gm6W6k

Antibiotics treat bacterial infections, but bacteria have proven a wily adversary - adapting to resist treatments.🦠 Using our synchrotron, researchers have found a promising new candidate for drug therapies against antibiotic resistant bacteria: stanford.io/4moDmPe

First one to last one 🏗️ In total, 37 cryomodules were delivered from @fermilab and @JLab_News for an upgrade that doubled our LCLS X-ray laser’s electron beam energy in 2023!


The National Laboratory Directors' Council Summit 2025 took place at SLAC this week! Mike Witherall (@LBNL), Thomas Mason (@LosAlamosNatLab), Deborah Gracio & Steven Ashby (@PNNLab), SLAC’s John Sarrao, John Wagner (@INL), Timothy Meyer (@PPPLab), & Jens Dilling (@JLab_News):

How is a superconducting qubit like a gyroscope? 🌐 The slightest disturbance can throw them off. Heat, noise, or material flaws can destroy the qubit’s superposition, forcing it to lose information. Learn "a bit" more: stanford.io/4mV8GpK

"They 'are shared between atoms, and so they basically drive all chemical reactions'," says Ian Gabalski. Learn more about this exciting research here at SLAC: stanford.io/4mSqmSv
A chemical reaction has been put under the microscope as never before using high intensity x-rays. Using this technique individual electrons were tracked during the dissociation of hydrogen from ammonia. chemistryworld.com/news/first-val…
