We’re pleased to welcome Linn Evans to the South Dakota Science and Technology Authority (SDSTA) Board of Directors. Appointed by Gov. Larry Rhoden, Evans brings deep leadership and underground mining experience to support SDSTA’s mission at SURF. Welcome, Linn!

SURF's at #APSSummit26 this week! If you’re attending the American Physical Society Global Physics Summit in Denver, stop by and see the SURF team at Booth #1728. Learn more about the science happening at America’s Underground Lab.

ICYMI: The February 2026 edition of SURF’s Deeper Talks series covered the low-background counting infrastructure of the Black Hills State University Underground Campus (BHUC). See the recording: vimeo.com/1163999784?sha…

Save the date! #NeutrinoDay returns July 11, 2026 — a city-wide science festival in Lead hosted by the Sanford Underground Research Facility.

Today is International Day of Women and Girls in Science. We recognize the women and girls whose curiosity, persistence, and work continue to advance world-class science and inspire learning across generations. #womeninscience #WomenInSTEM #UndergroundScience

This shot, taken by @sdsmt physics Ph.D. candidate Abbi Elger, shows the view down the pre-analyzing-magnet section of the CASPAR beamline. Submit a photo for photo of the week to communications@sanfordlab.org.

Congratulations to the 2026 SURF Artist in Residence, Rachel Berg! We look forward to welcoming Berg back to Lead, SD, this summer and seeing America's Underground Lab through her artistic eye. Learn more about Rachel at sanfordlab.org/news/rachel-be…

Neutrinos and optics may seem worlds apart—but quantum physics connects them. Earlier this month, Dr. Joseph Formaggio explored neutrino oscillations, coherence, and the possibility of superradiance in neutrino physics. Watch the recording here: sanfordlab.us12.list-manage.com/track/click?u=…

Why go underground? At Earth’s surface, cosmic rays constantly bombard us, creating background “noise” for #physics experiments. Nearly a mile underground at SURF’s 4,850 Level, rock naturally shields detectors—reducing cosmic rays by a factor of 10 million. #undergroundscience

At our next Deeper Talks, Dr. Joseph Formaggio explores the surprising connections between optics and neutrino physics—from quantum coherence to the speculative idea of superradiant neutrino emission. Register at the link below! events.zoom.us/ev/AptvpHDVhc5…

#ICYMI SURF is proud to support advances in geothermal energy! Our underground environment enables experiments exploring new ways to harness Earth’s heat—research that could help meet future global energy needs. 🔗 renewableenergymagazine.com/geothermal/an-…

Did you know that @DUNEScience is the largest neutrino experiment ever undertaken? With excavation finished, 2025 work centered on outfitting the underground research space with essential infrastructure such as power and utilities. @LBNFacility @SanfordLab

❄️ Season’s Greetings from Sanford Underground Research Facility ❄️ Wishing everyone Happy Holidays, a Merry Christmas, and a Happy New Year!

Mentorship in motion at SURF. Early-career researchers learning side by side with senior scientists through CETUP*. Conversations like these shape careers and fuel discovery. #CETUP #Mentorship #Science

SURF’s at #AGU25! If you’re attending the @theAGU Fall Meeting this week, stop by booth #824 and learn how SURF supports cutting-edge research a mile underground. Pictured: Jaret Heise, Director of Science, and Markus Horn, Senior Research Scientist. #AGU #UndergroundScience

At our next Deeper Talks, Dr. James Bowen of @UnivOfKansas will discuss how the Compact Muon Solenoid Experiment at @CERN measured dijets in photon-nuclear collisions. Join us Wednesday, December 10 at 9 a.m. MT by registering for free below. events.zoom.us/ev/AglGynjHObr…

The LZ #DarkMatter experiment has set a world’s best in the hunt for galactic dark matter – and gotten a new look at #neutrinos from the sun’s core. #physics Read more: sanfordlab.org/news/lz-sets-w…
