Students at #SNOLAB are starting to engage in our common orientation for research experiences. One particle that comes up really early is the #muon. Students often don't learn about subatomic particle properties other than #electrons, #protons, and #neutrons until late in university. I made this video explicitly to help early-career students get familiar with the muon and see how it was the first direct test of the #relativity of time:

It was great to welcome to SNOLAB a new winter class of #students and share with them pieces of the #SNOLAB science portfolio. I loved the questions afterward about #neutrino mass measurement!
Very pleased to be in #Ottawa this week to support conversations with the laboratory's funding partners in the Federal Government, and to participate in the 2025 Canadian Science Policy Conference.
I am very grateful to be able to share #SNOLAB's science mission and learn from others about the evolving science policy landscape.
Pleased to be part of the #SNOLAB team at the Xenon Workshop in #Montreal. Many great discussions with a recognition that cooperation across projects is important to advancing this technology.

If you are curious about #SNOLAB, its scientific program, and the outcome of the recent effort to develop a 15-year plan for the laboratory, check out my virtual seminar tomorrow. It is hosted by the Institute for Underground Science.
Nov. 12, 2025
9am MT/11am ET
Register for the zoom link (see quoted post below)
These talks are recorded for later viewing.
I am very excited about my "Deeper Talk" seminar hosted by the Institute for Underground Science at #SURF. If you would be interested in learning more about the @snolabscience.bsky.social science program and the recently developed 15-year vision for the laboratory, register for the webinar!
Had fun curling today with colleagues and friends from #SNOLAB.
A team at #SNOLAB is getting ready to conduct a program of research and development on the #electroforming of metals for science-grade applications. We have learned a lot from the researchers and labs who have made great strides in this before us and we are excited to step in and see what frontiers we can explore or define in this space.
But first, we start simple and small! This was a test assembly using ultra-pure water as we assess readiness for first operations soon.
Want to learn more about why we do science deep underground? Check out my keynote lecture from the 2025 Stellafane Convention, “Astronomy Without Light”:

You can check out the interview with Dr. CK Jung, public lecture speaker on the physics of sports at #Sudbury’s Refettorio open-air theatre on October 1, in this recording from today’s “Morning North” program on #CBC Radio One Sudbury!

There is very little else that is more satisfying than a busy electronics crate in an experimental data acquisition system.

SNOLAB is more than a global leader for underground science and discovery; we are Ontario’s training ground for scientists, technologists, and tradespeople … talent made right here in Ontario. #SNOLAB #MadeinOntario #OntarioResearch #TradesMatters #Innovation #HigherEducation
It was an honour to be able to support the tour for Minister Quinn and MPP Rosenberg at #SNOLAB this past week. I am especially proud of the work that scientific staff, as well as students and post-docs working on their experiments, did to share the human stories of underground science and the wonder of their discovery quest.

@snolabscience.bsky.social is stronger when the public and its representatives can engage in this journey.
Good things are happening on our underground 3D printer at #SNOLAB! I am very excited for the next phase of the student-led cloud chamber project, as we take this design to the next level.
I am sad that I cannot partake in #monsterdon tonight … I have to get up early to go work in the underground lab at #SNOLAB. I wish everyone partaking in the community movie watch a good view. I snuck a peak at “Frankenstein Meets the Space Monster” and it’s … um … it’s.
KILLER soundtrack though. :-)
Had an EXCELLENT time volunteering with @jodi and many other staff from @snolabscience.bsky.social at the #SNOLAB tent at #ScienceNorth today. Engaging with the public about the lab and sharing the joy of making things (buttons!) was a great way to spend #CanadaDay.
Shout out to our amazing #Education and #Outreach team for organizing this today!
(Rethread of post)
#SNOLAB’s monitoring station is CAN7023 and on a typical day sees a gamma radiation level of about 50-70 nanoSieverts per hour (nSv/h). Typical ambient radiation levels are 2 mSv in a year. Gamma radiation would thus typically contribute 0.5 mSv in a year, or about 1/4 of the total amount. Many gamma rays come from cosmic radiation acting on the atmosphere.
You nuclear-curious folks might watch for changes in public gamma levels in the coming days.
There is also a growing body of evidence that, at a minimum, some microorganisms suffer negative health consequences when DEPRIVED of ambient (background) radiation. Since life evolved in an ambient radiation environment, this would be evidence that too LITTLE radiation can have negative health consequences. There may be a “goldilocks” radiation zone for Earth life.
