Have any burning questions on fusion physics — disruptions, runaway electrons, heat exhaust, cranking 1.1 GW of power? CFS's second AMA (ask me anything) on Reddit is 9:30 a.m. ET on Tuesday, June 30, with 4 co-authors of our ARC power plant physics basis papers. These papers lay the foundation for our fusion power plant & help us advance our work in areas like design, engineering, cost reduction: https://www.reddit.com/r/fusion/comments/1uee5po/hi_rfusion_were_the_physicists_behind_the/

Nice new video showing the hoist of our third toroidal field (TF) magnet for our SPARC tokamak — the fusion demonstration machine we're building at CFS HQ in Massachusetts. These electromagnets (each strong enough to lift a small aircraft carrier) will help hold a superhot cloud of charged particles called a plasma. When those particles collide — that's fusion — the process releases tremendous amounts of energy. https://www.youtube.com/shorts/lflVjhWgads

In fusion energy, everything starts with the plasma physics. These five papers lay the foundation for our ARC fusion power plant. 58 authors, 226 pages, and the physics checks out.

Note to fusion skeptics: Sure, it's hard. We get it. In fact, we probably understand the difficulties in way more detail than you do, no offense. But these papers tackle the hardest physics problems head on: disruptions, heat exhaust, plasma stability.

Big news in fusion physics: We've published 5 peer-reviewed papers on the physics basis underpinning our ARC fusion power plant's design. Setting this foundation clears our way for next steps in design and engineering so we can get fusion energy on the grid by the early 2030s.

Details on the papers (58 co-authors, 226 pages, and an accompanying editorial) are here:

Overprovisioning could help help, and better surveillance could be a deterrent, but defending subsea internet cable infrastructure is a hard problem and repairs are slow. https://www.cnn.com/2026/05/31/world/aukus-seabed-cables-defense-intl

I tried YouTube Music for podcasts and can't remember why I ended up with Pocket Casts instead, but it wasn't any of these reasons.

In general I don't like blending music and podcasts, which I use very differently, e.g. pre-downloading and queueing up podcasts. But I'm happy to see Google working on the product.

Any thru hikers out there have recommendations for lightweight solar panels? Ideally with USB-C ports, not USB-A ports, and ideally able to charge a phone directly, not requiring a power bank intermediary?

From Mike Sullivan, Bitwarden's new CEO. There will be changes. (Because of course there will be.)
