LosAlamosNerdon Los Alamos is building a "breath profile" to detect disease non-invasively

Really interesting idea. But breathomics seems tricky — breath signatures can shift with diet, time of day, stress, exercise, even the room you’re in. How do you think a stable baseline could be built across people (or even within one person) without very tight controls? Could this avoid the pitfalls that stalled other non-invasive diagnostics like urine or saliva tests?

LosAlamosNerdon LANL Upgrades Proton Radiography System After 25 Years and 1000 Explosions

Pretty wild to see how the DOE labs certify the stockpile without live testing anymore, just layers of modeling, diagnostics, and some very calculated inference.

Oh, I haven't watched that before.

LosAlamosNerdon LANL's Lansce Accelerator Gets Graphene Armor to Cut Downtime

Is there a material that would be better than graphene at surviving a particle beam?

LosAlamosNerdon Why a 50-year-old particle accelerator keeps failing every 28 days

LANL’s particle accelerator shuts down about every 28 days because a tiny tungsten filament burns out under heat, cesium, and ion bombardment. Researchers are testing graphene coatings—atomic-scale “armor”—to keep it running longer.

I would love to hear if you think this kind of nano-protection could be generalized to other extreme environments (fusion, space, etc).

LosAlamosNerdon Solar Meshtastic BBS on low power dev board [video]

Instructions on how to build an Meshtastic TC2|BBS running on a femtofox board, which requires like power than a Pi. Perfect for solar.

LosAlamosNerdon Create a Vintage BBS on Meshtastic Radio Today

I'm in the process of building a solar powered Meshastic BBS running TC2|BBS on Femtofox/foxbuntu.

I'm surprised the article doesn't mention the Femtofox board.

My use case is emergency preparedness communications, but I'm still pondering the implications of an off grid low bandwith communcations network.

What do you think the future of meshtastic+bbs is?

LosAlamosNerdon From data to diagnosis – how AI is changing the world of medicine

AI isn't just for practitioners and researchers.

You're going to cringe when you hear this, but a week ago I uploaded recent lab results to ChatGPT, and received a thorough reviews of the results. Then I asked if there was a connection between my labs and a medical issue a sibling of mine is having. It clearly outlined how they weren't related and provided prompts for me to ask my doctor as a follow up.

Of course, I should verify everything from CGPT (and I shouldn't share my labs with it), but medicinal AI seems like it could soon be a game changer for patients.
