I'd like to know more about the tumor killing mechanism. The article suggests it's due to the DNA destroying effects of radionucleotides. But these hot grains also produce heat. Many tumors are heat intolerant. Also, cancer cells are hideously good at surviving and rebuilding after genotixic stress. It can actually accelerate acquisition of treatment resistance. Genomes shatter and oncogenes recruit replication machinery amplifying to 10-20s copies in a couple cell divisions.

I used to study nematodes. We routinely used infrared lasers to ablate sub cellular structures like a neuronal axon or dendrite. These multiphoton lasers use 5-6 ultra weak beams and are only destructive where they converge. Which can be a cross section as small as a few nanometers. The worms are transparent and microscopic so you can easily see all their cellular structures under a microscope. Hopefully ML will boost radiography resolution enough we use this kinda of tech on people.
