- EduardTheryq - why would they go with this name when everyone in the field knows about the Therac-25 radiation overexposure incidents?
- slibhb> Currently, the most plausible theory emerging from her team’s research points to metabolism: Healthy and cancerous cells may process reactive oxygen species—unstable oxygen-containing molecules generated during radiation—in very different ways.Reminds me of this which I (think) was linked here a while ago: https://www.nature.com/articles/s12276-020-0384-2It really does feel like all these piecemeal cancer treatments are converging on something resembling a cure.
- owenthejumperThe major issue isn't the speed of delivery, and the cancer.The key question is how do you spare normal tissue, and how do you prove the normal tissue is spared in the long term. Current answer is: You break it apart into multiple sessions, the anti-thesis of FLASH.Source: my wife is a radiation oncologist.
- scytheHey, FLASH finally hit Hacker News! I remember my professors talking about this in graduate school. It's a fairly well-established effect: the tumor selectivity of radiation is much better at ultra-high dose rates. It is still unclear exactly why. But there are a lot of studies about it:https://www.nature.com/articles/s41571-022-00697-z
- ameliusWhat is the intensity at the focal point versus areas surrounding it?
- mv4Does this have to do with cell division?
- bitwizeSounds a little too close, in both name and concept, to Therac for my comfort.

- tiderpengerI generally don't trust cancer-communication if it's juiced up like this incredible headline. There has been huge amounts of progress. We don't need silicon valley idiots starting to make proclamations. It's doing fine without your mediocrity.
