Got someone in my family with diabetes type I, and we've been hearing about the "magical" solution coming "soon" since she was diagnosed with it, in her childhood, around 30 years ago.
As such I'll keep what I see as a healthy amount of scepticism towards this piece of news.
Another from chemistry: "small dangers are still dangers, don't underestimate them".
This was in my first uni. The person saying that mentioned how he never saw students harming themselves with cyanide, nitration solutions (sulphuric+nitric - highly corrosive and explosive) or the likes. No, it was always with dumb shit like glacial acetic acid skin burns, or a solvent catching fire.
