An innovative gel that forms a layer over teeth and then recruits calcium and phosphate ions from saliva to build new enamel has the potential to change dental treatment. To date, we don't have any way to regenerate the tough outer layer of enamel on our teeth as it erodes with age.
Our medical knowledge is shockingly rudimentary. Why we can’t coax cells to do what they did anyway before is something we really need to understand to pretend to have any kind of medical knowledge. What passes for medicine is nothing more than 19th century++. See this, do that, body will heal. That’s about it. I’m shocked every time I see someone in a wheelchair, how can we have LLMs and hallucinated movies but not understand how a few milligrams of organic matter organizes into nerves? etc etc etc
I am hoping that the absolutely bonkers computing power we are currently wasting on fart videos will be used to simulate matter in the future, here’s to cheering on the AI crash!
We have a pretty good idea how things work during development, it’s tricking those cells into the same process as a fully-formed organism that’s hard. Isolating and distributing the hormones in the right way. I think you’re underselling the complexity and scale of biology. We can’t just put a tiny camera and chemo-sensor inside a neuron and see what’s going on in real time and synthesize up a hundred thousand copies.
