Rain is a startup that fights wildfires. They now have a second version of their system, a large unmanned drone. I was not particularly enthusiastic about that first drone, but their second iteration looks promising. I amended my wildfires post accordingly.

In a previous post I explained the basics of Alzheimer's disease and the current state of the art in our understanding of it. I focused on the amyloid-tau story while hinting at the fact that there are other factors worth exploring. I mentioned the "repeated failures of Alzheimer's drugs in the clinic". This post is about that.
I mostly focused on the Aducanumab case, with solanezumab and lecanemab as contrasts.
These trials have been used as evidence against the amyloid cascade hypothesis (ACH). …
This post, and some that will follow are my attempt to reconcile the repeated failures of Alzheimer's drugs in the clinic with the evidence that the general consensus in the field that the amyloid cascade hypothesis (ACH) is true. Ultimately, what is really causing Alzheimer's, and how might it be stopped? This post will not critically discuss evidence for or against the ACH, rather it will explain what the current accepted definition is, and how it came to be. I know everyone wants to read an analysis of c…

The "what is aging" question is a recurrent one in geroscience (I have my own take here), but everyone would agree that if we take something that we deem old, do something to it, and then we have no way of telling that apart from a younger version of itself, then it's fair to say we have solved aging for that thing.
