Years with an HN recommendation, 2007–2026

HN recommends it as a dramatic, moving demonstration of what deep brain stimulation can do for tremors.

Andrew, diagnosed with early onset Parkinson's at 35, shows how deep brain stimulation surgery has controlled his motor symptoms. The short video shows his tremors with the stimulator off and on.

“You should see this video to really understand how impressive dbs technology is.” (HN, 2014)

Anyone who wants to see the dramatic impact of deep brain stimulation needs to see this video[1]. Just by turning off and on his neurostimulator (see starting 2:00-ish) see the dramatic change in his body. [1] [this video]

on HN thread Tremor-cancelling spoon for Parkinson's tremors
Obviously something like brain surgery shouldn't be taken lightly, but I've had a family friend with tremors go through the process and the result is pretty amazing. Went from pretty severe tremors to appearing basically completely cured. This is a pretty good example: [this video]
Good example of tremors nearly cured by DBS

Science has a lot going wrong with it. Here are some I can list: P-values, the h-index (article discusses), the funding crunches and (US specific) the cyclic nature of NIH funding, the massively skewed incentives of publish or perish, the entire idea of trying to assign value to discoveries (article discusses), the 2-body problem of family life and science (at least the Germans expect you to have no life and are clear on that), the work-life non-balance, the relatively very poor pay, the hyper-competition and sabotage (in some fields, labs, or universities), the total ignorance of doctors/politicians that take your work and apply it in appalling ways, the entire racket of scientific publishing, etc. As always, we should point out to newcomers to this discussion of one of the most read scientific paper EVER by John P. Ioannidis "Why Most Published Research Findings Are False" [0]. If you don't have access and don't want to use Sci-Hub or ICanHazPDF, here is a youtube of John discussing his work [1]. You can use the google to really jump into a rabbit hole here. Essentially, flip a coin, heads the paper is right, tails the paper is wrong, it really is that bad these days. Ok, so lets just scrap the whole thing then, right? Here is why not: [link] [link] [link] [link] [this video] (a good showing of why science is right and helps folks) [link] So, yeah, science is a mess right now. But if we scientists don't step up and make it not a mess, those scummy money-grubbing scammer dirtbags
