Why do we have an article saying basically the same thing every single week here? I get it, and I think everyone here has, exercise is good for you, in many ways, don't sit on your ass all day. I guess it's sad to see this becoming the "Good Morning America" of tech (not that we didn't have those ones already) or the ultra localized we-only-care-about-the-bay-area medium.
The potential context shift I have to offer here is that I perceive that what might be happening is that you see an article saying, "exercise is healthy for you brain!" - and you seem to see that all the time here and are bored of it, and that's reasonable. But what I, as a biologist, see, is an article saying, "The mechanism by which exercise assists the brain is cathepsin B!" That's new to me, I haven't heard it ever before, but I can see how a non-specialist might not be so interested in it -
Which then leads me to the context shift proper: it isn't that the same stuff is coming every single week, it's that you're not specialized enough in this area to understand the critical differences each time it comes across your radar here (and that biology should be having a larger and larger impact isn't surprising - bioinformatics is growing a lot, and health startups are downright ubiquitous - I'm a part of one, myself! :) ).
It's rather like a businessperson who doesn't care to understand the difference between Docker and Virtual Machines - they may justifiably not care when Docker puts out some new feature, but that doesn't mean that the new feature from Docker isn't important. I'm afraid that in a similar manner to the tech news seeping into the businessperson's business news, biology news may be seeping into your tech news, but I think it's justified in both cases.
All that said, you may be totally conversant with the nuances of protein interactions and pathway chemistry, and this same headline may just have escaped me the past few weeks that it has been posted, or something, regardless, I hope I don't offend, it just sounds like/seems like this may be the case- that something outside of your specialty looks like tons of the same old crap, when really it's all critically different, even if the advice arising from it is similar. It's of deep interest to us biotech folks, and we're becoming a larger and larger population on Hacker News, so, there it is. :)
