I downvoted because high-impact activities are known to build bone density. I honestly don't know what causes one person to get injured and not another, but I don't think it's the "impact" of running, which is what

I tend to agree with "where there's smoke, there's fire," but I'm also cautious reading too much into what a single person -- in particular, an ex-lover -- has to say when forming an opinion about someone. Obviously

Is there a “me”? I’m unconvinced by “cogito, ergo sum.” Has always felt a bit circular to me.

My experience has been great with mushrooms, just to add another datapoint. I mean, it's often about as good as you can get by eye without breaking out the lab equipment.

I've read that because Parkinson's is caused by the death of dopaminergic neurons in the brain, the same process could be affecting dopaminergic cells in the eye, which do exist. This might be what they're seeing. Thoughts?

A few comments on diamagnetism: The most strongly diamagnetic materials that aren't a superconductor are bismuth and pyrolytic carbon, a graphite-like material. Bismuth has a density of about 10g/cm^3, and a diamagnetic strength (

Honestly a lot are really hard to read. You start with the easy ones, learn the lingo, and then just keep going. Eventually you can enjoy reading the harder ones. You learn pretty quickly that if you want answers, it's better to just g

Thanks for the reply, and great work on making a cool product. It's really impressive, and I hope it does well.

This is the future. I also know that in-advance EOBs* happen to be on the agenda for the CMS. I'm curious about how you solved a couple of problems because it's becoming clearer to me that healthcare operates in a probabilistic wa

Cool thanks. Gonna read up a little on that. Edit: yea it's interesting. Believe it or not, I studied L-G theory in grad school, taught a lab about (type-II) superconductors, but had no idea that type-I superconductors didn't flu

I’m not an expert, but I’ve used superconductors (I believe YBCO) when I taught physics lab. We cooled samples down with liquid nitrogen and put them over a magnet. They levitate, but not like in the video that the Korean team released. Tru

Health insurers have their profits capped by the ACA. They can’t make more than 120% of what they spend. Obviously this creates an incentive to spend more, and that’s a whole other discussion, but the point stands that they aren’t paying ba

We're gotta work with whatever the hospitals give us. The most common codes we see are CPT/HCPCS codes (coupled with revenue codes), or DRG codes. When the hospital provides any one of REV, CPT, HCPCS, MS-DRG, APR-DRG, APC, NDC, o

String theory has been pretty useful outside of string theory proper. There are analogies to lots of other systems which I think continues to breathe life into the research. See: https://www.quantamagazine.org/string-theorys
