    Expensive by UK standards, but cheap vs Bay Area: Cambridge UK. I've not been anywhere else that has the density of interesting people doing interesting stuff. London is not far if…

    generally = sometimes it is less expensive. I guess it wasn't clear, but my point was that healthcare is on average much more expensive in the US.

    "In the US food is generally cheaper than it is in Europe, medical care generally more expensive." I'm not sure when medical care is cheaper in the US. Within the VA system, maybe?…

    I did my PhD in a lab with a few people do 3d printing of organ scaffolds. Many (all?) of them used gelatin over collagen - I think the main factor was cost being much lower. There…

    Its great that the NFL is supporting biomechanics research (and will hopefully help the sport as well). However, while the models are open source they seem to be created for LS-DYN…

    I don't think it's 100% of either of these (outcome vs tech used). If its true research, the outcome isn't known. There are major benefits in developing technology for it's own sak…

    To be truely useful as a diagnostic in major decision-making, it needs to be 90-95%+ accurate. But unfortunately there isn't anything close to this yet. High blood pressure, for ex…

    There is an interesting additional link between cardiovascular disease and bones: calcification (calcium deposits in arteries) also seem to have some link with heart attacks and st…

    Agreed that multiple stents and multiple vessels can be stented in one cath session. My point was more that there isn't very strong evidence or criteria for what constitutes a vess…

    People in a clinical trial typically don't pay for the treatment (or placebo).

    Stents are an incredible piece of engineering, but probably are over-used (particularly in the USA). There are a few issues at play: -Chest pain -Artery narrowing -Heart attack ris…

    Agreed. A large amount of time also goes into things like making figures, which is mostly time-consuming grunt work. I think the key is differentiating between creative work (which…

    In some ways 25 years is an ideal amount of time - means that key patents recently expired. A similar factor lead to the explosion of consumer 3D printers about 5 years ago.

    I learned mostly from MATLAB documentation. Good if you want theory and implementation, and most capabilities can be done with open source equivalents if you don't have MATLAB. htt…

    I think you've amplified an out-of-context statement to try and start an argument, and in fact part of my point is that the main responsibility would go to the teacher. But I would…

    This would be a pretty big step - right now there is a big incentive to be first to publish. Often the researchers who would be doing the replication are competitors, who are racin…
