Sadly, their entire business is built on paywalling content the community built and distributed for free.

CSF sampling is a routine investigation in most hospitals. We don't typically see bacteria in these samples, when we do, its in the form of bacterial meningitis, hence the skepticism.

I'm a doctor training in anaesthesia. The idea with epidurals is to introduce local anaesthetic outside the compartment where the spinal cord is, literally epi-- --durally.

To sample the CSF, or to give a spinal anaesthetic, the needle needs to be introduced into the subarachnoid (one of the membranes that surrounds the central nervous system) space, but at a level below where the spinal cord has terminated. This is why they're done in the lower back typically.

Bending over is a totally legitimate way to perform them, and doesn't really alter the complication rate, while making the procedure easier. Also, there isn't really any realistic option to perform them in real time with imaging guidance. The author is right in that larger cutting needles are associated with increased rates of PDPH.

I suppose that's where things like tip jars work quite well. To reward useful but otherwise niche content.

It's very similar in the UK. Most estate agents will use a third party these days, but the amount of information you have to hand over is ridiculous.

Just making a dumb joke that if it's the pathologist that's the person removing an appendix, they're probably dead already.

Totally does work, lots of spacecraft use reaction wheels to control attitude.

There are lots of ways things don't work. The plumbing can be connected up wrong or the pumps can not work.

He's a pathologist, so if he has removed someone's appendix they'd probably be dead. Pedantry aside, your point still stands.

Interesting, I saw the same!

I'm pretty sure there are academics who would bite their own legs off for tax records from this period.

Does this matter to them though? Does apple care about having the dominant messaging platform if it's no longer a hook to get people to buy apple devices.

That's so much more readable, even as someone who's read some Illich.

There's unfortunately only so much you can achieve with scalp-based electrodes. The applications everyone dreams about - like fine BCI or controlling robotic arms - are hard to achieve with signals once they've had to pass through the cranium.
