Yes, I agree this is vastly over-engineered. There are commercial solar farms that actively point toward the sun, but many (most?) do not, because they may fail. Before medicine, I studied and worked in renewable energy: in medicine, simpli

Physician, anesthesiologist speaking. Intravenous phenylephrine widely used, effective. No good in stomach. Doctors struggle to harness all the historic use and evidence for treatments, sometimes based on great evidence. Often evidence is t

My points all apply, even if I thought it did not warrant pursuing to the full text. I did not state the article was wrong, although I think it is quite likely to be worthless, and therefore not worth my time.

Temporary or permanent disability is also important. As I won't pay Elsevier to read this article, I can't evaluate the (likely) methodolgical failings. Even major journals sometimes let papers with significant methodological flaw

I am an anaesthetia doctor. There is, in fact, only mixed evidence of checklists actually helping in various health systems around the world. At a national level, Scotland began using checklists, but the whole health system and population i

The outcome measure was whether the participants felt good. The authors dangle the _association_ of this with actual longevity, which of course means nothing whatsoever in the context of this very weak study in an irrelevant journal.

The incorrect assumption your readers are making is that heart surgery is a good thing in all cases. America is the leader in futile medical procedures: it may well be a good thing to have fewer risky procedures on patients who were more li

This and many other points are left unaddressed by the authors. They fall at the first hurdle, so I hope this discussion can move on to some of the other interesting things people have mentioned.

They could have gone with: "Sloppy scientists delude themselves about unlikely hypothesis" People repeating the fiction that "low blood sugar puts one in a bad mood" puts people in a bad mood when they haven't had s

A lot of peer reviewed literature is also junk, and occasionally non-peer-reviewed papers are breathtaking. One of my favourite (peer reviewed) articles ever is: http://journals.plos.org/plosmedicine/article?id=10.1371&

Yes, this is another flaw, but there are much bigger flaws in their work! Also, they only fasted people for 3h. I've sucked a lot of junk out of peoples' stomachs who have had longer fasts, so this is not even a glycogenolisis pha

People often say this, but I'm not yet convinced it has a fully or even partially physiologic basis. One way to do an experiment would be to fast someone for 48h (about when you completely run out of glycogen, and ketones start to ramp

This is an interesting point. As others addressed the main issues, I would just add that dieting does not need to be continuous exercise of will power. It may just take will power in establishing an environment not surrounded by unhealthy f

This is one of the earliest tricks of the paper. In the initial discussion they cite numerous authors on why low glucose, i.e. hypoglycemia, affects cognition. I have seen many hypoglycemic diabetics in bad trouble from this. However, the a

I agree. And they don't even show there was a decline in their initial experiment on which their entire chain of reasoning is based: control group glucose before: 102+/-21, after 103+/-18 intervention glucose before: 107+&#x

I'm a physician. There are a lot of problems with the original article. The body is excellent at maintaining glucose concentration in the blood with food or with days of fasting. Glucose is the primary short-term energy source for most

Please also remove the unsourced (and untrue) claim about the present, too! I wrote a thesis ten years ago which examined the engineering and economics of a more simple kite/glider pair system. Aerodynamically, it can be stable and sel
