Comment Too Fine Grained. (Score 4, Insightful) 635

I think one thing is clear. All these studies are way to focused and fine grained. They look at micro aspects of the climate and then try to apply the observations to a system that is many orders or magnitudes larger.

It's like examining 1" square sections of the Sistine Chapel paintings and then trying to predict the color in the next 1" square based on the color in the current square. Hit and miss, misleading successes and baffling failures because you don't understand the totality of the entire painting.

Being in the midst of trying to control mine, here is a basic explanation provided by my Endocrinologists with some help from Wikipedia.

It all comes down to the Renin–angiotensin system.

When the Kidneys think they don't have enough fluid volume to do their job, they send out signals that ultimately come back to themselves, causing them to retain salt and ditch potassium. Water, naturally, follows the salt and results in increased blood volume and subsequently, pressure. That's why many BP meds contains diuretics.

Too much salts mucks up all the complex feedback mechanisms.

Something that is apparently under diagnosed is a condition called Aldosteronism, where the adrenal glands make too much of a hormone called aldosterone, a primary messenger in this cycle. Aldosterone levels are not part of the standard blood workup done by your average family physician and diagnosing the condition requires a special, hours long process. It's is kind of a Zebra in diagnostic terms but is looking more and more like a horse.

So if you are afflicted with High BP and you're not having much luck controlling it, ask your doctor about aldosterone levels. High BP that is a result of this condition is more dangerous in the long term, but possibly curable by suppressing the aldosterone or removing one of the adrenal glands.

Anyone know the effective resolution and screen size of the Oculus Rift?

Can we envision one day the elimination of external monitors in favor of lightweight and inexpensive versions of Oculus Rift with a form factor closer to that of Google Glass?
