Lipids

A primer.

Interesting, and slightly dismaying. If true, the HDL/LDL ratio isn’t really important; all that really matters is the absolute LDL level. Still, a high ratio and reduction of total would reduce LDL. But the most important takeaway from a dietary standpoint is that you are not what you eat — there is little correlation between cholesterol intake and serum cholesterol. A failure to understand this over the decades has resulted in a lot of terrible dietary advice, including the kind that probably killed my father in the seventies.

OWS

In honor of their latest vileness, @SooperMexican has started a new hash tag: #HonestOWSchants

Plus, he’s hijacked another one: #NoNATO

So here’s my question. How does this differ from the usual Marxist/anarchist violent asininity that generally accompanies G-whatevernumber or NATO summits? It’s the same moronic thugs, and nothing new. Well, except for the fact that Nancy Pelosi, Harry Reid, and top Democrats endorsed them.

Diagnosing Falcon

Well, as I expected, that didn’t take long:

Engine pressure anomaly traced to turbopump valve. Replacing on engine 5 and verifying no common mode. #DragonLaunch

So it’s a good thing it shut down — it could have resulted in a catastrophic engine failure in flight, something that SpaceX has theoretically designed for (they claim to have engine-out capability from liftoff, and sufficient inter-engine blast shielding to prevent fratricide), but probably doesn’t want to test, at least this early in the program. Also, they had no performance margin on this mission, so it probably would have meant an abort to a low orbit, and perhaps an inability to get to the ISS.
