Another Sat Fat Study

No, you don’t increase your saturated fat by eating saturated fat. It’s the carbs, stupid:

The fatty acid called palmitoleic acid, which is associated with “unhealthy metabolism of carbohydrates that can promote disease,” went down with low-carb diets and gradually increased as carbs were re-introduced, the study said.

An increase in this fatty acid indicates that a growing proportion of carbohydrates is being converted into fat instead of being burned by the body, the researchers said.

“When you consume a very low-carb diet your body preferentially burns saturated fat,” Volek said.

“We had people eat two times more saturated fat than they had been eating before entering the study, yet when we measured saturated fat in their blood, it went down in the majority of people,” he said.

The finding “challenges the conventional wisdom that has demonized saturated fat and extends our knowledge of why dietary saturated fat doesn’t correlate with disease,” Volek added.

You don’t say.

Also, how the mindless theory of calorie counting has harmed public health.

Orion

I’m not as excited about this flight as NASA and its booster want me to be, certainly not enough to get up at 4 AM. It just passed apogee, and things seem to be going well.

Meanwhile, PBS (with Miles O’Brien, of course) is the only major network to look at the serious programmatic problems. Lori doesn’t hold back.

[Update a while later, as the post-flight presser is about to start]

The Empire strikes back, briefly, but it won’t last:

The Orion launch has been be a triumph of engineering, hiccups and delays aside. But the Empire may not love the sequel. SpaceX is planning a historic launch of its own next year – the rocket is called the Falcon Heavy. Yes, Musk named his rocket after the Millennium Falcon of Star Wars, and he promises it will take twice as much payload into space as the one Nasa launched on Friday, and at one-third the cost. So far his claims about SpaceX have come true, and soon he’ll be fighting, with the lobbyists and the politicians who play favorites, for satellite contracts worth hundreds of billions of dollars.

Combine that kind of force with Elon Musk’s capsule full of actual people returning to space – under a Nasa contract to deliver astronauts to the International Space Station – and you have a private startup that can beat Nasa or any other government agency back to the moon, if it so chooses.

And so far, it does seem to so choose, though Elon will try to skip the moon and go straight to Mars, unless someone pays him for a lunar mission.

No Sarah Zhang, Orion is not the answer to our space stagnation, it’s a continuation of it.

Putin’s Kremlin And Oil

He’s losing the price war:

Well before Crimea, European nations resented Russian natural gas price gouging. The Kremlin used pricing threats to bully Ukraine, Poland and even Germany into political concessions.

After the Crimean travesty, the Baltic States and Poland demanded alternative gas supplies. The Obama administration quietly agreed to permit U.S. gas exports and the development of a liquefied natural gas exporting facility.

American LNG supplies might reach Poland in three years. That’s good news. Here’s the bad news: Putin has three years to exploit E.U. divisions and politically split NATO.

Or he had three years. Enter Saudi Arabia. America’s “fracking” success challenges Saudi global oil dominance. What’s the price point where fracking becomes unprofitable? Estimates run from $55 to $70 a barrel for oil. The Saudi oil ministry intends to find out and says it will not cut production. The market will determine price.

Though Russia can strangle Ukraine by denying gas supplies, the stunted and corrupt Russian economy survives on energy sales. Without its cash crop of oil, and gas, Russia is a big cabbage farm with a second-rate armaments industry. Cabbage, tanks, ICBMS and nuclear weapons mean Russian is not quite a petro-emirate writ large, but the cruel analogy has instructive utility.

If Russian nukes mean open war with Moscow is too risky, then attacking the Kremlin’s cash generator is war by appropriate means.

The question is, how long will the Saudis be able and/or willing to try to break the US energy industry? Regardless, OPEC is dead. Which is bad news not just for Russia, but Venezuela and Iran. It’s a shame that the administration has been doing almost everything it can to hamstring us.

Orion’s Mission

Paul Spudis deflates a lot of the hype about this week’s flight. The notion that this is a significant part of a Mars architecture is, and always has been, ludicrous.

Sorry, I’ve solved the problem of the missing link.

More from Joel Achenbach:

You don’t need an advanced degree from MIT to grasp that this is a very stately, deliberate program, one free of the sin of haste and the vice of urgency.

Has there ever been a piece of human space hardware developed so slowly?

Or so expensively?

Serious question: Is it not a fact that Orion is the costliest capsule in human history?

Yes, it has lots of bells and whistles that the Apollo capsules lacked. This one has XM/Sirius radio built in, butt-warmers in the seats, four-way adjustable mirrors and Big-Gulp-sized cup-holders. It’s got a guest room, a fully stocked bar, a laundry room and 24-hour concierge service. It’s a really nice spaceship!

…Orion could, in theory, be used for such a mission, but it’s a single piece of what would be a complex array of technologies and hardware. Yes, a journey of a thousand miles starts with a single step, but only if you keep walking, and are seriously committed to the journey — no pretending or arm-waving allowed.

(I drive to the store and buy an onion. I drive home and cut it up and put it in a big pot on the stove and then go watch television. Someone asks me, “What are you doing?” and I answer, “I’m making gumbo.” And the someone says, “What about the garlic, the peppers, the celery, the fresh okra, the andouille sausage, the grilled chicken, the fish, the shrimp, those special blended peppers you always use, and the roux, not to mention the fresh French bread on the side?” I answer, “I can’t afford that right now.”)

Heh.
