It’s not cholesterol, and the best test is dirt cheap. An interesting interview.

Fake Meat
As I tweeted to Ron (he hasn’t responded), my concern is that, being derived from soy, it won’t have the same nutritional value as actual beef.
Reversing Aging
A long but interesting interview with George Church:
Certainly if you could fix all nine hallmarks at once that would do well. Reversal of aging has been demonstrated in simple animals. Some people will dismiss those as too simple — because they have such a short life already, it’s not surprising you can make them live longer. But I think it’s quite clear that aging is programmed in some sense. It’s not like you’ve been programmed to die at some age, but the laziness of evolution has resulted in your program to not avoid dying.
Over evolutionary time, to use analogy, it was not cost effective to invest a lot of your precious food to live longer because you’re going to get eaten by a wolf anyway. Now we have plenty of excess food, and rather than becoming obese let’s spend that on living longer, by spending extra ATP on repair and rejuvenation. That’s something 20-year-olds do fine, but after 60 you stop investing quite as well.
Yes. There has been no evolutionary pressure for us to live longer, but it’s absurd to think it would violate any laws of physics (and ultimately, even biology comes down to physics) that prevent us from living indefinitely long lives. And how soon could it happen?
The simple answer is, I don’t know. Probably we’ll see the first dog trials in the next year or two. If that works, human trials are another two years away, and eight years before they’re done. Once you get a few going and succeeding it’s a positive feedback loop.
That’s pretty exciting, but still: faster, please.
But I did come across this:
If you find that in the western world we’re eating a lot of marbled cow that didn’t exist in the ancient days, all you have to do is get rid of the marbled cow and you’re all set.
Except I’m not aware of any scientific evidence that marbled cow is a problem. I wonder how up on nutrition he is?
How Long Should We Live?
A video that lays bare our irrational acceptance of the reaper.
Speaking of which, Aubrey de Grey gave a great luncheon talk in Austin on Saturday. He wants to live as long as he wants to live, and he thinks that people who want to go into space are crazy, because it’s too risky.
Designer Proteins
Derek Lowe on an interesting new breakthrough.
Flu Vaccines
Why they’re so lousy; they’re grown in eggs.
This always seemed to me like a very inefficient, 20th century manufacturing technique.
Trump And John Roberts
Trump has done what Roberts would not: Start to bring ObamaCare into Constitional compliance.
I continue to believe that there was something very disturbing about Roberts’ last-minute change of position, possible including blackmail. Recent revelations about other instances of the Obama administration spying on its political adversaries do nothing to reduce that belief.
[Update a while later]
ObamaCare was built with intrinsic flaws that Trump is now exploiting. It’s what happens from the hubris of thinking that such landmark social policy doesn’t need bipartisan support.
[Late-night update]
Sorry, everyone, but Trump didn’t instigate the ObamaCare acapolypse.
Nope. It was baked into the cake.
Kale
Is eating it raw bad for you? I always cook it, but now I’m starting to get concerned about other cruciferous veggies. Is cole slaw a problem?
Hearts
…can now survive outside the human body. Of course, this doesn’t solve the problem of where to get the hearts. We need to be able to grow them.
Faster, please.
Concussions
Science writer/editor Elizabeth Lopatto suffered one in a bicycle accident, and wrote about it.
