Should we be supplementing, or not?
As is often the case, the science is iffy. I’m taking 5000 IU of D3 daily (or at least when I remember to take anything). No idea if it’s helping, but I don’t generally spend a lot of time in the sun. In fact, I have a solar-powered watch whose battery occasionally runs down because I spend so much time in my office. So it seems likely that I’m somewhat deficient.
Time to throw in the towel on the theory. Like climate, genetics remains a lot more complicated than we’d like to think.
The first one has arrived. The big advantage of this, according to a Twitter discussion with Derek, is that dosage times are much less critical.
…grown from a spinach leaf. Well, that’s…different. But whatever works.
Turns out that bone marrow isn’t the only place that blood is made.
I think a little humility is in order on how much we still don’t understand about the human body.

Surprise, surprise, the testes are connected to the immune system.
In the latest paper, the scientists revealed new details on how NAD+ works to keep cells young. Sinclair put drops of NAD+ into the water of a group of mice, and within a couple of hours, their NAD+ levels started to rise. Within the first week, the scientists saw obvious age reversal in muscle and improvements in DNA repair. “We can’t tell the difference between the tissues from an old mouse that is two years old versus a young mouse that is three to four months old,” Sinclair says.
I’ve started taking it myself. And this is interesting, too:
“The idea is to protect the body from radiation exposure here on earth, either naturally occurring or doctor-inflicted,” he says. “If I were going to have an X-ray or a CT scan, I would take NMN beforehand.” He already has plans to go even farther than earth: NASA is collaborating with Sinclair’s group on the human tests to see if it’s possible to insulate astronauts from the effects of cosmic radiation in space.
That would be nice.
[Sunday-afternoon update]
This looks like a promising similar breakthrough.

Byron York has a good analysis. This is a key point, which was entirely predictable:
‘The Art of the Deal’ doesn’t work with ideologically-driven politicians. The pundits mentioned Trump’s most famous book thousands of times during the Obamacare negotiations. But in dealing with the doctrinaire conservatives in the House Freedom Caucus, Trump was facing differently-motivated partners than in the deal-making recounted in his 1987 book. If the president wants to succeed in Washington, he’ll have to learn how to deal with people who aren’t in it just for the money.
I'd also note that today was the day that Trump finally figured out that he's not the CEO of the country, and the limits of the presidency.

Inside the Trumpcare meltdown.
Rookies.
I don’t care how many there are, still nope. Also not going to cook with it. But it might be useful news for women (and some men).
Why the argument for single payer is economically ignorant. Health-care expenditures are only one factor among many that affect life expectancy.
Other physical challenges are more difficult to address and also less acute. Humans in space suffer muscle and bone atrophy. Space travel requires exposure to increased levels of radiation, which can lead to surprising visual effects. “All of a sudden you will see this really intense, bright white … and then it will fade back out,” says Garriott de Cayeux. “That is basically you being damaged by radiation, it triggers the impression of light even though there is no light.”
His time in space required a year of difficult preparation, although physical fitness wasn’t a focus. “If you’re going on a space walk, you need to be in excellent physical condition, because an inflated space suit is hard to bend. But if you’re not, you just need to be healthy,” he says. Still, SpaceX’s tourism clients will likely be studied head to toe, undergoing a battery of medical tests they’ve probably never heard of before. “In my case, they found I was missing a vein on one lobe of my liver,” says Garriott de Cayeux. “On Earth that’s irrelevant, but in space it could have led to internal bleeding, which is why I ended up having surgery to remove that lobe.”
Yes, word of mouth will dissuade and reduce the market, but many will still find it worth it. and
