Vitamin D
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.
The Syria Strike
Why did they use Tomahawks? This is a pretty good explanation. As the article says, it was low payoff, but it was also low risk, and could be done quickly without having to coordinate with allies, as symbolism.

What the Syria attack did, and didn’t do.
Passover
For those in a hurry, a cute one-minute haggadah.
Space Corps
Coyote is really pushing this concept. Now he’s got an op-ed at Aviation Week.
The Long Space Age
This looks like an interesting new book
The Farce Awakens
Bad lip reading of the movie. Some of the dialogue is better, really.
On-Line Privacy
The Electronic Freedom Foundation has a guide, now that the rules have been changed to allow your ISP to track you and sell the data.
More Blue Origin News
They’re working on a lunar lander:
Blue Origin would be willing to invest in development of the Blue Moon system as part of a partnership with NASA, Meyerson said, envisioning regular delivery of resources and supplies to a potential lunar colony to augment NASA missions launched by the agency’s own Space Launch System.
“The more NASA flies SLS, the more they will need commercial logistics delivery services,” he said. “New Glenn and Blue Origin and Blue Moon compliment SLS and Orion, enabling NASA’s return to the moon, and this time to stay.”
NASA’s current human spaceflight plans do not include human missions to the lunar surface. Instead, NASA has outlined an an architecture that calls for the development of a human-tended facility in cislunar space, called the Deep Space Gateway, by the mid-2020s intended to support testing of technologies needed for human missions to Mars in the 2030s.
Congress doesn’t really want NASA to do anything except build a giant rocket that hardly ever flies, but Meyerson is being politically correct.
[Update a while later]
ULA has a nice video of their vision for the future.
[Update Friday morning]
Eric Berger talked to Rob Meyerson about Blue Origin’s plans. They’ll be flying again this summer. Passengers next year.
The Seratonin Transporter Gene And Depression
Time to throw in the towel on the theory. Like climate, genetics remains a lot more complicated than we’d like to think.
