And human trials start next year.

The Book Review You’ve Been Waiting For
Paul Ehrlich, on Mark Steyn’s latest.
Desalinating Water
I wonder if there’s a catch? If not, this would be revolutionary.
Synthetic Messenger RNA
…to tell our bodies how to manufacture their own medicine.
Cool, if it works. Faster, please.
Back In LA
I was scheduled to come home this evening, but I had no other business in Seattle, and it turned out that Alaska lets you change flights same day for only $25, so I actually caught a 6 AM flight.
The bad news is that Fedora doesn’t seem to want to boot into the 4.2.5 kernel, in either Fedora 22 or Fedora 23 (I hoped upgrading to the latter would fix). It just bombs out and loops in a continual effort to boot. I had to revert to 4.1 to boot it. Not sure how to diagnose. I’ve seen hints that others are having similar problems in the Fedora fora, but no indication of what to do about it.
The Learning Period For Regulating Spaceflight Participant Safety
It will be extended until 2023.
If we haven’t started flying by then, we might as well give up.
Tethers Unlimited
Just had an interesting visit there, where they’re working on a lot of tech that will reduce (to the limited degree it exists) the justification for large-fairing launch payloads, with new orbital-assembly techniques, including 3-D printing. They’re working on (among other things) ways of building large lightweight trusses for orbital structure, that could lead ultimately to assembly hangars. They’re also developing ways to recycle a lot of plastic goods (like bubble wrap and zip locks) into cord to feed 3-D printers at the ISS. Very exciting stuff.
More Nutrition Junk Science
http://www.the-scientist.com/?articles.view/articleNo/44302/title/The-6-000-Calorie-Diet/. Particularly the praise of it. There are no lessons to be learned from it except don’t eat a lot of crap. Calories are totally irrelevant, but it seems to be the focus of the study.
In Seattle
I had a long trip to get here, starting at 2:30 AM Central (two-hour bus ride from Columbia MO to St. Louis, two-hour plane ride to Charlotte, five-hour plane ride to Seattle), but I’m at the Museum of Flight, where I’ll be giving a talk and book signing tomorrow, for any Seattlites who want to show up. It’s $20 admission to the Spacefest, but it’s an opportunity for a signed book if you don’t have one.
I’ve never been here this time of year. I was surprised at the fall colors.
My Vegan Diet
“…almost killed me“:
Her public profile hinged on her vegan identity, yet her choices were damaging her body. Often she felt so weak, she had to work on her laptop computer from bed. Taking one yoga class would leave her drained for the whole day.
Younger’s turning point came in June 2014, exactly a year after she founded her blog, when she confided in a friend about her lack of menstruation — a condition medically known as amenorrhea — for at least six months.
The pal, who had also suffered from orthorexia, recommended she introduce fish into her diet. Soon afterward, Younger forced herself to eat a small portion of wild salmon — and, within a week, her period was restored.
“It showed me how my body was dying to get back on track,” she says, adding that she instantly started to feel more energetic.
A dietician confirmed that fish and eggs would boost her poor nutrient levels. Refusing to lie to her fans, Younger announced on her blog that same month that she was “transitioning away from veganism.”
That’s when all hell broke loose. Her site crashed within two minutes and 1,000 followers instantly ditched her. Worse, she received anonymous death threats from hard-core vegans claiming she condoned the slaughter of animals and that neither she nor her family had the right to live.
Vegans can be such nice people.
