For people interested in non-terrestrial life, this should be a higher priority than Europa. It’s farther away, but a much more benign radiation environment.

On Boundary Conditions And Initial Values
An interesting paper at Judith Curry’s site (which is a go-to place for people following the climate follies).
Once again, for the record, I find literally incredible the notion that we have either the understanding of the physical interactions or the computer power to predict future climate with any useful confidence.
The Risk Of Spaceflight
A new paper assessing spaceflight mortality. Not sure how useful it is, given the admitted paucity of data.
[Update a few minutes later]
When a Mars simulation goes wrong. Yes, we have a lot to learn before we go to other planets, and even then, people will die, often in terrible ways. Part of the answer is that we have to be more ambitious about how many we send. Six simply isn’t enough.
Methane On Mars
Tanya Harrison has the story. As always, a reminder that people who want to settle Mars should hope that we don’t find life there.
The Jaguar
…is made for the age of humans. A nice nature piece from Nadia Drake.
And though this is a leopard, not a jaguar, it’s interesting.
It's always seemed pretty clear to me that my cats knew what a mirror was, and didn't treat it like another cat. But maybe the leopard is figuring it out. https://t.co/8z4UnokOs6

Fasting
It may aid in the regeneration of stem cells. I do this almost every day. Not quite 24 hours, but I often don’t eat from when I go to bed until dinner the next evening. Other than morning coffee, which I don’t think would count, given its utter lack of nutrients.
Simone Giertz
This is terrible news. But she’s tough, she’ll beat this thing.
[Afternoon update\
There are two gofundme pages for this. I can’t make any recommendations about either one.
Preventing Aging
Is it mathematically impossible?
I haven’t read the article in detail, but I doubt it. I suspect they’re going after a straw man.
The History Of Sugar And Its Health Impacts
An interesting interview with Gary Taubes:
In the science in which I was raised—physics and chemistry, the hard sciences—the last thing you want to do is get an assumption accepted into the theory of how things work without rigorously testing it, because then people will build on it and it will grow and infect the whole thought construction. You end up with, I’m going to beat this metaphor to death, but sort of a house of cards. And there will be no way to go back on it. In a field like nutrition and obesity research, you’ve now got these enormous institutional dogmas built in that I and others are arguing are simply wrong. How do you get the institutions to change their belief systems?
The British Medical Journal is running a series on nutrition policy, and their way of dealing with it is by assigning writers from these different belief systems. So I’m a co-author on an article on dietary fat, along with the former head of the Harvard nutrition department who thinks I’m the worst journalist he’s ever met and who does a form of science that I consider a pseudoscience.
It’s just nuts.
Genetics And Racial Quotas
Michael Barone points out the obvious.
