Zombies Versus Animals

14 Comments

Don’t worry, wildlife would kick undead ass:

…zombies are essentially walking carrion, and Mother Nature doesn’t let anything go to waste.

Yup.

[Update a few minutes later]

It’s really worth a read:

North America’s large mammal predators would be more than a match for zombies. We have two bear species, brown (or grizzly) and black bears. Male brown bears can weigh in at 1,000 pounds. They are not afraid of humans. They can deliver a bite of 1200 pounds per square inch and have long, sharp claws designed to rip open logs and flip boulders in search of insects and other small critters to eat. They would easily tear apart rotting zombie flesh. Black bears are much smaller and typically run from humans, but even a black bear, when approached or cornered, would make short work of a zombie. Both bear species have an incredible sense of smell and both love to eat carrion, so even if zombies didn’t approach them, the bears eventually would learn that these walking bags of flesh make good eating.

Like black bears, gray wolves are very shy of humans and typically run away at the first sight of us. Nor are they strangers to scavenging. They’d soon take advantage of the easy pickings presented by lumbering zombies. Coyotes are far less shy than wolves and can happily live alongside humans, including in the heart of our cities. These intelligent canids would quickly learn that they could take down zombies one by one, especially the eastern populations of coyote, which are larger and bolder due to past interbreeding with wolves and domestic dogs.

Though I’d point out that it they think black bears are shy around humans, they’ve never run across one in Alaska. They’re very aggressive up there — Alaskans seem to fear them more than grizzlies, which will generally leave you alone if you don’t surprise them. I suspect it’s because they’re much less used to humans, with the low population density. It’s almost like they’re a different species from the lower forty nine. Alaska would be a particularly gruesome place to be walking dead. The moose alone would make quick work of them.

Irrational “Liberal” Hate

4 Comments

Dissecting the anti-Keystone nonsense:

So what is going on here? Rich liberals hire kids–recent college graduates, or maybe college or high school students–to produce idiotic “research reports” that can be dismantled by anyone familiar with arithmetic, let alone the oil and gas industry, of which these kids obviously know nothing at all. The claims these reports make are completely divorced from reality, but liberals don’t seem to care. The Huffington Post headlines: “Keystone XL Pipeline Could Yield $100 Billion For Koch Brothers.” PolicyMic: “Actually, You Probably WILL Guess Who Stands to Make $100 Billion Off the Keystone XL Pipeline.” TruthDig: “Koch Brothers Stand to Make $100 Billion From Keystone Pipeline.” And, of course, the Kos Kidz are all over it.

Imbecility.

Is Science Self Correcting?

13 Comments

Scientists wish, but it’s not. At least in the short term:

Academic scientists readily acknowledge that they often get things wrong. But they also hold fast to the idea that these errors get corrected over time as other scientists try to take the work further. Evidence that many more dodgy results are published than are subsequently corrected or withdrawn calls that much-vaunted capacity for self-correction into question. There are errors in a lot more of the scientific papers being published, written about and acted on than anyone would normally suppose, or like to think.

Various factors contribute to the problem. Statistical mistakes are widespread. The peer reviewers who evaluate papers before journals commit to publishing them are much worse at spotting mistakes than they or others appreciate. Professional pressure, competition and ambition push scientists to publish more quickly than would be wise. A career structure which lays great stress on publishing copious papers exacerbates all these problems. “There is no cost to getting things wrong,” says Brian Nosek, a psychologist at the University of Virginia who has taken an interest in his discipline’s persistent errors. “The cost is not getting them published.”

Yup. And peer review is not much of a quality control, when it becomes “pal review.”

This partially explains why there’s so much crap science in climate research. Probably for nutrition as well.

Read the whole thing. Undue faith in the current process of evaluating and correcting junk science will be appropriately reduced.

Oh, and then there’s this:

Statisticians have ways to deal with such problems. But most scientists are not statisticians.

Professor Hockey Stick certainly isn’t. Which is why it was so easy for people who do understand statistics to publicly pull his Nobel-winning pants down. And of course, Paul Krugman isn’t, either.

OK, one more excerpt, just to demonstrate why you should RTWT:

The idea that there are a lot of uncorrected flaws in published studies may seem hard to square with the fact that almost all of them will have been through peer-review. This sort of scrutiny by disinterested experts—acting out of a sense of professional obligation, rather than for pay—is often said to make the scientific literature particularly reliable. In practice it is poor at detecting many types of error.

John Bohannon, a biologist at Harvard, recently submitted a pseudonymous paper on the effects of a chemical derived from lichen on cancer cells to 304 journals describing themselves as using peer review. An unusual move; but it was an unusual paper, concocted wholesale and stuffed with clangers in study design, analysis and interpretation of results. Receiving this dog’s dinner from a fictitious researcher at a made up university, 157 of the journals accepted it for publication.

Dr Bohannon’s sting was directed at the lower tier of academic journals. But in a classic 1998 study Fiona Godlee, editor of the prestigious British Medical Journal, sent an article containing eight deliberate mistakes in study design, analysis and interpretation to more than 200 of the BMJ’s regular reviewers. Not one picked out all the mistakes. On average, they reported fewer than two; some did not spot any.

And yet some people think that we should base multi-trillion-dollar policy decisions on this crap.

The Paleo Diet

11 Comments

Is it a fad? An interesting interview by Ben Domenech:

…the existing food movement that sprang up around organic food was largely driven by, particularly in the early years, the vegetarian world and the plant-based diet world, with a good bit of progressive ideology. And so that is alienating to a lot of people who might want to be healthier, who do care about where their food comes from. We saw the same thing happen in the environmental movement. You’ve got scores of hunters who care deeply about conservation and practice it in their own lives, and but due to differences in culture hunters have largely been excluded from the environmental movement.

I think there was a latent demand for an alternative approach to healthy eating and healthy living that wasn’t, that didn’t require you to buy in to all this other ideology. Because basically until paleo, until this general evolutionary approach came along, the only options were, you can be a sort of like a hippie vegan progressive, or you can eat tons of McDonalds and become obese and proudly tout that you don’t care where your food comes from, or you can go on some fad diet. And those aren’t actually very good options for a lot of people.

So, first I just think there was latent demand for it. And then there there’s definitely something to the fact that paleo doesn’t look down on eating meat and that definitely appeals to a slightly more masculine group of folks. The latest surveys have shown that paleo is actually split about 50/50 between men and women, but that’s far more men relative to all other dietary movements, which tend to be 70, 80% women. So, people will say it’s all macho, all these men are into it. It’s actually about 50/50, but it just feels a little bit more masculine relative to everything else.

It really has taken off more among libertarians than the general population, I think.

Popcorn At The Movies

A history.

But here’s a question for paleo types. Yes, I know it’s a grain, and grains are bad, but it’s probably the least processed grain we eat. How bad is it, relatively?

Hmmmmm… [googling]

There seems to be a consensus that it’s definitely not paleo. But some say there are worse things if you’re going to cheat. I saw this one horror story, but I think that’s more a problem of the crap they put on it in the theater than the corn itself. I always pop it in butter, and put butter on it, but there are a lot of recommendations for coconut oil instead..

There are a lot of warnings (appropriately, I think) about the microwaved variety. I have to say, that I hadn’t realized how many paleos are anti-GMO. I think that’s taking it beyond eating healthy, and turning it into a religion.
