“Unilateral Intellectual Disarmament”

Why the Left is losing the argument:

In sum, the left systematically has dumbed its side down, to the point where supposedly well-educated elites are untrained and unaware of our country’s history and constitutional traditions. The left thinks words have no fixed meaning (health care and health insurance, are close enough, so they insist we can define the latter to be the former.) The liberal elites have a poor grounding in market economics so they swallow the idea that health-care insurance is “unique” because others’ purchases affect your cost of goods. (Surprise: all markets operate this way.) They advance illogical and counterfactual arguments (e.g., withdrawing a 100 percent subsidy for health care to seniors is a “mandate”) because they are unused to vigorous debate that upsets their preferences dressed up in a thin veil of factual distortion. (Sorry, taking away a freebie is not remotely the same in logic or in law as requiring you purchase something.)

Conservatives, well aware of the intellectual deterioration of liberal institutions, have spent decades pursing supplemental education in think tanks, the speeches and writings of public intellectuals (e.g., Irving Kristol, James Q. Wilson), professional organizations (e.g., the Federalist society) and classrooms of intellectually rigorous scholars (e.g., Robert P. George, Harvey Mansfield and Richard Epstein). In doing so, they sharpened their rhetorical kills, versed themselves in history and political philosophy, and prepared themselves for intellectual combat against those who had rejected the idea of objective meaning, be it in literature or the Constitution. In moments like the Supreme Court argument we see how vast is the gulf between conservative and liberal elites.

Just another example of Haidt’s thesis.

Another Reason To Eat Chiles

They reduce blood pressure and cholesterol. This kind of thing always makes me question such studies, though:

Chen and his colleagues turned to hamsters for the study, animals that serve as stand-ins for humans in research that cannot be done in people. They gave the hamsters high-cholesterol diets, divided them into groups, and supplemented each group’s food with either no capsaicinoids (the control group) or various amounts of capsaicinoids. The scientists then analyzed the effects.

In addition to reducing total cholesterol levels in the blood, capsaicinoids reduced levels of the so-called “bad” cholesterol (which deposits into blood vessels), but did not affect levels of so-called “good” cholesterol. The team found indications that capsaicinoids may reduce the size of deposits that already have formed in blood vessels, narrowing arteries in ways that can lead to heart attacks or strokes.

Capsaicinoids also blocked the activity of a gene that produces cyclooxygenase-2, a substance that makes the muscles around blood vessels constrict. By blocking it, muscles can relax and widen, allowing more blood to flow.

Emphasis mine. The assumption is that one gets high cholesterol from dietary cholesterol, when in fact there’s little evidence to substantiate that. But in this case, I don’t think it invalidates the research, fortunately.

Speaking of nutrition myths, here’s one that says bacon is good for you, but still gets it wrong:

Nutritionist Zoe Harcombe says: ‘Typically, about 45 per cent of the fat in pork is unsaturated. Most of that is oleic acid, the same healthy fat found in olive oil, which is known to help lower cholesterol levels.

‘Of course, the rest is unhealthy saturated fat, so moderation is key.’

Repeat after me: there is nothing wrong with saturated fat. In fact, it is much healthier than seed oils with their high omega 6s, which is where we got too much of our dietary fat. The key is to cut back on the high-glycemic carbs.

“An RC Robotic Claw”

Is anyone else annoyed by that Chevron commercial with the kid talking about the thing that her “science” teacher helped her build? I’ve no problem with kids learning stuff like that, but it isn’t “science.” It’s engineering. This kind of thing (like the phrase “rocket scientist”) just promulgates false notions of what science is and isn’t, and doesn’t do much to make sure that kids are taught real science (and no, being taught real science also isn’t being taught that ZOMGaia we’re destroying the Earth!).

A Breakthrough?

A single anti-body that shrinks a wide variety of human tumors in mice.

They showed that nearly every human cancer cell they examined expressed CD47 — usually at higher levels (on average, about three times more) than did non-cancerous cells. Furthermore, people whose cancer cells express a lot of CD47 tend to have shorter life spans than people with similar cancers that express less CD47. This suggests that an analysis of the levels of CD47 expression in some types of tumors could be a valuable prognostic tool for patients and their doctors.

Willingham and Volkmer then implanted the different human tumor cells into matching locations in the bodies of mice — breast cancer tumors into the mammary fat pads, and ovarian cancer tumors into the abdomen, for example. Once the tumors were well-established (after two weeks or more), they treated the animals with the anti-CD47 antibody.

The researchers saw that most of the established tumors begin to shrink and even, in some cases, disappear within weeks of treatment with the antibody. In one case, antibody treatment cured five mice injected with the same human breast cancer cells. When the tumor was gone, the treatment was discontinued; the mice were monitored for four months with no signs of recurrence.

“These results indicate that anti-CD47 antibodies can dramatically inhibit the growth of human solid tumors by blocking the ability of CD47 to transmit the ‘don’t-eat-me’ signal to macrophages,” concluded the authors.

Clinical trials for humans within two years?

Faster, please.

Bad Cholesterol

…is there no such thing?

I’m kind of amused by the commenter who fantasizes that he’s making some kind of point by claiming that “Eades is not a scientist.” What does he think a scientist is, or does?

[Update a few minutes later]

Speaking of nutritional science, this is junk nutritional science:

“Overall, we found that obese rats fed a high-fat, low-carb diet — comparable to that humans would consume — had larger, more damaging and deadly heart attacks than rats fed the control diet,” Lloyd says. “Our findings also suggest that, at the cellular level, a high-fat, low-carb diet impaired recovery of heart function in obese rats immediately following a heart attack.”

Only one problem. You can’t extrapolate dietary results for rats to humans. We have a different physiology and natural diet. Actually, there’s a lot of junk science based on rat research.
