“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?

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?

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.

Green Gullibility

…and hyperpartisanship:

What we have here is a death spiral: the worse things get for the movement, the more scrupulously and cautiously it needs to behave, but the more incautiously and emotionally it becomes — leading to more failure and worse advocacy.

The root cause of all this remains, in VM’s opinion, a truly idiotic set of policy proposals that, no matter the state of the underlying science, simply cannot and will not be implemented.

Those whom the gods would destroy, they first make green. Just ask Peter Gleick.

To get back to the source material for Mead’s post, this phenomenon of conservatives/libertarians comprehending the left’s positions much better than vice versa is just a special case. Jonathan Haidt has an interesting piece in this month’s issue of Reason (not on line yet) on the consistent and persistent asymmetry of this miscomprehension, which is described in a review of his book at the New York Times:

The hardest part, Haidt finds, is getting liberals to open their minds. Anecdotally, he reports that when he talks about authority, loyalty and sanctity, many people in the audience spurn these ideas as the seeds of racism, sexism and homophobia. And in a survey of 2,000 Americans, Haidt found that self-described liberals, especially those who called themselves “very liberal,” were worse at predicting the moral judgments of moderates and conservatives than moderates and conservatives were at predicting the moral judgments of liberals. Liberals don’t understand conservative values. And they can’t recognize this failing, because they’re so convinced of their rationality, open-mindedness and enlightenment.

From the Reason article:

We asked more than 2,000 American visitors to fill out the Moral Foundations Questionnaire. One-third of the time they were asked to fill it out normally, answer as themselves. One-third of the time they were asked to fill it out as they think a “typical liberal” would respond. One-third of the time they were asked to fill it out as a “typical conservative” would respond. This design allowed us to examine the stereotypes that each side held about the other. More important, it allowed us to assess how accurate they were by comparing peoples’ expectations about “typical” partisans to the actual responses from partisans on the left and right. Who was best able to pretend to be the other?

The results were clear and consistent. Moderates and conservatives were most accurate in their predictions, whether they were pretending to be liberals or conservatives. Liberals were least accurate, especially those who described themselves as “very liberal.” The biggest errors in the study came when liberals answer care and fairness questions while pretending to be conservatives. When faced with statements such as “one of the worst things one can do is to hurt a defenseless animal” or “justice is the most important requirement for a society,” liberals assumed that conservatives would disagree. If you have a moral matrix built primarily on intuitions about care and fairness (as equality) and you listen to the Reagan narrative, what else could you think? Reagan seems completely unconcerned about the welfare of drug addicts, poor people and gay people. He is more interested in fighting wars and telling people how to run their sex lives.

If you don’t see that Reagan is pursuing positive values of loyalty, authority and sanctity, you almost have to conclude that Republican see no positive value in care and fairness. You might even go so far as Michael Feingold, theater critic for The Village Voice, when he wrote in 2004, “Republicans don’t believe in the imagination, partly because so few of them have one, but mostly because it gets in the way of their chosen work, which is to destroy the human race and the planet…Which is why I personally think they should be exterminated before they cause any more harm.” One of the [many] ironies in this quotation is that is shows the inability of a theater critic–who skillfully enters fantastical imaginary worlds for a living–to imagine that Republicans operate within a moral matrix that differs from his own.

Not also the leftist eliminationist rhetoric from the people who deign to lecture us, the great unwashed, about civility.

As I said, Gleick was just a special case of this broader problem. Many of the leftist warm mongers continue to fantasize that the faked Heartland document is real, while it was almost immediately obvious to those on the other side, even those sympathetic to the AGW thesis, like Megan McArdle, that it was faked, because no conservative would have written such a thing in such a way. Gleick wrote it that way, and his partners in fraud thought it perfectly plausible, exactly because they lack this ability to understand the motivations of their political opponents.

Here’s another example of the new civility: Twitter explodes with Cheney hate after his heart transplant. Aren’t these people sweet? And more proof that they can’t imagine that Dick Cheney may not be evil.

Diminished Climate Alarmism

Lessons from l’affaire Heartland:

The Heartland affair has shown not merely that some climate alarmists (namely Gleick) will stoop to outright deception, and most of his peers will close ranks to defend him in a sort of Green Wall of Silence. Perhaps more disturbing, it reveals that these people really have no idea how their opponents on the climate issue actually view the world. So when they dismiss skeptics as having no legitimate arguments, it should make outsiders take pause.

Without being a trained climate scientist, I can read the various blogs and try to parse the academic papers, but ultimately I have to rely a lot on the good faith and judgment of the scientists themselves. The Heartland affair has reassured my earlier conviction that the case for climate alarmism is far weaker than the alarmists have been telling us.

His emphasis. I think it applies to how the Left views its skeptics in general.

Straight People

Are they born that way?

I know I was. And if someone “self identifies” as straight, but shows signs of arousal by the same sex, they’re not straight, they’re bi. I don’t understand why the concept of a spectrum, a distribution from pure homosexual through bisexual to pure heterosexual, skewed toward the latter, is such a hard concept for people to get their heads around.
