The lies of embryonic stem cell research

Embryonic stem cell research, contrary to the rhetoric, will NOT lead to a cure for Alzheimer’s.  And it probably won’t for Parkinson’s disease, either.  According to Joe Carter, stem cell scientists know this, but purposefully lie about it to overcome pro-life opposition to the destruction of embryos:

Several years ago I worked for a Christian bioethics think tank when ESCR was being hotly debated in the media. Although the ethics of the issue were contested, there was not much disagreement about the basic science involved. Yet some scientists were making claims about ESCR that no one with even the most basic knowledge about the subject could honestly believe were true. But they fooled others into believing them.

For example, the Democratic Party was so convinced that it included in its 2004 platform the claim that, “Stem cell therapy offers hope to more than 100 million Americans who have serious illnesses—from Alzheimer’s to heart disease to juvenile diabetes to Parkinson’s.” Even at the time, researchers knew that ESCR could never cure such diseases as Alzheimer’s, and would likely never be useful for treating juvenile diabetes or Parkinson’s either.

While all Christian bioethicists were quick to point out that these claims were inaccurate, few were willing to say that the scientists were lying. However, Art Caplan—the “dean of liberal bioethics”—has no qualms about calling them out on their dishonesty.

The Cranach Nuclear Watch

As Japan and the rest of the world worry over what will happen to the earthquake and tsunami damaged nuclear power plants, you should know that here at the Cranach blog we are getting some expert commentary.  MarkB used to work with nuclear power plants, and Carl Vehse–whom you might know merely on this blog as a conservative flamethrower–is by vocation a nuclear chemist.

I appreciate their ongoing explanations of the information that is coming out.

Only 4% of the universe is material

From a review of Richard Panek’s The 4% Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality. Richard Panek:

The latest surveys of the universe indicate that only 4 percent of it is made of ordinary matter. Nearly 23 percent is made up of dark matter, which some physicists suspect consists of wispy subatomic particles that may someday be caught in a detector. And the remaining 73 percent is made up of something far more baffling: an energy that is causing the universe to expand at an ever-increasing rate. Scientists call it “dark energy,” and they have no idea what it is.

Maybe it’s God.

More weird science

According to this article in The New Yorker, when scientists replicate an experiment, the results–proven initially–sometimes change with time.  Drugs that at first are shown to be effective often are shown to be ineffective when tested later.   The article cites one experiment whose results varied when it was performed in different locations.  In many different scientific fields, effects  decline with time.

While Karl Popper imagined falsification occurring with a single, definitive experiment—Galileo refuted Aristotelian mechanics in an afternoon—the process turns out to be much messier than that. Many scientific theories continue to be considered true even after failing numerous experimental tests. Verbal overshadowing might exhibit the decline effect, but it remains extensively relied upon within the field. The same holds for any number of phenomena, from the disappearing benefits of second-generation antipsychotics to the weak coupling ratio exhibited by decaying neutrons, which appears to have fallen by more than ten standard deviations between 1969 and 2001. Even the law of gravity hasn’t always been perfect at predicting real-world phenomena. (In one test, physicists measuring gravity by means of deep boreholes in the Nevada desert found a two-and-a-half-per-cent discrepancy between the theoretical predictions and the actual data.) Despite these findings, second-generation antipsychotics are still widely prescribed, and our model of the neutron hasn’t changed. The law of gravity remains the same.

Such anomalies demonstrate the slipperiness of empiricism. Although many scientific ideas generate conflicting results and suffer from falling effect sizes, they continue to get cited in the textbooks and drive standard medical practice. Why? Because these ideas seem true. Because they make sense. Because we can’t bear to let them go. And this is why the decline effect is so troubling. Not because it reveals the human fallibility of science, in which data are tweaked and beliefs shape perceptions. (Such shortcomings aren’t surprising, at least for scientists.) And not because it reveals that many of our most exciting theories are fleeting fads and will soon be rejected. (That idea has been around since Thomas Kuhn.) The decline effect is troubling because it reminds us how difficult it is to prove anything. We like to pretend that our experiments define the truth for us. But that’s often not the case. Just because an idea is true doesn’t mean it can be proved. And just because an idea can be proved doesn’t mean it’s true. When the experiments are done, we still have to choose what to believe.

“Something close to a creationist” and “potentially evangelical”

A professor passed over for a job because he questioned evolution sued for religious discrimination.  The university has settled:

The University of Kentucky will pay $125,000 to an astronomy professor who sued the school for religious discrimination.

A motion filed Tuesday in U.S. District Court in Lexington said that both UK and C. Martin Gaskell, a research fellow at the University of Texas-Austin, now want the lawsuit thrown out. It had been scheduled to go to trial on Feb. 8.

The lawsuit had provided fodder for Internet news and blog sites discussing religious faith versus academic reasoning.

Gaskell claimed that he was passed over for a job as director of UK’s MacAdam Student Observatory three years ago because of his religion and statements that were perceived to be critical of evolution. He was being represented in the case by attorneys from the American Center for Law and Justice.

Gaskell was a top candidate for the job, according to court filings, but some UK professors called him “something close to a creationist” and “potentially evangelical” in department e-mail messages.

I suspect Prof. Gaskell maintains his beliefs are scientific rather than religious, but surely the University was discriminating against him on the grounds of religion.  The very possibility that he was “potentially evangelical”  was enough for the school to blackball him.
