The 28th edition of Gene Genie has been posted at Greg Laden's Blog [Gene Genie #24]. (It really is number 28, in spite of what Greg says. See Gene Genie.)Welcome to Gene Genie #24: with a heavy emphasis on Personal Genetics.The beautiful logo was created by Ricardo at My Biotech Life.
I'm sure you've already heard the news. The Canadian women's team of Dawn Askin (lead), Jill Officer (second), Cathy Overton-Clapham (third) and Jennifer Jones (skip) beat China yesterday to win the World1 Women's Curling Championship.1. Just to clarify for my American friends ... this was not a tournament where only teenagers in colleges like UNC could play and it was not a tournament confined to a single country. This is a world title. The USA didn't even make the playoffs.

This is a very important enzyme. Most living organisms on this planet could not survive if this enzyme didn't do its job. Very few species have this enzyme but we depend on those few species for our very existence.

Darn. I guess I’ll have to take a rain check on that apology – because I don’t agree with this – and not just because Maurice et al. (2008) are cited incorrectly. Here’s why.Biological evolution never means just change over time, but that's not the real problem with Wells' post. You're going to have to scoot on over to Evolution News & Views and read the whole thing.
"Evolution" has many meanings. It can mean simply "change over time." The present is different from the past. The cosmos evolves. Technology evolves. No sane person denies evolution in this sense.

Yesterday's issue of the Toronto Star had an article on The fundamentalist atheists.Hedges, in Toronto recently to promote his book, attacks both fundamentalists and the new breed of atheists as not only intolerant, but wrong about both the Jesus story and the nature of sin.Sin, as I understand it, is when you violate a moral rule of some kind. It usually means you are disobeying the wishes of supernatural beings. It's not a word used by atheists.
Sin, he says, is a personal thing that will always be with us. Humans will never outgrow it through evolution, as the atheist authors contend, nor can anyone (Jesus included) relieve us of it, as fundamentalist Christians believe, Hedges says.
The best we can do, he says, is try to mitigate evil by living a good life, and having democratic institutions in place to ensure that we can get rid of bad leaders from time to time.
For fundamentalists, evil and sin are an external force – often represented by Satan – to be vanquished by giving yourself over to Jesus. For the new atheists, evil and sin are the fault of religion, and can be defeated by getting rid of all religion and giving yourself over to scientific, reasoned thought.Just because religions can be evil does not mean that all evil is due to religion. No atheist believes this, as far as I know.
For Hedges, it's the same argument: People are basically good, but external forces make us do bad things. Get rid of those forces, and people will be good.
No more effort is needed to achieve utopia, he says.
Hedges draws a distinction between the new breed of atheists and such past non-believers as Albert Camus or scientists of the Enlightenment, whose skepticism he says helped drive human knowledge and understanding.The "new atheists" claim there are no supernatural beings because there's no evidence of such beings. This has nothing to do with evil and sin. When are these sophisticated Christians going to address the real question instead of going off on weird tangents? If they have a good argument for the existence of god then let's hear it. Otherwise, their "sophistication" looks more like "obfuscation" to me. (Or like The Emperor's New Clothes and the Courtier's Reply.)
But Hedges has few such hopes for the new atheists. Where atheists of the past used their disbelief as a stepping off point to find something else to believe in, the new atheists claim to have already found it in what he calls a "cult of science."
Anything that can't be proved scientifically is simply discounted, Hedges says, warning that such a narrow approach to study thwarts the pursuit of knowledge by denying a voice to those who disagree.

Amazingly, the best selling Oxford scientist/author Richard Dawkins also crashed a showing of Expelled in Minnesota last night and he not only was let in, but introduced at the end of the showing.Those of you who have been following the issue on the various blogs, and in newspaper articles, know full well that Dawkins did not "crash" the movie. People did not have to be invited and there were no tickets. Chapman and his friends must know this too. Therefore, he is lying.
Dawkins apparently acknowledged that he had not been invited and did not have a ticket. A sophomoric side to his ideological campaign is thus revealed.
Dawkins, understandably is nervous about this film, among other reasons because Ben Stein has him on camera acknowledging that life on Earth may, indeed, have been intelligently designed, but that it had to have been accomplished by space aliens! This is hilarious, of course, because Dawkins is death on intelligent design. But it turns out that that view applies only if it includes the possibility that the designer might be God.
Myers, of course, relished being expelled from Expelled, but objective observers know that Myers is the most vociferous advocate of expelling Darwin critics from academia. Not from movie pre-screenings where he wasn’t invited, mind you, but from their jobs. Too bad the film doesn’t show (and I wish it had), his promotion of advice to attack teachers and professors who dare question Darwin’s theory. The whole point of Myers is that he is a take-no-prisoners, crusading atheist scientist who has made it his purpose in life to harass people who disagree with him. Dawkins turns out to be his buddy and mutual admirer.

By now you've all heard the news. PZ Myers was standing in line to see a screening of the propaganda movie EXPELLED when security guards asked him to leave. They didn't bother with his family or his friend, Richard Dawkins. Read PZ's account at EXPELLED!. I just happened to be standing directly in line behind Dawkins’ academic colleague. Management of the movie theatre saw a man apparently hustling and bothering several invited attendees, apparently trying to disrupt the viewing or sneak in. Management then approached the man, asked him if he had a ticket, and when he confirmed that he didn’t, they then escorted him off the premises. Nowhere was one of the film’s producers to be found, and the man certainly didn’t identify himself. If a producer had been nearby, it’s possible that he would have been admitted, but the theatre’s management didn’t want to take any chances.This sounds very much like a blatant, bare-faced, lie. Anyone who knows PZ Myers would know that he would bot be "hustling" and "bothering" the people waiting in line. Quite the contrary, PZ and his colleague Richard Dawkins would have been trying to keep a low profile.
Framing has not been without controversy, as some have viewed it as little more than a form of empty platitude or an attempt to dumb down science. What became clear from Nisbet's talk, however, is that there can also be people left out of the ostensibly-shared values; it should be no surprise they are objecting.
Ruth Cronje is a faculty member of the Scientific and Technical Writing Program at the University of Wisconsin-Eau Claire in Eau Claire, WI (USA). She has written a letter that was published in Science last week [Going Public with the Scientific Process]. Many of you will never get to read it but you should. It is wonderful. The idea of using framing strategies to communicate science to the public has recently been taken up in scientific forums (1, 2), the mainstream media (3), and the blogosphere (4, 5). Most participants in the framing science debate limit their notion of scientific information to scientific facts. However, confining science messages to just the facts interferes with public understanding of science as a systematic, logical process of human inquiry and effaces the distinction between data and scientists' reasoning about data. To communicate successfully, we should focus on scientific process by emphasizing two important elements of scientific rationality: skepticism and dynamicism (6, 7).In case Mathews and Nisbet don't get it, the new version of Science journal isn't going to let them get away with distorting science for political ends. Nisbet comments on this letter and hopes to discuss the topic with Cronje when he visits her next week [At Science, Still More Reaction to Framing]. I'd love to be there.
Scientists deliberately integrate skepticism into their procedures by trying to refute their own hypotheses, retaining them only when confronted with compelling evidence sought through carefully controlled procedures. Scientists tend to shy away from revealing the intrinsic skepticism of science to the public, fearful that it will open the door to doubt about the validity of their conclusions. But communicating only the facts of science (framed or unframed) destabilizes public confidence in science. A fact doesn't allow science communicators to reveal, justify, and ultimately promote the skeptical reasoning process that helps make scientists more confident that their reasoning is correct.
Science is also dynamic; it is a cumulative enterprise that requires scientists to situate their instrumental activities and interpretations against the evidence that has come before and to alter them in light of new evidence. Insisting that new data be interpreted within the context of past and future data will ferret out and correct error over time, but it means that a fact cannot, by definition, be anything more than the (ephemeral and fallible) consensus of scientists at a given point in time. A "just the facts" strategy can and often does backfire, ultimately fueling public alienation from science. When scientists inform the public of "facts" (like the "fact" widely disseminated in the 1970s that all dietary fats are bad for us), and then that "fact" is refined or altered (now we're told olive oil is good for us), the public is justifiably confused. Studies suggest that the public tends to regard normal scientific refinement and self-correction as equivocation or incompetence (8-10). Instead of sweeping uncertainty under the rug, science communicators should help the public understand the logical and systematic procedures by which scientists confront it.
The true majesty and promise of science lies in its systematic, logical, skeptical, and dynamic reasoning procedures. "Successful" science communication should not be regarded as any message that enlists public support for science. Rather, we should define "success" in scientific communication as achieving a public that celebrates scientific reasoning procedures.
Bruce Alberts, the former President of the National Academies (USA), has now taken over as Editor-in-Chief of Science.1 Judging by his editorial in this week's issue [Considering Science Education] there could be some interesting times ahead in the Science offices. I consider science education to be critically important to both science and the world, and I shall frequently address this topic on this page. Let’s start with a big-picture view. The scientific enterprise has greatly advanced our understanding of the natural world and has thereby enabled the creation of countless medicines and useful devices. It has also led to behaviors that have improved lives. The public appreciates these practical benefits of science, and science and scientists are generally respected, even by those who are not familiar with how science works or what exactly it has discovered.Those of you who have been reading Sandwalk know that this is exactly how I think science education should be fixed. We need to teach students how to think like a scientist. The facts of science are important but they aren't nearly as important as the way in which scientific facts are determined. Science is a way of knowing—that's what students need to learn.
But society may less appreciate the advantage of having everyone aquire, as part of their formal education, the ways of thinking and behaving that are central to the practice of successful science: scientific habits of mind. These habits include a skeptical attitude toward dogmatic claims and a strong desire for logic and evidence. As famed astronomer Carl Sagan put it, science is our best “bunk” detector. Individuals and societies clearly need a means to logically test the onslaught of constant clever attempts to manipulate our purchasing and political decisions. They also need to challenge what is irrational, including the intolerance that fuels so many regional and global conflicts.
So how does this relate to science education? Might it be possible to encourage, across the world, scientific habits of mind, so as to create more rational societies everywhere? In principle, a vigorous expansion of science education could provide the world with such an opportunity, but only if scientists, educators, and policy-makers redefine the goals of science education, beginning with college-level teaching. Rather than only conveying what science has discovered about the natural world, as is done now in most countries, a top priority should be to empower all students with the knowledge and practice of how to think like a scientist.
