“Ignorance of how evolution works is amazing to behold” … or, Happy Birthday Mike!

That’s The Mike, of Tangled Up in Blue Guy, and Quiche Moraine.

The title of this post, “Ignorance of how evolution works is amazing to behold. ” is a quote from one of my favorite (recent) posts by TUIB Guy, which is called: The Agony and The Irony. A close second is Logic and Perspective. Please stop over at Mike’s blog, wish him a happy birthday, and have a look at these posts.

Major Upgrade for Goddard Climate Simulation Machine

In August, Goddard added 4,128 new-generation Intel “Nehalem” processors to its Discover high-end computing system. The upgraded Discover will serve as the centerpiece of a new climate simulation capability at Goddard. Discover will host NASA’s modeling contributions to the Intergovernmental Panel on Climate Change (IPCC), the leading scientific organization for assessing climate change, and other national and international climate initiatives.

And they’re adding another 4,128 in a couple of months. This will be the first major. Nehalem based climate simulation project. Details here.

Income, IQ, and profession

Research from Bristol:

Doctors and lawyers are more likely to come from wealthy backgrounds according to new research from the Department of Economics that indicates that the ‘social gap’ that prevents poorer people from entering the top professions is becoming more pronounced over time.

Using data on family income and IQ in childhood drawn from the National Child Development Survey (NCDS), which tracks a representative sample of the population born in 1958, and the British Cohort Study (BCS), which follows people born in 1970, the research shows that professions such as law and medicine attract better-off people, compared with other professions such as teaching and nursing, although differences in IQ test scores for the former decreased over time.

On the other hand, those who became engineers and nurses – two professions with the lowest average family incomes across the groups and the lowest IQ scores for those born in 1958 – appear to buck this trend with the average IQ scores for both professions increasing over time.

Tiniest Photograph Ever Explained

I posted a photo of a itty bitty molecule that is making the news these days … the photo, not the molecule … but I didn’t have much to say about it except that it was cool. Ethan Siegel has picked up the thread and explains what it is we are looking at.

I myself have used the little needle thingie in research, but the tip of the one I used was more like an actual needle made of a zillion metal molecules so we could only image things like primate teeth or cut marks on bones. This one is a little different…

Should stim-bucks be linked to school test scores?

DURHAM, N.C. — Two Duke University education experts have serious concerns about the Obama administration’s proposal to link teacher evaluations to student tests scores as a criterion for how much federal stimulus money states will receive for K-12 education.

Friday (Aug. 28) is the deadline to submit public comments on the proposal that will disperse more than $4 billion in grants. The U.S. Department of Education has said it will issue its final rules sometime after the deadline.

Helen F. Ladd, the Edgar Thompson Professor of Public Policy at Duke, says that while student test scores play a role in the overall effort to improve schools, the proposed regulations “give them a pride of place that will lead to little good and is likely to do much harm.”

“The main problem with the heavy focus of the proposed test-based approach is that it ratchets up the pernicious narrow test-based approach to education represented by No Child Left Behind,” Ladd says in comments she has submitted on the proposal.

“The approach is narrow in part because the requirement that all students be tested every year means that students can be tested in only a limited number of subjects. The result is a heavy emphasis on the basic skills of math and reading, to the detriment of other skills and orientations that young people need to become effective participants in the global society.

“Further, the emphasis on test results for individual teachers will exacerbate the well-documented incentives for teachers to focus on narrow test-taking skills and drilling. It is time to move beyond this misplaced emphasis on test scores in a few subjects to return to the broader goals of education that have been such an important part of our history.”

You can’t see atomic bonds. Or can you?

Atomic bonds are too small to see, right? Well, what do you suppose THIS is a picture of!?!?!?

That B&W structure is an actual image of a molecule and its atomic bonds. The first of its kind, in fact, and a breakthrough for the crazy IBM scientists in Zurich who spent 20 straight hours staring at the “specimen”–which in this case was a 1.4 nanometer-long pentacene molecule comprised of 22 carbon atoms and 14 hydrogen atoms.

You can actually make out each of those atoms and their bonds, and it’s thanks to this: An atomic force microscope.

Your psychologist could be an Intel chip….

Well, not really, but if on line CBT takes off, how will we know when they make the switch?

Cognitive behavioural therapy (CBT) seems to be effective when delivered online in real time by a therapist, with benefits maintained over 8 months. This method of delivery could broaden access to CBT in primary care. These are the conclusions of an article in this week’s Global Mental Health special edition of The Lancet, written by Dr David Kessler, NIHR National School for Primary Care Research, University of Bristol and colleagues.
