The SF Signal Mind Meld feature poses science fiction related questions to a number of SF luminaries and the scientist, science writer or blogger. Subjects have included the best women writers in SF, taboo topics in SF, underated authors and the most controversial SF novels of the past and present. The also cover lighter topics, such the role of media tie-ins, how Battlestar Galactica could have ended better (bonus Geoff Ryman) and the realistic (or otherwise) use of science on TV SF shows.

Engineering Perfect Americans Were your immigrant ancestors considered genetically predisposed to become criminals? Were your mixed-ethnic ancestors thought to be polluting the nation's 'germ-plasm'? The Image Archive on the American Eugenics Movement presents a well-put-together online exhibit/walkthrough of this disturbing vein in American history.

Genes Reveal Recent Human Brain Evolution. Two important new papers in the journal Science (available here) from the evolutionary geneticist and rising star, Bruce T. Lahn (see this recent profile from The Scientist), are potentially the tips of some very large icebergs. The papers document how two genes related to brain properties that underwent strong selection during the course of hominid evolution, have continued undergoing strong selection since the emergence of anatomically modern man. The papers wonderfully illustrate how biological evolution is an ongoing process as well as the artificial distinction between “micro” and “macro” evolution, and promise to be controversial for two reasons: First, the brain genes underwent the strongest selection during two periods of cultural and technological efflorescence (roughly 37,000 and 5,800 years ago). Second, the genes are distributed very differently in modern human population groups, existing at very high frequencies in some groups and being very rare in others, ensuring that the modern function of these genes will be a source of more research and much impassioned debate. More observations from anthropologist John Hawks.

Pharmaceutical company seeks approval for controversial heart drug BiDil for blacks only, even though the connection of a nitric oxide deficiency to the genetic makeup of the African-American population is an unsubstantiated hunch, in the words of the drug's own developer — and the drug had already once been denied approval. Is the FDA doing good science or ignoring science under the pressure of big business wanting to sell BiDil to a US$1Bln demographic?

The Natural History of Ashkenazi Intelligence (PDF). A fascinating new theory from physicist turned renegade evolutionary theorist, Gregory Cochran (see this Atlantic Monthly cover story on Cochran's already path-breaking germ theory of disease), and genetic anthropologist Henry Harpending, proposes that a unique evolutionary history, and a number of improbably clustered neurologically related genetic diseases among Ashkenazi Jews could help explain their incredible intelligence test scores and extraordinary intellectual achievements (e.g. Ashkenazi Jews are 3% of the American population but win 27% of the Nobel Prizes). The paper is set for publication in the Journal of Biosocial Science, and is already getting major press in the New York Times and The Economist. Does the recent Harvard fracas over Larry Summers herald a new "arms race" in academic debate about genetics, man and society for the 21st century? [compelling post by Jason]

A hundred social scientists and geneticists gathered this week in Alexandria to sort out the meaning of race, and didn't, quite.

DNA used to ascertain race of unidentified serial killer. Florida company DNAPrint Genomics claims their test can identify the race (ie, African, Caucasian, East Asian or American Indian) of a person from their DNA. CEO Tony Frudakis says that "of over 2,200 blind samples tested, the test is yet to get one wrong."

Seattle PI have picked up the news that there's now competition in the race to build a space elevator. Liftport are the new kids on the block, with a website that only went online about 24 hours ago. I'm watching them build the message board as I type. Nothing like a bit of uplifting science news (pun unavoidable).

White couple gets black twins, sue IVF clinic. Experts say a mistake could have occurred in one of three ways.The wrong sperm could have been used to fertilise the right egg, the right sperm could have been used to fertilise the wrong egg, or the embryo implanted in the woman may have been another couple's altogether. Although it is not clear whether another couple has laid claim to the children, legal experts say the judge will be expected to make a modern-day judgment of Solomon on who should be considered the babies' legal parents. This is unploughed legal ground. Is there a fair way to sort this out?

Race-based Science Project Banned Forgetting for a moment how flimsy the premise of science projects at the 5th grade age can be, I think this is a great project. Does anyone find this offensive? Should children be allowed to discuss race and racism in broad daylight and among their peers?
