EO Wilson believes in Darwinism group selection: "evolution as a multi-level process1 that can evolve adaptations above the level of individual organisms."

Correlative Analytics -- or as O'Reilly might term the Social Graph -- sort of mirrors the debate on 'brute force' algorithmic proofs (that are "true for no reason," cf.) in which "computers can extract patterns in this ocean of data that no human could ever possibly detect. These patterns are correlations. They may or may not be causative, but we can learn new things. Therefore they accomplish what science does, although not in the traditional manner... In this part of science, we may get answers that work, but which we don't understand. Is this partial understanding? Or a different kind of understanding?" Of course, say some in the scientific community: hogwash; it's just a fabrication of scientifically/statistically illiterate pundits, like whilst new techniques in data analysis are being developed to help keep ahead of the deluge...

Andy Grove on Our Electric Future - "Energy independence [viz.] is the wrong goal. Here is a plan Americans can stick to." Perhaps some infrastructure spending1,2 is in order? [etc., &c., cf.]

Dean Kamen's Artificial "Luke" Arm - Segway inventor reinvents the prosthetic arm: "I've been able to do stuff with this that I haven't, seriously haven't, done in 26 years... uh, pick up a banana, peel a banana and eat it without it squishening... I can't wait to get one of these in a real environment, a home environment, and actually my wife can't either. She's going, oh yeah, I got lots of stuff for you to do."

'Race' graphically illustrated - "most Europeans" vs. Ashkenazim (previously; see also IQ & Gladwell, viz. ;)

The dangers of living in a zero-sum world economy - naked capitalism reprints (with added commentary) an FT article by Martin Wolf on why it's vital for (civilised) society to sustain a 'positive-sum' world, otherwise: "A zero-sum economy leads, inevitably, to repression at home and plunder abroad." Wolf's solution? "The condition for success is successful investment in human ingenuity." Of course! Some are calling for more socialism, while others would press on to build more megaprojects. For me, at least part of the solution lies in environmental accounting and natural capitalism :P

Good evidence that dark matter is for real.

A NOAA report says Earth's surface and atmosphere are both warming, and that earlier work that found otherwise contains flaws. In other news, global warming has started to weaken an important wind circulation pattern over the Pacific Ocean, a study suggests. The change could alter climate and the marine food chain in that area; polar bears and walrus pups sad.

Before the Big Bang - way, way out of my depth, but I thought this comment was intriguing: "The paper as published, along with a longer follow up paper, looks to my untrained eye a nearly complete quantum gravitation theory, which is an exciting prospect in itself. However, as with all physical theories, we will await for experimental support before popping the cork." Here's some more on loop quantum gravity, spin networks, the big bang and ekpyrosis.

Know less than nothing!? What could negative knowledge possibly mean? In short, after I tell you negative information, you will know less... "In this week's issue of Nature, however, Michal Horodecki and colleagues present a fresh approach to understanding quantum phenomena that cannot be grasped simply by considering their classical counterparts." [via slashdot :]

The Logic of Diversity "A new book, The Wisdom of Crowds [..:] by The New Yorker columnist James Surowiecki, has recently popularized the idea that groups can, in some ways, be smarter than their members, which is superficially similar to Page's results. While Surowiecki gives many examples of what one might call collective cognition, where groups out-perform isolated individuals, he really has only one explanation for this phenomenon, based on one of his examples: jelly beans [...] averaging together many independent, unbiased guesses gives a result that is probably closer to the truth than any one guess. While true — it's the central limit theorem of statistics — it's far from being the only way in which diversity can be beneficial in problem solving." (Three-Toed Sloth)

Female X chromosome 'cracked' - "The discovery, by an international consortium of scientists, shows that females are far more variable than previously thought and, when it comes to genes, more complex than men." Nature reports two new studies; one on the complete sequencing of the X chromosome for humans, which sheds some light on how sex evolved and how women differ from men, and another on how women express many genes from X chromosomes previously thought dormant.

Jaron Lanier talks about philosophy, computer science and physics. Suppose poor old Shroedinger's Cat has survived all the quantum observation experiments but still has a taste for more brushes with death. We could oblige it by attaching the cat-killing box to our camera. So long as the camera can recognize an apple in front of it, the cat lives.

Laser Weapons like in Real Genius, but for real! Combine them with GPS and you get Death Rays!! The technology is there, but how will it change warfare? (via drudge :)

Reading through Physics Today (as I'm wont to do on occasion) I came across this absolutely enthralling article on Wolfgang Pauli of whom I've never heard. Truly an admirable specimen among Physicus Intellectus. Also, it behooves me to mention "A Remembrance of Pauli in 1950."
