Excluding Intelligent Design Principles From the Search For Alien Life 308

KIdPanda writes "Prompted by pictures of man-made structures in the Utah desert, a SETI astronomer explains the sometimes-ambiguous difference between seeing the hand of God, alien intelligence, or nature. 'In my photographs, Shostak's SETI-trained eye — standing in for a pattern-crunching computer program — searched for an unexpected increase in visual order (or, in thermodynamic terms, a decrease in entropy caused by the rebellion of life against universal decay). A road or a tended field is mathematically simpler than a mountainous jumble or naturally varied vegetation. ... But there's an obvious problem: nothing is simpler than a sweep of blue sky, or the inky blackness of space. If simplicity is the benchmark, space itself is evidence of design."

Untangling Web Information 76

Ostracus writes "The next big stage in the evolution of the Internet, according to many experts and luminaries, will be the advent of the Semantic Web — that is, technologies that let computers process the meaning of Web pages instead of simply downloading or serving them up blindly. Microsoft's acquisition of the semantic search engine Powerset earlier this year shows faith in this vision. But thus far, little Semantic Web technology has been available to the general public. That's why many eyes will be on Twine, a Web organizer based on semantic technology that launches publicly today."

Research Finds Carbon Dating Flawed 625

eldavojohn writes "New research funded by the National Science Foundation at the University of Miami is showing that carbon dating (the 13C/12C ratio used to infer age) in the ocean can only be trusted up to 150 million years ago. From the primary researcher, 'This study is a major step in terms of rethinking how geologists interpret variations in the 13C/12C ratio throughout Earth's history. If the approach does not work over the past 10 million years, then why would it work during older time periods? As a consequence of our findings, changes in 13C/12C records need to be reevaluated, conclusions regarding changes in the reservoirs of carbon will have to be reassessed, and some of the widely-held ideas regarding the elevation of CO2 during specific periods of the Earth's geological history will have to be adjusted.' While this research doesn't necessarily throw carbon dating out the window, it should cause people to rethink so many theories about early life that revolved around ages of sediment in the oceans."

Biologist (Almost) Creates Artificial Life 539

Aditya Malik writes "Wired has an interesting story up about how a lab led by Jack Szostak, a molecular biologist at Harvard Medical School, is building 'protocells' from artificial molecules which are very close to satisfying the conditions for being 'alive.' 'Szostak's protocells are built from fatty molecules that can trap bits of nucleic acids that contain the source code for replication. Combined with a process that harnesses external energy from the sun or chemical reactions, they could form a self-replicating, evolving system that satisfies the conditions of life, but isn't anything like life on earth now, but might represent life as it began or could exist elsewhere in the universe.' This obviously raises some questions about creationism, not to mention some scary bio-research-gone-wild scenarios."

Prions Observed Jumping Species Barrier 214

palegray.net writes "Nature is reporting on new findings that prions jump species barriers. Believed to be responsible for ailments such as Creutzfeld-Jakob disease and 'mad cow' disease, prions are thought to disrupt biological processes by causing normal proteins to fold abnormally. Researchers at the University of Texas Medical Branch in Galveston have observed infectious prions from hamsters causing abnormal protein development in mice, along with a range of other observations on prion actions in test tube environments. From the article: '... they also found that when a prion jumps species, it produces a new kind of prion. "This is very worrisome," says Claudio Soto, who led the research, published in Cell. "The universe of possible prions could be much larger than we thought."' Sounds like another good reason to donate your spare CPU cycles to projects like Folding@home."

Opposable Thumbs and Upright Walking Caused By "Junk DNA" 215

quinnlynn writes "A group of research scientists at Yale discovered that the evolution of opposable thumbs and upright walking in humans is due to changes in the genome in the areas still classified as "junk DNA." Quoting: 'Results from a comparative analysis of the human, chimpanzee, rhesus macaque and other genomes reported in the journal Science suggest our evolution may have been driven not only by sequence changes in genes, but by changes in areas of the genome once thought of as "junk DNA." ... Researchers have long suspected changes in gene expression contributed to human evolution, but this had been difficult to study until recently because most of the sequences that control genes had not been identified. In the last several years, scientists have discovered that non-coding regions of the genome, far from being junk, contain thousands of regulatory elements that act as genetic "switches" to turn genes on or off.'" Yale has also recently completed sequencing the Trichoplax genome. Trichoplax has the simplest known animal genome, and it shares 80 percent of its genes (comprised of 98 million base pairs) with humanity. Professor Stephen Dellaporta was quoted saying, "We are [excited] to find that Trichoplax contains shared pathways and defined regulatory sequences that link these most primitive ancestors to higher animal species. The Trichoplax genome will serve as a type of 'Rosetta Stone' for understanding the origins of animal-specific pathways."

New Evidence Debunks "Stupid" Neanderthal 505

ThinkComp writes "In what could possibly be a major blow to a scientific consensus that has held for decades, recent research suggests that the traditional conception of Neanderthals being "stupider" than Homo sapiens may in fact be misleading. As articles about the research findings state, 'early stone tool technologies developed by our species, Homo sapiens, were no more efficient than those used by Neanderthals.' The data used in the study is available on-line along with a visual description of the process used."

Cooking Stimulated Big Leap In Human Cognition 473

Hugh Pickens writes "For a long time, humans were pretty dumb, doing little but make 'the same very boring stone tools for almost 2 million years,' says Philipp Khaitovich of the Partner Institute for Computational Biology in Shanghai. Then, 150,000 years ago, our big brains suddenly got smart. We started innovating. We tried different materials. We started creating art and maybe even religion. To understand what caused the cognitive spurt, researchers examined chemical brain processes known to have changed in the past 200,000 years. Comparing apes and humans, they found the most robust differences were for processes involved in energy metabolism. The finding suggests that increased access to calories spurred our cognitive advances, although definitive claims of causation are premature. In most animals, the gut needs a lot of energy to grind out nourishment from food sources. But cooking, by breaking down fibers and making nutrients more readily available, is a way of processing food outside the body. Eating (mostly) cooked meals would have lessened the energy needs of our digestion systems, thereby freeing up calories for our brains. Today, humans have relatively small digestive systems and allocate around 20% of their total energy to the brain, compared to approximately 13% for non-human primates and 2-8% for other vertebrates. While other theories for the brain's cognitive spurt have not been ruled out, the finding sheds light on what made us, as Khaitovich put it, 'so strange compared to other animals.'"

Ohio Sues Over Missing Electronic Votes 341

dstates writes "The Columbus Post Dispatch reports that the State of Ohio is suing Premier Election Systems (previously known as Diebold) over malfunctions in electronic voting machines. Election workers found that votes were 'dropped' in at least 11 counties when memory cards were uploaded to computer servers. The same voting machines are used nationwide. The company blames a conflict between their software and antivirus software for the problem and says that an advisory was issued on the subject. The Ohio lawsuit contends that the company made false representations and failed to live up to contractual obligations and seeks punitive damages."

How To Show Code Samples? 485

Todd writes "I've been looking around at 'help wanted' advertisements for programming jobs, and almost all of them demand that you not only have professional experience, but also that you show samples of your work. This got me wondering; with the work product, trade secret, and non-disclosure laws/agreements, how exactly can you show work that you've done in a professional capacity to a prospective employer without violating the privacy of the company for which the code was written? For instance, I can't say I've written many BASH scripts (at least, not large ones) for myself personally, but the assortment of such scripts written for my current job is wide and varied indeed. I can't very well just deliver these scripts, or even small portions thereof, to third parties to help demonstrate my scripting prowess. With that in mind, what am I supposed to show them?"

eBay'er Arrested For Attempting To Sell His Vote 501

The Associated Press reports that Max P. Sanders, 19, is charged with a felony for attempting to auction off his vote on eBay for the upcoming presidential election. From the article: '"Fundamentally, we believe it is wrong to sell your vote," said John Aiken, a spokesman for the office. "There are people that have died for this country for our right to vote, and to take something that lightly, to say, 'I can be bought... It's a real shame"' Yes, that is a terrible shame, isn't it. Perhaps we should arrest, prosecute, and imprison everyone who sells their vote. The boy says it was all a joke, but prosecutors aren't laughing. Max faces up to 5 years in prison and $10,000 in fines if he is convicted.

Higher Oil Prices Are Starting To Bring Jobs Home 777

penguin_dance notes a report up at ABC News that high oil and gas prices in the US may be moving jobs back home in a trend that some economists are calling "reverse globalization." It's becoming more and more expensive to ship finished product from other countries, so some companies are moving the manufacturing back to the US. The article hints that this trend may spill over soon to raw materials such as steel. One economist is quoted: "It's not just about labor costs anymore. Distance costs money, and when you have to shift iron ore from Brazil to China and then ship it back to Pittsburgh, Pittsburgh is looking pretty good at 40 bucks an hour."

Bacteria Make Major Evolutionary Shift In the Lab 1185

Auxbuss sends us to New Scientist for news sure to perplex and confound creationists: scientists have watched a new, complex evolutionary trait develop in the lab. "A major evolutionary innovation has unfurled right in front of researchers' eyes. It's the first time evolution has been caught in the act of making such a rare and complex new trait. And because the species in question is a bacterium, scientists have been able to replay history to show how this evolutionary novelty grew from the accumulation of unpredictable, chance events."

Ben Stein's 'Expelled' - Evolution, Academia and Conformity 1766

eldavojohn writes "Painting the current scientific community as just as bad as the Spanish Inquisition, an extended trailer of Ben Stein's "Expelled" has a lot of people (at least that I know) talking. It looks like his movie plans to encourage people to speak out if they believe intelligent design or creationism to be correct. In the trailer he even warns you that if you are a scientist you may lose your job by watching 'Expelled.' Backlash to the movie has started popping up and this may force the creationism/evolutionist debate to a whole new level across the big screen and the internet." adholden points out a site called Expelled Exposed, which asserts that 'Expelled' "is simply an anti-science propaganda film aimed at creating controversy where none exists, while promoting poor science education that can and will severely handicap American students."
