News for nerds, stuff that matters Mon, 13 Oct 2008 10:58:00 +0200 fatalfury writes "Researchers from the University of Vienna asked 20 males and 20 females to rank vehicles based on their appearance. The list of traits included arrogant, afraid, agreeable, disgusted, extroverted, sad, and others. Cars with 'meaner' traits (such as BMW) ranked higher, whereas cars with 'nicer' traits (such as Toyota's Prius) ranked lower. With billions spent on developing new products in the automobile industry, this could spur a trend in meaner-looking cars and perhaps explain why sales of the Prius and other green cars are slow to take off with average consumers."

To accommodate the extra '1,' the clock was hacked: the '1' from "$10.2" has been moved left to the LCD square once occupied solely by the digital dollar sign. A non-digital, improvised dollar sign has been pasted next to the '1.' It will be replaced in 2009 with a new clock able to track debt up to a quadrillion dollars, which is a '1' followed by 15 zeros. That should be good enough for a few more months at least, I believe." Adds reader MarkusQ, "I know Dick Cheney has assured us that 'Deficits don't matter' but I can't help wondering if we should be fixing the problem rather than the sign."

Sun, 12 Oct 2008 22:30:00 +0200 FiReaNGeL writes "Researchers conducted a genome-wide association study of 1,125 Caucasian men who had been assessed for male pattern baldness. They found two previously unknown genetic variants on chromosome 20 that substantially increased the risk of male pattern baldness. They then confirmed these findings in an additional 1,650 Caucasian men. 'If you have both the risk variants we discovered on chromosome 20 and the unrelated known variant on the X chromosome, your risk of becoming bald increases sevenfold. What's startling is that one in seven men have both of those risk variants.'" So maybe gene therapy will finally have a real purpose.

The Soyuz capsule will dock to the ISS in two days. Garriott will return to Earth with Expedition 17 crew members, Commander Sergei Volkov and Flight Engineer Oleg Kononenko on October 23." With the extra attention on this launch, the Russians have gone out of their way to say that the return of the Soyuz vehicle will be safe, after a couple of different malfunctions in the past year. Garriott is in space partly for recreation, and partly as a promotion for his latest MMO, Tabula Rasa. He took with him a hard drive filled with information about humanity, as well as DNA sequences from Tabula Rasa players and various celebrities (including Stephen Colbert and Stephen Hawking) to 'preserve' that data in case of a disaster on Earth. Garriott will also spend time running and participating in experiments. Coverage of the Soyuz mission is ongoing at NASATV.

It's not much of a stretch to imagine that all of that imaginary wealth is locked up somewhere inside the computers, and that we humans, led by the silverback males of the financial world, Ben Bernanke and Henry Paulson, are frantically beseeching the monolith for answers.'" The quoted essay from George Dyson is available at Edge.

After a tumor is located on an MRI, the robot will perform a biopsy of the breast while the patient is inside the scanner. 'If the biopsy displays cancerous cells, the robot will then insert a probe into the breast until it reaches the tumor. The probe will then burn the cancer cells until they are destroyed.' This looks great, but the researchers have only built a prototype. After they refine this robot, they'll need to go through clinical trials and obtain FDA approval. So this is not a robot that will appear on the medical market before several years."

He founded the Loebner prize in 1990 to promote the development of artificial intelligence by asking developers to create a machine which passes the Turing Test — meaning it responds in a way indistinguishable from a human. The latest running of the contest is this weekend and this article shows what an interesting and colourful character Loebner is."

She recently announced that she will be heading to Moscow to train as backup astronaut for Charles Simonyi, who plans to fly aboard Soyuz TMA-14 next year. The US$3 million price tag won't be her first cash contribution towards personal space flight. She's already an investor in Space Adventures, the company that arranges the space tourist flights on Soyuz."

While we've been able to locate a few "super earths" so far, none of them really compare in size or the potential for habitability with our own world. Fortunately, advances in data analysis and new space-based telescopes — such as Kepler, the James Webb Space Telescope, and the already-launched CoRoT (PDF) — have some astronomers predicting we'll find such an exoplanet by 2010, and a habitable one by 2012. Earth-based telescopes are also in the hunt, though the article notes, "even if a habitable Earth-like world is found first from the ground, it will most likely take a space observatory to search for the chemical signals that tell us what we really want to know: Is anything living out there? If the planet is one that can be observed transiting, it just might be possible to provide a hint of an answer in the next few years."

'The discovery of 525-million-year-old fossils belonging to a new species of arthropod shows that these animals formed communal chains never before seen in fossilized invertebrates.' It should be obvious to any Slashdotter of a certain age that this is the true origin of the so called 'centipede' in the eponymous game."

The New York Times reports on a recent study that shows the US fails to encourage academic talent as a culture.'"There is something about the culture in American society today which doesn't really seem to encourage men or women in mathematics," said Michael Sipser, the head of M.I.T.'s math department. "Sports achievement gets lots of coverage in the media. Academic achievement gets almost none."' While we've suspected that the US might be falling behind academically, this study shows that it is actually due to cultural factors that are devaluing the success of our students. I suspect there's a flaw in the US cultural system that prevents achievement on the academic front from being perceived as valuable. Could anyone suggest a patch for this bug or is this cause for a rewrite?"

Fri, 10 Oct 2008 00:48:00 +0200 caffeinemessiah writes "The New York Times has an interesting story on a new algorithm by researchers from Tel Aviv University that modifies a facial picture of a person to conform to standards of attractiveness. Based on a digital library of pictures of people who have been judged 'attractive,' the algorithm finds the nearest match and modifies an input picture so it conforms to the 'attractive' person's proportions. The trick, however, is that the resultant pictures are still recognizable as the original person. Here's a quick link to a representative picture of the process. Note that this is a machine-learning approach to picture modification, not a characterization of beauty, and could just as easily be used to make a person less attractive." Note: As reader Trent Waddington points out, the underlying research was mentioned in an earlier story as well.

This is the first time in history that the whole planet is going to be photographed in its entirety by an Earthling probe, with amazing resolution and ultra-crisp detail." The picture at the top of the linked story is fantastic, too.

'It's so simple,' says Ermanno F. Borra, physics professor at the Optics Laboratory of Laval University in Quebec, Canada. 'Isaac Newton knew that any liquid, if put into a shallow container and set spinning, naturally assumes a parabolic shape, the same shape needed by a telescope mirror to bring starlight to a focus. This could be the key to making a giant lunar observatory.'"

He asserts that human beings have stopped evolving because modern social customs have lowered the age at which human males have offspring, which results in fewer of the mutations necessary to drive evolutionary change. Apparently the fate of our species now depends upon older guys hooking up with younger woman. I, for one, welcome this development."
