Submission + - Moebius strip riddle solved at last (abc.net.au) 2

BigLug writes: "In a study to appear in Nature Materials, two experts in non-linear dynamics, Gert van der Heijden and Eugene Starostin of University College London, resolve the Moebius Strip algebraically.

From the ABC (Australia):



What determines the strip's shape is its differing areas of "energy density," they say.

"Energy density" means the stored, elastic energy that is contained in the strip as a result of the folding. Places where the strip is most bent have the highest energy density; conversely, places that are flat and unstressed by a fold have the least energy density.

Submission + - The Computer Virus Turns 25 in July 1

bl8n8r writes: In July of 1982, an infected Apple II propogated the first computer virus onto a 5-1/4" floppy. The virus, which did little more than annoy the user, Elk Cloner, was authored in Pittsburgh by a 15-year-old high school student, Rich Skrenta. The virus replicated by monitoring floppy disk activity and writing itself to the floppy when it was accessed. Skrenta describes the virus as "It was a practical joke combined with a hack. A wonderful hack." Remember, he was a 9th grader when he did this.

Firefox Now Serious Threat to IE in Europe 384

Tookis writes "Mozilla's Firefox web browser has made dramatic gains on Microsoft's Internet Explorer throughout Europe in the past year with a marked upturn in FF use compared to IE over the past four months, according to French web monitoring service XiTiMonitor. A study of nearly 96,000 websites carried out during the week of July 2 to July 8 found that FF had 27.8% market share across Eastern and Western Europe, IE had 66.5%, with other browsers including Safari and Opera making up the remaining 5.7%. In some key European markets FF has already reached parity and is threatening to overtake IE as the market leading browser."

Fructose As Culprit In the Obesity Epidemic 821

drewtheman writes "According to an interview with Dr. Robert Lustig, Professor of Pediatric Endocrinology from the University of California, San Francisco, fructose, once touted as diabetic-friendly because it doesn't raise insulin levels directly, could be a major culprit for the obesity epidemic, high blood pressure, and elevated blood levels of LDL in Americans and others worldwide as they adopt American-style diets. Fructose comprises 50% of table sugar and up to 90% of high-fructose corn syrup, both ingredients found in copious quantity in most American prepared foods."

Dark Energy May Lurk In Hidden Dimensions 164

Magdalene writes in to let us know about a sketch of an idea, that might one day become a theory, to explain the dark energy that is making the universe flee faster and faster apart. It posits that dark energy may be the result of a new kind of neutrino wandering in tiny extra dimensions above our familiar three. She adds, "There is no word yet on whether Sphere or Square are available for comment." From the article: "The mysterious cosmic presence called dark energy, which is accelerating the expansion of the universe, might be lurking in hidden dimensions of space. This idea would explain how the dimensions of space remain stable — one of the biggest problems for the unified scheme of physics called 'string theory'... To get the same amount of acceleration seen by astronomers, Greene and Levin calculate that the extra dimensions should have a scale of about 0.01 millimeter."
