Submission + - Ebay Mulling Skype Sale (ft.com)

MaineCoasts writes: The Financial Times reports that Ebay's new CEO is evaluating a sale of Skype if new ways cannot be found for the fast-growing service to support its core e-commerce business. Ebay reported earlier this week that Skype had a 61 percent increase in first quarter revenue over the same quarter last year and now has 309 million users worldwide.

Feed Techdirt: Has Congress Backdoored In 'Attempted Copyright Infringement' As A Crime? (techdirt.com)

Last year, when Alberto Gonzales was under pressure from Congress, he suddenly started spending a lot of time talking about stricter copyright laws. Perhaps it gave him a distraction from repeating "I do not recall" all day in front of Congress. His proposal was basically a laundry list of the entertainment industry's desired changes to copyright law, including making "attempted infringement" a crime. Despite the fact that copyright law is pretty clear that an actual violation needs to happen first, this would shift the standard so that if you just attempted to infringe, you could be found guilty of the full infringement itself. While Gonzales' efforts went nowhere, William Patry is pointing out that Congress may have backdoored in this "attempted" clause late last year through the Orwellianly-titled Criminal Code Modernization and Simplification Act. In that act, it notes that: "Unless otherwise provided by law, whoever attempts to commit an offense shall be punished as is provided for the completed offense." When it comes to copyright law in the bill, no exception is provided. Patry points to the recent story of the guy sent to jail for just clicking a link to give you a suggestion of where this new law will allow complaints to go. It's not a pretty picture.

Submission + - Mathematics (haaretz.com)

ArieKremen writes: A Russian immigrant mathematician-turned-nightwatchman-turned-mathematician has solved the Road Coloring problem, first posed in 1970 by Benjamin Weiss Roy Adler. The problem states that given a finite number of roads, one should be able to draw up a map, coded in various colors, that would lead to a certain destination regardless of the point of origin. The elusive problem remained unsolved for 38 years, until the immigrant mathematician Avraham Trakhtman found the solution. The problem has real-world implementation in message and traffic routing.

Submission + - Submersible glider powered by thermal changes

An anonymous reader writes: The torpedo-shaped glider moves through the ocean by changing its buoyancy to dive and surface, unlike motorized, propeller-driven undersea vehicles. To power its propulsion, the submersible gathers thermal energy from the ocean. When it moves from cooler water to warmer areas, internal tubes of wax are heated up and expand, pushing out the gas in surrounding tanks and increasing its pressure. The compressed gas stores potential energy, like a squeezed spring, that can be used to power the vehicle. To rise, oil is pushed from inside the vehicle to external bladders, thus increasing the glider's volume without changing its mass, making it less dense. The oil can be shifted inside to increase the density and sink the vehicle. A vertical tail rudder allows the glider to be steered horizontally. "This glider allows longer missions than previous [battery-run] versions," said Ben Hodges, a physical oceanographer at WHOI. "It could be out there for a year or two years. None of the old ones could go beyond six months. And producing fewer batteries is good for the environment."

Feed Science Daily: Deep Brain Stimulation In Hypothalamus Triggers Déjà Vu In Patient (sciencedaily.com)

A new study found that hypothalamic Deep Brain Stimulation performed in the treatment of a patient with morbid obesity unexpectedly evoked detailed autobiographical memories. While they were identifying potential appetite suppressant sites in the hypothalamus by stimulating electrode contacts that had been implanted there, the patient suddenly experienced a feeling of "déjà vu." As the intensity of the stimulation was increased, the details became more vivid. These sensations were reproduced when the stimulation was performed in a double-blinded manner.

Did Insects Kill the Dinosaurs? 184

Ponca City, We Love You writes "Asteroid impacts, massive volcanic flows, and now biting, disease-carrying insects have been put forward as an important contributor to the demise of the dinosaurs. In the Late Cretaceous the world was covered with warm-temperate to tropical areas that swarmed with blood-sucking insects. A theory explored by researchers at Oregon State suggests these bugs carried leishmania, malaria, intestinal parasites, arboviruses and other pathogens. Repeated epidemics may have slowly-but-surely worn down dinosaur populations while ticks, mites, lice and biting flies tormented and weakened them. 'After many millions of years of evolution, mammals, birds and reptiles have evolved some resistance to these diseases,' says Researcher George Poinar. 'But back in the Cretaceous, these diseases were new and invasive, and vertebrates had little or no natural or acquired immunity to them.' The confluence of new insect-spread diseases, loss of traditional food sources, and competition for plants by insect pests could all have provided a lingering, debilitating condition that dinosaurs were ultimately unable to overcome."
