Cars could run on recycled newspaper, scientists say (August 26, 2011) -- Here's one way that old-fashioned newsprint beats the Internet. Scientists have discovered a novel bacterial strain, dubbed "TU-103," that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline. They are currently experimenting with old editions of the Times Picayune, New Orleans' venerable daily newspaper, with great success. ... > full story

Feeding the five thousand -- or was it three? Researchers claim most crowd estimations are unreliable (August 26, 2011) -- The public should view crowd estimation with skepticism, say the authors of a new study, as they suggest more reliable alternatives to current estimating methods. ... > full story

Exotic galaxy reveals tantalizing tale (August 26, 2011) -- A galaxy with a combination of characteristics never seen before is giving astronomers a tantalizing peek at processes they believe played key roles in the growth of galaxies and clusters of galaxies early in the history of the Universe. The galaxy, dubbed Speca by the team of researchers, is only the second spiral, as opposed to elliptical, galaxy known to produce large, powerful jets of subatomic particles moving at nearly the speed of light. It also is one of only two galaxies to show that such activity occurred in three separate episodes. ... > full story

Uncovering the spread of deadly cancer: New imaging device enables scientists to see tumor cells traveling in the brain (August 26, 2011) -- For the first time, scientists can see pathways to stop a deadly brain cancer in its tracks. Researchers have imaged individual cancer cells and the routes they travel as the tumor spreads. ... > full story

New depiction of light could boost telecommunications channels (August 26, 2011) -- Physicists have presented a new way to map spiraling light that could help harness untapped data channels in optical fibers. Increased bandwidth would ease the burden on fiber-optic telecommunications networks taxed by an ever-growing demand for audio, video and digital media. The new model could even spur enhancements in quantum computing and other applications. ... > full story

New X-ray technique for electronic structures: Ability to probe deep below material surfaces should be boon for nanoscale devices (August 26, 2011) -- Researchers have led the development of a technique called HARPES, for Hard X-ray Angle-Resolved PhotoEmission Spectroscopy, that enables the study of electronic structures deep below material surfaces, including the buried layers and interfaces in nanoscale devices. This could pave the way for smaller logic elements in electronics, novel memory architectures in spintronics, and more efficient energy conversion in photovoltaic cells. ... > full story

Mathematical model predicts weight with varying diet, exercise changes; Findings challenge one-size-fits-all weight assumptions (August 26, 2011) -- Researchers have created a mathematical model -- and an accompanying online weight simulation tool -- of what happens when people of varying weights, diets and exercise habits try to change their weight. The findings challenge the commonly held belief that eating 3,500 fewer calories -- or burning them off exercising -- will always result in a pound of weight loss. ... > full story

Earth-bound asteroids come from stony asteroids, new studies confirm (August 26, 2011) -- Researchers got their first up-close look at dust from the surface of a small, stony asteroid after the Hayabusa spacecraft scooped some up and brought it back to Earth. Analysis of these dust particles confirms a long-standing suspicion: that the most common meteorites found here on Earth, known as ordinary chondrites, are born from these stony, or S-type, asteroids. ... > full story

Build music with blocks: Audio d-touch (August 26, 2011) -- Researchers have developed a new way to generate music and control computers. ... > full story

Milky Way's halo raining ionized gas to fuel continued star formation (August 26, 2011) -- Astrophysicists have concluded that the Milky Way will have the fuel to continue forming stars, thanks to massive clouds of ionized gas raining down from its halo and intergalactic space. The Milky Way would rapidly change its gas into stars if no supply of new matter were available to replenish the gas. ... > full story

Using math to fight cancer (August 26, 2011) -- Researchers have developed a mathematical model to understand and predict the progress of a tumor, from its early stages to metastasis, in hopes of creating highly personalized treatment strategies for patients who have cancer. ... > full story

Simple way to grow muscle tissue with real muscle structure (August 26, 2011) -- Researchers have found a simple way to grow muscle tissue with a real muscle structure in the laboratory. They found that the muscle cells automatically align themselves if they are subjected to tension in one direction -- this is essential for the ability of the muscle cells to exert a force. ... > full story
