Iddo Genuth writes "Researchers at the Massachusetts Institute of Technology Department of Aeronautics and Astronautics recently won a contract from the National Aeronautics and Space Administration to design quieter, more energy efficient, and more environmentally friendly commercial airplanes. The two-million-dollar contract from NASA is just an initial step in bringing green technologies to the sky."

mernil sends in an article from the NYTimes that casts a glance at a study done in the Czech Republic (natch) on what divides the successful scientists from the duffers. "Ever since there have been scientists, there have been those who are wildly successful, publishing one well-received paper after another, and those who are not. And since nearly the same time, there have been scholars arguing over what makes the difference. What is it that turns one scientist into more of a Darwin and another into more of a dud? After years of argument over the roles of factors like genius, sex, and dumb luck, a new study shows that something entirely unexpected and considerably sudsier may be at play in determining the success or failure of scientists — beer."

An anonymous reader writes "Convinced the current music business infrastructure (requiring artists to rely on labels) is broken, Nine Inch Nails front man, Trent Reznor, released his band's new album, Ghosts I — IV (Ghosts Volumes One though Four), on Sunday at 6 PM via his official site, marking yet another business experiment for this artist in the changing music market."

The Narrative Fallacy brings news that NASA has awarded a $500,000 grant to develop plans for an array of radio telescopes to be located on the moon. The telescopes would be used to gather data from the earliest stars and galaxies, observations of which are difficult from Earth due to the ionosphere and terrestrial broadcasts. The grant was part of NASA's sponsoring of 19 "Next Generation Astronomy Missions." Quoting: "The Lunar Array for Radio Cosmology (LARC) project ... is planned as a huge array of hundreds of telescope modules designed to pick up very-low-frequency radio emissions. The array will cover an area of up to two square kilometers; the modules would be moved into place on the lunar surface by automated vehicles. The new lunar telescopes would add greatly to the capabilities of a low-frequency radio telescope array now under construction in Western Australia, one of the most radio-quiet areas on Earth."

6 writes to let us know that two optical researchers have proposed, as a thought experiment, a novel idea for solving the traveling salesman problem. From the abstract: We introduce an optical method based on white light interferometry in order to solve the well-known NP-complete traveling salesman problem. To our knowledge it is the first time that a method for the reduction of non-polynomial time to quadratic time has been proposed. We will show that this achievement is limited by the number of available photons for solving the problem. It will turn out that this number of photons is proportional to N^N for a traveling salesman problem with N cities and that for large numbers of cities the method in practice therefore is limited by the signal-to-noise ratio. The proposed method is meant purely as a gedankenexperiment."
