An anonymous reader writes "Most of us have heard of string theory, many of us know what it is and some of us may even be experts in the field. But could you explain it in two minutes? Discover Magazine recently had a contest to do precisely that: create a two minute or less video of everything you need to know about string theory. You can view some of the best entries (video) as well as the winning video: String Ducky!"Read more of this storyat Slashdot.

  swordgeek writes "Comet 17P/Holmes, a relatively obscure and (until a few days ago) dim object, has suddenly flared to be literally a million times brighter, going from magnitude 18 to 2.8. It is just outside of the constellation Perseus, which puts it high in the sky and ideal for viewing at this time of year. The comet still appears starlike even in binoculars but should grow to several arcminutes across over the next few nights. The comet is now readily visible to the naked eye. This is a completely unexpected once-in-a-lifetime event, so get out your finest optics (even if it's just your eyes) and go comet watching!"Read more of this storyat Slashdot.

  The Technology Review site has up an article on new software that can do quantitative analysis of facial expressions, detecting whether a person is smiling. The software was developed by the Omron Corporation, and can also estimate a subject's age and gender, or verify a person's identity from a database. Though the company doesn't yet know whether it plans to release the software commercially, there are a number of obvious applications. "Omron envisions the smile software being used in marketing, perhaps to evaluate consumers' reactions to a new product or to an advertising campaign. A smile checker could also help train customer-service staff to meet Japan's legendarily high standards ... A smile in isolation is easy to detect, but the bigger challenge is to develop systems that can recognize the concerto of facial actions that make up complex expressions like confusion, fear, and disgust."

The pandemic paper planning scenario is used by 3,000 banks, insurance companies and security firms in preparing for disasters.

  i_like_spam writes "The New York Times has up a story about a paper published in 1955 by Homer Jacobson, a chemistry professor at Brooklyn College. The paper, entitled 'Information, Reproduction and the Origin of Life', speculated on the chemical qualities of earth in the Hadean time, billions of years ago when the planet was beginning to cool down to the point where, as Dr. Jacobson put it, 'one could imagine a few hardy compounds could survive.' Nobody paid much attention to the paper at the time, but today it is winning Dr. Jacobson acclaim that he does not want — from creationists who cite it as proof that life could not have emerged on earth without divine intervention. So after 52 years, he has retracted the paper. 'Dr. Jacobson's retraction is in "the noblest tradition of science," Rosalind Reid, editor of American Scientist, wrote in its November-December issue, which has Dr. Jacobson's letter. His letter shows, Ms. Reid wrote, "the distinction between a scientist who cannot let error stand, no matter the embarrassment of public correction," and people who "cling to dogma."'"Read more of this storyat Slashdot.

  eldavojohn writes "Hundreds of black holes that were thought to exist at the beginning of the universe have been found by NASA's Spitzer and Chandra space telescopes. From the article, 'The findings are also the first direct evidence that most, if not all, massive galaxies in the distant universe spent their youths building monstrous black holes at their cores. For decades, a large population of active black holes has been considered missing. These highly energetic structures belong to a class of black holes called quasars. A quasar consists of a doughnut-shaped cloud of gas and dust that surrounds and feeds a budding supermassive black hole. As the gas and dust are devoured by the black hole, they heat up and shoot out X-rays. Those X-rays can be detected as a general glow in space, but often the quasars themselves can't be seen directly because dust and gas blocks them from our view.' This is pretty big, as it's empirical evidence proving the existence of objects that theoretically had to exist but could not be detected previously."Read more of this storyat Slashdot.

  Ian Lamont writes "You probably remember reading about Brian May getting a PhD in Astrophysics, but may not know about the many other celebrities from the music, TV, and film worlds who have studied science and technology in college and grad school, or are simply serious gearheads who like gadgets, games, and other geek pastimes. Computerworld has identified about 50 celebrities who fit the bill, including Dan Grimaldi (Patsy Parisi, The Sopranos) who has a Bachelor of Arts degree in math, a master's in operations research and a Ph.D. in data processing; Rowan Atkinson, who has a master's in electrical engineering from Queen's College, Oxford; and Todd Rundgren, who developed an early paint program called Utopia.

According to a new report, US schools are turning out more capable science and engineering grads than the job market can support. 'The authors of the report, the Urban Institute's Hal Salzman and Georgetown University professor Lindsay Lowell, show that math, science, and reading test scores at the primary and secondary level have increased over the past two decades, and U.S. students are now close to the top of international rankings. Perhaps just as surprising, the report finds that our education system actually produces more science and engineering graduates than the market demands.'"Read more of this storyat Slashdot.

  Identity Missing writes "Lockheed Martin is planning on building a commercial spaceport in Nova Scotia Canada. The details are a bit shaky, but apparently the project is serious enough to attract 45 million dollars from the Federal government. The launch pad will specifically be built in Cape Breton, a mostly rural island characterized by low employment, thick colloquial accents, and kitchen fiddle parties.

  ackthpt writes "Ikhana (a NASA drone) is primarily designed for suborbital earth sciences missions, but may be fitted out with a variety of sensors. Wednesday, Ikhana took off from Edwards Air Force Base for a 10 hour mission to observe forest fires in California, scanning the terrain from 23-25,000 feet using a variety of sensors for visible and IR light. Able to remain aloft for up to 30 continuous hours Ikhana serves up information in minutes, a process that takes hours when done by manned aircraft observation. 'The data is processed on the aircraft, up-linked to a satellite and then downloaded to a ground station. From there it's delivered to a computer server at NASA Ames. The imagery is then combined with Google Earth maps. Command center personnel can view the images on their computer screens and then delegate local firefighters accordingly.'"Read more of this storyat Slashdot.

While many researchers are looking for new drugs to combat the disease, those efforts could take years to bear fruit. Meanwhile, two scientists at the Albert Einstein College of Medicine have learned how the drug clavulanate can destroy the defenses of tuberculosis, making it vulnerable to medications in the penicillin family. The best part: it has already been approved by the FDA so doctors can start using it immediately."Read more of this storyat Slashdot.

  Henning Burdack writes "Eric Lerner talks on Google Tech Talks about Focus Fusion, which would be a much cheaper and more feasible technology as a fusion energy source than any other current approach, based upon the dense plasma focus device. The technology will use hydrogen-boron fusion with direct induction of ion energy and photovoltaic conversion of x-ray emission, obviating the need of a steam-cycle and thus resulting in higher efficiencies. High temperatures of 1 billion Kelvin (100 keV) have been reached years ago. It only needs $2 million in funding and two years of research for a proof of concept, and maybe four more years for a prototype with positive energy output. In contrast to other fusion efforts it utilizes the natural instabilities of plasma instead of fighting them. Focus Fusion has been discussed on Slashdot before, and a patent application is also available, going a bit more into detail."Read more of this storyat Slashdot.
