    +Astronauts Hooks Up Harmony in Lengthy Spacewalk
      Tech.Luver writes "Astronauts spent seven hours in space to finish preparing the International Space Station for its next addition — Europe's first permanent space laboratory, the Columbus laboratory — which is sitting in the cargo bay of space shuttle Atlantis at Cape Canaveral, Florida launch pad — set to lift off on December 6."Read more of this storyat Slashdot.

    +Creationists Violating Copyright
      The_Rook writes "The Discovery Institute, more a lawyer mill than a scientific institution, copied Harvard University's BioVisions video 'The Inner Life of the Cell,' stripped out Harvard's copyright notice, credits, and narration, inserted their own creationist-friendly narration, and renamed the video 'The Cell As an Automated City.' The new title subtly suggests that a cell is designed rather than evolved."Read more of this storyat Slashdot.

    +New Software Could Warn Sailors of Rogue Waves
      Reservoir Hill writes "Sailors have been telling stories for centuries about monstrous ocean waves that tower over a hundred feet in the air and toss ships around like corks. While these were once dismissed as nautical myth, but a few years back synthetic aperture radar from ESA's ERS satellites helped establish the existence of these 'rogue' waves and study their origins. Such waves were far more common than anyone had expected. Now a researcher in Madrid has developed software that can detect rogue waves from radar images, with the possibility of providing advance warning to ships at sea. The software uses a mathematical model to evaluate and process the spatial and temporal dimensions of waves inferred from the interaction between the radar's electromagnetic energy and the sea surface. The result is displayed in a color-coded image."Read more of this storyat Slashdot.

    +Mapping the Brain's Neural Network
      Ponca City, We Love You writes "New technologies could soon allow scientists to generate a complete wiring diagram of a piece of brain. With an estimated 100 billion neurons and 100 trillion synapses in the human brain, creating an all-encompassing map of even a small chunk is a daunting task. Only one organism's complete wiring diagram now exists: that of the microscopic worm C. elegans, which contains a mere 302 neurons. The C. elegans mapping effort took more than a decade to complete. Research teams at MIT and at Heidelberg in Germany are experimenting with different approaches to speed up the process of mapping neural connections. The Germans start with a small block of brain tissue and bounce electrons off the top of the block to generate a cross-sectional picture of the nerve fibers. They then take a very thin slice, 30 nanometers, off the top of the block. 'Repeat this [process] thousands of times, and you can make your way through maybe the whole fly brain,' says the lead researcher. They are training an artificial neural network to emulate the human process of tracing neural connections to speed the process about 100- to 1000-fold. They estimate that they need a further factor of a million to analyze useful chunks of the human brain in reasonable times."Read more of this storyat Slashdot.

    +Liquid Crystal Phases of DNA, Beginning of Life?
      An anonymous reader writes "A team led by the University of Colorado at Boulder and the University of Milan has discovered some unexpected forms of liquid crystals of ultrashort DNA molecules immersed in water, providing a new scenario for a key step in the emergence of life on Earth. CU-Boulder physics Professor Noel Clark said the team found that surprisingly short segments of DNA, life's molecular carrier of genetic information, could assemble into several distinct liquid crystal phases that "self-orient" parallel to one another and stack into columns when placed in a water solution. Life is widely believed to have emerged as segments of DNA- or RNA-like molecules in a prebiotic "soup" solution of ancient organic molecules.Read more of this storyat Slashdot.

    +The Gap Between Stats and Understanding In Flu Cases
      KentuckyFC writes "Bird flu gets all the headlines but ordinary flu kills several orders of magnitude more people each year and represents a significant threat to our society. The frightening thing about ordinary flu is how little we understand about how it spreads. According to a report at the physics arXiv blog, researchers trying to model this process say they still don't know some basic probabilities associated with infection (pdf, abstract). For instance, given that the disease has manifested itself clinically in an individual, what are the chances of that person dying? And if a virus can be caught from a number of different host species (as it might eventually be with bird flu) what is the probability of transmission?"Read more of this storyat Slashdot.

    +Interconnecting Wind Farms To Smooth Power Production
      Roland Piquepaille writes "Wind power is one of the world's fastest growing electric energy sources, but as wind is intermittent, a single wind farm cannot deliver a steady amount of energy. This is why scientists at Stanford University want to connect wind farms to develop a cheaper and more reliable power source. Interconnecting wind farms with a transmission grid should reduce the power swings caused by wind variability and provide a somewhat constant and reliable electric power (or 'baseload' power) provided by other power plants."Read more of this storyat Slashdot.

    +Methane-Eating Bacteria Could Combat Global Warming
      realwx writes "New Zealand scientists have found a bacterium, named 'Methylokorus infernorum,' that eats a key global warming chemical. Found in a hot spring, the bug lives off of methane emissions from geothermically active areas. A scientist quoted in the article stated that a cubic meter of liquid containing the bacterium would consume about 11kg of methane each year. 'But Dr Stott cautioned that such an application was probably some years into the future. He said it was unlikely the micro-organism, which prefers acidic conditions of about 60C, could ever be added to sheep or cows' food to stop the animals releasing methane.'"Read more of this storyat Slashdot.

    +The Universe Damaged By Observation?
      ScentCone writes "The Telegraph covers a New Scientist report about two US cosmologists who suggest that, a la Schrodinger's possibly unhappy cat, the act of observing certain facets of our universe may have shortened its life . From the article: 'Prof Krauss says that the measurement of the light from supernovae in 1998, which provided evidence of dark energy, may have reset the decay of the void to zero — back to a point when the likelihood of its surviving was falling rapidly.'"Read more of this storyat Slashdot.

    +Russia's New Cosmodome Approved
      eldavojohn writes "You may recall discussing Baikonur, the Kazakhstan city rented by Russia that has been used as a launch site for quite some time. Today, Putin has just approved construction of Vostochny between 2010 and 2018 which will be positioned in the far east of Russia to complement the Plesetsk Cosmodrome in the northern part of the country. This is not bad news for Kazakhstan as the director of the Russian Federal Space Agency has announced they plan to operate this facility alongside Baikonur."Read more of this storyat Slashdot.

    +Earth's Moon is a Rarity
      Smivs writes "Scientists have concluded that moons like the Earth's are actually quite rare. Only 5-10% of planetary systems are likely to contain moons formed by planetary collisions. 'By the time the Earth's moon formed, when the Sun was 30 million years old, the planet formation process in our Solar System should have been approaching its end. In the latest study, Dr Gorlova's team looked at the heat signature of stars using the infrared. This allows astronomers to predict how much of that heat comes from the star itself and how much is re-emitted by dusty material encircling it.'"Read more of this storyat Slashdot.

    +Turkey Day Chemistry in the Kitchen
      instupor writes "Just in time for the holiday, PopSci runs through the food science behind moist turkey, perfect potatoes and flaky pie crust. Besides the actual "why," the article explains how to apply the scientific principals in your own kitchen."Read more of this storyat Slashdot.

    +Floating Computers Keep an Eye on the Oceans
      mightysquirrel81 writes "This fascinating picture story shows the tech behind the global Argo progamme set up to monitor the world's oceans. Using 3,000 floating computers and a network of satellites, researchers measure sea temperature and ocean currents to predict climate change."Read more of this storyat Slashdot.

    +NASA Goes Bargain Basement With New Satellite
      coondoggie writes to tell us that NASA has announced a new low-cost satellite that could be ideal for those who wish to get into space quickly and (relatively) inexpensively. "The Fast, Affordable, Science and Technology SATellite (FASTSAT) is 39.5 inches in diameter — not much larger than an exercise ball. It is hexagonally shaped and clocks in at a little less than 200 Lbs. It can carry a payload up to 110 Lbs. [...] NASA said FASTSAT is just the right size for earth observing missions, space science missions, and technology demonstrations. 'We think we can do whole missions for less than $10 million instead of the traditional $100s of millions, and that includes the launch vehicle, the satellite, and the widget you want to test,' said Marshall Space Flight Center's Edward 'Sandy' Montgomery in a release."Read more of this storyat Slashdot.
