    +Fear Detector To Sniff Out Terrorists
      Hugh Pickens writes "Evidence that the smell of fear is real was uncovered by US scientists last year who studied the underarm secretions of 20 terrified novice skydivers and foundthat people appear to respond unconsciously to the sweat smell of a frightened person. Now the Telegraph reports that researchers hope a 'fear detector'' will make it possible to identify individuals at check points who are up to no good. ''The challenge lies in the characterization and identification of the specific chemical that gives away the signature of human fear, especially the fear in relation to criminal acts,' says Professor Tong Tun at City University London who leads the team developing security sensor systems that can detect the human fear pheromone. The project will look at potential obstacles to the device, such as the effects of perfume and the variances in pheromone production and if the initial 18-month feasibility study is successful, the first detectors could be developed in the next two to three years. ''I do not see any particular reason why similar sensor techniques cannot be expanded to identify human smells by race, age or gender to build a profile of a criminal during or after an incident,'' Tong added."Read more of this storyat Slashdot.

    +Researchers Implant Neural-Monitoring RFID Into a Moth
      TechRev_AL writes "A team from the University of Washington has attached an RFID chip capable of sensing neural activity to a live moth, to pick up the spikes that occur as it beats its wings. Most neural implants are still relatively bulky, but the Washington researchers wanted to show the components in an RFID could be adapted for the same purpose. The NeuralWISP chip is a collection of low-power components such as a specialized signal amplifier, on a circuit board just over two centimeters long. The circuitry converts usable power from the reader — roughly 430 microwatts — to a voltage that can turn on a microcontroller. The sensor is also configured to 'wake up' only when a neuron fires. The ultimate goal is to create more compact, wirelessly-powered brain and nervous system implants for people."Read more of this storyat Slashdot.

    +LHC Shut Down Again — By Baguette-Dropping Bird
      Philip K Dickhead writes "Is Douglas Adams scripting the saga of sorrows facing the LHC? These time-traveling Higgs-Boson particles certainly exhibit the sign of his absurd sense of humor! Perhaps it is the Universe itself, conspiring against the revelations intimated by the operation of CERN's Large Hadron Collider? This time, it is not falling cranes, cracked magnets, liquid helium leaks or even links to Al Qaeda, that have halted man's efforts to understand the meaning of life, the universe and everything. It now appears that the collider is hindered from an initial firing by a baguette, dropped by a passing bird: 'The bird dropped some bread on a section of outdoor machinery, eventually leading to significant overheating in parts of the accelerator. The LHC was not operational at the time of the incident, but the spike produced so much heat that had the beam been on, automatic failsafes would have shut down the machine.'"Read more of this storyat Slashdot.

    +NASA May Drop Ares I-Y Test Flight
      Matt_dk writes "Just one week after the first test flight test of the Ares I-X rocket, NASA says it may decide to cancel a follow-up launch called Ares 1-Y, which wasn't scheduled until 2014. Reportedly, program managers recommended dropping the flight because, currently, there isn't the funding to get an upper stage engine ready in time. Depending on whether the Obama administration decides to continue the Ares I program, this decision may be moot. Earlier this week Sen. Bill Nelson said Obama may make a decision on NASA's future path, based on the report by the Augustine Commission, by the end of November."Read more of this storyat Slashdot.

    +LaserMotive Finds Success In Space Elevator Competition
      Bucc5062 writes "LaserMotive has achieved the first step towards the creation of a working space elevator by qualifying for the $900,000 prize in a contest sponsored by NASA. To achieve this first level, LaserMotive needed to propel a platform up a cable dangling from a helicopter at over 2 m/s. They hit a top speed of 4.13 m/s. The next level of qualification will be to achieve a climb speed greater then 5 m/s. LaserMotive beamed roughly 400 watts of laser power to a moving target at a distance of 1 kilometer, as part of the vertical laser alignment procedure. The target was a retro-reflective board a little larger than 1 meter on a side. The contest will continue for another two days with at least two other teams challenging for the prize. To win the Power Beaming competition, the LaserMotive system uses a high-power laser array to shine ultra-intense infrared light onto high-efficiency solar cells, converting the light into electric power which then drives a motor. 'Our system will track the vehicle as it climbs, compensating for motion due to wind and other changes. Building on our experience from last year’s competition, we are designing an improved system able to capture the full $2,000,000 prize.'"Read more of this storyat Slashdot.

    +Low-Energy Laser Etching May Replace Fruit Labels
      MikeChino writes "How many times have you bit into a piece of fruit only to find that you're also chomping on a sticker label? The small sticky labels have long been the bane of waste-conscious fruit and vegetable eaters, but that might all change thanks to new technology that uses a low-energy carbon dioxide laser beam to etch information directly onto produce. No more peeling those annoying labels! So far the technology is being used on a number of fruits and vegetables in New Zealand, Australia, and Pacific Rim countries, and it's currently going through the final stages of review by the FDA. Once the technology is approved in the US, researchers from the University of Florida and the USDA Agricultural Research Service hope that it will be used in Florida's massive grapefruit industry."Read more of this storyat Slashdot.

    +Volcanic Activity May Split Africa In Two
      An anonymous reader writes 'Volcanic activity may split the African continent in two, creating a new ocean, say experts. This is due to a recent geological crack which has appeared in northeastern Ethiopia.'Read more of this storyat Slashdot.

    +Why a High IQ Doesn't Mean You're Smart
      D1gital_Prob3 writes "How can a 'smart' person act foolishly? Keith Stanovich, professor of human development and applied psychology at the University of Toronto, Canada, has grappled with this apparent incongruity for 15 years. He says it applies to more people than you might think. To Stanovich, however, there is nothing incongruous about it. IQ tests are very good at measuring certain mental faculties, he says, including logic, abstract reasoning, learning ability and working-memory capacity — how much information you can hold in mind."Read more of this storyat Slashdot.

    +Murderer With "Aggression Genes" Gets Reduced Sentence
      Noiser writes "New Scientist reports: 'In 2007, Abdelmalek Bayout admitted to stabbing and killing a man and received a sentence of 9 years and 2 months. An appeal court judge in Trieste, Italy, cut Bayout's sentence by a year after finding out he has gene variants linked to aggression.'"Read more of this storyat Slashdot.

    +Placebo Effect Caught In the Act In Spinal Nerves
      SerpensV passes along the news that German scientists have found direct evidence that the spinal cord is involved in the placebo effect (whose diminishing over time we discussed a bit earlier). "The researchers who made the discovery scanned the spinal cords of volunteers while applying painful heat to one arm. Then they rubbed a cream onto the arm and told the volunteers that it contained a painkiller, but in fact it had no active ingredient. Even so, the cream made spinal-cord neural activity linked to pain vanish. 'This type of mechanism has been envisioned for over 40 years for placebo analgesia,' says Donald Price, a neuroscientist at the University of Florida in Gainesville, who was not involved in the new study. 'This study provides the most direct test of this mechanism to date.'"Read more of this storyat Slashdot.

    +Possible Dark Matter Signs At the Core
      Scientific American has a piece on speculation that dark matter may be behind diffuse radiation in the galactic center. Beginning in 2003, researchers led by Douglas Finkbeiner noticed a curious excess of microwave radiation in the WMAP data, after all known sources of such radiation were accounted for. Data from NASA's Fermi Gamma-Ray Space Telescope resulted in a similar anomaly in gamma rays. "A paper posted to the physics preprint Web site arXiv.org on October 26 and submitted to the Astrophysical Journal points to a possible signature of dark matter in the Milky Way, although the study's authors are careful to keep their observations empirical and table such speculation... In the new paper [the researchers] describe the Fermi gamma-ray haze and make the claim that it confirms the synchrotron origin of the WMAP microwave haze. And as with the microwave haze, the authors argue that the electrons responsible for the gamma-ray haze appear to originate from an unknown astrophysical process. ... 'We are absolutely in the process of exploring the Fermi haze in the context of dark matter physics,' [one of them] says."Read more of this storyat Slashdot.

    +The Tech Aboard the International Space Station
      CNETNate writes "With its own file server for uploaded Hollywood blockbusters, a 10Mbps Internet connection to Earth, and around a hundred IBM ThinkPad notebooks, the consumer technology aboard the $150 billion International Space Station is impressive. It's the responsibility of just two guys to maintain the uptime of the Space Station's IT, and they have given CNET an in-depth interview to explain what tech's aboard, how it works, and whether Windows viruses are a threat to the astronauts. In a related feature, the Space Station's internal network (which operates over bandwidth of just 1Mbps) and its connected array of Lenovo notebooks is explained, along with the tech we could see in the future."Read more of this storyat Slashdot.

    +2 Companies Win NASA's Moon-Landing Prize Money
      coondoggie writes "NASA said it will this week award $1.65 million in prize money to a pair of aerospace companies that successfully simulated landing a spacecraft on the moon and lifting off again. NASA's Centennial Challenges program, which was managed by the X Prize Foundation, will give a $1 million first prize to Masten Space Systems and a $500,000 second prize to Armadillo Aerospace for successfully completing the Northrop Grumman Lunar Lander Challenge."Read more of this storyat Slashdot.

    +Scientists Build a Smarter Rat
      destinyland writes "Scientists have engineered a more intelligent rat, with three times the memory length of today's smartest rats. Reseachers bred transgenic over-expression of the NR2B gene, which increased communication between the rat's memory synapses. Activating a crucial brain receptor for just a fraction of a second longer produces a dramatic effect on memory, as proven by the rat's longer memories of the path through a maze."Read more of this storyat Slashdot.
