• Global warming unequivocal in its advance, says NCAA expert

    Global warming is unequivocal in its advance and will lead to more record-setting temperatures, says Warren Washington, a senior scientist at the National Center for Atmospheric Research; in a talk at Sandia Lab, Washington presented graph after graph showing how various atmospheric processes have combined to create stronger rainfall near the equator and more intense droughts in the subtropics, as well as sea-level rises and increased storm surges

  • Predictions by climate models are flawed, says MIT meteorology expert

    Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, says that too much is being made of climate change by researchers seeking government funding; he said their data and their methods did not support their claims; for thirty years, climate scientists have been “locked into a simple-minded identification of climate with greenhouse-gas level. That climate should be the function of a single parameter (like CO2) has always seemed implausible. Yet an obsessive focus on such an obvious oversimplification has likely set back progress by decades,” Lindzen said

  • A device used to measure nuclear weapons effects is now used for rocket propulsion system

    Can a device formerly used to test nuclear weapons effects find a new life in rocket propulsion research? That is the question in which researchers seek an answer; when assembled, the device will tip the scales at nearly fifty tons, and will be “one of the largest, most powerful pulse power systems in the academic world,” according to one researcher

  • Large, magnitude 8 earthquakes hit New Zealand with regularity

    A new study finds that very large earthquakes have been occurring relatively regularly on the Alpine Fault along the southwest coastline of New Zealand for at least 8,000 years

  • Studying the physics of avalanches

    Snow avalanches, a real threat in countries from Switzerland to Afghanistan, are fundamentally a physics problem: What are the physical laws that govern how they start, grow, and move, and can theoretical modeling help predict them? New study offers answers

  • Winners of the California Cyber Summer Camp Capture the Flag competition announced

    Cal Poly Pomona, in partnership with Booz Allen Hamilton and the U.S. Cyber Challenge, hosted the U.S. Cyber Challenge California Cyber Summer Camp in Pomona, California; the camp curriculum included in-depth workshops on a range of topics, including penetration testing, reverse engineering, and forensics; the week was capped off by a virtual “capture the flag” competition and awards ceremony on the last day

  • Researchers say spoofed GPS signals can be countered

    From cars to commercial airplanes to military drones, global positioning system (GPS) technology is everywhere — and researchers have known for years that it can be hacked, or as they call it, “spoofed”; the best defense, they say, is to create countermeasures that unscrupulous GPS spoofers can not deceive

  • Game lets players try their hand at computer security

    A new game — Control-Alt-Hack — gives teenage and young-adult players a taste of what it means to be a computer-security professional defending against an ever-expanding range of digital threats; the game’s creators will present it this week in Las Vegas at Black Hat 2012; educators in the continental United States can apply to get a free copy of the game while supplies last; it is scheduled to go on sale in the fall for a retail price of about $30

  • Capturing CO2 directly from air is chemically, economically viable

    With a series of papers published in chemistry and chemical engineering journals, researchers from the Georgia Institute of Technology have advanced the case for extracting carbon dioxide directly from the air using newly developed adsorbent materials

  • Pulling CO2 from air feasible, if still costly, way to curb global warming

    Emerging techniques to pull carbon dioxide from the air and store it away to stabilize the climate may become increasingly important as the planet tips into a state of potentially dangerous warming; lower-cost technology is a stumbling block so far

  • New U.S. biodedfense R&D network launched

    On Monday, Texas A&M System dedicated a new research center which is part of a national network of centers aiming to develop strategies and products to counter bioterrorism, chemical and radiological attacks on the United States, and better strategies to deal with pandemics; the network will have facilities in Texas, Maryland, and North Carolina; the Texas dedication is the culmination of a Manhattan Project-like program for biological countermeasures, launched in 2004 by the Department of Health and Human Services; the research network aims to develop “rapid, nimble and flexible approaches” to vaccine and therapy development, and train the next generation of professionals to sustain U.S. capabilities in these areas

  • You want to report a pothole? There’s an app for that

    The city of Boston offers residents a new app – Street Bump – which will automatically report potholes they encounter; all the driver has to do is install the app and place the smartphone on the dashboard or in the cup holder; the app uses the phone’s motion detector and GPS locator to report potholes

  • Temperature rise, CO2 follow each other closely

    The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period; new research indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time

  • Selfish-herd theory confirmed

    Many animals spend time together in large groups not because they enjoy each other’s company, but rather because it lowers their own chances of being eaten should an uninvited guest arrive on the scene — or so the theory goes; now, researchers who have strapped GPS-enabled backpacks to flocking sheep and a herding dog provide some of the first hard evidence that this “selfish herd theory” is true

  • Engineering students race first 3-D printed boat in Milk Carton Derby

    University of Washington mechanical engineering students braved uncharted waters as they paddled to the finish line at the annual Milk Carton Derby at Green Lake in Seattle in what they believe is the world’s first boat made using a 3-D printer
