• How wings really lift

    See video

    A wing lifts when the air pressure above it is lowered. The explanation typically offered in high school and college physics courses is that this happens because the airflow moving over the top, curved surface has a longer distance to travel and needs to go faster to have the same transit time as the air travelling along the lower, flat surface. This is the wrong explanation, and a 1-minute video released by the University of Cambridge sets the record straight on this much misunderstood concept — how wings lift

  • Preparing for the end of the world as we know it

    In a growing trend, more and more Americans across the United States are preparing themselves for a catastrophic apocalypse; for reasons ranging from terrorists to natural disasters or an economic meltdown, these individuals have begun stockpiling food, taking survival courses, or constructing safe rooms

  • Wetlands capture more carbon than earlier thought

    New study shows that wetlands in temperate regions are more valuable as carbon sinks than current policies imply; the study found that the stagnant wetland had an average carbon storage rate per year that is almost twice as high as the carbon storage rate of the flow-through wetland

  • Students compete in zero-gravity robotic competition

    Two hundred high school students were on the campus of Massachusetts Institute of Technology (MIT) on Monday for a competition to program miniature satellites aboard the International Space Station

  • First responders could be zipping through skies within two years

    Glenn Martin, the inventor of the Martin Jetpack, the world’s first commercially available jetpack, recently spoke with Homeland Security NewsWire’s executive editor Eugene K. Chow; in their interview Martin discusses the technical challenges of developing a viable jetpack, its uses in emergency response, and when we can expect to see civilians zipping through the skies

  • World’s first magnetic soap can clean oil spills

    A University of Bristol team has dissolved iron in liquid surfactant to create a soap that can be controlled by magnets; the discovery could be used to create cleaning products that can be removed after application and used in the recovery of oil spills at sea

  • Shrew whiskers inspire robot design

    The Etruscan shrew is nocturnal, relying on its whiskers to find, track, and capture its prey; the efficiency of this tiny creature has inspired scientists to look at ways of replicating the shrew’s whiskers to enable robots to find their way around without the use of vision

  • Mysterious flotsam in Gulf came from Deepwater Horizon rig

    Scientists track debris from damaged oil rigs, helping forecast coastal impacts in the future

  • New robot for search-and-rescue missions

    Scientists say the best way to design a new machine is to emulate the locomotion of a certain type of flexible, efficient animal

  • Slowing down sea-level rise vs. reducing surface temperature change rate

    Scientists say that reducing the amount of solar radiation hitting Earth (for example, by satellites that block the sun, making the Earth’s surface more reflective, or emulating the effects of volcanoes by placing aerosol particles in the upper atmosphere) would be a cheaper way to halt or reverse climate change than reducing carbon dioxide emissions

  • Improving autonomous navigation in challenging conditions

    Researchers work on developing an advanced sensor fusion system for the Department of Defense that will increase high-speed obstacle detection range; results of this work should open up new possibilities for deploying autonomous vehicles for missions that demand navigating at higher speeds in unstructured environments

  • La Nina weather pattern may lead to flu pandemics?

    Pandemics of influenza around the world caused widespread death and illness in 1918, 1957, 1968, and 2009; a new study examining weather patterns around the time of these pandemics found that each of them was preceded by La Niña conditions in the equatorial Pacific

  • Walden University offers M.S. in Emergency Management

    The school says that this new online master’s degree program emphasizes key skills related to creating and implementing disaster prevention and response plans

  • Digital images used to prevent bridge failures

    A new/old method has been developed to assure the safety of hundreds of truss bridges across the United States; researchers have been testing the use of a thoroughly modern version of an old technique — photographic measurement or “photogrammetry” — to watch the failure of a key bridge component in exquisite detail

  • Scientists study how nature cleans uranium from aquifer

    A small town in Colorado was the site of uranium ore processing in the 1940s and 1950s, producing yellowcake; when the mills shut down, the mill tailings — a crushed rock byproduct of ore processing — were left behind on the north bank of the river; the tailings were hauled away in the 1990s, but a large amount of uranium that seeped out of the tailings remains as a contaminant in the aquifer and is slowly being released into the Colorado River
