• Bolstering e-mail security

    On the whole, security is not a primary concern for most day-to-day e-mails, but some e-mails do contain personal, proprietary, and sensitive information, documents, media, photos, videos, and sound files; the open nature of e-mail means that they can be intercepted and if not encrypted, easily read by malicious third parties

  • Canada funds digital technology to enhance maritime security, surveillance

    New funding will allow exactEarth to improve its ability to locate more than 80,000 ships daily anywhere around the world and transmit this information quickly to its customers; this data is used within Canada and globally for a number of purposes, including enhancing maritime security and surveillance as well as search and rescue support

  • There is enough wind power to meet global energy demand

    There is enough energy available in winds to meet all of the world’s demand; atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- and ocean-based units

  • Predicting waves’ height, force could double marine-based energy

    In the search for alternative energy, scientists have focused on the sun and the wind; there is also tremendous potential in harnessing the power of the ocean’s waves, but marine energy presents specific challenges that have made it a less promising resource; one of these challenges is the fact that waves differ in terms of their size and force; forecasting wave height one second in advance optimizes energy collection

  • Next generation of advanced climate models needed

    From farmers deciding which crops to plant next season, to mayors preparing for possible heat waves, to insurance companies assessing future flood risks, to those responsible for infrastructure protection having to decide how best to use scarce resource to mitigate climate change-induced disasters, an array of stakeholders from the public and private sectors rely on and use climate information; the U.S. National Research Council says he U.S. collection of climate models should advance substantially to deliver more detailed, smaller scale climate projections

  • Urchin-loving otters can help fight global warming

    A thriving sea otter population that keeps sea urchins in check will in turn allow kelp forests to prosper; the spreading kelp can absorb as much as twelve times the amount of CO2 from the atmosphere than if it were subject to ravenous sea urchins

  • Raytheon opens STEM teacher award program

    Raytheon has opened the 2012 application process for its Raytheon-Engineering is Elementary (EiE) Teacher Scholarship Program; during the 2012-13 school year, Raytheon will grant awards of $3,000 each for selected elementary school teachers nation-wide whose applications best demonstrate innovative methods of generating student enthusiasm about engineering concepts

  • New search-and-rescue tool: remotely controlled cockroaches

    Researchers have developed a technique that uses an electronic interface to remotely control, or steer, cockroaches; remotely controlling cockroaches would allow first responders to create a mobile web of smart sensors that uses cockroaches to collect and transmit information, such as finding survivors in a building that has been destroyed by an earthquake

  • Protecting buildings from earthquakes by hiding them

    Engineers have come up with an inventive and exciting idea for protecting buildings from earthquakes: hide them (the buildings, that is); the engineers say that placing specialized rubber under the building would diverts certain temblor shock waves, leaving the building virtually untouched by them

  • Scientists question earthquake prediction methods

    From 2008 to 2011, three earthquakes have significantly damaged different parts of the world. Those quakes were significantly underestimated by scientists and seismologists

  • Crack-resistant components for bridges, roof structures, cars

    Bridges, roof structures, cars, and more should become increasingly lighter, with the same stability, and thus save energy and materials; the new high-strength steel is superbly suited for the needed lightweight design because it can also withstand extremely heavy stresses; yet these materials also have a disadvantage: with increasing strength, their susceptibility to cold cracking rises when welded; cracks are difficult to predict — until now

  • Airbus unveils its 2050 vision for “Smarter Skies”

    Global aircraft manufacturer Airbus the other day released the latest installment of the Future by Airbus, its vision for sustainable aviation in 2050 and beyond; the vision looks beyond aircraft design to how the aircraft is operated both on the ground and in the air in order to meet the expected growth in air travel in a sustainable way

  • Destroyed coastal habitats produce significant amounts of greenhouse gas

    Destruction of coastal habitats may release as much as one billion tons of carbon into the atmosphere each year, ten times higher than previously reported; a new analysis provides the most comprehensive estimate of global carbon emissions from the loss of these coastal habitats to date: 0.15 to 1.2 billion tons; it suggests there is a high value associated with keeping these coastal-marine ecosystems intact as the release of their stored carbon costs roughly $6-$42 billion annually

  • Students create low-cost biosensor to detect contaminated water

    Diarrheal disease is the second-leading cause of death in children under five years old — killing as many as 1.5 million children worldwide every year; these startling statistics from the World Health Organization (2009) point to the reason why a group of undergraduate students from Arizona State University is working to develop a low-cost biosensor — a simple device that would detect contaminated drinking water

  • DHS funds more tests of autonomous power buoy for ocean surveillance

    Ocean Power Technologies (OPT) has entered into an agreement with DHS Science & Technology Directorate to perform a new round of in-ocean tests on the company’s Autonomous PowerBuoy to demonstrate its use for ocean surveillance
