• Electronegativity will simplify chemistry education, allows new research

    Researchers at Oregon State University have created a new, unifying method to describe a basic chemical concept called “electronegativity,” first described almost eighty years ago by OSU alumnus Linus Pauling and part of the work that led to his receiving the Nobel Prize

  • Registration for CyberPatriot IV competition to end this week

    With less than a week left before registration closes, CyberPatriot IV, the National High School Cyber Defense Competition, has more than 850 teams registered; this competition is attracting high school educators across the United States; the structure of the competition provides students hands-on learning while competing virtually against their peers and introduces many to the idea of cyber security as a profession

  • Teaching sensors to think for themselves

    There is a major problem with sensors: data overload; as sensors gather more and more information, it has become increasingly difficult for human users to separate out what is relevant from what is not; two U Vermont researchers received a grant from DARPA to teach sensors what to look for — and what not to look for

  • Defying governor, Mass. officials seek to join Secure Communities

    Local law enforcement officials and state lawmakers are increasingly working to circumvent Massachusetts governor Deval Patrick’s decision to opt out of the controversial Secure Communities immigration program; last Wednesday U.S Senator Scott Brown (R-Massachusetts) called on DHS secretary Janet Napolitano to allow the state to join Secure Communities without Governor Patrick’s approval; Under Secure Communities, a detained individual’s fingerprints are automatically scanned and checked against DHS and FBI databases to determine their immigration status

  • Safe, efficient cookstoves for earthquake survivors

    316,000 people were killed and more than one million made homeless by the 12 January 2010 magnitude 7.0 quake that left the capital city of Port-au-Prince in ruins; many of the displaced Haitians still live in tent cities, where even simple tasks such as cooking are a challenge; scientists hope to find the safest and most energy-efficient way for earthquake survivors to cook

  • Self-repairing composites repair cracks in coating of buildings, bridges

    Researchers have developed vascularized structural composites, creating materials that are lightweight and strong with potential for self-healing, self-cooling, metamaterials, and more; these artificial microvascular systems can self-repair of materials damage, such as cracks in a coating applied to a building or bridge

  • Solar UV disinfects drinking water

    More than 800 million people around the world lack access to clean water; the water available for people to drink in many developing countries has not been treated to remove contaminants, including pathogenic microorganisms; half of the world’s hospital beds are occupied by people who are sickened by the water they drink; Purdue University researchers have invented a water-disinfection system that uses the sun’s ultraviolet radiation to inactivate waterborne pathogens

  • Protecting structures against firebrand attack

    NIST engineers have built a device that bellows showers of glowing embers, or firebrands, to test how structures can withstand this destructive aspects of wild fires; in Japan, where the device is now used in a test facility, firebrands are a growing peril that accounts for half of the nation’s ten most costly fires

  • Belief that others can change could bring peace

    Psychologists find that members of groups engaged in conflict are more willing to compromise if they believe people are capable of changing; when researchers presented Israelis and Palestinians with evidence that groups of people are capable of change, the information increased the subjects’ willingness to compromise on key political issues

  • E-textiles now come with memory-storing fiber

    E-textiles could help soldiers, first responders — but also the sick and infirm; the integration of electronics into textiles is a growing field of research that may soon enable smart fabrics and wearable electronics

  • Georgia shows app that prepares state residents, guides them to safety

    New Ready Georgia mobile app uses geo-location to deliver alerts, create emergency plans, and show shelter locations; from up-to-the-minute weather and hazard alerts based on a user’
    ‘s location, to customizable emergency preparedness checklists, the app combines a set of features not previously available in one mobile application

  • Shells tracked by radar

    With the high costs of live fire training, the Pentagon wanted a shell-scoring system, and commissioned Cambridge Consultants to develop one; after fourteen months of development, the company unveiled its holographic radar scoring system, the Land and Surface Target Scorer (LSTS)

  • Anti-magnet: to protect ships' hulls from mines

    Researchers have created a new type of magnetic cloak which shields objects from magnetic fields — at the same time that it prevents any internal magnetic fields from leaking out; this “antimagnet” could be used to protect a ship’s hulls from mines that detonate when a magnetic field is detected

  • The Certified Protection Officer (CPO) 8th Edition launched

    The updated version of a training course for Certified Protection Officers is now available online; the course and exam provide candidates with the IFPO certification; the course offers training in security technology, laws, trends, and techniques

  • Global water market could hit $800 billion by 2035

    Analysts are predicting that the global market for water could grow dramatically over the next two decades, with some projecting a $1 trillion market in 2020; “Water is the fastest growing market at the moment, with a size of $500 billion globally,” said Harri Kerminen, the president and CEO of Finnish chemical firm Kemira
