  • New York State power plants showing their age

    New York State could face power plant closings in the near future as a result of updated environmental regulations and the fact that plants in the state are outdated and inefficient; a recent report concluded that New York’s coal and nuclear power plants, as well as steam and turbine plants that run on oil or gas, are on average older than others around the country

  • A 1-kilometer-long electric sail tether brings space sailing closer

    The electric sail (ESAIL) produces propulsion power for a spacecraft by utilizing the solar wind; the sail features electrically charged long and thin metal tethers which interact with the solar wind; using ultrasonic welding, researchers have successfully produced a 1-km long ESAIL tether; the produced tether proves that manufacturing full size ESAIL tethers is possible; the theoretically predicted electric sail force will be measured in space during 2013

  • Portable X-ray source offers a mobile terrorism prevention tool

    The hand-held scanners, or tricorders, of the Star Trek movies and television series are one step closer to reality now that a engineers have invented a compact source of X-rays and other forms of radiation; the radiation source, which is the size of a stick of gum, could be used to create inexpensive and portable X-ray scanners for use by doctors, as well as to fight terrorism and smuggling and aid exploration on this planet and others

  • A dandelion-shaped device to help in demining operations

    Decades of war have left land mines buried all over the Afghan countryside; they continue to go off, killing and maiming hundreds of  innocent people every year; last year alone, more than 812 people were wounded or killed in Afghanistan because of mines left behind after the armies retreated; two Afghan inventors designed a dandelion-like device for demining operations

  • "Prophylactic dressing" for walls make buildings safer during earthquakes

    In the case of earthquakes, only seconds may remain for a safe escape from buildings; debris falling down and obstructing the escape routes may even aggravate the situation; a new product extends the time for saving lives by reinforcing walls and keeping off the debris; an innovative building material manufacturer now has launched the mature innovation in the market

  • Assessing future sea level rise from ice sheets

    Future sea level rise due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than estimated in Climate Change 2007, the Fourth Assessment Report of the IPCC, according to new research

  • BP settlement includes $350 million funding for Gulf health, environmental protection

    As part of the $4 billion settlement announced last month between the federal government and BP concerning the 2010 Deepwater Horizon disaster, the National Academy of Sciences has been asked to establish a new $350 million, 30-year program on human health and environmental protection in the Gulf of Mexico

  • Free STEM search engine is now mobile

    Gooru — a free search engine for learning that brings together science, technology, engineering, and mathematics (STEM) educational materials on the Web — developed the Gooru Collections iPad app to bring thousands of assorted multimedia resources to teachers and students on the go

  • Neuroscience study reveals new link between basic math skills and PSAT math success

    New research provides brain imaging evidence that students well-versed in very basic single digit arithmetic (5+2=7 or 7-3=4) are better equipped to score higher on the Preliminary Scholastic Aptitude Test (PSAT), an examination sat by millions of students in the United States each year in preparation for college admission tests

  • Smartphones turned into secure and versatile keys

    It is already possible to open doors using an app — but we are a long way from seeing widespread acceptance of this in the market; now, researchers have developed a piece of software that will make the technology even more secure and versatile

  • Political action the biggest swing factor in meeting climate targets: study

    The new study examines the probability of keeping average global temperatures from rising more than 2°C above preindustrial levels under varying levels of climate policy stringency, and thus mitigation costs

  • Flexible electronics to make night vision more accurate, easier to use

    For soldiers and first responders, having accurate, high-resolution imaging capabilities may mean the difference between success and failure; electrical and computer engineers set out to make night vision more accurate and easier for soldiers, pilots, and first responders to use

  • The natural relationship between CO2 concentrations and sea level means that sea level will continue to rise

    By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past forty million years, researchers have found that greenhouse gas concentrations similar to the present (almost 400 parts per million) were systematically associated with sea levels at least nine meters above current levels

  • Less-lethal 12-gauge shotgun round for law enforcement unveiled

    Innovative new round flattens, or “pancakes,” across a subject’s body on impact rather than keeping its shape as other rounds do
