Researchers at the National Institute of Standards and Technology (NIST) have done a mash-up of two very different experimental techniques-neutron scattering and electrochemical measurements-to enable them to observe structural changes in nanoparticles as they undergo an important type of chemical r...
An international team of physicists-including several from the California Institute of Technology (Caltech)-has detected and measured, for the first time, a transformation of one particular type of neutrino into another type. The finding, physicists say, may help solve some of the biggest mysteries ...
Sirenians, or seacows, are a group of marine mammals that include manatees and dugongs; today, only one species of seacow is found in each world region. Smithsonian scientists have discovered that this was not always the case. According to the fossil record of these marine mammals, which dates back ...
Tropical Storm Irina continues to linger in the Mozambique Channel, and NASA satellite data revealed the strongest storms in the southern quadrant, and Irina is running into some dry air, which may help to weaken it as it moves back to the African mainland.
An international team of physicists has developed a method for taking ultrafast 'sonograms' that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through an important physical process called a phase transition.
The 2011 Tohoku tsunami was Japan's deadliest in more than 100 years. Despite an extraordinary level of preparedness by the Japanese, the tsunami caused more than 90 percent of the almost 20,000 fatalities last March. Georgia Tech Associate Professor Hermann Fritz and his research team are studying...
Long-delayed effort by EIA will quantify a decade of energy efficiency gains and focus decision-makers around higher standards. By Maria Gallucci, InsideClimate News The recent explosion of efficiency efforts across the country has slashed energy use in U.S. buildings, but by how much, exactly? A...
In both war and peacetime scenarios, fire in the shipboard environment is serious and frequently results in excessive damage and high repair costs because the fire is not detected or controlled adequately. To help further improve future shipboard firefighting capability scientists at the Naval Resea...
A research group led by Dr. A. Claudio Cuello of McGill University's Faculty of Medicine, Dept. of Pharmacology and Therapeutics, has uncovered a critical process in understanding the degeneration of brain cells sensitive to Alzheimer's disease (AD). The study, published in the February issue of the...
Scientists have found a way to trick the immune system into accepting organs from a mismatched, unrelated organ donor, a finding that could help patients avoid a lifetime of drugs to prevent rejection of the donated organ.
A team of paleontologists has discovered the oldest animal with a skeleton. Called Coronacollina acula, the organism is between 560 million and 550 million years old, which places it in the Ediacaran period, before the explosion of life and diversification of organisms took place on Earth in the Cam...
NASA models using data from the Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) have now provided more information about the two CMEs associated with the two March 6 flares. The first is traveling faster than 1300 miles per second; the second more than ...
