• Finding Arctic Cyclones

    From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes – and melting sea ice in the Arctic Ocean. That's about 40 percent more of these Arctic storms than previously thought, according to a new study of vast troves of weather data that previously were synthesized at the Ohio Supercomputer Center (OSC). A 40 percent difference in the number of cyclones could be important to anyone who lives north of 55 degrees latitude – the area of the study, which includes the northern reaches of Canada, Scandinavia and Russia, along with the state of Alaska. >> Read the Full Article
  • Dueling fruit flies

    Apparently male fruit flies fight. Who knew? According to biologist David Anderson from the fly laboratory of California Institute of Technology (Caltech), Drosophilae, commonly known as fruit flies, fight regularly. Males in particular put up a big fight in the presence of a female because males have special cells in their brains that promote fighting that are absent in the brains of female fruit flies. >> Read the Full Article
  • Chemicals of Emerging Concern (CECs) identified in sewage sludge

    Thousands of chemicals serving a variety of human needs flood into sewage treatment plants once their use life has ended. Many belong to a class of chemicals known as CECs (for chemicals of emerging concern), which may pose risks to both human and environmental health. Arjun Venkatesan and Rolf Halden of Arizona State University's Biodesign Institute have been tracking many of these chemicals outlining a new approach to the identification of potentially harmful, mass-produced chemicals, describing the accumulation in sludge of 123 distinct CECs. >> Read the Full Article
  • The girth of a tree

    Thank goodness human growth rates don't match that of trees. For if it did then we would tip the scales of well over a ton by the time we reach retirement! Consider this new research from the Smithsonian Tropical Research Institute (STRI) recently published in the journal Nature. According to the new study, trees put on weight faster and faster as they grow older. Because most trees' growth accelerates as they age this suggests that large, old trees may play an unexpectedly dynamic role in removing carbon from the atmosphere. >> Read the Full Article
  • Burning fewer calories: the elixir for longevity

    New research shows that humans and other primates burn 50% fewer calories each day than other mammals. The study, published January 13 in the Proceedings of the National Academy of Sciences, suggests that these remarkably slow metabolisms explain why humans and other primates grow up so slowly and live such long lives. The study also reports that primates in zoos expend as much energy as those in the wild, suggesting that physical activity may have less of an impact on daily energy expenditure than is often thought. >> Read the Full Article
  • Popularity of plug-in vehicles on the rise

    Good news for those living at the intersection of manufacturing and environmentalism. Here in the U.S., sales of plug-in electric and hybrid vehicles almost doubled between 2012 and 2013 with an 84 percent jump to 96,600 of the vehicles sold. That’s 49,000 plug-in hybrids (like the Volt) and 47,600 pure battery powered plug-in vehicles sold. >> Read the Full Article
  • Tree Island restoration

    Worldwide, large swaths of land lay barren in the wake of agricultural expansion, and as global forest cover continues to decline, carbon and water cycles, biodiversity, and human health are impacted. But efforts to restore abandoned pastures and agricultural plots back into functioning forest ecosystems are often hindered by high costs and time requirements. Fortunately, scientists have developed a new method for a more cost effective solution to forest restoration, the establishment of "tree islands." >> Read the Full Article
  • Spitting Sulfates!

    In 1991, Mount Pinatubo in the Philippines erupted in one of the largest volcanic blasts of the 20th century. It spat up to 20 million tons of sulfur into the upper atmosphere, shielding the earth from the sun's rays and causing global temperatures to drop by nearly half a degree Celsius in a single year. That's more than half of the amount the planet has warmed due to climate change in 130 years. >> Read the Full Article
  • Giant wave of understanding in South China Sea

    Their effect on the surface of the ocean is negligible, producing a rise of just inches that is virtually imperceptible on a turbulent sea. But internal waves, which are hidden entirely within the ocean, can tower hundreds of feet, with profound effects on the Earth's climate and on ocean ecosystems. Now new research, both in the ocean and in the largest-ever laboratory experiments to investigate internal waves, has solved a longstanding mystery about exactly how the largest known internal waves, in the South China Sea, are produced. The new findings come from a team effort involving MIT and several other institutions, and coordinated by the Office of Naval Research (ONR). >> Read the Full Article
  • Annual home checkup should include a radon test

    Because 21,000 Americans die each year from radon related lung cancer the EPA recommends an annual testing of radon in the home. By making January “Radon Action Month” homeowners can protect their family from this leading cause of lung cancer among non-smokers and DIY test kits are as low as $10. >> Read the Full Article
