  • Exercise and Arthritis

    Adding another incentive to exercise, scientists at Duke University Medical Center have found that physical activity improves arthritis symptoms – even among obese mice that continue to eat a high-fat diet. The insight suggests that excess weight alone isn’t what causes the aches and pains of osteoarthritis, despite the long-held notion that carrying extra pounds…

  • Safe Pathways for Amphibians

    As the world , much less the climate, changes, species must change and move too. A species ability to overcome adversity goes beyond Darwin’s survival of the fittest. In a new study based on simulations examining species and their projected range, researchers at Brown University argue that whether an animal can make it to a…

  • Study: China to Surpass US Per Capita Emissions by 2017

    The biggest polluters in the world are known to be the United States of America and China. In 2007, China overtook the United States for the dubious role of world’s greatest carbon emitter. However, because the United States is so much wealthier per capita than the People’s Republic, individual US citizens could claim that they…

  • The Amazing Decline of Deaths From Extreme Weather

    With climate change, the world is generally getting warmer –- but not in a slow and straight line. Instead, many models show that weather is simply becoming more unpredictable and possibly more volatile, with more severe storms, more severe droughts and more peaks in all kinds of weather extremes. All of that volatility raises its…

  • Deepwater oil spill likely to hurt fish populations over decades

    Oil pollution doesn’t have to kill fish to have a long-term impact, according to a recent study in the Proceedings of the National Academy of Sciences (PNAS). Researchers found that Gulf killifish (Fundulus grandis) that had been exposed to very low to non-detectable levels of oil contamination from the Deepwater oil spill last year, still…

  • New Zealand adjusts its CO2 trading program to address market distortions

    New Zealand is looking to exclude the use of U.N. offsets from industrial gas projects in its emissions trading scheme from as soon as 2012, as these offsets threaten to distort the market, the government said on Friday. Climate change minister Nick Smith said he wanted to maintain the integrity of the emissions trading scheme,…

  • Afghanistan Mineral Potential

    Mineral deposits can create jobs, industry, wealth and potentially pollution. It could help stabilize a war torn country such as Afghanistan. Working with the Department of Defense Task Force for Business and Stability Operations (TFBSO), members of the USGS Minerals Project assessed fuel- and non-fuel mineral resources of Afghanistan from October 2009 to September 2011…

  • An Efficient Solar Harvest

    Solar power could be harvested more efficiently and transported over longer distances using tiny molecular circuits based on quantum mechanics, according to research inspired by new insights into natural photosynthesis. Incorporating the latest research into how plants, algae and some bacteria use quantum mechanics to optimize energy production via photosynthesis, UCL scientists have set out…

  • Coral Reefs likely to disappear by the end of the century

    Coral reefs will be gone by the end of the century, according to a top UN Scientist. This would give coral reefs the dubious accolade of being the first entire ecosystem to have been destroyed by human activity. In the recently published book ‘Our Dying Planet’, Professor Peter Sale writes that coral reef ecosystems are…

  • Hilary becomes Category 4 hurricane, Mexican coast on alert

    Hilary, a small but powerful storm, strengthened to a Category 4 hurricane late on Thursday as its core continued to move parallel to the southwest Pacific coast of Mexico. The storm was 85 miles southwest of the popular resort of Acapulco, packing maximum sustained winds of 135 miles per hour, the Miami-based National Hurricane Center…
