  • Landmark US Geological Survey study demonstrates how methylmercury, known to contaminate seafood, originates in the ocean

    A new landmark study published today documents for the first time the process in which increased mercury emissions from human sources across the globe, and in particular from Asia, make their way into the North Pacific Ocean and as a result contaminate tuna and other seafood. Because much of the mercury that enters the North Pacific comes from the atmosphere, scientists have predicted an ...

  • Space tech helps to find natural resources

    Using space-based technology developed during ESA’s gravity mission studies, a novel gradiometer is being developed by a UK-based company to help oil and gas companies find the most appropriate locations to drill wells and plan further exploration. The gravity gradiometer measures the variations in the Earth’s gravity, or in technical terms, the ‘differential acceleration’. These variations ...

  • Berkeley Lab receives US$7m for enhanced geothermal energy technologies

    As the world’s energy needs grow ever greater, scientists are charged with finding new ways to expand clean-energy resources and tap new ones. One such resource is geothermal energy, or heat mining, in which the heat acquired by fluid circulation deep in the Earth’s crust is tapped for conversion to electricity. Lawrence Berkeley National Laboratory has been awarded $7 million in American ...
