Global 'Sunscreen' Has Likely Thinned, Report NASA Scientists

A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases - sunlight blocked by dust, pollution and other aerosol particles - appears to have lost ground.

 Years of comparisons among the world's best atomic clocks-based on different atoms-have established the most precise limits ever achieved in the laboratory for detecting possible changes in so-called "constants" of nature. The comparisons at the National Institute of Standards and Technology (NIST) may help scientists test the latest theories in physics and develop a more complete understanding of the history of the universe.

 The best oceanographers in the world never studied at a university. Yet they know how to navigate expertly along oceanic fronts, the invisible boundaries between waters of different temperatures and densities. These ocean experts can find rich fishing in places and at depths that others would assume are barren. They regularly visit the most interesting and dynamic parts of the sea.
