(PhysOrg.com) -- Used in Hollywood and the advertising industry to create exotic special effects, ferrofluids are seemingly magical materials that are both liquid and magnetic at once. In a study published today in Physical Review B, Yale electrical engineering professor Hur Koser and colleagues from the University of Georgia and Massachusetts Institute of Technology demonstrate for the first time an approach that allows ferrofluids to be pumped by magnetic fields alone. The invention could lead to new applications for this mysterious material.

The explosion and fire on a BP-licensed oil platform in the Gulf of Mexico in April 2010 had huge environmental and economic effects, with millions of gallons of oil leaking into the water for more than five months. It also had significant psychological impact on people living in coastal communities, even in those areas that did not have direct oil exposure, according to researchers.

A new analysis of sulfur emissions shows that after declining for a decade, worldwide emissions rose again in 2000 due largely to international shipping and a growing Chinese economy. An accurate read on sulfur emissions will help researchers predict future changes in climate and determine present day effects on the atmosphere, health and the environment.
