Water matters to metal nanoparticles‎

When you purchase anything from makeup to paint to sunscreen, chances are it contains engineered nanoparticles. These nanoscale materials have properties that are revolutionizing products—from medicine to agriculture to electronics. But eventually, those nanoparticles will reach natural environments. To use them safely and to their fullest potential, we need to know how they behave in real environments—and if that behavior leads to any unintended consequences.

Scientists find way to make mineral which can remove CO2 from atmosphere‎

Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO2 from the atmosphere for long-term storage, thus countering the global warming effect of atmospheric CO2. This work is presented at the Goldschmidt conference in Boston.

First reliable estimates of highly radioactive cesium-rich microparticles released by Fukushima disaster‎

Scientists have for the first time been able to estimate the amount of radioactive cesium-rich microparticles released by the disaster at the Fukushima power plant in 2011. This work, which will have significant health and environmental implications, is presented at the Goldschmidt geochemistry conference in Boston.

When mixing granular matter, order among disorder‎

Mixing liquids is easy, or at least scientifically understood: a drop of food coloring will eventually mix into a cup of water through diffusion, and a dollop of cream can be mixed into coffee with a spoon through what is called turbulent mixing.

Researchers use green gold to rapidly detect and identify harmful bacteria‎

Researchers from the University of Minnesota (UMN) have developed a method to screen and identify harmful or antibiotic-resistant bacteria within one hour using a portable luminometer. Traditional diagnostic methods often require complex equipment and lab work that can take days. The new method uses chemiluminescence, or the emission of light during a chemical reaction. It was developed with the food industry in mind and could also be used in healthcare settings.

NASA-NOAA's Suomi NPP satellite sees Bebinca east of Hainan Island‎

China's Hainan Island can't seem to get away from slow moving Tropical Storm Bebinca. The storm continues to linger near the island on Aug. 14 as seen when NASA-NOAA's Suomi NPP satellite passed overhead and captured a visible image of the storm in Aug. 14. In fact, Hainan Island is expected to get another visit from the storm.

Lipid droplets play crucial roles beyond fat storage‎

Lipid droplets: they were long thought of merely as the formless blobs of fat out of which spare tires and muffin tops were made. But these days, they're "a really hot area of research," says Michael Welte, professor and chair of biology at the University of Rochester.
