Rethinking the value of sewage sludge 

Researchers from the Plant Nutrition Group at ETH Zurich have been evaluating methods to develop an efficient and environmental friendly phosphate fertilizer from sewage sludge ashes. A new thermo-chemical process that extracts ...

Belly button bacteria under the microscope

(Phys.org)—Researchers have discovered which bacteria species are most commonly found in our bellybuttons, but have still not discovered what governs which species will be found on which people. These are the first published ...

Particulates are more dangerous than previously thought

Researchers at the Paul Scherrer Institute PSI have for the first time observed photochemical processes inside the smallest particles in the air. In doing so, they discovered that additional oxygen radicals that can be harmful ...

Key points in the genetically modified food debate

One of the biggest stumbling blocks to securing a massive free trade agreement between the United States and Europe is a sharp disagreement on genetically modified foods. Much of the corn, soybean, sugar beets and cotton ...

Transparent human organs allow 3-D maps at the cellular level

For the first time, researchers have managed to make intact human organs transparent. Using microscopic imaging, they revealed complex underlying structures of the transparent organs at the cellular level. The resulting organ ...

Fjords may emit as much methane as all the deep oceans globally

During heavy storms, the normally stratified layers of water in ocean fjords get mixed, which leads to oxygenation of the fjord floor. But these storm events also result in a spike in methane emissions from fjords to the ...

Two steps closer to flexible, powerful, fast bioelectronic devices

Dion Khodagholy, assistant professor of electrical engineering, is focused on developing bioelectronic devices that are not only fast, sensitive, biocompatible, soft, and flexible, but also have long-term stability in physiological ...
