A 20% drop in the price of distiller dried grains, or DDG, after top consumer China turned away two shipments that may contain unapproved genetically modified corn strains are "clearly a negative" for US ethanol producers which rely on the ...
This image shows a collection of vaccinating nanoparticles, which at their largest are about 1,000 times smaller than a human hair. The inset graphic is a representation of how the engineered proteins decorate a nanoparticle's surface. ...
Researchers have developed a technique for creating nanoparticles that carry two different cancer-killing drugs into the body and deliver those drugs to separate parts of the cancer cell where they will be most effective. The technique was ...

Researchers have uncovered the secret recipe to making some petunias such a rare shade of blue. The findings may help to explain and manipulate the color of other ornamental flowers, not to mention the taste of fruits and wine, say ...
Rho-associated protein kinase is an essential regulator of cytoskeletal dynamics during the process of neurite extension. However, whether Rho kinase regulates microtubule remodeling or the distribution of adhesive proteins to mediate ...

Researchers have used one of the brightest X-ray sources on the planet to map the 3-D structure of an important cellular gatekeeper known as a G protein-coupled receptor, or GPCR, in a more natural state than possible before. The new ...
Physicians in the Neonatal Intensive Care Unit in the Maxine Dunitz Children's Health Center launched a pilot study in which mothers' breast milk is analyzed to determine whether premature infants are receiving the correct amounts of ...
