Why would an uneven coating of gold on a silica surface excite any interest, much less earn cover-story honors in a respected scientific journal?

This uneven coating – nanoparticles of gold in a layer that changes from very dense to very sparse across a surface of selected molecules – will allow improvements in a wide range of processes and devices. And it’s the decreasing concentration of the coating and overlaying particles, the designed-in gradient, that has chemical engineers and ph

Burning eyes, burning lungs, skin rashes and other symptoms of illness have been found in a study of residents living near land fertilized with Class B biosolids, a byproduct of the human waste treatment process.

This study is the first linking adverse health effects in humans to the land application of Class B biosolids to be published in a medical journal. It was co-authored by David Lewis, a UGA research microbiologist also affiliated with the U.S. Environmental Protection Agency (EPA)&#

A team of researchers from The Scripps Research Institute (TSRI) has discovered a way to use adult bone marrow stem cells to form new blood vessels in the eye or to deliver chemicals that will prevent the abnormal formation of new vessels.

This technique, which involves injecting the stem cells into the eye, could potentially be used to stimulate vessel growth and address inherited degenerations of the retina in the first instance, and in the second, to treat ocular diseases resulting from

Optical properties could prove useful in biomedical, nanoelectronic applications

Add fluorescence to the growing list of unique physical properties associated with carbon nanotubes — the ultrasmall, ultrastrong wunderkind of the fullerene family of carbon molecules.

In research detailed in the current issue of Science magazine, a team of Rice University chemists led by fullerene discoverer and Nobel laureate Richard Smalley describes the first observations of fluorescence

The Department of Nutrition and Bromatology of the Faculty of Pharmacy of Gasteiz, University of the Basque Country, is studying the action mechanism of fluoxetine in genetically fattened rats (Zucker fa/fa). Due to fluoxetine, those rats eat 50 % less. Therefore, the bodies put on less weight and the size of different fat tissues is reduced.
Antidepressants of the type of fluoxetine reduce appetite. More exactly, fluoxetine affects on neuropeptides that regulate appetite. Hence, it is believed

You are less likely to have allergies if:
you have older siblings (especially brothers);
you rarely washed your face and hands as a child;
you have had gastric infections with microorganisms that originated in faeces;
you were brought up on a farm with animals;
