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

Researchers at the University of Ulster and Belfast City Hospital are set to launch a groundbreaking study that could offer a new insight into the prevention of prostate cancer.

The study will focus on a significant link between low levels of serious prostate cancer and the presence of soy products in the diet.

Professor Ian Rowland, from the University of Ulster said: “The incidence and mortality rate of certain cancers such as colorectal and prostate cancers, is much higher in W

A report in the open access journal BMC Psychiatry presents a new hypothesis that may explain the causes of the psychiatric disease, schizophrenia. The hypothesis hinges on glia, a special type of cell, which is important for the maintenance of the connections between brain cells. By re-examining previously published research the authors suggest that schizophrenia may be caused by a combination of defective genes, which result in deficiencies of a variety of growth factors in glia, and infection by v

Roman A. Amosov and a team of Russian scientists from the Central Institute for Geological Exploration of Non-ferrous and Noble Metals, Institute of Paleontology, Russian Academy of Sciences, and from the Institute of Microbiology, Russian Academy of Sciences, led by, have managed to simulate in the laboratory the process of precipitation of gold which in the natural geothermal wells is promoted by blue-green algae (cyanobacteriae).

For the purposes of the experiment Vladimir Orleans
