Cow power could generate electricity for millions
Converting livestock manure into a domestic renewable fuel source could generate enough electricity to meet up to three per cent of North America's entire consumption needs and lead to a significant reduction in greenhouse gas emissions (GHGs), according to US research published today.   view more (2008-07-24)

Brown Chemists Create Cancer-Detecting Nanoparticles
A team led by a Brown University chemist has created the smallest iron oxide nanoparticles to date for cancer detection by magnetic resonance imaging (MRI). The magnetic nanoparticles operate like tiny guided missiles, seeking and attaching themselves to malignant tumor cells. Once they bind, the... view more (2008-05-28)

A gas, Viagra and sex in plants - researchers at the Instituto Gulbenkian de Ci'™ncia have found a link
Viagra affects growth of the male sex organ of plants, by intensifying the effect of nitric oxide during plant fertilization. This discovery, made by the Plant Development team at the Instituto Gulbenkian de Ci'™ncia(IGC), in Portugal, will be published in Development, in June. The study, led... view more (2004-05-11)

Gloomy forecast for Nobel Direct after 3 years
Three years after patients were given Nobel Direct dental implants, the risk of the implant loosening has increased even more. A follow-up by researchers at the Sahlgrenska Academy in Sweden shows that eight per cent of the implants are lost.   view more (2007-12-21)
