Researchers in Norway have developed a chemotherapy delivery system consisting of microbubbles containing drug-loaded nanoparticles. When the researchers apply ultrasound to the microbubbles in a tumor, the microbubbles burst, releasing the nanoparticles and the chemotherapeutic drug. Researchers worldwide are trying to develop new ways to increase the success of chemotherapy for cancer, and reduce its side-effects.

Does it really help to drive an electric car if the electricity you use to charge the batteries come from a coal mine in Germany, or if the batteries were manufactured in China using coal? Researchers at the Norwegian University of Science and Technology's Industrial Ecology Programme have looked at all of the environmental costs of electric vehicles to determine the cradle-to-grave environmental footprint of building and operating these veh...

Glass fibres do everything from connecting us to the internet to enabling keyhole surgery by delivering light through medical devices such as endoscopes. But as versatile as today's fiber optics are, scientists around the world have been working to expand their capabilities by adding semiconductor core materials to the glass fibers. Now, a team of researchers has created glass fibres with single-crystal silicon-germanium cores.

The world's workshop - China - surpassed the United States as the largest emitter of greenhouse gases on Earth in 2007. But if you consider that nearly all of the products that China produces, from iPhones to tee-shirts, are exported to the rest of the world, the picture looks very different. "If you look at China's per capita consumption-based (environmental) footprint, it is small," says Diana Ivanova, a PhD candidate at Norwegian University of...
