New Molecules for a Faster Internet 94

Roland Piquepaille writes "An international team of researchers has discovered a new generation of optical molecules which interact 50% more strongly with light than any molecules ever tested. These organic molecules, known as chromophores, have been theorized by physicists at Washington State University, synthesized by chemists in China and tested for their actual optical properties by chemists in Belgium. But if they're excellent candidates for being used in optical technologies such as optical switches and Internet connections, these new materials should not be used before several years — if ever. Read more for additional details and a picture of the physicist who broke a law he established in 1999."

Nanoknives To Be Used to Cut Cells 78

Roland Piquepaille writes "American researchers have built a carbon nanotube knife. According to the National Institute of Standards and Technology (NIST), this nanoknife will be used to cut and study cells. With this new tool, scientists and biologists will be able to make 3D images of cells and tissues for electron tomography, which requires samples less than 300 nanometers thick. And as cells are usually stored in wax for dissection, the researchers plan to test their nanoknives on a block of wax later this year. But read more for additional references and a picture of this nanoknife."
