Study analyses the possibilities and bottlenecks for regulating nanomaterials with uncertain risks

The study examines the possibilities and limitations for such regulation under existing legislation covering the environment, consumer protection and occupational health and safety, given the uncertain risks attached to the use of nanomaterials. The central research question is which powers authorities hold to regulate production, processing, use and the waste phase of nanomaterials (and products containing them) and the obligations that companies have to assure the safety of man and the environment.

Electro-osmotic pump simplifies home diagnostics

Researchers in Sweden have invented an improved pump, called an electroosmotic pump, which can be placed in a "microfluidic chip". Such chips, sometimes called "lab-on-a-chip" devices, contain miniaturized versions of the beakers and test tubes found in chemistry laboratories interconnected by tiny pipes. Rather than using moving parts, the new pump moves fluids in these pipes via an electric current. The fluids to be pumped can be biological samples such as blood, urine or saliva for medical devices.

Neutron analysis yields insight into bacteria for solar energy

Structural studies of some of nature's most efficient light-harvesting systems are lighting the way for new generations of biologically inspired solar cell devices. Researchers from Washington University in St. Louis and the Department of Energy's Oak Ridge National Laboratory used small-angle neutron scattering to analyze the structure of chlorosomes in green photosynthetic bacteria.
