Different approaches to increase the storage capacity of flash memories

There is a big demand for flash memories that can store even more data. However, it is now necessary to use new materials and technologies to improve flash memories and researchers worldwide are trying different approaches to achieve this aim. The project REALISE has developed a material and a processing technique now ready for industrial application.

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.

Sticking power: new adhesive earns patent, could find place in space

A recently patented adhesive made by Kansas State University researchers could become a staple in every astronaut's toolbox. The patent, "pH dependent adhesive peptides", covers an adhesive made from peptides -- a compound containing two or more amino acids that link together -- that increases in strength as moisture is removed.

Genes mimic Facebook workings

Scientists at the European Molecular Biology Laboratory (EMBL) and the German Cancer Research Centre (DKFZ) in Heidelberg in Germany have developed a method to uncover the combined effects of genes. The method should help scientists understand how different genes can amplify, cancel out or mask the effects of each other.
