The discovery that an ancient light harvesting protein plays a pivotal role in the photosynthesis of green algae should help the effort to develop algae as a biofuels feedstock. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have identified the protein LHCSR as the molecular 'dimmer switch' that acts to prevent green algae from absorbing too much sunlight during photosynthesis and suffering oxidation damage as a consequence.
Is it possible to make even more compact digital memories for portable electronic devices and which consume even less energy? A team of CNRS and CEA researchers has recently demonstrated that it is feasible, thanks to a new class of materials known as multiferroics, which combine unusual electric and magnetic properties.
Genauer als jemals zuvor lassen sich Oberflaechen durch ein bisher einzigartiges Roentgenmikroskop, das NanoXAS-Mikrospektroskop, chemisch abbilden. Moeglich ist das, weil die Staerken zweier Nanosonden verknuepft werden: die der Rasterkraftmikroskopie und der Roentgenmikrospektroskopie.
The European Research Council (ERC) of the European Union has awarded prof. dr. Bert Meijer of the Eindhoven University of Technology in the Netherlands an Advanced Grant of two million Euros. The money allows Meijer to explore the area of non-covalent synthesis of functional supramolecular systems.
Researchers have developed a new method to reduce the amount of radioactive waste considerably. The approach: small beads consisting of a special polymer which 'fishes' the radioactivity out of the water.
A new generation of ultrasmall transistors and more powerful computer chips using tiny structures called semiconducting nanowires are closer to reality after a key discovery by researchers at IBM, Purdue University and the University of California at Los Angeles.
The EU ERA-NET initiative EuroNanoMed will support eight transnational research projects with EUR 17 million based on the result of its first call for proposals, which was launched in May 2009 to promote collaborative and interdisciplinary research into nanomedicine - the application of nanotechnology to health.
Ob es um die Entwicklung neuer optischer Materialien, wie etwa ultraduenne Metallfilme geht, um metallische Nanopartikel, um das Schalten mit Licht, um ultraschnelle Nanooptik, um Atomoptik in Wellenleitern, um Halbleiter-Quantenpunkte, um neuartige Lichtquellen und Interferometer oder um die Optimierung von Nano-Antennen: In der Optik, Photonik und Optolelektronik ist die Universitaet Stuttgart hervorragend aufgestellt.
In the fruit fly Drosophila, oskar mRNA, which is involved in defining the animal's body axes, is produced in the nuclei of nurse cells neighbouring the oocyte, and must be transported to the oocyte and along its entire length before being translated into protein. Scientists have now visualized the molecular mechanism that underlies this localisation process.
