An international team of applied scientists from Harvard, Hamamatsu Photonics, and ETH Zurich have demonstrated compact, multibeam, and multi-wavelength lasers emitting in the invisible part of the light spectrum (infrared).
Researchers at Duke University Medical Center have devised a way they might deliver the right therapy directly to tumors using special molecules, called aptamers, which specifically bind to living tumor tissue.
In structural biology, the only technique available to predict the three dimensional structure of large complex molecules in solution, such as proteins and DNA, is NMR spectroscopy. To catalyze improvements in the techniques behind these predictions, the 'eNMR' project has launched a new initiative. In September's Nature Methods the project issued an invitation to the entire biomolecular Nuclear Magnetic Resonance community to participate in a large scale test of modern computing algorithms.
Unter dem so genannten TIRF-Mikroskop werden Kalziumionen sichtbar, die durch die Zellhuelle in Muskelzellen einstroemen. Worin sich gesunde von kranken Muskelzellen unterscheiden, erscheint dank dieses neuartigen Mikroskops in einem ungekannten Licht.
Scientists at the University of Glasgow, in collaboration with colleagues from Edinburgh, Manchester, Southampton and York universities, have developed technology which will help microchip designers create future integrated circuits.
An experiment has confirmed that spinons, particle-like magnetic excitations, can be confined in a magnetic insulator similar to the way elementary quarks are confined within individual protons and neutrons.
A new understanding about nanoparticle behaviour in sewage treatment plants could improve the environmental management of nanoparticle wastes from foods, cosmetics, medicines, cleaning and personal care products.
Als Nanotechnologiestandort steht Hessen europaweit an der Spitze. Es ist unser erklaertes Ziel, Hessen zu einem Spitzenstandort der Nanomedizin zu machen, sagte Klaus-Dieter Jaeger, Abteilungsleiter Wirtschaftsfoerderung und Technologie im Hessischen Wirtschaftsministerium, am Donnerstag anlaesslich der Eroeffnung des 6. Nanotechnologieforums Hessen im Congress Park Hanau.
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.
