n the current issue of Science, Stuart Lindsay, director of Arizona State University's Center for Single Molecule Biophysics at the Biodesign Institute, along with his colleagues, demonstrates the potential of a method in which a single-stranded ribbon of DNA is threaded through a carbon nanotube, producing voltage spikes that provide information about the passage of DNA bases as they pass through the tube - a process known as translocation.
Federal research dollars will help South Dakota State University scientists build a first-of-its-kind microscope that could ultimately help scientists at SDSU and elsewhere develop better solar cells for converting sunlight to electricity.
Atomic Force F+E and Asylum Research, the technology leader in scanning probe/atomic force microscopy (AFM/SPM) announce the first European AFM in Biology Class to be held February 23-25, 2010 at Atomic Force Corporate office in Mannheim, Germany.
Am Leibniz-Institut fuer Festkoerper- und Werkstoffforschung Dresden (IFW) wird ab 1.1.2010 eine von der Deutschen Forschungsgemeinschaft (DFG) gefoerderte Emmy Noether-Nachwuchsgruppe eingerichtet. Mit dem auf 5 Jahre angelegten Projekt sollen die Wechselwirkungen der Elektronen erforscht und simuliert werden, die bei physikalischen Phaenomenen wie Supraleitung oder Magnetismus eine wichtige Rolle spielen.
It's the ultimate goal in the treatment of cancer: tailoring a person's therapy based on his or her genetic makeup. While a lofty goal, scientists are steadily moving forward, rapidly exploiting new technologies. Researchers at Georgetown Lombardi Comprehensive Cancer Center report a significant advance in this field of research using a new chip that looks for hundreds of mutations in dozen of genes.
Transforming lead into gold is an impossible feat, but a similar type of 'alchemy' is not only possible, but cost-effective too. Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements.
Researchers from the University of Hong Kong and the Massachusetts Institute of Technology have published a study in the current issue of Cell Transplantation that explores ways to successfully keep stem cells 'forever young' during implantation by slowing their growth, differentiation and proliferation.
Denis Wirtz, Johns Hopkins University professor of chemical and biomolecular engineering and director of the Engineering in Oncology Center, has been named the Theophilus Halley Smoot Professor in the Whiting School of Engineering.
Researchers from the Fraunhofer Institute for Solar Energy Systems ISE teamed up with BASF to develop an environmentally-friendly alternative to air-conditioning systems. The team of researchers was nominated for the German Future Prize for their innovation comprising a microencapsulated latent heat storage material for construction materials.
Researchers in Japan have developed a technique to locate cancer cells by synthesizing a near-infrared light-emitting protein and then conjugating it with a therapeutic antibody to produce a probe for cancer cells.
Many mysteries remain about TCS signaling mechanisms, partly because the proteins involved are complicated and contain floppy, mobile regions that make structural analysis arduous. Researchers in Japan recently achieved a breakthrough on this front, however, by assembling a high-resolution reconstruction of the ThkA/TrrA TCS complex from Thermotoga maritima.
Half a protein is better than none, and in this case, it's way better than a whole one. A Rice University lab has discovered that dividing a particular fluorescent protein and using it as a tag is handy for analyzing the workings of live cells, particularly in the way they employ iron-sulfur clusters.
Nanoscientists at the University of Nebraska-Lincoln have received a prestigious grant to develop new magnetic materials that could help reduce global warming and the nation's dependence on foreign resources.
