Neue Nachwuchsgruppe am IFW Dresden

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.

New research could advance research field critical to personalized medicine

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.

A ‘fountain of youth’ for stem cells?

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.

Structural details of an environment-sensing protein complex could guide development of new drugs

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.

Accelerating with light

Sophisticated as it is, a superconducting linac is a conventional particle accelerator that, in a machine like the Next Generation Light Source (NGLS) now under study, can be used to produce superbright laser beams. The inverse is also true: powerful lasers can be used to accelerate charged particles - but in ways that are anything but conventional.

Carbon science breakthrough leads to dramatically stronger nanotube composites

No other element in the periodic table bonds to itself in an extended network with the strength of the carbon-carbon bond. This special nature of carbon, combined with the molecular perfection of single-walled nanotubes endows these nanotubes with exceptional material properties, such as very high electrical and thermal conductivity, strength, stiffness, and toughness. As a result, single-walled carbon nanotubes (SWCNTs) are the strongest material known to science. SWCNTs potentially can add incredible strength, stiffness and electrical conductivity to all kinds of composite materials. Unfortunately, they are always held together in rope form due to their extremely small dimension and van der Waals attraction and their strength can neither be exploited nor measured. However, if several SWCNTs are concentrically nested in a confined space, the sliding issue can be resolved and the SWCNTs may share the applied tensile load to realize nanometer-scale materials remarkably stronger than the individual SWCNTs.
