A North Carolina State University chemist has found a way to give DNA-based computing better control over logic operations. His work could lead to interfacing DNA-based computing with traditional silicon-based computing.
Nanowissenschaftler konnten Folgendes herausfinden: Waehrend des Abkuehlens werden die "Maschen" des Graphengitters gequetscht, bis zur Entlastung Falten entstehen. Umgekehrt werden die Maschen beim Aufheizen erst ordentlich auseinandergezogen, bevor die Falte wieder verschwindet.
New research has used Sendai virus to transport Quantum Dots (Qdots) into brain cancer cells and to specifically bind Qdots to epidermal growth factor receptor (EGFR) which is often over-expressed and up-regulated in tumors.
For years, biologists have been amazed by the power of gecko feet, which let these 5-ounce lizards produce an adhesive force roughly equivalent to carrying nine pounds up a wall without slipping. Now, a team of polymer scientists and a biologist at the University of Massachusetts Amherst have discovered exactly how the gecko does it, leading them to invent "Geckskin", a device that can hold 700 pounds on a smooth wall.
A team of international researchers has discovered a new type of structural anomaly, or defect, that can appear in quasicrystals, a unique material with some crystal-like properties but a more complex structure.
A mixture of current drugs and carbon nanoparticles shows potential to enhance treatment for head-and-neck cancers, especially when combined with radiation therapy, according to new research by Rice University and the University of Texas MD Anderson Cancer Center.
Researchers at Polytechnique Montreal have succeeded in changing the genetic material of cancer cells using a brand-new transfection method. This major breakthrough in nanosurgery opens the door to new medical applications, among others for the treatment of cancers.
In a research lab at Wake Forest University, biophysicist and computer scientist Samuel Cho uses graphics processing units (GPUs), the technology that makes videogame images so realistic, to simulate the inner workings of human cells.
Arbeitsschutzaspekte standen im Fokus der Tagung "Nanomaterialien: Risiken am Arbeitsplatz und verantwortungsvoller Umgang" am 12. Dezember 2011 am LGL. In den Vortraegen gingen die Referenten vor allem auf die derzeitig gueltigen Regelungen und den Umgang mit Nanomaterialien am Arbeitsplatz ein.
At the Summit on the Global Agenda 2011 in Abu Dhabi, United Arab Emirates, the World Economic Forum's Global Agenda Council on Emerging Technologies asked some of the world's leading minds within the entire GAC Network which technology trends would have the greatest impact on the state of the world in the near future.
Researchers from the NIST Center for Nanoscale Science and Technology and Sandia National Laboratories have published a detailed review of recent experimental and theoretical work highlighting the unusual physics and material science of electrical contacts to nanostructures.
