In nature, the strength of mother-of-pearl is a key to survival for some shellfish. Now a team at the University of South Carolina has posited an explanation for the unusual resilience that this important defensive shield shows in the face of predatory attacks.
An investigation by a group of Thai researchers has demonstrated that Caveolin-1 (Cav-1) plays an important role in the migration and invasion of human lung cancer cells and that these effects are regulated by cellular reactive oxygen species (ROS).
Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Researchers have now succeeded in developing an efficient upconversion process in nanoparticles, ensuring a broad tunability of light emission that could be used in imaging applications.
Hundertprozentige Sicherheit gibt es auf dem Gebiet der Quanteninformation, der Signaluebertragung mit einzelnen Lichtteilchen. Nun haben Wissenschaftler einen winzigen Lichtspeicher aus Diamant hergestellt, mit dem sie die Erzeugung der benoetigten einzelnen Lichtteilchen deutlich steigern konnten.
Leica Microsystems has signed an agreement with the Max Planck Society and the German Cancer Research Center for the development of the next generation of super-resolution STED (Stimulated Emission Depletion) microscopy.
One of the Advanced Grants awarded by the European Research Council (ERC) in its latest funding round has gone to Professor Herrmann Gaub, Spokesman of the Center for NanoScience (CeNS) at LMU Munich for his research project on "Designer Cellulosomes by Single Molecule Cut and Paste".
