Micro RNAs make genes shut up

Biologists at the University of Freiburg, Germany, around Lecturer Dr. Wolfgang Frank und Professor Dr. Ralf Reski from the Chair Plant Biotechnology have discovered that such micro RNAs also come into direct contact with genes, effectively turning off the genes in the process.

Observing metastasis in real-time

With an advanced microscopy technique, researchers headed by Frank Winkler of the Ludwig-Maximilians University (LMU) Munich have followed the different stages of metastases formation in real time. In the course of their work, they also found the processes that lead to a 'dead end' for the cancer cells, meaning that no metastases form.

Highly effective single-protein nanocapsules improve prospects for protein therapies

Proteins are the most important molecules inside our body. There are thousands of proteins in a single cell alone and they control our physiological reactions, metabolism, cellular information flow, defense mechanisms - pretty much everything. No wonder then that most human diseases are related to the malfunctioning of particular proteins. In contrast to gene therapy - where a gene is placed inside a cell to either replace a defective gene or to increase the amount of a specific gene in order to produce a higher amount of a desired protein - protein therapy works by directly delivering well-defined and precisely structured proteins into the cell to replace the dysfunctional protein. The problem with protein therapy, which limits its practical use in medicine, is the mode of delivery. Scientists have now demonstrated a general, effective, low-toxicity intracellular protein delivery system based on single-protein nanocapsules.

Shrink Nanotechnologies Forms Renewable Energy Team with Appointments of Solar Industry Veterans

Shrink Nanotechnologies, Inc., an innovative nanotechnology company developing products and licensing opportunities in the solar energy production, medical diagnostics and sensors and biotechnology research and development tools businesses, today announced the formation of its Renewable Energy Team, which is comprised of two distinguished academic and industry collaborators, Drs. Sayantani Ghosh and Roland Winston

Nanoengineering discovery could lead to enhanced electronics

Incorporation of nanomaterials with dimensions of less than 10 nm into functional devices has been hindered by the disparity between their size and the 100 nm feature sizes that can be routinely generated by lithography. Biomolecules offer a bridge between the two size regimes, with sub-10 nm dimensions, synthetic flexibility and a capability for self-recognition.

Golden ratio discovered on the nanoscale

Researchers from the Helmholtz-Zentrum Berlin fuer Materialien und Energie (HZB), in cooperation with colleagues from Oxford and Bristol Universities, as well as the Rutherford Appleton Laboratory, UK, have for the first time observed a nanoscale symmetry hidden in solid state matter.

The rise of graphene in ultra-fast photonics

A group of researchers from Singapore, led by Professor Dingyuan Tang from Nanyang Technological University and Professor Kian Ping Loh from National University of Singapore, have reported the first breakthrough in using few-layer graphene as a saturable absorber for the mode locking of lasers. Despite its prominent mechanical and electrical properties, graphene's optical response has previously been considered to be weak and featureless, so the main interests of the research community are centered on its electronics properties. But now, Tang and Loh demonstrate that graphene can be used for telecommunications applications and that its weak and universal optical response might be turned into advantages for ultrafast photonics applications.
