Nanotechnology boosts the lifespan of medical implants

To overcome the problems associated with metallic implants, many research organizations and commercial companies have tried to develop orthopedic implants that have a bioactive surface to promote cellular adhesion and bony in-growth. Efforts have been made to create a stable fit that more closely resembles the original tissue, thus eliminating the need for additional surgery to repair the damage or gaps.

Quantum fluctuations are key in superconductors

New experiments on a recently discovered class of iron-based superconductors suggest that the ability of their electrons to conduct electricity without resistance is directly connected with the magnetic properties of those electrons.

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.

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.
