Dutch researcher Chris Molenaar has made the rapid movements of proteins, DNA and RNA molecules visible in living cells. With this technique researchers can study the dynamics of biomolecules in their natural environment.
Molenaar developed a method which makes it possible to follow the movements of RNA molecules in living cells. The researcher also made the movements and interactions between proteins in living cells visible with the aid of the revolutionary "Green Fluorescent Protein".
Much of the present knowledge about molecular compositions of the cell and the mechanisms in which biomolecules such as DNA, RNA and proteins play a role, is based on experiments in tests tubes with biomolecules isolated from cells. However, with these molecules it is difficult to simulate the behaviour in a living cell. Dynamic processes in the cell can only be understood with living cell microscopy.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...

In an article that appears in the journal “Review of Modern Physics”, researchers at the Laboratory for Attosecond Physics (LAP) assess the current state of the field of ultrafast physics and consider its implications for future technologies.
Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort...
