Finding someday may help treat hearing loss, neurodegenerative disorders
Selectively turning off a protein that controls the growth and division of cells could allow regeneration of the inner ears hair cells, which convert sound vibrations into nerve impulses. The discovery by a research team based at Massachusetts General Hospital (MGH) runs counter to current beliefs about these cells and could eventually lead to ways of preventing or treating hearing loss. The report will appear in the journal Science and is receiving early online release on the Science Express website at http://www.sciencexpress.org.
"These findings give us a potential stragegy for hair cell regeneration, which could have enormous implications for the treatment of hearing and balance disorders," says Zheng-Yi Chen, DPhil, of the MGH Neurology Service, the studys senior author. "It also shows that cells that have been considered incapable of regeneration – like most nerve cells – can reproduce under the right conditions, which may have applications to neurodegenerative diseases."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
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...
