Scientists at Melbournes Howard Florey Institute have uncovered a clue about the causes of dementia in Huntingtons disease, one of the diseases symptoms, by showing that mice susceptible to Huntingtons disease have problems with learning and memory before the diseases typical movement problems appear.
The Florey scientists also discovered that in Huntingtons diseased brains, information processing between neurons is disrupted, but the neurons do not die, which means the brain may respond to new anti-dementia drugs that can restore memory.
Huntingtons disease is an incurable, inherited disorder of the nervous system that affects specific brain regions and inevitably leads to death. Symptoms range from disrupted control of movements and thought processes, and emotional problems. These include: jerky arm or leg movements; difficulties with speech, swallowing, concentration, memory and learning; and depression and personality changes.

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...
