British scientists are joining colleagues from around the world today (Thursday March 30th 2006) at Fermi National Accelerator Laboratory (Fermilab) in the USA to share the first results from a new neutrino experiment. The Main Injector Neutrino Oscillation Search (MINOS) is designed to study ghostly particles called neutrinos and in particular to study how the three different types are able to transform one into the other. In their first data release, the MINOS team has already reached the sensitivity of previous experiments and provides independent confirmation that neutrinos have mass.
Professor Jenny Thomas, from UCL, said "The first MINOS result is a totally independent confirmation of the surprising fact that neutrinos are not massless. It opens up a whole field of study to understand why this is true and what it means to our understanding of the universe."
Neutrinos are vital to our understanding of the Universe. Nature provides for three types of neutrinos, yet scientists know very little about these ghost particles, which can traverse the entire Earth without interacting with matter. But the abundance of neutrinos in the universe, produced by stars and nuclear processes, may explain how galaxies formed and why antimatter has disappeared. Originally neutrinos were thought to have no mass, but previous experiments suggested that they can oscillate between the three types - a phenomenon which is only possible if they do have mass.

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.

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...
