Stratospheric balloon launched from Antarctica’s McMurdo base

Aboard Cream, an experiment for the study of cosmic rays

A stratospheric balloon of Nasa was launched yesterday, December 16 at 1.28 a.m. Italian time from the Antarctica’s McMurdo base. The balloon raised Cream (Cosmic Ray Energetics And Mass) experiment up to 40 kilometres of height. In the experiment, coordinated by Eun Suk Seo of Maryland University, participate American universities (Maryland, Chicago, Penn State, Ohio), South Korea universities (Ewa, KyungPook) and an Italian group of Pisa, Siena, and Torino departments of the Italian Institute for Nuclear Physics (Infn), directed by Pier Simone Marrocchesi.

The balloon, following circulation of winds high quote, will sail around the ice continent for about three weeks. During this time, data of great scientific interest will be gathered. These data concern flows of charged particles of highest energy (cosmic rays) coming from Space.

Im Focus: Spider silk key to new bone-fixing composite

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.

Im Focus: Writing and deleting magnets with lasers

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...

Im Focus: Gamma-ray flashes from plasma filaments

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...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

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...
