The ozone layer is thinning and we do not yet know to what extent future ozone losses will be affected by climate change, or what impact this will have on human health.
For this reason, the European Research Commissioner Philippe Busquin today welcomed the start of the first phase of the VINTERSOL (Validation of International Satellites and Study of Ozone Loss) campaign, composed of national and EU projects. VINTERSOL will be closely co-ordinated with the SAGE III Ozone Loss and Validation Experiment (SOLVE II), a US NASA (National Aeronautics and Space Administration) sponsored campaign. The kick-off meeting takes place in Brussels today. The joint initiative will involve 350 scientists from the European Union, Canada, Iceland, Japan, Norway, Poland, Russia, Switzerland and the United States. Aircraft, large and small balloons, ground-based instruments and satellites will be used to measure ozone and other atmospheric gases and particles. The project aims to improve understanding of Arctic ozone depletion, and at upgrading satellite observation of the ozone layer.
"This joint project is in the spirit of the 1998 European Union-United States Science and Technology Co-operation Agreement, which fosters joint scientific endeavours," said Commissioner Philippe Busquin. "It brings together researchers from around the world and aids better understanding of what happens in the ozone layer over the Arctic region, and therefore addresses global climate change and the effects on human health of overexposure to sun radiation. It will help us to meet the requirements of the Montreal Protocol on ozone-depleting substances, fine-tune our policies with sound scientific evidence and upgrade Europes role in the international scientific arena. This is a concrete illustration of the EUs intention to build a European GMES capacity (Global Monitoring for the Environment and Security)."

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
