Intergovernmental organisation urges scientists to present a unified coherent vision for large, expensive projects
The OECD Global Science Forum has developed findings and recommendations regarding future large projects in astronomy. Some of the recommendations are directed towards the international scientific community, others pertain more to the work of government funding agencies. Among the conclusions are: the need for a globally-coordinated scientific vision of the most important big projects for the next 20 years, greater international cooperation in the development of key technologies (such as large arrays of sensors), and the establishment of closer links between planning processes for space-and ground-based facilities. The report is based on discussions at two workshops that were attended by policymakers and scientists.
Astronomers have made enormous progress in the past few decades, developing a convincing model of the origin, evolution and distribution of the visible matter in the Universe, from asteroids and planets to the large-scale structure of clusters of galaxies. But the model fails to explain the composition or origin of some 96% of the contents of the Universe (the enigmatic "dark matter" and "dark energy") and does not explain the origin or distribution of life. Solving these mysteries will require costly new projects such as giant optical and radio telescopes which must be organised and financed on a multi-national basis. As the field of astronomy enters a new scientific and organisational era, the OECD report challenges researchers and administrators to coordinate, plan, administer and finance the large projects and programmes that will be needed during the coming decades.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
