Even as Thursday’s Salzburg Envisat Symposium discussed the increasingly prominent role of Earth Observation in disaster relief, Envisat played a key part in a multinational emergency exercise taking place hundreds of kilometres to the north.
When is a flood not a flood? For the duration of the International Humanitarian Partnership’s Triplex 2004 exercise, taking place in Norway this week, humanitarian aid groups are taking part in a scenario where the country’s southern Lake Mj?sa is in fact a flood zone in the imaginary country of ‘Innlandia’, inundated by a combination of heavy rainfall and a neglected dam that has given way.
Within the context of the exercise, 100 000 people have been affected by the disaster, with 1000 people stranded on an island – actually the real semi-island of Helg?ya - needing assistance and evacuation. In this imaginary setting, real international aid groups arrive to give help, with participants including Norway’s Directorate for Civil Protection and Emergency Planning, the United Nations High Commissioner for Refugees, the UK’s Department for International Development and the International Red Cross.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
