Virtual floods modelled inside computers are an increasingly useful means for authorities to prepare for genuine river surges. With flooding classed as the worlds most costly natural hazard, an ESA project has assessed using satellite imagery to improve flood simulation models.
Flood control and management represents a major challenge for water authorities, and as the global incidence of flooding increases, it has also become a subject of concern for the global insurance industry.
The US Geological Survey estimates that flooding is the worlds most costly type of natural disaster, costing €170 billion ($200 billion) between 1991 and 1995. Last years European floods alone are reported to have caused more than €7 billion of damage.
Like everything linked to the weather, floods are difficult to predict – a few days of steady rainfall might be sufficient for a river to burst its banks.

Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
