The map is not the territory, runs the famous quote, but maps do represent an unparalleled tool for emergency management. Nobody knows this better than humanitarian organisations like Médecins Sans Frontières, whose work often occurs within territories without any usable maps whatsoever.
ESA has been working in partnership with Médecins Sans Frontières (MSF) Belgium to remedy this. The result is the Medical Humanitarian Disaster Mapping Service (HUMAN). Since last year the service has been using satellite imagery to prepare on-demand maps of remote areas for humanitarian organisations. Now HUMAN has gone one better, enabling those organisations to make their own customised maps across most of Africa.
Arnold is an emergency officer at the MSF headquarters in Brussels. He recently received a call from the Congolese field team reporting new cholera cases near the city of Luebo. The immediate question is; Where is Luebo? There will soon be demands from the office, as he will have to inform his counterparts of the developing situation. But there is no detailed map of the Congo in the office library and it is too costly – and too long – to order a special reproduction of a new map when the team has no idea of the seriousness of the crisis. The need is for something quick and simple.

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
