Guatemalans use a space-derived UNOSAT map
high-res satellite image of Matagalpa, showing the limits of the local water supply
United Nations-led development efforts in some of the poorest and most remote parts of the globe are being guided by images from space.
The ESA-backed UNOSAT consortium is providing an average of five new satellite-derived maps or data products to UN agencies and non-governmental organisations every week.
The poor Nicaraguan highlands municipality of Matagalpa is just one site among many where UNOSAT-supplied geographical information system (GIS) tools are being used in development projects. Here the International Strategy for Disaster Reduction (part of the UN Office for the Coordination of Humanitarian Affairs) is using space-derived relief data that identifies areas most at risk of landslides to plan safe urban expansion.

New research group at the University of Jena combines theory and experiment to demonstrate for the first time certain physical processes in a quantum vacuum
For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles...

Combining an atomically thin graphene and a boron nitride layer at a slightly rotated angle changes their electrical properties. Physicists at the University of Basel have now shown for the first time the combination with a third layer can result in new material properties also in a three-layer sandwich of carbon and boron nitride. This significantly increases the number of potential synthetic materials, report the researchers in the scientific journal Nano Letters.
Last year, researchers in the US caused a big stir when they showed that rotating two stacked graphene layers by a “magical” angle of 1.1 degrees turns...
