For many, sea-level rise is a remote and distant threat faced by people like the residents of the Tuvalu Islands in the South Pacific, where the highest point of land is only 5 meters (15 feet) above sea level and tidal floods occasionally cover their crops in seawater.
Now, however, a recently published study by researchers from The Earth Institute at Columbia University and the International Institute for Environment and Development suggests that as much as 10 percent of the worlds population is vulnerable. In particular, the authors have found that many large cities face risks posed by rising sea level and increased storm intensity.
"Urban areas have traditionally been studied in a way that separates them from their physical surroundings," says Deborah Balk, a demographer with the Center for International Earth Science Information Network (CIESIN), a member of The Earth Institute at Columbia University. "We talk about urban issues as if they occur in a spatial vacuum, but you cant address these questions without understanding the spatial dimensions."

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
