Florida Tech researchers diagnose coral disease

Researchers use mapping technique on Caribbean coral

Marine diseases are killing coral populations all over the world, threatening the livelihoods of millions of people who depend on reefs for food and protection from storms. Are these diseases new and unprecedented infections, or do they erupt from the stresses of environmental change?

Florida Institute of Technology biologist Robert van Woesik and his former student Erinn Muller—now a researcher at the Mote Marine Lab in Sarasota, Fla.—used a mapping technique to examine disease clustering and determine what might have caused the recent increase of coral diseases in the Caribbean. Their results appear in the October 9 issue of Global Change Biology.

Public health officials have been mapping diseases since the first outbreak of cholera in London in 1854. Mapping provides clues about the origin of diseases and how rapidly diseases can spread. According to Muller, "When diseases cluster they are usually contagious and are spreading rapidly. When they don't cluster, environmental stress is usually the cause."

Muller and van Woesik mapped the clustering of three coral diseases in the Caribbean and concluded that they are stress-related rather than contagious. "These coral diseases in the Caribbean are likely caused by stress," said van Woesik, "and that stress is the warming seas that are the result of climate change." The researchers suspect the corals' immune systems are compromised by increasing water temperatures, making them more susceptible to infection.

"We more easily catch a cold when we are stressed, and corals are likewise responding to stress by getting sick," said van Woesik. "The ocean will continue to warm, increasing the likelihood of coral diseases."

Im Focus: Flexible proximity sensor creates smart surfaces

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...

Im Focus: Manipulating Electron Spins Without Loss of Information

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...

Im Focus: The proton precisely weighted

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...
