Coral reefs across the Caribbean have suffered a phenomenal 80% decline in their coral cover during the past three decades, reveals new research from the University of East Anglia (UEA) and the Tyndall Centre for Climate Change Research, published this week in the international online journal Science Express.
The amount of reef covered by hard corals, the main builders of reef framework, has decreased on average from 50% to just 10% in the last 25 years. Although the majority of the loss occurred in the 1980s, there is no evidence that the rate of coral loss is slowing.
“The feeling among scientists and tourists has long been that Caribbean corals are doing badly, since many people have seen reefs degrade over the years. We are the first to pull information together from across the region and put a hard figure on coral decline. The end result has surprised us. The rate of decline we found exceeds by far the well-publicised rates of loss for tropical forests”, said Toby Gardner, the lead author who compiled the data, and Dr Isabelle Côté, a specialist in tropical marine ecology in UEA’s School of Biological Sciences.

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...
