The world’s largest and most species rich forests are changing faster than we thought. We know the Amazonian rainforests are disappearing – around a fifth has been lost to logging and cattle ranging – but University geographers have discovered that the forests are changing at a remarkable rate. Their findings suggest we still don’t understand exactly how long the rainforests can continue to be the planet’s ‘lung’ or even how they really work.
Geographers and earth scientists have just returned from a two-month field trip deep in the rainforests of Amazonian Peru with colleagues from Peru, Germany, Spain, Taiwan and Colombia. “We’re very interested in the role of tropical forests in the global carbon cycle,” said Natural Environment Research Council fellow Dr Tim Baker. “These forests store large amounts of carbon. It’s vital to understand exactly how much carbon they’re holding and how this may change over time.”
An important aim of the RAINFOR project is to show how Amazonian forests are not all the same. The team has been measuring the diameter of the same trees in over 100 plots every four to five years since the early 1980s. This enables them to calculate how much carbon is stored in the tree, and the forest as a whole, and how this has changed since the project began.

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...
