Dutch research has shown that marine plankton have the greatest effect on the climate in the southern hemisphere, even though the majority of plankton are found in oceans in the northern hemisphere.
Mtinkheni Gondwe used satellite observations to follow the distribution of phytoplankton in the oceans. Although the majority of plankton are found between the middle and high latitudes in the northern hemisphere, the effect of these on the climate is greatest in the southern hemisphere.
Plankton can influence the climate by producing the gas dimethyl sulphide (DMS). This gas is a source of small sulphur particles in the atmosphere, which act as condensation nuclei for the water vapour. The miniscule water drops formed in the air as a result of this, reflect the sunlight back before it reaches the Earth, causing the Earth to cool.

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...
