Dutch researcher Daniël van den Broek investigated bacteria which fight fungal infections in plants. Spontaneous variations in the phase of these bacteria reduce the anti-fungal protective function but increase the bacterias competitive advantage and with this their chances of survival.
Scientists worldwide are looking for biological alternatives to chemical pesticides in order to protect crops against pathogens. One of these is the use of bacteria which protect plants, for example, by producing antifungal substances. Daniël van den Broek investigated how to improve the reliability of crop protection methods that use these microorganisms.
Van den Broek studied Pseudomonas bacteria. The molecular biologist first of all isolated and described these bacteria, which are found in or on the roots of maize. Of the 214 strains isolated, 46 were found to suppress the growth of pathogenic fungi, for example those which cause black root rot. In total 43 of these 46 medicinal strains spontaneously switched between the two phases.

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...
