A study carried out by researchers at the Universitat Autònoma de Barcelonashows that protecting natural spaces does not prevent invasion by foreign vegetation species. Montserrat Vilà and Jordi Pujadas, researchers at the CREAF, have published the study, the first to quantify the relationship between species invasions and human activity on a regional scale, in Biological Conservation.
The introduction of foreign species is a global phenomenon which has negative effects on the conservation of native species and the integrity of ecosystems, having significant economic consequences. Invasion by these species is mainly due to human activity - agricultural work, gardening, and the movement of people or commerce in general, but this relationship had yet to be quantified by a study.
A team of researchers co-ordinated by Montserrat Vilà from the Ecological Research and Forestry Applications Centre (a university institute attached to the Autonomous University of Barcelona) has quantified the relationships between invasions by foreign species and human activity for the first time. The researchers analysed land use and various socio-economic parameters in regions in Europe and North Africa, in order to explore the opportunity to predict the abundance of alien plants based on these parameters.

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...

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...
