But scientists say human effects can be a positive, not negative, factor for life on earth
Human beings now directly influence more than three quarters of the earths landmass, according to a state-of-the-art map of the world produced by a team of scientists from the New York-based Wildlife Conservation Society (WCS) and Columbia Universitys Center for International Earth Science Information Network (CIESIN). Published in the latest issue of the scientific journal BioScience, the map should serve as a wake-up call that humans are stewards of the natural world, whether we like it or not – something that should be viewed as an opportunity, the authors say.
The map adds together influences from population density, access from roads and waterways, electrical power infrastructure, and land transformation such as urbanization and agricultural use. It reveals that 83 percent of the lands surface is under human influence, while a staggering 98 percent of the area where it is possible to grow rice, wheat or maize is directly influenced by human beings. At the same time, wide swaths of land still remain wild, including: the northern forests of Alaska, Canada and Russia; the high plateaus of Tibet and Mongolia; and much of the Amazon River Basin.

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...

Physics supports biology: Researchers from PTB have developed a model system to investigate friction phenomena with atomic precision
Friction: what you want from car brakes, otherwise rather a nuisance. In any case, it is useful to know as precisely as possible how friction phenomena arise –...
