Farmers who plant more crops, increase irrigation coverage and till the land less can have a profound effect on climate.
Climate scientists from Lawrence Livermore National Laboratory found that models that included recent changes in agricultural practices, such as more irrigation, higher yielding crops, and less tillage, predicted lower temperatures than models that ignored these factors.
“Nearly all models used to predict climate changes either ignore agriculture altogether or assume that farmers behave the same way through time,” said David Lobell, the lead author on a paper appearing in the March 23 issue of the journal Geophysical Research Letters. “In reality, farmers are changing rapidly in response to new technologies, growth in demand and other factors. This study suggests that these changes may have important cooling effects, especially at local scales.”

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...
