By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics.
"Most climate models assume that roots are shallow -- usually within 6 feet of the surface -- and that only the soil moisture near the surface can significantly impact the climate," said Praveen Kumar, a professor of civil and environmental engineering at the University of Illinois at Urbana-Champaign. "Our research shows that it is not just the near surface, but also the deep reservoir of soil moisture that affect terrestrial heat and moisture processes in land-atmosphere interaction."
A better understanding of this interaction, Kumar said, could lead to more accurate climate models and better predictability.

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...
