Researchers confirm that waters migrating from the surface can take many tens of thousands of years to reach the water table
A team of researchers at Lawrence Livermore National Laboratory in California has confirmed that in drier regions, waters migrating from the surface can take many tens of thousands of years to reach the water table. Since such waters began their underground migration at the time of the last ice age, they hold a scientific and historical record of global climate change. Their results were reported in the inaugural issue of the electronic publication, Vadose Zone Journal www.vadosezonejournal.org, published by the Soil Science Society of America.
These scientists applied one of the largest super computers to study the effect of climate on water movement through this section underneath the surface, called the vadose zone. They used computer simulations to consider how this water chemically interacts with the rocks it migrates through. Because the type and abundance of minerals varies with changes in rock type, they can determine the chemical composition and how fast it changes at any point along the flow path of the water.

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...
