An increased frequency of extreme precipitation events has been observed over the last 100 years in the United States. Global climate models project that similar trends may continue and even strengthen over the coming decades, due to climate change. Now, a study using computer climate and crop model simulations predicts that U.S. agricultural production losses due to excess rainfall may double in the next 30 years, resulting in an estimated $3 billion per year in damages.
Cynthia Rosenzweig and Francesco Tubiello, researchers at the NASA Goddard Institute for Space Studies and Columbia University, New York, and the other authors of this study, found that current assessments of the impacts of climate change on agriculture have not accounted for the negative impacts on crops from increased precipitation and floods. In an effort to close this information gap, the researchers modified an existing crop computer model to simulate the extent to which excess soil moisture from heavy rain might damage crop plants.
"The impacts of excess soil moisture due to increased precipitation need to be taken into account because of associated crop losses and potential financial damages," Rosenzweig said.

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...
