Farmers growing genetically modified rice in field trials in China report higher crop yields, reduced pesticide use and fewer pesticide-related health problems, according to a study by researchers in China and at Rutgers University and the University of California, Davis. Results of the study will appear in the April 29 issue of the journal Science.
"This paper studies two of the four GM varieties that are now in farm-level preproduction trials, the last step before commercialization" says study co-author Carl Pray, an agriculture, food and resource economics professor at Rutgers Cook College who specializes in the economics of technology change in the agriculture of developing countries. "Farm surveys of randomly selected farm households that are cultivating the insect-resistant GM rice varieties demonstrate that when compared with households cultivating non-GM rice, small and poor farm households benefit from adopting GM rice by both higher crop yields and reduced use of pesticides, which also contributes to the improved health of farmers."
China began doing research on genetically modified agricultural crops in the 1980s. Although it has aggressively commercialized "Bt cotton," genetically modified to produce a natural pesticide against the bollworm, China has not developed any genetically modified food crops for the commercial market.

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...
