Nitrogen is central to food production, helping feed almost 40 percent of the worlds growing population, but the element also starts a cascade that moves through the atmosphere, soils, and waters, dramatically altering the environment.
In order to meet future need and preserve the environment, new strategies and opportunities for improved nitrogen management must be developed, scientists said today at the American Association for the Advancement of Science (AAAS) Annual Meeting.
The nitrogen cycle is one of the most important processes in nature for living organisms. Although nitrogen gas is relatively inert, bacteria in the soil are capable of "fixing" the nitrogen into a usable form – fertilizer – for plants. Humans and animals consume the plant material where the nitrogen has been incorporated into their system, primarily as protein.

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...
