Four scientists from the National Center for Atmospheric Research (NCAR) are studying the chemistry of sulfur and nitrogen in the air above Antarctica. The investigation will help them understand the continents chemical processes better, as well as refine scientists interpretations of ice cores, which provide information on past climates.
The expedition, which runs through January 4, is part of the Antarctic Tropospheric Chemistry Investigation (ANTCI), a four-year program funded by NCARs primary sponsor, the National Science Foundation. Along with NCAR, 10 universities and federal laboratories are participating in the investigation.
"The atmosphere of Antarctica is probably the least explored part of the lower atmosphere on the planet right now. This is the first time people have looked at any of these chemical processes in this environment," says Lee Mauldin, a chemist from NCAR and one of the projects co-investigators.

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...
