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.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
