Parisa Ariyas accidental discovery of the power of bioaerosols to generate rapid and dramatic chemical reactions may change – at the very least alter – the course of climate science.
Ariya, a professor at McGill Universitys Department of Atmospheric and Oceanic Sciences, in Montreal (Canada), first made her observation in August 2001, after one of her postdoctoral fellows forgot to close the valve sealing the reaction chamber where an organic compound (containing carbon, oxygen and/or hydrogen) was reacting with ozone (the form of oxygen in the stratosphere that filters out ultraviolet radiation).
By Monday, the organic compound was gone, and several new peaks in the frequency regions for carbohydrates and proteins were found. A sludge had formed on the glass walls of the chamber. What was it? Ariya deduced that airborne micro-organisms in the laboratory had found their way into the chamber, consumed the organic compound and produced new aerosols in their reaction both with the compound and the ozone.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
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...
