Researchers from Johns Hopkins University are developing a novel method of testing exhaled breath to detect infection rapidly after potential exposure to a biological warfare agent. They report their findings today at the 2005 ASM Biodefense Research Meeting.
"We want to have a tool that can help in the emergency room or first responders to triage on site so that people who are infected can get treatment first," says Joany Jackman, a researcher on the project. "Its not so hard to sample breath from many people very quickly as it is to draw blood."
When exposed to disease causing organisms, cells in the body release proteins, called cytokines, to help the immune cells identify and fight the infection. Jackman and her colleagues theorized that cytokines might work their way up through the tissue until eventually they would be exhaled through water vapor in the breath, and could be captured and identified.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
