’Life on the bubble’
A team of researchers, led by an environmental engineer at Washington University in St. Louis, has applied a molecular approach to identify the biological particles in aerosol responsible for making employees of a Colorado hospital therapeutic pool ill. They found: when the bubble bursts, the bacteria disperse, and lifeguards get pneumonia-like symptoms.
Lars Angenent, Ph.D., Washington University assistant professor of chemical engineering, and collaborators from San Diego State University and the University of Colorado, took what is known as a molecular survey of a common gene found in all life forms, 16 S ribosomal RNA (rRNA) gene, by cloning the different forms, sequencing them, and making evolutionary-distance trees, or phylogenetic trees. They then were able to match the genetic sequence of the bacterium Mycobacterium avium to the same bacterium found in the lungs of nine lifeguards who had become ill with hypersensitivity pneumonitis, a lung condition that mimics pneumonia symptoms.

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...
