Mayo Clinic genomics researchers are the first to demonstrate that mixing of genetic material can occur naturally, in a living body. The researchers have discovered conditions in which pig cells and human cells can fuse together in the body to yield hybrid cells that contain genetic material from both species and carry a swine virus similar to HIV (the virus that causes AIDS) that can infect normal human cells.
While the research does not answer the question of whether this infection can cause actual disease in humans, it does provide scientists with a new way to understand how viral infections can pass from animals to humans.
"What we found was completely unexpected," says Jeffrey Platt, M.D., director of the Mayo Clinic Transplantation Biology Program. "This observation helps explain how a retrovirus can jump from one species to another -- and that may speed discovery about the origin of diseases such as AIDS and SARS. The discovery also may help explain how cells in the circulation may become part of the solid tissue." The Mayo Clinic research appears in the online Express edition of the FASEB Journal. (www.fasebj.org) published by the Federation of American Societies for Experimental Biology. The print article will appear in the March issue of the journal (volume 18, issue 3).

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...
