Clue to how virus avoids immune system activity may lead to new treatment strategy
Massachusetts General Hospital (MGH) researchers may have provided another clue to the mystery of how HIV, the virus that causes AIDS, evades the defenses of the immune system. In the May issue of the Journal of Virology, a team from the Partners AIDS Research Center at MGH describes finding how a key protein that helps the virus enter its target T helper cells may also keep away the T killer cells that should destroy HIV-infected cells.
“One of the big questions in understanding HIV is why we can see immune responses that are effective in the test tube but do not eradicate the virus in the infected patient,” says Mark Poznansky, MD, PhD, of the Partners AIDS Research Center (PARC) and the MGH Infectious Disease Unit, the paper’s senior author. “We have identified a potential new mechanism by which pathogens can repel immune cells and thereby evade the immune system.”

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...
