In the quest to repair damaged DNA - a process believed crucial in combating ailments ranging from cancer to aging - antioxidant has been the Holy Grail. But findings published this week in Nature suggest oxidation isnt always the enemy.
Robert Hausinger and Timothy Henshaw
Scientists at Michigan State University, along with colleagues in England, have uncloaked a mechanism that uses oxygen to repair DNA - until now an unlikely part of the restorative recipe. Their work is published in the Sept. 12 issue of the British science journal Nature.
"This offers possibilities to anyone working in the DNA repair field who likely hasnt considered oxygenation before," said Robert Hausinger, an MSU microbiology and biochemistry professor. "The field has been so focused against it."

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...
