Researchers at the University of Colorado at Boulder have solved a major galactic mystery that may help astronomers in their quest to develop a detailed picture of the chemical evolution of the Milky Way galaxy.
Speaking at the 204th meeting of the American Astronomical Society held May 30 – June 3 in Denver, the researchers reported that the abundance of deuterium, a heavy form of hydrogen, in the Milky Way galaxy today shows a consistent pattern that can be simply explained, lifting a veil of uncertainty that has long plagued astronomers.
Research Professor Jeffrey Linsky of the CU-Boulder astrophysical and planetary sciences department and a fellow at JILA, and Senior Research Associate Brian Wood of JILA, reported the findings. JILA is a joint institute of CU-Boulder and the National Institute for Standards and Technology.

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...
