New features may make southern sky’s Coalsack ideal for further study
Stargazers call a prominent dark black region in the Southern Hemisphere’s night sky the Coalsack. Even for naked-eye observers, the cloud of cold gas that makes up the Coalsack is hard to miss: It covers a part of the misty luminescence of the Milky Way, blocking out distant stars of our galaxy with the deep black shades that have earned the Coalsack its name.
A newly discovered aspect of the Coalsack may soon have astronomers thinking of it more like a treasure chest. At an American Astronomical Society Meeting in Nashville this week, astronomers will reveal evidence that the Coalsack has hot gases on its perimeter, a finding that means the Coalsack will likely provide many outstanding opportunities to learn more about interactions between regions of hot and cold gas, processes that are essential to star formation and distribution of the elements that make up life forms and the planets. Findings from the Coalsack may also help scientists refine their models of energy production in the galaxy.

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...
