View ArticleHeart of an exploded star observed in 3-D
Supernovas—the violent endings of the brief yet brilliant lives of massive stars—are among the most cataclysmic events in the cosmos. Though supernovas mark the death of stars, they also trigger the...
View ArticleUnique noise signatures from single molecules interacting with carbon...
Noise is low-frequency random fluctuation that occurs in many systems, including electronics, environments, and organisms. Noise can obscure signals, so it is often removed from electronics and radio...
View ArticleCarbon displays quantum effects
Chemists at Ruhr-Universität Bochum have found evidence that carbon atoms cannot only behave like particles but also like waves. This quantum-mechanical property is well-known for light particles such...
View ArticleAntiaromatic molecule displays record electrical conductance
Researchers demonstrate high electrical conductance for an antiaromatic nickel complex—an order of magnitude higher than for a similar aromatic complex. Since the conductance is also tunable by...
