Rare color shifting discovered in iconic Australian frog

University of Newcastle researchers have documented one of the clearest examples of iridescence ever recorded in an amphibian, revealing that the endangered green and golden bell frog (Ranoidea aurea) possesses intricate ...

Measuring iron in motion at Earth-core conditions

It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from Earth's surface, researchers from Lawrence Livermore National Laboratory (LLNL) and several ...

Tiny carbon rings enable a new form of quantum control

Quantum states can be precisely controlled with the help of tiny carbon rings measuring only a few nanometers in size. This is made possible by a class of rarely used electromagnetic dipoles called toroidal moments. Using ...

New ultrathin lens focuses light into an optical needle

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence ...
