Decoding Quantum Chaos with a Single Scramblon

A combined experiment/theory study using solid-state NMR on a powder of adamantane demonstrates that quantum chaos in a many-body system can be captured by a single scramblon mode. By applying scramblon theory to disentangle intrinsic chaotic scrambling from imperfections in time reversal, researchers extract a quantum Lyapunov exponent and a universal decay parameter, supporting a universal, simple description of chaotic dynamics that could bridge tabletop quantum experiments with holographic gravity concepts.

MRI Technology Reveals Secrets of Ancient Roman Harbor Structures

Researchers have used NMR methods, similar to MRI technology, to analyze rare wooden structures from an ancient Roman harbor discovered in Naples, Italy. These non-invasive techniques allow for detailed examination of the wood's structure and preservation without damaging the samples, which have been preserved by an aquifer for centuries. The study, published in Physical Chemistry Chemical Physics, highlights the potential of NMR in archaeology and other fields, with future applications expected to expand as the technology becomes more portable and affordable.

RNA structure dictates cellular function.

RNA conformational propensities play a crucial role in determining cellular activity, according to a review published in Nature Reviews Molecular Cell Biology. The authors highlight the importance of understanding RNA structural dynamics and the use of techniques such as NMR to study RNA conformational ensembles. They also discuss the potential for targeting RNA structures in drug discovery.
