New mechanism of plasmons specific for spin-polarized nanoparticles
This article experimentally shows that Co nanoparticles with a single-domain crystal structure support a plasmon resonance at approximately 280 nm with better quality than gold nanoparticle resonance in the visible. The magnetic nature of these nanoparticles suggests a new type of these plasmons.

Tracing the accretion history of supermassive black holes through X-ray variability: results from the Chandra Deep Field-South
This article studies the X-ray variability properties of distant active galactic nuclei (AGNs) in the Chandra Deep Field-South region over 17 yr, up to z ~ 4, and compare them with those predicted by models based on local samples.

Dioxygen: What Makes This Triplet Diradical Kinetically Persistent?
This article examines experimental heats of formation and enthalpies obtained from G4 calculations to find that the resonance stabilization of the two unpaired electrons in triplet O₂, relative to the unpaired electrons in two hydroxyl radicals, amounts to 100 kcal/mol.

Entropic Approach to the Detection of Crucial Events
This article establishes a clear distinction between two processes yielding anomalous diffusion and 1/ f noise. One of the processes, Aging Fractional Brownian Motion (AFBM), has been concluded to be the form of communication between the heart and the brain.
