A Very-High-Energy Gamma-Ray View of the Transient Sky
UniverseThe development of the latest generation of Imaging Atmospheric Cherenkov Telescopes (IACTs) over recent decades has led to the discovery of new extreme astrophysical phenomena in the very-high-energy (VHE, E > 100 GeV) gamma-ray regime.

Bidirectional Soft Catalysts for Improved Power Performance of Li‐S Batteries
Advanced Science, EarlyView.A soft polymer‐metal catalyst is integrated into the binder to create a catalytically active microenvironment that accelerates bidirectional sulfur redox kinetics in lithium‐sulfur batteries. A model polyvinyl alcohol‐Cu catalyst enables high areal capacities at demanding current densities and stable cycling in pouch‐cell prototypes at 0.5 C, achieving

Prospects for Observing Astrophysical Transients with Gigaelectronvolt Neutrinos
The Astrophysical JournalAlthough Cherenkov detectors of high-energy neutrinos in ice and water are often optimized to detect teraelectronvolt–petaelectronvolt neutrinos, they may also be sensitive to transient neutrino sources in the 1–100 GeV energy range.

Magnetic Water Cleaning of Estrogens via Tight yet Dynamic Binding to Nanoparticles
Advanced Science, EarlyView.Micropollution is one of the big challenges humanity faces with estrogen hormones being emerging pollutants of concern. Here, a supramolecular design strategy is presented that generates a simple nano‐adsorbent material to magnetically remove low‐concentrated estrogens from water.

Challenging Classical Paradigms: Recurrent Nova M31N 2017-01e, a BeWD System in M31?
The Astrophysical JournalM31N 2017-01e is the second-fastest recurrent nova known, with a recurrence period of 2.5 yr in the Andromeda galaxy (M31). This system exhibits a unique combination of properties: a low outburst amplitude (∼3 mag), starkly contrasting with known ...

The Narrow Emission Lines of the Very Fast Nova V1721 Aquilae
Research Notes of the AASAbstract Infrared spectroscopy, from 12 days after discovery, is presented for the very fast nova V1721 Aquilae. The emission line spectrum, unlike the one present shortly after outburst, is dominated by narrow lines (FWHM ≈ 700 km s −1 ) that include H ...
