A General Strategy for the Synthesis of Jerangolids Enabled by π‐allyl Stille Coupling

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
A general strategy for the synthesis of jerangolids is established, featuring a late‐stage π‐allyl Stille coupling of two advanced, highly customizable building blocks to form the skipped diene core. The approach provides access to all naturally occurring jerangolids, including jerangolid H, whose configuration is confirmed by NMR analysis.

Listening to Bryde's Whales With an Island Seismometer: Low‐Frequency Call Detection and Seasonal Patterns Revealed by Deep Learning

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Bryde's whales form a major coastal aggregation in the Beibu Gulf, China. Using 1 year of continuous island‐based seismic recordings from Xieyang Island, we established a large labeled data set of coastal Bryde's whale calls with more than 1.7 million samples.

On the Temporal Variability of Precipitation in Iraq: Arid‐Wet Years and Extreme Events

International Journal of Climatology, Volume 46, Issue 7, 15 June 2026.
Daily and monthly precipitation data in Iraq display high seasonal to interdecadal variability, with arid and wet years that have very distinct seasonal cycles. Monthly rainfall is significantly correlated with the Indian Ocean Dipole. Extreme events are identified and classified as belonging to four different weather patterns, allowing to obtain daily

Robust Ag@Au Core–Shell Nanowire Networks: Chemical and Thermal Stabilities Under Harsh Conditions for Transparent Conductive Electrodes

Advanced Energy and Sustainability Research, Volume 7, Issue 6, June 2026.
Ultrathin, conformal Au shells are epitaxially grown on the surfaces of high‐aspect‐ratio Ag nanowires (NWs), which act as conductive, robust, and chemically inert barriers, effectively protecting the Ag core while preserving the conductive network.

Phylogeny of the Electric Rays of the Family Narcinidae (Gill, 1862): Systematic Review and Evidence of the Dispersal Routes to America

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The family Narcinidae has a cosmopolitan distribution; however, its systematic composition and phylogenetic position within Torpediniformes remain poorly understood. This study evaluates the evolutionary and biogeographic history of the family Narcinidae and investigates its distribution patterns using molecular systematics.
