Aptamer Engineering: Strategies for Discovering Functional Nucleic Acids for Next‐Generation Diagnostics and Biosensing

Advanced Science, Volume 13, Issue 2, 9 January 2026.
The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

Petrogenesis of Very‐Low‐Ti Basalts Returned by Chang'e‐6 From the Lunar Farside

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Lunar volcanism provides critical insights into the Moon's thermochemical evolution. We present petrological and geochemical analyses of six very‐low‐Ti (VLT) basalt fragments from Chang'e‐6 (CE6) samples. These basalts yield a Pb‐Pb age of around 2.9 Ga, representing the youngest reported VLT volcanism. They are slightly older than the low‐Ti
