An insect †Archaeopteryx: Cretaceous amber fossil elucidates the evolution of complex host detection and ovipositor mechanisms in parasitoid woodwasps (Hymenoptera: Orussoidea)

Systematic Entomology, Volume 50, Issue 3, Page 630-645, July 2025.
We describe †Cretovelona orussopteryx n. gen. & sp. from Kachin amber. The fossil is examined with synchrotron scanning and integrated into an existing morphological data set for Orussoidea. This fossil parasitoid wasp displays a unique character combination demonstrating intermediate conditions in evolving the complex features employed in echo ...

Superhydrophobic Solution Blow Spinning PTFE–SiO2 Composite Membranes for Enhanced Liquid–Liquid Extraction

Journal of Applied Polymer Science, Volume 142, Issue 22, June 10, 2025.
Solution blow spinning PTFE‐SiO2 membrane for membrane assisted solvent extraction. ABSTRACT An ultrafine‐fibrous polytetrafluoroethylene (PTFE)–SiO2 membrane was successfully fabricated using the solution blow spinning (SBS) method. This membrane demonstrated superhydrophobicity (water contact angle > 150°) and oleophilicity (ethyl acetate contact ...

Dynamic Plasma Membrane Topography Linked With Arp2/3 Actin Network Induction During Cell Shape Change

BioEssays, Volume 47, Issue 6, June 2025.
Cell shape changes underlie animal development, physiology, and disease. The cell surface is mechanosensitive to the microenvironment and cytoskeleton activities, which generate plasma membrane topographies recognized and affected by Arp2/3 actin network induction pathways to remodel cell shape during immune cell migration, neural progenitor cell ...

UGV‐Based Precision Spraying System for Chemical Apple Blossom Thinning on Trellis Trained Canopies

Journal of Field Robotics, Volume 42, Issue 4, Page 1000-1011, June 2025.
ABSTRACT Blossom thinning is one of the key steps in apple crop load management that improves the quality of apples, reduces stress on the trees, and avoids the likelihood of biennial bearing. Conventional chemical blossom thinning such as air‐blast spraying can lead to excessive use of chemical thinner to ensure full coverage, which can also cause ...
