Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

Advanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Ventilation of the Arctic Ocean: Mean ages and inventories of anthropogenic CO2 and CFC-11 [PDF]

, 2009
The Arctic Ocean constitutes a large body of water that is still relatively poorly surveyed because of logistical difficulties, although the importance of the Arctic Ocean for global circulation and climate is widely recognized.

Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks

Advanced Science, EarlyView.
In this study, the orange‐muscle giant abalone (Haliotis gigantea) is used as a model to identify a non‐coding SNP that disrupts the interaction between ITGA8 pre‐mRNA and the splicing factor ILF2, leading to altered ITGA8 splicing. These splicing changes promote carotenoid accumulation in abalone muscle through the regulation of tissue remodeling ...

A Cascade Recognition of Activatable Probe for Fluorescence Navigation Glioblastoma Surgery: Overcoming Blood‐Brain Barrier and Off‐Target Limitations

Advanced Science, EarlyView.
A cascade recognition of activatable probe ANG‐hCy‐MC is used for high‐precision depiction of glioblastoma (GBM) margin. This probe crosses the blood‐brain barrier (BBB) through LRP1 receptor‐mediated transport and provides excellent fluorescence signal contrast between the tumor and normal tissues, thereby enabling ultra‐selective imaging and precise ...

Arctic Ocean fresh water changes over the past 100 years and their causes [PDF]

, 2008
Recent observations show dramatic changes of the Arctic atmosphere–ice–ocean system. Here the authors demonstrate, through the analysis of a vast collection of previously unsynthesized observational data, that over the twentieth century the central ...

Bioinspired Engineering of Streamlined Skeletal Interoception: Neural Bioprinted Piezoelectric Scaffolds for Neuro‐Vascularized Bone Regeneration

Advanced Science, EarlyView.
This study develops neural bioprinted piezoelectric scaffolds which construct local “sensor‐effector” circuit, inspired by the skeletal interoception system. Upon US stimulation sensing and mechanoelectrical coupling by PLLA nanofibers, the incorporated DRG neurons effect through Ca2+ influx‐induced enhanced secretion and expression of CGRP.
