Guest‐Induced Activation of Multicolor Photoluminescence in Naphthalene Bisimide Liquid Crystals

Advanced Materials, EarlyView.
Supramolecular host–guest design in naphthalene bisimide liquid crystals activates charge‐transfer emission and enables continuous tuning of color (511–685 nm) and lifetime, spanning prompt fluorescence, TADF, and RTP. Electron‐rich guests and Pt(II) complexes modulate emissive states, while co‐assembled NBI complexes create an energy‐transfer cascade ...

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms

Advanced Robotics Research, EarlyView.
A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Weathering Dynamics Under Contrasting Greenland Ice Sheet Catchments

Frontiers in Earth Science, 2019
Chemical weathering dynamics in Greenland Ice Sheet (GrIS) catchments are largely unknown, due to a scarcity of field data. This paper presents the most comprehensive study to date of chemical weathering rates from four GrIS catchments of contrasting ...

Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

Advanced Science, EarlyView.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...

Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

Advanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

Reserve of ice in glaciers on the Nordenskiöld Land, Spitsbergen, and their changes over the last decades

Лëд и снег, 2019
Data on thickness and area of 16 glaciers on the Nordenskiöld Land (Svalbard) were obtained in 1999 and 2010–2013. These data were used to determine volume of the glaciers and to establish statistical local relationship between the volume V and the area ...

An Artificial Antibody‐Based Toolbox Accelerates Validation of Hidden Microproteins Encoded by the Dark Genome

Advanced Science, EarlyView.
Microproteins are hidden treasures encoded by the “dark proteome” but remain largely underexplored due to the lack of highly efficient tools. We developed a molecularly imprinted polymers (MIPs)‐based toolbox (CLAIMID) to achieve accelerated and ultrasensitive microproteins validation at multiple biological scales (single living cells, cell populations,
