Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Natural Variation of COLD and CATECHINS REGULATOR 1 Coordinately Fine‐Tunes Cold Tolerance and Tea Quality in Tea Plants

Advanced Science, EarlyView.
Multi‐trait genome‐wide association mapping identifies a central hub regulator, COLD AND CATECHINS REGULATOR 1 (CCR1), and its excellent natural allele variation, coordinately enhancing cold tolerance and promoting catechins biosyntheis. CsCCR1 interacts with CsCBF1/3 and is transcriptionally activated by CsLUX and CsKUA1 to promote catechins ...

Hypoxia Exacerbates Inflammatory Acute Lung Injury via the Toll-Like Receptor 4 Signaling Pathway

Frontiers in Immunology, 2018
Acute lung injury (ALI) is characterized by non-cardiogenic diffuse alveolar damage and often leads to a lethal consequence, particularly when hypoxia coexists.

Multi‐tissue Metabolic GWAS and Drought‐Responsive Multi‐omics Reveal the Genetic Basis of the Quinoa Metabolome

Advanced Science, EarlyView.
A multi‐omics framework combining multitissue genome‐wide association studies, metabolomics, transcriptomics, proteomics, and functional validation uncovers the genetic basis of specialized metabolism in quinoa. The study identifies hundreds of metabolite‐associated loci, prioritizes candidate genes for saponin, betalain, and flavonoid biosynthesis ...

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Altitude hypoxia and hypoxemia: pathogenesis and management

Signal Transduction and Targeted Therapy
At high altitudes, which typically exceed 2500 m, approximately 80 million people reside permanently, with over a million visitors annually. The primary effect of high altitude is hypobaric hypoxia, which leads to decreased oxygen availability and a ...

Red Blood Cells as Endogenous Biotweezers for Optical Micromanipulation In Vivo

Advanced Science, EarlyView.
By synergistically integrating the long‐distance manipulation fiber probe (LDMFP) and endogenous red blood cells (RBCs) as biocompatible optical elements, a natural RBC biotweezer was developed for the desired microparticle manipulation and immune cell activation within living vasculature, which might offer an alternative tool for intravital optical ...
