A Chirality‐Converted Bacteriolytic Dodecapeptide Regulates Vibrio‐Induced Polymicrobial Infection and Ameliorates Invasion‐Associated Gut Microbiota Disequilibrium

Advanced Science, EarlyView.
Multidrug‐resistant Vibrio infections are rising rapidly and threaten coastal populations worldwide. This study introduces D‐zp37, a chirality‐engineered antimicrobial peptide with exceptional potency against resistant Vibrio species. D‐zp37 kills planktonic cells, blocks mixed‐species biofilms, disrupts essential bacterial stress responses, and shows ...

Enhanced Intracellular Stability and Translation Efficiency of mRNA Drugs by a 2‐arm mRNA Platform

Advanced Science, EarlyView.
We constructed a 2‐arm mRNA, characterized by a unique topology formed through the dimerization of two mRNA 3’ tails. The 2‐arm mRNA improves 3’ tail stability and resistance to nuclease degradation, resulting in an intracellular half‐life of up to 65 h. This method substantially enhances the translation capacity of mRNA drugs.

The Effects of Logarithmic Spiral in Art Works

, 2021
application/pdf図形を回転するとその軌跡は円となるが、等しい倍率で拡大もしくは縮小しながら回転するとその軌跡は螺旋となる。正方形の黄金比を用いた回転を基本として様々な分数の正多角形の外心を中心としてその外角の角度分を、黄金比率の割合で拡大しながら回転させてその軌跡の円弧を繋げていった結果、黄金角である約137.5°に近い外角を持ち、分母・分子が１つ飛びのフィボナッチ数で現わされる正８／３角形、正１３／５角形が最もバランスの良い効果的な現れ方をすることをこれまでに確かめた。また ...

Allosteric DNAzyme‐Enabled Sensitive and Multiplex Detection of Biomarkers for Rapid Diagnosis of Urinary Tract Infections

Advanced Science, EarlyView.
A catalytic allosteric DNAzyme assay (SMART) is developed by engineering DNAzyme into a unimolecular biosensor, enabling highly sensitive and multiplex detection of small molecules and nucleic acids. SMART enables extraction‐free, one‐pot, one‐step, isothermal, and cost‐effective detection of biological markers, achieving >95% accuracy for rapid ...

Golden spiral or Fibonacci spiral: Which is more beautiful and why?

i-Perception
Spirals, with their widespread presence in both nature and culture, are universally admired. Although there are different types, such as the Archimedean, logarithmic, and golden spirals, they are indiscriminately considered as beautiful.
