15Nitrogen uptake from shallow- versus deep-rooted plants in multi-species mixtures and monoculture grassland [PDF]
, 2010 Only few studies have explored the importance of functional diversity in temperate agricultural grasslands in relation to nitrogen (N) uptake. This study investigates the consequence of growing deep-rooted plants together with grass-clover mixtures in ...

β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma
Advanced Science, EarlyView.β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...

Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance
Advanced Science, EarlyView.This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...

A messenger molecule governs interdependency in an evolved Pseudomonas aeruginosa biofilm community [PDF]
, 2011 Biofilm populations are known to harbor great diversity, but the importance of this diversity is not fully understood. A likely contributor to this variation is the second messenger molecule cyclic-di-GMP: low levels associate with a planktonic lifestyle

Monoculture of Leafcutter Ant Gardens
PLoS ONE, 2010 Antecedentes Las hormigas cortadoras de hojas dependen del cultivo de hongos simbióticos de Attamyces para la alimentación, que se cree que son cultivados por las hormigas en monocultivos clonales de una sola cepa a lo largo de cientos a miles de jardines dentro de un nido cortador de hojas.

Advanced Science, EarlyView.This study develops a 3D co‐culture and co‐differentiation system for porcine muscle stem cells (pMuSCs) and mesenchymal stem cells (pMSCs) on edible starch‐based scaffolds. The system simultaneously generates myotubes and adipocytes without using serum or chemical inducers.
