The Effect of Synthetic Cow Urine on Microorganisms and Their Potential Phosphorus Mining Activity in Rhizosphere and Bulk Soil

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 69-80, February 2026.
ABSTRACT Background and aims Soil microbes adapt to varying nutrient inputs by modifying their utilization strategies, with root exudates and animal urine serving as key carbon (C) and nutrient sources in grasslands. Nonetheless, the specific mechanisms by which cow urine and root exudates influence microbial community and resource utilization remain ...

A Degradable Device for Sustainable Capillary Blood Sampling

Advanced Materials Technologies, Volume 11, Issue 2, 22 January 2026.
The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...

Stacked scattering: The key to bright flowers lies in the mesophyll

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise The coloration of flowers is caused by wavelength‐selective absorption by pigments and scattering of light by floral structures. Although the molecular, physiological, and chemical properties of floral pigments have been studied in considerable detail, how floral structures contribute to the visual signal remains largely unknown.

Aquaporin‐4 and caveolin‐1 as mediators of fibrinogen‐driven cerebrovascular pathology in cerebral amyloid angiopathy

Alzheimer's &Dementia, Volume 22, Issue 1, January 2026.
Abstract INTRODUCTION Cerebral amyloid angiopathy (CAA), marked by amyloid beta (Aβ) accumulation in perivascular spaces (PVSs), contributes to vascular injury and inflammation in Alzheimer's disease. The mechanisms underlying CAA‐related vascular pathology remain unclear.
