Crop microbiomes promote plant health through various mechanisms, including nutrient provisioning. However, agriculture neglected the importance of these microbiome-associated phenotypes (MAPs) in conventional management approaches originating from the Green Revolution. Green Revolution innovations, such as nitrogen fertilizers and high-yielding germplasm, supported an increase in global crop yields. Yet these advances also led to many environmental issues, including disruptions in microbially mediated nitrogen transformations that have reduced reliance on microbiomes for sustainable nitrogen acquisition. Overcoming the challenges introduced by the Green Revolution requires a shift toward ecologically informed agronomic strategies that incorporate MAPs into breeding and management decisions. Agriculture in the Anthropocene needs to mindfully manage crop microbiomes to decouple agrochemical inputs from profitable yields, minimizing the environmental repercussions of modern agriculture.

In the early 1990s, based on China's basic national conditions, Li Zhensheng put forward the concept of sustainable agricultural development that took the path of resource-conserving and high-yield agriculture. He carried out breeding explorations on the efficient use of mineral nutrients by crops and pioneered a new direction for wheat breeding with the goals of "less input, more output, environmental protection, and sustainable development", mainly focusing on improving the absorption and utilization efficiency of phosphorus and nitrogen. He has led and greatly promoted "the Second Green Revolution" in China's agriculture.

Objectives: As global warming intensifies, the healthcare industry faces a parallel need to treat climate-related illness and scrutinize our greenhouse gas emissions. Metered-dose inhaler medications for reactive airways diseases constitute a substantial portion of healthcare emissions. Metered-dose inhalers are often overprescribed, underlabeled, and lost after a few actuations in the emergency department (ED).

Driven by eutrophic conditions, AM (algal mat) proliferation is now ubiquitous in coastal areas generating significant ecological and economic impacts. The need to mitigate negative effects has prompted the exploration of removal methods, but neither the success nor the impacts on intertidal mudflats have been assessed. Limited success using a specially-adapted vessel, prompted a shift to manual removal by hand-rake at two UK (Portsmouth and Poole) and two French study sites (Brittany and Normandy).

Novel Cyanoethyl Cellulose-based Bilayer Materials for Electrowetting Displays at Low Voltage.

Electrowetting displays (EWD) still face the challenge of high driving voltages, provided by specialized driver ICs for electrowetting technologies. However, if the driving voltage is reduced to the threshold of widely used driver ICs of liquid crystal displays, it would significantly accelerate the revolution of driving ICs for EWD devices. Cyanoethyl cellulose (CEC) is utilized as a novel dielectric layer for electrowetting-on-dielectric systems and shows a large contact angle modulation, enabling low-voltage-driven wettability and device operation.
