Endocrine-Disrupting Effects of Disinfection Byproducts
Since 1974, more than 800 disinfection byproducts (DBPs) have been identified from disinfected drinking water, swimming pool water, wastewaters, etc. Some DBPs are recognized as contaminants of high environmental concern because they may induce many detrimental health (e.g., cancer, cytotoxicity, and genotoxicity) and/or ecological (e.g., acute toxicity and development toxicity on alga, crustacean, and fish) effects. However, the information on whether DBPs may elicit potential endocrine-disrupting effects in human and wildlife is scarce.

Agri-Environmental Indicators and Stakeholders’ Assessment of Their Quality
The degree to which economic goals have been prioritized over environmental and social objectives has caused dissatisfaction with conventional agricultural practices and stimulated the adoption of sustainable farming methods. One way to consider the multidimensionality of sustainable agriculture is to refer to indicators, more precisely, to agri-environmental indicators (AEIs).

Carbon Source and Sink in Arable Land Ecosystems
As a subsystem of terrestrial ecosystems, the arable land ecosystem is most closely related to human beings because it not only provides food, fiber, fuel and other products, but also supports and maintains the natural environment on which human beings depend for survival. An arable land ecosystem can act as either a carbon source or a sink.

Tea Tree Essential Oil in Hot Spring Water
The composite microcapsules of alginate/tea tree essential oil have an obvious antibacterial effect on microorganisms in hot spring water, while the composite microcapsules of alginate/chitosan have no antibacterial effect in hot spring water. When the concentration of the cross-linking agent is fixed, the longer the cross-linking time is (10 min > 5 min > 1 min), the longer the release equilibrium time of the essential oil in the microcapsules in the hot spring water is. When the cross-linking time is fixed, the higher the concentration of the cross-linking agent (1 M > 0.5 M > 0.1 M) and the longer the release equilibrium time of the essential oil in the microcapsules in the hot spring water is. When the concentration of the cross-linking agent and the cross-linking time are fixed, the higher the metal activity of the cross-linking agent (Ca > Zn) is and the longer the release equilibrium time of the essential oil in the microcapsules in the hot spring water is.

Biogas Potential from Slums in São Paulo
Slums are populated poor areas inside urban centers, mostly deprived of good-quality public services and exposed to inappropriate waste disposal and energy poverty. Using the organic fraction waste from these communities to generate high value-added products, including electricity, heat, and fertilizer, provides a circular bioeconomy with mitigation of greenhouse gas emissions, reducing environmental pollution and diseases.

1888 Ritter Island Tsunami
On the morning of March 13, 1888, an explosion took place on Ritter Island, a small volcanic island in the Bismarck and Solomon Seas, between New Britain and Umboi Island. This event is the largest volcanic island sector collapse in recent history. The explosion resulted in the almost complete loss of the island and generated a tsunami with runups of up to 20 meters (66 ft) that caused damage more than 600 kilometers (370 mi) away and killed anywhere between 500 and 3,000 on neighbouring islands, including scientists and explorers.

Urban Transportation Meteorological Observation
With the advantages of various advanced technologies from multiple aspects, researchers could further expand explorations on urban transportation meteorological observations. Associated theoretical studies and practical investigations are also to be carried out to provide solid scientific foundations for urban transportation disaster prevention and mitigation, for implementing the action of meteorological guarantees, and for the construction of a high-quality smart society.

Plant-Growth-Promoting Rhizobacteria (PGPR)-Based Biostimulants for Agricultural Production Systems
The application of biostimulants has been proven to be an advantageous tool and an appropriate form of management towards the effective use of natural resources, food security, and the beneficial effects on plant growth and yield. Plant-growth-promoting rhizobacteria (PGPR) are microbes connected with plant roots that can increase plant growth by different methods such as producing plant hormones and molecules to improve plant growth or providing increased mineral nutrition. They can colonize all ecological niches of roots to all stages of crop development, and they can affect plant growth and development directly by modulating plant hormone levels and enhancing nutrient acquisition such as of potassium, phosphorus, nitrogen, and essential minerals, or indirectly via reducing the inhibitory impacts of different pathogens in the forms of biocontrol parameters. Many plant-associated species such as Pseudomonas, Acinetobacter, Streptomyces, Serratia, Arthrobacter, and Rhodococcus can increase plant growth by improving plant disease resistance, synthesizing growth-stimulating plant hormones, and suppressing pathogenic microorganisms. The application of biostimulants is both an environmentally friendly practice and a promising method that can enhance the sustainability of horticultural and agricultural production systems as well as promote the quantity and quality of foods. They can also reduce the global dependence on hazardous agricultural chemicals.

UC Berkeley College of Natural Resources
The College of Natural Resources (CNR), a college of the University of California, Berkeley, is the oldest college in the UC system and home to several internationally top-ranked programs. CNR's Department of Agriculture & Economics is considered to be one of the most prestigious schools in agricultural economics in the world, ranking #1 according to the Journal of Agricultural and Applied Economics, #1 by the Chronicle of Higher Education, #1 by Perry for its Ph.D. programs and in International Trade, #1 by the National Research Council in Agricultural & Resource Economics, and #1 by U.S. News in Environmental/Environmental Health. In environmental disciplines, QS World Rankings recognizes the University of California, Berkeley, as the world's leading university in Environmental Studies with 100 points in Academic Reputation. U.S. News also ranks it as the best global university for environment and ecology. A study of AJAE authors and their university affiliations found it to have the highest number of pages per research faculty member. Established in 1868 as the College of Agriculture under the federal Morrill Land-Grant Acts, CNR is the first state-run Agricultural Experiment Station. The college is home to four academic departments: Agriculture and Resource Economics; Environmental Science, Policy, and Management; Nutritional Sciences and Toxicology; and Plant and Microbial Biology, and one interdisciplinary program, Energy and Resources Group. Faculty include 40 Fulbright Fellows, 30 American Association for the Advancement of Science Fellows, 19 National Academy of Sciences members, 12 Guggenheim Fellows, 9 American Academy of Arts and Sciences members, 7 MacArthur Fellows, 4 Nobel Laureates, 3 Wolf Prize winners, and 2 World Food Prize winners. The Dean of the College is Prof. David Ackerly.
