Bradoriids and the Cambrian Diversification
Bradoriids, among the earliest arthropods to appear in the fossil record, are extinct, ostracod-like bivalved forms that ranged from the early Cambrian to the Middle Ordovician. Bradoriids are notable for having appeared in the Cambrian fossil record before the earliest trilobites, and considering their rapid ascent to high genus-level diversity, provide key data for our understanding of the evolutionary dynamics of the Cambrian Explosion. This paper presents a broad review of bradoriid paleobiology.

Circular Carbon Economy (CCE)
The circular carbon economy (CCE) system achieves a balance by closing the carbon circle, capturing CO2emissions, and using them economically after their initial linear use. This approach differs in that it does not focus solely on reducing or avoiding the increase in the amounts of carbon. The steady increase in carbon dioxide levels requires increased effort to mitigate their impact.

Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 99 million years old, during the earliest part of the Cenomanian age of the Late Cretaceous. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected.

MTBE and BTEX in Wetlands
Hydrocarbon contamination of water resources is a global issue. These compounds are generated and discharged into the environment in industrial areas from chemical and petrochemical plants, oil refineries, power plants, and so forth. Fuel hydrocarbons, namely, BTEX (benzene, toluene, ethylbenzene, and xylenes) and MTBE (methyl tert-butyl ether), are commonly found in groundwater, posing environmental and health risks to humans and ecosystems. Nature-based technologies represent an alternative solution, providing high eciency, an environmentally friendly character, simple operation, and cost eciency, which are characteristics particularly desired by the international petroleum industry. This entry discusses the use of the green technology of constructed wetlands to remediate water polluted with hydrocarbons. Although the number of related international experiences and studies is limited, the article presents the latest developments of wetland technolog for the removal of MTBE and benzene-BTEX. The discussion includes the overall eciency of the di erent wetland types that have been tested and used, the main transformation and removal processes that regulate the fate of BTEX and MTBE in constructed wetlands, and the potential for future investigations.

Adoption Pathways for DC Power Distribution in Buildings
Driven by the proliferation of DC energy sources and DC end-use devices (e.g., photovoltaics, battery storage, solid-state lighting, and consumer electronics), DC power distribution in buildings has recently emerged as a path to improved efficiency, resilience, and cost savings in the transitioning building sector. Despite these important benefits, there are several technological and market barriers impeding the development of DC distribution, which have kept this technology at the demonstration phase.

Taupo Volcanic Zone
The Taupō Volcanic Zone (TVZ) is a volcanic area in the North Island of New Zealand that has been active for the past two million years and is still highly active. Mount Ruapehu marks its south-western end and the zone runs north-eastward through the Taupo and Rotorua areas and offshore into the Bay of Plenty. It is part of the larger Central Volcanic Region that extends further westward through the western Bay of Plenty to the eastern side of the Coromandel Peninsula and has been active for four million years. The Taupo Volcanic Zone is widening east–west at the rate of about 8 mm per year. It is named after Lake Taupo, the flooded caldera of the largest volcano in the zone, the Taupo Volcano.

Japan Median Tectonic Line
Japan Median Tectonic Line (中央構造線, Chūō Kōzō Sen), also Median Tectonic Line (MTL), is Japan's longest fault system. The MTL begins near Ibaraki Prefecture, where it connects with the Itoigawa-Shizuoka Tectonic Line (ISTL) and the Fossa Magna. It runs parallel to Japan's volcanic arc, passing through central Honshū to near Nagoya, through Mikawa Bay, then through the Inland Sea from the Kii Channel and Naruto Strait to Shikoku along the Sadamisaki Peninsula and the Bungo Channel and Hōyo Strait to Kyūshū. The sense of motion on the MTL is right-lateral strike-slip, at a rate of about 5–10 mm/yr. This sense of motion is consistent with the direction of oblique convergence at the Nankai Trough. The rate of motion on the MTL is much less than the rate of convergence at the plate boundary, making it difficult to distinguish the motion on the MTL from interseismic elastic straining in GPS data.

Bacteriophages in Agriculture
Bacteriophages, more commonly referred to as phages, are a class of viruses discovered for their bactericidal effects even before the discovery of penicillin and other antibiotics. An increasingly popular alternative to antibiotics is bacteriophages to control bacterial diseases. Their unique bactericidal properties make them an ideal alternative to antibiotics, as many countries begin to restrict the usage of antibiotics in agriculture. The recent evidence from within the past decade on the efficacy of phage therapy on common foodborne pathogens are analyzed, namely, Escherica coli, Staphylococcus aureus, Salmonella spp., and Campylobacter jejuni.

Epithelial Cells in Environmental-Associated Airway Diseases
People are exposed to contaminants through the respiratory tract and skin; they first reach the bloodstream and, subsequently, the organs, causing more or less serious damage to health. Thus, the effects of atmospheric pollution affect the respiratory tract with acute symptoms and the circulatory system with cardiovascular events, leading to hospitalizations and mortality. In addition to the acute effects, long-term effects can also be had, including an alteration of lung function in adults, children, and adolescents. Specifically, in children and adolescents, chronic exposure to air pollution is associated with a reduction in forced vital capacity (FVC), which correlates with age and can be interpreted as a reduction in the lung growth and respiratory function of the lower airways. Children, together with elderly persons, are the most sensitive subjects to environmental pollution; to these are added subjects with chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). Emerging contaminants induce pulmonary toxicity by promoting an inflammatory response in lung epithelial cells.
