The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE; https://pace.gsfc.nasa.gov) mission, scheduled for launch in January 2024, will extend the continuous high-quality ocean color, atmospheric aerosol, and cloud data records begun by NASA in the late 1990s, building on the heritage of the Coastal Zone Color Scanner (CZCS), Sea-viewing Wide Field-of-view Sensor (SeaWiFS), Moderate Resolution Imaging Spectroradiometer (MODIS), and Visible Infrared Imaging Radiometer Suite (VIIRS) (Figure 1). PACE’s global hyperspectral imaging radiometer design concept will enable new discoveries in Earth’s living ocean (Figure 2), such as the diversity of organisms fueling marine food webs and how aquatic ecosystems respond to environmental change. Its instrument payload (Figure 3) will also observe Earth’s atmosphere to study clouds, airborne aerosol particles, and the interactions between the two. Looking at the ocean, clouds, and aerosols together will improve our knowledge of the roles each plays in our evolving planet. Other applications of PACE science data records—from identifying the frequency, extent, and duration of aquatic harmful algal blooms to improving our understanding of air quality—will result in direct economic, recreational, and societal benefits. Ultimately, by extending and expanding NASA’s long record of global Earth satellite observations, the PACE mission will monitor our home planet in new and advanced ways in the coming decade.

The PACE satellite observatory will follow a Sun synchronous, polar orbit at an altitude of 676.5 km with a local 13:00 Equatorial crossing time. Its payload consists of three instruments, a primary hyperspectral imaging radiometer being built at NASA Goddard Space Flight Center and two multispectral, multiangle polarimeters, the combination of which advances far beyond heritage capabilities. The Ocean Color Instrument (OCI) offers one-day global coverage with a ground sample distance of 1 km2 at nadir. As described in this OceanShot, this leap in technology will enable improved understanding of aquatic ecosystems and biogeochemistry, as well as provide new information on phytoplankton community composition and improved detection of algal blooms.\n\nOCI will be complemented by two small multi-angle polarimeters with spectral ranges that span the visible to near infrared spectral region. When sunlight interacts with clouds or aerosols, it comes away from that interaction changed. By measuring changes in how reflected light oscillates within a geometric plane (i.e., its viewing angle-specific polarization), we can infer useful properties of the clouds or aerosols. This information is crucial to deciphering the way sunlight is reflected and absorbed by our planet and how aerosols affect cloud formation. The polarimeters include the Spectro-polarimeter for Planetary Exploration (SPEXone) and the Hyper Angular Research Polarimeter (HARP2), both of which will significantly improve aerosol and cloud characterizations and provide opportunities for novel ocean color atmospheric correction. (Figure 3). These instruments offer complementary capabilities: SPEXone is hyperspectral, multiangular, and narrow swath to support advanced atmospheric aerosol characterizations, whereas HARP2 is multispectral, hyper-angular, and wide swath to advance cloud property retrievals. In total, the combined PACE instrument suite will revolutionize studies of global biogeochemistry, carbon cycles, and air–sea exchanges in the ocean–atmosphere system.

Since the concept of sustainability is linked to the problems of daily life, educational games are an important tool to teach this concept and to reveal perceptions about this concept. This study aims to determine science teachers' views on the concept of sustainable development through educational games. This study is a phenomenological study. The study group of this study consists of 37 science teachers. In the research, five semi-structured interview questions prepared by the researchers were used as data collection tool. When the results obtained from the research were examined, it was found that teachers associated the concept of sustainable development less with the words environment and next generation rather than other words. Teachers explained the main idea of the game around the themes of society, environment and economy. In addition, teachers stated that the game process affects them in terms of knowledge, attitudes and values, behavior about sustainable resources. Most of the teachers stated that they will play the game differently after they learn what the cards and resources in the game mean. Teachers mostly explained that they would try not to consume resources and would protect non-renewable resources. Finally, after the game, the teachers classified the countries in today's world into three categories as developed countries, developing countries and underdeveloped countries.

Background: Humanity's current use of resources is not in line with the goal of sustainable development. Climate change impact scenarios appear worryingly pessimistic. The agricultural and food production accounts for a particularly high share of the impact, and this also holds for consumption of food. Transforming food consumption plays a crucial role in tackling the challenges, and sensory consumer science can contribute to this. Scope and approach: This commentary examines what is required of the agricultural and food sector in order to sustainably transform, and outlines the current research streams in sensory consumer science from a sustainability perspective. Based on a comparison of the requirements and research, we suggest a categorization of the contributions that sensory consumer science can make to sustainable development. Key findings and conclusions: Six necessary transformations to which sensory consumer science can make a contribution are derived and outlined: 1) promotion of a dietary shift towards more sustainable foods and diets, 2) increase of food diversity, 3) food waste reduction, 4) enhancement of the circularity of the food system, 5) heightening and prioritising food-related well-being, and 6) coping with the effects of climate change. So far, sensory consumer science studies have focused on foods regarded as sustainable (e.g. organic, sustainably claimed, insects and meat alternatives) as well as issues that contribute to sustainability (e.g. shelf-life, fruit and vegetable consumption, unfamiliar food). The conclusion for further future research is that designing sensory consumer science research to explicitly target the six required transformations can increase the discipline's contribution to sustainable development.

The Congress and Exhibition Series ""Arsenic in the Environment"" offers an international, multi- and interdisciplinary discussion platform for research and innovation aimed towards a holistic solution to the challenges posed by the environmental toxin arsenic, with global societal impact. The Congress has focused on cutting edge and breakthrough research in physical, chemical, toxicological, medical, agricultural and other specific issues on arsenic across a broader environmental realm. The Biennial Congress and Exhibition ""Arsenic in the Environment"" was first organized in Mexico City (As2006) followed by As2008 in Valencia (Spain), As2010 in Tainan (Chinese Taiwan), As2012 in Cairns (Australia), As2014 in Buenos Aires (Argentina), As2016 in Stockholm (Sweden) and As2018 in Beijing (P.R. China). The 8th International Congress As2020 was held June 7-9, 2021 (first time digitally owing to the global COVID-19 pandemic, in Wageningen, The Netherlands) and with a title Arsenic in the Environment - Bridging Science to Practice for Sustainable Development. The Congress addressed the broader context of arsenic research aligned on the following themes: Theme 1: Arsenic in Natural Soil and Water Systems Theme 2: Arsenic in Agriculture and Food Production Theme 3: Health Impacts of Arsenic Theme 4: Technologies for Arsenic Removal from Water Theme 5: Sustainable Mitigation and Management for Sustainable Development Arsenic in drinking water and food is a major health issue, affecting millions of people in many parts of the world. In recent years serious cases of arsenic exposure through different environmental matrices have been reported from, for example, Argentina, Bangladesh, Chile, China, Taiwan, Turkey, India, Mexico, UK, USA, Pakistan, Vietnam as well as other regions in the world. Arsenic can cause a number of carcinogenic and non-carcinogenic adverse effects on human health and therefore human exposure to arsenic should be avoided. Notably, The Netherlands has been in the forefront of research on arsenic removal technology and developed a cutting edge innovation to remove arsenic to levels below the WHO drinking water guideline to as low as less than 1 μg/L. This has created an enabling environment to discuss on policy issues for defining the new drinking water guideline. The Congress has attracted professionals involved in different segments of interdisciplinary research on arsenic in an open forum, and strengthened relations between academia, research institutions, government and non-governmental agencies, industries, and civil society organizations to share an optimal ambience for exchange of knowledge.
