This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"In terrestrial and freshwater ecosystems, fungi are essential for nutrient cycling, releasing carbon dioxide into the atmosphere and inorganic nitrogen and phosphorus into the soil. In contrast, in marine environments, fungi are often considered to be associated with debris and less essential to the element cycle than other microbes such as prokaryotes and phytoplankton. A recent study sought to better understand the role of open-sea, or pelagic, fungi in carbon cycling in the ocean. Using multi-omics techniques and existing genomic datasets, researchers performed a global analysis of carbohydrate-active enzymes (CAZymes) – key enzymes in carbon cycling – in ocean fungi. They found that pelagic fungi are active in carbohydrate degradation, as indicated by a high ratio of CAZyme transcripts..."

In this learning activity, students use a web-based carbon calculator to determine their carbon footprint on the basis of their personal and household habits and choices. Students identify which personal activities and household choices produce the most CO2 emissions, compare their carbon footprint to the U.S. and global averages, and identify lifestyle changes they can make to reduce their footprint.

This video features a short animated sequence that illustrates the difference between young and old carbon released into the atmosphere from the consumption of food (young carbon) and the burning of fossil fuels (old carbon).

"For decades they’ve taken a backseat to their mineral counterparts. But today, organic materials are booming—not least of all for their applications in lithium-ion batteries. A new review article published in the journal ChemPlusChem discusses how one class of organics in particular is poised to yield high performance from a tiny but versatile package: carbonyl-based π-conjugated compounds. Like other organic materials, carbonyl-based π-conjugated materials present a unique and much-needed solution to the global energy crisis. Flexible, light, and naturally abundant, these compounds offer the prospect of nimble energy-storage systems with energy and power densities comparable to inorganic systems. What sets carbonyl-based π-conjugated materials apart from other organics is highly tunable electrochemical performance stemming from a versatile starting structure. The redox mechanism of carbonyls proceeds by a reversible one-electron reduction to form a radical mono-anion and the reverse reaction..."

The mammalian cardiovascular and respiratory systems have evolved primarily to provide the tissues of the body with oxygen and to remove carbon dioxide. The cardiorespiratory system also has metabolic and heat exchange roles.

This lesson consists of a basic introduction to the cardiovascular and respiratory system(s) along with basic (common) diseases within each system. Diseases include atherosclerosis, heart attack, stroke, COPD (emphysema, chronic bronchitis). Screenings to detect various forms of cardiovascular disease are also included at an introductory level.

Written nursing care plans ensure that the nurse responsible for patient care at any time during the animal's stay in the practice is confident to manage and treat the patient, to talk to the owners and give accurate updates on their animal's care, and to feel that the best possible care has been given to the animal at all times. Care plans require skill to write and this is something that improves with practise.

"Being a doctor takes its toll. Demanding workloads and performance standards can be unremitting on all doctors. In obstetrics and gynecology, we often face unique emergencies and must make quick decisions. Unlike most other specialists, OB/GYNs must respond quickly to patient demands, operate confidently and skillfully, conscious of risk, and be “on" at a moment’s notice. Understandably, OB/GYNs report some of the highest burnout rates among physicians. It’s a long-standing problem that’s finally getting attention from the medical community. In 2017, the World Medical Association made a critical addition to the Physician’s Pledge: “I WILL ATTEND to my own health, well-being, and abilities in order to provide care of the highest standard.” We must acknowledge the unique expectations of birth and further investigate the rates and impact of burnout in RANZCOG trainees and specialists in order to safely deliver the next generation..."

Each mammary complex consists of 5-20 mammary units and their corresponding ducts. The ducts open separately on the tip of the teat. Shallow grooves indicate the border between complexes. An intermammary sulcus divides the right from the left row.

No final do ano de 2019 apareceu o primeiro caso de COVID-19 na China e, pouco tempo depois, em 2020, foi decretada a situação de pandemia. Desde então, estamos nos deparando a todo momento com dados dispostos em tabelas e gráficos sobre o nível de contaminação, morte e recuperação por COVID-19. Essas informações chegam também às crianças através dos meios de comunicação, tornando importante que sejam debatidas com elas as causas e consequências da pandemia, incluindo a importância do isolamento social e campanhas de vacinação. A cartilha digital intitulada Aprendendo Estatística em Tempos de COVID-19, destaca a importância da Estatística no combate a uma situação pandêmica nas aulas de Matemática nos anos iniciais do ensino fundamental, utilizando tabelas e gráficos, informações reais sobre a taxa de contaminação da COVID-19 e dados sobre a campanha de vacinação no Brasil.
