Material support of all manned space flights so far has been provided from a prestored stock of substances or replenished from the Earth's biosphere. Exploration of space will, however, become real only when man is able to break away from Earth completely, when he will be accompanied by a system providing everything necessary to sustain full-valued life for an unlimited time. The only known system to date meeting this requirement is the Earth's biosphere. To break away from his cradle, as K.E. Tsiolkovsky called Earth, it is necessary to devise a life support system functionally similar to the natural biosphere. This need not be similar in structure to the vast diversity of trophic relationships available on Earth, but requires the solution of a multitude of various problems of an ecological, physiological, engineering and social-psychological nature. Human life-support systems based on biological regeneration of environments in small volumes have been studied at the Institute of Biophysics (Siberian Branch of the Russian Academy of Sciences) over many years. This work has resulted in the design of Bios-3, a biologically-based self-sustained human life support system.

Objectives: To incorporate a longitudinal palliative care curriculum into obstetrics and gynecology (Ob-Gyn) residency that could become standardized to ensure competencies in providing end of life (EOL) care.

Methods: This was a prospective cohort study conducted among 23 Ob-Gyn residents at a tertiary training hospital from 2021 to 2022. A curriculum intervention was provided via lecture and simulation.

Teaching death, spirituality, and palliative care to university students: Novel pedagogical approach.

Palliat Support Care

January 2025

Department of Theology and Religious Education, College of Liberal Arts, Manila, Philippines.

Teaching death, spirituality, and palliative care equips students with critical skills and perspectives for holistic patient care. This interdisciplinary approach fosters empathy, resilience, and personal growth while enhancing competence in end-of-life care. Using experiential methods like simulations and real patient interactions, educators bridge theory and practice.

Objectives: Explore humanitarian healthcare professionals' (HCPs) perceptions about implementing children's palliative care and to identify their educational needs and challenges, including learning topics, training methods, and barriers to education.

Methods: Humanitarian HCPs were interviewed about perspectives on children's palliative care and preferences and needs for training. Interviews were transcribed, coded, and arranged into overarching themes.

Objectives: People with life-limiting diseases, who are no longer receiving active or curable treatment, often state their preferred place of care and death as the home. This requires coordinating a multidisciplinary approach, using available health and social care services to synchronize care. Family caregivers are key to enabling home-based end-of-life support; however, the 2 elements that facilitate success - coordination and family caregiver - are not necessarily associated as being intertwined or one and the same.

Niche shift and localized competitive dynamics influence the persistence and distribution of polyploids in the genus Achillea (Asteraceae).

Ann Bot

January 2025

Key Laboratory of Biodiversity Science and Ecological Engineering of the Ministry of Education, College of Life Sciences, Beijing Normal University, Beijing, China.

Background And Aims: Competition with sympatric diploid progenitor(s) hinders the persistence of polyploids. The hypothesis that polyploids escape from competition through niche shifts has been widely tested; however, niche escape is unlikely to completely avoid competition. Given species growing in less favorable environments likely have weaker competitive abilities, we hypothesize that polyploid populations tend to persist in areas where their progenitors with relatively low habitat suitability.
