Abstract: Bose–Einstein condensates (BECs) are macroscopic coherent matter waves that have revolutionized quantum science and atomic physics. They are important to quantum simulation 1 and sensing 2,3 , for ex le, underlying atom interferometers in space 4 and ambitious tests of Einstein’s equivalence principle 5,6 . A long-standing constraint for quantum gas devices has been the need to execute cooling stages time-sequentially, restricting these devices to pulsed operation. Here we demonstrate continuous Bose–Einstein condensation by creating a continuous-wave (CW) condensate of strontium atoms that lasts indefinitely. The coherent matter wave is sustained by lification through Bose-stimulated gain of atoms from a thermal bath. By steadily replenishing this bath while achieving 1,000 times higher phase-space densities than previous works 7,8 , we maintain the conditions for condensation. Our experiment is the matter wave analogue of a CW optical laser with fully reflective cavity mirrors. This proof-of-principle demonstration provides a new, hitherto missing piece of atom optics, enabling the construction of continuous coherent-matter-wave devices.

Abstract: Research on choirs and other forms of group singing has been conducted for several decades and there has been a recent focus on the potential health and well-being benefits, particularly in amateur singers. Experimental, quantitative, and qualitative studies show evidence of a range of biopsychosocial and well-being benefits to singers however, there are many challenges to rigor and replicability. To support the advances of research into group singing, the authors met and discussed theoretical and methodological issues to be addressed in future studies. The authors are from five countries and represent the following disciplinary perspectives: music psychology, music therapy, community music, clinical psychology, educational and developmental psychology, evolutionary psychology, health psychology, social psychology, and public health. This article summarizes our collective thoughts in relation to the priority questions for future group singing research, theoretical frameworks, potential solutions for design and ethical challenges, quantitative measures, qualitative methods, and whether there is scope for a benchmarking set of measures across singing projects. With eight key recommendations, the article sets an agenda for best practice research on group singing.

Abstract: There is an increased interest in whether online arts interventions support mental health and social connections. This study explored eight weeks of online group dance as support for young people (aged 16-24) living with anxiety. The applicability of the ‘social cure’ theoretical framework to the novel context of an online dance class was sought. The study utilised an embedded QUAL+quan design, incorporating participatory focus group discussions (n=3 groups n=11 participants) and one-on-one interviews (n=2 participants), creative reflections (n=16 participants) and ethnographic fieldnotes, and a repeated measures design with surveys at three timepoints (week 1, n=27 week 4, n=18 week 8, n=14). Thematic analysis identified two overarching themes demonstrating how the dance classes i) provided the opportunity to co-construct a meaningful shared identity and ii) supported holistic wellbeing. This was supported by the quantitative findings suggesting lower anxiety, depression, and loneliness, and higher group bonding, self-esteem, and self-efficacy over time. This study expands the social cure to its application to an online dance class for the first time.
