Abstract	Background: The COVID-19 pandemic has dramatically affected mental health, creating an urgent need for convenient and safe interventions to improve well-being. Online mindfulness interventions show promise for improving depression, anxiety, and general well-being. Objective: To assess: 1) the impact of online mindfulness on psychological distress, 2) altruistic efforts, and 3) the quantity, quality, and availability of online mindfulness resources during the COVID-19 pandemic. Methods: 233 participants (203 U.S.; 20 international; 10 unknown) participated in this prospective, single-arm, non-randomized clinical trial of a single online mindfulness meditation session with pre- and post-surveys. Main outcome measures: (a) Mindfulness session helpfulness, online platform effectiveness, and immediate pre- to post-session changes in momentary stress, anxiety, and COVID-19 concern; (b) qualitative themes representing how people are helping others during the pandemic; (c) absolute changes in quantity of mindfulness-oriented web content and free online mindfulness resource availability from May to August 2020. Results: Most participants felt the online mindfulness session was helpful and the electronic platform effective for practicing mindfulness (89%, 95% CI: [82 to 93%]), with decreased momentary anxiety (76%; 95% CI: [69 to 83%]), stress (80%; [72 to 86%]), and COVID-19 concern (55%; [46 to 63%]), (p < 0.001 for each measure). Participants reported helping others in a variety of ways during the pandemic, including following public health guidelines, conducting acts of service and connection, and helping oneself in hopes of helping others. "Mindfulness + COVID" search results increased by 52% from May to August 2020. Most (73%) Academic Consortium for Integrative Medicine and Health member websites offer free online mindfulness resources. Conclusions: Virtual mindfulness is an increasingly accessible intervention available world-wide that may reduce psychological distress during this isolating public health crisis. Kindness and altruism are being demonstrated during the pandemic. The consolidated online mindfulness resources provided may help guide clinicians and patients.

Abstract	A large part of the daily intake of children in the U.S. consists of snacks, with the average child consuming three snacks per day. Despite this, little research has been conducted to determine the metabolic and behavioral effects of snacking. Using a developing female rat model, our studies aimed to determine the effects of snacking during development before the protective effects of estrogen on weight gain would be relevant. Additionally, to determine if snack composition is important, we created one healthy and one unhealthy snacking group provided with chow and three snacks each in addition to a chow-only group. We found that both snacking groups experienced increased weight gain, elevated abdominal fat pad mass, prolonged leptin resistance into adulthood, and insulin insensitivity that was not observed in their non-snacking counterparts. These physiological differences were measured despite both snacking groups having a similar caloric intake as the chow-only group throughout the study. In addition to physiological changes, both snacking groups showed a preference for snacks over chow and ate more often during the inactive light phase than typical for rats, with the unhealthy snacking group presenting this behavioral change earlier than the healthy snacking group. Our results suggest that constant access to palatable snacks, which is often the case for children in western countries, alters feeding behaviors in relation to food choice and time of day when eating occurs. Snacking during development seemed to promote signs of metabolic syndrome in adulthood even when excess caloric intake was not observed. Our work further suggests that development is a vulnerable time for palatable snack presentation when prepubertal females lack the protective effects of estrogen and exhibit reduced leptin feedback on food intake. Thus snacking from weaning onward could be a contributor to the current childhood obesity crisis.

Abstract	The growth of low-dimensional nanostructures of Au on Ge(110) and their temperature-induced motion were observed with Low Energy Electron Microscopy (LEEM). Ge(110) was dosed with 0.5-4 ML of Au and heated to 850°C. Above 500°C, liquid AuGe eutectic alloy islands grew on the surface. Islands were 0.3-3.0µm in width, 1-10µm in length, and elongated in the [11¯0] direction. Above 600°C, islands began moving with speeds of 0.1-1.0µm/s, absorbing smaller stationary islands upon collision and increasing in size to more than 100µm in width. A temperature gradient of ∼0.017°C/µm across the sample results in a gradient in the Ge concentration across the islands, inducing their movement in the direction of increasing temperature. Optical microscopy confirmed that the large islands moved from the cooler edges of the sample towards its hotter center. The mechanism for motion of the droplets is discussed, and the island velocities fit well to a model for diffusion-driven motion of the liquid droplet. When the temperature was subsequently lowered, islands became supersaturated with Ge, which crystallized on the island edges.

Abstract	Submarine groundwater discharge (SGD) studies have focused on nutrient fluxes to coastal zones in many regions of the world. However the role of SGD in carbon cycling and fluxes is less well studied. We traced SGD-derived dissolved inorganic carbon (DIC) through a subterranean estuary using Δ¹⁴C and δ¹³C to evaluate how water residence times and carbon sources affected cycling and potential DIC fluxes to coastal waters. Samples were collected from the Indian River Lagoon subterranean and surface estuaries for analysis of DIC concentrations and natural ∆¹⁴C-DIC and δ¹³C-DIC abundances. Pore-water samples were collected from multiple depths at three piezometer stations along a 250-m long transect perpendicular to shore and extending across the seepage face (about 20–22m from shore). This approach captured the gradient from rapid, fresh groundwater discharge at the shoreline, across the groundwater–seawater subterranean mixing zone, and into purely marine offshore sediments beyond the seepage face. Freshwater and marine end-member DIC samples were also collected from a beach well and overlying lagoon surface waters beyond the seepage face, respectively. Older ∆¹⁴C-DIC and more enriched δ¹³C-DIC values were observed at the shoreline than at the beach well (∆¹⁴C: −431‰±31, δ¹³C: −9.1‰±1.0 versus ∆¹⁴C: −108‰, δ¹³C: −16.9‰, respectively), indicating the influence of carbonate dissolution along the groundwater flow path. Pore-water DIC isotopic values indicate the groundwater plume extends from the base of the shoreline profile (115cmbsf) to the distal end of the freshwater seepage face 20–22m offshore. The application of dual isotope, two- and three-end-member mixing models shows DIC sources change with increasing distance from shore, transitioning from a groundwater dominated system nearshore, to a mixing zone, and then into the seawater recirculation system beyond the mixing zone seepage face. Contributions from organic carbon remineralization increased with distance from shore and had varying effects on carbonate dissolution, depending on flow paths, residence times, and redox conditions. Our study demonstrates the connectivity of unconfined coastal aquifers to surface water estuaries and illustrates how hydrologic and biogeochemical complexities within the subterranean estuary can significantly contribute to the variations in sources of DIC. Furthermore, these findings highlight the importance of qualitative tracing of DIC sources together with an in-depth consideration of in situ biogeochemistry and quantitative SGD estimates. Understanding how spatial changes in hydrology and biogeochemical conditions contribute to the composition and flux of SGD-derived older DIC to coastal waters elucidates the role subterranean estuaries may ultimately play in the global carbon budget.

Abstract	The concentration of dissolved organic carbon (DOC) in groundwater emanating as spring discharge at several locations in Florida, USA and the net increase in DOC in the downstream receiving waters were measured as part of a larger investigation of carbon dynamics in flowing waters. Springs with high discharge (>2.8 m 3 s −1 ) were found to be the most organic-poor natural waters yet reported (13 ± 1.6 μmol C L −1 ), while springs with lesser discharge exhibited somewhat higher DOC concentrations (values ranging from 30 to 77 μmol C L −1 ). DOC concentrations increased rapidly downstream from the point of spring discharge, with the calculated net areal input rate of DOC ranging from 0.04 to 1.64 mol C m −2 d −1 across springs. Rates of DOC increase were generally greater in those springs with high discharge rates. These input rates compare favorably with values reported for gross primary production in these macrophyte-dominated spring systems, assuming that 17% of macrophyte primary production is lost, on average, as DOC. The measures reported here are possible only because of the remarkably low DOC levels in the up-surging groundwaters and the short residency times of the water in the spring-runs themselves.
