Underground hydrogen storage (UHS) in depleted gas reservoirs is an effective strategy for balancing renewable energy supply and demand, with cushion gases being used to maintain storage pressure. Here CO 2 is investigated as a cushion gas via measurements of the dispersion between hydrogen and CO 2 in a (Bentheimer sandstone) rock core, performed at reservoir-relevant conditions using a novel core flooding apparatus. Such dat...
Self-powered intracardiac implant devices show great promise for future clinical applications due to their extended operational lifespan and the potential to reduce the need for high-risk repeat surgeries. This study investigates the feasibility of harvesting energy from cardiac motion through in vivo testing of intracardiac devices. Comprehensive three-dimensional translational and rotational cardiac motions are captured in a...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...

Are Ecotonal Systems More Sensitive to Climate Change? Past Ecotonal Dynamics and Rates of Vegetation Change in MichiganNARA Subscribed
Aim Ecotones are expected to be sensitive to climate change, but supporting evidence is scarce. Here we test the ecotonal sensitivity hypothesis by reconstructing past movements of a major temperature‐governed forest ecotone (the Tension Zone, separating temperate deciduous forests and northern mixed hardwood‐conifer forests) and comparing the variability of ecotone‐proximal and distal vegetation. Location Michigan, United Sta...
The applicability of regional red list assessments for soil invertebrates: first assessment of five native earthworm species in CanadaNARA Subscribed
Earthworms (Annelida: Clitellata: Crassiclitellata) are prominent members of the soil community, important to many ecosystem functions. Despite this, and like many other soil invertebrates, they are rarely considered in conservation assessments, including the International Union for Conservation of Nature (IUCN) Red List assessments used to assess species’ extinction risk. To investigate the applicability of the IUCN Regional...
