Migration of D-type asteroids from the outer Solar System inferred from carbonate in meteorites

Recent dynamical models of Solar System evolution and isotope studies of rock-forming elements in meteorites have suggested that volatile-rich asteroids formed in the outer Solar System beyond Jupiter’s orbit, despite being currently located in the main asteroid belt. The ambient temperature under which asteroids formed is a crucial diagnostic to pinpoint the original location of asteroids and is

Finding intersections between electronic excited state potential energy surfaces with simultaneous ultrafast X-ray scattering and spectroscopy

Light-driven molecular reactions are dictated by the excited state potential energy landscape, depending critically on the location of conical intersections and intersystem crossing points between potential surfaces where non-adiabatic effects govern transition probabilities between distinct electronic states. While ultrafast studies have provided significant insight into electronic excited state

Body temperature responses of Great Tits Parus major to handling in the cold

Animals typically respond to stressful stimuli such as handling by increasing core body temperature. However, small birds in cold environments have been found to decrease body temperature (Tb) when handled over longer periods, although there are no data extending beyond the actual handling event in such birds. We therefore measured both the initial Tb decrease during ringing and standardized Tb sa

Evolution of replacement therapy for von Willebrand disease : From plasma fraction to recombinant von Willebrand factor

The diagnosis and treatment of von Willebrand disease (VWD) are challenging, in part because patients exhibit a wide range of bleeding patterns and manifestations (e.g. epistaxis, gingival bleeding, heavy menstrual bleeding, gastrointestinal bleeds, postoperative bleeding, hemarthroses) and in part because many tests are required to make an accurate diagnosis. Factor replacement therapies for VWD

Spatio-temporal interdependence of bacteria and phytoplankton during a baltic sea spring bloom

In temperate systems, phytoplankton spring blooms deplete inorganic nutrients and are major sources of organic matter for the microbial loop. In response to phytoplankton exudates and environmental factors, heterotrophic microbial communities are highly dynamic and change their abundance and composition both on spatial and temporal scales. Yet, most of our understanding about these processes comes

STEPS towards a sustainable plastics system in a circular economy

Plastics are an integrated and important part of the global economy. Plastics have now come under close scrutiny for the ecological impact that their production, widespread use and disposal are having on our planet. Urgent solutions for a more sustainable plastics system are thus being requested, such as increasing their reuse and recycling in a circular economy by improvements in design and produ

Sustainable transition pathways for plastics

Plastic – the lightweight, flexible material created by humans – has been an amazing invention that changed the world and made us totally dependent on it. The past century saw the development of a number of synthetic plastic materials with different chemistries and properties suited for myriad applications unparalleled by any other natural material. However, the plastics are currently in focus not

Cross-Linguistic Influence in Early Word Learning

It has often been the presumption that reverse cross-linguistic influence requires an advanced fluency in the second language. This assumption has led to much of the research focusing on the impact of the speaker’s existing languages towards their second or third language. Our mental lexicons are, however, in a constant state of change through learning, forgetting, and consolidation, and we should

The European Butterfly Indicator for Grassland species: 1990-2015

This report presents the sixth version of the European Grassland Butterfly Indicator, one of the EU biodiversity indicators of the European Environment Agency.The indicator is based on more than 9200 transects in national Butterfly Monitoring Schemes covering 22 countries across Europe, most of them active in the European Union. In 2015, counts were made in more than 4500 transects.Butterflies rep
