    Identification and properties of intense star-forming galaxies at redshifts z > 10

    Surveys with the James Webb Space Telescope (JWST) have discovered candidate galaxies in the first 400 Myr of cosmic time. Preliminary indications have suggested these candidate galaxies may be more massive an...

    Nitrogen-induced boron deficiency in lucerne

    In a glasshouse experiment with a boron deficient soil the application of nitrogen was found to decrease the boron concentration and boron uptake by lucerne (Medicago sativa). Without added boron, nitrogen applic...
