Chemists from the University of California, Berkeley have discovered evidence of a link between increased fertilizer use and a rise in atmospheric nitrous oxide, a major greenhouse gas. Climate scientists have long assumed the cause of rising nitrous oxide levels in the atmosphere was due in part to nitrogen-based fertilizers. Such fertilizers are used to stimulate microbes in the ground to convert nitrogen to nitrous oxide at a faster rate. Published in the April issue of the journal...

Biologists at Bielefeld University have developed a new method for quantifying the effect of non-native species on ecosystem functioning They can estimate whether native plants in the neighbourhood of invasive species incorporate the nitrogen fixed by the latter. The biologists examined the Sydney Golden Wattle (Acacia longifolia), an Australian shrub that has established itself in Mediterranean climates worldwide. They found that the invasive species threatens native ecosystems not only...

By studying samples from carbon-rich meteorites, scientists with NASA's Goddard Space Flight Center say they have discovered that the building blocks of life can be created and maintained in extreme heat, not just in cooler conditions as had previously been believed. In a Friday press release, the U.S. space agency reports that experts from the Greenbelt, Maryland facility's Astrobiology Analytical Laboratory studied 14 samples and discovered "minerals that indicated they had experienced...

Highlights new research, and offers solutions for a nitrogen-soaked world The nitrogen cycle has been profoundly altered by human activities, and that in turn is affecting human health, air and water quality, and biodiversity in the U.S., according to a multi-disciplinary team of scientists writing in the 15th publication of the Ecological Society of America´s Issues in Ecology. In “Excess Nitrogen in the U.S. Environment: Trends, Risks, and Solutions,” lead author Eric...
