Interdisciplinary work yields new, easier, less destructive way to examine diets of ancient peoples by using dental calculus While we may brush and floss tirelessly and our dentists may regularly scrape and pick at our teeth to minimize the formation of plaque known as tartar or dental calculus, anthropologists may be rejoicing at the fact that past civilizations were not so careful with their dental hygiene. University of Nevada, Reno researchers G. Richard Scott and Simon R. Poulson...

Modern Hybrid Corn Makes Better Use Of Nitrogen
2012-04-30 10:46:38

Today's hybrid corn varieties more efficiently use nitrogen to create more grain, according to 72 years of public-sector research data reviewed by Purdue University researchers. Tony Vyn, a professor of agronomy, and doctoral student Ignacio Ciampitti looked at nitrogen use studies for corn from two periods — 1940-1990 and 1991-2011. They wanted to see whether increased yields were due to better nitrogen efficiency or whether new plants were simply given additional nitrogen to...

Image 1 - Is Fertilizer To Blame For Global Warming?
2012-04-04 07:02:15

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...
