Seen here is dirt. Well, more specifically, it's the first nanoscale image of soil. Cornell University researcher used X-ray spectromicroscopy to study the structure and composition of soil carbon at a scale of 50 nanometers. (One nanometer is about 100,000 times smaller than the diameter of a human hair.) They determined that even the tiniest samples of soil taken just micrometers apart can have vastly different compositions. From the Cornell Chronicle:
According to a study published in the April issue of Nature Geoscience, knowing the structure and detailed composition of soil carbon could provide a better understanding of the chemical processes that cycle organic matter in soil. For example, the research may help scientists understand what happens when materials in the soil get wet, warm or cool and how soils sequester carbon, which has implications for climate change.
"There is this incredible nanoscale heterogeneity of organic matter in terms of soil," said Johannes Lehmann, a Cornell associate professor of crop and soil sciences and lead author of the study. "None of these compounds that you can see on a nanoscale level looks anything close to the sum of the entire organic matter."
The office I work in is full of things old people buy to make themselves feel young again. I can honestly say that our awesome new toy, The Swagtron T3 Hoverboard, makes me feel very, very old. I’ll explain why later. Swagtron T3 Pros There’s no way to overcharge the battery and that means no […]
One thing that’s consistent among amateur pool players is that they unknowingly stand up during their shots. Just as in golf, pool players need to keep their heads down and stay still after they shoot in order to hit straight. The DIGICUE helps keep shots consistent by letting you know every time you’ve had extra […]
A leaked memo from Apple CEO Tim Cook to his staff explaining why he met with Donald Trump — a guy who called Apple traitors for refusing to defeat their own security — explains the rationale: “tax reform.”
