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."
Where are our petabyte drives? Brian Hayes takes us through the reasons storage is “stuck” in the low terabytes. The tl;dr is that we got such exceptional capacity growth in the late 90s and early 00s we don’t need much more right now, so the focus since then has been on SSDs, networking, interfaces, etc, […]
Amélie Lamont, a former staffer at website-hosting startup Squarespace, writes that she often found herself disregarded and disrespected by her colleagues. One comment in particular, though, set her reeling — and came to exemplify her experiences there.

3D printing has been one of those “next big thing” innovations among early adopters and the tech circle in-crowd for a few years now. However, the prospect of creating your own three-dimensional objects is still in its relative infancy with the general public. While the idea itself is fascinating to most, high prices and the […]
White hat hackers get paid to find holes in their own employers’ online systems, and plug those holes before they become serious security risks. It’s a job that pays handsomely…mostly because few job candidates, even experienced IT professionals, have the skills to scamper over firewalls and infiltrate the deepest recesses of a battle-tested network. But […]
Why buy one of those expensive and confusing universal remotes, clogged with enough buttons to launch a space shuttle, when you could accomplish the same electronic control right on your favorite mobile device? The Blumoo Universal Remote, now just $52.99 in the Boing Boing Store, harnesses the audio power of all your household equipment right […]
