Matija Strlic and colleagues write in the ACS's Analytical Chemistry about "material degradomics," a techniques by which the odors emanating from old books are noninvasively analyzed to figure out which books are rotting and need preservation:
Matija Strlic and colleagues note in the new study that the familiar musty smell of an old book, as readers leaf through the pages, is the result of hundreds of so-called volatile organic compounds (VOCs) released into the air from the paper. Those substances hold clues to the paper's condition, they say. Conventional methods for analyzing library and archival materials involve removing samples of the document and then testing them with traditional laboratory equipment. But this approach destroys part of the document.
The new technique, called "material degradomics," analyzes the gases emitted by old books and documents without altering the documents themselves.
A favorite kitchen chemistry (and physics) experiment of kids (and adults), Ooblek is the weird result of mixing cornstarch with water. Now, MIT engineers have developed a mathematical model that can predict and simulate how the non-Newtonian fluid switches between liquid and solid depending on the pressure applied to it. From MIT News: Aside from […]
Remember when the default state of your online presence was anonymity? That’s not so clear-cut anymore, and the worst part is you may not even know who is using your data or what they’re using it for. Small wonder that so many people are choosing to surf through virtual private networks. VPNs filter web access […]

All you have to do is sign up, and you’re entered to win this ultimate Netflix plan. When does it expire? Only when you do. And hey, just in case you need something […]
There’s overwhelming support for clean energy, and the planet is giving us more reasons to invest in renewable power sources with every passing year. Even in the most inhospitable areas, wind and solar can provide a good chunk of our power, if not all of it. So why aren’t we all taking advantage of it? […]
