Smell Camera Snapshots Scents For the Future 117

An anonymous reader writes "Designer Amy Radcliffe has created an 'analog odor camera' that can be used to recreate a smell. From the article: 'When a smell source is placed under the device's glass cone, a pump extracts the smell via a plastic tube. After being drawn to Madeleine's main unit, the smell goes through a resin trap which absorbs the particles so molecular information can be recorded. That data is expressed in a graph-like formula, which essentially contains a fingerprint of the smell. In a special lab, that formula can then be inscribed on a bronze disk to artificially reproduce the smell. The smell can also be recreated in small vials.'"

Improving 3-D Printing By Copying Nature 128

from the build-it-better dept.
An anonymous reader writes "Biologist Janine Benyus is excited about the 3-D printer revolution and she thinks it can be improved by modeling natural processes. 'Benyus, who wrote Biomimicry: Innovation Inspired by Nature and co-founded the institute Biomimicry 3.8, would like to see a transition in manufacturing—from big, smoke-belching factories to small, clean desktop printers. The key to making it truly sustainable, she said, lies in mimicking how a natural ecosystem functions. "Nature uses life-friendly chemistry, which is nontoxic and water-based, and which does not require high heat," said Benyus. In contrast, most of the products people use today have been forged in industrial-size furnaces, with a plethora of toxic solvents. A potato chip bag may seem like a simple item, but it is actually made up of several thin layers of different materials, one to make it strong, one to make it airtight, and so on.'"

Researchers Complete New Gondwana Map 116

Posted by samzenpus
from the old-directions dept.
An anonymous reader writes "A new computer simulated map has revealed the past position of the Australian, Antarctic and Indian tectonic plates, demonstrating how they formed the supercontinent Gondwana 165 million years ago. 'It was a simple technique, matching the geological boundaries on each plate. The geological units formed before the continents broke apart, so we used their position to put this ancient jigsaw puzzle back together again,' said Lloyd White of Royal Holloway University in a press release. 'We found that many existing studies had positioned the plates in the wrong place because the geological units did not align on each plate.'"
