3 Future Oil-Spill Fighters: Sponges, Superbugs, and Herders
Amid efforts to cap the seafloor leak, cleanup workers have been using boat-based skimmers to pick up the oil, booms to gather the slick for burning, and chemical dispersants to break the crude into smaller droplets—all parts of the oil-fighting toolkit for decades. Soon, though, tech of the future could be cleaning up spills like this one.
Neuromarketers get inside buyers’ brains
Frito-Lay studied women’s brains to help develop an ad campaign, and Campbell Soup (CPB, Fortune 500) just unveiled a packaging redesign based on consumers’ “neurological and bodily responses” to different mockups. By hooking customers up to EEG or MRI machines, a company can learn about what’s really going on inside a buyer’s brain — possibly even before the buyer knows it.

Worms’ Paralysis Turned On and Off With Light
by Rachel KaufmanPublished in National Geographic News2009-11-20 If Dr. Horrible really did have a “freeze ray,” he might stop the world by zapping it with ultraviolet light, new research suggests. After feeding a light-sensitive chemical to transparent, microscopic worms called nematodes, scientists at Simon Fraser University in British Columbia were able to paralyze the tiny … Continue Reading
Marine Machines Made in Nature’s Image
If it looks like a fish and swims like a fish, it could be a robot–such as the University of Bath’s Gymnobot, inspired by an Amazonian knifefish.
Researchers worldwide are developing robots that look and act like aquatic creatures. That’s because biomimetic gadgets–bots that take inspiration from nature–are often more efficient than their clunkier counterparts.
