Butterfly vs shark: nature's clues to anti-dust materials

By - November 8, 2012 8 Pictures
Butterfly wings cannot be very far behind geckos' toes so far as sources of inspiration for biomimicry research goes. Various properties of the wings of lepidopterans have triggered research into banknote forgery prevention, light reflection and solar cells. New research from Ohio State University suggests the delicate membranes may hold clues to dirt-resistance surfaces. Read More

Liquid laundry additive turns clothes into air purifiers

By - October 1, 2012 3 Pictures
A laundry additive created by researchers from the University of Sheffield and the London College of Fashion turns clothing into a photocatalytic material that can help remove nitrogen oxides (NOx) from the air. One of the most prominent air pollutants, nitrogen oxides are emitted from the exhausts of ICE-powered vehicles and aggravate asthma and other respiratory diseases. The researchers claim one person getting around town in clothing treated with the additive for a day would be able to remove roughly the same amount of nitrogen oxides produced by the average family car each day.

Newly developed nanoparticles shine from deep within biological tissue

By - October 1, 2012
Deep-tissue optical imaging may soon be getting easier – or at least, the images may soon be getting sharper. That’s because an international team of scientists have developed photoluminescent nanoparticles that are able to shine through over three centimeters (1.2 inches) of biological tissue. If attached to anomalies deep beneath the skin, the nanoparticles could allow those anomalies to be seen more clearly from the outside. Read More

Superhydrophobic coating allows water to boil without bubbles

By - September 14, 2012
You know that thing that water does when it boils? The thing with the bubbles? Turns out, it doesn't really need to do that at all, with scientists finding a way to make boiling water a completely bubble-free zone. Researchers from Northwestern University, King Abdullah University of Science and Technology in Saudi Arabia and Melbourne University in Australia teamed up to prevent water from bubbling when it boils by using tiny spheres coated with a hydrophobic material.

MIT researchers devise technique to clean up oil spills using magnets

By - September 12, 2012
Possibly the only good thing to come out of the Deepwater Horizon disaster is the subsequent increase in research into finding more effective ways to clean up oil spills, including such initiatives as the X PRIZE Foundation's Wendy Schmidt Oil Cleanup X CHALLENGE. Joining the list is a new method devised by researchers at MIT who propose separating oil and water using magnets. The new technique would allow the oil to be recovered to help offset the costs of the cleanup operation. Read More

“Nano-velcro” traps and detects heavy metals in contaminated waterways

By - September 11, 2012
While progress has been made in reducing the amount of heavy metal pollution, the very nature of heavy metal contamination means it continues to be a problem in waterways around the world. Conventional heavy metal contamination detection methods require sending samples off to a lab for analysis on expensive equipment. Now a Swiss-American team has developed a cheap way to immediately ascertain the levels of heavy metals in lakes and rivers and the fish pulled out of them. Read More

"Whispering gallery" biosensor detects the smallest viruses

By - August 28, 2012 2 Pictures
Researchers led by Professor Stephen Arnold at Polytechnic Institute of New York University have developed a new ultra-sensitive biosensor. Currently undergoing commercial development, the sensor is designed to inexpensively identify viruses in a doctor’s office within a matter of minutes instead of the weeks needed by conventional techniques ... and it can detect even the smallest RNA virus particle, MS2, which weighs only six attograms (10-18 grams).

Researchers produce ink and dye-free 100,000 DPI images

By - August 14, 2012 3 Pictures
Researchers at Singapore's Institute of Materials Research and Engineering (IMRE), an institute of the Agency for Science, Technology and Research (A*STAR), have developed an innovative method of creating sharp, full-spectrum color images at 100,000 dots per inch (DPI). The method achieves this without need of ink or dye and bests the current crop of industrial inkjet and laserjet printers which are only able to offer up to 10,000 DPI. The new research also promises to outperform research-grade methods, which are able to dispense dyes for only single color images. Read More
