It’s amazing how quickly additive manufacturing technology has been progressing. Laser sintering of metals within the manufacturing industry was a process used by only a few companies, mostly in a research capacity, just a few years ago. Now numerous companies are using laser sintering additive manufacturing machines to print extremely important metal components for a variety of products, from airliners to race cars.

Laser Makes Regular Lightbulbs Super-Efficient

Laser Makes Regular Lightbulbs Super-Efficient

Everything is Better with Lasers 

What if you could take a regular incandescent lightbulb, zap it with a powerful laser for a small fraction of a second, and make it about twice as efficient as a regular lightbulb? That seems to be what researchers at the University of Rochester did. What does the laser do? It creates an “array of nano- and micro-scale structures on the surface of [the] regular tungsten filament-the tiny wire inside a light bulb-and these structures make the tungsten become far more effective at radiating light.”

Electronic Gadgets Could One Day Be Powered By Blood Flow

Electronic Gadgets Could One Day Be Powered By Blood Flow

This image show an experimental test of piezoelectric nanowires that harness a hamster’s wheel-turning energy into usable power. 

Power generated from flowing blood, simple body movements or a gentle breeze could one day be converted to electricity to charge iPods, cell phones and other personal electronic devices.

Need Another Reason To Quit Smoking – Third Hand Smoke

Need Another Reason To Quit Smoking - Third Hand Smoke 

 

Need another reason to add “Quit Smoking” to your New Year’s resolutions list? How about the fact that even if you choose to smoke outside of your home or only smoke in your home when your children are not there – thinking that you’re keeping them away from second-hand smoke – you’re still exposing them to toxins? In the January issue of Pediatrics, researchers at MassGeneral Hospital for Children (MGHfC) and colleagues across the country describe how tobacco smoke contamination lingers even after a cigarette is extinguished – a phenomenon they define as “third-hand” smoke. Their study is the first to examine adult attitudes about the health risks to children of third-hand smoke and how those beliefs may relate to rules about smoking in their homes.

New Plasma Technology Waterproofs Without Affecting Treated Surface

New Plasma Technology Waterproofs Without Affecting Treated Surface

Imagine a world without yellow raincoats, umbrellas in all shapes and sizes and who knows, you will never experience what it is like to get wet ever again! This possibility is becoming a reality now, thanks to the Ion-mask enhancement which is a new plasma technology that has been developed by P2i, a company under the wing of the UK’s Ministry of Defence.

New Technique To Find Hidden Fingerprints

New Technique To Find Hidden Fingerprints 

A fingerprint, outlined with a black conducting powder, can be seen on this bullet.  

It’s a discovery that would make even Sherlock Holmes proud. British scientists have developed a new crime-fighting technique that allows police to lift fingerprints from bullets even if a criminal has wiped down a shell casing.
