Eco-friendly circuit board releases its electronics when exposed to hot water

As our smartphones and computers continue to become obsolete and get discarded, the environmental problem of electronic waste gets worse. Needless to say, the greater the number of electronic components that can be reclaimed and reused, the better. That’s why scientists from the UK’s National Physical Laboratory (NPL) have developed a printed circuit board that falls apart when immersed in hot water. Read More

Laser "sound visualizer" may lead to better loudspeakers

By - November 9, 2011 2 Pictures
We've been following the quest for the world's best speakers for some time but remarkably, there's still room for improvement. A key issue that plagues proper sound reproduction (and thus its perceived quality) is a phenomenon known as deconstructive interference. This occurs when audio signals overlap and cancel one another out, creating dead spots which, until recently, have been very difficult to track. Now, a team from Britain's National Physical Laboratory (NPL) has figured out a clever way to make speaker sound "visible" - and they do it with laser light. Read More
