Laser un-printers could help save the trees

Laser 'un-printers' would allow paper to be re-used, reducing the need for virgin wood pulp

If you're concerned about deforestation, you likely blue-bin the no-longer-needed sheets of paper that have been run through your printer. You should keep in mind, however, that even though the recycling of that paper saves trees, the process still requires considerable energy, and most recycled paper still contains some virgin wood pulp. What would be better is if there were an "un-printer" that took the toner off of the used paper, so you would be left with a blank sheet that you could reuse. Well, thanks to research being conducted at the University of Cambridge, there soon may be.

New tech could allow drone aircraft to recognize deck crews' arm signals

Aircraft carrier deck crews may one day be able to direct autonomous drones, using standard arm signals

We’ve all seen footage of flight crews on the decks of aircraft carriers, directing taxiing planes using arm signals. That’s all very well and good when they’re communicating with human pilots, but what happens as more and more human-piloted military aircraft are replaced with autonomous drones? Well, if researchers at MIT are successful in one of their latest projects, not much should change. They’re currently devising a system that would allow robotic aircraft to understand human arm gestures.

Super accurate nuclear clock proposed

The Weltzeituhr (World Clock) at Alexanderplatz, Berlin, Germany isn't anywhere near as accurate as the nuclear clock proposed by researchers

The NIST-F1 atomic clock that currently serves as primary time and frequency standard for the U.S. is expected to neither gain nor lose a second in more than 100 million years. That might sound pretty accurate, but a proposed nuclear clock could make it look like a cheap digital wristwatch. It is claimed that the proposed clock would neither gain nor lose 1/20th of a second in 14 billion years. To put that in context, that’s the estimated age of the universe.

GameGadget handheld puts classic games in the palm of your hand

The GameGadget is a mobile gaming console designed for classic games titles

It wasn’t so long ago that the mobile gaming space was dominated by Nintendo and Sony. While both companies continue to stake a claim for the mobile gaming pie with the release of their latest handhelds – the 3DS and PlayStation Vita – dedicated mobile gaming consoles have been under serious fire from smartphones in recent years. But that hasn’t stopped a UK-based company entering the arena with the GameGadget – an open source console designed to let fans get their hands on classic games titles.

Review: The OPC musician's computer/amp from Orange Amps

Contents of the box: the OPC, wired keyboard and mouse, power cables, Quick start guide and USB extension cable

The first OPC from Orange Amps was made available in August 2010 and we've been closely following its development ever since. The bundled musician-related software has remained pretty much the same since launch but the musician's computer was given a serious hardware upgrade towards the close of 2011, and it's the new Core i7 system which I've been getting to know over the past few weeks. I've also managed to discuss some of the finer details with the driving force behind the OPC, and its lead developer, Charlie Cooper.
