Chemists create clever rewritable paper

By - December 3, 2014 1 Picture
The paperless office – one of the promises of the new digital age – has not really eventuated. Instead, most organizations still print out large amounts of documents on paper that, according to the WWF, is being produced at around 400 million tons (362 million tonnes) a year and rising. So, wouldn’t it be great if we could just simply wipe off the print on paper and use it over and over again? Chemists at the University of California, Riverside (UCR) thought that this might be a good idea too, and have now created rewritable paper that can be printed on and erased more than 20 times before it needs to be discarded.

DIY gun folds and shoots paper airplanes

The ability to fold a reasonably functional paper airplane isn't something that everyone possesses. If you're one of those people, then perhaps this is what you need – a device that takes multiple flat pieces of ordinary paper, folds each one into an airplane, then shoots it into the air. Read More

"Magic" marker helps investigators in hunt for fingerprints

By - October 8, 2014 2 Pictures
A "magic" marker pen developed at the University of Leicester enables forensic experts, police and criminal investigators to quickly determine whether a receipt potentially containing fingerprint deposits is made of thermal paper, with another device then used to reveal the presence of any fingerprints. The devices come thanks to the work of the suitably-named Dr Bond, John Bond, from the University's Department of Criminology. Read More

Layered paper 3D printers: Full color, durable objects at a fraction of the cost

By - July 9, 2014 24 Pictures
Irish company Mcor's unique paper-based 3D printers make some very compelling arguments. For starters, instead of expensive plastics, they build objects out of cut-and-glued sheets of standard 80 GSM office paper. That means printed objects come out at between 10-20 percent of the price of other 3D prints, and with none of the toxic fumes or solvent dips that some other processes require. Read More

Recyclable coffee cup could save billions from ending up in landfill

By - July 3, 2014 1 Picture
Along with a timely hit of caffeine, takeaway coffee can deliver its fair share of environmental angst as the office trash can begins to brim with empty paper cups. But what if, instead of being carted off to landfill, these cups could be recycled up to seven times, much like newspapers and regular cardboard? According to UK-based inventor Martin Myerscough, a small difference in the way these cups are produced could significantly reduce the monumental waste generated by today's coffee-crazed society.

PaperLater lets you create your own internet-based newspaper

Tablets and e-readers may indeed have plenty of advantages over old-fashioned newspapers, but for many people, a touchscreen will just never measure up to the user-friendly simplicity of newsprint. That's why the UK-based Newspaper Club is launching its PaperLater service – it allows users to set aside web articles of their choice, which will be incorporated into a print newspaper that's delivered to their door.

Nanoscale research may help preserve Leonardo da Vinci’s vanishing portrait

By - June 4, 2014 1 Picture
A famous red chalk on paper drawing, widely accepted as a self-portrait of Leonardo da Vinci, is rapidly deteriorating from the effects of years of exposure to pollution, light, and heat. Worst of all, many centuries in unregulated and humid storage has led to extensive yellowing and browning of the paper. Recently, however, researchers from Italy and Poland have developed a new non-destructive, nano-level method to identify the root causes of the degradation and assist in planning appropriate conservation strategies.
