Japanese exoskeleton could help users walk and run, no batteries required

Assistive exoskeletons are a bit like electric bikes – they do indeed give users a power boost, but part of that boost is needed just to move the extra weight along. Japanese researchers at Hiroshima University and Daiya Industry Co., however, have created a minimalist exoskeleton that does away with heavy batteries and motors. Instead, their Unplugged Powered Suit (UPS) harnesses the wearer's own weight.

High-tech camera allows us to see invisible methane gas

Although methane is one of the most potent of the greenhouses gases, scientists still aren't entirely clear on all of its ground-based sources. That's why researchers from Sweden's Linköping and Stockholm universities have created a camera that's capable of imaging methane in real time. They say that it could find use in monitoring sources such as sludge deposits, combustion processes, farms and lakes.

New process allows inkjet printers to produce rainbow holograms

Credit card and banknote-style security holograms are an effective form of anti-counterfeiting technology, as they're very difficult to replicate. Every time a new batch is made, however, a "master hologram" has to be created first, to act as a template. These masters can take days to produce, using complex, expensive equipment. That could be about to change, however, as scientists at Russia's ITMO University have developed a quick-and-easy hologram production method that utilizes a regular inkjet printer.

KickSoul lets users control devices using their feet

As the engineers who developed Ford's kick-activated tailgate realized a few years ago, people tend to use their feet to perform tasks when their hands are full. Now, a team of researchers at the MIT Media Lab team has applied the same sort of thinking to the control of electronic devices. Their prototype KickSoul system lets users wirelessly control smartphones, computers and appliances using foot movements.

Bowley Lock promises high security at a low price

If the movies and TV are to be believed, picking a conventional lock is as easy as sticking a tool into a keyhole, thoughtfully moving it around for a few seconds, then pulling the door open with a crafty smile. While there are special high-security locks that are much harder to pick, they also tend to be quite expensive. That's why Canadian inventor Ryan Bowley created the Bowley Lock – it's claimed to be virtually pick-proof, yet affordable to the average home-owner.

Scientists turn gold into foam that's nearly as light as air

Along with its use in jewellery, gold also has numerous applications in fields such as electronics and scientific research. It's a handy material, but – of course – it's also expensive. That's why researchers at ETH Zurich have developed a new way of making a small amount of gold go a long way. They've created a gold foam that looks much like solid gold, but is actually 98 parts air to two parts solid material. As an added bonus, the aerogel-type foam can also be made in non-gold colors such as dark red.

Zombait brings new "life" to dead bait fish

When it comes to angling for big predatory fish, live bait is almost always the best way to go. Those bait fish must be caught and kept in a special "live well" aboard the boat, however, plus they'll inevitably tire out after spending much time at the end of the line. That's why Boston-based Magurobotics created the Zombait – it's a vaguely creepy device that makes dead bait fish move as if they're still alive.
