If the FITGuard glows green, the player should be OK

It's an ongoing problem within sports such as football and hockey ... players receive a severe blow to the head, yet they either don't realize that they've got a concussion, or they don't want to tell anyone so that they can keep playing. While there are already some helmet-mounted devices that detect and report such impacts, Force Impact Technologies' FITGuard is built into a mouthpiece – which the company claims is a better approach to take.  Read More

The Lunicycle features an elliptical wheel, offset cranks, and calf braces

Riding a unicycle is kind of like juggling or playing the bagpipes, in that it's infamously hard to master. While some people might say that that's the whole point in learning to do it, others just want to get riding that one-wheeled bicycle ASAP. If you're among the second group, then you might like Inventist's uniquely-designed Lunicycle.  Read More

Users of the NavVis mapping trolley don't have to hide from its cameras

When we first heard about the NavVis system a couple of years ago, it was being developed for indoor navigation. Developed by researchers at the Technical University of Munich, it utilizes maps consisting of location-tagged photos of the hallways of buildings. In order to figure out where they are, users just take a photo of their surroundings using their smartphone, then the NavVis app matches that photo up with one in its map. Now, the technology has been expanded to the point that it could give Google Street View a run for its money.  Read More

Sugar kelp yields a lot of bio-oil – if you put the heat on (Photo: NOAA)

Biofuels may indeed offer a greener alternative to fossil fuels, but they do raise at least one concern – crops grown as biofuel feedstock could take up farmland and use water that would otherwise be used to grow crops for much-needed food. That's why some scientists have looked to seaweed as a feedstock. Kelp is particularly attractive, in that it's abundant and grows extremely quickly, although its fuel yields haven't been particularly impressive. That could be about to change, however, thanks to a newly-developed hydrothermal process.  Read More

The ICE Full Fat is all set for your next 'big expedition'

Last December, British adventurer Maria Leijerstam became the first person to cycle from the edge of the Antarctic continent to the South Pole. She did so on a custom-built recumbent fat-tired tricycle, made by UK-based Inspired Cycle Engineering (ICE). Well, although there probably aren't many other people who want to do what Maria did, there no doubt are quite a few who'd like a trike like hers. That's why ICE is now offering the ready-for-anything Full Fat.  Read More

The Vello Urbano, folded for transit

Remember the baby stroller/scooter hybrid known as the Roller Buggy? Even if you don't, its Austrian creator is now part of the team behind another unique mode of human-powered transportation. This one's called the Vello bike, and it features a unique folding mechanism along with some other clever innovations.  Read More

The new phosphors can be tuned to emit a variety of colors, including a 'warmer' white tha...

Everybody loves LEDs, as they're far more efficient and longer-lasting than traditional incandescent bulbs. They're also more economical to use in the long run, although they're costlier on a per-bulb basis. That price gap could soon be closing, however, as scientists have discovered a cheaper alternative to one of their most expensive ingredients.  Read More

Cigarette ash could now have another use besides ... well, nothing (Photo: Shutterstock)

In a perfect world, cigarette waste simply wouldn't exist. Given that it does, though, scientists have explored a number of methods of repurposing it – these have included using compounds from cigarette butts to store energy, make shipping pallets, and rust-proof steel. Now, researchers have shown that cigarette ash can be used as a low-cost means of filtering arsenic from water supplies. It's a little ironic, as cigarette smoke actually contains a dangerous amount of arsenic.  Read More

The prototype device utilizes paraffin contained within thin aluminum plates

Although solar panels are active while the sun is shining, they typically don't do much once the sun goes down. This is why some systems incorporate water tanks. The water is heated during the day via the panels, then that stored thermal energy (heat) is used to warm the home at night. While the tanks are effective, they also take up a lot of space, making them difficult to fit into peoples' homes. A newly-developed device, however, stores just as much heat in half the space – using paraffin instead of water.  Read More

You can tell a lot about a dolphin by its breath (Photo: Shutterstock)

If you want to get a picture of wild dolphin populations' health, it's typically necessary to capture some of the animals and then obtain blood samples or skin biopsies. Needless to say, it's hard work, and the dolphins tend not to like it. Soon, however, it may be possible to gather the same information using a device that samples their breath.  Read More
