Red algae is a source of bacteria-killing lanosol (Photo: John Martin Davies)

Silver nanoparticles are very effective at killing bacteria, finding use in everything from water filters to non-smelly clothing. That said, there are some major concerns regarding the effects that those particles may have on human health and on the environment. Among other things, it has been suggested that they cause cell death, and compromise the immune system. Now, however, scientists at Sweden's KTH Royal Institute of Technology have come up with what could be a less harmful alternative – red algae.  Read More

The Relonch Camera works with the user's docked iPhone 5

Although there are already plenty of add-on lenses and apps that allow you to take better photos with your smartphone, they all ultimately still utilize the phone's existing lens and image sensor ... which typically aren't as good as those found on stand-alone cameras. The Relonch Camera, however, is designed to address that shortcoming. It's a proper camera that uses your docked iPhone as its brains.  Read More

The Lung Flute creates low-frequency sound waves that break up mucus in the user's lungs

Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is one of the most common causes of death in the US. Often the result of smoking, it's characterized by a restriction of the airways. Four years ago, a device known as the Lung Flute received FDA approval as a treatment for COPD. Now, a study conducted by the University of Buffalo has concluded that the hand-held device is indeed effective at helping patients breath more freely.  Read More

Quick Caps make it impossible to pull open a bike's quick-release wheel levers – without t...

While quick-release hubs certainly make it easier for cyclists to remove and reinstall their wheels when doing things like fixing flats, they also make it very easy to steal those same wheels. As a result, riders typically have to remove the front wheel when locking up their bike, or run a secondary cable lock from it to the main U-lock. Quick Caps, however, are designed to make doing so unnecessary – they're little padlocks for the quick-release levers.  Read More

Patrick Priebe's rocket-launching Iron Man gauntlet

By now, many regular Gizmag readers will be familiar with German cyberpunk weapons-hobbyist Patrick Priebe. We've featured a number of his one-off DIY creations before, including an Iron Man-inspired laser gauntlet. Well, now he's created another Iron Man gauntlet, although instead of just a burning laser, this one launches real rockets – and Priebe has already managed to hurt himself with the thing.  Read More

Residents of Qunu and Bushbuckridge will soon be getting free Wi-Fi from Coca Cola coolers... In this day and age, if a community is to prosper, it certainly helps if its residents have internet access. With that in mind, Coca-Cola South Africa has partnered with bottler Coca-Cola Fortune and communications company BT Global Services to provide underserved South African communities with free Wi-Fi ... which will be built into Coke vending machines.  Read More

MIT's prototype contraband-searching robot

Maritime smugglers will often hide contraband in false hulls or propeller shafts within their boats. While there are ways in which port authorities can search for such stashes, the smugglers often have time to ditch their illicit goods before those searches can be performed. However, what if there were stealthy, inexpensive, underwater hull-hugging robots that could check the boats out, without the crews even knowing they were there? That's just what a team at MIT is developing.  Read More

DHL's Parcelcopter can carry up to 1.2 kg (2.6 lb) of medication

Although big players such as Amazon, Google and the United Arab Emirates have all announced plans to launch drone-based delivery services, it looks like DHL Parcel is about to beat them to it. This week, the courier company announced that it will begin using its unmanned DHL Parcelcopter to deliver pharmaceuticals from the German seaside village of Norddeich, across 12 km (7.5 miles) of the North Sea, to the small island of Juist.  Read More

Georgia Tech's PR2 locates an RFID-labelled item

In order for household robots to be truly useful, it would be great if they could go and get items for you, without having to be shown where those things are. Thanks to research being carried out at Georgia Tech, that may someday be the case. A robot there is now able to search out hidden objects – as long as they've been labelled first.  Read More

If you're a bed bug, don't get into this suitcase

Although it's generally nice to bring things back from your travels, bed bugs would definitely not be among those things. That's why ThermalStrike luggage was created. It heats everything packed inside of it, to kill any unwanted stowaways.  Read More
