With a well established ability to kill off bacteria, silver has come to play a significant role in the development of antimicrobial materials. The latest effort comes from Australian researchers who have developed an antibacterial fabric capable of killing off infectious bacteria within 10 minutes.

While we've already seen folding bicycles that pack down into a tiny package, such bikes usually have at least one limiting factor – puny wheels that limit speed and road-worthiness. The Sada Bike, however, features full-size 26-inch hubless wheels, yet is about the size of an umbrella when folded.

At the INTERMAG Europe 2014 international magnetics conference in Dresden, Sony announced a new breakthrough in magnetic tape technology that keeps the medium relevant by allowing a tape cartridge to carry 74 times the data of a conventional data tape, or the equivalent of 3,700 Blu-ray discs.

The Ariel Atom's grown-up go-kart look and design are not for everyone. For those that want Atom-level performance with the styling of a full-fledged sports car, Rezvani presents the all-new BEAST. Ariel bones and organs get the skin of a proper sports car.

A team at Sweden's Mälardalen University is developing a virtual keyboard that combines a pair of bracelets with a wearable device such as Google Glass. The result is a keyboard that only its user can see.

In an Egyptian tomb, a painting depicts someone pouring water into the sand in front of one of the sledges that hauled the blocks used in the pyramids. According to new research, by wetting the sand, as little as half as much pulling force would have been required to move those sledges.

Scientists from Switzerland's Empa research group have come up with a method of using waste to contain pollution – they've developed sponges made from cellulose by-products, that can soak up 50 times their own weight in spilled oil.

Californian architecture and design studio MAT-TER has produced a concept for a flood-resistant school for the Philippines that's raised on piloti and constructed largely from bamboo.

Night Shift is a new device designed to help people with sleep apnea and snoring issues. These problems are aggravated by sleeping on the back, so the device, which is worn at the back of the neck, vibrates and prompts wearers to move position.

Researchers from the Harvard Stem Cell Institute (HSCI) have shown that injections of a protein dubbed GDF11, when administered to older mice, appear to cause a reversal of many signs of aging.

Peruvian scientists have installed an air-purifying billboard in the city of Lima, capable of doing the work of 1,200 trees and purifying 100,000 cubic meters of air daily.

At disaster sites such as building collapses, it's not uncommon to see trained dogs being used to sniff out trapped survivors. Now, thanks to a new "smart" harness, such dogs may be able to play an even bigger role, by gathering and relaying vital information on their surroundings.
