The Veloloop mounts on the non-drive-side chain stay

If you're a regular bicycle commuter, then you've no doubt experienced the following scenario: you're the only vehicle going in your direction at a controlled intersection, and the light is red, but it won't change to green because the traffic sensors embedded in the asphalt can't register your presence. Well, that's where the Veloloop comes in. It's designed to make those sensors think that your bike is a car.  Read More

An F/A-18C Hornet is launched from a test runway using EMALS (Image: US Navy)

A fighter plane taking off from a strike carrier is a dramatic sight – not the least because of the woosh and plume of steam as the catapult blasts the aircraft into the air. In a few years, such launches may still be dramatic, but they’ll also be a bit quieter and very plume-free. That’s because the US Navy has completed testing of its Electromagnetic Aircraft Launch System (EMALS); clearing it for use on the new Gerald R Ford-class aircraft carriers.  Read More

A new technique can detect terahertz waves at room temperature quickly and accurately (Ima...

Researchers at the University of Michigan have found a way to accurately detect electromagnetic waves in the terahertz range by first converting them into sound. The advance opens up new applications ranging from tighter airport security to safer medical imaging.  Read More

Hyperspectral imaging is a bit like super-vision. With it, you can not only see what’s there, but what it’s made of, which is a good thing if you’re looking for bombs, gas leaks, and smuggled nuclear material. Defense and information systems specialist Exelis has announced the successful test of a new airborne long-wave infrared (LWIR), hyperspectral (HSI) sensor that can be aimed in multiple directions and is capable of detecting explosives, gases and dangerous chemicals.  Read More

'La Fenice' makes both traditional Italian espresso and American filter coffee and uses up...

A team of young Italian coffee aficionados has come up with a new concept for a coffee machine, which they claim to be the world's first electromagnetic induction coffee maker. Dubbed "La Fenice," the fully functional prototype makes both traditional Italian espresso and American filter coffee and uses up to 80 percent less energy than most other coffee machines.  Read More

The technology is also built into Kohler's new Cimarron Touchless Toilet

When it comes to things that the germ-conscious want to avoid touching, toilet flush levers likely occupy the top spot. Kohler evidently realizes this, as it now offers a retrofit kit that allows buyers to flush their existing toilet without touching it.  Read More

Lunecase runs off of electromagnetic energy emitted by the iPhone

Smartphone cases are so common that you can pick one up at the supermarket checkout stand, so for one to stand out, it needs something more than a print of a cartoon kitten. Built by Concepter, a company based in Kiev, Ukraine, the Lunecase is s a batteryless, wireless phone case that not only interacts with an iPhone, but also powers itself from the electromagnetic radiation emitted by the device.  Read More

The technology could allow antennas to fit seamlessly into the skins of aircraft and other...

Anyone who’s ever needed a pair of thick eyeglasses has a firm idea that lenses are the one thing where form follows function. However, BAE Systems and Queen Mary’s School of Electronic Engineering and Computer Science in London have put paid to that idea with a flat lens that works like a conventional curved lens, yet without any reduction in bandwidth performance. Using a combination of composite metamaterials and transformational optics for the first time, they have created a lens that's able to bend electromagnetic waves, yet isn't bound by its shape for its function.  Read More

Patrick Priebe's electromagnetic webshooter

In honor of The Amazing Spider-Man 2 opening tomorrow in Germany (among other places), German laser weapons hobbyist Patrick Priebe has just filled us in on his latest creation – it's a Spider-Man-inspired electromagnetic webshooter, that actually fires a harpoon-tipped length of fishing line into styrofoam targets.  Read More

The Cefaly headband is claimed to not only treat migraines, but help to reduce their frequ...

Though using electrical stimulation of the brain as a means of treating migraines has provided an alternative to over-the-counter medication, the administering of the electrical currents can be complex, involving bulky equipment or even surgically implanted electrodes. Cefaly, a battery-operated headband, has now been approved by FDA (US Food and Drug Administration) and is said to not only treat migraines, but possibly prevent them altogether.  Read More
