Sufferers of type 1 diabetes regularly need to inject themselves with insulin in order to regulate levels of sugar in their blood, a process that is invasive and requires particular care. But a new study conducted at the Rensselaer Polytechnic Institute suggests that more comfortable treatment methods may not be all that far away, with scientists remotely manipulating insulin production in mice using electromagnetic waves.  Read More

The Multi is still in development, and ThyssenKrupp expects to test the system in 2016 (Im...

Elevator design hasn't progressed very much during the past 160 years, and still comprises cabins which move vertically in a shaft supported by cables. This is inefficient and limiting, taking up a relatively large footprint and requiring people to wait a long time for the next lift. However, German conglomerate ThyssenKrupp has unveiled a revolutionary Willy Wonka-style elevator concept that allows several cabins to move both horizontally and vertically in the same elevator shaft, at the same time.  Read More

The Miito is an induction kettle that heats only the liquid you need (Photo: Miito)

We all know that you should boil only what you need in a kettle to avoid wasting energy, but overfilling is still very common. The Miito combats this problem by using induction heating to boil just the water you need.  Read More

The new RF circulator could revolutionize microminiature communications devices (Photo: Co...

In the world of electronic components, there are many devices out there that do their job well and reliably, but are almost never heard of – even though they may be vital to equipment that plays a role in our technology-driven lives. The radio frequency (RF) circulator is just such a device: it has simply done its job as a nondescript box of gubbins buried in radio communications systems, quietly directing radio frequency signals to the places they should go. Now researchers at the University of Texas have given the RF circulator a makeover. Not only is the new prototype smaller, lighter, and cheaper, it's also claimed to be easily adapted to different frequencies on the fly, which is something the old style circulator cannot do.  Read More

On the eve of the planned first landing on comet 67P/Churyumov-Gerasimenko, the European Space Agency (ESA) announced that the unmanned Rosetta orbiter carrying the Philae lander has recorded a "song" emanating from the comet. The electromagnetic melody was detected by the probe’s Rosetta Plasma Consortium, which is a suite of five instruments used to study 67P.  Read More

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

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
