Whether caused by strokes in seniors or hypoxia in newborn infants, brain injuries can cause the brain to overheat, which in turn causes its cells to die. While there are cooling therapies that can bring its temperature down, doctors first need to establish that the brain is indeed warmer than the rest of the patient’s body. While doing so has previously involved invasive techniques, researchers from Children's Hospital of The King's Daughters (CHKD) in Norfolk, Virginia have recently created a small device that sits on top of the patient’s head, and measures their brain’s temperature non-invasively.

It has been estimated that over 8 billion US gallons (30.3 billion liters) of used motor oil are produced every year by the world’s cars and trucks. While some of that is re-refined into new oil or burned in furnaces for heat, neither of those processes are entirely environmentally-innocuous. In other cases, it is simply discarded. Today, however, researchers from the University of Cambridge announced the development of a process that uses microwaves to convert waste oil into vehicle fuel. Read More
A research team from the Missouri University of Science and Technology (Missouri S&T) has succeeded in creating a portable scanning system that's capable of looking inside objects or structures and revealing hidden secrets. Using technology similar to that used for full body scans at airports, the new transmission mode camera system can detect, collect, process and display millimeter-wave and microwave signal information in real time and at adjustable focus points between the transmitter and collector aperture. The whole setup is powered by a single laptop-sized battery, with the results being displayed on a notebook screen. Read More
The first complete microwave image of the Moon taken by Chinese lunar satellite Chang'E-1 has been revealed. Chang’E-1 is China’s first scientific mission to explore planetary bodies beyond Earth and the on-board Lunar Microwave Radiometer has made it possible for the first time to globally map the Moon in microwave frequencies. Radar observations of the Moon are unable to provide thermal information, and microwave observations taken from Earth cannot reach the far side of the moon. So Chang'E-1's (CE-1) orbit was conducted at an altitude of 200km (124 miles) and allowed it to observe every location of the moon with a nadir view and at high spatial resolution. Read More
Sharp has announced the new Steamwave AX-1100, a 3-in-1 steam oven with a combination of steamer, grill and microwave. The Steamwave follows the success of Sharp’s Superheated Steam Oven and is one of the first multiple ovens to introduce steam and grill to a microwave unit. Given that many households these days are centered around becoming more health conscious, the idea of having easy access to a steamer and grill will most likely prove popular. Read More
Researchers at Southeast University in Nanjing, China have created a device that traps and absorbs electromagnetic waves coming from all directions, spiraling them inwards without any reflections, essentially creating an electromagnetic black hole. Qiang Cheng and Tie Jun Cui’s “omnidirectional electromagnetic absorber” draws in microwaves coming from any direction by spiraling radiation inwards, and converting its energy into heat. They plan on developing a device that can absorb visible light next. Read More
The impact of the microwave oven on human grazing habits has been extreme. It can reheat frozen food or cook raw food in a fraction of the time required of a conventional oven and has brought the convenience of preparing food to new levels. Now a portable microwave oven offers those same capabilities to people who need to prepare food away from the kitchen, or indeed off-the-grid entirely – truckies, RVers, boaties, campers … . The US$250 WaveBox weighs just 6.3 kg (14 pounds), runs on mains voltage regardless of country, and can also run from a 12 volt battery using alligator leads or from your in-vehicle power outlet. This is without doubt a killer app! Read More
There’s no doubting the time saving convenience of microwave ovens. But what about the time wasted because of them? Their super fast cooking means there really isn’t enough time to go and do something else while we wait for our food, so we find ourselves loitering around watching the seconds tick down. A couple of researchers from Japan’s Keio University have come up with the perfect solution for those of us who need to be entertained at every minute of every day in the form of the CastOven, which lets users enjoy a bite-sized piece of YouTube goodness while they wait for their food.

Researchers in the U.K. are working at turning newly developed imaging technology into an intelligent harvesting machine. Using microwave measurement, the system can look beneath the leafy layers of a crop, identify the differing materials, and enable precise size identification. Such a machine could minimize wastage in crops like cauliflower and solve an impending labor shortage for U.K. farmers caused by a fall in the number of migrant workers. Read More
Heinz, famous the world over for its ketchup and baked beans, claims to have come up with a quick and easy solution for the legions of stressed out workers who are missing out on meals because they are tied to their desks. A portable microwave oven amusingly called the Beanzawave might not sound that impressive, but add its miniature dimensions and USB connectivity to the mix then this could be a recipe for success.
