Wireless charging, the future that's already here....

Comments from our readers, regarding the controversial car change in the proposed Formula E racing event , led us to further research about how could we recharge these cars quickly during pit-stops. Turns out, the best way to charge these cars, is not to stop at all. Charge them wirelessly (if that's an acceptable word), when in motion. Even better is the fact, that the technology already exists and is being actively implemented around us. Wireless charging can be achieved in a variety of ways, but the most effective so far, is when it is accomplished using electromagnets called inductive charging . Here, a charging station uses an induction coil to convert electric energy into an alternating electromagnetic field which the induction coil in the device we wish to charge takes up and converts back into electricity to charge batteries. Nikola Tesla was the inventor of this technology and you can read an interactive take on Tesla's under-advertised achievements in the post on

Eating - from casual to compulsive

What scientists call "Overweight" changes with our knowledge of human health (Photo credit: Wikipedia) In a world where we are battling addiction of some sort or the other, food is another item that has made the list. With the rising number of obese people around, scientists are looking for answer to questions that come up with eating , and one question that has made it to the fore is; when does the habit of eating move from being casual to compulsive.  To answer this question scientists had to dig deeper and look at the relationship that food has with not only our body, but also with our brain. What they found was nothing short of astonishing. Eating, it seems, is not very different from addiction to drugs. Our brain has opioid receptors that are receptive to opiates (substances such as heroin, morphine etc.) These molecules play an important role in motivation, emotional attachment, satisfaction etc. Our body produces similar proteins as well, which are know
