Looking beyond tumour-inducing effects of cell phones

  The cell phone has become an integral part of our lives. Thanks to the multiple tasks that today's smartphones can handle, a cell phone is promoted more as "Life Companion" than a gadget.  Even among friends and colleagues it has become quite common to find individuals who are so attached to their cell phones that they ' cannot live without them ', feel anxious if left without their phones or feel this need to answer every call they receive on their phone.  This addiction to stay connected has become a favorite topic for research on how cell phone usage affects our day-to-day lives. Initial studies concentrated on how cell phone usage affected tasks such as driving.  Results from such studies promoted the imposition of restrictions on drivers but pedestrians were left free to use their phones during their commute. A recent study focusing on pedestrian cell phone usage now tell us that attention of cell phone users is so impaired that most users fai

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

The future of racing, Formula E

Racing away from the gasoline-guzzling and noise polluting sport of Formula 1 , is the new category of auto racing, Formula E . An all-electric-cars event is expected to begin in 2014 and promises to take us one step closer to the future of using cleaner , greener cars in our day-to-day lives. Staying true to their motto of using racing events as a platform for innovation and testing newer technologies, the FIA (  Fédération Internationale de l'Automobile ), motorsport's governing body, has recently given a 'go-ahead' to Formula E and you might get the first glimpses of these cars in action mid-way this year. Surprising as it may sound, electric cars have been around since the late 1800's and were quite popular in those days. However,  developments in technology used for internal combustion engines led to popularity of gasoline fuelled vehicles, which we use today. Fuel crisis and the impact of using fossil fuels on our environment has once again drawn o
