Some lucky owners of the latest iPhone 5 have begun to regret their purchase. The fact is that the new device is made of aluminum - a rather flexible metal. So those who are used to keeping their CellPhones in the back pocket of their pants, the somewhat ‘flexible’ phones simply bent. So, this is when I ask the question: “How could it bend?”, as according to Apple, the screen is covered by tempered glass, which is scratch and it is extremely tough.
One of the main reasons that solar cells aren’t more efficient at converting sunlight into electricity is because much of that sunlight is reflected off the cell, or can’t be fully absorbed by it. A new sandwich-like material created by researchers at Princeton University, however, is claimed to dramatically address that problem – by minimizing reflection and increasing absorption, it reportedly boosts the efficiency of organic solar cells by 175 percent.

It was forty years ago this month that Apollo 17 took astronauts to the Moon for the last time. Since then, the satellite has only been visited periodically by unmanned probes, but that may change inside the next ten years. On Thursday, the day before the anniversary of Apollo 17’s launch, a new company called Golden Spike announced at the National Press Club that it would be sending commercial exploration missions to the Moon within a decade with a ticket price of US$750 million.
Once I was invited by a renowned public school of Rampur to speak to children about the core values of life. This is a subject dear to my heart and so I accepted the invitation and a programme was fixed accordingly. When I reached the school and spent a few minutes in the principal's office, I was cautioned by him that it was a difficult assignment for me, as children these days hardly understood the meaning of values. I was surprised to hear such a statement coming from the principal of a reputed school but took the advice in right perspective. It, however, had the effect of making me more determined to make my talk effective and I set my mind accordingly.
