How safe is your fridge bottle?

In our day-to-day lives, we exercise extreme caution when it comes to drinking water. Water is treated at multiple points before it reaches your tap and even at home, we tend to use water purifiers that promise to kill 99.99% bacteria, viruses(?) and any other pathogen that might infect you. But have you ever wondered, how safe is the bottle that we store the water in? Multiple studies conducted have shown that the regular colourful fridge bottles, often made from polycarbonate (marked with a recycling code , 7) leaches Bisphenol A (BPA) into the water. BPA is the monomer that makes the polycarbonate plastic and hot or warm fluids usually result in depolymerization and release of BPA. This released chemical is very similar to estrogen and is capable of copying its function too. The Tolerable Daily Intake for BPA is 0.05 mg per kilogram of body weight per day. While this might be huge as compared to how much BPA actually leaches out, BPA has been associated with breast a

RECYCLING STEEL! totally rocks

Steel is created when iron is mixed with carbon and a few other compounds. It is one of the most versatile, man-made alloys, being used. We use steel for almost everything, from automobiles, ships and bridges to utensils, cutlery and jewellery. But, did you know that steel is one of the most environment friendly components, being almost 100% recyclable . According to a statistic from 2009 about 66.8% of the steel in the world was recycled that year.                                   White-hot steel pours like water from a 35-ton electric furnace, Allegheny Ludlum Steel Corp., Brackenridge, Pa.  (Photo credit: Wikipedia) Recycling of steel is not a new phenomenon. It was put into action years ago, and because it was more economical than mining iron ore and making fresh steel from it, recycling steel gained popularity over the years. More importantly, steel, on recycling, does not lose its inherent strength. So if you think of it, your fork and spoon may have someday been a

Music and the Brain

                                 Children at N.Y. Zoo (LOC) (Photo credit: The Library of Congress) If you thought music was just a means of entertainment, you are in for a surprise. Recent studies show that there is in fact a lot to music than what meets the “ear”. In recent years many acoustic experts and researchers have carried out experiments to show a correlation between brain function , cognition and music. One such experiment studied and compared the brain responses and sound recognition of pre-school children who were being trained in music to those who were not. It was observed that children who received musical training not only had better sound recognition but their auditory cortex appeared modified in comparison to the other group. The children also demonstrated enhancement in memory and attention level in comparison to the non- musical group . Musical training is also observed to have a remarkable impact on children suffering from dyslexia. Training in
