“A new theory that explains why the language of our genes is more complex than it needs to be also suggests that the primordial soup where life began on earth was hot and not cold, as many scientists believe.

…As the DNA ‘alphabet’ contains four letters – called bases – there are as many as 64 three-letter words available in the DNA dictionary. This is because it is mathematically possible to produce 64 three-letter words from any combination of four letters.

But why there should be 64 words in the DNA dictionary which translate into just 20 amino acids, and why a process that is more complex than it needs to be should have evolved in the first place, has puzzled scientists for the last 40 years.” (University of Bath.UK)

“Ounce for ounce, it costs more than gasoline, even at today’s high gasoline prices; depending on the brand, it costs 250 to 10,000 times more than tap water. Globally, bottled water is now a $46 billion industry. Why has it become so popular?

It cannot be the taste, since most people cannot tell the difference in a blind tasting. Much bottled water is, in any case, derived from municipal water supplies, though it is sometimes filtered, or has additional minerals added to it.

Nor is there any health or nutritional benefit to drinking bottled water over tap water. In one study, published in The Archives of Family Medicine, researchers compared bottled water with tap water from Cleveland, and found that nearly a quarter of the samples of bottled water had significantly higher levels of bacteria. The scientists concluded that ‘use of bottled water on the assumption of purity can be misguided.’ Another study carried out at the University of Geneva found that bottled water was no better from a nutritional point of view than ordinary tap water.

…Bottled water is undeniably more fashionable and portable than tap water. The practice of carrying a small bottle, pioneered by supermodels, has become commonplace. But despite its association with purity and cleanliness, bottled water is bad for the environment. It is shipped at vast expense from one part of the world to another, is then kept refrigerated before sale, and causes huge numbers of plastic bottles to go into landfills.

…Clean water could be provided to everyone on earth for an outlay of $1.7 billion a year beyond current spending on water projects, according to the International Water Management Institute. Improving sanitation, which is just as important, would cost a further $9.3 billion per year. This is less than a quarter of global annual spending on bottled water.

I have no objections to people drinking bottled water in the developing world; it is often the only safe supply. But it would surely be better if they had access to safe tap water instead. The logical response, for those of us in the developed world, is to stop spending money on bottled water and to give the money to water charities.

If you don’t believe me about the taste, then set up a tasting, and see if you really can tell the difference. A water tasting is fun, and you may be surprised by the results. There is no danger of a hangover. But you may well conclude, as I have, that bottled water has an unacceptably bitter taste.” — Tom Standage, author of A History of the World in Six Glasses and technology editor of The Economist (New York Times op-ed)
