New research shows that hair turns grey as a result of a chemical chain reaction that causes hair to bleach itself from the inside out. The process starts when there is a dip in levels of an enzyme called catalase. Catalase shortfall means that the hydrogen peroxide that naturally occurs in hair can’t be broken down. So hydrogen peroxide builds …

Albert Einstein considered the idea of quantum entanglement, like much of quantum physics, to be ridiculous. The phenomenon asserts that two particles can be connected so that changes in one are instantly reflected in the other, even if those two particles are light-years apart. Despite its strangeness, reports of entanglement have been well-documented. Known as ‘the God effect’, entanglement is …

Making A Crazy Path in the Garden A crazy path gives your garden an old-world appearance which is very pleasing. Most people construct such paths out of odd-shaped pieces of flag-stones; but the varying thicknesses of the pieces gives the path an uneven tread, which makes walking not at all easy.

Just drop them down somewhere, one of top of the other, preferably on a stretch of the lawn, up near one corner. Drive four wooden stakes into the ground inside the covers and equidistant, …

A voltage stabilizer is an electrical appliance used to feed constant voltage current to electrical gadgets like ACs and computers, and protects them from damage due to voltage fluctuations. It works on the principle of a transformer, where the input current is connected to primary windings and output is received from secondary windings. When there is a drop in incoming …

Nesting Boxes Fifteen years ago we built a nesting box and hung it on a tree in a shady spot of the garden where cats could not reach it. During every one of those fifteen years it had been tenanted by blue tits. These feathered visitors have made a welcome addition to the garden, which most of us would appreciate. …

The Marathon is a long, gruelling race which traditionally closes the Olympic events. It is taken from the amazing achievement of the Greek runner Pheidippides, who ran over twenty-six miles in four hours, taking news to Athens of the Persians’ defeat at the Battle of Marathon in 490 BC.
