Magic Matter

Remember when you learnt about the three states of matter - solid, liquid and gas - in school? Well, things are not so simple now. There are other states - plasma and Bose-Einstein condensate and superconductors. Superconductors are materials through which electricity can flow without any resistance once they are cooled below a certain critical temperature. Resistance leads to loss of energy. No resistance means no energy lost. It is not surprising, therefore, that there are immense practical applications of superconductivity.

Hocus focus

Surgery was not what it is before anaesthesia. It was a mad scramble to perform the procedure in the shortest possible time. One of the leading surgeons of London in the first half of the 19th century, Robert Liston, could do amputations in 28 seconds flat, or so his admiring contemporaries recorded. Several methods were used to induce some measure of painlessness during surgery.

Perhaps this is the most unromantic cohabitation in the living world. Nepenthes ampullaria, an unusual pitcher plant found on the islands of Southeast Asia, allows the worm of Xenoplatyura beaveri, a species of fungus, develop and grow inside the plant's mouth.

When stars were born

It was morning in the universe and much colder than anyone had expected when light from the first stars began to tickle and excite their dark surroundings nearly 14 billion years ago.
