Body clock

On May 23 1989 Stefania Follini emerged from the cave at Carlsbad, New Mexico. She was a volunteer in an Italian research programme. The scientists in the programme were studying body rhythms. In that experiment Stefania, a 27-year-old decorator spent 130 days in the cave 30 feet underground.

During her time in the cave Stefania was completely alone except for 2 white mice. Her room was very comfortable but there was nothing to tell her the time. There were no clocks, watches, television or radio. There was no natural light and the temperature was constant at 21 degrees Celsius.

The results were very interesting. Her body clock was changed. Stefania spent more than 4 months in the cave. But she thought she had spent only 2 months. She was awake for 24 hours a day and she was sleeping for 10 hours. She ate fewer meals (she lost 7.72 kg in weight) and was rather depressed.

What was she doing and how did she spend her time in the cave? She was doing physical and mental tests. For entertainment she played cards, read books and listened to the music. She even learnt English from tapes.

The experiment was a success. It showed that our body clocks are affected by light and temperature.

Going for gold

Pure gold is rare. It is usually mixed with other metals. The proportion of gold is shown in carats. Pure gold is 24 carat and the cheapest is 9 carat. Most gold is found in South Africa (612 tons a year) and North America (459 tons a year). Gold is usually found in very small pieces or “nuggets”. The largest nugget, the Holtermann Nugget, was found in 1872 in Australia. It weighed 214 kilograms.

The largest reserves of gold are held in the USA in the Federal Reserve Bank and Fort Knox. The second biggest stores are held by the Bank of England and the bank of France. Not all of this gold belongs to the governments of these countries. A lot of it is owned by companies, other governments and individuals. Only the names on a piece of paper are changed. The gold itself stays in the bank.

The first gold coins were used in Turkey in 670 BC. But gold has always been accepted as money anywhere in the world. If they were shipwrecked, they could pay to get home again. Gold is still given to military pilots for the same reason.

How many crimes have been committed and how many lives have been lost for it? The gold of the Faraohs was stolen from their tombs in the Pyramids. The Inca and Aztec Empires were destroyed for gold.

Hundreds of men died in the jungles of South America as they searched for the golden city of Eldorado. In 1849 thousands of people left their homes to join the California Gold Rush. Many were killed by Indians, outlaws and disease.
