  Thanks to electricity, candles are no longer a necessity in our lives, but they are still a pleasure. The warm flame of candlelight can quickly alter the mood and atmosphere of a room, often creating a peaceful scene that electric light just cannot match.

  Candles are an important part of many cultural and religious festival and have been burnt in various forms for centuries. The ancient Romans and Egyptians made candles from a type of fiber coated with wax. However, up until the nineteenth century, most candles were made from a substance called tallow, obtained from beef fat. Tallow candles were very smoky and, understandably, had an unpleasant odor.

  In the 19^th century, candle makers learned to separate stearin, the solid form fat used as a type of glue, from tallow and used it to harden other fats. Candles that contained stearin would burn longer than previous ones and had a better smell. Stearin is still one of the main components of modern candle-making, and the techniques used to create candles today are much the same as they have been for many years. These days, the increase range of wax dyes, perfumes and other additives that are now available make candle making a very exciting and rewarding hobby.

   Sales of candles have increased greatly over the last few years, showing that they have become part of our lives again, not through necessity, but because of the magical atmosphere they create. In our increasingly stressful lives, the calming quality of candlelight has a relaxing effect that many enjoy.

  For those would like to learn to make candles, finding and buying candle-making kits is easy. Candle-making is definitely enhanced by the exciting possibilities of experimentation with various materials. Be brave and try out different effects – some of the most wonderful creations can happen by accident. With a bit of practice, you will be amazed at the very professional finish that can be achieved.

  Despite their delicate beauty, candles can, of course, be highly dangerous. One should never leave lit candles unattended, even for a few moments. Always make sure candles are securely placed within candleholders.

  Teach your children to respect a burning candle, and of course keep burning candles away from flammable materials. Keep your home safe by remembering that a candle is magical, but fire can be very destructive. Be careful, and enjoy the beauty of your candles!

   Pollution is a threat to many species on Earth, but sometimes it can cause species to thrive. Such is the case with Pfiesteria piscicida. A one-celled creature called a dinoflagellate, Pfiesteria inhabits warm coastal areas and river mouths, especially along the eastern United States. Although scientists have found evidence of Pfiesteria in 3,000-year-old sea floor sediments and dinoflagellates are thought to be one of the oldest life forms on earth, few people took notice of Pfiesteria.

  Lately, however, blooms – or huge, dense populations – of Pfiesteria are appearing in coastal waters, and in such large concentrations the dinoflagellates become ruthless killers. The blooms emit powerful toxins that weaken and entrap fish that swim into the area. The toxins eventually cause the fish to develop large bleeding sores through which the tiny creatures attack, feasting on blood and flesh. Often the damage is astounding. During a 1991 fish kill, which was blamed on Pfiesteria on North Carolina’s Neuse River, nearly one billion fish died and bulldozers had to be brought in to clear the remains from the river. Of course, such events can have a devastating effect on commercially important fish, but that is just one way that Pfiesteria causes problems. The toxins it emits affect human skin in much the same way as they affect fish skin. Additionally, fisherman and others who have spent time near Pfiesteria blooms report that the toxins seem to get into the air, where once inhaled they affect the nervous system, causing severe headaches, blurred vision, nausea, breathing difficulty, short-term memory loss and even cognitive impairment.

   For a while, it seemed that deadly Pfiesteria blooms were a threat only to North Carolina waters, but the problem seems to be spreading. More and more, conditions along the east coast seem to be favorable for Pfiesteria. Researchers suspect that pollutants such as animal waste from livestock operations, fertilizers washed from farmlands and waste water from mining operations have probably all combined to promote the growth of Pfiesteria in coastal waters.

What is the main function of the toxins emitted by the dinoflagellates?
