Cancer that forms in the thyroid gland (an organ at the base of the throat that makes hormones that help control heart rate, blood pressure, body temperature, and weight). Four main types of thyroid cancer are papillary, follicular, medullary, and anaplastic thyroid cancer. The four types are based on how the cancer cells look under a microscope.

end of the spectrum are the reds and oranges. These gradually shade into yellow, green, blue, indigo and violet. The colors have different wavelengths, frequencies, and energies. Violet has the shortest wavelength in the visible spectrum. That means it has the highest frequency and energy. Red has the longest wavelength, and lowest frequency and energy. LIGHT IN THE AIR Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits. Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors. Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the co

As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

ORIGIN OF THE CELEBRATION Section: Festival The start of the New Year has been celebrated in China for more than 3,000 years. New Year was a time when the farmers gave thanks for the harvest and prayed to the gods for a good harvest in the coming year. This was the one period in the busy farming year when there was time to have a celebration and when the family could get together, relax, and be merry. Chinese New Year begins with a New Moon. The Lunar Year is calculated from the time it takes for the Moon to travel around the Earth, while the Western (Gregorian) calendar is based on the time it takes for the Earth to circle the Sun. The orbits of the Moon bear no relation to the time it takes for the Earth to go around the Sun, which is why the Chinese Lunar New Year is celebrated on a different date each year. In China the New Year was renamed the Spring Festival, in 1911, when the Western calendar was officially accepted in China. However, it is still commonly known around the world as the Chinese New Year. Chinese years are named after one of twelve animals. These have been used in the same order to name the years since the sixth century A.D. Each animal is said to have its own personality and emotions, which are present in people born within its year. ~~~~~~~~By Sarah Moyse This article is copyrighted.

RELIGIONS AND RITUALS Section: Festival Although the New Year celebration is not mainly a religious one, many Chinese will visit a temple at this time of the year to make an offering to the Buddha or to the gods in the hope of making the New Year a good one. Ancestors and gods are honored with ceremonies in the home around a family altar decorated with flowers. Incense and candles are burned at the altar. At important family banquets the ancestors may be recognized as "spiritual guests" and first offered food that is afterward eaten with the meal. The Chinese have three main systems of ideas that are important to them: Confucianism, Daoism, and Buddhism. Although these systems are very different, many Chinese follow some or all of the rituals associated with them just to be safe. Confucius lived in the fifth century B.C. and spoke about the value of good behavior in private life and in government. He said that politeness, honesty, courage, and loyalty were what made good people. He believed in self-development through education and thought that people gain in wisdom as they grow older. It is part of the Confucian tradition to honor parents and ancestors.

Daoism comes from the teachings of Laozi, who lived at the same time as Confucius. His book, the Dao De Jing (The Way and Its Power), describes the way (dao means "way") to live at peace with nature so as not to upset natural balances. The Way involves balance between opposite forces. They are called yin and yang. While yin is dark and female, yang is the opposite, being light and male. When yin and yang are balanced, there is perfect harmony with nature. Unlike Confucianism and Daoism, which started in China, Buddhism came from India and is based on the teachings of the Buddha -- a holy man. Buddha taught that people need to let go of earthly desires and become fully aware of what they are doing in the present. Buddhists believe that after death each soul moves on to another body, which may be animal or human. What one is chosen for in the next life depends on how good or bad the person has been in this life. The Chinese also pray to other gods, holding the view that the more gods who can look after them the better. The important ones are the Kitchen God, who watches the family in the home, the Jade Emperor, who is the most important god in heaven, the God of Wealth, who determines how wealthy people are, and the Door Gods. ~~~~~~~~By Sarah Moyse This article is copyrighted.

Born on January 4, 1809, Coupvray, France, Braille was accidentally blinded in one eye at the age of three. Within two years, a disease in his other eye left him completely blind.

Captain Charles Barbier invented sonography, or nightwriting, a system of embossed symbols used by soldiers to communicate silently at night on the battlefield. Inspired by a lecture Barbier gave at the Institute a few years later, the fifteen-year-old Braille adapted Barbier's system to replace Haüy's awkward embossed type, which he and his classmates had been obliged to learn.

In his initial study, Braille had experimented with geometric shapes cut from leather as well as with nails and tacks hammered into boards. He finally settled on a fingertip-sized six-dot code, based on the twenty-five letters of the alphabet, which could be recognized with a single contact of one digit. By varying the number and placement of dots, he coded letters, punctuation, numbers, diphthongs, familiar words, scientific symbols, mathematical and musical notation, and capitalization. With the right hand, the reader touched individual dots and, with the left, moved on toward the next line, comprehending as smoothly and rapidly as sighted readers. Using the Braille system, students were also able to take notes and write themes by punching dots into paper with a pointed stylus which was aligned with a metal guide.

t is a basic notion that during the 1600's, accurately in the year 1621, the English settlers and the Wampanoag Indians got together and shared a fantastic fall harvest feast to celebrate the bounty from the rich earth. Today this celebratory feast is acknowledged to be one of the first Thanksgiving festivities in the early days of the colonies. While that long ago feast is supposed by a lot of people to be the first Thanksgiving celebration, it was, in fact, part of a long existing custom of celebrating the seasonal harvest and giving thanks for a good bounty of crops that would last through the long hard winter. Many Native American tribes of what would be named America, including the Pueblo, Cherokee, Shawnee, Huron, Creek, Blackfoot and so many others would hold huge harvest festivals, consisting in ceremonial dances, races, games and other cheerful celebrations of gratefulness hundreds of years before the European peoples arrived. If you are like me, you are surely wondering the kind of meals served at the harvest feast. Historians, as usual, are not one hundred percent sure regarding it; however they are sure that pilgrims weren't eating pumpkin pies nor building castle towers with mashed potatoes. However, it is easy to think that the list of meat available during this period of time should surely include venison as well as several types wild poultry such as duck, goose as well as wild turkey. While there are hundreds of manuscripts describing such feast, the most detailed description of this celebration of late harvest date of 1621 and was written by a man called Edward Winslow. It is from his manuscript called "A Journal of the Pilgrims at Plymouth" that historians have gleaned the greatest part of information about this first Thanksgiving celebration:

Although the first Thanksgiving dinners were not concentrated on the turkey; today's usual meal primarily focuses around this animal. During the 17th century, vegetables were not as important as of today, so the meal of this period of time included a lot of different meats. The many types of vegetables we take for granted today were not available to the colonists. Freezing methods did not exist; which means that the vegetable consumption was based on seasonal harvests. Because the colonists and Wampanoag tribe had no refrigeration in the 1600s, they dried a lot of their foods to preserve them. They would dry corn, wild boar hams, fish, venison, and many wild herbs.

Though it sounds like a classroom assignment from Hogwarts School of Witchcraft and Wizardry, weather modification programs have been around for more than 50 years.

The problem is there are too many factors that affect the weather, making naturally occurring phenomena difficult to separate from man-made triggers.

"There was no strong scientific base for changing the weather."

n experiments, the cream-based ultra-violet (UV) filters -- used to protect skin from the harmful effects of sun exposure -- caused bleaching of coral reefs even in small quantities, the study found.

But some 60 percent of these reef systems are threatened by a deadly combination of climate change, industrial pollution and excess UV radiation.

The new study, published in U.S. journal Environmental Health Perspectives, has now added sun screens to the list of damaging agents, and estimates that up to 10 percent of the world's reefs are at risk of sunscreen-induced coral bleaching.

The Pilgrims were English Separatists. In the first years of the 17th century, small numbers of English Puritans broke away from the Church of England because they felt that it had not completed the work of the Reformation. They committed themselves to a life based on the Bible. Most of these Separatists were farmers, poorly educated and without social or political standing. One of the Separatist congregations was led by William Brewster and the Rev. Richard Clifton in the village of Scrooby in Nottinghamshire. The Scrooby group emigrated to Amsterdam in 1608 to escape harassment and religious persecution. The next year they moved to Leiden, in Holland where, enjoying full religious freedom, they remained for almost 12 years. In 1617, discouraged by economic difficulties, the pervasive Dutch influence on their children, and their inability to secure civil autonomy, the congregation voted to emigrate to America. Through the Brewster family's friendship with Sir Edwin Sandys, treasurer of the London Company, the congregation secured two patents authorizing them to settle in the northern part of the company's jurisdiction. Unable to finance the costs of the emigration with their own meager resources, they negotiated a financial agreement with Thomas Weston, a prominent London iron merchant. Fewer than half of the group's members elected to leave Leiden. A small ship, the Speedwell, carried them to Southampton, England, where they were to join another group of Separatists and pick up a second ship. After some delays and disputes, the voyagers regrouped at Plymouth aboard the 180-ton Mayflower. It began its historic voyage on Sept. 16, 1620, with about 102 passengers--fewer than half of them from Leiden.

Holidays are very important to the French. The French begin the year with a celebration of the Jour de l'An, which is New Year's Day. They greet each other by saying "Bonne Annee!" (Happy New Year). On January 6th there is la Fete des Rois (the Festival of the Three Kings), where people have a King's Cake. Whoever finds the special toy that has been baked into the cake gets to be king or queen for the day. In February, the French celebrate la Saint-Valentin or Valentine's Day by giving, valentines and chocolates. Also the French mark the start of Lent (a religious time when people fast) with Mardi Gras celebrations. On the 1st of April people play tricks on each other and say "Poisson d'avril!" which means "April fish!" People have little paper fishes that they cut out and try to stick on the backs of their friends that day. Easter is an important holiday in France. On the morning of Easter Sunday, most French people go to church. Afterwards, they carry home candles that have been blessed by priests. For Easter, which is called Le Pacques, omelettes, (an egg dish) are usually eaten for breakfast. People also give each other chocolate eggs and chocolate bunnies.
