In the late 1970s, another type of rock called New wave music became popular. Bands such as INXS and Midnight Oil from Australia became popular. In the United States, New Wave bands such as Talking Heads and Devo played. In the 1980s, New Wave music bands such as Duran Duran, A Flock of Seagulls, Psychedelic Furs, and the Eurythmics were popular. These bands used the synthesizer keyboard a lot in their songs.
In the 1980s, a new type of rock and roll was invented, called glam metal. Glam metal rock bands mixed pop music with heavy metal music. Glam metal bands such as Mötley Crüe, W.A.S.P. and Ratt became popular. Glam metal rock bands had long hair and the men wore make up and leather pants and boots. Many glam metal songs were about sex, illegal drug use, and drinking alcohol. In the late 1980s, groups such as Guns N' Roses were very successful.
Another rock music trend from the 1980s was alternative music. Bands such as R.E.M., Sonic Youth, The Smiths, Pixies, Hüsker Dü, The Cure, and others were popular with teens and young adults. The most immediate type of alternative music was "grunge," a combination of punk, rock and metal. Proponents of grunge included Nirvana, Alice in Chains, Soundgarden and Pearl Jam with themes of sadness and loneliness.

Thomas Edison
Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and entrepreneur, who invented many things. Thomas Edison developed one of the first practical light bulbs, but contrary to popular belief did not invent the light bulb. Edison's 1093 patents were the most granted to any inventor in his time. He started the General Electric Company to make some of the things he invented.He died due to a disease called 'Diabetes mellitus'.
Thomas Alva Edison was born in Milan, Ohio. When Edison was seven years old, he moved with his family to Port Huron, Michigan. Edison started school late because of an illness. Three months later, Edison was removed from school, because he could not pay attention to his teacher. His mother, who was a teacher in Canada, taught Edison at home. Edison's mother helped him become motivated for learning, and he was a good student to her.
When Edison was twelve years old, he contracted scarlet fever. The effects of the fever, as well as getting picked up by the ears by a train conductor, caused Edison to become completely deaf in his left ear, and 80 percent deaf in the other. He learned Morse code of the telegraph, and began a job as a "brass pounder" (telegraph operator). At age sixteen, Edison made his first invention, which was called an "automatic repeater." It used punched tape to send telegraph signals quickly between unmanned stations, more quickly than a telegraph operator could do.
In 1868, Edison moved East and began to work for the Western Union Company in Boston, Massachusetts as a telegraph operator. He worked twelve hours a day, six days a week, and continued to "moonlight" on his own projects. Within six months, he had applied for and received his first patent for an electric vote recorder. It made the voting process faster but he could not find buyers. Then, Edison moved to New York and began to work for a company fixing their machines. At night, he continued to work on his projects.
In 1876 Edison used the money from his inventions to start his own laboratory in Menlo Park, New Jersey. In 1877~78, he invented there the carbon microphone, which made the sound for Alexander Graham Bell's new telephone invention louder. In 1877, Edison invented the phonograph, the first machine that could record and play sound. The phonograph made him internationally famous. How ever a new discovery proved that the French inventor Édouard-Léon Scott de Martinville invented sound recording before Edison. In 1879, Edison made a light bulb that lasted longer. Another invention, the electric power distribution network, lasted even longer.
He married Mary Stilwell in 1871. He had three children in that marriage: Marion Estelle Edison (also called Dot), Thomas Alva Edison, Jr. (also called Dash) and William Leslie Edison. Mary Stilwell died in 1884. Thomas Edison bought some land in Florida and built a house. When he was thirty-nine, Edison married his second wife, Mina Miller, who was 19. He had 3 children in that marriage: Madeleine Edison, Charles Edison (who took over the company when his father died and was later elected Governor of New Jersey), and Theodore Miller Edison.
Diabetes mellitus
Diabetes is a condition that results from lack of the hormone insulin in a person's blood, or when the body has a problem using the insulin it produces ("insulin resistance"). There is another disease with a similar name, diabetes insipidus, however, they are not related. When people say "diabetes", they usually mean diabetes mellitus. People with diabetes "Mellitus" are called "diabetics".
Glucose is not regular sugar that is available in stores and supermarkets. Glucose is a natural carbohydrate that our bodies use as a source of energy. The kind of sugar sold in supermarkets is called sucrose, and is much different from glucose. High concentrations of glucose can be found in soft drinks and fruits.
The glucose level in the blood is controlled by several hormones. Hormones are chemicals in the body that send messages from cells to other cells. Insulin is a hormone made by the pancreas. When you eat, the pancreas makes insulin to send a message to other cells in the body. This insulin tells the cells to take up glucose from the blood. The glucose is used by cells for energy. Extra glucose that is not needed right away is stored in some cells as glycogen. When you are not eating, cells break down the stored glycogen into glucose to use as energy.
Type 1 diabetes Mellitus happens when the part of the pancreas that makes insulin is destroyed by that person’s own immune system. When the pancreas does not make insulin, glucose – sugar – in the blood cannot get into the parts of the body that need sugar to live. In order to live, a person with type 1 diabetes must take insulin for the rest of their life. They need to check their blood sugar level on a regular basis, often, many times each day.
Type 1 diabetes happens most of the time in younger people, however, it can occur in adults, although this is much less common. About 1 out of every 10 people with diabetes have type 1 diabetes.
Type 2 diabetes Mellitus is an illness very different from type 1 diabetes. In type 2 diabetes, the person makes insulin, but either the insulin does not work in that person’s body as it should, or they do not make enough insulin to process the glucose. When insulin does not work as it should, glucose (sugar) in the blood cannot get into the parts of the body that need sugar.
Gestational diabetes mellitus is like type 2 diabetes. It happens to some women when they are pregnant.
Other types of diabetes include but are not limited to:
Type 2 diabetes happens most of the time in an older person who is overweight.
The onset of symptoms in type 1 diabetes usually happens suddenly. In type 2 diabetes, there may be mild symptoms or no symptoms at all. Making it much harder to detect.
Complications are problems that happen because of a disease. In the case of diabetes, there are two kinds of complications. The first kind happens quickly and can be dealt with quickly. This kind is called an "acute complication". The other kind is caused by the blood glucose being too high for many years, and is called a "chronic complication" or "long-term complication".
