An Amazing Invention
Look at your hand, and it might not seem very interesting at first, but it is an amazing tool. In fact, the human hand is as complex and as useful as a high tech machine. This might sound strange to you, but the development of the human hand changed the world. For example, the thumb helped human beings become the smartest and most powerful animals on the Earth. Your thumb is important because it faces your other fingers. This allows you to hold things, like tools. Being able to hold tools allowed our ancient ancestors to build things and become more advanced. It is also possible that when we developed thumbs and started to use tools, our brains developed faster as well. And how about this? Your fingers are the only parts of your body that are moved by a “remote control”. A remote control is the small device that you use to change the channel on your television. Your fingers are controlled by remote because they don’t have any muscles. You control your fingers with the muscles in your palms. The palms are connected to the fingers by tendons. The palms pull the tendons, and move them the same way a string moves a puppet. Every part of the human body is complicated, but the hand is especially complicated. It has a total of 29 bones. There are 34 different muscles that move the fingers and the thumb. Seventeen of those muscles are in the palm, and 18 are in the forearm. The human hand also has 48 nerves and 30 arteries. An artery is like a vein, but it carries blood away from the heart. Human beings are not as strong or as fast as other animals. However, our ancient ancestors were able to rule the world for two reasons.  First, they were intelligent. Second, they had these amazing instruments called hands. There is no other invention like them in the world.

Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person's diet. This translates to about 75- 100 grams of carbohydrates per day. A diet that is deficient in carbohydrates can have an adverse effect on a person's health. When the body lacks a sufficient amount of carbohydrates it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a buildup of ketones in the body that causes fatigue, lethargy, and bad breath.

During the nineteenth century, women in the United States organized and participated in a large number of reform movements, including movements to reorganize the prison system, improve education, ban the sale of alcohol, and, most importantly, free the slaves. Some women saw similarities in the social status of women and slaves. Women like Elizabeth Cady Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both women and blacks. A number of male abolitionists, including William Lloyd Garrison and Wendell Philips, also supported the rights of women to speak and participate equally with men in antislavery activities. Probably more than any other movement, abolitionism offered women a previously denied entry into politics. They became involved primarily in 20 order to better their living conditions and the conditions of others. When the Civil War ended in 1865, the Fourteenth and Fifteenth Amendments to the Constitution adopted in 1868 and 25 1870 granted citizenship and suffrage to blacks but not to women. Discouraged but resolved, feminists influenced more and more women to demand the right to vote. In 1869, the Wyoming Territory had yielded 30to demands by feminists, but eastern states resisted more stubbornly than before. A women's suffrage bill had been presented to every Congress since 1878 but it continually failed to pass until 1920, 35 when the Nineteenth Amendment granted women the right to vote.

Aspirin's origins go back at least as early as 1758. In that year, Englishman Edward Stone noticed a distinctive bitter flvor in the bark of the willow tree. To Stone, this particular bark seem to have much in common with "Peruvian Bark", which had been used medicinally since the 1640s to bring down fevers and to treat malaria, stone decided to test the effectiveness of the willow bark. He obtained some, pulverized it into tiny pieces, and conducted experiments on its properties. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, stone presented his tiding to the British Royal Society. Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. These chemists, Brugnatelli and Fontana, determined that the active chemical that was responsible for the medicinal characteristics in the willow bark was the chemical salicin, which is the active ingredient of today's aspirin. The name "aspirin" is the trade name of the drug based on the chemical salicin, properly known as acetylsalicylic acid.The trade name "aspirin" was invented for the drug in the 1890s by the Bayer Drug Company in Germany. The fist bottles of aspirin actually went on sale to the publicjust prior to the turn of the century, in 1899.

Durable Ceramic Beauty
Inside an art and craft workshop, a young woman sits in front of a pottery wheel. The machine contains a large lump of clay which she molds into the shape of an elaborate bowl. Later, when she is satisfied with its appearance, it will be baked in an oven until it solidifies. Then she adds decorative paints to add some style. In the end, this ceramic pot will be both a handy utility for eating as well as a work of art. Humans have been working with ceramics for about 30,000 years, making it one of the oldest industries on the planet. In ancient times, ceramics enabled humans to make containers to store food and drinks, as well as bricks for buildings, but as time went on, people found other uses for this prehistoric technology. Techniques were added to give these products more eye-catching designs. Objects were often coated with glaze, so they would be smoother and more pleasant to touch. This helped to transform these practical items into works of art. People would pay large amounts of money for pieces of ceramic art and use them to decorate their homes. In modern times, architects and inventors discovered that ceramic offered the perfect balance between beauty and durability, and started using it in their products as well. Ceramics have found a home in the world of automobiles as they are used to produce several products. They are often used to make brake discs, engines, and other parts because ceramics are able to withstand extremely hot temperatures. Ceramics also play a part in the world of medicine, as their flexibility and strength are perfect for creating sturdy dental implants. Other doctors are using them to replace damaged bones because they are able to bond with tissues in the body without causing adverse reactions. In many kitchens today, you will also find ceramic knives. Once they are produced, the hard edges of these blades rarely need to be sharpened. Unlike metal knives, they won’t rust when exposed to difficult conditions. Ceramics also help to make it possible for humans to travel into space. Space shuttles are designed with ceramic tiles because they are one of the few materials that can stand the extreme heat when reentering the Earth’s atmosphere, plus they don’t wear out easily. With so many useful applications, it is hard to deny that ceramic technology is out of this world.

Don’t Handle with Care
People always go shopping for the latest and greatest gadgets. Speed, performance, and the latest functions are always key factors before making a purchase. Yet the most important factor of all, which often isn’t considered, is a product’s durability. After all, if a product breaks easily and can’t be repaired, the buyer will have wasted their investment. In other cases, weakly-designed product can cost someone their life. Thankfully, today’s inventors and engineers coming up with some incredible ways to ensure that many products can survive the most difficult situations. One area where durability is absolutely essential is in designing weaponry. In the industry, lapses in quality can lead to death. Designers of military vehicles have recently made great strides in creating some extra tough bulletproof vehicles. Researchers were inspired by the advances made with a similar technology, bulletproof vests. This equipment, which keeps police officers and soldiers protected from gunfire, has been continually upgraded as time has gone on. In order to get tougher, these vests have got lighter, so officers and soldiers can move more freely while working. Beautiful screens, a fast computer processor, and the latest software are probably the biggest concerns for most people shopping for new smartphones. Yet, since most mobiles will be subject to their fair share of bumps and bruises during their life cycle, durability should also be a major concern. A major breakthrough in recent years was the invention of Gorilla Glass. This technology not only prevents devices from breaking when dropped on hard surfaces, but it also makes them scratch-resistant as well. Gorilla Glass screens are given molten alkaline salt baths that produce a hard, compressed layer at the surface. Before a screen can crack, it will have to penetrate this rugged surface, which takes a large degree of force. Recently, another new technique called electrospinning was developed that could make future products even tougher to break. The process involves applying high voltage to a polymer to create a strand of nanofiber. Products designed with the material will be able to absorb more energy without breaking. Researchers are aiming to lighten up aircraft and potentially decrease the damage planes suffer in crashes. Hopefully, these advances are just the beginning. Although science has come a long way in helping manufacturers to create more durable products, the next century should surely bring some even more incredible improvements.

The Wonders of Wetlands
If you’re searching for scenic places or areas, visiting wetlands probably won’t be high on your list. Wetlands are areas of land that are often saturated with water and they are quite an eyesore. Although they might not look very pretty, they play an important part in keeping the environment clean and suitable for plant and animal life. With the exception of Antarctica, wetlands occur naturally on every continent. There are many different types of wetlands on the Earth, including bogs, swamps, and marshes. Along with rainforests, they are among the most diverse places on the Earth. In addition to naturally-occurring wetlands, humans are creating artificial ones for a number of purposes related to water management. One of the main benefits of wetlands is that they can prevent floods. They do so by storing water temporarily and then slowly releasing it over time. Wetlands operate similarly to a sponge. When it rains heavily and water levels rise, they absorb the excess water. This prevents runoff from entering streams and keeping them from overflowing. Then, when water levels become low in the future, they will release it. In many cases, wetlands offer a much more affordable solutions than dams. However, it’s important to note that wetlands, like dams, don’t eliminate all dangers from flooding. In cases of extremely heavy rainfall, wetlands can fill up and any additional water will start to run off. Wetlands can also play a part in water purification. Agricultural practices, urban runoff, and sewage waste are a major cause of water pollution. Wetlands contain plants and organisms that can reduce this pollution by filtering out unwanted substances such as chemicals, and decomposing matter, as well as sediment. Wetlands have additional benefits for the environment as well. They can help to feed nearby fish populations by releasing vegetative matter to rivers. Also, many amphibians use wetlands as breeding grounds because it provides places for foraging and the shallow water they require for reproduction. Some birds also use wetlands for migration, as they can settle in trees and then raid the wetland’s waters for fish when they’re hungry. Although wetlands may not look pretty, it’s clear that they are capable of doing the dirty work required to keep our planet clean and ensure that the circle of life remains unbroken.

Saving the Rainforests
One of the hottest topics related to the environment is rainforests. Despite always being mentioned in the news, many people don’t know very much about these areas or understand why they are so important. The name “rainforest” actually does a pretty good job of describing what they are – tall forests that receive high amounts of precipitation. In a year, rainforests get between 250 to 450 centimetres of precipitation. There are two types of rainforests: tropical rainforests and temperate rainforests. Tropical rainforests are more plentiful and are located in warmer climates, while temperate rainforests are found in places where the weather is a bit milder. In terms of location, rainforests can be found on every continent with the exception of Antarctica. Although they only cover 6 percent of the Earth, over 50 percent of the Earth’s animal and plant species can be found there. Many biologists estimate that there are possibly millions of additional species present there that have yet to be discovered and classified. Over the years, rainforests have gained the nickname “the world’s pharmacy” because more than 25 percent of natural medicines were found there. Many herbs that are used to make medicines can only be found in rainforests. Rainforests are also home to several tribes that have lived off the land for thousands of years. During this time, they have survived by hunting animals and gathering fruits and vegetables. They also possess tremendous knowledge when it comes to crafting and applying medicines made from herbs and plants. Over time, their unique way of life has declined as they have come in contact with modern civilization. Despite their numerous benefits, rainforests have been disappearing at a rapid speed. As the Earth’s population continues to expand, developers have been cutting down their trees to create new lands for farming or urban projects. This could have unfortunate long-term effects on our planet. If deforestation continues at this rate, it is possible that a quarter of all species on the Earth may become extinct in the next 50 years. As it stands, plenty of damage has already occurred. West Africa has had 90 percent of its rainforests destroyed, while the island nation of Madagascar has eliminated 66 percent of its original rainforests as well. As a result, many charities have sprung up with the goal of purchasing and protecting the remaining rainforests. With their help, hopefully we can stop the destruction of one of the planet’s most vital assets.
