Cleaning the World’s Oceans
Imagine taking a romantic walk on the beach with your loved one. As the sun begins to set, you hope to treasure this moment forever. Just then, your bare feet stumble over something and you hear a crack. You have just stepped upon a plastic soda bottle and some junk that the tide has washed ashore. Scenarios like this are happening more frequently due to an access amount of sea rubbish, and the worst of it is found far from land. The increasing accumulation of garbage in oceans is due to a number of factors. Studies suggest that 80 percent of all debris originated on land. The majority of this waste is in the form of plastics. This is particularly troublesome because plastic does not degrade at the same rate that other materials do. Therefore, these articles will remain there for quite some time. Some of the pollution is caused accidentally. For example, about 10,000 product-filled containers are lost at sea every year by freight ships. In other cases, the littering is more deliberate, such as the moment when people toss things into the water from boats or land. One of the most startling discoveries of recent years was an area which is now dubbed the Great Pacific Garbage Patch. It is a large collection of marine debris that collected in the North Pacific Ocean. Although the patch is quite massive, it is undetectable from satellites in space because most of the rubbish is underneath the surface. It was discovered in 1997 by a man who happened to spot it while returning home from a sailing race. The patch formed as a result of rubbish being carried by currents and then getting trapped in the area. Thankfully, the problem of ocean garbage is not being ignored. Organizations like the National Oceanic and Atmospheric Association (NOAA) are taking action. It has funded 76 projects that take an aggressive approach to eliminating sea rubbish. Since 2006, it has removed 3,814 metric tons of marine debris from oceans. Methods of rubbish removal include using machines that skim the surface of ocean waters and remove any drifting materials found. In addition, special traps are set by the mouths of rivers to snatch rubbish before it reaches the sea. If everyone does their part, sea rubbish seems like an issue that can be resolved.

Hunting Down the Truth about Killer Whales
Hearing that killer whales are in the area is sure to strike fear in the heart of anyone at sea. The thought of coming across a creature with a menacing name like that is a surefire sign you are on a path to destruction. As it turns out, killer whales, orcas, are actually highly sophisticated creatures that are usually harmless to humans. The title “killer whale” may actually be a mistranslation of the Spanish term “ballena asesina”, which means assassin whale. Orcas were nicknamed this due to their well-coordinated attacks on marine life, not for the danger they pose to humans. At nearly five to seven metres in length and a weight of over six tons, orcas are one of the largest creatures on the Earth. There are about 50,000 orcas worldwide that are spread out in several oceans. Orcas are classified as an Apex predator, which means no other creature hunt them for food. Scientists believe that there are between three to five different types of orca and they are all quite distinctive. The most frequently seen of these are Residents. They live in close-knit family units called pods, which can contain over 50 members, and their diet consists mainly of fish. Transient whales, however, prefer to travel in smaller groups of two to six whales. Meanwhile, Offshore whales were only recently discovered in 1988. They prefer to swim farther away from land than the others and several pods may come together to form groups as large as 200 whales. Although these orca groups may seem similar to the naked eye, they are extremely different in many ways, and scientists believe they haven’t interbred in thousands of years. Researchers also acknowledge that their knowledge of orcas is limited, and even more groups may exist. Male orcas have an average lifespan of about 30 years, while the average age for females is 50. However, there have been cases of females living up to 90 years. Yet when kept in captivity at marine entertainment parks, their life expectancies drop dramatically. In fact, it seems that the biggest threat to orcas these days is humans. Between the practices of hunting orcas, polluting their environments, and capturing them for entertainment purposes, we are making it very difficult for them to survive. Perhaps the killer whales aren’t the real killer after all.

Thanks to our modern lifestyle, with more and more time spent sitting down in front of computers than ever before, the number of overweight people is at a new high. As people frantically search for a solution to this problem, they often try some of the popular fad diets being offered. Many people see fad diets as innocuous ways of losing weight, and they are grateful to have them. Unfortunately, not only don't fad diets usually do the trick, they can actually be dangerous for your health. Although permanent weight loss is the goal, fewareabletoachieveit. Expertsestimate that 95 percent of dieters return to their starting weight, or even add weight. While the reckless use of fad diets can bring some initial results, long-term results are very rare. Nonetheless, people who are fed up with the difficulties of changing their eating habits often turn to fad diets. Rather than being moderate, fad diets involve extreme dietary changes. They advise eating only one type of food, or they prohibit other types of foods entirely. This results in a situation where a person's body doesn't get all the vitamins and other things that it needs to stay healthy. One popular fad diet recommends eating lots of meat and animal products, while nearly eliminating carbohydrates. A scientific study from Britain found that this diet is very high in fat. According to the study, the increase of damaging fats in the blood can lead to heart disease and, in extreme cases, kidney failure. Furthermore, diets that are too low in carbohydrates can cause the body to use its own muscle for energy. The less muscle you have, the less food you use up, and the result is slower weight loss. Veteran dieters may well ask at this point, "What is the ideal diet?" Well, to some extent, it depends on the individual. A United States government agency has determined that to change your eating habits requires changing your psychology of eating, and everyone has a different psychology. That being said, the British study quoted above recommends a diet that is high in carbohydrates and high in fiber, with portions of fatty foods kept low. According to the study, such a diet is the best for people who want to stay healthy, lose weight, and keep that weight off. And, any dieting program is best undertaken with a doctor's supervision.

The Invention of the Periodic Table
If you are looking to gain a better understanding of the world around you, chemistry is the perfect subject to study. It is an examination of matter, its properties, and its interactions with everything around it. Where physics often deals with concepts and theories that are difficult to test and observe, chemistry principles can easily be applied to medicine, cooking, and several other areas. At the heart of all these discoveries is one vital chart that organizes elements based on their atomic number and chemical properties: the periodic table. Although the first periodic table was published in 1869, it was a work in progress for hundreds, if not thousands of years. Since ancient times, people have been fascinated with elements such as gold, tin, and copper in their natural forms. They were mined and used to make jewellery, weapons, coins, and many other things. Over time, people became more curious about these metals and how they were composed. In ancient Greece, Aristotle and other philosophers claimed things were made from the elements of earth, water, fire, and air. For years, this theory was accepted. Then people began to reevaluate this concept during the Age of Enlightenment. In 1661, Irish scientist Robert Boyle defined an element as something that “cannot be broken down into a simpler substance by a chemical reaction”. Over a century later, French chemist Antoine-Laurent Lavoisier would publish the first modern textbook on chemistry. In it, he listed several substances which he believed should be classified as elements into two categories: metals, and non-metals. Although his work wasn’t completely accurate, it represented a major step forward at the time. Over the next century, scientists started to classify the elements into different groups depending on their properties and atomic weights. However, it is Russian chemist Dmitri Mendeleev who is usually credited as the first person to make a periodic table. Although other scientists had submitted tables, they were eventually rejected by the scientific community for a lack of detail. Mendeleev arranged all of the elements according to their atomic mass. He was even smart enough to leave empty spaces for elements which hadn’t been discovered at the time. Although Mendeleev’s periodic table wasn’t perfect, it set the format which is similar to the one used today.

Are Human Beings Getting Smarter?
Do you think you are smarter than your parents or grandparents? According to James Flynn, a professor at a New Zealand university, you might be. Over the course of the last century, IQ test scores of people in some countries have got increasingly better - on average, three points better for every decade that has passed. This trend of improving scores is known as “the Flynn effect,” and scientists want to know what is behind it. IQ tests and other similar tests are designed to measure general intelligence rather than knowledge. Flynn knew that intelligence is partly inherited from our parents and partly the result of our environment and experiences, but the improvement in test scores was happening too quickly to be explained by heredity. So what happened in the 20th century that led to higher test scores? Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general. Because we take so many tests, we learn test-taking techniques that help us perform better. Others have pointed to better nutrition, which results in babies being born larger, healthier, and with more brain development than in the past. Another possible explanation is a change in educational styles - children are encouraged to discover things for themselves rather than just memorizing information. This could prepare people to do the kind of problem-solving that intelligence tests require. Flynn himself suggested that learning new technologies may have improved people’s problem-solving skills. This may be true for the first decade of his tests, when IQ scores in many countries increased. However, in recent years, IQ test scores in some countries have begun to decline. Data from Norway, the Netherlands, Australia, and Great Britain have shown that as these countries become more and more modern, IQ scores have begun to drop. While scientists aren’t sure what is causing this decline, they think technology is dramatically changing the way that we learn and get information. For example, people are now able to access all kinds of information easily using online resources like Google or Wikipedia. The danger is when they start to rely too much on these sources of information, and not do any thinking for themselves. Lifestyle changes that come with modem technology may also have a negative effect on intelligence, such as video games and television making people less social.  So while the world may have got smarter over the 20th century, improving technology and changing lifestyles may soon reverse that trend.

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.
