Incredible Shrinking Microchips
There is a popular old saying that “bigger is better”. Although this may be true in some regards, the exact opposite often applies in technology. As electronic components get smaller, it allows companies to manufacture tinier devices with more features. Thus began the never-ending quest to create the smallest microchips on the planet. Yet as these vital electronic components get smaller, they are also getting stronger and clever inventors are finding new ways in which to use them to do incredible things. Currently, the biggest limitation microchip producers face when trying to reduce chips’ size is the copper wires that provide electrical current throughout the chip. Although they can be made smaller, this can cause a whole host of problems such as melting and overheating. Thanks to the work of a few scientists from the UK though, this problem may soon be a thing of the past. Their solution is getting rid of the copper wiring altogether and using carbon nanotubes instead. Not only would this allow for smaller sizes but it would also increase the power that microchips can generate. In the end, this would translate into smaller and more powerful devices much to the delight of consumers all over the world. Corporate powerhouse Intel® has announced plans to create a line of tiny, low power chips that can be used in bracelets, smart watches, and other tiny devices. The chips will be called Intel® Quark, and they are being designed primarily to fit in biomedical devices. A key selling point to biomedical technology is that the devices have to be nonintrusive because people don’t want to carry around heavy equipment to monitor their health. If they can do this, Intel® will likely find several tablet and smartphone manufacturers who are willing to corporate Quark microchips into their devices. In a somewhat unusual project, researchers are working on a special microchip that will serve as miniature human organs in experiments. These “organ” chips could be used to test different medicines and study diseases. If realized, the technology could put an end to the use of lab mice and other animals for testing. Everyone from the largest pharmaceutical companies to the US military has shown interest in the project. Currently, the research team in charge of the project believes that within five years the organ chips will be used in practical research. It goes to show that thinking small often produces the biggest results.

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.

Sometimes forest fires have caused serious damage to both private and public property. They destroy many houses and cause deaths, particularly when they have reached villages which are close to the forests. It is more dangerous if a destructive fire burns away plants and trees that prevent erosion. If heavy rains occur after such a fire, landslides, ash flows, and flash floods can occur. This can result in property damage in the immediate fire area, and can affect the water quality of streams, rivers and lakes. Wind sometimes makes contributions to forest fires. In southern California, under the influence of Santa Ana winds, fires could move at tremendous speeds, up to 40 miles (60 km) in a single day, consuming up to 1,000 acres (4 km2) per hour.

The Great Energy Debate
Modern civilization is heavily dependent on energy. Without reliable power sources, we couldn’t operate machines, use transportation, communicate via Internet, or do many other things. Although everyone recognizes the importance of energy, deciding what kind of energy the world should use in the future is not a simple task. The two leading candidates for this role are green energy and nuclear energy. Currently, most of the energy we use is derived from fossil fuels. Although this energy source has got us this far, there are several problems with it. For starters, it is a finite resource which is quickly running out. Some analysts have even estimated that the Earth could run out of coal and oil within the next 50 years. Burning fossil fuels also creates large amount of pollution, which is harmful to the environment. Although fossil fuels still provide the majority of our power, governments are seeking better energy sources to use going forward. Green energy is one option that is becoming increasingly attractive. It includes technologies such as solar, wind, and hydro power. These are seen as clean sources of energy because they cause very little pollution. In addition, they are completely renewable, so there is no danger that it will run out. The major disadvantage with green energy sources is that they are not cheap. The other alternative is nuclear power. Like green energy, it is also a renewable source of power that will not run out, and it also doesn’t produce air pollution. In addition, nuclear power is more reliable than green energy, as it doesn’t depend on sunshine, rain, or wind to operate. The major issues with nuclear power are safety concerns and nuclear waste. Nuclear power plants create a considerable amount of nuclear waste which is extremely hazardous to people’s health. If they happen to have a meltdown, this could destroy the surrounding area for years to come. The recent nuclear disaster in Fukushima, Japan brought this reality into the spotlight once again. In response, Germany announced it would close down eight of its nuclear plants immediately, and close the rest by 2022. Meanwhile, other nations refuse to give up on nuclear power, stating that these disasters are rare. The debate of whether to use green or nuclear power will likely continue for some time. In the end, it is quite possible that both energy sources will be used to fuel our planet.

The ability to conduct electricity is one of the key properties of a metal. Other solid material such as silicon can conduct electricity but only effectively at certain temperatures. Also, some substances such as salt (sodium chloride) can conduct when molten or when dissolved in water. The ability of metals to conduct electricity is due to how their atoms bond together. In order to bond together the metal atoms lose at least one of their outermost electrons. This leaves the metal atoms with a positive charge and they are now strictly ions. The lost electrons are free to move in what are known as a sea of electrons. Since the electrons are negatively charged they attract the ions and this is what keeps the structure together.

An electric current is a flow of charge and since the electrons in the sea of electrons are free to move they can be made to flow in one direction when a source of electrical energy such as a battery is connected to the metal. Hence we have an electric current flowing through the wire, and this is what makes metals such good conductors of electricity. The only other common solid conducting material that pencil users are likely to encounter is graphite (what the 'lead' of a pencil is made from). Graphite is a form of carbon and again the carbon atoms bond in such a way that there is a sea of electrons that can be made to flow as an electric current. Likewise, if we have an ionic substance like salt we can make the electrically charged ions flow to create a current but only when those ions are free to move, either when the substance is a liquid or dissolved in water. In its solid state an ionic substance like salt cannot conduct electricity as its charged ions cannot flow.

Electrical insulators are substances that cannot conduct electricity well either, because they contain no charged particles or any charged particles they might contain do not flow easily. Water itself is a poor conductor or electricity as it does not contain a significant amount of fully charged particles (the ends of a water molecule are partly charged but overall the molecule is neutral). However, most water we encounter does contain dissolved charged particles, so it will be more conductive than pure water. Many of the problems that occur when touching electrical devices with wet hands result from the ever-present salt that is left on our skin through perspiration and it dissolves in the water to make it more conductive.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Most people can remember a phone number for up to trirty seconds. When this short amount of time elapses, however, the numbers are eerased from the memory. How did the information get there in the first place? Information that makes its way to the short term memory (STM) does so via the sensory storage area. The brain has a filter which only allows atimuli that is of immediate interest to pass on to the STM, also known as the working memory.
There is much debate about the capacity an duration of the short term memory. The most accepted theory comes from George A.Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or nam rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.
When making a conscious effort to memorize something, such as information for an exam, many people engage in “rote rehearsal”. By repeating something over and over again, one is able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, people often attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before a person has the opportunity to make a phone call, he will likely forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice “elaborate rehearsal”. This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.
Encoding information semantically also makes it more retrievable. Retrieving information can be done by rocognition or recall. Humans can easily recall memories that are stored in the long term memory and used often; however, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures), the more likely a memory can be retrieved. This is why multiple choise tests are often used for subjects that require a lot of memorization.
