Journalists: Protection of Sources
Being a reporter for a major news publication can be a difficult job. The best journalists often work long hours and have to do a bit of dirty work to uncover scandals that others want to remain secret. In many cases, it is a bit of information provided by an undisclosed source that finally helps to break the story. But do reporters have a legal right to keep their sources a secret? The protection of sources is the idea that journalists have the right to keep their sources of their news stories a secret. Those who support this idea insist that if reported are forced to reveal their sources, it will be much harder for them to do their job. It certainly seems logical that fewer people would come forward with sensitive information if they know that eventually their identity will be revealed to the public. Furthermore, in cases where the source’s information uncovers a ring of corruption or somehow damages the reputation of a rich and powerful person or company, releasing the source’s identity could put their life in danger. For the most part, reporters are rarely required by law to reveal undisclosed sources if it is a minor case of little importance. Yet in some instances, when vital or leaked information is involved, a journalist may be asked to testify in court and reveal how they got their information. In the US, such a situation arose after a mass shooting in Colorado in 2012. One journalist, with information provided by an anonymous source, wrote an article claiming that the suspected killer had sent a diary detailing plans to kill people to his psychiatrist a few days before the murder occurred. The suspect’s lawyer then demanded the reporter should reveal her source because they felt it damaged their defense case. In the end, the judge declined to force the reporter to testify. So are there any cases when reporters should reveal their sources? Many would argue that when the issue is a matter of national security, journalists should be willing to reveal their sources if it can help to save lives. For instance, let’s say a reporter receives a tip from an anonymous source about a terrorist attack. In this scenario, saving innocent lives should be more important than protecting one’s source. In the end, it seems that forcing reporters to reveal their sources should be considered on a case-by-case basis.

Prehistoric mammoths have been preserved in the famous tar pits of Rancho La Brea (Brea is the Spanish word for tar) in what is now the heart of Los Angeles, California. These tar pits have been known for centuries and were formerly mine for their natural asphalt, a black or brown petroleum-like substance. Thousands of tons were extracted before 1875, when it was first noticed that the tar contained fossil remains. Major excavations were undertaken that established the significance of this remarkable site. The tar pits were found to contain the remains of scores of species of animals from the last 30,000 years of the Ice Age. Since then, over 100 tons of fossils, 1.5 million from vertebrates, 2.5 million from invertebrates, have been recovered, often in densely concentrated tangled masses. The creatures found range from insects and birds to giant ground sloths, but a total of 17 proboscideans (animals with a proboscis or long nose) - including mastodons and Columbian mammoths - have been recovered, most of them from Pit 9, the deepest bone-bearing deposit, which was excavated in 1914. Most of the fossils date to between 40,000 and 10,000 years ago. The asphalt at La Brea seeps to the surface, especially in the summer, and forms shallow puddles that would often have been concealed by leaves and dust. Unwary animals would become trapped on these thin sheets of liquid asphalt, which are extremely sticky in warm weather. Stuck, the unfortunate beasts would die of exhaustion and hunger or fall prey to predators that often also became stuck. As the animals decayed, more scavengers would be attracted and caught in their turn. Carnivores greatly outnumber herbivores in the collection: for every large herbivore, there is one saber-tooth cat, a coyote, and four wolves. The fact that some bones are heavily weathered shows that some bodies remained above the surface for weeks or months. Bacteria in the asphalt itself would have consumed some of the tissues of other than bones, and the asphalt itself would dissolve what was left, at the same time impregnating and beautifully preserving the saturated bones, rendering them dark brown and shiny.

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:
Composers today use a wider variety of sounds than ever before, including many that were once considered undesirable noises. Composer Edgard Varese (1883-1965) called thus the “liberation of sound…the right to make music with any and all sounds.” Electronic music, for example – made with the aid of computers, synthesizers, and electronic instruments – may include sounds that in the past would not have been considered musical.
Enviromental sounds, such as thunder, and electronically generated hisses and blips can be recorded, manipulated, and then incorporated into a musical composition. But composers also draw novel sounds from voices and non-electronic instruments. Singers may be asked to scream, laugh, groan, sneeze, or to sing phonetic sounds rather than words. Wind and string players may lap or scrape their instruments. A brass or woodwind player may hum while playing, to produce two pitches at once; a pianist may reach inside the piano to pluck a string and then run a metal blade along it. In the music of the Western world, the greatest expansion and experimentation have involved percussion instruments, which outnumber strings and winds in many recent compositions. Traditional persussion instruments are struck with new types of beaters; and instruments that used to be couriered unconventional in Western music – tom-toms, bongos, slapsticks, maracas – are widely used.
In the search for novel sounds, increased use has been made in Western music of Microtones. Non-Western music typically divides and intervals between two pitches more finely than Western music does, thereby producing a greater number of distinct tones or micro tones, within the same interval. Composers such as Krzysztof Penderecki create sound that borders on electronic noise through tone clusters – closely spaced tones played together and heard as a mass, block, or band of sound. The directional aspect of sound has taken on new importance as well Loudspeakers or groups of instruments may be placed at opposite ends of the stage, in the balcony, or at the back and sides of the auditorium. Because standard music notation makes no provision for many of these innovations, recent music scores may contain graph like diagrams, new note shapes and symbols, and novel ways of arranging notation on the page.

The Greatest Light Show on the Earth
If you are a fan of amazing visual displays, planetariums around the world offer some entertaining laser-light shows that are often accompanied by popular music. Yet if you want to see the world’s greatest light show, you won’t be able to catch it indoors. Instead, you will have to head to one of the Poles. In certain spots, you will be treated to colourful streaks of light dancing across the sky. This incredible display is the aurora borealis, and every year people from all corners of the globe flock to witness its wonders firsthand. The Aurora Borealis, or Northern Lights, got its official name in 1621. The name combines the name of the Roman goddess of the dawn, Aurora, and the Roman god of the north wind, Boreas. In ancient times, the aurora completely baffled people’s minds, as science was far more primitive than it is today. Nevertheless, they created many myths to explain them. The Vikings believed the lights were the reflection of dead maidens. The Scots thought they were supernatural beings battling in heaven. Meanwhile, Eskimos thought that the lights were dead souls, and when the colours changed, it was their attempt to contact living friends and relatives. It was not until 2008 that a team of scientists from ULCA finally concluded with certainty what the true cause of these dancing light is. The process begins when solar winds carry charged particles from the Sun through space and into the Earth’s atmosphere. When these charged particles enter the Earth’s atmosphere, they are magnetically attracted to the Earth’s poles. During their journey to these points, they come in contact with nitrogen and oxygen atoms in the sky. These collisions are what cause the aurora. The heights at which the collisions occur determine the colours of the individual lights. For example, when the solar winds collide with nitrogen at least than 96 kilometres above the Earth’s surface, the lights will be blue. If the same collision occurs above 96 kilometres, however, the light will be purple. Or, if the solar wind particles collide with oxygen, the colours produced will be either red or green. However, merely understanding how the aurora works does not do this phenomena justice. To truly appreciate the full splendor of the aurora, you will have to see this Natural Wonder of the World in person.

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.

Poor Pluto! Once the ninth planet in our solar system, Pluto has now been demoted to the status of a "dwarf planet". It is no longer even part of our solar system, but rather of a separate area called the Kuiper Belt. The decision came about after the International Astronomical Union (IAU) tried to shed some light on Pluto's status. It came up with a new definition for planets that Pluto did not fit. Many in the astronomical disagreed with it, especially since the Earth, Mars, Jupiter and Neptune would not be planets either according to this definition! Only five percent of the astronomical community voted on this issue, and critics say this decision was not based on the community as a whole. In the state of New Mexico, a resolution has been passed that Pluto will always be a planet. This was done in honor of Clyde Tombaugh who discovered Pluto and lived most of his life in New Mexico. Pluto's demotion was also influenced by its size - it's only half the size of our moon! It consists of rock and ice. Pluto has one big moon (Charon) an two smaller ones (Nix and Hydra). Lowell realized that there must be a ninth planet as the gravitational pull of a large body was influencing the orbit of Uranus. He called it "Planet X". He spent his whole life searching for "Planet X" but to no avail. It was until 1930 that it was discovered by Clyde Tombaugh. Now that "Planet X" has finally been discovered, it needed a name. Suggestions poured in from all over the world, but it was an 11 -year-old girl. Venetia Burnet, who came up with the name "Pluto". Venetia was interested in Greek history, and "Pluto", was another name for Hades, god of the Underworld (Hell). As she imagined it to be a cold and dark place, she felt that "Pluto" would be an appropriate name. The Lowe Observatory (where Clyde Tombaugh worked) agreed and Pluto was born! Pluto is so far away from Earth that it is difficult to study. That will change in 2015 when the "New Horizons" spacecraft arrives on Pluto. It was launched on January 19.2006. It carries with it the ashes of Clyde Tombaugh Pluto's discover who died in 1997. It is hoped that the mission will give scientists more information about Pluto. Even though Pluto has lost its place in the sun, it is still important enough for scientists to study!
