Flying Drones into Danger Zones
A plane is sent deep into the enemy territory with a deadly mission. It is assigned to eliminate several key targets with a precision bombing campaign. This mission won’t be easy, however, as to be successful, the plane will have to avoid enemy rockets and tank fire. There will be no risk to the life of the “pilot” of the plane because he will not be able to aboard the vessel. Instead, he will be thousands of miles away inside a control tower, as he is operating a drone. Drones, which are also called UVAs or unmanned aerial vehicles, marked a major step forward in technology. Inventors have been working on them since the early 1900s. Although some devices were designed back then, they weren’t able to do much more than a standard model airplane. In fact, it was not until a US plane was shot down in 1959 during the Cold War that the US military really got serious about drones. The aim was to save pilots’ lives while flying over hazardous territories. Drones usually fall into two categories. The first type of drones relies on human control from a remote location. The second type of drones is pre­programmed with computer instructions, and it then completes its mission operating autonomously. In addition to protecting pilots’ lives, drones also have several other advantages. They can stay in the air for longer periods of time because there is no concern for eating, sleeping, or rest breaks that pilots typically require. Drones can also be produced cheaper since manufacturers don’t need to value safety precautions as they would for aircraft flown by humans. Despite their usefulness, military drones have been the cause of great criticism over the past decade. There have been cases of British and American drones missing their targets and killing innocent civilians instead. The Brookings Institution released a statistic that for every military leader who is killed by a drone strike, ten civilians die. Some suggest that if human pilots were flying these planes, they wouldn’t have made these errors. Drones don’t always have targets that they must eliminate. The military also employs special surveillance drones that use long-range cameras to gather information about buildings, enemy soldier formations, and other vital information from the ground. In the end, whether people are for or against the use of drones, it appears that they are certain here to stay.

The Advancing Development of Artificial Limbs
It wasn’t very long ago that losing a limb automatically meant a drastic drop in the quality of a person’s life. Thanks to the wonders of modern science, people now are recovering from all sorts of horrendous injuries that let them disabled. The reason they are able to do so is remarkable advances made in the field of artificial limbs. Doctors have been creating prosthetic limbs for their patients dating back to ancient Greece. For most of history, however, these replacements were mainly for cosmetic purposes. Pirates, knights, loot soldiers that lost their limbs in battle would get them, so they wouldn’t lose face when returning to society. It wasn’t until the mid-19th century that doctors were able to perform surgeries to reliably attach limbs to people’s bodies and amputate limbs without causing serious infection. Modern artificial limbs represent a tremendous leap forward in terms of form and function. Today’s limbs are far more durable and can withstand a lot more wear and tear. An amazing example of how far artificial limbs have progressed is the Flex-Foot Cheetah. Made from carbon fiber, it is able to store energy as the person moves, which enables the wearer to run and jump. The technology is so good that approximately 90 percent of all Special Olympic amputees use them in competition. Meanwhile, the Bebionic3 has emerged as the most advanced prosthetic arm available. It has been nicknamed “The Terminator” because it is similar to Arnold Schwarzenegger’s mechanical limbs in the famous blockbuster film. The Bebionic3 can perform a multitude of tasks including writing, tying a shoelace, lifting heavy objects, and even pouring a beer. Wearers simply push a button on the base of the arm and the Bebionic3 will work its magic. In September 2013, scientists took another giant leap forward when they successfully fitted a patient with an artificial leg that can be controlled by thought. Two of the patient’s nerves were attached to his hamstring muscle. These nerves then interact with sensors inside the artificial leg. Sensors will then transmit these messages to a computer which will follow through on his instructions. Therefore, if the patient wants to stretch out his leg, the computer will understand this command and send a message to the limb and instruct it to do so. If artificial limb technology keeps advancing like this, losing a limb may not be such a big deal.

The Particle that Started the Big Bang
In 2013, the Nobel Prize for Physics was awarded to Francois Englert and Peter W. Higgs for their discovery of a particle that is vital to our understanding of the universe. Although its official name is the Higgs boson, many refer to it as the God particle, because it’s considered to be the building block of the universe. Many believe that the Higgs boson may be the cause for the Big Bang explosion which led to the creation of the universe. In the 1960s, Higgs came up with the concept that particles had no mass when the universe started. In a split-second, however, it came into contact with something that gave it mass. This, Higgs theorized, was the Higgs boson. Many scientists initially laughed at the idea, but in the upcoming years, Higgs along with Englert and several of their peers continued to work on these concepts. Their ideas would eventually help lead the way to the discovery of the Higgs boson decades later. The search for the Higgs boson certainly didn’t come up cheap, as it cost nearly $10 billion to build the machinery necessary to perform the tests to find it. Yet nearly every physicist would agree that it was worth it, as the Higgs boson has already been labeled as one of the most important discoveries in particle physics. The finding is also a huge boost for physics in general because it proves that the Standard Model of Physics which researchers have been using for years is correct. The Higgs was the last remaining question mark as all of the other particles and elements had been found. Still, many ordinary people may question how such a discovery affects their lives at all. Although quantum mechanics may seem weird, it has actually led to several important technological breakthroughs over the past century. These findings have led to laser and X-ray technologies that work in the real world. There is still much to be learned with further observation of the Higgs boson in action. Scientists hope to learn more about dark matter, a strange substance that constitutes 25 percent of the mass of the universe. The research could also lead to some other technologies as well.
