I. Read the text

Travellers at two US airports will soon be searched by new high-tech scanners. International airports in Los Angeles and New York have installed digital body scanners that can ‘see through’ clothing. The new machines will mainly search for weapons and explosives. They use the very latest technology that is called millimeter wave imaging. Radio waves create a 3-D image of someone’s body to see if they are concealing anything dangerous. Government officials say the new equipment will make air travel safer. A spokesperson said: “Imaging devices are not a new security tool, but they are a new security tool for airports.” There are plans to install the devices in another 30 airports across the country. An official promised that passengers will prefer the scanner to a security guard patting their body.

The new technology has raised questions by privacy groups, who believe the scanning process is too detailed. They say the device can see too much of the naked body. A civil liberties spokesman warned: “We need to make sure there are good safeguards. The temptation is great not to follow procedures when a celebrity or someone well-known is involved.” One female passenger at LA airport suggested that only female operators should be allowed to scan female passengers. She said she was highly embarrassed to see a male official looking at the digital image of her body. She was also worried the scanned images could end up on the Internet. It seems it’s only a matter of time, however, before the machines replace metal detectors.

I. Read the text

Scientists in the USA say they are a step closer to developingmaterials that could make people invisible. Researchers at the University of California have found a way to cloak humans and objects using special materials that redirect light around things. The results of the research, led by Professor Xiang Zhang, were published in the journals ‘Nature’ and ‘Science’. Zhang works at the Nanoscale Science and Engineering Centre at the university. His team developed a set of artificial “meta-materials” on a microscopic scale that is measured in billionths of a metre. The researchers said the special “fishnet structure” of the nano-sized objects do not absorb or reflect light, which makes them seem invisible. They compared the light to “water flowing around a rock".

The new discovery is a huge step forward from earlier technology that only allowed the concealing of two-dimensional objects. In the future, scientists could make “invisibility clothing” to hide people and large objects.

However, scientists are still a long way from designing and manufacturing invisibility cloaks. The U.S. military is extremely interested in developing this idea to bring the technology to the battlefield. The U.S. Army Research Office funded part of Dr. Zhang’s research. The technology could also lead to more powerful microscopes that are able to look more closely at living cells and even tinier objects. This means scientists could look at how viruses are formed and how they grow.

A leading US scientist has predicted that computers will be as intelligent as humans by 2029. Futurologist Dr Ray Kurzweil told the American Association for the Advancement of Science that in the near future, machine intelligence will overtake the power of the human brain. He said that within two decades computers will be able to think quicker than humans. Dr Kurzweil painted a picture of us having tiny robots called nanobots implanted in our brain to boost our intelligence and health. He told reporters that these microscopic nanobots would work with our brains to make us think faster and give us more powerful memories. Kurzweil explained that we are already “a human machine civilization” and that the upcoming technology “will be a further extension of that."

Dr Kurzweil was one of 18 top intellectuals asked by the US National Academy of Engineering to identify our greatest technological challenges. Other experts included Google founder Larry Page and the human genome pioneer Dr Craig Venter. Kurzweil has a very impressive background in science and innovation. He was an innovator in various fields of computing, including the technology behind CDs. He also pioneered automatic speech recognition by machines. He predicts the pace of new inventions will increase greatly from now, saying: "…the next half century will see 32 times more technical progress than the past half century." This means scenes from science fiction movies, like The Terminator and I Robot, will become a part of our everyday lives.
