WHILE READING

GAP FILL: Put the words into the gaps in the text.

Scientists in the USA say they are a __________ closer to developing materials that could make people invisible. Researchers at the University of California have found a way to __________ humans and objects using special materials that __________ light around things. The findings, led by Professor Xiang Zhang, were published in the __________ ‘Nature’ and ‘Science’. Zhang works at the Nanoscale Science and Engineering Centre at the university. His team developed a __________ of artificial “meta-materials” on a microscopic __________ that is measured in billionths of a metre. The researchers said the special “fishnet structure” of the nano-__________ objects do not absorb or reflect light, which makes them seem invisible. They __________ the light to “water flowing around a rock".     set redirect compared step scale journals sized cloak
The new discovery is a __________ step forward from earlier technology that only allowed the concealing of two-dimensional __________. In the future, scientists could make “invisibility clothing” to __________ people and large objects. However, scientists are still a long __________ from designing and manufacturing invisibility cloaks. The U.S. military is extremely interested in developing this __________ to bring the technology to the __________. 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 __________ at living cells and even tinier objects. This means scientists could look at how viruses are formed and how they __________.   hide battlefield idea objects grow huge closely way
