Here are the sentences with the appropriate words filled in:

1. But living in a fortress without windows has its downsides too. One challenge for the termite mound is getting enough fresh air into the intricate system of tunnels they inhabit. But a new study published in this month's Proceedings of the National Academy of Sciences has recorded what actually happens inside the termite mound and revealed that the termites ventilate themselves thanks solely to their ingenious design.

2. A bullet train emerging from a tunnel generates a thunderclap due to the air pressure which builds up in front of the nose. In the 1990s, a Japanese engineer Eiji Nakatsu noticed that kingfishers could dive into the water with barely a splash. His design for the Shinkansen bullet train, based on the kingfisher beak, not only reduced the noise of the train but was also more aerodynamic, using less power and enabling higher speeds.

3. The brilliant color of some butterfly wings comes from an assembly of tiny plates in a specific pattern that reflects light of a certain wavelength. Researchers are looking to develop similar color displays for e-readers; they would work by reflecting light, not transmitting it from behind the screen, like LCD screens do.

4. The effects of static electricity were first recorded by a Greek philosopher Thales of Miletus who lived between 624 and 546 BC. He is said to have experimented with amber, which the Greeks referred to as elektron, and cat fur to create an electrical discharge as well as magnetism.

So to summarize:

1. termite mound
2. kingfishers
3. butterfly wings
4. amber
