1-In 1945, crocodiles killed 980 Japanese soldiers (of 1,000 in total) who entered a mangrove swamp to escape the British navy 2-Researchers at the University of Barcelona carried out a study, which showed that rats couldn’t tell the difference between Japanese spoken backwards and Dutch spoken backwards. Maybe the rats just didn’t care… 3-Japanese scientists have bred completely see-through frogs so that they can investigate their internal organs without having to kill and dissect them. 4-In 1982, Japanese scientists found a 10,000-year-old magnolia seed in a storage pit. They managed to grow it into a tree! 6-Mount Fuji, the volcano that towers over the Japanese capital Tokyo, last erupted in 1707.The earthquakes and tsunami that followed killed 30,000 people and the rice fields were left barren for 100 years. 7-A volcanic eruption destroyed the Roman city of Pompeii in AD79.The energy the eruption released was 100,000 times more powerful than that of the atomic bomb dropped on Hiros...
Atoms are tiny particles which build together to make every substance. An atom is the tiniest bit of any pure substance or chemical element. You could fit two billion atoms on the full stop after this sentence. The number of atoms in the Universe is about 10 followed by 80 zeros. Atoms are mostly empty space dotted with a few even tinier particles called subatomic particles. In the centre of each atom is a dense core, or nucleus, made from two kinds of particle: protons and neutrons. Protons have a positive electrical charge, and neutrons none. Both protons and neutrons are made from different combinations of quarks (see quarks). If an atom were the size of a sports arena, its nucleus would be just the size of a pea. Around the nucleus whizz even tinier, negatively-charged particles called electrons (see electrons). Atoms can be split but they are usually held together by three forces: the electrical attraction between positive protons and...
