Nickel is one of today's most popular metals, and chances are that, as we speak, you have at least a few nickel coins in your pocket.

Since there is not water on the Moon and carrying anything there from the Earth would cost loads of money, it is obviously cheaper to use directly the Moon's resources in order to make water-free concrete.

Mercury is the smallest, most mysterious and closest planet to the Sun. In fact this so called 'mystery' is associated to Mercury also being the least studied planet in the solar system, which may seem kind of strange given the fact that it is relatively close to Earth as compared to the other planets beyon... |

There are 112 active or inactive volcanoes in Costa Rica, but Poas, 2,700 m (9,000 ft) tall, is extremely unusual. It is not the most active (this being Arenal, 1,500 m/5,000 ft tall) nor the tallest (this being Irazu, 3,400 m/11,330 ft tall), but it has two craters: an active one, while the other holds a lake surrou... |

Onions can make you cry (or laugh, if you watch "Cry Onion", the 1975 Western movie with Franco Nero). Just like garlic, their relative, onions originated in central Asia and they were first grown in Iran and West Pakistan over 5000 years ago. No wonder, as onions are rich in sugars (there is a higher sugar amount in... |
