The Damselfly (suborder Zygoptera) is an insect in the order Odonata. They are similar to a dragonfly, but the adults can be differentiated by the fact their wings are held along the body when at rest. They are also usually smaller, and weaker fliers than dragonflies, and the eyes are separated. Photo credit: Fir0002 |

Although used occasionally in later experimental devices, this nuclear weapon design was used only once as a weapon, in Little Boy, because of the extreme danger of a misfire. A simple crash could drive the "bullet" into the "target" and release lethal radiation doses or even a full nuclear detonation. Photo credit: Fastfission |

A mackerel sky is an indicator of moisture and instability at high levels. If the lower atmosphere is stable and no moist air moves in, the weather will most likely remain dry. However, moisture at lower levels combined with temperature instability can lead to spectacular thunderstorms should the rising moist air reach this layer. In weather lore, a mackerel sky portends changeable weather. Photo credit: Denni Windrim |

A plant's leaves are the primary sites for photosynthesis. The green colour is from chlorophyll, a pigment that absorbs the energy from sunlight falling on the leaf. The veins are the vascular tissue of the leaf, moving water into the leaf and the sap produced by photosynthesis back out. Photo credit: PDPhoto.org |
