Mobile phones contain a metal extracted from an ore called columbite-tantalite (or Coltan). Vast areas of African gorilla habitats are destroyed every year as we buy more and more mobile phones.

This is the Northrop Grumman B-2 Spirit (stealth bomber). This machine is capable of pin-point strikes on most any hardened target available such as underground bunkers. Needless to say, it is also capable of delivering nuclear weapons.

This stealthy aircraft was designed in a way that enemies could not anticipate its arrival, but its 22,600 Kg bomb load and a multitude of nuclear missiles would ensure they'd know when it had arrived. Named the B-2 Spirit, its advantage in battle is derived from its designation spirit; it operates like a ghost.

This is a white-blooded ice fish, or "crocodile fish" (Chaenocephalus aceratus). They lack both red blood cells and hemoglobin, and so have white blood. They have translucent bodies, and absorb oxygen directly from the water around them.

Are humans really at the top? Yes. We are the top of the food chain (unless we are eaten by a shark!), but is it always beneficial to be at the top of the food chain?

Usually food chemicals that we eat are used by our bodies and any waste is exhaled, defecated and urinated out of us. However, some chemicals such as heavy metals like lead and mercury can't be expelled from plants and animals so they build up in the plant and animal bodies. This is called biomagnification (biological magnification) because the amounts can accumulate more and more in animals further along the food chain till they reach a toxic level.


In human-made environments, radio-active chemicals such as uranium are a problem because the time they take to break down (half-l ...

Not much of a believer in dwarf planets, but here's a cool schematic of some.


In 2006 the organization responsible for classifying celestial bodies, the International Astronomical Union, decided that a new class of objects was needed. The solar system's erratic ninth planet, Pluto, was assigned to the new “dwarf planet” category along with four other bodies, all tinier than Earth’s moon. Some astronomers expect there may be as many as 50 dwarf planets in the solar system.

Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km). Discovered in 2003, Eris orbits at an average distance of 68 AU (that is, 68 times the Earth’s distance from the sun) and takes 561.4 Earth years to circle the sun. E ...
