Ever seen a black flamingo?
|
view preview
On the Mediterranean island of Cyprus, you might be lucky to find a black flamingo. Normal flamingoes are born white and grey, and turn their iconic shade of pinky orange around the age of two, as a result of the high carotenoid content of the algae and crustaceans that they eat. Experts believe that this individual (and potentially the other bird spotted in Israel) has a genetic condition that causes it to overproduce melanin, changing its feathers to black.

Humans and Earth - the battle
|
view preview
When you turn on your TV, it is the definition of ironic to watch the news channels for information about planet mass destruction. Whilst when you step outside your door, it is quite alarming and obvious that our earth is suffering. When every person around you, from toddlers to elderly, own some for of technology, with no means of recycling old items. When students, each with their own copies of pages. When potable water has not yet reached the most needy of nations. When human greed is apparent with every innovative idea claiming to "revolutionize "a domain brought up to make a quick buck. Drilling, mining, industrialization, politics, scavenging for resources, suffocating our environment... This may all seem negative, but coming from a ...

One hairy situation
|
view preview
The hairy frogfish ( Antennarius striatus) is a marine fish with spines resembling strands of hair - and it can change color. This small fish grows up to 22 cm (8.7 in) long, and has a rounded, extensible body. Its large mouth is forwardly extensible, allowing it to swallow prey as large as itself! The coloring of its body is extremely variable because individual fish tend to match their living environments. Frogfishes have the capacity to change coloration and pigment pattern, taking only a few weeks to adapt. The dominant coloration varies from yellow to brownish-orange, passing through a range of shades, but it can also be green, gray, brown, almost white, or even completely black without any pattern. Body and fins can be marked with roug ...

"Give orange me give eat orange me eat orange give me eat orange give me you."
|
view preview
That's the longest string of words that Nim Chimpsky, a chimpanzee who scientists raised as a human and taught sign language in the 1970s, ever signed. He was the subject of Project Nim, an experiment conducted by cognitive scientists at Columbia University to investigate whether chimps can learn language. After years of exposing Nim to all things human, the researchers concluded that although he did learn to express demands - the desire for an orange, for instance - and knew 125 words, he couldn't fully grasp language, at least as they defined it. Language requires not just vocabulary but also syntax, they argued. "Give orange me," for example, means something different than "give me orange." From a very young age, humans understand that; w ...

How does our vision compare to some animals?
|
view preview
Do animals see the same way we do? Do some animals have better vision than humans? The senses of animals have evolved to give members of the species an optimum chance for survival. Here are a few examples: Some animals, such as cats, have a reflective surface ( tapetum) on the back of the eye behind the sensory receptors (left image above). When light first enters the eye, some light is detected by the sensory receptors. The light not detected by the sensory receptors continues onto the reflective surface at the back of the eye. This light is then reflected outward toward the sensory receptors, providing a second opportunity for detection. This feature produces two results. First, the outward reflection results in the shining of the cat's ey ...
