This is a remote forest in Western Poland, where 400 pine trees have grown with a curvature in their trunk structure and it turns out that no one really knows exactly what caused it. There are, however, a few theories:

1) The main theory seems to suggest that this is the result of human interference. It is believed that this is a tree farm and the trees were forced to grow horizontally in their youth to make a carpenters life easier. The curved shape can be induced by laying a heavy object over a young tree stem. Phototropism will cause the stem beyond the heavy object to grow toward the sky, while the growing stem beneath and behind the heavy object will develop what is called morphogenetic compression wood - which ultimately makes the curv ...

In 1937, a scientist named Carothers died at the young age of 41, desolated that he had not made his mark in the scientific world. His invention, Nylon, was to become one of the most commonly used plastics in the world. Nylon is used in toothbrushes, ropes and fabric for parachutes and clothing.

In the last century, plastics (synthetic polymers) have been so ubiquitous that it is difficult to imagine life without it. But what happens to it when we longer have use for it? Where does it go when we throw plastic out?

Overhunting is one reason for wildlife population decline, but do these animals even know what we’re doing to them? New research suggests that they do. Woolly monkeys in the Amazon were observed to react differently to people in their territory, depending on the behavior of the human.

In areas where hunting is heavy, humans gathering food or performing research do not elicit much of a response from the monkeys. Hunters, however, result in the monkeys becoming very quiet and motionless. In quieter areas where human contact is less frequent, the monkeys are more wary of the researchers and gatherers. This indicates that the monkeys are behaving based on experience.

The long term advantage of this behavior is uncertain. Woolly monkeys are highl ...

These are rainbow eucalyptus trees (Eucalyptus deglupta) and they hail from the Philippine Islands.

The trees get their name from the striking colours observed on their trunks and limbs. Although it may look like someone took a paintbrush to them, these colours are entirely natural. Unlike most trees, the rainbow eucalyptus does not have a thick, cork-like layer of bark on its trunk. The bark is smooth and as it grows it 'exfoliates' layers of spent tissue. This exfoliation technique occurs at different stages and in different zones of the tree.

Once a layer is shed, a new fresh green bark is exposed. As this new bark ages, we can see the tissue change colour to dark green followed by a bluish colour, then to purple and pink-orange and then f ...

Meet olinguito, or Bassaricyon neblina, the first species of carnivore discovered in the Western Hemisphere in 35 years. This cute teddy bear-like nocturnal mammal is native to Central and South America, and spends most of its time in the treetops, coming down to the forest floor occasionally to eat fruits such as guava.

This is a Palm Cockatoo, also know as the Goliath Cockatoo.

Palms are distinguished by their size, huge beak (second only to the Hyacinth Macaw among psittacines and largest proportionate to size), solid black feather coloration, large open crest, bare red cheeks, and red and black tongue. You have to see their tongues to believe the coloration. It's amazing.

Palm Cockatoos are severely threatened. They are CITES Appendix I birds and are protected in Australia.

As a testament to their rarity, typical prices in the U.S. for Aterrimus Palms are around $8000 and Goliaths around $14,000. Perhaps contributing to their rarity is the fact that, according to both Low and Forshaw, they lay only one egg per clutch.
