Global warming, a cause for hunger
|
view preview
A lack of sea ice caused by global warming meant this polar bear was unable to hunt seals and died of starvation. The carcass was found in northern Svalbard, Norway, far from its normal range, where he probably was looking for food.

Curvy trees
|
view preview
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 ...

The plastisphere
|
view preview
Much of the debris in our oceans consists of small fragments of detritus no larger than a fingernail. These confetti-like plastic pieces act as microbial reefs – their own ecosystems – in the vast open ocean. Scientists are studying them to help better understand the predation and symbiosis in these mini ecosystems themselves and also how they are affecting the ocean and its other communities on a broader scale.

Ring trick

Belugas apparently fashion their own entertainment by creating bubble rings and then catching them. A beluga at Sea World Kamogawa, near Tokyo, was snapped in the act, and another at the Shimane Aquarium has been seen performing the trick.

An animal we'll never see again

Australia's iconic Tasmanian Tiger was hunted to extinction in the 1930s - but it may have already been doomed by an extremely small gene pool, according to a new study that stresses the fragility of isolated species.

Ever seen a potoo?

view preview
Potoos are a small New World family of solitary and nocturnal birds. Most are so poorly known they seem more fiction than substance, their gruff or wailing cries ghostly delusions of the dim nocturnal world they inhabit.

Massive drain plug

The Monticello Dam holds back Lake Berryessa in Napa County, California, USA. The morning glory spillway associated with the dam is the largest in the world; it is a funnel-shaped outlet that allows water to bypass the Monticello Dam when it reaches capacity (1370 m³/s). The Glory Hole is located about 61m from the dam; the distance from the funnel to the exit point - which is situated in the south side of the canyon - is about 213m. The outside diameter is 22m, slowly narrowing to 8.5m at the exit. Water spills over the lip of the Glory Hole when the lake reaches 1,976,037,908 cubic metres (1,602,000 acre-feet). The spillway is designed to handle a maximum of 1,370,319 litres of water per second (362,000 gallons of water per second); this ha ...

Blood of Heroes from ancient times

Elafonisi Beach on the Greek island of Crete has pastel pink sand! That rosy hue is caused by tiny particles of pink shells and coral that have been ground down over many years of erosion.

A parrot with a wicked hairstyle
|
view preview
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. ...

Next time you experience acne, try not to remember this

Demodex folliculorum and Demodex brevisare are parasitic mites that particularly favour the hair follicles of eyebrows and eyelashes and measure a mere fraction of a millimeter long. They crawl about your face in the dark to mate and then crawl into the pores to lay their eggs and die. Healthy adults have around one or two mites per square centimetre of facial skin, though people with the condition rosacea can have 10 times more. Demodex does not have an anus and therefore cannot get rid of its faeces. Instead, their abdomen gets bigger and bigger, and when the mite dies it decomposes and releases its faeces all at once into the pore. ...

Danger lies below

An unlikely happy ending for the chemical weapon containers that were dumped in the Pacific Ocean after World War II - US scientists have discovered an array of sponges, crabs and anemones that have made them home. The barrels are still filled with unknown substances that threaten other species in the area, but these opportunistic creatures at least are thriving despite all odds.

Say hello to the umbrellabird! The Umbrellabird is a large, tropical species of bird that is found inhabiting the rainforests of Central and South America. There are three different species of Umbrellabird which are the Long-Wattled Umbrellabird, the Amazonian Umbrellabird and the Bare-Necked Umbrellabird all of which live in slightly different areas. All three species are relatively similar in appearance with an umbrella-like crest on the top of their heads (for which they were named) and a pendant-shaped inflatable pouch on their throats. They are the largest species of perching bird (Passerine) in South America, but populations are currently falling mainly due to habitat loss. ...

The best camouflage
|
view preview
The Buff-tip moth ( Phalera bucephala) is a remarkable species that has developed a unique strategy to evade predators. When at rest, this moth cleverly disguises itself as a broken stick, blending seamlessly with its surroundings. The moth's wings are intricately patterned and colored to mimic the texture and appearance of a twig, complete with jagged edges and bark-like markings. This exceptional camouflage allows the Buff-tip moth to remain virtually invisible to predators such as birds and small mammals that may otherwise consider it a potential meal. By adopting this disguise, the moth gains a significant advantage in survival, as it can confidently rely on its remarkable mimicry to go undetected in its natural habitat. This fascinating ...
