Colorful trees
|
view preview
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 ...

Bunnies that glow in the dark
|
view preview
Glow-in-the-dark rabbits were born a few days ago at the University of Istanbul, Turkey. To produce the ‘mutant’ bunnies, researchers took two embryos from a pregnant female rabbit, injected them with a fluorescent jellyfish protein, and reinserted them into the female rabbit. The scientists believe this experiment could help in the development of better, more efficient ways to produce medicines.

Blue eggs
|
view preview
Scientists have identified the genetic mutation responsible for the first blue chicken eggs in South American Mapuche fowl and their European descendants, Araucana, 200 to 500 years ago. They used the unique genetic resources conserved by heritage or “fancy” poultry breeders to identify the exact location of the mutation in the genome in blue egg laying chickens and an additional genomic study to reveal the genetic cause of the blue colored eggshell is a harmless ancient retrovirus in the domestic chicken. ...

Baby blue eyes
|
view preview
Waardenburg Syndrome is a rare autosomal genetic disorder that has possible bright blue eyes as one of its qualifying criteria, along with possible deafness (common). Actually, the cause of the blue eyes is a form of albinism that may include patches of non-pigmented skin or forehead hair, regardless of ethnicity. There are four types of Waardenburg Syndrome, with a mix of possible characteristics as the determinant. Medical challenges increase with type. The boy in the picture is displaying two major symptoms of type 1; bright blue eyes and dystopia canthorum, a condition where the inner corners of the eyes are set more widely apart, but with normally distanced eyes. ...

An unrecognized hero
|
view preview
"I believe that at the end of the century the use of words and general educated opinion will have altered so much that one will be able to speak of machines thinking without expecting to be contradicted."Alan Turing (left) was a hero to the British people and the free world whose work cracking the codes of Axis powers saved lives and helped the war effort. He was highly influential in the development of computer science, giving a formalisation of the concepts of "algorithm" and "computation" with the Turing machine, which can be considered a model of a general purpose computer ...

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.

Abortion is a tough lemon to swallow

Take a good look at this premature child. It's hard to deny that it isn't a fully formed human being, though in some parts of the world, abortions at the second and third trimester are perfectly legal Thoughts are welcome.

A peculiar lobster has been discovered

1 out of every 50-100 million lobsters has split coloring. One side is typically a dark brown, while the other side is blue, orange, or red. These individuals usually exhibit traits of both males and females.

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. ...

A computer that can spell out what you're thinking

The program builds on previous research and uses a mathematical model to determine which letter the test subject was thinking about at the time of the scan. Researchers hope to refine this technology in the future in order to reconstruct memories or dreams.
