Two male squirrel monkeys now see the world in an entire new way in full color.Female squirrel monkeys can see in color, but male squirrel monkeys are normally red-green colorblind because they lack pigments in the retina that notice those wavelengths of light.
Now, researchers have performed gene therapy that permitted two male squirrel monkeys named Sam and Dalton to produce proteins that detect red light. As soon as the red-light-harvesting protein was made in the monkeys' eyes, the animals were able to distinguish between red and green spots in color vision tests, Jay Neitz of the University of Washington in Seattle and his collaborators report online September 17 in Nature.
The experiment wasn't supposed to work, Neitz says. People born with cataracts don't develop nerve relations that help the brain make sense of messages sent by the eye. If the defect isn't corrected early, these people stay essentially blind even if their eyes return to full function later.
Because there was no reason to assume color vision was different from other types of vision, the team had assumed it would not be possible to reverse the deficit in an adult animal.
Neitz polled experts in the vision field on whether they thought producing photoreceptors in colorblind adult monkeys could give color vision. "Every single person said, "absolutely not.'" But the researchers decided to move forward with the experiment to see if they could get the pigment protein to be made in the eye.
Male monkeys lacking the red photoreceptor protein were given injections of a virus carrying a gene for the protein.
Levels of the protein slowly rose in some retinal cells. After 20 weeks, Neitz and his colleagues started to see differences in the way Sam and Dalton performed on daily color vision tests. Around that time, protein production levels peaked and the monkeys have maintained stable color vision for two years since treatment.
Still, the monkeys' actual sensation of color what it looks like to them remains a mystery?
"The achievement is technically amazing and conceptually very cool," says Melissa Saenz, a neuroscientist at Caltech in Pasadena, Calif. But even though the monkeys can distinguish some new wavelengths of light, "there's no proof that the monkeys recognize a new dimension of color," she says. For example, the monkeys may now perceive red and green as different shades of yellow and blue, colors the animals already knew.
"If it doesn't involve experiencing new sensations of color, it would not dramatically change the experience of colorblind people if the treatment were valid to humans," Saenz says.

WikiLeaks is an international non-profit media organization that publishes submissions of otherwise unavailable documents from anonymous sources and leaks. Its website, launched in 2006, is run by The Sunshine Press. Within a year of its launch, the site claimed a database that had grown to more than 1.2 million documents.
These odd circles may look like messages from aliens or the humorous graffiti of penguins, but it’s in fact the ephemeral
Because of the steady threat of losing the entire piece to a sharp gust of wind, a team of helpers assisted in the creation of the gigantic masterpiece. Eight people in all got out onto the ice and used brooms to brush the snow into simple, elegant circles. The work was chronicled on The Anthropologist, a site that features new artwork for Anthropologie.
According to the creator of Reborn puppets, an English artist Deborah King, her creations are not toys for children. All of these “substitutes for the child” are intended to brighten up the gray days of adults, to find some purpose to unspent parental love.
Group harrington are producing half scale cars allegedly aimed for kids, but adults can cram into them to. They build accurate half scale of the legendary timeless typical like the "Porche 356", "Mercedes Benz 300SL" "Jaguar E-type" "Bugatti T35" and the more recent "Willys Jeep". They are produced in both petrol and electric models. They can build your own car to order, you can choose any colour (metallic or solid) for the body, and any colour for the interior.
The feature “Amazon Alive! A Decade of Discoveries 1999-2009,” gives an account of the 257 types of fish, 55 species of reptiles, 216 species of amphibians, 16 types of birds and 39 types of mammals. It also discovered 637 species of plants. One of the cutest things that they have probably discovered, is the Inia Boliviensis.
Astronomers have discovered the 500th exoplanet outside our solar system, a database maintained by a French astronomer says. Astrobiologist Jean Schneider of the Paris-Meudon Observatory, who compiles the Extrasolar Planets Encyclopedia, says less than 20 years after the discovery of the first exoplanet he has logged No. 500, discovered Nov. 19, SPACE.com reported.

Ladybower Reservoir is a large Y-shaped reservoir, the lowest of three in the Upper Derwent Valley in Derbyshire, England. The River Ashop flows into the reservoir from the west; the River Derwent flows south, initially through Howden Reservoir, then Derwent Reservoir, and finally through Ladybower Reservoir. Its longest dimension is just over 3 miles (5km), and at the time of construction it was the largest reservoir in Britain (1943)





Another thing that will tell you that hermits are pretty ingenious creatures is their pattern when it comes to breeding. When the female hermit crab needs to lay her eggs, she usually rushes to the shore of the ocean and then lays her eggs there. She doesn’t just go and put them on the shore. No. She actually makes a hole and then lays eggs there in ample. She then covers her eggs with sand and then leaves them to hatch. After hatching, the baby hermits run to the ocean from where they grow up.







But in new research, recently published online in the journal Oikos, Rockwell and his team show that the currently plentiful snow goose population is in no risk from the bears. In fact, the eggs might provide a valuable backup food source as polar bears are forced to end their seal hunts early. For one thing, a snow goose egg is about twice the size of a chicken egg, but it is much more nutritious, said Rockwell, a research connect at the American Museum of Natural History and a professor at the City University of New York.
