Mother Tiger Adopts Baby Piglets
In a zoo in California, a mother tiger gave birth to a rare set of triplet tiger cubs. Unfortunately, due to complications in the pregnancy, the cubs were born prematurely and due to their tiny size, they died shortly after birth.
The mother tiger after recovering from the delivery, suddenly started to decline in health, although physically she was fine. The veterinarians felt that the loss of her litter had caused the tigress to fall into a depression. The doctors decided that if the tigress could surrogate another mother's cubs, perhaps she would improve.
After checking with many other zoos across the country, the depressing news was that there were no tiger cubs of the right age to introduce to the mourning mother. The veterinarians decided to try something that had never been tried in a zoo environment. Sometimes a mother of one species will take on the care of a different species. The only orphans" that could be found quickly, were a litter of weaner pigs. The zoo keepers and vets wrapped the piglets in tiger skin and placed the
babies around the mother tiger. Would they become cubs or pork chops??
Take a look........ you won't believe your eyes!!

How to solve the toxic asset problem: give them to bank executives as bonuses
From James Kwak:
Why not say that all bank compensation above a baseline amount - say, $150,000 in annual salary - has to be paid in toxic assets off the bank’s balance sheet? Instead of getting a check for $10,000, the employee would get $10,000 in toxic assets, at their current book value. A federal regulator can decide which assets to pay compensation in; if they were all fairly valued, then it wouldn’t matter which ones the regulator chose. That would get the assets off the bank’s balance sheet, and into the hands of the people responsible for putting them there - at the value that they insist they are worth. Of course, the average employee does not get to set the balance sheet value of the assets, and may not have been involved in creating or buying those particular assets. But think about the incentives: talented people will flow to the companies that are valuing their assets the most realistically (since inflated valuations translate directly into lower compensation), which will give companies the incentive to be realistic in their valuations. (Banks could inflate their nominal compensation amounts to compensate for their overvalued assets, but then they would have to take larger losses on their income statements.)
We can dream, can’t we?

The Chameleon Guitar
Natural wood, with its unique grain patterns, is what gives traditional acoustic instruments warm and distinctive sounds, while the power of modern electronic processing provides an unlimited degree of control to manipulate the characteristics of an instrument's sound. Now, a guitar built by a student at MIT's Media Lab promises to provide the best of both worlds.
The Chameleon Guitar -- so named for its ability to mimic different instruments -- is an electric guitar whose body has a separate central section that is removable. This inserted section, the soundboard, can be switched with one made of a different kind of wood, or with a different structural support system, or with one made of a different material altogether. Then, the sound generated by the electronic pickups on that board can be manipulated by a computer to produce the effect of a different size or shape of the resonating chamber.

Pedal Powered Sub to Try and Cross Atlantic
It may sound like a crazy stunt dreamed up by an adrenalin junkie, but the plan, dubbed the "Subhuman project", has attracted serious attention from marine biologists. That's because the sub, when it takes to the seas later this year, could for the first time allow them to explore the upper layers of the ocean silently and unobtrusively, revealing marine life as it has never been seen before.
Ciamillo, a machinist by training and an inventor by trade, does have a track record in underwater exploration. In 1997 he made his name designing a James Bond-style underwater propulsion vehicle called the Hydrospeeder, which looks something like an underwater motorbike. Although the company that sold the Hydrospeeder later folded, Ciamillo remained keen to speed up underwater exploration. "I found myself frustrated by how slowly you move under water, especially with a bunch of dive gear on your back," he says. "It's like dropping someone in the middle of the forest in a wheelchair."
So, in collaboration with marine biologist Frank Fish of West Chester University in Pennsylvania, who specialises in the biomechanics of cetacean swimming, Ciamillo designed a carbon-fibre "tail" for divers, called the Lunocet. Modelled on Fish's CAT scans of dolphin flukes, the Lunocet has a hydrofoil profile, like an underwater wing. "As dolphins move their tails up and down, they create a forward-directed lift," says Fish. This lift becomes thrust, and lots of it: dolphins have been clocked at 54 kilometres per hour. They can turn 80 per cent of their energy into thrust, compared with a paltry 3 per cent or so for unaided human swimmers and about 10 per cent for people wearing ordinary swim fins.
The Lunocet operates in a similar way, to enable the diver to swim as efficiently as possible. A dolphin-tail configuartion has previously been shown to be up to 15 per cent more efficient at transforming energy into forward motion than even the best rigid propellers.

'Immortal' jellyfish swarming across the world
The Turritopsis Nutricula is able to revert back to a juvenile form once it mates after becoming sexually mature.
Marine biologists say the jellyfish numbers are rocketing because they need not die.
Dr Maria Miglietta of the Smithsonian Tropical Marine Institute said: "We are looking at a worldwide silent invasion."
The jellyfish are originally from the Caribbean but have spready all over the world.
Turritopsis Nutricula is technically known as a hydrozoan and is the only known animal that is capable of reverting completely to its younger self.
It does this through the cell development process of transdifferentiation.
Scientists believe the cycle can repeat indefinitely, rendering it potentially immortal.
While most members of the jellyfish family usually die after propagating, the Turritopsis nutricula has developed the unique ability to return to a polyp state.
Having stumbled upon the font of eternal youth, this tiny creature which is just 5mm long is the focus of many intricate studies by marine biologists and geneticists to see exactly how it manages to literally reverse its aging process

Boy Invents Invisible Sticket to Want Birds About Windows
Eighth grader Charlie Sobcov wants to stop birds from dying in collisions with windows, but he doesn't want to ruin anybody's view.
For his latest school science fair project he has invented painted, plastic decals that can be placed — discreetly — right in the middle of a window pane.
"This paint is a colour that birds can see but humans can't," he said Wednesday on CBC Radio's All in a Day. "It's like putting a big stop sign in the middle of the window."
The colour is ultraviolet, beyond the range of colours visible to humans. That means the "stop sign" lets birds know the window is solid, but is nearly invisible to humans.
Similar flying falcon-shaped decals already exist on the windows of some buildings, but unlike Sobcov's, they are black and can obstruct part of the window.
