Amazing waves/ surf photos



From Less than Dot.

This guy is from Oahu, but he is gaining International fame.
He's a surfer himself and often gets wiped out just getting the shot.
And you can see why!
These incredible images of waves were taken by the
number one photographer of surf: Clark Little.
He has dedicated his life to photographing the waves
and has published a selection of the the best images of his career.
He captures magical moments inside the "tube", as surfers say.

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

Futuristic Atlantis Hotel In Dubai




Looks a lot like the one here in the Bahamas. Look forward to visiting both. ;-)

The Bionic Dolphin



Two years ago Winter was the dolphin that could not swim.

Instead of powering through the water with a flick of her tail, the bottlenose could barely waggle from side to side.

She had lost her tail in a crab trap at just two months old and was found floating in distress off the coast of Florida.

She may never be the most elegant dolphin who ever swam but, as she splashes about in the aquarium, it is safe to say that she probably doesn't care.

Giant Star Fish


WELLINGTON, New Zealand (AP) — Scientists who conducted the most comprehensive survey to date of New Zealand's Antarctic waters were surprised by the size of some specimens found, including jellyfish with 12-foot tentacles and 2-foot-wide starfish.

Amazing Flipping Ship


The FLIP research vessel (Floating Instrument Platform) is the only ship in the world having the ability to flip from a horizontal position to a vertical position while at sea.

The FLIP ship is designed to study wave height, acoustic signals, water temperature and density, and for the collection of meteorological data.

FLIP is 108 meters long and weighs 700 long tons. According to Alan Bellows, “when in horizontal traveling mode, the long, hollow ballast area trails behind.

Dolphin Talks to Whales and Rescues Them


Moko the dolphin
A dolphin has come to the rescue of two whales which had become stranded on a beach in New Zealand.

Conservation officer Malcolm Smith told the BBC that he and a group of other people had tried in vain for an hour and a half to get the whales to sea.

The pygmy sperm whales had repeatedly beached, and both they and the humans were tired and set to give up, he said.

But then the dolphin appeared, communicated with the whales, and led them to safety.

The bottlenose dolphin, called Moko by local residents, is well known for playing with swimmers off Mahia beach on the east coast of the North Island.

He added: "The dolphin did what we had failed to do. It was all over in a matter of minutes."
