Dolphin

You can tell a lot about a dolphin by its breath (Photo: Shutterstock)

If you want to get a picture of wild dolphin populations' health, it's typically necessary to capture some of the animals and then obtain blood samples or skin biopsies. Needless to say, it's hard work, and the dolphins tend not to like it. Soon, however, it may be possible to gather the same information using a device that samples their breath.  Read More

The DOL-Fin is a hydrofoil for your feet

Besides being able to fly like a bird, many people fantasize about having the ability to swim like a dolphin. Divers already have the option of replacing their two regular swim fins with one fluke-like flexible rubber monofin, although aerospace engineer Ron Smith claims that his invention is much more effective. Known as the DOL-Fin, it incorporates a wide rigid hydrofoil-type fin.  Read More

Dolphins' ability to tell the difference between fish and bubbles has inspired the creatio...

Chances are, you know that dolphins use sonar to locate and stun prey underwater. You might also know that they create "bubble nets," in which they trap fish inside a ring of air bubbles that they blow while swimming in a circle. With all those distracting bubbles suspended in the water, though, their sonar needs to work in a special way in order to pick out the fish. Scientists have copied that sonar system, to create a type of radar that could differentiate between ordinary objects and things like explosive devices.  Read More

Scientists have created an underwater speaker for use in studying dolphin communication (P...

While there’s little doubt that dolphins are saying something to one another with all their clicks, squeals and whistles, we’re still not entirely sure just what it is that they’re communicating. We may be getting closer to figuring it out, however, as Japanese scientists have created an underwater speaker that’s capable of playing back the creatures’ entire acoustic range. The next step - see how they respond.  Read More

Scientists are working on an underwater device that could facilitate two-way human-dolphin...

Despite his annoyingly cutesy synthetic voice, Darwin the Dolphin on the TV series SeaQuest DSV did present an intriguing possibility – what if we could create a dolphin language translator? Such a device may no longer be limited to the realm of science fiction, as two scientists are currently developing an underwater computer that they hope to someday use for two-way communications with wild dolphins.  Read More

The Seabreacher not only looks like a dolphin, it can dive and jump like one, too

Gizmag covered this amazing dolphin-like watercraft almost three years ago. At that stage, the Seabreacher - a unique submersible vessel - was just a prototype. Now, you can own your own, make like Flipper, and dive, roll and jump while staying warm and dry in the comfort of the sealed cockpit. Oh, that is, if you have a cool USD$50,000 burning a hole in your wallet.  Read More

The space age looking AirPenguins

The latest example of biomimicry in robotics to cross our desk is from German electrical automation company Festo, which has used the shape of the acquatic, flightless bird to construct two different types of bionic penguins. The AquaPenguins use the bird's hydrodynamic body contours and wing propulsion to allow the robot to maneuver in cramped spaces, turn on the spot and, unlike their real-life counterparts, swim backwards. The larger helium-filled AirPenguins use the same principles to lift the usually flightless bird into the air.  Read More

Atlantis Hotel Dubai

The recently-launched luxury Atlantis hotel rises towards the sky from the man-made island of Palm Jumeirah, but unlike it’s mysterious namesake, this Atlantis is unlikely to get ‘lost’. The ocean-and-aquatic themed resort is impressive, and not surprisingly everything about it is big - from the development price of US$1.5 billion to its size (it's spread over 46 hectares of reclaimed land) and its 1, 539 rooms. It also features a massive 17 hectares of water park activities and an 11 million liter marine habitat that is home to more than 65,000 marine animals.  Read More
