UC Santa Barbara scientists have replicated the uncanny underwater adhesive capacity of mussels – which has previously inspired a surgical glue – in a versatile and strong synthetic material. The ultra-thin material boasts up to 10 times the effectiveness of prior wet/underwater adhesives, and its low molecular weight and functional properties means that it can be used to boost the performance of existing bulk adhesives, as well as in such varied applications as dentistry, nanofabrication, and underwater repair.
If you like your nights out unusual, then look no farther. Visitors to the Clear Lounge bar in Cozumel, Mexico, are submerged in a 13,000-gal (59,100-l) tank of water while scented oxygen is pumped into their diving helmets. If that sounds mundane, then there's underwater Jenga to keep you occupied.
Aerial drones are great for providing a bird’s eye view of our world. That said, some people are more interested in seeing a fish’s eye view of their local seacoast or lake. Previously, such folks had to build their own underwater remote-operated vehicle (ROV). Three years ago, San Francisco startup OpenROV made things a little easier for them, by offering an ROV kit that users put together themselves. Now, the company is crowdfunding the fully-assembled Trident ROV, which can reportedly be "flown" through the water.
While we've previously seen a number of GoPro accessories
which can keep you shooting when the battery runs out, the PolarPro
PowerGrip H2O is the first we've come across capable of live-charging
the action camera while underwater. Currently looking for funding on
Kickstarter, the PowerGrip H2O is a waterproof selfie stick with an
integrated battery, which can charge a camera at depths of up to 30 m
Researchers at NASA's Jet Propulsion Laboratory have grown underwater chimney-like structures capable of generating enough electricity to power a light bulb. The team linked several of these chimneys to get the required electricity. Their findings indicate that the seafloor equivalents of these chemical gardens might just have contributed the electricity needed for the Earth's first organisms to develop.
Ever wondered what it would be like to attach a GoPro to your fishing line to record all the underwater action on video? It would probably be cool to watch, yet dizzying as the camera freely spins however the water moves it. One of the latest, the GoFish Cam, tries to address this with a little inspiration from the very fish it will be filming.
The stand for the region of Liguria at the Milan 2015 Expo features a project as bizarre-sounding as it is intriguing: an attempt to grow crops underwater, inside air-filled biospheres. It's part of an effort that could prove a low-cost, low-energy solution to grow food in parts of the world where this was not previously possible.
While there are plenty of aerial drones that show us our surroundings
from up in the air, there are far fewer remote-control devices that let
us see what's lurking beneath the surface of the water. Although the Aquabotix Hydroview
is one, at around US$3,000 it certainly isn't cheap. While still not
inexpensive, the newest version of the TTRobotix Seawolf is considerably
less pricey – partly because it incorporates the user's existing GoPro
Starting in April 2011, the European Union CoCoRo (Collective Cognitive
Robots) research consortium has been developing three varieties of
autonomous underwater robots that school together like fish. By doing
so, the little bots can share and learn from each others' "knowledge" of
their environment, acting as a collective cognitive system that's
smarter than any one of its individual parts.
Dubai has more than its fair share of outlandish buildings, but 8 + 8 Concept Studio's recently-revealed proposal for an underwater tennis center would probably take the biscuit for the craziest yet – in the unlikely event it is ever built, anyway ...
