Fish

Who wouldn't want to wear clothing inspired by these guys?

Hagfish are super-slimy eel-like fish that live on the sea floor, where they feed on the carcasses of other sea creatures. Before you start disliking them too much, however, take note – synthetic fabrics of the future may be inspired by their slime.  Read More

The Home Aquaponics Kit provides the perfect opportunity to educate kids about the process...

Many of us have completely lost sight of where the food we eat comes from. As long as the product is sitting on the shelf when we visit the supermarket, we pay little attention to the process that led to it being there. The Home Aquaponics Kit is designed to counter this ignorance by educating children in the process involved in growing and cultivating food using a self-cleaning fish tank and a self-maintaining herb garden.  Read More

Wave Glider robots are being deployed as part of an extensive marine life tracking network...

If you’ve ever sat in a beach-side coffee house wondered if there was a white shark in the vicinity, then wonder no more because now there’s an app for that. A team of Stanford University researchers lead by Prof. Barbara Block is deploying a fleet of static buoys and Wave Glider robots to turn the waters off the coast of San Francisco into a huge Wi-Fi network to track tagged fish and animals. This will allow scientists to better understand sea life movements, but the project also includes offering a free app to the public that will allow them to track northern California white sharks on their tablets and smartphones.  Read More

Hilary Bart-Smith's robotic cow-nosed ray

Sometime in the future, perhaps sometime soon, the robotic jellyfish, octopi and fish cruising the world’s oceans may have to make way for one other companion – the robotic ray. A team led by University of Virginia engineering professor Hilary Bart-Smith has created such a “creature,” in hopes that its autonomously-operated descendants may someday help us humans explore and study the sea, or possibly perform surveillance for the military.  Read More

The University of Exeter's engineered zebrafish

Researchers at the University of Exeter have created a transgenic zebrafish which produces highly targeted green fluorescent signals when exposed to environmental estrogens.  Read More

NYU-Poly's tail-flapping biomimetic fish

A couple of years ago, a team of scientists from the University of Leeds succeeded in getting live stickleback fish to follow a computer-controlled “Robofish” as it was moved through their aquarium. Part of the reason for the experiment was to learn about fish behavior, in hopes that human interference in their migration routes could be minimized. While the Robofish was simply a plaster model, researchers from the Polytechnic Institute of New York University recently conducted a similar experiment, but using an actual tail-flapping robotic fish. Their discoveries could help save wild fish populations in the event of environmental disasters.  Read More

EM Observe is an electronic system, that remotely monitors fishing vessels' catches

In an effort to save the world's oceans from overfishing, many countries now require commercial fishing vessels to bring along an observer, who checks that the crew aren't exceeding their catch limits. That observer takes up cabin space on the boat, however, plus they require a salary, and probably aren't made to feel particularly welcome by the crew members. This month, however, a Spanish purse seiner became the world's first tropical tuna-fishing vessel to try out something different - an electronic monitoring system. Designed by Archipelago Marine Research, the EM Observe system is already in regular use in the company's home province of British Columbia, Canada.  Read More

The piranha-bite-proof scales of the Arapaima fish could serve as the inspiration for body...

Here's a question - if piranhas are so ferocious and will attack anything, why aren't they the only fish in the Amazon? Well, in some cases, it's because other fish possess bite-proof armor. The 300-pound (136-kg) Arapaima is just such a fish. In the dry season, when water levels get low, Arapaima are forced to share relatively small bodies of water with piranhas. Their tough-but-flexible scales, however, allow them to remain unharmed. A scientist from the University of California, San Diego is now taking a closer look at those scales, with an eye towards applying their secrets to human technology such as body armor.  Read More

Scientists have created a rudimentary data storage device using salmon DNA (Photo: Isaac W...

Salmon ... they’re good to eat, provide a livelihood for fishermen, are an important part of their ecosystem, and now it seems that they can store data. More specifically, their DNA can. Scientists from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a “write-once-read-many-times” (WORM) memory device, that combines electrodes, silver nanoparticles, and salmon DNA. While the current device is simply a proof-of-concept model, the researchers have stated that DNA could turn out to be a less expensive alternative to traditional inorganic materials such as silicon.  Read More

A new study suggests that exposure to titanium oxide nanoparticles causes rainbow trout to...

In just the past few years, nanotechnology has brought technological advances in almost every field imaginable – patches that regenerate heart tissue, water-powered batteries and better biofuels are just a few examples. As with just about any new technology, however, concerns have been raised regarding its safety. We’ve never experienced anything quite like it before, so how far should we trust it? According to a recent study conducted at the University of Plymouth, the answer to that question might be “Not very far.” In tests on rainbow trout, titanium oxide nanoparticles were found to cause damage to the brain and other parts of the central nervous system.  Read More
