The Desktop Jellyfish Tank is an aquarium designed specifically for the keeping of jellyfi...

Jellyfish are definitely fascinating creatures, that are almost hypnotizing to watch ... you could say, they’re the lava lamps of the animal kingdom. Unfortunately for aquarists, however, they also can’t be kept in a regular aquarium, as they’ll get sucked into the water filtration intakes. That’s why Duke University Biology and Environmental Science alumnus Alex Andon started experimenting with adapting regular aquaria to make them jellyfish-friendly. After having some success with selling these converted tanks online, he decided to start making them from scratch. His San Francisco company, Jellyfish Art, is now marketing them as the Desktop Jellyfish Tank.  Read More

Paul's Duplex lever allows disabled cyclists to activate both brakes with one hand

While commuter bicycles can generally get by with a rear-wheel-only coaster brake, mountain and cyclocross bikes require both front and rear brakes – along with the hand levers used to activate them. Although this doesn’t pose much of a challenge for most riders, it does for those who only have the use of one hand. One possible solution is to use a system that joins both brake cables to one common end, which then goes into a conventional lever. Another solution, however, is to use Paul Component Engineering’s dual-cable Duplex lever.  Read More

Air Swimmers are remote-control model fish, that swim through the air

Should someone tell you “Last night, I saw a great white shark swimming through my living room,” don’t assume that they’re crazy. It could be that what they saw was an Air Swimmer. The remote-control toys (which are available as a shark or a clown fish) are able to swim through the air, turning, diving and climbing on command. Now all we need is an RC model penguin, that flies underwater.  Read More

A scientist has proposed a 'fluid flow cloak,' which might reduce the drag on ships' hulls...

North Carolina’s Duke University has been grabbing some headlines over the past few years, due to research carried out there involving the use of metamaterials for creating functioning invisibility cloaks. Just this month, Duke researchers announced that they had developed another such material that could be used to manipulate the frequency and direction of light at will, for use in optical switching. Now, Duke’s Prof. Yaroslav Urzhumov has proposed that metamaterials could also be used to drastically reduce the drag on ships’ hulls, “by tricking the surrounding water into staying still.”  Read More

Goodyear is developing a system that would automatically keep tires inflated to the proper...

It’s important to keep your tires sufficiently inflated, both for the sake of the tires themselves, and in order to maximize the performance and fuel economy of your vehicle. The problem is that for many of us, we only think to check our tire pressure when heading out on a long road trip – if even then. With Goodyear’s Air Maintenance Technology (AMT), however, that shouldn’t matter. The system, which is currently in development, would automatically keep tires topped up to the proper pressure.  Read More

Polish designer Stanislaw Ploski's Bonobo bicycle has a frame made from bent plywood

One of the nice features of some bent plywood chairs is the fact that they spring up and down, so they have some give when you first sit down in them. Well, Polish designer Stanislaw Ploski has taken that flex appeal, and applied it to a one-of-a-kind bicycle. Named Bonobo, the bike’s frame is made from curved, laminated layers of plywood.  Read More

Dutch artist Olaf Mooij's 'braincar' records images of its travels, then projects them on ...

Have you ever questioned what it would be like if a car “could experience with a kind of consciousness its own passage through spacetime”? Well, Rotterdam artist Olaf Mooij has. It drove him to create “braincar,” which is ... well, it’s a car with a brain on the back. By day, the car captures stills and videos of its travels down the roads. By night, it remixes those images, then projects them on the inside of its translucent brain.  Read More

Scientists are experimenting with using genetically engineered spider silk proteins in the...

Spider silk is pretty amazing stuff. Pound for pound, it has a tensile strength close to that of steel while being one-fifth as dense, it’s tougher than Kevlar, and it can stretch to almost one-and-a-half times its length without breaking. As if that wasn’t enough, it now appears that a genetically engineered version of the substance could be used for delivering genes into human cells.  Read More

Willow Garage has just released the PR2 SE, a lower-priced one-armed version of its PR2 ro...

Among the various scientific/industrial robots in the marketplace, Willow Garage’s PR2 is one that stands out. This is because both its hardware and software are open-source – users are encouraged to share their latest upgrades and customizations with one another. With various parties using a common platform, instead of all having to start from scratch, Willow Garage hopes to move the field of robotics forward faster than would otherwise be possible. To that end, the company recently gave ten PR2s to groups involved in robotics research, to keep for up to two years. This Wednesday, commercial availability of the PR2 SE was announced. It costs US$285,000, which is significantly less than its sibling’s $400,000 price tag – users will just have to work around the fact that it only has one arm.  Read More

Ian Williams and and Anders Warn, with the WilliamsWarn beer brewing machine

Home beer-brewing is sort of like writing a novel – although you might like the idea of having done it, the thought of all the work involved in doing it can be off-putting. If the PR materials are to be believed, however, the WilliamsWarn brewing machine could make the process a lot easier ... and quicker. Unlike the four weeks required by most home brewing systems, it can reportedly produce beer in just seven days.  Read More
