A team of scientists from Montreal’s McGill University have successfully formed a circuit between two wires which were separated by a gap of only 15 nanometers – that’s about the width of 150 atoms. It is reportedly “the first time that anyone has studied how the wires in an electronic circuit interact with one another when packed so tightly together.” Along with being one of the smallest electronic circuits ever created, it has also led to a discovery that may have big implications for the world of computing.  Read More

A cross-section of engineered cartilage tissue, which initially incorporated fast-degradin...

Injuries involving torn or degraded joint cartilage can be very debilitating, especially since that cartilage is incapable of healing itself, past a certain point. It's not surprising, therefore, that numerous scientists have been working on ways of either growing replacement cartilage outside of the body, or helping the body to regrow it internally. Just a few of the efforts have included things like stem cell-seeded bandages, bioactive gel, tissue scaffolds, and nanoscale stem cell-carrying balls. Now, researchers from Cleveland's Case Western Reserve University have announced something else that shows promise - sheets of mesenchymal (bone and cartilage-forming) stem cells, permeated with tiny beads filled with the growth factor beta-1.  Read More

Alexei Efros and his team of cunning robotics researchers at Carnegie Mellon University have developed an image matching algorithm with which computers can identify similar images regardless of medium. Like humans, the system can match sketches and paintings with photographs of similar subjects, and so perform tasks that have traditionally posed problems to machines, such as pairing a simple sketch of a car with a photograph of the same.  Read More

Ants. What a pest. Once you get them in your house it can be a real mission to get rid of them. But it seems the Golden orb web spider has developed a way to keep its home clear of the little buggers. The secret uncovered by researchers from the National University of Singapore (NUS) and the University of Melbourne relates to a chemical compound the spider adds to its web that appears to repel ants. So not only are spider webs providing inspiration for better adhesives and stronger materials, they may also provide the basis for new, environmentally friendly, ant-repelling pesticides.  Read More

A duck pond may seem like the ideal place to spend a peaceful spring afternoon, but during mating season it can look like the scene of a gang attack. Though ducks as a species are famously monogamous, unattached drakes can be extremely aggressive. They attack any female in sight in a mating frenzy that often ends in the injury or death of the victim. This has resulted in the ducks developing ways to prevent unwanted matings and the drakes ways to overcome their defenses. Researchers in North America are developing a novel way to study this "evolutionary arms race" that uses high-speed cameras, force transducers and model duck oviducts made of glass.  Read More

Senseg's technology would allow you to feel textures on a tablet's screen

What if you could feel what's on your television screen? Tech company Senseg is working on a way for you to someday be able to do just that, and recently demonstrated a prototype tablet that is already able to make that magic happen.  Read More

A Harvard computer scientist has created a digital 'face transplant' system, that could be...

If you've seen the film The Social Network, then you might have wondered about the identical Winklevoss twins - were a real-life pair of twins cast for the roles, or was it a bit of Hollywood magic? Well, it was magic. Although two different actors' bodies were used, their faces both belonged to actor Armie Hammer. After the movie was shot, the body double's face was digitally replaced with Armie's. While such computer-enabled face-swapping trickery has so far been available only to feature film-makers with deep pockets, that could be about to change, thanks to research being conducted at Harvard University.  Read More

Virtual photons bounce off a 'mirror' that vibrates at almost the speed of light. The roun...

A perfect vacuum is impossible to achieve, at least in theory. As anyone with any interest in quantum physics would know, the vacuum is full of various particles that fluctuate in and out of existence. These "virtual" particles have been the focus of scientist, Christopher Wilson. Working with his team at Sweden's Chalmers University of Technology, Wilson has succeeded in producing real photons from these virtual photons. Which, in layman's terms, means that they have created measurable light ... from nothing.  Read More

The Lightning Foundry's 1:12 scale prototype in action

Calling all Tesla fans! Electrical engineer Greg Leyh and his team at the Lightning on Demand organization (LOD) in California are raising the funds necessary to build the world's largest twin Tesla coils (ten stories high, about 120 ft/37 m) that will be capable of generating electric arcs more than 200 feet (60 m) long. Dubbed the "Lightning Foundry," the project currently consists of a working 1:12 scale prototype. When complete, a towering pair of coils will fill a football field-sized area with massive electric bolts that researchers hope will reveal some of the mysteries of this beautiful but deadly force.  Read More

Norwegian scientists are developing a capsule that they say will be able to transmit live ...

Although we may not yet have reached the stage where manned submarines can be shrunken down and placed inside the body, à la the movie Fantastic Voyage, current technology does allow us to do something almost as impressive – it is now possible to obtain images of the inside of the intestinal tract, by getting patients to swallow a camera-equipped capsule. Japanese company RF System Lab reported success using its Norika 3 RF Endoscopic Robot Capsule to transmit live video from inside test subjects back in 2004, while just last year Olympus announced the creation of a similar device. Now, Norwegian researchers are stating that they are in the process of developing the “next generation” of camera pill.  Read More
