Implant

A implantable material made from a blend of plastics has been developed to regrow damaged ...

Over the past several years, a number of research institutes have been exploring the use of implants made from material with a scaffolding-like structure, as a means of regrowing bone at severe injury sites. Both MIT and Tufts University, for instance, have been working on collagen-based materials. Now, England’s University of Southampton has announced the development of a new type of bone-growing substance, made from plastic.  Read More

This bionic man contains US$1 million worth of artificial limbs, organs, and blood (Photo:...

Are the famous lines "Gentlemen, we can rebuild him – we have the technology" from The Six Million Dollar Man coming true? Perhaps not entirely, but a new Channel 4 documentary entitled How to Build a Bionic Man will demonstrate the current state of the art in artificial limbs, organs, and even blood, through the construction of a 6-foot tall android. The documentary is set to air on British televisions come February 7, but you can learn about what went into it after the break.  Read More

There may soon be help for people who have been rendered functionally deaf by problems of the middle ear. Researchers from Sweden’s Chalmers University of Technology have developed an implant that bypasses the defective middle ear, transmitting sounds to the inner ear by sending vibrations right through the skull bone.  Read More

A new approach to surgical weight-loss installs a self-operated stomach pump  (Photo: Shut...

There's good news and bad news in the fight against morbid obesity. The good news is that there is a new approach to surgical weight-loss which is far less invasive than conventional operations. The bad news is how it works.  Read More

Quadriplegic Jan Scheuermann prepares to take a bite out of a chocolate bar she is guiding...

Earlier this year, a 58 year-old woman who had lost the use of her limbs was successfully able to drink a cup of coffee by herself using a robotic arm controlled by her thoughts via a brain computer interface (BCI). Now, in a separate study, another woman with longstanding quadriplegia has been able to feed herself a chocolate bar using a mind-controlled, human-like robot arm offering what researchers claim is a level of agility and control approaching that of a human limb  Read More

Scientists are looking into treating Alzheimer's disease by applying tiny shocks to the br...

The process of deep brain stimulation involves using a pacemaker-like implanted device to apply controlled mild electrical pulses to specific areas of the brain. In recent studies, it has been used – with some success – to treat conditions such as Parkinson's disease, major depression and Tourette syndrome. Now, in the ADvance Study, researchers at several research centers are exploring its use in restoring memory function to people with Alzheimer’s disease.  Read More

MIT engineers have devised a way to stack neurons to form three-dimensional brain tissue (...

A team of researchers from MIT and Harvard Medical School have devised a cheap way of artificially growing three-dimensional brain tissues in the lab. Built layer by layer, the tissues can take on just about any shape and closely mimic the cellular composition of the tissue found in the living brain. The advance could allow scientists to get a closer look at how neurons form connections, predict how cells of individual patients will respond to different drugs, and even lead to the creation of bioengineered implants to replace damaged brain tissue.  Read More

Max Ortiz Catalan demonstrates how the system works with the aid of electrodes placed on t...

Researchers based at Chalmers University of Technology in Sweden have developed the world’s first thought-controlled, fully implantable robotic arm, which uses an amputee's own nerves and remaining muscles to afford a much more intuitive level of control than previously possible. Initial operations on patients are scheduled to take place during the Northern Hemisphere’s upcoming winter.  Read More

Scientists have used polymer implants to grow new adult brain tissue (Image: Shutterstock)

Using implants made from porous biocompatible materials, scientists have recently been successful in regrowing things such as teeth, tendons and heart tissue, plus bone and cartilage. The materials act as a sort of nanoscale three-dimensional scaffolding, to which lab-cultivated cells can be added, or that the recipient’s own cells can colonize. Now, a Spanish research team has used the same principle to grow new brain tissue – the technique could ultimately be used to treat victims of brain injuries or strokes.  Read More

The basic components of the Argus II Retinal Prosthesis, used in the experiment

Second Sight’s Argus II Retinal Prosthesis is definitely an interesting piece of technology, allowing a blind user to “see” objects, colors and movement in their environment. Ordinarily, this is done with the help of a video-camera-equipped pair of glasses worn by the user. In a recent experiment, however, researchers bypassed the camera, transmitting visual braille patterns directly to a blind test subject’s retina.  Read More
