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

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

Generally speaking, injured cartilage doesn’t heal well ... if at all. In recent years, however, scientists have successfully regrown cartilage at injury sites, using things like hydrogel, microspheres and collagen-based nano-scaffolding. Now, a team of scientists led by Prof. James Yu of North Carolina's Wake Forest Institute for Regenerative Medicine have developed something else – a 3D printer that creates implantable cartilage.  Read More

Regular implantable defibrillators (like this one) may save patients' lives, but also infl...

While regular pacemakers attempt to rectify arrhythmias (irregular heart beat rhythms) using constantly-delivered electric pulses, implantable cardioverter defibrillators do something a bit different. As long as everything stays normal, they don’t do any shocking – when they detect a dangerously fast heart beat, however, they respond by delivering a massive jolt of electricity to the heart. While this may save the patient’s life, it’s also very traumatic and painful. Now, a team of scientists from Washington University in St. Louis may have come up with a solution to that problem.  Read More

Researchers at Stanford University have developed a new algorithm suitable for brain-implantable prosthetic systems, or “neuroprosthetics,” which increases the effectiveness of mind-controlled computer cursor movement to a degree that approaches the speed, accuracy and natural movement offered by a real arm.  Read More

The biocompatible cryogel rapidly regains its original memorized shape, size, and volume u...

Biocompatible scaffolds, like those developed to stimulate the repair of heart tissue and bone and cartilage in the body, would normally need to be implanted surgically. Now bioengineers at Harvard University have developed a compressible bioscaffold that can be delivered via a syringe before popping back to its original shape inside the body. The material is also able to be loaded up with drugs or living cells that are gradually released as the material breaks down.  Read More

The new sensor improves monitoring of cerebral pressure, which can lead to dementia

A new moisture-proof sensor has been developed, to monitor cerebral pressure that can lead to dementia. It was created by researchers at the Fraunhofer Institute for Biomedical Engineering IBMT in St. Ingbert in Germany. The sensor, that is similar to pressure sensors used by the auto industry, represents a shift from previous implants that allowed moisture to penetrate and destroy the device.  Read More

An experimental ear-powered chip, with a penny for scale

Our ears work by converting the vibrations of the eardrum into electrochemical signals that can be interpreted by the brain. The current for those signals is supplied by an ion-filled chamber deep within the inner ear – it’s essentially a natural battery. Scientists are now looking at using that battery to power devices that could be implanted in the ear, without affecting the recipient’s hearing.  Read More
