Biomedical engineering company Össur has announced the successful development of a thought controlled bionic prosthetic leg. The new technology uses implanted sensors sending wireless signals to the artificial limb’s built-in computer, enabling subconscious, real-time control and faster, more natural responses and movements.
A new study at Newcastle University in the UK has improved our understanding of Type 2 diabetes, providing a new insight into the positive effects that weight loss can have on sufferers. According to the researchers, reversing the condition can be as simple as losing a single gram of fat in the right place.
A research team led by scientists from the University of New South Wales (UNSW) in Australia has studied the mechanism by which connections in the brain are destroyed in the early stages of Alzheimer’s disease. The findings represent another angle of attack in the ongoing battle to find a cure for the widespread degenerative condition.
This is Better than Science Fiction!
A team of University of Toronto researchers has worked through the human genome, switching off genes in an effort to map out those essential in keeping our cells alive. The scientists were able to identify sets of genes associated with specific cancers, paving the way for highly targeted treatments.

Engineers from Princeton University have developed power-generating rubber films that could be used to harness natural body movements such as breathing or walking in order to power electronic devices such as pacemakers or mobile phones. The material, which is composed of ceramic nanoribbons embedded onto silicone rubber sheets, generates electricity when flexed and is highly efficient at converting mechanical energy into electrical energy.
Injecting white blood cells with a special protein transforms them in to ‘super natural killer cells’, that can wipe out cancer, experts have revealed.
The specially engineered cells have the ability to seek out diseased cells in lymph nodes, with one purpose: destroy them.
The breakthrough by biomedical scientists at Cornell University, could stop the disease in its tracks, by preventing it from spreading.
The unique way in which our fingertips can detect changes in both temperature and pressure have been reproduced in an electronic ‘skin’.
In tests, the grooves in the e-skin were able to respond to water droplets running across them and could detect when a human hair was placed on their surface.
The breakthrough could be used to make more life-like prostheses or improve the accuracy of wearable sensors and medical diagnostic devices.

Though sufferers of heart attacks may survive the initial event, they cause permanent damage to the organ in the form of scar tissue, which affects its ability to pump blood. Scientists around the world are working on this problem, with hydrogels, human stem cells and even bioengineered tissue that sticks together like Velcro all offering possible solutions.
