Thought-controlled Computer Cursor

Thought-Controller Computer Cursor Becomes A Reality 

According to a report released on November 19, 2012, researchers led by Indian-origin Scientists have designed the fastest and most accurate mathematical algorithm yet that can help disabled users to move computer cursors with their thoughts. The path breaking recherche was led by Krishna Shenoy of Stanford University, USA. 

The algorithm's speed, accuracy and natural movement closely match those of a real arm. They researchers developed the algorithm form brain-implantable prosthetic systems, known as REFIT, which vastly improves the speed and accuracy of neural prosthetic that control's computer cursors.

The system relies on sensor implanted into the brain, which record's "action potentials" in neural activity form an array of electrode sensors and sends data to a computer. In demonstrations with rhesus monkeys, cursors controlled by the new algorithm doubled the performance of the monkey's actual arm in controlling the cursor. 

Plastic Skin

First Self-healing, Touch-sensitive Plastic Skin Developed 

A Study published in the journal Nature Nona-technology on November 12, 2012 revealed that researchers have developed the first synthetic skin that is both sensitive to touch and has the ability to heal itself quickly and repeatedly in room temperature. The finding could lead to smarter prosthetic or resilient personal electronics that can repair themselves. It was developed by researchers at Stanford University, USA. 

In the last decade(2000-2012), there have been major advances in synthetic skin, but even the most effective self-healing materials had major drawbacks. Some had to be exposed to high temperatures, making them unsuitable for daily use,. Some others could heal themselves at room temperature  but repairing a cut changed their mechanical or chemical make-up. Most crucially, no self-healing material till now was a good bulk conductor of electricity, an important property. Now, the new plastic skin has remedied all these shortcomings.
