This brain-computer interface allows the individual to control a bionic limb that is not attached to the body, directly with thoughts, to reach and grasp a coffee mug.

Artificial Touch

Brain-Controlled Interface Can Control Bionic Limb

Researchers have discovered a unique method for encoding natural touch sensations of the hand via specific microstimulation patterns in implantable electrodes in the brain. This method will allow individuals with spinal cord injuries not only to control a bionic arm with their brain, but also to feel tactile edges, shapes, curvatures and movements.

Decoding Brainwaves with Ink-Based E-tattoo

Researchers have developed a conductive ink that can be printed directly on the surface of a patient’s head in order to measure their brainwaves. These e-tattoos serve as the sensors for electroencephalography, a medical test that measures the brain’s electrical activity. EEG can help diagnose and monitor brain tumors, sleep disorders and other brain issues.

Researchers showed that a laser beam can sometimes act like a solid object and cast a shadow that is visible to the naked eye. In the picture, the shadow appears as the horizontal line traversing the blue background. (Source: R. A. Abrahao, H. P. N. Morin, J. T. R. Pagé, A. Safari, R. W. Boyd, J. S. Lundeen)
Light Control

The Surprising Shadow of a Laser Beam

Imagine a shadow not cast by a solid object, but by light itself. Scientists have uncovered a way for laser beams to block one another, creating visible shadows and redefining our understanding of optics. This discovery could unlock groundbreaking applications in precision light control.
