Blurry images…
The ghost imaging technique forms an image by correlating a beam that interacts with the object and a reference beam that does not. Individually, the beams don’t carry any meaningful information about the object. The imaging technique works with visible light, x-rays and other parts of the electromagnetic spectrum and, when the structured light beams…

Moving… Thinking of moving… Standing still!
Brain-computer interfaces (BCI) work on the principle that measurable changes in electrical brain activity occur just by thinking about performing a task. Signals can be read, evaluated, and then converted into control signals via a machine learning system, which can then be used to operate a computer or a prosthesis. In a recently published study,…

Touching. Not-touching. Sensing.
Through the crafty use of magnetic fields, scientists have developed the first electronic sensor that can simultaneously process both touchless and tactile stimuli. Prior attempts have so far failed to combine these functions on a single device due to overlapping signals of the various stimuli. As the sensor is readily applied to the human skin,…

Seeing what cannot be seen…
Identifying geological features in a densely vegetated, steep, and rough terrain can be almost impossible. Imagery like LiDAR can help researchers see through the tree cover, but subtle landforms can often be missed by the human eye. A team of scientists has tapped into the power of machine learning to identify hidden geologic features. Specifically,…

Self-reference. Beauty.
When something pleases us visually – whether it’s a fine piece of artwork, a beautiful feat of architecture, or an untouched natural landscape – new research demonstrates there is a pattern of activity in what’s known as the default mode network (DMN). The DMN is a large-scale system of interacting regions in the brain that…
