Blind brain. Seeing everything.
Researchers observed slow spontaneous fluctuations in the brain's visual centers that preceded visual hallucinations in blind people. (1) Weird. Even blind people see. At the end, what might be missing is what we all crave for: Not seeing anything... Detached from the cosmos... Only then we might see things that we do not see... And…

“Seeing” blue light…
Plants can perceive and react to light across a wide spectrum. New research shows how plants can respond to blue light in particular by revealing the structure of cryptochrome-2, the molecule that reacts to blue light. (1) "Seeing" blue light. How mundane. Our whole perception enslaved into mere interactions. Our whole thought dictated by things…

Sensitive touch…
To develop a more human-like robotic gripper, it is necessary to provide sensing capabilities to the fingers. However, conventional sensors compromise the mechanical properties of soft robots. Now, scientists have designed a 3D printable soft robotic finger containing a built-in sensor with adjustable stiffness. Their work represents a big step toward safer and more dexterous…

Do you see what I see?
Primates process visual information similar to pixels in a digital camera, using small computing units located in their visual cortex. Scientists of the University of Geneva have investigated whether these computational units scale across the large differences in size between primates. The gray mouse lemur is one of the smallest of them and his visual…

Look. Do you hate war?
New research will allow cameras to recognize colors that the human eye and even ordinary cameras are unable to perceive. The technology makes it possible to image gases and substances such as hydrogen, carbon and sodium, each of which has a unique color in the infrared spectrum, as well as biological compounds that are found…
