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, […]

Seeing better. And better. And better. Until we see nothing at all…
A few years ago, a team of scientists at EPFL’s Laboratory of Nanoscale Biology, headed by Aleksandra Radenovic in the School of Engineering, developed an algorithm that can estimate a microscope’s resolution in just a few seconds based on a single image. The algorithm’s result indicates how closely a microscope is operating to its full […]

Colour. And shape…
There are hundreds of thousands of distinct colors and shapes that a person can distinguish visually, but how does the brain process all of this information? Scientists previously believed that the visual system initially encodes shape and color with different sets of neurons and then combines them much later. But a new study from Salk […]

Blind people seeing…
Researchers presented 20 blind and 20 sighted adults with animal names and asked participants to: order animals by size and height; sort animals into groups based on shape, skin texture and color; pick which animal out of a group is unlike the others in shape, and choose from various texture options (“Does a hippo have […]

Colour where there is no colour… A cosmos where there is no cosmos…
Engineers have found that under the right conditions, ordinary clear water droplets on a transparent surface can produce brilliant colors, without the addition of inks or dyes. By tuning size, illumination angle, and curvature, MIT engineers can produce brilliant colors, in patterns they can predict, in otherwise transparent droplets. (1) Under the right angle, everything […]
