How we see better by 'looking away'

When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent ...

Dynamic Vision Sensor tech works like human retina

(Phys.org) —If technology expertise can advance artificial intelligence, what can we imagine for artificial vision? An interesting development in artificial vision comes from a Swiss company iniLabs. They have developed ...

Living in space

Every day, 400 kilometres above our heads, there are astronauts living in space. Their home is the ISS, the frontier outpost of human exploration, and a workplace like nothing on Earth. With spacewalks and dockings to contend ...

First mouse, now human, lab-grown eye tissue

Producing retinal tissue from human embryonic stem cells is now possible thanks to a team of researchers led by Yoshiki Sasai of the RIKEN Center for Developmental Biology in Kobe, Japan.

Scientists see new hope for restoring vision with stem cell help

Human-derived stem cells can spontaneously form the tissue that develops into the part of the eye that allows us to see, according to a study published by Cell Press in the 5th anniversary issue of the journal Cell Stem Cell. ...

Study uncovers clues to what makes anesthetics work

Physicians use inhalation anesthetics in a way that is incredibly safe for patients, but very little is known about the intricacies of how these drugs actually work in children and adults. Now, researchers have uncovered ...

Nanometer-scale growth of cone cells tracked in living human eye

Humans see color thanks to cone cells, specialized light-sensing neurons located in the retina along the inner surface of the eyeball. The actual light-sensing section of these cells is called the outer segment, which is ...
