Insects exhibit impressive agility and responsiveness even when faced with low-light conditions. The secret lies in their compound eyes, which are capable of detecting motion with incredible speed and ...

A research team has recreated the evolution of the eye in a physics simulation. The results show why nature chose such ...

A camera smaller than a fingernail can now see what most high-speed cameras miss. Inspired by the eyes of insects, scientists have created a tiny, powerful device that captures fast-moving scenes in ...

About five years ago, a bizarre idea occurred to me. At the time, I was designing complex electronic circuits to mimic a small portion of an insect brain. These circuits would be created on a tiny ...

Figure 1. (A) Vision in a fast-eyed insect. Reflected light from swiftly moving objects sequentially stimulates the photoreceptors along the individual optical channels called ommatidia, of which the ...

IN reference to the discussion between Dr. Sydney Hickson and Mr. Benjamin Lowne, I beg to state that I have been favoured by both of those gentlemen with opportunities of carefully studying their ...

In an evolutionary battle of the sexes, male fruit flies have sharpened their eyesight to avoid being tricked by females seeking food gifts while pretending to be fertile. To increase the chance that ...

Conventional dental photography technology has had a limitation in using inconvenient tools such as mirrors and cheek retractors. Dentists require basic teeth images from various angles, such as right ...

Most optical instruments use lenses, mirrors or prisms to coax rays of light. This system works all right for microscopes and telescopes but not for the long, flexible probes (gastroscopes and broncho ...

When a man in his mid-50s living in New Delhi, India first noticed some mild irritation in his right eye, he figured it would pass. But after it persisted for ten days, he thought back to an unlucky ...
