A new scientific study has revealed that people who are simply too scared of steep slopes should move in closer to the edge in order to make their anxiety go away. The conclusion comes from an investigation that showed slopes appeared increasingly mild as you got closer to them. Standing at their very edge makes them... |

With IT enterprises more focused on throwing accusations at one another and with the economical crisis, the IT industry hasn't been doing as well as it should have. Well, the industry itself may be fine, but the marketing side certainly hasn't reached the highest level this year. To somehow improve the sale... |

Scientists from the Lund University Vision Group recently discovered that birds require between 5 and 20 times as much light as the human eye does in order to perceive colors. As a direct result, their color vision decays much earlier in the day than our own, for example. More precisely, the experts determined that, ... |

Robots that can see are nothing new, as they've been around for quite some time now. And we're not talking about machines such as the rover Spirit, which uses its cameras to inform its human operators about what it's doing, but about robots that are able to identify and move around an obstacle all on t... |

It's a widely known fact that the brain, while indeed collecting all the stimuli it sees around us, only presents us with a minor fraction of those stimuli that spring into our conscious mind. When taking this into account, we are, in a sense, partially blind even before a doctor gives the verdict. A new scienti... |

CMOS image sensors are commonly used in special cameras, which provide visual assistance for the visually impaired. But their main disadvantage is that they have relatively poor performances, that they provide only monochrome images, and also that they have a very limited sensitivity to light. A team of experts recen... |

Experts at the University of Washington in Seattle have recently announced the first successful treatment of color blindness using gene therapy, in squirrel monkeys. The method has been applied on animals that were born with the condition, not that developed it over the course of their lifetimes. The new research bri... |

Blindness is arguably one of the things that have the ability to turn someone's life around. The disease carries a huge mental and physical strain on its victim, especially if the patient was not born blind. As such, finding a cure for its developed forms has been a long-standing goal for experts, one that has c... |

Drawing their inspiration from the anatomy and the physiology of the human eye, researchers at the Boston College have devised a new viewing technique that allows computers to see fleeting images, such as butterflies flying and fish swimming very fast. Its accuracy is double, and its speed is ten times that of any ot... |

Acuity is one of the handful of free iPhone apps I've had the pleasure of testing this week. Developed by a company called Intellicore, Acuity is a powerful questionnaire-based application that can accurately tell you whether or not you have good eye sight. Ever had the impression you might have trouble distingu... |

Playing video games may seem like a waste of time to parents, who always seem to be encouraging their children to put down their virtual weapons and go outside to play with their friends. But a new research, published in the journal nature Neuroscience, reveals some unexpected finds that experts have made when analyz... |

It is said that dogs live in a world of scents. Imagine that, in humans, the olfactory mucosa is about 10 square centimeters, and in dogs of 150! Their hearing is also sharper than ours and they detect ultrasounds (the bats' sonar must be a nightmare for them). But this does not mean vision is not important for ... |

There are various types of vision, from the one detecting visible light to the others detecting ultraviolet light and linear polarized light. A new research published in the journal "Current Biology" describes a fourth type of vision never seen before in any animal: mantis shrimps (Stomatopods), a type of sea crustac... |

Your life is made of web chatting, navigation, PC games and the list is endless. Some spend hours and even days without moving from the front of the computer; shower and food are skipped and only physiological needs force them for a few seconds out. But do you think that so much staring at a computer screen does not ... |

This is another investigation that will make women call men as being pigs. But this is the naked truth: men spend about one year of their lives staring at women. And not their women. On average, men look at 11 different women daily (they found them attractive) and each of them receives about two minutes of their atte... |

One day you could say "Hasta la vista, baby!" while zooming in on far-off scenes. Virtual displays could correct vision-impairment, drive holographic control panels and could be even a mean of navigating the Web. A team at the University of Washington could bring to reality this SF technology, operating at microscop... |

Dogs have evolved from wolves. And wolves are nocturnal predators; you can see that very well by analyzing the behavior of stray dog packs. The same dogs that seem very quiet and calm during the day will attack any human passing through their "territory" at night. Indeed, at night or in a forest, eyesight does not he... |

We live in an urban jungle, but lurking dangers differ from those found in nature. Like Stone Age hunter-gatherers, modern people are still more capable of spotting predators and prey, instead of what can really kill us in a city. A new research shows that humans are still much more skilled to observe other people an... |

Humans are not made for traveling during nighttime: around 42% of fatal car crashes happen at night, taking into consideration that at this time there is 60% less traffic. There's little visual acuity and field of vision at night provided by illumination from the headlights. Now a team at the Department of Compu... |

Have you ever wondered why we don't see the world as if it were a movie on a TV screen? Many mammals do have a 2D vision. Nevertheless, from shooting or juggling to baseball or driving, hand-eye coordination requires a three dimensional image of the environment. But it was not known how our brains get the 3D pi... |

Perhaps the aspiration of a not so literate father is to see how his son becomes a great hitter. Well, a new research shows that it is not all about training, but genes too play a role in tracking balls and other moving objects, as revealed by a new research. "Our results show that individuals vary tremendously in th... |

The human eye is one of nature's wonders. An adult eye has about 24 mm (1 inch) in diameter and about 12 million photoreceptors (light sensitive cells) and six muscles that move the ocular sphere with such a precision that it allows the eye to follow moving objects. Like a camera, the eye has a diaphragm (called... |

A new wireless router comes from Belkin, it is called the N1 Vision and it has an interactive network display. As far as I know, this is the only router available on market that dropped the confusing blinking LEDs in favor of a fully fledged display. N1 Vision is packed into a sleek and elegant case and it offers the... |

Have you ever wondered what does a tornado look like form the inside? Unfortunately, the few people who have experienced being inside a tornado or a storm are not happy talking about it. Normally, it would be a bumpy ride and a major death risk, to stare at a storm from inside its eye, and not many volunteers can be... |

You cannot stare at a girl/boy or a painting, because your eyeballs move wildly to get shots of the various traits in the surrounding picture Eyeballs are known to stay still fixing on a spot for 0, 3 - 2 seconds; in between they shake around for up to 50 milliseconds, a moment when vision is stopped, installing a m... |

The bionic eye would be the solution for the vision impaired people in the technology era. But a new research shows that bringing back vision to blind people could completely bypass the eyes. The brain visual cortex was found to understand electric signals received directly from a video device like the visual neurona... |

These efficient killers have not changed since the dinosaur era. They present sophisticated sensory organs yet scientists believed sharks and their relatives, rays (which are nothing more than flattened sharks) are color-blind. Now a team at University of Queensland has revealed that stingrays could be able to see i... |
