Eye

Eyes are the organs of vision. They detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex.

Eyes (video game)

Eyes is an arcade game released in 1982 by Rock-Ola.

Gameplay

The player controls a hat-wearing eyeball in a maze. As in Pac-Man the goal is to collect all of the dots to advance to next level, but in Eyes you shoot the dots rather than eat them. Computer-controlled eyes chase and shoot at the player. Shooting a computer eye gives points and removes it from the level, but it will reappear a short time later. Being shot by a computer eye is fatal.

As the game progresses, more computer eyes are added to levels and they take less time to shoot at the player. They also move faster.

Eyes Galaxies

The Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. This galaxy takes its name from its ring structure which made it popular.

NGC 4435

NGC 4435 is a barred lenticular galaxy with a relatively young (age of 190 million years) stellar population on its central regions that has been discovered by the Spitzer Space Telescope and whose origin may be the interaction with NGC 4438. It also has a long tidal tail possibly caused by the interaction with the mentioned galaxy; however other studies suggest that tail is actually a galactic cirrus in the Milky Way totally unrelated to NGC 4435.

NGC 4438

NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy mechanism may be a starburst region, or a black hole powered active galactic nucleus (AGN). Both of the hypotheses are still being investigated.

Kush (band)

Kush was an American rap metal band formed in 2000 by rapper B-Real, Deftones guitarist Stephen Carpenter, and former Fear Factory members Raymond Herrera and Christian Olde Wolbers.

History

The project was first announced in 2000. "Dr. Kush" was chosen as an alternate name in case the original band name was already in use. In November 2000, it was reported that seven tracks had been completed. In 2001, B-Real expressed an interest in releasing the band's debut album by the following year or in 2003. Kush performed at the fifth annual Cypress Hill Smoke Out in 2002, opening with a song entitled "Psycho Killer", one of ten completed tracks that were prepared for an eventual album. B-Real stated that the band's music is "unlike any other rap-metal type stuff. It's a little bit more aggressive. And the way I attack it from a lyrical standpoint is totally different from what I do with Cypress. Cypress is more street-orientated. With Kush, it's a little bit of everything." In April 2002, it was reported that Kush had completed its debut album, but that it would be difficult to release because all of the band members were signed to different labels. In November 2002, it was reported that the album was not completed, but that it was getting close to completion. To date, no material from the band has been released officially, but demos have been leaked on various file sharing sites.
