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.
October 28 is the 301st day of the year (302nd in leap years) in the Gregorian calendar. There are 64 days remaining until the end of the year.
2013 (MMXIII) was a common year starting on Tuesday (dominical letter F) of the Gregorian calendar, the 2013th year of the Common Era (CE) and Anno Domini (AD) designations, the 13th year of the 3rd millennium, the 13th year of the 21st century, and the 4th year of the 2010s decade.
2013 was designated as:
Structure of the insect compound eye and how insects see
Scientists in the journal Nature reported this week that they have created a tiny compound camera that mimics the perspective of a small insect, with 180 micro-lenses and a 160-degree field of vision.
An experiment to try - you will see how bees and dragonflies see the world with their compound eyes. Bees have 7000 lenses per eye and dragonflies have 29,000. Can you see their food (flowers for bees and insects for dragonflies) and their predators (birds)? The film is meant to show why dragonflies have lots more lenses in their eyes than bees. Any thoughts are welcome.

I've noticed that some of the insects I have taken pictures of seem to have pupils like we do. The pupil is the black hole in the middle of your eye, which allows light to enter. Most insects have compound eyes, so why do some insects, like this dragonfly, seem to have pupils, too? I thought I'd take a closer look...

Album version from Pollard's 2006 album From a Compound Eye
The DTO has been engaged in a major project to create a genuinely whole of government identity solution for Australia. Consistent with the DTOs mission, we started by talking to consumers to work out what their pain points in interactions with identity solutions were. This is what we learned while doing that.

http://www.ophthobook.com A video rich examination of the various eyes in the animal kingdom, and what they can teach us about the human eye. The first half of this lecture discuses the progression of ocular complexity from single-celled organisms through mammalian eyes. The second half discuses alternative eye designs such as mirrors, compound eyes, slit-pupils, and inverted retinas.
Charles Mayo describes the interrelationship of human endeavors and the life patterns of whales within the Stellwagen Bank National Marine Sanctuary. The advent of whale watching, human threats to marine mammals, the formation of the sanctuary, and greater understanding through research in the whales' use of Stellwagen Bank, are an interlocking kaleidoscope of events and factors that affect the area.
Here are songs are from the first 3 solo albums that Pollard would make with producer/multi-instrumentalist Todd Tobias, and there's a marked difference in sound as a result of this collaboration. Fiction Man was composed of songs that didn't make Earthquake Glue, while the double album, From a Compound Eye, was Pollard's first release after the disbanding of Guided by Voices. Normal Happiness came as a result of Pollard writing songs for Steven Soderbergh's movie, Bubble. Side A 1. Gold (0:00) 2. I'm a Strong Lion (3:03) 3. Supernatural Car Lover (4:11) 4.

Subscribe to Munchies here: http://bit.ly/Subscribe-to-MUNCHIES To celebrate marijuana legalization in Colorado, Munchies columnist David Bienenstock recently traveled to Aspen, to attend a legal seminar hosted by the National Organization for the Reform of Marijuana Laws—America's oldest and largest group dedicated to legalizing cannabis. And since the late Hunter S. Thompson was one of NORML's earliest and most consistent supporters, we figured what better way to embrace the sweet smell of herbal liberation in the Rocky Mountain State than by throwing a small victory party at Owl Farm—the author and advocate's home and “fortified compound” in Woody Creek—featuring an appropriately over-the-top pairing of fully legal cannabis and high-end cuisine? Pulling this off required first and for...

Scholl Concepts S20 is an amazing compound and polish all in one. Not to be confused by a tradtional all-in-one (AOI) that includes a wax or sealant as part of the formulation. This 1-step is design to do aggressive compounding and polishing to almost complete perfection. The only time you may need to follow with an additional polish is on a black car for a hyper critical eye. After all is said in done, this product get's Darren's double thumbs up stamp of approval in all areas of performance.
