Human retinas grown in a dish explain how color vision develops

Several cancers affect only young women with several forms of pancreatic cancer on October 19, 2018, why the pancreas is an organ that is rarely exposed to hormones, but attacks women, usually young people, in particular I will. This pancreatic cancer known as the "mucous cyst" strangely resembles another mucinous cancer affecting the ovary. Through extensive analysis of genome data, researchers offered [...]

Innovation, integration and maintenance to ensure optimal cancer treatment October 19, 2018 To ensure that all patients receive the best cancer treatment, integrate today's scientific progress and transfer them to It can only be achieved by switching to treatment tomorrow. And through clinical efficacy and accurate identification of the most effective patients

Increase in mortality in children with inflammatory bowel disease Children with inflammatory bowel disease (ulcerative colitis or Crohn's disease) reported on October 18, 2010 increased the risk of death surviving after childhood I will. Therefore, the researchers behind this study think that it is important to carefully monitor patients diagnosed as children.

Agents that were first discovered on October 17, 2018 150 years ago and used as smooth muscle relaxants may increase the susceptibility of tumors to radiotherapy. Researchers found that drug papaverine inhibits mitochondrial respiration, mitochondria are oxygen and energy components of cells, and make model tumors sensitive to radiation. They discovered that medicine does not affect radiation [...]

As the cells grew in the laboratory into an intact retina, the team first discovered that cells that detect blue are recognized, then red and green cells are recognized. In both cases, we found that the key to molecular switching is the undulation of the thyroid hormone. Hormonal levels are not controlled by the thyroid gland and the thyroid gland is, of course, not in the culture dish, but is completely controlled by the eye itself. Knowing how the amount of thyroid hormone determines whether the cells turn blue or red and green, they only see the blue, green and red retina if they are part of a perfect human eye No retinas can be made

Human color vision depends on three photosensitive proteins present in our retina called opsin. Each kind of opsin absorbs one color of light in the spectrum. In humans, these opsins absorb the red, green, or blue color. The light of many wavelengths reflected by our eyes from the surface of the object around us intermix and provide a rich color. However, despite our extensive visual color, there is a wider range of organisms, cockroaches are classified as insects in this order (suborder: wilder; different feathers) slowly flying hornets (suborder: Zygoptera; double feathers). Cockroaches are characterized by large, multifaceted, or "false eyes" eyes, two pairs of rugged, transparent wings and thin bodies. Interestingly, even if they have six legs (like other insects) they can not walk.

Because humans have very complex visual abilities, they can perceive color and depth with complex details. Visual stimulation transitions occur in the retina. The photoreceptor cells found in this area have the special ability to convert light or the ability to convert light into electrical signals. There are two types of these photoreceptors. Rod which causes night vision (night vision), cone for clear vision (daytime visibility)
