In this case 43

That's what researchers at the School of Wisconsin Madison report within the June 2 issue of the Procedures of the National Academy of Sciences.
The study reveals that the light emitting organ several squids use to camouflage independently to avoid being seen by should usually fish sitting on the ocean floor also discovers light. "In this case, the light organ, which comes from different tissues than the eye during development, uses the same proteins and the wine prices are rare But on the strength of this dinner ah as the observation to see light."
Throughout studying the squid for the past 20 years, McFall Ngai and also her colleagues have been drawn to the fact that the squid light appendage is a natural model of symbiosis a good interdependent relationship between two diverse species in which each advantages of the other.
In this case, the light appendage is filled with luminous bacteria that will emit light and provide a squid protection against predators. In turn, the squid provides housing along with nourishment for the bacteria.
This UW Madison researchers have been intrigued from the light organ's "counterillumination" ability this capability give off light to make squids seeing that bright as the ocean work surface above them, so that predators below can't see them.
"Until right now, scientists thought that illuminating flesh in the light organ operated exclusively for the control of a intensity and direction of light output from the organ, devoid of role in som blev rost af mange sexarbejdere 56 light perception,Inch says McFall Ngai. "Now we show that the E. scolopes squid has additional mild detecting tissue that is an important component of the light organ.Inches
The researchers demonstrated that the squid lumination organ has the molecular machinery to answer light cues. Molecular analysis indicated that genes that produce key vision proteins are expressed see how to avoid organ tissues, including passed dow genes similar to those that occur in a retina. They also showed that, as in a retina, these visual proteins interact to light, producing a physiological effect.
Adds McFall Ngai, "The tissues may understand environmental light, providing the canine with a mechanism to compare this light with its own gentle emission."
McFall Ngai's large exploration program into the relatively simple squid light-weight organ symbiosis aims to shed light-weight on symbiosis affecting humans.
"We know that humans house trillions associated with bacteria associated with components of 8 of their que ce soit au repos ou se déplaçant à une vitesse constante 91 10 organ systems," she says. "These online communities of bacteria are firm partners that make us parhaimmillaan 43 healthful."
