Q1 There is a proverb: Only one who has good thick hair can have the hairdressings; today they substitute hair artificially also; but by both methods the tool to do must be strong enough to use. Male mosquito organs are not strong enough to draw the protein. So they do not and not because they have become aveg and a Rishi. Male mosquitoes feed only on plant juices, such as nectar, to get the sugar they need for energy and survival. As males do not bite, they cannot transmit diseases. Female mosquitoes, on the other hand, need protein from blood for the development of their eggs.Proboscis: In female mosquitoes, this mouth part pierces the skin of a person or animal and sucks out blood. The male's proboscis is not strong enough to pierce the skin, and males do not feed on blood. Both female and male mosquitoes use the proboscis to feed on flower nectar and fruit juices. ii Again it is science; the baby sees the world slowly as tools are grown. Why only Red first is the point: Wavelengths below 400 are too short for human eyes to see. A typical human eye responds to wavelengths between 390 nm and 700 nm. An infant can't focus farther than 8-12 inches away. Since red has the longest wavelength, the colour doesn't scatter easily and can even be seen or detected from a long distance. iii 1. It’s estimated that there are 300 million color blind people in the world!
2. Color blindness is more common than you might think! 1 in 12 men is color blind while only 1 in 200 women have the condition. This means that 95% of the color blind community are men. 98% of those with color blindness have red-green color blindness. 3. Red-green color blindness is passed down through the mother on the X-chromosome. However, there are different ways the “color blindness gene” can show up! Learn more about how color blindness is passed down <https://enchroma.com/blogs/beyond-color/can-women-be-color-blind>. 4. Red-green color blindness is the common name for the two most common types called Deutan and Protan. It is given this name since red and green are the two colors that are typically most difficult to distinguish by color blind individuals with either of these conditions. Learn more about the <https://enchroma.com/pages/types-of-color-blindness>types of color blindness <https://enchroma.com/pages/types-of-color-blindness>. 5. Red-green color blindness is caused by a defect in a person’s light-sensitive cone cells. The green-sensing M cone and the red-sensing L cone’s sensitivities overlap more than they would in a normally-sighted person’s eyes, which creates color confusion across the spectrum. 6. Babies are born color blind! As they grow, their color vision improves and is typically fully developed by the age of 6 months. 7. It’s possible to be color blind in one eye and have normal color vision in the other. This is called unilateral dichromacy and it’s very rare.¹ 8. John Dalton, a scientist, wrote the first paper on color blindness in 1794. He believed his own color blindness was caused by a discoloration in his aqueous humor - learn more about John Dalton <https://enchroma.com/blogs/beyond-color/john-dalton-the-father-of-color-blindness> . 9. On the atoll of Pingelap in the Pacific Ocean, 4.9% of the population has achromatopsia or complete color blindness. In the US, only .0003% of the population has the same condition.² 10. People who are red-green color blind are often surprised to find out that peanut butter is NOT green! 11. The mantis shrimp has 12 types of cone cells, 4 times as many as humans! Scientists aren’t sure why they have such a complex visual system yet, but it is known that the animal can see infrared *and* ultraviolet light. Learn more about marine animals’ color vision in our blog <https://enchroma.com/blogs/beyond-color/marine-color-vision>. 12. Contrary to popular belief, dogs don’t actually see in black and white. They are dichromats, which means they have two types of cone cells, and see in mostly blue and yellow. Their vision is somewhat similar to a color blind human’s color vision. Learn more about our furry friends’ color vision <https://enchroma.com/blogs/beyond-color/are-dogs-color-blind>. 13. Peacocks are known for their colorful plume of feathers that are dazzling to humans. However, what’s most important to peacocks is the number of eye-shaped marks on the ends of the feathers. Peacocks see these ‘eyes’ in ultraviolet light, so the more eyes a male peacock has, the more attractive it is as a mate. 14. EnChroma is the #1 online color vision test used by more than 1 million people worldwide. It is the first test of its kind, designed to identify different types and severity of color blindness. A properly administered color blindness test requires that one not wear filtered lenses or glasses, including EnChroma color blind glasses. Take the color vision test. <https://enchroma.com/pages/test>. 15. The Ishihara color blind test was invented by Dr. Shinobu Ishihara in 1916 while he held a military position in the Japanese Army. The test was originally developed exclusively for use by the Japanese Army, but became more widespread in 1917. Color blindness can cause some unique problems in a color blind person’s life that occur in everyday situations that non-color blind people might take for granted. Here’s a list of just some of the issues it can cause: 16. In Romania, people who are color blind are not allowed to obtain a driver’s license. 17. In some countries, there are barriers to entry in certain professionals for people who are color blind. In England, color blindness may prevent you from becoming a doctor; in the US one cannot get a pilot’s license; and in many parts of the world, it’s difficult to become an electrician.³ 18. Because color blind people have a hard time distinguishing between green and yellow, they often have a hard time knowing when a banana is ripe. Many are accustomed to the bitter taste of an unripe banana! 19. People who are color blind often have trouble cooking meat to the proper temperature. Much of the process relies on monitoring the meat’s color and they cannot distinguish between the shades of cooked and uncooked meat. 20. To the normally sighted person, a rainbow features all the colors of the rainbow. For many color blind people, however, a rainbow only appears to have 2 or 3 colors: blue and yellow. 21. To a color blind person, the green light on a stoplight may appear white or even blue, while the red and yellow lights may look similar to each other. 22. Many color blind people struggle to match their black and blue socks and can find themselves a little mismatched from time to time. Read more about what color blind people see <https://enchroma.com/blogs/beyond-color/how-color-blind-see>. 23. Another interesting fact about color blindness is that some of your favorite celebrities may be color blind! There are many public figures with color blindness, here’s a list of a few: - Robert Redford - American actor - Sting - British musician - George Clinton - American musician - Jack Nicklaus - American professional golfer - Howie Mandel - American entertainer - Eddie Redmayne - British actor - Prince William - Prince of England, Duke of Cambridge - Meat Loaf - American musician - Mark Zuckerberg - Facebook CEO and founder - Christopher Nolan - English director - Fred Rogers - American television actor, host of Mr. Rogers - Bing Crosby - American musician - Chris Rogers - Australian cricketer 24. EnChroma color blind glasses were invented by EnChroma co-founder, Don McPherson - Bill Clinton - Christopher Nolan - Eddie Redmayne - Howie Mandel - Keanu Reeves - Mark Zuckerberg - Prince William Windsor - Neil Harbisson - Daniel Arsham - Loren Long - Logan Paul - Fgteev Duddy - CaptainPuffy - Paul Hollywood - Awesamdude - Biffle - Karl Jacobs VI Whatever your age, your body is many years younger. In fact, even if you're middle aged, most of you may be just 10 years old or less. This heartening truth, which arises from the fact that most of the body's tissues are under constant renewal, has been underlined by a novel method of estimating the age of human cells. Its inventor, Jonas Frisen, believes the average age of all the cells in an adult's body may turn out to be as young as 7 to 10 years. But Dr. Frisen, a stem cell biologist at the Karolinska Institute in Stockholm, has also discovered a fact that explains why people behave their birth age, not the physical age of their cells: a few of the body's cell types endure from birth to death without renewal, and this special minority includes some or all of the cells of the cerebral cortex. It was a dispute over whether the cortex ever makes any new cells that got Dr. Frisen looking for a new way of figuring out how old human cells really are. Existing techniques depend on tagging DNA with chemicals but are far from perfect. Wondering if some natural tag might already be in place, Dr. Frisen recalled that the nuclear weapons tested above ground until 1963 had injected a pulse of radioactive carbon-14 into the atmosphere. Breathed in by plants worldwide and eaten by animals and people, the carbon-14 gets incorporated into the DNA of cells each time the cell divides and the DNA is duplicated. Most molecules in a cell are constantly being replaced but the DNA is not. All the carbon-14 in a cell's DNA is acquired on the cell's birth date, the day its parent cell divided. Hence the extent of carbon-14 enrichment could be used to figure out the cell's age, Dr. Frisen surmised. In practice, the method has to be performed on tissues, not individual cells, because not enough carbon-14 gets into any single cell to signal its age. Dr. Frisen then worked out a scale for converting carbon-14 enrichment into calendar dates by measuring the carbon-14 incorporated into individual tree rings in Swedish pine trees. Having validated the method with various tests, he and his colleagues have reported in the July 15 issue of Cell the results of their first tests with a few body tissues. Cells from the muscles of the ribs, taken from people in their late 30's, have an average age of 15.1 years, they say. The epithelial cells that line the surface of the gut have a rough life and are known by other methods to last only five days. Ignoring these surface cells, the average age of those in the main body of the gut is 15.9 years, Dr. Frisen found. The Karolinska team then turned to the brain, the renewal of whose cells has been a matter of much contention. Prevailing belief, by and large, is that the brain does not generate new neurons after its structure is complete, except in two specific regions, the olfactory bulb that mediates the sense of smell, and the hippocampus where initial memories of faces and places are laid down. This consensus view was challenged a few years ago by Elizabeth Gould of Princeton, who reported finding new neurons in the cerebral cortex, along with the elegant idea that each day's memories might be recorded in the neurons generated that day. Dr. Frisen's method will enable all regions of the brain to be dated to see if any new neurons are generated. So far he has tested only cells from the visual cortex. He finds these are exactly the same age as the individual, showing that new neurons are not generated after birth in this region of the cerebral cortex, or at least not in significant numbers. Cells of the cerebellum are slightly younger than those of the cortex, which fits with the idea that the cerebellum continues developing after birth. Another contentious issue is whether the heart generates new muscle cells after birth. The conventional view that it does not has recently been challenged by Dr. Piero Anversa of the New York Medical College in Valhalla. Dr. Frisen has found the heart as a whole is generating new cells but he has not yet measured the turnover rate of the heart's muscle cells. Although people may think of their body as a fairly permanent structure, most of it is in a state of constant flux as old cells are discarded and new ones generated in their place. Each kind of tissue has its own turnover time, depending in part on the workload endured by its cells. The cells lining the stomach, as mentioned, last only five days. The red blood cells, bruised and battered after traveling nearly 1,000 miles through the maze of the body's circulatory system, last only 120 days or so on average before being dispatched to their graveyard in the spleen. The epidermis, or surface layer of the skin, is recycled every two weeks or so. The reason for the quick replacement is that "This is the body's saran wrap, and it can be easily damaged by scratching, solvents, wear and tear," says Elaine Fuchs, an expert on the skin's stem cells at Rockefeller University.
