Brain worm in humans tan tan!

shared by CLudio Villarreal on 31 Oct 14 - Cached
  • Cysticercosis is a tissue infection caused by the pork tapeworm (Taenia solium).[1] People may have little or no symptoms for years, develop approximately one to two centimeter painless solid bumps in the skin and muscles, or have neurological symptoms if the brain is affected.[1][2] After months or years these bumps can become painful and swollen then resolve.[2] When cysts form in the brain it is known as neurocysticercosis.[3] In the developing world this is one of the most common cause of seizures.[2]
  • The disease is usually spread by eating foods or water that contains the tapeworm's eggs.[1] The foods most commonly believed to be the cause are uncooked vegetables.
  • Taeniasis is due to eating cysts in poorly cooked pork.

  • Preventing the infection involves: cooking pork well, proper toilets and improved access to clean water.
  • In some cases, cysticerci may be found in the globe, extraocular muscles, and subconjunctiva. Depending on the location, they may cause visual difficulties that fluctuate with eye position, retinal edema, hemorrhage, a decreased vision or even a visual loss.[7][12]
  • Subcutaneous cysts are in the form of firm, mobile nodules, occurring mainly on the trunk and extremities.[13] Subcutaneous
  • Cysticercosis also affects pigs and cows but rarely causes symptoms as most do not live long enough.[1] The disease has occurred in humans throughout history.[5]
  • nodules are sometimes painfu
  • Cysticerci can develop in any voluntary muscle in humans.[7] Invasion of muscle by cysticerci can cause myositis, with fever, eosinophilia, and muscular pseudohypertrophy, which initiate with muscle swelling and later progress to atrophy and fibrosis.[7] In most cases, it is asymptomatic since the cysticerci die and become calcified.
  • The term neurocysticercosis is generally accepted to refer to cysts in the parenchyma of the brain. It presents with seizures and, less commonly, headaches.[8] Cysticerca in brain parenchyma are usually 5–20 mm in diameter. In subarachnoid space and fissures, lesions may be as large as 6 cm in diameter and lobulated.

      Cysticerosis is a disease in the brain tissue that is caused by the pork tapeworm.Some people have few symptoms and some may have many for various years.People get little bumps on the skin and muscle, or you could have neurological symptoms if the brain is affected by the worm.After the years the bumps become painful and after some time they resolve.A cluster of cells then form in the brain, and that is one of the most common cause of surgeries in the world of today.The desiase is usually spread by vegetables that contain the tapeworms eggs, although it is believed that the most common cause of disease are eating uncooked vegetables.

      There is a vaccine for pigs to try and remove Cystisercosis. These vaccines prove to be very effective, these treatments can completely destroy cysticercosis. The cure is developing but can you imagine injecting all the pigs in the world? That would require a lot of money and it would be far grater challenge finding all the pigs in the world.

  • On Aug. 3, 1492, Columbus sailed from Palos, Spain, with three small ships, the Santa María, commanded by Columbus himself, the Pinta under Martín Pinzón, and the Niña under Vicente Yáñez Pinzón. After halting at the Canary Islands, he sailed due west from Sept. 6 until Oct. 7, when he changed his course to the southwest. On Oct. 10 a small mutiny was quelled, and on Oct. 12 he landed on a small island (Watling Island; see San Salvador) in the Bahamas. He took possession for Spain and, with impressed natives aboard, discovered other islands in the neighborhood. On Oct. 27 he sighted Cuba and on Dec. 5 reached Hispaniola.

This Is How Cats See the World | WIRED - 0 views

  • For starters, cats’ visual fields are broader than ours, spanning roughly 200 degrees instead of 180 degrees, and their visual acuity isn’t as good. So, the things humans can sharply resolve at distances of 100-200 feet look blurry to cats, which can see these objects at distances of up to 20 feet. That might not sound so great, but there’s a trade-off: Because of the various photoreceptors parked in cats’ retinas, they kick our asses at seeing in dim light. Instead of the color-resolving, detail-loving cone cells that populate the center of human retinas, cats (and dogs) have many more rod cells, which excel in dim light and are responsible for night-vision capability. The rod cells also refresh more quickly, which lets cats pick up very rapid movements — like, for example, the quickly shifting path a marauding laser dot might trace. Lastly, cats see colors differently than we do, which is why the cat-versions of these images look less vibrant than the people-versions. Scientists used to think cats were dichromats — able to only see two colors — but they’re not, exactly. While feline photoreceptors are most sensitive to wavelengths in the blue-violet and greenish-yellow ranges, it appears they might be able to see a little bit of green as well. In other words, cats are mostly red-green color blind, as are many of us, with a little bit of green creeping in.

  • you cannot derive a polar bear of its cold climate because they are animals who have adapted to their surroundings.

Stanford research: The meaningful life is a road worth traveling - 2 views

happiness meaning research

shared by Nany Rocha on 06 Nov 14 - No Cached
  • One can find meaning in life and be unhappy at the same time. Aaker points out that this type of life has received less attention in the media, which has recently focused on how to cultivate the happy life.  Examples of highly meaningful, but not necessarily happy, lives may include nursing, social work or even activism. The unhappy but meaningful life involves difficult undertakings and can be characterized by stress, struggle and challenges. However, while sometimes unhappy in the moment, these people – connected to a larger sense of purpose and value – make positive contributions to society. Happiness without meaning is characterized by a relatively shallow and often self-oriented life, in which things go well, needs and desires are easily satisfied, and difficult or taxing entanglements are avoided, the report noted. And so, the meaningful life guides actions from the past through the present to the future, giving one a sense of direction. It offers ways to value good and bad alike, and gives us justifications for our aspirations. From achieving our goals to regarding ourselves in a positive light, a life of meaningfulness is considerably different than mere happiness. "People have strong inner desires that shape their lives with purpose and focus – qualities that ultimately make for a uniquely human experience," said Aaker.

      Happiness is also known as a goal of life.It represents us as who we are. Happiness shows on our face.It makes other people see our pride sometimes other people feel our pride so much that they show their pride,and the happiness influence goes and goes until at some point it stops.nI clearly think that if it wasn't for happiness,pride and making our goals (Not soccer goals) we would still be cavemen and cavewomen because without them we would be terrible we would feel stupid we would feel so dum that not even Benjamin Franklin would've created the light because he probably would've felt stupid. So thats why being happy is important because without happiness we wouldn't have accomplished anything.And look at us now we already went to the moon we made a tv we made a telephone and now we have iphones.it all happened thanks to our 1 and greatest feeling:Happiness.

Because the more you think about it the more you understand that happiness is our path to life.that happiness is our friend happiness is our heart that keeps us alive.Thats why we smile thats why we cry thats why we love laugh and live. Without happiness we would be grumpier than the grumpiest cat.We should think more about being grateful than thinking of what to buy to be happy.

  • The planet is one of the brightest objects in the night sky, and even a small telescope can reveal its multicolored stripes. These stripes are bands of clouds being pushed around the planet by strong east-west winds. Jupiter is a world of complex weather patterns. Its most prominent feature is an orange-red oval called the Great Red Spot. The oval is a storm system that has lasted at least 300 years and is bigger across than Earth and Mars combined.

gender pink blue girls boys

shared by Nany Rocha on 31 Oct 14 - No Cached
  • But did you know that pink hasn’t always been a colour for girls, or blue for boys? In Michael Kimmel’s outstanding Manhood in America: A Cultural History, he points out that clothing wasn’t colour-coded in America until the early twentieth century, before which little boys and girls were dressed pretty much identically. Even when people started pushing for more gender-specific children’s clothing, there was a huge debate over which colour to assign to which gender. It started out with boys wearing pink or red because the colours were seen to indicate strength, while girls wore blue because they were “flighty” like the sky. From a 1918 editorial called “Pink or Blue” cited by Kimmel:
    • Nany Rocha
      Nany Rocha on 04 Nov 14
       
      Michael Kimmel pointed out that color coding wasn't used in the vintage america.In fact little boys and little girls used to dress up the same way.But then people wanted to make little kids use specific colored clothes.It started with boys wearing pink or red stuff because the colors where supposed to symbolize strength,while girls used blue because it was soft and dainty (Delicate).
  • So basically the colours changed based on which colour was seen to denote the strength of boys and delicacy of girls, but the idea that those traits are inborn and inalienable did not. It’s not just clothes: walk through the girls’ section of any Toys R Us and you’ll see shelf after shelf of pink, pink, pink. While little girls enjoy some leeway to play with blue toys, many boys get mocked if they want to play with pink “girls’ toys” and sometimes their parents and relatives start panicking that they might even grow up to be (gasp) gay. The fact that parents worry about the sexuality of their kids at all is crazy enough in itself, but that’s for another time. Back to colour-coding.
  • If you think boys and girls just forget about coding gender based on colour once they hit puberty, you’d be wrong. Maricopa County Sheriff Joe Arpaio made headlines when he started forcing male inmates to wear pink underwear to humiliate them. He says it’s a deterrent to reoffending because inmates don’t want to come back and be forced to wear pink again. How screwed up is it that we’ve given a colour so much meaning in less than 100 years that it would make grown male criminals tremble just to think about wearing it?
  • ...2 more annotations...
  • his is about more than policing convicts, it’s about policing the boundaries of masculinity and reinforcing homophobia. Kimmel states: “Homophobia is more than the irrational fear of homosexuals…[it] is the fear of other men – that other men will unmask us, emasculate us, reveal to us and the world that we do not measure up, are not real men.” The pink and blue shoe keychains might not seem like a big deal, and indeed most people don’t think twice about them. But imagine how much harder it could be for some trans and intersex people to negotiate a restroom ritual like this. Gender-neutral washrooms are a big step towards fixing this issue, but so is realizing that blue-pink colour coding is just the tip of the iceberg of things we use to arbitrarily divide “masculine” from “feminine”.

      Gender stereotypes are something that might not seem important,but actually it is a bit important because it kind of symbolizes what a girl or boy will or would use as clothes or other things.I really think that all this stereotypes are dum because it actually doesn't make sense.

  • Neptune is the smallest of the four giant outer planets. The diameter at its equator is about 30,775 miles (49,528 kilometers), as measured at a level of the atmosphere where the pressure is 1 bar (the pressure at sea level on Earth). This makes it slightly smaller than Uranus but nearly four times as big as Earth. Neptune’s mass is about 1.2 times greater than Uranus’, however, and more than 17 times greater than Earth’s. It is the third most massive planet in the solar system, after Jupiter and Saturn. Like the other outer planets, Neptune has a low density—only about 1.6 times the density of water. However, it is the densest of the four, being roughly 25 percent denser than Uranus.

  • When we sleep, we lose consciousness of ourselves. We do not know what happens to us or even our body. But our subconscious mind still keeps on working. Depending upon our desires, thoughts and events, we see them as dreams. Thus, your mind works in such a way that it fulfils whatever you desire. Sometimes dreams have helped great scientists to make brilliant discoveries. Sometimes, people come to know about their future when they are dreaming. How that happens ? nobody knows. Usually, dreams are pleasant. However, sometimes they may be frightening causing nightmares. But they are only our frightened fears and emotions that take form of pictures. So do not be afraid, there are no monsters lurking there. And finally, the art of daydreaming that we all know. The ultimate way of dreaming with our eyes open: - that is our own dream world where no trespassers are allowed.

  • ARE YOU A SUPERTASTER? To find out, put blue food coloring on your tongue. Blue dye doesn't stick to taste papillae, so if your tongue doesn't get very blue, you're probably a supertaster. The bluer it gets, the greater the chance you are a subtaster. More hot sauce!

      If you want to find out if you're a super taster, then simply put food coloring on you tongue. Let's say you put blue food coloring on you're tongue. Blue coloring does not stick to your papillae so if your tongue doesn't get very blue, then you're a super taster but if your tongue gets very blue the you're a sub taster.
  • People who have a lot of papillae—the bumps on our tongue, most of which house our taste buds—often find flavors overwhelming. They're "supertasters," and as such they add cream to their coffee and order food mild instead of spicy. Subtasters, on the other hand, have low papillae density and prefer their chicken wings "atomic."

      Isabel Herrera on 04 Nov 14
       
      People who have a lot of papillae normally finds flavors to be a little bit to much, that shows that you're a super taster. But when you're a sub taster you have a very low amount of papillae.  
  • Most toxic plants taste bitter, and nomadic groups that came into contact with a variety of plants would have, over time, developed a variety of receptors. People from malaria-infested parts of the world tend to carry a gene that makes them less sensitive to some bitter compounds, specifically those that contain cyanide.

  • Saturn was named after the ancient Roman god of agriculture. His counterpart in ancient Greek mythology was Cronus, the father of Zeus (the counterpart of the Roman god Jupiter). The planet Jupiter is Saturn’s nearest neighbor and the closest to it in size and composition. Like Jupiter, Saturn is a giant world formed mainly of hydrogen with no solid surface. It has a massive atmosphere, or surrounding layer of gases, with complex weather patterns. ESA/NASA/JPL/University of ArizonaESA/NASA/JPL/University of Arizona The planet’s extensive system of icy moons includes nine major moons and dozens of small ones. Some of the moons help create the rings and maintain their shape. Titan, the largest of Saturn’s moons, is bigger than the planet Mercury.

  • A day consists of two 12-hour periods, for a total of 24 hours. An hour consists of 60 minutes. A minute consists of 60 seconds. Seconds are subdivided on a decimal system into things like "hundredths of a second" or "millionths of a second."

      There is 24 hours in a day because  they first divided 60 and that equals 12. So 12 plus 12 equals 24 so thats how they had 24 hours in a day.
  • hat's a pretty bizarre way to divide a day up. We divide it in half, then divide the halves by twelfths, then divide the twelfths into sixtieths, then divide by 60 again, and then convert to a decimal system for the smallest increments. It's no wonder children have trouble learning how to tell time.
  • How long is a day? It's the amount of time it takes for the Earth to rotate one time on its axis. But how long does it take the Earth to rotate? That is where things become completely arbitrary. The world has decided to standardize on the following increments:

  • Why are there 24 hours in a day? No one really knows. However, the tradition goes back a long way. Take, for example, this quote from Encyclopedia Britannica:
  • Why are there 60 minutes in an hour and 60 seconds in a minute? Again, it is unclear. It is known, however, that Egyptians once used a calendar that had 12 30-day months, giving them 360 days. This is believed to be the reason why we now divide circles into 360 degrees. Dividing 360 by 6 gives you 60, and 60 is also a base number in the Babylonian math system.

      The Egyptians had a calendar that has 12 months so that equals 360 day in total. Also science they new that there is 360 days in a year thats why a circle is 360 degrees. The Roman people invented that so that in the clock there is not 24 hours in a clock so there is 12 am and 12pm.
  • What do a.m. and p.m. mean? These abbreviations stand for ante meridiem, before midday, and post meridiem, after midday, and they are a Roman invention. According to Daniel Boorstin in his book The Discoverers, this simple division of the day into two parts was the Romans' first increment of time within a day:
