The Healing Properties of Tears: 7 Good Reasons to Cry Your Eyes Out - Beyond Blue - 0 views

  • 1. Tears help us see. Starting with the most basic function of tears, they enable us to see. Literally. Tears not only lubricate our eyeballs and eyelids, they also prevent dehydration of our various mucous membranes. No lubrication, no eyesight. Writes Bergman: “Without tears, life would be drastically different for humans–in the short run enormously uncomfortable, and in the long run eyesight would be blocked out altogether.”
  • 2. Tears kill bacteria. No need for Clorox wipes. We’ve got tears! Our own antibacterial and antiviral agent working for us, fighting off all the germs we pick up on community computers, shopping carts, public sinks, and all those places the nasty little guys make their homes and procreate. Tears contain lysozyme, a fluid that the germ-a-phobic dreams about in her sleep, because it can kill 90 to 95 percent of all bacteria in just five to 10 minutes! Which translates, I’m guessing, to three months’ worth of colds and stomach viruses.
  • 3. Tears remove toxins. Biochemist William Frey, who has been researching tears for as long as I’ve been searching for sanity, found in one

  • study that emotional tears–those formed in distress or grief–contained more toxic byproducts than tears of irritation (think onion peeling). Are tears toxic then? No! They actually remove toxins from our body that build up courtesy of stress. They are like a natural therapy or massage session, but they cost a lot less!
  • 4. Crying can elevate mood. Do you know what your manganese level is? No, neither do I. But chances are that you will feel better if it’s lower because overexposure to manganese can cause bad stuff: anxiety, nervousness, irritability, fatigue, aggression, emotional disturbance and the rest of the feelings that live inside my happy head rent-free. The act of crying can lower a person’s manganese level. And just like with the toxins I mentioned in my last point, emotional tears contain 24 percent higher albumin protein concentration–responsible for transporting many small molecules (which has to be a good thing, right?)–than irritation tears.
  • 5. Crying lowers stress. Tears really are like perspiration in that exercising and crying both relieve stress. For real. In his article, Bergman explains that tears remove some of the chemicals built up in the body from stress, like the endorphin leucine-enkaphalin and prolactin, the hormone I overproduce because of my pituitary tumor that affects my mood and stress tolerance. The opposite is true too. Bergman writes, “Suppressing tears increases stress levels, and contributes to diseases aggravated by stress, such as high blood pressure, heart problems, and peptic ulcers.
  • 6. Tears build community. In her “Science Digest” article, writer Ashley Montagu argued that crying not only contributes to good health, but it also builds community. I know what you’re thinking: “Well, yeah, but not the right kind of community. I mean, I might ask the woman bawling her eyes out behind me in church what’s wrong or if I can help her, but I’m certainly not going to invite her to dinner.” I beg to differ. As a prolific crier, especially on video, I always come away astounded by the comments … the resounding support of people I know all that well, and the level of intimacy exchanged among them. Read for yourselves some of the comments on both my self-esteem video and my recent death and dying video and you’ll appreciate my point. Tears help communication and foster community.
  • 7. Tears release feelings. Even if you haven’t just been through something traumatic or are severely depressed, the average Jo goes through his day accumulating conflicts and resentments. Sometimes they gather inside the limbic system of the brain and in certain corners of the heart. Crying is cathartic. It lets the devils out. Before they wreak all kind of havoc with the nervous and cardiovascular systems. Writes John Bradshaw in his bestseller “Home Coming”: “All these feelings need to be felt. We need to stomp and storm; to sob and cry; to perspire and tremble.” Amen, Brother Bradford!

Gender Focus | The History of Pink for Girls and Blue for Boys - 1 views

  • 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
       
      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?

  • 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”.
    • Nany Rocha
       
      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.

Why Do People Get Bullied - 0 views

  • One of the most common reasons for bullying is image. Anyone who looks the least bit different from what is considered to be normal will likely face bullying at some point in his life. Kids with freckles, acne, moles, buck teeth and other physical differences will be targeted by bullies.
  • Kids who go out of their way to sit in the front of the class, answer the teacher’s questions and do well on exams are also convenient targets because they are considered to be “nerds”.
  • Kids who don’t have the same style of clothing as their peers are often the targets of bullies.
  • ...12 more annotations...
  • Students from families that can’t afford to buy the latest fashions (or even high quality clothes) might endure bullying.
  • Those are are picked on for their lack of trendy clothing will often come home in tears and ask mom and dad, “Why do people get bullied?”.
  • This is a big reason why many parents choose to enroll their kids in private schools that have a strictly enforced dress code.
  • The private school’s required uniform makes life much easier for students from families without the economic means to purchase the latest fashions.
  • . It is usually the kids from wealthier families and neighborhoods that gang up on the kids from poor backgrounds.
  • Kids from wealthy families sometimes look down upon those from lesser means. The media socializes young people to act this way. Having money and possessions is considered to be “cool”.
  • Bullies pick on kids with disabilities because they are considered to be weak and inferior.
  • This is one of the more brutal forms of bullying because children with disabilities are often completely defenseless against aggressors.
  • Even kids with learning disabilities are targeted by bullies for being different.
  • If their fellow students see them getting extra time to complete exams or getting more attention from the teacher, they’ll be viewed as different and be targeted.
  • “four eyes”
  • “geeks”.

Why We're So Materialistic, Even Though It Doesn't Make Us Happy - 0 views

  • We tend to equate buying things with positive emotions. Subsequently, we think that purchasing new stuff makes us happy. It's a pretty clear correlation. In a study published in Neuron, researchers looked at what's going on in the brain when we think about buying stuff. When a product image flashed before people's eyes, an area of the brain called the nucleus accumbens lit up when a subject liked what they saw. Essentially, the brain's pleasure center kicks into gear and floods the brain with dopamine at the very thought of getting something we want. The weirdest thing about this is that just thinking about buying something is pretty much the same as actually buying it.
    • Nany Rocha
       
      We want to buy things,we make our brain think : "the more I buy things the happier I will be,LETS BUY MORE STUFF!"
  • "Thinking about acquisition provides momentary happiness boosts to materialistic people, and because they tend to think about acquisition a lot, such thoughts have the potential to provide frequent mood boosts," Richins wrote, "but the positive emotions associated with acquisition are short-lived. Although materialists still experience positive emotions after making a purchase, these emotions are less intense than before they actually acquire a product."
  • It's probably no surprise to most of us, but study after study shows that buying stuff doesn't make us happy. More importantly, we're actually unhappy when we put too much value on material objects.The big problem here isn't just that we're a little bummed out when someone else has more stuff than we do. It's that when we put a lot of emphasis on materialistic value, we're prone to depression, personality disorders, and more. One study from

Why Do We Change the Clocks Twice a Year? | Wonderopolis - 0 views

  • it’s Daylight Saving Time! Daylight Saving Time (or “Summer Time,” as it’s known in many parts of the world) was created to make better use of the long sunlight hours of the summer. By “springing” clocks forward an hour in March, we move an hour of daylight from the morning to the evening. On the first Sunday in November, we “fall back” and rewind our clocks to return to Standard Time.
    • marino5856
       
      the hour changes to save daylight and light because like we have the sun light we don't need to waste la light. It changes in summer to have more light when it is getting night and in october again so that it is more dark because in winter we don't need so much the light.

"Missing Links" Found between Birds and Dinosaurs - Scientific American - 0 views

  • "Dinosaurs became ever more 'birdy' over time," Brusatte said, but there was no single missing link, he added. Birds and dinosaurs are like two colors in a rainbow, he said — you can recognize each, but they bleed into each other at their borders.
    • jaime5789
       
      Scientists think that dinosaurs and birds were connected, not only because they look alike, but because their blood is identical... 
  • The new pedigree of carnivorous dinosaur evolution is the most comprehensive one ever assembled, the researchers say. The findings show that birdlike features such as wings and feathers developed slowly over tens of millions of years.
    • jaime5789
       
      Dinosaurs evolved to birds, and it happened slowly, it took millions of years for dinosaurs to evolve into birds... Even though they were always changing, they grew feathers, then developed flying skills!
  • The label of "bird" is somewhat arbitrary, but scientists consider the feathered fossil Archaeopteryx to be the first of the group, Brusatte said. "What probably distinguishes birds is the ability to have powered flight," he said, though it's possible that other dinosaurs could fly too.

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.

Why are there 24 hours in a day? › Ask an Expert (ABC Science) - 0 views

  • "The origin of our time system of 24 hours in a day with each hour subdivided into 60 minutes and then 60 seconds is complex and interesting," says Dr Nick Lomb, consultant curator of astronomy, from the Sydney Observatory.
  • Our 24-hour day comes from the ancient Egyptians who divided day-time into 10 hours they measured with devices such as shadow clocks, and added a twilight hour at the beginning and another one at the end of the day-time, says Lomb.
  • "Night-time was divided in 12 hours, based on the observations of stars. The Egyptians had a system of 36 star groups called 'decans' — chosen so that on any night one decan rose 40 minutes after the previous one.
    • marino5856
       
      The 24 hours has been invented by the egyptians. They first divided it into 10 hours but then they divided it in 12 because of the twilight. So night time was divide in 12 hours because they wanted to see the stars in the night and also that there would be light in the day.
  • ...3 more annotations...
  • The subdivision of hours and minutes into 60 comes from the ancient Babylonians who had a predilection for using numbers to the base 60. For example, III II (using slightly different strokes) meant three times 60 plus two or 182.
  • "We have retained from the Babylonians not only hours and minutes divided into 60, but also their division of a circle into 360 parts or degrees," says Lomb.
  • While each country has (in broad terms) historically had distinct measurements for distance, weights etc the method of splitting the day into 24 hours, one hour into 60 mins and one minute into 60 seconds seems to be the only one in use, and indeed to me the only one I know of. This non-metric measurement of time is far from ideal, but what other comparably accurate methods have been used historically?

The Planets in Our Solar System in Order of Size - 0 views

  • What also is amazing is the sheer size difference of planets. While humans think of Earth as a large planet, in reality it is dwarfed by the massive gas giants lurking at the outer edges of our Solar System. This article explores the planets in order of size, with a bit of context as to how they got that way.
    • Diego Hinojosa
       
      Earth can be thought by us people. By a giant planet but in reality it is really little. In our solar system. The biggest planets on the whole solar system are Jupiter and also saturn they both are "gas giants."
  • No human was around 4.5 billion years ago when the Solar System was formed, so what we know about its birth comes from several sources: examining rocks on Earth and other places, looking at other solar systems in formation and doing computer models, among other methods. As more information comes in, some of our theories of the Solar System must change to suit the new evidence.
