  • At the heart of the solar system is our sun. The four planets nearest it are rocky, terrestrial worlds — Mercury, Venus, Earth and Mars. After that are four gas giants — Jupiter, Saturn, Uranus and Neptune. Between the orbits of Mars and Jupiter lies the asteroid belt, which includes the dwarf planet Ceres. Beyond the orbit of Neptune one finds the disk-shaped Kuiper belt, in which dwarf planet Pluto resides, and far beyond that is the giant, spherical Oort Cloud and the teardrop-shaped heliopause. See the structure of the solar system (infographic).

  • If you experience engine trouble, you take your car to a mechanic. If your pipes leak, you call a plumber. And if you fracture a leg, the usual course of action is to visit a doctor. But unlike other things that may break in life, bones begin healing on their own before you even set foot in a waiting room.The human body possesses amazing healing powers that enable it to bounce back from a vast array of illnesses and injuries. Sometimes broken bones can heal so thoroughly within a few months that even an x-ray can't determine the original fracture line.Doctors often play a vital, sometimes lifesaving, role in a bone's healing process. But, these experts basically help the body heal itself. Doctors provide optimal conditions for bone repair and healing to take place. The rest is up to your cells.But how does this amazing biological process work? How can a fractured limb grow back to its former strength? To understand, you first have to take a closer look at just what bones are made of and how alive they really are.

  • 3,600 seconds, now defined in terms of radiation emitted from atoms of the element cesium under specified conditions. The hour was formerly defined as the 24th part of a mean solar day—i.e., of the average period of rotation of the Earth relative to the Sun. The hour of sidereal time, 1/24 of the Earth’s rotation period relative to the stars, was about 10 seconds shorter than the hour of mean solar time.

  • In even earlier systems of timekeeping, an hour was 1/12 of a period of daylight or darkness—hence, variable in length with seasonal changes in the length of day and night. The custom of dividing the cycle of day and night into 24 periods seems to have originated with the ancient Egyptians.

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
  • ...5 more annotations...
  • 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!

Why aren't lakes salty like the ocean? - 0 views

Salty ocean

shared by marino5856 on 04 Dec 14 - No Cached
  • The ocean is salty for several reasons, one of which is the groundwater from rain which trickles down into the ocean and picks up salt from the earth along its way! But this same water trickles down into lakes… so why aren't lakes salty?
  • The reason lake water usually isn't salty (or at least it's less salty than ocean water) is because the salty groundwater not only runs into the lakes, but also back out of it! Unlike the huge, vast ocean which already covers most of the Earth and therefore can't open up to any larger body of water, most lakes have outlets from which water leaves. This means that the salty groundwater has a chance to filter out and escape! (In the ocean, it has nowhere e

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

      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.

  • The ocean is also salty from rainwater that falls onto rocks or land, picks up some salt in the earth, and then trickles down into the ocean! There are also some places in the ocean floor where salty gases and minerals from within the Earth get released into the ocean!

      Scientists think that dinosaurs and birds were connected, not only because they look alike, but because their blood is identical...

      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.

  • All blood enters the right side of the heart through two veins: The superior vena cava (SVC) and the inferior vena cava (IVC) (see figure 3).The SVC collects blood from the upper half of the body. The IVC collects blood from the lower half of the body. Blood leaves the SVC and the IVC and enters the right atrium (RA) (3).When the RA contracts, the blood goes through the tricuspid valve (4) and into the right ventricle (RV) (5). When the RV contracts, blood is pumped through the pulmonary valve (6), into the pulmonary artery (PA) (7) and into the lungs where it picks up oxygen.

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.

      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

  • 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. It is the only moon in the solar system known to have a dense atmosphere.

Five Stages Of Sleep ... Sleep Cycles Explained - 2 views

stages sleep

shared by lobo5879 on 03 Nov 14 - No Cached
  • Stage 1This is the lightest stage of sleep, the transition phase, where you feel yourself drifting off. If you were to forget about the alarm clock and allow yourself to wake up naturally, Stage 1 sleep would be the last stage before you fully wake up. You don't spend too much time in Stage 1 sleep, typically five to 10 minutes, just enough to allow your body to slow down and your muscles to relax.
    • lobo5879
      lobo5879 on 04 Nov 14
       
      The stage 1 of sleep is when you are starting to relax your muscles and start to sleep. This stages is not very long it is about 5 to ten minutes. This stage is when you wake up more quickly for example if someone touches you you will easily wake up.
  • Stage 2The second stage of sleep is still considered light sleep. Your brain activity starts to slow down, as well as your heart rate and breathing. Your body temperature falls a little and you're beginning to reach a state of total relaxation in preparation for the deeper sleep to come.
  • Stage 3Stage 3 sleep is the start of deep sleep, also known as slow wave sleep. During stage 3, your brain waves are slow "delta waves," although there may still be short bursts of faster of brain activity (also known as beta-waves). If you were to get awakened suddenly during this stage, you would be groggy and confused, and find it difficult to focus at first.

      this stage is when your body is finishing to relax and example is: if someone trys to wake you up you would be confused and do not know what is happening because you were already finishing to completely relax

  • Stage 4Of the five stages of sleep, this is the one when you experience your deepest sleep of the night. Your brain only shows delta-wave (slow wave) activity, and it's difficult to wake someone up when they're in Stage 4 of sleep.

      this stage i when you are more hardly to be awaken. In this stage is when you start to dream and this stage is when the kids start having nightmares
  • It's during Stage 4 sleep that children are most likely to suffer from bedwetting or sleep terrors. Stages 3 and 4 can last anywhere from 5 - 15 minutes each, but the first deep sleep of the night is more likely to be an hour or so. This is the time when the body does most of it's repair work and regeneration.
  • Stage 5 This is the stage of sleep when you dream. It is also referred to as "active sleep" or REM sleep, which stands for the rapid eye movements that characterize Stage 5. During REM sleep, your blood flow, breathing, and brain activity increases. An EEG would show that your brain is about as active as it is when you're awake.Another aspect of Stage 5 sleep is that the muscles in your arms and legs will go through periods of paralysis. Scientists speculate that this may be nature's way of protecting us from acting out our dreams.The first period of REM sleep of the night usually begins about 90 minutes after you start drifting off, and lasts for about 10 minutes. As the night passes, the periods of REM sleep become longer, with the final episode lasting an hour or so.Babies may spend as much as half of the time they're asleep in the REM phase. For a healthy adult, Stage 5 occurs for about 20 to 25% of the time you are sleeping, and decreases with age.Scientists and researchers are continually learning more about the mechanics and physiological effects of sleep, and what happens during the five stages of sleep.
