  • 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."

      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.

      People in the past, usually get to the point to eat poisonous food. But how will they know if it's poisonous??? Well once they taste it, they will find the taste very bitter. That would usually tell them that it's toxic.

Yale Scientific Magazine - Does Sugar Really Make Children Hyper? - 0 views

  • Years of oral tradition say yes, but modern science disagrees.

      Parents around the world often say that sugar really causes kids to get hyper but real studies from scientists actually proves that it doesn't. 
  • Science first became interested in the link between sugar and hyperactivity when the Feingold Diet became popular in 1973. Devised by allergist Dr. Benjamin Feingold, it advocated the removal of food additives, such as dyes and artificial flavors, from children’s diets because they might lead to hyperactivity. Although this special diet did not originally mention sugar, sugar became grouped under the category of food additives due to the common belief that it affected behavior.

      Scientists became interested in sugar and how it affects kids just when the diet turned popular in 1973. Allergist Dr Benjamin Feingold has been deciding to do the "removal" of food with color dye and artificial flavors from kids diets because they might get to the point of hyperactivity.
  • Through various experiments over the years, scientists have discovered that no substantial evidence exists to support the claim that sugar causes hyperactivity.

      Even though scientists say that sugar does not cause hyperactivity, they still have no evidence for that.

      But others studies show that sugar might not affect hyper kids, but it may affect behavior 
  • Dr. Wesnes conducted a study in which he found that having a large amount of sugar for breakfast led to a severe deterioration of attention span when compared to having no breakfast or eating whole grain cereal. Dr. Tamborlane, also from Yale, reported that children given sugar had higher levels of adrenaline. A possible explanation for this effect is that since sugar is quickly absorbed into the bloodstream, blood sugar rises quickly, which can lead to higher adrenaline levels and thus symptoms similar to those associated with hyperactivity. Furthermore, children with ADHD also tend to have higher levels of insulin.

      Dr Wesnes found that if a kid has a huge pile of sugar for breakfast it can cause them to not pay attention at anything. But if you have a whole grain breakfast you can be more concentrate more. Also Dr Tamborlane says that kids that eat alot of sugar have "higher levels of adrenaline. Another way to say this is that if you eat a lot of sugar all the sugar is absorbed to the "bloodstream" and blood sugar goes up quickly, that"s why kids can have higher levels of "adrenaline."

Normal Heart

shared by marchand5892 on 31 Oct 14 - No Cached
  • Your heart is a specialised muscle that pumps blood around your body. Blood carries oxygen and nourishment to all parts of your body and carries waste products to several organs, notably your lungs and kidneys to eliminate. Your heart is divided into two pumps which work together. Blood coming back from the organs and tissues of your body enters the right side of your heart which then pumps it to your lungs. Your lungs remove waste carbon dioxide from the blood and recharge it with oxygen. The oxygen-rich blood returning from your lungs enters the left side of your heart, which then pumps it to all parts of your body, including your heart muscle itself. This process ensures that there is always enough oxygen and nourishment for your body to work efficiently.

      Everyone's heart is a special muscle, that "pumps around your body" and pumps blood out." The blood gets pushed and picks up the oxygen and the the blood travels through your body and drops the oxygen for the heart to circulate

How does the clock works

shared by marino5856 on 31 Oct 14 - No Cached
  • 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."
    • marino5856
      marino5856 on 04 Nov 14
       
      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:
  • ...3 more annotations...
  • 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.
    • marino5856
      marino5856 on 04 Nov 14
       
      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:

  • So you ask yourself, what does AM and PM stand for? What are the acronyms for AM and PM? What do the initials a.m. and p.m. mean? Both AM and PM come from Latin. AM stands for Ante Meridiem and PM stands for Post Meridiem. Furthermore, Ante Meridiem means before midday (before Noon), and Post Meridiem means after midday (after noon).

      PM and AM  is a latin name. PM stand for post meridiem (after noon) and AM stands for ante meridiem (Before noon) 
    • marino5856
      marino5856 on 13 Nov 14
       
      But it is easier to remember by AM stands for after midnight and PM pre-midnight or prior to midnight
  • Although not the correct acronym, for easy remembering, you could say that AM stands for After Midnight and PM stands for Pre-Midnight or prior to midnight.

      Sugar can be called beer for some adults because sugar gives the same effect to children that eat or drink a lot of sugar as adults can get the effect from drinking a lot of beer.so in conclusion you could get "drunk" for eating or drinking  lot of sugar because when you eat or drink a lot of sugar you get a tummy ache which then a sugar-rush follows causing you to get "drunk"

  • 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.

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.
    • lobo5879
      lobo5879 on 04 Nov 14
       
      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
  • ...3 more annotations...
  • 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.
    • lobo5879
      lobo5879 on 04 Nov 14
       
      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.
