White Roofs are cool... Literlly!

There may be way to help stop global warming without saving water, using solar panels, and etc. even though these are great practices to help the earth. Paint your roof white!! The theory isn't proven however is backed U.S. energy secretary Steven Chu and other policy makers.

Huh? HOW!

This result is due to the fact that white roofs reflect some of the heat back to space while on the other hand, black absorbs most of the light like a example, a black sidewalk. You may notice that it's extremely hot in the summer. I've had my experiences :p. If every building was painted white in the earth, the heat would lose it's effect by 1/3 of it's power.

What else about it?

If you paint your roof white, this may also have an impact on you. If you have a white roof, you would end up with a cooler house in the summer :). Now, no more complaining about the heat and the sun. Plus as a result, this could change the amount of fossil fuels, green house gases, and so on. However, it depends on which you use more, heating or cooling. Plus, a variable that may change the cooling is where the city, the density of the roof, and the construction on how the building was made. Not only that, the cooling could be slight due to the white paint darkening and parts of the roof having heating vents and so forth. The world will just have to see and wait on what will happen.

African Child Soldiers...

Child Soldiers in Africa is increasing as time passes. There is a rounded 300,000 kids in Africa who are child soldiers and the number is increasing today... (BBC World Service, Children of Conflict). About 1/3 of the child soldiers are in Africa (The Road back from Soldier back to Child, United Nations). Captured children are "trained" for two months and if they fail to do orders or tried to escape, more likely will that person be killed ( BBC World Service, Children of Conflict). Kids have to stay in hot temperatures that are probably 90˚ degrees or over. As a result they end up with skin diseases and broken back from carrying 50 pound equipment (Shelia Velez, Child Soldiers). Child Soldiers should be stopped due to its child abuse. It's horrible for kids to face this madness. I bet about 1/2 of kids in the United States wouldn't survive a day in the army.

Lose your sleep, you lose it for good...

You can't have all the sleep in the world studies have shown. If you think that sleeping until 10 o'clock on a Saturday will pay up the time you woke up at 5 o'clock, unfortunately it doesn't work that way... Lost sleep can't be made up and you'd end up being dragging yourself out of bed. Studies shown that if you stay up for 24 hours, you'll act like a legally drunk person. The confirmation coming soon...

Looking at sleep:

The researchers put nine young adults in sleep for 5.6 hours every 24 hours. However, they were given a long rest in the weekend as a experiment. Also, eight of those nine young adults were not sleep deprived. The experiment lasted for 3 weeks. The following subjects were given tests to see if they can concentrate and focus. In the given tests, they got worser and worser, day by day. The lack of sleep wore them down and they lost their focus.

The Daylight Theory:

Human's natural tendency is to want to stay up at day and sleep at night. However, this could go away as soon as night comes and the next thing before you know it, they could be staying up untili 12 o' clock. Health workers, truckers, and emergency responders should sleep earlier to prevent a "sleep debt" or else the result wiill end up with a mistake or accident.

Overall:
Basically, you should try to not lose sleep or else you could have a "sleep debt".

Texting is a Pain in the Neck, Studies show

Kids usually text all the time when they're at home, school, and even at bed! However, texting can cause tons of injures like chronic pain problems if you text for a lifetime. It has been shown that people who text a lot, has elbow injuries do to too much thumb texting. The way you type on the computer and text on the phone has similar positions who text. Office workers who uuse the computer often usually come home with back pain or shoulder pain. This could happen if you text for a whole day. To see more about the texting problem, Gold, a professor in the Philadelphia, sent a questionnaire to 138 college students who text. The survey was about how many text messages were sent everyday and if they felt any back pain. After the results came, males seemed to text the most surprisingly. However a variable that could have happened with the survey could have been that Gold didn't ask the time of how long they take on the computer. Gold's research will be shown to the American Public Health Association.

Can the I pod damage your ears?

Teenagers usually use their Ipod when they're on the bus or when they're doing your homework. However, the good part that teens usually love about the Ipod ? You can raise your noise level as high as you want and no one could complain. On the other hand, the result? You could end up having an hearing aid. Studies shown that a usual person should only listen to 100 db or decibel every two hours(altogether) . An average I-pod can get up to 130 db! That's louder than a hairdryer which is 85 db! Let's take a look at Goshom, a scientist and his assistant Kathryn Jade White as they study college students who own any portable music players for more than 3 years. They found out that 55 percent of those college students listened volumes more than 85 db while 26 percent preferred levels at about 70 or 85 db. The rest of those students liked volumes less than 70 db. However, none of those students had any serious hearing problems probably because they didn't have their music players long enough. Nowadays, kids are listening to I pods at younger ages which could affect their hearing problems rapidly if they kept listening at a loud volume until college. Unless you want to have poor hearing, I would be careful of the noise level if I were you.

Flamingo One leg Mystery?

For some time, scientists have been trying to find the story behind the flamingo leg theory. Let's take a look at Mathew Anderson's studies about flamingos. His first theory was that if a flamingo stood on one leg, it would help reduce muscle fatigue. If a flamingo sees or hears a predator coming, it would run faster. So, to see if that theory works they, decided race two flamingos. One that stood on one leg and another flamingo that stood on both legs. However, that theory was out when they saw that the flamingo on both legs ran faster than the one with one leg. That takes out that theory. The second theory they found was that standing on one leg helps make you warmer. The scientists assume that since a flamingo stays in the water for most of the time, they would end up being pretty cold. Just like some other birds, in warm weather, they would stand on both legs. However on cold weather, they would stand on one leg since it helps make it warmer for them. My opinion about this is that the one leg theory is right. I remember when I came out of the pool soaking wet. When I put stood on leg like a flamingo, I felt a little warmer. The scientist will have to research more about the flamingo.
