A Study to Thwart “Obesity Gene” with Exercise

A Study to Thwart “Obesity Gene” with Exercise

A new study suggests that people predisposed to be obese can reduce their odds of weight

gain by remaining active. The FTO gene or “fat mass and obesity associated” gene has a 27%

weaker effect on physically active adults. Researchers examined the data of 45 previous studies

with more than 218,000 participants.

The main point is that the genetically susceptible can still prevent weight gain with a healthy

lifestyle. Regular activity like walking the dog, taking the stairs, and doing chores still count.

People don’t have to do rigorous exercise for it to help. One hour of activity five times a week

is beneficial.

Some people that are predisposed to being overweight may feel they are hopeless to fight

obesity. A recent study on the effects of genetic testing showed those people increased their

dietary intake over the next three months, suggesting they felt there was no control. However,

researchers feel this sense of fatalism is misplaced.

According to the U.S. Centers for Disease Control and Prevention, 2/3 of American adults are either overweight or obese and nearly 1/5 of children up to age 19. Obesity increases the risk of diabetes,

heart disease, stroke and certain forms of cancer.

Decreasing obesity even when predisposed by the FTO gene would not only be beneficial for

individual health but also for the health care system. Diseases like diabetes and heart disease

cost the health care system millions of dollars each year.

Teen girl students and steriod use.

Characteristics of teen girl students that use steroids
The Center for Disease and Control and Prevention has found that teen girls use steroids for body building, sports and more. Researchers found that in three national surveys indicated an increase of anger in teen girls that use steroids. Young female steroid users were also more likely to:
• have had sexual intercourse before age 13
• have been pregnant
• drink and drive or have ridden with a drinking driver
• carry a weapon
• have been in a fight on school property in the past year
• have feelings of sadness or hopelessness almost every day for at least two weeks
• have attempted suicide
Therefore I believe that this Article will help teens see that steroids if there drugs, or whatever, it can really hurt you. As for me I know that these are all bad for me so I see what else it can do to me.

Peer Pressure on Preschool children

Peer Pressure in Preschool students
Researchers from Max Planck institutes for Evolutionary Anthropology have studied 4 year olds and how there already being peer pressured. In there study, the researchers found that children have made there judjement of something to the judgment of a majority of peers. The researchers did an expirement on a group of preschoolers ,by giving them all a book where 3 had the same and 1 had a different one, the people told the children they were all the same and they believed it. When the children were told something they believed it and dint think one of the books were different and for that point children have been peer pressured even by there peers. From this point I believe many peers will see that they pressure there children, even thought they don’t meen to, and for me now I see how this could be true with peers and start pressure on others.

Teen Suicide Prevention

Teen Suicide prevention
About 1 million people would die by suicide each year. In the U.S nearly 36,000 people take there own lives, and 4,600 victims are between the ages of 10 and 24, making suicide the third leading cause of death in this age group. A Health Care has been researching how to prevent suicide patients that got discharged from going suicidal again, by putting them in a mental health follow up care. After researching on 181 suicidal youths on giving the patients the choice to either do the mental healths follow up or not? 92 percent have gone with the choice of doing the follow up care and have had positive reactions. In knowing that I believe that this health care can help many suicidal patients and bring the suicidal rate down, and as fore me knowing this I know that if I know someone who wants to become suicidal I can tell them to go to this healthcare.

Game Theory

Resource: Science Illustrated May/June 2011

Dreaming. We all do it and we can sometimes remember our dreams, but can we know we are dreaming and control it as well? People can do this, but video games may help us control our dreams much more. Video games have had the effect on dreams. Gamers can know they are dreaming and control them than people who don't play video games often. Even in nightmares, lucid dreaming and dream control may help us in controlling our dreams and stopping constant nightmares. In theory, playing an alternative reality frequently may help us in the reality that lays within our heads. This may even help nightmares to the point they can be entertaining. Both lucidity and dream control are more effective in frequent video game use and may help a certain type of people.

I believe that this is a well done article. It is detailed and gives enough and only enough information to help the reader understand. I think this is a above the average article. I think this may help the people who suffer from traumatic nightmares where the person may actually not suffer or suffer the least amount of fear in dream, so it may help PTSD or anyone who suffers from constant nightmares.

Scared? Got Goose Bumps and Chills?

Resource: Popular Science: November 2011

It is very interesting to how humans get chills and goosebumps. It is also very confusing to why do we do it though. The real reason we get chills and goose bumps is the same reason cats do. If we are going to get attacked, then look as big as you can. This may be confusing especially since we are human beings. This concept had been developed a long time ago when we actually had hair all over our bodies. Someone must have had scared someone away by doing a chill or goose bumps. I imagine this would look much scarier than with hair though. This became a useful defensive mechanism and we do it today naturally. Hair raising happens naturally to the cold since it helps us keep our temperature. However it may happen when we are scared because of that one guy who decided it was a good idea to raise hair. Shivers can also happen to any big surprise or intense emotion. This can even occur in music like when the singer begins to sing or a change in volume. This is another reason why scary movies are popular. False alarms happen to practice our defensive mechanism, so when me watch scary movies, we get the danger, but our conscious still understand were safe.

I enjoyed the article very much. I believe the article gave only a bit of info on the subject, but it said the most important things needed. I believe it was a semi good article for my standards. Also, I believe the more you know may help you, and this article just may interest people into emotions and make people curious.

Erasing Traumas

Resource: Science Illustrated: November/December 2011

This article was very interesting. There are three ways that scientist are learning to stop destroy the fear in a traumatic event. The first type is cognitive therapy. This type of therapy involves reactivating the dreaded memory. After the memory is reactivated, a short window is formed, so the memory can be altered and give a feeling of safety and calm instead. The window comes from an effect from our long term memory retrieval. The memory will not stay the same way it did when we experienced it, but it will instead be a "newer" version since we will alter it. Another type of treatment is a pill. This pill is to be taken before the memory starts. Once the memory activates again, there will be no fear response, and the traumatic part of the memory will dissolve over time. The last and third treatment mentioned were enzymes before the trauma begins. The enzymes break down a protein net around the memories, so it allows the fear induced memory to be erased of the fear by extinction therapy easily. Also, using this before any traumatic events would help forget the fear naturally if something does happen.

I believe this article was made very well. I thought the details and examples given were large parts of why this is such a great article. A well thought out description of the experiments and real life application really impressed me. Also, this could help many of our soldiers that dont deserve to relive terrible moments everyday of their lives. Also, this can altogether possibly stop any root of the problem in any traumatic situation in time. I believe these discoveries and theories could save many people with PTSD.
