Moderate Alcohol Consumption Lowers the Risk of Metabolic Diseases, Study Suggests
I did my research on this alcohol consumption study and how drinking alcohol may or may not affect the body in a bad way. Because of the increase in obesity worldwide and type 2 diabetes this study was done to see if alcohol consumption helped prevent obesity and type 2 diabetes. The study had over 6000 subjects aged from 35-75. They were tested on different levels from non-drinkers, low alcohol consumption, moderate alcohol consumption and high alcohol consumption. The people in the low alcohol consumption area drank (1-13 drinks a week), medium-to-high-risk (14-34) and very-high-risk (= 35) drinkers. 73% of participants consumed alcohol, 16% were medium-to-high-risk drinkers and 2% very-high risk drinkers. The results showed that low and moderate alcohol consumers were at lower risks for these types of diseases. The results also showed that people in the low to moderate range also had lower blood pressure, lower weight, and lower cholesterol. So in all reality this study shows that drinking is not a bad thing unless done in high consumption.

A burly lineman can sweat through upward of nine pounds of fluid
The article I chose was titled, “How Much Water Weight Can a Player Lose during a Game?” by The Editors from Scientific America, November 11, 2010. The article is on how football players to reach the pro level must be extremely cautious about their health. Meaning they have to eat and drink right. The article then asks “just how much water can players sweat through?” During exercise the body loses moisture through perspiration and respiration this speeds up as the body tries to cool off by sweating. This then evaporates from the skin and taking heat with it and by breathing harder to get oxygen to the muscles.
Trainers subtract a player’s post game weight from his pregame weight to estimate the amount of moisture a player has lost. They try not to let player’s lose more than 3 percent of their overall body weight during a practice session. If a player has lost more than 3 percent of their body weight they would have to rehydrate after that game or practice session. Their intake would be more than the daily water intake recommendations for physically active adults. Fruits and vegetables also provide a source of fluids and make up about a fifth of people’s daily water consumption.
I chose this article because I have went through this playing college football. In high school we never had to weigh or anything of that nature. Once I came to college we had to weigh before practice and after practice. It was a very serious matter also, because if one of my teammates were to not weigh the entire team would have to be punished. Coaches and also trainers told us constantly to get fluids and keep them. By doing this we didn’t have any problems with dehydration.

Family First:Family History Better at Predicting Disease Risk than Screening
Research was led by Dr. Charles Eng to see wither it was better to do family history or a genetic test to predict the risk of cancer for an individual. The Genomic Medicine Institute of the Cleveland Clinic found through research it is better to do a thorough family history then a genomic screening to predict the risk of cancer. Eng said that “Evaluation of family health history still remains to be the gold standard in personal disease risk assessment. The article tells us that genomic screening is not the same as genetic testing. Genomic screening uses portions of a person’s genetic makeup to determine wither there are genetic variants that put people at a higher risk to develop any particular type of diseases. Genetic testing is where people are screened for the presence of an entire gene known to cause a disease. Eng and her colleagues tested 44 people on their risk for developing breast cancer, prostate cancer, and colorectal cancer by using their complete family history and by using a genomic testing tool. The research that was found was that the genomic screening did not identify nine people who were at high risk for colon cancer because of their family history. Doctor’s said that knowing a patient’s family history can determine how a patient will respond to different treatments. Obtaining the information for family history is easy to do and may cost little to no money. One downfall is the time the doctors are put under to conduct this test. Another downfall is that they may not take a thorough enough exam. Dr. Bruce Korf, president of American College of Medical Genetics, said “ There is also potential for misuse and or misinterpretation of results, particularly given the lack of professional counseling that accompanies the results in some cases, and most of the results do not lead to clear actions to modify risk.” Eng stated “personal genomic screening tests could potentially be more effective and accurate if combined with family health history information and used as a complementary tool for cancer risk assessment.” I think that a family health history screening will be better anyway so that you will know more about the situation and how it affected that person who is close to you.

New plant species in Bolivia
Blog assignment
Eight New Species Discovered in Bolivia National Parks
In the Madidi National park and the surrounding areas scientists from the Missouri Botanical Garden and their colleagues discovered eight new plant species. These plant species were found on the slopes of the Andes Mountains in Northern Bolivia. The scientists have been conducting an inventory of all of the plant species in the park. Prestonia leco, Passiflora madidiana, Siphoneugena minima, Siphoneugena glabrata, Hydrocotyle apolobambensis, Weberbauerocereus madidiensis, Styloceras connatum and Meriania horrida are the names of the plant species that were discovered in the park. All eight of these species of plants were given vulnerable status because they are only found in certain places in the park.
For the entire inventory since 2000 the scientists and their colleagues have discovered 132 new plant species, 32 of theses plant species have been published as new species and these eight most recent plant species that were discovered are all in preparation to be published as new species as well. Once these plants get published as new species they will most likely be put under the vulnerable status as well because of their remote location.
The Andes mountains is one place that has the potential for many new plant species to be discovered because of the remoteness of the park and the areas that have yet to be explored. Other areas in the world like Madagascar, the Amazon Jungle, and the Congo Jungle all have the potential for many new species to be discovered. The discovery of these new plants and animals can lead to many great things. Most importantly the discovery of new plants is key because of the potential for cures to diseases and sicknesses that can be rendered from certain plants in the jungles of the world. Plants are the key to the discovery of many new substances and medicines.

Boa Constrictors Can Have Babies Without Mating, New Evidence Shows.
This article discusses a new discovery at North Carolina State University, where a female boa constrictor gave birth to not one but two broods of all female young who were essentially clones of their mother with a rare recessive coloration they obtained from the mom. In other words this female who has reproduced sexually before, switched over and reproduced using parthenogenesis. They know this because snake males have two ZZ chromosomes and females have a Z and a W chromosome. Well these babies were born with two WW chromosomes a combination thought impossible until now. This genome has only been obtained before through complex lab manipulation, but even then they hadn’t been able to do it with snakes just in fish and amphibians. They are unsure why this occurred, stress normally is the trigger for asexual production in species that are capable of it, but this female was under no stress. In fact males were presented too her she just didn’t mate with them, she chose to reproduce by herself. They are unsure of what will happen to these young snakes as they age, they are most interested in how they will reproduce when they get older. Will they reproduce strictly by parthenogenesis or will they do both like their mother? I find this particularly interesting as I have been studying sexual and asexual reproduction in my Biology 315 class. For the most part we have only seen insects that reproduced this way so to see a large mammal reproducing this way is astonishing. Also makes me wonder what percentage of the boa constrictor population is capable of doing this and whether or not it is a recent development? This discovery is obviously going to call for big redo in the way we look at boa constrictor reproduction. Though it is possible that this is just a one of a kind female, it is unlikely that such an ability would work its way into a population at pure random. I think they have been doing things this way for a while we just never noticed it because they don’t do it often. After all if there are suitable males present then why should they reproduce asexually?

Smoke from a Distant Fire
Smoke from a Distant Fire
http://www.sciencenews.org/view/feature/id/64474/title/Smoke_from_a_Distant_Fire
This article is about how large wild land fires can be contained into the stratosphere and then develop into the atmosphere. The smoke is also known to cause dangerous weather and can be carried a long ways before being released. The smoke in the stratosphere were cent to cause random volcanic eruptions and also the smoldering of a fire causes the smoke to release in the stratosphere. The planes that fly over the fires to dump water takes a numerous number of gas to run and the gas is considered to be released into the stratosphere also. Scientist think that smoke causes numerous amount of precipitation and this is what causes thunderstorms. I feel that the smoke heats up the atmosphere while it is being cooled down at the same time but the other clouds are cooling the earth's surface. Also the fuels from the planes flying over causes gases to get into the stratosphere along with the fire's smoke combining together to make terrible weather. The smoke from these fire's build up and flow up stream to the stratosphere but while building up it also pulls in the humid air around it. This then moisturizes the earth's atmosphere and then a random volcanic eruption can occur at any time. I also feel that this article was interesting because it help audience's view how smoke can create bad weather and also create volcanic action in the atmosphere. The why that scientist determined that smoke from fire's causes this action to happened was that these fire's set of different amounts of satellite's. Each satellite had a different reason to go off and the smoke set all the satellites off that were placed by the wild land fire.
