Mapping Disease

For me who wants to go into the medical field I always find it interesting when an article pops up about diseases. This article begins by telling the reader that they are trying to map a new virus called the H7H9 which is another strain of the bird flu. Mapping of diseases has been around since the 19th century but has been more reactive than proactive. They are trying to map disease on a world scale but cannot seem to get all the data at a local level. They don't have enough information world disease and how they spread which is a cruical way to solve the issue of how to get rid of them. When ranking how effect this is for the mapping of the disease only 7 diseases passed the test of getting a 75 or higher. Among which that didn't pass were HIV and AIDS. It is argued that technology will help further map these diseases. They are trying to use social media to help find discussion of the diseases and where they are located. 
This impacts the world because if we can find out where this diseases are found, how they are being spread, and what causes them we can eventually figure out how to stop them. Prevention of disease like dengue, hay fever, and aids would benefit the world greatly. Mapping them correctly is defintiely a start to the stopping of the spreading of these diseases. 
This is important because if we can better the technology we have and make mapping the diseases easier it will take less time to find out how to prevent the disease from spreading. Fortunately this process is underway and will hopefully be beneficial in the future.

Diversity Defeats Disease

Being a germ freak anything having to do with new discoveries to defeat diseases really interests me which is why I chose this article. In the article it begins by talking about how the diversity of a pond could decrease the risks of amphibians getting effected by this parasitic worm which causes deformalities in it's limbs. Several researchers then describe that this research is some of the best they have ever see on diversity relating to diseases. The researcher  Johnson, started by studying ponds in his local area of California. He would rank the pond on a scale of 1 to 6 on the diversity of the amphibians there and the infected individuals as well. He also calculated the amount of snails who host this pathogen early in life. After three years of dedicated work his results showed that when the diversity of the pond increased the effected amphibians decreased and vise verse. 
The is extremely important in the society we live in today because so many people are effected with viruses and pathogens. If we know that the as the diversity increases the pathogens decrease we could eventually get rid of many viruses that exist today.
The research done here provides a gateway into solving some of the biggest problems that face the extinction of humans, disease. If we know how diversity effects disease maybe this could be the first step in ridding the world of the pathogens that effect us. 



Microbes Thrive in Deepest Ocean

Something about the ocean has always intrigued me, I don't know if it's the vastness of it or the very little knowledge we actually have about it but that's why I chose this article. It begins by described how in a recent study microbes have been found surviving almost 7 miles below sea level in an ocean trench called Challengers Deep. These microbes can metabolize at 1000 times greater pressure than the microbes living on the Earth's surface. Microbes degrade matter and turn them into CO2 which could really impact the ocean in a postive way. They have found it hard to study these microbes because they only live at those extreme conditions so taking them out of their natural habitat causes death for them. Unfortunatley its the scientists only know that these microbes exist, they don't know which ones they are yet, which is crucial in the understanding of how they work and their impact on that environment.
This pertains to the real work because it shows that there is more to life out there than what we already know. For all we know these microbes could be the longest surviving life on the planet and will continue to be long after we are gone. Understanding how these work and what they are can help our knowledge of how the planet we live on works.
It s very important we pay attention to the small things out there. We know that microbes can live on virtually all climates on the planet. Maybe if we understand how they do this we can understand how to prolong the life of humans and the planet.

Human Ancestors?

The study of bones has always intrigued me and any time I find a new discovery in that field of work I immediately have to read it. The article begins by describing the parts of a new skeletal head that was found within the past few years. It teeth and jaws resemble that of not only humans but apes as well. It speaks about this species is not the same as previous ones found like Lucy. The researchers found that the species was not only arboreal, which means climbs trees but also terrestrial. It is shown that this species is primitive due to it's ability to have both. Also the feet bones show that when this species did walk, it had an abnormal gait. Some scientists believe this is a descendant of our ansestors but there is one small problem. This bones date back to a little less than 2 million years old which is after the first known homo species evolved. It is very unlikely for a species to be there, deviate into another, and then back to the same species.Therefore the scientist still have a lot of questions left to answer.

This is important to the world not only to us in the US but our whole species on the Earth. If there were more than one species of homo out there how did we evolve to become what we are today? These findings are important when understanding our evolution but also understanding how to survive the future. If we can find out what happened to these species who were similar it will be much easier to predict the outcome of our species.

Beer Tastes Intoxicating

As a college student reading an article about one of the most popular items on campus seemed intriguing, beer. The article beings by describing the study done that found by tasting one sip of beer, too little to cause intoxication could result in the brain's release in dopamine which is the reward center of a human's brain. The study was done on 49 healthy men and got them to take a sip of beer and Gatorade and observe which of the two effect the dopamine levels. The research shown that one sip of beer creates dopamine to be released making the men actually crave more. The study also shows that men who have a history of alcoholism have increased levels of dopamine released.
This is very relevant to the world because especially in the US we are very much dependent on the consumption of beer. If we understand how the taste of beer can effect the brain we can ultimately solve alcoholism or even prevent the start of it. Knowing that the dopamine levels rise just by the taste of it, people who have histories of alcoholism would know now that it might not even be smart for them to taste beer.
It's important we understand this so we know how alcohol is really effecting us. It was once thought that the only addictive part of alcohol was the intoxication aspect of it but now knowing that it also can be addictive just because of the taste we have the beginnings of how to better manage the use of it.

Microbes Affect Weight Loss

 


After watching many programs on people who have had bypass surgery, I have become more interested in the topic. This article begins by describing how researchers have found that microbes in the the gut formed after bypass surgery lead to more weight loss than the surgery itself. What they did is take the microbes from someone who has had the surgery and implanted them into a mouse who has not had the surgery and the results show a weight loss in the mouse. The article explains how when you diet you are forced to eat less, and your body actually craves more food and tells you to eat more. One way they have reduced the obesity problem is by cutting off a portion of the stomach to make it smaller and therefore you can eat less. This procedure is known as bypass surgery and has sometimes drastic effects. One way they proved that these microbes worked is by taking them out mice who had had the surgery and putting them into normal weight, non surgically enhance mice. Without increasing or decreasing their food intake the mice lost five percent of their body weight just by the microbes alone. The researchers hope is that one day this can be a resourceful way for humans to lose weight with the worries and precautions of surgical procedures.
This would have a very large impact our much overweight society. In the United States especially we have higher rates of obesity, due to the fast and cheap ways to get unhealthy foods. Although not a solution to obesity this would be a start on getting obese people to a healthier life, worry free of diabetes and heart disease. Not having to worry about the effects of surgical procedures would definitely benefit the people who are in dyer need of weight loss.
It's important we understand the microbes work before letting the public get their hands on it. We also need to be aware that this cannot be something taken advantage of. It would not be beneficial if everyone were to say that, "I can gain as much weight as I want because there are pain free and easy ways to take care of this issue" I feel like this should only be used for people who are in desperate need of weight loss and cannot stick to a diet or exercise regime.
