Young Blood May Hold Key to Reversing Aging

Two teams of scientists published their work on Sunday showing that blood from young mice reverses aging in old mice, it makes their muscles and brains younger and stronger. It could lead to treatments for disorders like Alzheimer’s disease and heart disease. Rudolph Tanzi, a professor of neurology at Harvard Medical School, said, “These findings could be a game changer.” Scientists joined old and young mice for a period of five weeks and then examined them. The muscles of the old mice healed about as quickly as those of the young mice, the scientists reported in 2005. In addition, the old mice grew new liver cells at a youthful rate. The experiment indicated that there were compounds in the blood of the young mice that could awaken old stem cells and rejuvenate aging tissue. Amy J. Wagers, a member of Dr. Rando’s team, and an associate professor at Harvard. demonstrated that it could rejuvenate the hearts of old mice. They found that GDF11 revived stem cells in old muscles, making old mice stronger and increasing their endurance. The new blood supply led to the growth of neurons and gave older mice a sharper sense of smell. Scientists hope that it will work on humans too.
This is a revolutionary discovering if it turns out to work on humans. This would affect humans all around the globe and who knows what else it could lead to. If it did work out as planned would it be for the good in the long run though. This is so far away though no one can determine that, but just looking at what they discovered now is absolutely incredible.
This article was very detail oriented, which made it very interesting. Although when stating some findings they used words involving this subject that not the average person would know, only someone with intelligence in this subject would understand what they were talking about and yet they didn’t explain it for the more average readers.

  1. Ryan did a nice job with this review and there are many things that I really liked about it. For example, Ryan did a very good job of picking an interesting topic that draws in the reader. If it was a boring topic, then it wouldn’t be that fun to read at all. Also, Ryan was very descriptive especially when he discussed the study conducted by Harvard Medical School. This allowed for me to paint a clear picture of the study in my mind, which made the review easier to follow. Additionally, I liked how Ryan included a quote in his writing, because this made his point stronger and added validation to it.

    There were only a couple of things that could’ve been better in this review. One thing is that Ryan could have done a better job relating the topic to our lives. What he says about this new discovery changing our lives is a little too vague for me. Also, this is very minor, but it would have been cool if Ryan had included what scientists and researchers are doing now that they have this new knowledge. What I mean is what new areas of exploration have opened up because of these findings.

    Overall this was a well-written and very informative review. I had no idea that younger blood could lead to reverse aging in mice, and this information came as a bit of a shock to me. I can’t wait to see how this discovery affects human lives in the long run.

  3. I think Ryan did a great job with this current event. First, he gave an interesting summary of the article that made me want to find out more about the subject. Also, when connecting the article he read to society, Ryan looked at what this discovery may lead to in the future, rather than just stating how the discovery affects us at the current moment. Finally, Ryan gave a good critique of the article in which he stated his view of the article from the point of view of somebody who was not experienced with the subject of the article. This way, people like me, who also do not know about the subject of the article, know what to expect when they read the article.

    Though Ryan did a great job, there were only a few things that he could do to improve his report. First, some sentences were missing punctuation, which made them confusing to read. Also, Ryan could make his sentences flow better by transitioning from one sentence to the next.

    I found this current events report very interesting. I had never heard about anything like it before reading the article, and I was amazed when I read that younger blood could reverse aging in older organisms. I was also amazed that this has been tested on mice, and it really worked. I think Ryan did a great job with this current event.

  4. Ryan did a good job on this review. He picked an interesting topic that was unknown to people like me. The reader becomes more aware of the infinite possibilities that this discovery has created. Ryan did a thorough job of summarizing the article and explaining the experiment that caused the discovery of how young blood can reverse age in a mouse, while using direct quotes from the article. He also gave an honest critique of the article, so that readers know what to expect, if they decide to read the original article.
    Although his review was well-written, there are a few things that he could improve on to make his next review even stronger. Sentences, such as the last one in the last paragraph, could have better flow and punctuation, so the reader has an easier time figuring out what you are stating. Ryan could have elaborated his statement of how the discovery "would affect humans around the globe".
    Otherwise, Ryan did a great job on his review, and it was difficult to find things that needed to be improved. I never remotely considered that young blood can reverse the aging of an elder. It was amazing to find out. I wonder what scientists are going to do with this new information and improve the lives of the human race.

  5. Ryan did a great job on his review. He not only picked an interesting topic that i was unaware about, but he reviewed the article in depth and understandably. He did a nice job incorperating a direct quote from the article which really enhanced the summary. Lastly, Ryan did a great job with putting lots of important facts in his summary, and did a nice job describing what role different people had in this study.

    Even though Ryan did a great job reviewing this article, there were a few things that could have made it stronger. Some of the sentences were a little confusing to read, so revising a little more would help. Also, Ryan could have his sentences have more flow, so it is easier for the reader to read.

    I would have never though that young blood could reverse the aging of someone older. This was a very interesting topic to learn about, and if it affects mice I wonder how much it can affect the human population. If this could be the cure to treating disorders like alziehmers that would be amazing.

  6. Ryan’s review was great. He picked a fascinating article about how blood from young people can help to reverse the some effects of aging in the elderly. He did a good job of telling how this was discovered with the tests on lab rats and also showed some about how this could be used in the near future.
    A little more about how this could be used could have maybe been helpful. Although some information about this was present it could have just used a little more. There were also some grammatical errors which didn’t really affect the review that much but at times were a bit confusing.
    The article was a great choice and I thought it was fascinating to read. This idea of reversing some of aging’s effects with new blood is incredible.

  7. Well that’s nice to hear that the whole idea of vampires sucking young people’s blood ties into living forever. Great job guys. Now we can become vampires ourselves. Ryan’s review on the original article was a very interesting one. It wasn’t the interesting kind where you actually enjoy it but rather the interesting kind where you see that the information is accurate and impressive. Ryan did an amazing job on discussing the article and providing as much information as possible from the original article. I even like how he added a quote from the original article to tie into his summary.

    Even though his review was well composed there were major areas that he needs to fix. One area is that the paragraphs are not balanced well. The first paragraph is lengthy and the other two are short thus note making the paragraphs balanced. I would instead cut down a couple of words on the first paragraph and put some more ideas into the second and third paragraphs. Another suggestion I give to him is that maybe he should reflect on the article even more. Looking back on the last two paragraphs, his ability to reflect what kind of an impact this has on our society is not as impressive as I thought it would be. If I were to read this article, I would go further into depth in terms of cause and effect.

    Ryan’s article does bring up interesting ideas on how this would effect us in our world today but to be honest, the whole idea is creepy. First, why would anyone want to research this? I mean I know that it would be nice if we could live longer than we are now but if you think about it, this is a bad idea. The article says that it requires the blood of young humans and this is what bugs me. Are we simply going to ask the youth to donate blood for the general well being of another person? Simply outrageous! And who knows how much blood is required before the process kicks in? For all we know as the readers, it could take up a lot of blood, probably even more than what a young person could give if we plan to keep them alive. I don’t mean to be a downer on the idea, I just think that maybe we shouldn’t try it.
