Summary:
Aging process can be slowed down with supplements derived from gut bacteria in future. Scientists at Baylor College of Medicine and the University of Texas Health Science Center at Houston have identified bacterial genes and compounds that extend the life of and also slow down the progression of tumors and the accumulation of amyloid-beta, a compound associated with Alzheimer's disease, in the laboratory worm C. elegans. Scientists fed C. elegans, a microbe, each individual mutant bacteria and then looked at the worms' life span and observed that nearly 4,000 bacterial genes tested, 29, when deleted, increased the worms' lifespan.
My perspective of the article:
I agree because of the evidence provided and the observations observed in the lab which suggests that it could be a possibility. I think if it can be possible then it will be very useful, especially for women who are obsessed to slow down their aging process. However, it can also have unknown consequences as we are going against nature by slowing down the natural process of aging.
Impact on me:
As a a student, they do affect me as I get to learn about new discoveries and current researches going on in the world. As a citizen, I can predict that it will rise in the consumer's market and it can be used as a beauty technique or in beauty medications. But it can also have negative health impacts that can may be damage the skin tissue and create new diseases. As a professional, the advantage is that it can make people look young, but if so then it can also have side effects as its going against a natural process to sustain artificial beauty.
Improvements or next step:
Next step is to find out the negative aspect of this process and finding out how this longevity is produced. Also what can be controlled in this process. Researching in detail and collecting more data can make this convincing and help us find other applications of this discovery.

Article#2: Where cigarette smoking's damage is done -- down to your DNA
![Picture](/uploads/6/3/5/4/63549491/896620164.jpg)
Summary:
Scientists knew that smoking cigarettes causes DNA damage and lung cancer. They created a method for mapping that DNA damage at high resolution across the genome. Aziz Sancar and his team developed a technique, nucleotide excision repair, for mapping sites on the genome that are undergoing repair following a common type of DNA damage. It will help understand smoking-induced cancer origin, resistance, and prevention. The by-product, Benzo[α]pyrene when enters body, our blood breaks it down, but it yields a compound called benzo[α]pyrene diol epoxide, which is worse as it reacts with DNA, forming a bond at the guanine; thus, genes can no longer make proper proteins and DNA can't be duplicated.
My perspective of the article:
I support this idea as it can help save lives and understand how smoking can effect DNA which has all of our biological information. This will help develop therapies and other treatment to resolve smoking related health problems. Thus, its very useful to the medical field.
Impact on me:
As a citizen, the impact on me is that I will prevent smoking and I will promote campaigns for stopping smoking, especially in public spaces, so people don't get harmed by second hand smoke. As a student, I got to learn how smoking can have a negative impact on the DNA and it makes me curious to research on and find out more about this topic. It makes me wonder how other diseases like smoking can have an effect on human DNA. As a professional, more research needs to be done on this topic to find out ways to prevent lung cancer by reducing the negative effect of smoking on DNA and reduce the damage.
Improvements or next step:
Next step is to discover how this damage can be repaired or prevented. Discussing with the government to stop or reduce smoking to protect collective health of the society.
