The 21st century has been a busy year for advances in science and technology. This article explores what the author considers to be the top ten of these.
For this project you are to read the article and write a paragraph about one of the three biology related subjects listed below. Paragraphs should be at least three well constructed sentences.
1. DNA, Genomes, and Stem Cells
8. Vaccines and Emerging Infections
10. The Expanding Understanding of Human Ancestry
Next you should find another article about that topic, link to that article and write a well constructed 3 sentence paragraph about the information contained in your article. These are to be primary source articles and you may not use encyclopedias, like Wikipedia. While Wikipedia is a great resource for information, it relies on other sources for its information. You may use the references section to find the articles that they used to gather the information.
Make sure you put your ID and class section on your work. This project is due by midnight Sunday, 5/2. Remember that you need to do either this or the previous project. If you do both projects one will count for extra credit.
Spelling counts. Please do your project in a word processor and then cut and paste it into the comment box. Sloppy work really doesn't save you time, and it there are glaring spelling errors you will lose credit.
If you have problems, email me at aphsbio at gmail.com. Please tell me exactly what your problem was including any error messages.
The subject I chose to write about was DNA, Genomes, and Stem Cells. This is the number one subject in the article, "Top 10 Sci-Tech Stories Of The Decade ." In this article it shows how the amount of work that went into decoding it was being compared to landing a man on the moon. Also it states how beside humans DNA being decoded, the genomes of dogs, cows, chickens, horses, cats, mice, moths, chimps, mosquitoes, bumble bees, puffer fish and pigs were also decoded.
ReplyDeleteAnother article I found about this topic is "DNA difference between stem cell types found."Click Here This article explains how researchers at the Massachusetts General Hospital Cancer Center and Center for Regenerative Medicine have pipointed key genetic differences between mouse embryonic stem cells (ES cells) and induced pluripotent stem cells (iPS cells. The article tells us that this breakthrough could help to explain the lower efficiency and robustness of iPS cells compared to ES cells.

Throughout the last decade, there had been many outbreaks of diseases and viruses but also, many discoveries on new vaccines to treat these viruses and prevent diseases. There were several outbreaks of SARS in 2003 up to the swine flu epidemic of 2009, all of which infected many people but also helped the development of several new medicines. Also, vaccines for other diseases were developed too, like human papillomavirus vaccines and in late 2009, the very first AIDS vaccine was even approved.
ReplyDeleteThis <a href="http://www.who.int/mediacentre/factsheets/fs289/en/index.html”>page,</a> provided by the World Health Organization (WHO) lists the most recently approved vaccines. It explains newly developed vaccines for four different diseases or viruses, including meningitis A and human papillomavirus. Most of these infections each kill more than 200,000 individuals a year, one of them ranging to two million people. Hopefully, these vaccines can help stop the spread of these diseases and eliminate them completely.

A lot of people look further into their genealogy for their hobby, but scientists are still trying to solve the puzzle about what species us humans came from. On October 2009 after 17 years of thorough research scientists released there findings. Their findings where on the Ardipithecus ramidus and how evidence supported the fact that the Ardipithecus ramidus is one of our (humans) ancestors. Then in 2003 researches found Homo florensis or hobbits, which they found that Homo florensis where a separate lineage from humans today.
ReplyDeleteScientists found that under a thick chunk of Antarctic Ocean ice some life still thrives. These creatures where found six-hundred feet below the surface, where scientists thought that only microbes survived, but where surprised when NASA lowered a camera down there. They found a foot long tentacle which they assumed to belong to a jellyfish and a shrimp-like creature (or a Lyssianasid amphipod, which NASA ice scientist, Robert Bindschadler, called).

ReplyDeleteIn the article Top 10 Sci-Tech Stories of the Decade, the part about Vaccines and Emerging Infections talked about diseases that plagued us over the last 10 years. We had to deal with anthrax scares, SARS, and the Swine Flu (H1N1). Another one that scared everyone, but the article didn’t talk about it, was the Bird or Avian Flu. The article also talked about the vaccines that came about over the last 10 years. These vaccines included HPV for cervical cancer, and a trial version of an AIDS vaccine. Concerns about how good some vaccines are for you also made headlines, scarring some people into not getting vaccinated.
ReplyDeleteI read an article titled WHO Experts to Examine Polio Outbreak in Tajikistan. This article talked about investigating a small outbreak of Polio in Tajikistan. Researchers said that this is the first time polio has been seen in this European region since 2002. They plan to investigate the 7 cases of the disease to find out how and where it got started. They think they can identify the origin through genetic sequencing. The article said that about 87% of Tajikistan’s population has been vaccinated against polio and that the people in remote areas may not have been vaccinated. The WHO plans on holding clinics to vaccinate more children and have notified the border countries of Uzbekistan and Kyrgyzstan to be on the look out for symptoms of polio.

Emerging infections have plagued mankind for centuries, but with the help of vaccines made by scientists we have some chances to beat them. For example the swine flu scare is occuring troughout the world and people are still waiting in line waiting franticly for the H1N1 vaccination. But not all diseases have cures. Scientists are still struggling to find a cure for cancer and AIDS.
ReplyDeleteMalaria is another emerging infection occurring throughout the world and still there’s no cure. Originally people from the health community and scientists everywhere have given up hope of eliminating the spread of malaria, but the National Institute of Allergy and Infectious Diseases have recently been motivated to contain, control, and eliminate the spread of malaria. They will do this by learning their past mistakes and history.
