Welcome!!!!!

Biology in the News is presented by Dr. Lamar's Biology A/B classes. Each student is responsible for posting ONE blog entry and commenting on ONE post submitted by a fellow student.

About your initial posting . . . . . (approximately 150- 300 words)

Your initial posting is worth 30 points. It must be submitted by October 15th. - Locate an electronic article about a new finding in biology. Article must be been written in the last 12 months. Your posting should include 1) the name of the article (3 point), 2) article source - be specific (3 point), 3) date of article (2 point), 4) link to article (2 points), 5) summary of article in your own words (0-10 points), and 6) significance of article (0-10 points). Comments on significance of article can include (but not be limited to) importance of article to self, to society, or to the further advancement of a particular area of biology.

NOTE: To add link, select text in post that you want to link, click on link icon above posting field, and then paste URL information into appropriate field.

About your comments to a fellow classmate's posting . . . . (approximately 100 - 200 words)

Your comments to another student's posting is worth 20 points. Comments must be submitted between October 16 and November 19 - "The more you know, the more you realize there's a lot more to know" is certainly true to science. Read our Biology in the News blob posts. Pick one post (not your own) and submit comments about this post. Comments should included 1) A question that is raised in your mind by the post. The question should have scientific relevance (0 - 5 points) 2) a response to your question. (0-15 points) Research your question and answer it. If the answer is currently unknown, provide additional background information, describe research that is being done in this field, and/or research that is required for the question to be answered.

Researcher's Creat Experimental Vaccine for Alzheimer's

The article “Researchers Create Experimental Vaccine for Alzheimer’s” was posted on Sciencedaily.com on October, 8th, 2010. The article explains that there is another vaccine being worked on for individuals with Alzheimer’s other than the traditional DNA vaccine that is now developed and given out. The Alzheimer’s disease developed form a protein called “beta- amyloid” that attaches to the brain and forms plaque on it and blocks nutrients and messages from reaching the brain. Scientists and students at UT Southwestern have been working on the nontraditional DNA vaccine (Experimental Vaccine) for quit sometime but have yet to perfect it to where it is testable on humans.

The traditional DNA vaccine is a whole injection of “beta-amyloid” right into the arm. This traditional vaccine is no longer beneficial to patients because this vaccine has been linked to having a major side effect, brain swelling. The nontraditional DNA vaccine is just a piece of the “beta-amyloid” gene so the injection is not as overwhelming for the brain at point of injection. The experimental vaccine is being tested on animals. The process is, the animals get a small golden bead with the “beta-amyloid” gene in it injected into their ear and then are watched closely for a long period of time. The students and professors at UT Southwestern will now keep a close eye on the animals for seven years’ time to study the long term effects of the animal’s brain functions.

The significance of this article in to show that there is still hope in science today, that many vaccines are still being advanced and made better. This article will make it known that there is still research going on, and other scientist may become aware and share their knowledge about this topic, or lend a helping hand in the project.

  1. I believe that this article is very significant and a great hope for people with Alzheimers. I would like to know why the new "cure" for Alzheimers is making the brain swell? I believe that is something we should find out before we can actually find the cure. Alzheimers is a verys serious and fatal illness and hurts many families, friends, and people in general. I knew that Alzheimers made people lose their memory, b but I never knew that it was from a protein latching onto the brain and formed plaqe and made it difficult for nutrients and messages from entering. I know that It is the only way to test experiments sometimes, but I wish there was some way to test them on something other then animals; however, i know that seems close to impossible. I believe they should observe the animals for more then 7 years because in my opinion Alzheimers gets worse with age. I really hope that they do find a cure and continue to use science to help people because there are a lot of people out there in desperate need of these vacines.
