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.

Blog 1

The article “New Key to Tissue Regeneration: Drug Treatment Triggers Sodium Ions to Re-grow Nerves and Muscle” was founded by Science Daily. The article was composed on September 29, 2010. The discusses how sodium ions may not be as bad as everyone thinks they are. Sodium ions may take place in a big development in the regeneration of tissue that has been severely issued.
The articles discusses that sodium ions may be helpful in the “regeneration” of formerly injured cells. Most of us associate sodium with high blood pressure and a bigger issue, cardiovascular disease. Tuft University has found through research that the injection of sodium ions into injured cells may repair the damaged cells, found in the spinal cord and muscle. The injection of small molecules can be injected directly after a severe injury to the tissue(s). This development has broken new ground due to the fact it requires no gene therapy, and can be administered immediately following an injury. It’s neat to note that this new development can even be administered after a wound has healed over. A study was conducted on tadpoles, where their tails were regenerated using these injections. The tails were apparent just after an hour of treatment.
This new development is extremely important to society. Limb loss and spinal cords issues are a medical problem world-wide. With this new development these problems can be solved. I am not a science whiz, I did not and do not understand all the terminology in this article. However, I found this article to be extremely informative and beneficial to society. The link to the article is listed below. The article was very informative, and the studies are findings seem to be phenomenal, check it out!
