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.

"Gene identified the prevents stem cells from turning Cancerous"
October 15, 2010 Article Source: Rockefeller University
Link to Article

Summary: Research from Rockefeller University shows that having too many stem cells or cells that have lived too long increase your chance of cancer. Apparently a gene called Sept4 has a protein called ARTS and the lack of the protein can increase your cancer risk. To prove this, they bred some mice that lack the ARTS protein and in doing so, they had about twice as many hemotopoietic stem cells as the mice that had the ARTS protein. the ARTS deprived mice ended up getting spontaneous tumors at twice the rate as the regular mice. ARTS interferes with an inhibitor of apoptosis proteins that causes cells to not be able to kill themselves. Thus having a lot of the ARTS protein allows cells to die on schedule.

Significance: Knowing about the ARTS protein, maybe scientists can reproduce it and help prevent cancer.
