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.

Model Unfolds Proteins Gently

Model Unfolds Proteins Gently

Protein molecules reorganize themselves as force is exerted on them. When we do experiments on cells, we normally use greater driving forces. A new model has discovered that protein can be unfolded under gentler conditions. Models that are fast process and consume CPU time. A new, simpler model has the ability to model the slow low-force processes that occur inside the cell. With the use of smaller forces instead of fast, strong forces, researchers have discovered that previously uncharacterized sequential loss of structure involving a fluctuation between two intermediates of similar complexity. This unfolding was shown because of the simpler models. With the smaller forces that we have now discovered, it can lead to a better understanding of biomolecular transitions within the cell

Significance: This is significant because it shows that just because something is more complicated, it is not necessarily more efficient.
