Silk Structure Analysis Could Lead to Even Stronger Synthetic Materials

This article, titled, "Silk Structure Analysis Explains Paradox of Super-Strength; Could Lead to Even Stronger Synthetic Materials" discusses an aspect of research into materials science. In our quest to find new materials, it is interesting to find that nature often far exceeds our intellectual abilities.

For this project you are to read the article and write a paragraph about it. Paragraphs should be at least three well constructed sentences.

Next you should find another article about one of the following:
1. Other discoveries of materials in nature that we have found useful.
2. Ways we have imitated nature to develop materials.
3. Totally new materials we have made and their uses.
4. Polymers and/or polymer manufacture. (Silk is an organic polymer)

Finally link to that article and write a well constructed 3 sentence paragraph about your article.

Make sure you put your ID and class section on your work. This project is due by midnight Sunday, 4/3. Remember that you need to do either this or the next 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.

New ways of fighting Drug-resistant bacteria

Drug-resistant bacteria kills, even in top hospitals. But now tough infections like staph and anthrax may be in for a surprise. Nobel-winning chemist Kary Mullis, who watched a friend die when powerful antibiotics failed, unveils a radical new cure that shows extraordinary promise.

In the early 1980s, Kary Mullis developed the polymerase chain reaction, an elegant way to make copies of a DNA strand using the enzyme polymerase and some basic DNA "building blocks." The process opened the door to more in-depth study of DNA -- like the Human Genome Project. Mullis shared the 1993 Nobel Prize in Chemistry for developing this technique.

For this project you are to view the video and write a paragraph about it. Paragraphs should be at least three well constructed sentences.

Next you should find any other video on TED.com and view it. Finally write a well constructed 3 sentence paragraph about your video.

TED is a small nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. Since then its scope has become ever broader.
