Air Force Treating Wounds With Lasers and Nanotech

Forget stitches and old-school sutures. The Air Force is funding scientists who are using nano-technology and lasers to seal up wounds at a molecular level.

The process would replace the sutures and staples traditionally used to repair wounded skin. Instead of being sealed up with a needle and thread, a patient’s wound would be coated in a dye, then exposed to green light for 2-3 minutes. The dye absorbs the light and catalyzes molecular bonds between the tissue’s collagen.

The bonds instantly create a seal that’s watertight, which prevents inflammation or risk of infection, and speeds up the formation of scar tissue.

HUMAN PHYSIOLOGY CASE STUDIES presented in Wikipages

Instructions

Create a Wiki account:

Go to http://www.wikispaces.com and create an account for your group. Name the account “Period_RespiratoryCase1” (for example) so we know what case study is being presented. Simply follow the on-screen directions to build your site.

What to include in your Wiki:

The purpose of your Wiki is to educate other students in the class about your case study. You can assume that your audience knows the basics about how the circulatory and respiratory systems work, but you need to clearly explain all of the specific aspects of your case study. Be sure to include:

Text:
1. An introduction to your patient (age, sex, symptoms, whatever history is relevant)
2. An overview of the basic issue/condition/problem faced by your patient
3. A discussion of what’s causing the symptoms, how it’s diagnosed, and how it should
be treated. This part of your Wiki should essentially answer the questions
presented in your case study. Don’t write them out as answers though – present the
information in an interesting, clear way that will share your understanding of the
patient’s condition with your fellow students.
4. Include links to relevant sources used to find your information.

Pictures: Place at least two (but preferably more) figures, diagrams, photos etc. to illustrate your case study. Engage your viewer with interesting images.

Video/animations: Embed at least one video or animation in your wiki, again, illustrating some aspect of your case study. Try to find videos that pack a lot of relevant information into a short amount of time. Use your best judgment to find examples that are accurate and clear. Under EDIT menu go to Widgets and Video. Follow the onscreen directions. Check with your teacher if you aren’t sure.

Teen Begins Ascent of Mt. Everest?

This is the latest report I can find about Californian teen trying to be the youngest person to climb the "Seven Summits" - the highest point on each continent. In the film you watched in class, the climbers have to go up and down the mountain over several weeks, acclimating to the altitude. The teen and his parents are taking an alternate route that doesn't involve this acclimation stage. Hopefully we'll find out soon how he's doing!
