When Surgery Succeeds, But Healing Fails

Putting Vitamin E on your cuts? Why?

A study out of the University of Miami reinforces other dismissals of Vitamin E's scar-preventing powers.

So how did you hear about Vitamin E? When I was in elementary school, one of my teachers said that seals secreted it into their cuts and that seals never got scars. It's a wonder I made it out alive.

Electrical "switch" found for limb regeneration in amphibians

Hecate submitted, created time 1 year 10 months (www.nature.com)

Researchers at the Forsyth Center for Regenerative and Developmental Biology (Boston, MA), have been able to use electrical currents to stimulate limb regeneration in tadpoles, even older tadpoles that have naturally lost their ability to regenerate on their own. I think this article is excellent for educational purposes. It is a good example of how researchers can search for the cause of a given phenomenon -- like limb regeneration -- by knocking a trait down or out. Here, they looked for factors that would stop limb regeneration but not impede general wound healing.
