Scientists Re-grow Dental Enamel

A reader at Cloning Resources writes "Dental enamel is the hardest tissue produced by the body. It cannot regenerate itself, because it is formed by a layer of cells that is lost by the time the tooth appears in the mouth. The enamel spends the remainder of its lifetime vulnerable to wear, damage, and decay. In hopes of eventually replacing teeth, scientists from Japan have developed a new method for growing dental enamel."

    There was an article last year about someone coming up with using ultrasonic waves to trigger regrowth of teeth.

    AFAIK, it uses a rather well-known effect for stimulating bone growth, the same by which e.g. running makes your leg bones stronger. The article mentions uses related to the jaw and the roots of teeth, both of which are basically bone. On the other hand, enamel is a completely different tissue that cannot regenerate in adults because the cells are no longer around, as explained in the main article.

    The most recent studies most definitely do show that people who daily have a high intake of sugar through drinks like soda have a higher risk of developing type 2 diabetes.

    Perhaps you'd care to cite those studies, then?

    You might care to pass them on to the American Diabetes Association and Diabetes UK, both of which seem pretty clear that we're talking about a myth here. A quick Google will also turn up several recent research papers that do not show the link you assert.

    You do realize that the typical way to 'produce' diabetic rats is feeding them fructose, right?

    There is a rather interesting correlation between the timelines of companies replacing table sugar in the sugar water drinks with fructose and a dramatic increase in the number of diabetic people.

    You are probably right in that sugar as in sucrose doesn't cause diabetes, but that's not what is generally in sodas these days, having been replaced by cheaper fructose.
