Has Artificial Life Been Created?

Greg Laden says:

I think it has been created over the last few months but the announcement is delayed for obvious reasons … nobody wants the equivilant of “Cold Fusion” tacked to your resume.

Surely that will get you to follow the read it all link!

Fructan You

Or, how to get medications into your colon when needed.
Oral delivery of drugs to treat colon ailments is made problematic by the normal actions of the stomach and small intestine. There is a promising new approach to solving this problem:

Researchers at the University of Guadalajara, in Mexico, have discovered that fruit compounds taken from the blue-agave plant used to make tequila can be employed as an effective method of delivering drugs to the colon. …
It has been known for many years that the blue-agave plant contains a polysaccharide known as fructan, a polymer of fructose. The compound is not hydrolyzed in acidic environments, such as the upper digestive tract, and it’s therefore able to reach the intestine fully intact.

They do not say whether the new medication delivery systems will work better with or without salt and lime.
Hmmm, and will increased demand for the blue-agave for medical purposes drive up the price of tequila?
You bet!


Foot Circles

Go ahead, try it:

1. While sitting at your desk, lift your right foot off the floor and make clockwise circles with it.
2. Now, while doing this, draw the number “6” in the air with your right hand. Your foot will change direction!

Same thing happens with the left foot. Can you keep your foot going clockwise?
Can anyone explain the mechanisms in play here?
