Stargate Replicators are here

I am beginning to find that the news articles I linked to a couple of years ago are no longer around. To preserve my record I guess I'm going to have to capture here the text I would like to keep. Please forgive me if my postings get to be too wordy.

For the Stargate fans out there we have this.

Scientists at the Cornell University in Ithaca, New York have created small robots that can build copies of themselves.

Each robot consists of several 4-inch (10-centimeter) cubes that have identical machinery, electromagnets to attach and detach to each other and a computer program for replication. The robots can bend and pick up and stack the cubes.
