MOJAVE NATIONAL PRESERVE, Calif. — J. Craig Venter, the maverick scientist, is looking for a new world to conquer — Mars. He wants to detect life on Mars and bring it to Earth using a device called a digital biological converter, or biological teleporter.

Although the idea conjures up “Star Trek,” the analogy is not exact. The transporter on that program actually moves Captain Kirk from one location to another. Dr. Venter’s machine would merely create a copy of an organism from a distant location — more like a biological fax machine.

Still, Dr. Venter, known for his early sequencing of the human genome and for his bold proclamations, predicts the biological converter will be his next innovation and will be useful on Earth well before it could ever be deployed on the red planet.

The idea behind it, not original to him, is that the genetic code that governs life can be stored in a computer and transmitted just like any other information.
