Around the world, a handful of scientists are trying to create life from scratch and they’re getting closer.
Experts expect an announcement within three to 10 years from someone in the now little-known field of “wet artificial life.”
“It’s going to be a big deal and everybody’s going to know about it,” said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. “We’re talking about a technology that could change our world in pretty fundamental ways — in fact, in ways that are impossible to predict.”
That first cell of synthetic life — made from the basic chemicals in DNA — may not seem like much to non-scientists. For one thing, you’ll have to look in a microscope to see it.
“Creating protocells has the potential to shed new life on our place in the universe,” Bedau said. “This will remove one of the few fundamental mysteries about creation in the universe and our role.”
And several scientists believe man-made life forms will one day offer the potential for solving a variety of problems, from fighting diseases to locking up greenhouse gases to eating toxic waste.
Bedau figures there are three major hurdles to creating synthetic life: A container, or membrane, for the cell to keep bad molecules out, allow good ones, and the ability to multiply; A genetic system that controls the functions of the cell; A metabolism that extracts raw materials from the environment as food and then changes it into energy.
