(Phys.org)—Is it possible to engineer self-replicating nanomaterials? It could be if we borrow nature's building blocks. DNA is a self-replicating molecule where its component parts, nucleotides, have specific chemical ...
(Phys.org)—Biologist Rami Pugatch of Princeton's Simons Center for Systems Biology has characterized the self-replication process of Escherichia coli according to a scheduling policy model derived from industrial processes. ...
New York University scientists have developed artificial structures that can self-replicate, a process that has the potential to yield new types of materials. The work, conducted by researchers in NYU's Departments of Chemistry ...
