Scientists and engineers since the 1940s have been toying with the idea of building self-replicating machines, or von Neumann machines, named for John von Neumann. With recent advances in 3D printing ...

SpaceX is racing through the transition from its second-generation Starship hardware to a taller, more capable Version 3 just ...

Non-replicating vaccines are based on recombinant viral vectors that are made replication non-competent, meaning that these vectors are sufficient to induce host immune responses but cannot replicate ...

The genome is organized into distinct 1–2 Mb bands that contain numerous origins, which are coordinated to replicate in a programmed manner during S phase. These bands represent subunits of chromosome ...

When it comes to solving the world’s development challenges, the innovation agenda needs to expand beyond the invention of cool, cutting-edge solutions, and zero in on addressing the more mundane but ...

“We are trying to, if you like, invent a completely new way of designing robots that doesn’t require humans to actually do the designing,” said Alan Winfield. “We’re developing the machine or robot ...

Three hallmarks of life are that it can replicate, metabolize molecules to build and power itself, and compartmentalize these different reactions. Sijbren Otto and coworkers at the University of ...

A 3D printer that could re-create itself from lunar material is in development at a university in Canada. The technology could one day enable humans to 3D-print lunar bases, as well as conduct ...

Four different experts respond: Rob Rosenberger is a computer consultant who maintains the Computer Virus Myths Homepage. He replies: The roots of the modern computer virus go back to 1949, when ...
