The origin of life on Earth is one of the most challenging questions in science. In the last 60 years, considerable progress has been made in understanding how simple molecules relevant to life can be generated spontaneously or are known to arrive to Earth from space. Additionally, analysis of...
Question: Origin of Life: How did the first self-replicating molecules originate on Earth, and what were the conditions that allowed for the transition from simple organic molecules to complex life forms?Consciousness: What are the biological and neurol...
said jeffrey bada, a chemist at the scripps institution of oceanography, who was not involved with the work. it shows that rna molecules "could have carried out their replication in the total absence" of the more sophisticated biological machinery that life now possesses. "this is a nice ...

Molecular nanotechnology is principally concerned with building things precisely from individual molecules or atoms; miniaturization is inherent and ultimate, and when reliable mechanosynthetic operations can be employed, precise, uniformly defect-free products become feasible. These characteristics enable the ...
The Y-integrases typically catalyze recombination between homologous sites present on the cellular genome and the circular double-stranded DNA (dsDNA) molecules of the MGEs. Thorough analysis of the piPolB-encompassing genomic regions allowed us to define the precise integration sites for many pipolins...
