(PhysOrg.com) -- A key element of both biotechnology and nanotechnology is – perhaps unsurprisingly – computational modeling. Frequently, in silico nanostructure design and simulation precedes actual experimentation. ...
The origin of life is seen as the formation of the first biomolecules which may be subject to multiplication and further development. Hitherto it was unclear, which reactions could have triggered the evolution of this ur-metabolism. ...
