The impact origin of genetic material

Medical Hypotheses, 1992
It is proposed that high velocity asteroidal impacts with the Earth created polymeric nucleotide sequences out of monomeric nucleotides via direct compressive forces. The developed model describes the simultaneous formation of histone-equivalent proteins and RNA/DNA-equivalent template structures as a natural and expected consequence of bolide ...

Impact of cellular materials

2010
Cellular materials are used as impact energy absorbers due to their large densification strain at the plateau stress during the plastic compression. For a cellular rod struck by a rigid object, the critical impact velocity is determined. If the impact velocity is higher than the critical impact velocity, the elastic wave will be followed by plastic ...

The Impact Crater as a Habitat: Effects of Impact Processing of Target Materials

Astrobiology, 2003
Impact structures are a rare habitat on Earth. However, where they do occur they can potentially have an important influence on the local ecology. Some of the types of habitat created in the immediate post-impact environment are not specific to the impact phenomenon, such as hydrothermal systems and crater lakes that can be found, for instance, in post-
