Primordial soup or crepes?

Article Abstract:

The polycondensation of long oligonucleotides and peptides on a mineral surface shows that the polymers that gave rise to life on Earth may have formed on a solid surface rather than in a solution. According to this model, minerals bind polyanions and the polymers cannot separate from the mineral beyond a certain chain length. Further elongation takes place on the mineral. However, life probably originated by spreading in a solution containing the polyanions, as the model requires a solution to provide the starting material.

Hyakutake's interstellar ices

Article Abstract:

Researchers studying the Hyakutake Comet have found an abundance of acetylene and ethane in its interstellar ice. This finding suggests that Hyakutake contains ice that formed in the Earth's natal interstellar cloud. However, researchers have yet to determine where Hyakutake was formed, whether in the Edgeworth-Kuiper disk or the Oort cloud. Conclusive findings on the origin of Hyakutake will help fortify the assumption that life on Earth began through comet impacts.

Momentum creation by vortices in superfluid 3Helium as a model of primordial baryogenesis

Article Abstract:

Momentum creation by vortices in superfluid 3Helium as a model of primordial baryogenesis was described by demonstrating experiments on spectral flow of superfluid 3Helium utilizing the alumnized Kapton film diaphragm. The behavior of leptons and quarks on fixed gauge can be modelled by the behavior of 3Helium excitations on fixed order parameter backgrounds such as quantized vortices.
