The casual observer generally rejects the possibility of hydrocarbons occurring in the Precambrian basement rocks of Ohio and surrounding region. However, it appears that a major paradigm shift must ...

Very little is known about how and when over the course of evolution 3-D protein structures arose. In a new study, researchers resurrected four-billion-year-old Precambrian proteins in the laboratory ...

Since the original release of the Ohio seismic reflection profile by the Consortium for Continental Reflection Profiling (COCORP) in 1988, several interpretations have been presented for the structure ...
