One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...
Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet capable of the fundamental steps of self-replication. They call it QT45 — ...

RNA strand that can almost self-replicate may be key to life's origins
Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...
A team of researchers used a new technique, called high-resolution template matching, or HRTM, to uncover in unprecedented detail the movement of ribosomes -- the molecular structures that synthesize ...
Proteins of all sizes and shapes do most of the work in living cells, and the DNA sequences in genes spell out the instructions for making those proteins. The crucial job of reading the genetic ...
Stanford Medicine researchers have developed a blood test capable of detecting cancers, the ways cancer resists treatments and tissue injury caused by non-cancerous conditions.
