Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...

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 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...

Life on Earth rests on a knife-edge of chemistry that could easily have tipped the other way. As geochemists reconstruct the planet’s birth, they are finding that a narrow band of oxygen conditions ...

Researchers have identified a molecular brake that limits DNA replication in healthy cells, revealing how cells prevent a long-suspected replication catastrophe and pointing to a potential ...

Haoyu Cheng, Ph.D., assistant professor of biomedical informatics and data science at Yale School of Medicine, has developed a new algorithm capable of building complete human genomes using standard ...

Researchers have uncovered the enzyme behind chromothripsis, a chaotic chromosome-shattering event seen in about one in four ...

Solar energy is a possible alternative, but while we have become reasonably good at storing solar electricity in lithium-ion ...

A research team led by UAB researcher David Reverter has discovered the molecular mechanism that describes in detail the ...

These random molecules were fed a collection of three-base-long RNAs, each linked to a chemical tag. The idea was that if a molecule is capable of ligating one of these short RNA fragments to itself, ...

Mitochondria possess their own mRNA translation system, mediated by specialized mitoribosomes. Dysregulation of mitochondrial translation disrupts metabolic homeostasis and is linked to various ...
