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 ...

But thanks in part to trees planted in areas where the two fungi don’t grow well, the American chestnut isn’t extinct. And efforts to revive it in its native range have continued, despite the long ...

Different DNA Structures Nucleate the Folding of Proteins to form specific complexes that modulate the readout of ...

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

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 ...

Abstract Cancer cells precisely modulate replication stress to sustain genomic instability without triggering lethal DNA damage, yet regulators ...

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 ...

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 ...

The London biotech will develop small-molecule therapies to target a pathway some cancer cells use to lengthen their life ...

A child’s health doesn’t start at birth. It begins with the environment in the womb—the nutrients the mother consumes, any ...

A Mediterranean cohort study evaluated a DNA methylation biomarker of alcohol intake and compared it with conventional ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...
