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 ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint ...

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 ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...

Sean Ryder, professor at UMass Chan Medical School, has written a book to delve the mysteries of ribonucleic acid as a tool to fight diseases. Messenger ribonucleic acid, or mRNA, is in the public ...

People are still debating whether the mRNA from COVID-19 vaccines remains in the body longer than it should. Some say it lingers and causes harm, others say that idea just doesn’t hold up. A new ...

40,000-year-old RNA from permafrost-preserved tissue was recovered from a mammoth specimen known as Yuka. Molecular evidence from Yuka revealed a correction to the original assumption about Yuka’s sex ...

Scientists are consistently one-upping each other when it comes to finding the oldest molecules from fossils. The race even includes the notoriously fragile RNA. “It’s groundbreaking,” said Oliver ...
