The nitrogen in the gum was found to be in nitrogen heterocycles, which are the building blocks of nucleobases in DNA and RNA ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular ...

Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other ...

Dr. Cech is a biochemist and the author of the forthcoming book “The Catalyst: RNA and the Quest to Unlock Life’s Deepest Secrets,” from which this essay is adapted. From E=mc² to splitting the atom ...

Some 39,000 years ago, a woolly mammoth died in present-day Siberia, destined to be blanketed by ice and permafrost that would end up preserving its body — even down to the hair and muscle. Now, that ...

Scientists have sequenced RNA from a nearly 40,000-year-old woolly mammoth leg, the oldest ancient RNA ever recovered. These ...

A new role has been uncovered for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part ...

Many writers grouse when an editor makes a change in a story, but the consequences of changing a single word usually aren’t that dire. Not so with genetic instructions for making proteins. Even a ...

From enzymes and lipid nanoparticles to large-scale process design, four global innovators redefine RNA-based medicine development and delivery.
