What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Scientists have used DNA's self-assembling properties to engineer intricate moiré superlattices at the nanometer ...

During DNA replication, the classic double helix can temporarily rearrange into an alternative structure known as a DNA three-way junction (3WJ). These configurations form a well-defined central ...

Scientists have twisted DNA into programmable nanostructures that form themselves — and could reshape future materials for light, sound, and electronics.

Inside each cell of the human body are proteins that control which genes are expressed at the right place and time. However, ...

Paleontology has just reached a major milestone with the discovery of intact proteins in fossils dating back to the Miocene. This breakthrough, published in Nature, is based on the analysis ...
