By freezing a crucial phosphoric acid complex to near absolute zero, scientists uncovered a single, unexpectedly stable structure at the heart of proton transport.

A long-standing mystery in bile acid biology has been solved. Bile acids are often introduced as digestion helpers, but they are also powerful chemical messengers that help coordinate metabolism ...

A novel method to manipulate the inner structure of cells connects several scientific fields and could represent a ...

Peptide nucleic acids (PNAs) represent a revolutionary class of synthetic nucleic acid analogues, in which the traditional sugar–phosphate backbone is replaced by a neutral N-(2-aminoethyl) glycine ...

Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing ...

Amino acids have long been known to improve the stability and solubility of proteins. Amino acids might be added to insulin, for example, to maintain shelf-life and stop undesired chemical reactions ...

A new study from the Hebrew University of Jerusalem published in the Proceedings of the National Academy of Sciences sheds light on one of life's greatest mysteries: why biology is based on a very ...
