Experiments in animals and observations in humans suggest that the amount of proline circulating in one’s plasma has a strong association with depression severity.

Researchers link a stretch of DNA to a peptide of interest and measure current changes as the molecule is pulled by a helicase through a nanopore.

Adapting DNA nanopore sequencing to peptides allows researchers to identify single amino acid differences.

Through his studies on cancer-causing viruses, the University of California, Los Angeles, professor has helped develop lifesaving treatments.

The Stanford University professor helped develop a technique to grow brain organoids from induced pluripotent stem cells.

A mixture of chemicals induces reactions reminiscent of life on pyrite.

Dampening the immune response to stay up in the air may have helped bats become tolerant to viral infections.

Fruit flies and mice grow better and eat less when the amino acid balance of their food reflects that coded by their exomes.

Cancer cells exhibit altered metabolic processes that may serve as promising targets for new therapies.

How cancer cells fuel their rapid growth

The amino acids left behind in a human fingerprint can be used to determine whether an individual is male or female.

New research points to key properties of transfer RNA molecules and amino acids that may have supported the origin of life on Earth.

A new experimental system demonstrates that precursors of ribonucleotides, amino acids, and lipids may have simultaneously arisen from the same prebiotic chemistry.

For the first time, synthetic DNA base pairs are replicated within living bacteria.

Rodent models of Huntington’s disease show dysfunctional cysteine production, and adding the amino acid to their diets seems to relieve symptoms.
