Scientists poring over a sample brought back from the asteroid Bennu have detected amino acids and complex mineral compounds, ...

Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's ...

The ab initio quantum mechanical model approach, which is focused on the electron structure, is considered to be highly accurate and able to examine both short-range and long-range interactions among ...

In a properly folded protein, hydrophobic amino acid residues are together, shielding each other from water molecules; hydrophilic residues are exposed on the surface of the protein, interacting ...

The discovery is a capstone achievement for NASA, which went to great lengths to secure and deliver asteroid samples from ...

thus encoding a protein of two alternating amino acids. Translation of the artificial GUGU mRNA yielded a protein of alternating cysteine and valine residues. However, this technique alone could ...

Proteins are made of strings of amino acids that resemble the strand in the image above. Using machine learning models, researchers were able to design the identity of amino acids on a computer to ...

In a new peer reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor is the single life form that branched ...

For each structural strain of tau fibrils, they identified amino acids without which the strain cannot form its signature ...
