Researchers found 14 of the 20 amino acids that life on Earth uses to make proteins. NASA makes it clear that its findings do not show evidence of extraterrestrial life itself, but that under the ...

Titan's frigid lakes of methane have been a hotspot for speculation about life as we don't know it ever since NASA's Cassini ...

Dworkin is the project scientist for NASA’s OSIRIS-REx mission ... Afterward, they measured which type of amino acid each ribozyme preferred. To make it clear, ribozymes are like tiny tools ...

This raises questions about how and why life on Earth "turned left" in its amino acid preference. NASA launched the OSIRIS-REx mission to asteroid Bennu in 2016 to gain insights into the early ...

Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's essential ingredients. NASA's Bennu asteroid samples reveal building blocks ...

A groundbreaking study has revealed a surprising biochemical connection between plant immune responses and human neurological health. Researchers have discovered that the metabolic pathways regulating ...

This important study uses advanced computational methods to elucidate how environmental dielectric properties influence the interaction strengths of tyrosine and phenylalanine in biomolecular ...

A big question in the origin of life on Earth is why it is based solely on "left-handed" amino acids. Studies on asteroid Bennu's chemical building blocks deepens the mystery.
