In 2023, NASA’s OSIRIS-REx spacecraft collected samples of 4.6-billion-year-old rocks from an asteroid called Bennu and ...
Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an ...
The discovery is just the latest to come from the asteroid sample, which dates back to the dawn of the solar system.
The flowing of molten rocks through small cracks in the heart of volcanoes may have been a perfect environment to forge the building blocks of life on Earth. These chemicals—called biopolymers—are an ...
"We found an unexpected chemical complexity, with abundances far higher than predicted by current theoretical models." ...
Proteins are the building blocks of life. These biomolecules comprise chains of amino acids that fold into precise shapes to perform specific jobs in nature. But these elegant structures form only ...
