Alpha amino acids' stability may explain their role as early life's protein building blocks
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 ...
In a peer-reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor (LUCA) is the single life form that branched into ...
A new study suggests a surprisingly simple compound could help fight Alzheimer’s disease. Researchers found that arginine—an inexpensive amino acid already considered safe—can reduce the buildup of ...
