Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque ...

Kim M. Keeling is in the Department of Biochemistry and Molecular Genetics, Heersink School of Medicine, University of Alabama at Birmingham, Alabama 35294, USA. Messenger RNA molecules encode the ...

MIT scientists have found that an amino acid called cysteine can help the gut heal itself. In mouse studies, a cysteine-rich diet activated immune cells that release a molecule speeding up tissue ...

Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to be the way it is? A recent ...

In short, AHAs work by exfoliating, and that process makes skin look instantly more refreshed. Though a scrub can also remove dead cells, chemically exfoliating with alpha hydroxy acid products can go ...

The code of life is simple. Four genetic letters arranged in triplets—called codons—encode amino acids. These are the building blocks of proteins, the machinery that powers life. But the genetic code ...

We’ve heard of GMOs, but this is ridiculous. Scientists at the Medical Research Council’s Laboratory of Molecular Biology say they’ve engineered a bacteria whose genetic code is more efficient than ...

The DNA of nearly all life on Earth contains many redundancies, and scientists have long wondered whether these redundancies served a purpose or if they were just leftovers from evolutionary processes ...

Liquid culture flasks of bacteria grown in yellow broth covered with tinfoil on a shaker. Bacterial strains needed to be tested every step of the way to create the highly compressed genome. Credit: ...
