When a molecule of tryptophan absorbs ultraviolet light, it glows faintly as it releases energy at a lower frequency. This ...

DeepMind says its AlphaFold tool has successfully predicted the structure of nearly all proteins known to science. The AI lab is offering its database of over 200 million proteins to anyone for free.

The prediction of protein structure is difficult for a few reasons. First, there is a huge search space — every possible 3D position for each atom in each amino acid. Second, proteins chemically ...

Researchers at UT Southwestern Medical Center have discovered that a diet free of the amino acid tryptophan can effectively halt the growth of liver cancer in mice. Their findings, published in ...
