It is often said that exercise is the best medicine, but for many older adults, it can be a prescription that is increasingly ...

Researchers from UNIGE and Marburg show that D-cysteine, the "mirror" form of cysteine, selectively targets certain cancer ...

If you have ever cooked on a gas stove or seen a flame flicker to life with the turn of a knob, you have seen natural gas in action. Supplying that energy at scale, however, is far more complicated.

Twenty canonical amino acids exist in nature, encoded by the universal genetic code and translated by the proteins and RNA that make up the ribosomal machinery. Expansion of the genetic code to new ...

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 ...

Amino acids have long been known to improve the stability and solubility of proteins. Amino acids might be added to insulin, for example, to maintain shelf-life and stop undesired chemical reactions ...

It’s hard to imagine many kitchens without soy sauce. Thanks to its deep umami flavor, easy accessibility and salty kick, we splash it on stir-fries, marinate meats with it, drizzle it over rice and ...

For decades, amino acids have been added to medical formulations like insulin as stabilizers: these small molecules keep proteins (i.e. larger particles) from interacting in undesirable ways. And for ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

Amino acids are absolutely essential to our health—and for life itself. They are the so-called “building blocks” of proteins. They play a key role in the growth, repair, and maintenance of almost ...
