Phys.org / Life with one less: Engineered bacteria break the 20-amino-acid rule

One of life's many mysteries is how it ended up choosing only a set of 20 amino acids to build proteins for its wide catalog of organisms, from single-celled bacteria to behemoth whales. From a chemical standpoint, many of ...

Phys.org / Why isolated human groups speak more diverse languages even as genetic diversity shrinks

Languages and human DNA both capture aspects of human diversity. But how are they related? A new international study led by the University of Zurich finds a clear but counterintuitive pattern: regions with high genetic diversity ...

Phys.org / Unraveling the evolution of an extraordinary photosynthesis in a tropical tree species

Plants use sunlight to convert water and carbon dioxide into energy-rich sugars and oxygen in various ways (photosynthesis). Drought is a major challenge in this process. A research team led by Wolfram Weckwerth at the University ...
