How did life originate? Ancient proteins may hold important clues. Every organism on Earth is made up of proteins. Although ...

The Universitat Autònoma de Barcelona (UAB) forms part of an international consortium that is preparing the Tree of Sex ...

A study has found that an ancient protein motif that binds to nucleic acids is functionally "ambidextrous." This means that ...

Secondary metabolites play essential roles in plant adaptation, defense, and ecological interactions, yet their evolutionary dynamics and functional ...

New research challenges the view that proteins are the only key to evolution, highlighting the importance of lipids.

For the past semester, students at UW-La Crosse have not only been advancing their knowledge in the classroom, they've been ...

Eukaryogenesis occurred suddenly, driven by the growing length of genes and the limitations on producing longer proteins. An ...

Molecular evolution is the area of evolutionary biology that studies evolutionary change at the level of the DNA sequence. It includes the study of rates of sequence change, relative importance of ...

A new study shows the tradeoff between power and efficiency in muscles is governed by proteins that form a molecular tuning ...

Sterols are among the most abundant lipids in eukaryotic cells, yet are synthesized through notoriously long, complex metabolic pathways. Researchers have used a novel approach to show how they ...

Some stinky plants independently evolved an enzyme to take the same molecule behind our bad breath and turn it into the smell of rotting flesh.

Chemistry professor Chris Chang’s lab studies the chemical biology of the elements, specifically examining the roles that ...
