MicroRNAs (miRNAs) — a class of small RNAs with a role in the regulation of gene expression — had until now been found only in multicellular organisms. Now, Wang, Qi and colleagues provide the first ...

Metacaspases, ancestral homologues of the caspase family, are pivotal cysteine proteases found in a wide range of unicellular organisms, including yeasts, algae, and phytoplankton. These enzymes ...

Australian researchers have uncovered how a particular strain of a diarrhea-causing parasite managed to infect more animal ...

This separation of sexes in plants is called dioecy. One reason why dioecy may evolve is because of the negative effects that ...

Animals reproduce in a variety of fascinating ways. Some species, including humans and many other mammals, give birth to live young that develop inside the mother’s body. Others reproduce through less ...

The discovery of a billion-year-old fossil in Scotland offers exciting new insight into animal evolution, BC researcher says Loch Torridon in Scotland, where the microfossil was discovered. Photo: ...

Viruses typically aren’t considered ‘alive,’ as many core biological functions are outsourced to their potential hosts. But a newly discovered organism appears to straddle the line between virus and ...

Biochemical and physiological mechanisms of adaptation of organisms to the marine environment. Special emphasis is on biological responses to temperature, salinity, carbon dioxide, pH and bicarbonate ...
