Specialized cellular compartments discovered in bacteria

Researchers at McGill University have discovered bacterial organelles involved in gene expression, suggesting that bacteria may not be as simple as once thought. This finding could offer new targets for the development of ...

Molecular 'tails' are secret ingredient for gene activation

It might seem as though humans have little in common with the lowly yeast cell. Humans have hair, skin, muscles, and bones, among other attributes. Yeast have, well, none of those things.

Histone H3-H4 tetramer found to be a copper reductase enzyme

A team of researchers at the University of California has found that the histone H3-H4 tetramer is a copper reductase enzyme. In their paper published in the journal Science, the group describes two experiments they carried ...

Simulations show fundamental interactions inside the cell

Actin filaments have several important functions inside cells. For one, they support the cell membrane by binding to it. However, scientists did not know exactly how the actin interacts with the membrane lipids. Simulations ...

Expanding virophage diversity

Virophages are small viruses with double-stranded DNA genomes that co-infect eukaryotic cells along with giant viruses. Almost all known virophage genomes share only four genes in common: major and minor capsid proteins (MCP ...
