The eukaryotic ribosome unveils its structure

One year after the Nobel Prize in chemistry was awarded for the discovery of the bacterial ribosome's atomic structure, French researchers from the Institut de Genetique et de Biologie Moleculaire et Cellulaire have determined ...

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 ...

Evolution still scientifically stable

An international team of researchers, including Monash University biochemists, has discovered evidence at the molecular level in support of one of the key tenets of Darwin's theory of evolution.

Why eukaryotes, not bacteria, evolved complex multicellularity

Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around ...

Quorum sensing: Researchers examine bacteria communication

European researchers at Linköping University in Sweden are showing how bacteria control processes in human cells through a process called quorum sensing. This phenomenon is where bacteria talk to each other via molecules ...

Researchers crack mystery of swirling vortexes in egg cells

Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients ...
