A protein that guards cells against aging-related problems by protecting a particularly vulnerable set of genes has been identified by researchers from Stanford University and the VA Palo Alto Health Care System (VAPAHCS). The genes that encode components of the ribosome — the protein-making machine of the cell — are abundant and constantly in use… Read more

Each time you swallow food, cells that line your intestines must step up their activity in a sudden and dramatic manner. In fact, they rise to the challenge in the most economic fashion, according to a new study by Weizmann Institute of Science researchers. In economics or engineering, when one has to get production ramped-up… Read more

The most detailed three-dimensional images to date of an important step in the process by which cells make the nano-machines responsible for producing all-important protein has been created. The results, from Rockefeller University, are prompting the researchers to re-evaluate how they envision this early phase in the construction of ribosomes. The structure they determined, shown… Read more
