The ribosome by Wayne Decatur The 2009 Nobel Prize in Chemistry was awarded for studies of the ribosome. The ribosome is the machine in your cells that accurately and efficiently decodes the genetic information stored in your genome and synthesizes the corresponding polypeptide chain one amino acid at a time in the process of translation. These structures are considered landmarks for the fact they showed clearly the major contributions to decoding and peptide bond synthesis come from RNA and not protein, as well as for the sheer size of the structures determined. >>> Visit this page >>>	Geobacter pili: surprising function. Y Gu, V Srikanth, AI Salazar-Morales, R Jain, JP O'Brien, SM Yi, RK Soni, FA Samatey, SE Yalcin, NS Malvankar. Nature 2021 doi: 10.1038/s41586-021-03857-w Geobacter pili were long thought to be electrically conductive protein nanowires composed of PilA-N. Nanowires are crucial to the energy metabolism of bacteria flourishing in oxygen-deprived environments. To everyone's surprise, in 2019, the long-studied nanowires were found to be linear polymers of multi-heme cytochromes, not pili. The first cryo-EM structure of pili (2021) reveals a filament made of dimers of PilA-N and PilA-C, shown. Electrical conductivity of pili is much lower than that of cytochrome nanowires. Evidence suggests that PilA-NC filaments are periplasmic pseudopili crucial for exporting cytochrome nanowires onto the cell surface, rather than the pili serving as nanowires themselves. >>> Visit I3DC Interactive Visualizations >>>	Polio is still here! Polio vaccines have been available since the 1950s, but the challenges of vaccination in remote areas of Afghanistan and Pakistan have prevented worldwide eradication. In 2022, polio was found circulating in parts of New York State, USA. The polio virus has a small RNA genome enclosed in an icosahedral capsid composed of several proteins, shown cut in half. The structures of virus capsids can be explored using free FirstGlance in Jmol. >>> Visit I3DC Interactive Visualizations >>>
