Miniaturized version of ribosome found in microsporidia

A research team lead by MIMS/SciLifeLab research group leader Jonas Barandun, Umeå University, Sweden, uses cryo-electron microscopy to provide near atomic details of the smallest known eukaryotic cytoplasmic protein synthesis ...

Virus found to adapt through newly discovered path of evolution

Bucking a central tenet of biology, researchers at the University of California San Diego and their colleagues have discovered evidence for a new path of evolution, and with it a deeper understanding of how quickly organisms ...

New findings detail how virus prepares to infect cells

(PhysOrg.com) -- Researchers have learned the atomic-scale arrangement of proteins in a structure that enables a virus to invade and fuse with host cells, showing precisely how the structure morphs with changing acidity to ...

Image pinpoints all 5 million atoms in viral coat

(PhysOrg.com) -- If a picture is worth a thousand words, then Rice University's precise new image of a virus' protective coat is seriously undervalued. More than three years in the making, the image contains some 5 million ...

New findings reveal how influenza virus hijacks human cells

Influenza is and remains a disease to reckon with. Seasonal epidemics around the world kill several hundred thousand people every year. In the light of looming pandemics if bird flu strains develop the ability to infect humans ...

Protein quality control and mitochondria

Protein aggregates are toxic for mitochondrial function, and thus disrupt the supply of chemical energy to their host cells. An LMU team has characterized a protein complex that prevents the build-up of such deposits in the ...
