Scientists have discovered two new mechanisms for how a well-established antibiotic works, paving the way for the potential development of new antibiotic treatments.

Every human cell has millions of ribosomes that make proteins. For decades, biologists thought of ribosomes as tiny, uniform machines. But now a Stanford Medicine team is showing that ribosomes are much more interesting and complicated than previously thought.

Viruses lack the molecular machinery required for protein synthesis. Instead, they hijack the host's protein-making machinery, specifically ribosomes and translational factors. This process is essential for viral multiplication and infection. Viruses have RNA genomes or mRNAs con

Macrophages are considered the "scavenger cells" of the immune system, but some pathogens exploit these very cells as hiding places. Researchers from the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg and Philipps-Universität Marburg have discovered a mec

Uma lacuna em um ponto crucial das moléculas do ribossomo, a fábrica de proteínas da célula, faz com que espécies de água rasa façam menos agregações tóxicas de proteína. Segundo pesquisadores, essa particularidade teria surgido junto à expansão de seus cérebros.

Segundo o Observatório Nacional (ON), descoberta é resultado de pesquisas na área de Astrobiologia, ciência que investiga como a vida surgiu, evoluiu e se distribui pelo Universo O post Açúcar encontrado no espaço pode mudar tudo o que sabemos sobre a origem da vida apareceu primeiro em Olhar Digital.

The nucleolus is a liquid-like cellular organelle where protein factories called ribosomes are assembled. Researchers knew of three distinct compartments within the nucleolus, but how these compartments function to drive ribosome assembly was unclear. A study from St. Jude Childr

In a study published in Nature Communications, researchers at Karolinska Institutet have mapped key steps in the assembly of the mitochondrial ribosome, offering new clues to how defects in this process can lead to disease.

In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked so closely in tandem that they were effectively attach

The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene circuit' platform that can simultaneously read multiple

Pesquisadores criaram um sistema capaz de realizar um ciclo celular completo e reacenderam um antigo debate da biologia: afinal, o que define a vida? O post Nova célula sintética consegue crescer e se dividir, mas ainda não é considerada viva apareceu primeiro em Olhar Digital.
