A system of polyphenylalanine synthesis was optimized for a comparison of the polymerizing activities of ribosomes from spores and vegetative cells of Bacillus cereus T. Ribosomes of both types react similarly, showing a magnesium optimum of about 6mM and spermidine optima of about 5mM and 4mM for vegative and spore ribosomes, respectively. These lead to optimum mono- to multivalent cation rations of 9 and 10 respectively at 100 mM ammonium ion. A comparison of the response of these ribosomes to suboptimal concentrations of magnesium and spermidine show that they differ qualitatively from each other, suggesting that they possess different structure, macromolecular or ionic components.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.
