New research moves closer to harnessing viruses to fight bacteria and reduce antibiotic use

Posted: 20 Dec 2021 09:06 AM PST

A new study has cast new light on how to best combine antibiotics and phage therapy. Researchers conducted laboratory experiments on Pseudomonas aeruginosa a bacterium which causes disease in immunocompromised and cystic fibrosis patients. They exposed the bacterium to eight types of antibiotics -- and found differences in the mechanisms by which the bacteria evolve resistance to phages, which affect how harmful they are.

A pathway emerges: Biologists describe structure and function of a heme transport and assembly machine

Posted: 20 Dec 2021 09:00 AM PST

Researchers described for the first time the structure of a bifunctional protein, called CcsBA, that transports heme and attaches it to cytochromes. The study captured two conformational states of CcsBA, a bacterial and chloroplast protein, allowing scientists to characterize the enzyme mechanism.

Small measures can be a big help for children of mothers with depression

Posted: 20 Dec 2021 05:31 AM PST

Several new studies among Syrian refugee families in Turkey and families with infants in Sweden and Bhutan show that children of mothers in poor mental health risk falling behind in their cognitive development. However, very small changes can suffice to break this correlation and enable the children to return to their normal developmental level. Having plenty of people around them and an available community are two of the most important factors for helping children, in all three countries.
