| 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. |
| 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. |
| Posted: 20 Dec 2021 05:31 AM PST A new study shows an increased risk of patients developing illnesses including mental ill-health and heart conditions if they have a GP-inputted medical history of gum disease. |
| Wearable biosensors can help people with complex health conditions Posted: 20 Dec 2021 05:31 AM PST Remote monitoring of health-related behavior with wearable sensor technology is feasible for people with complex health conditions, shows a recent study. |
| 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. |

| New study associates mask laws to reduction of COVID-19 deaths Posted: 15 Dec 2021 11:21 AM PST Countries without face mask mandates experienced significantly higher COVID-19 deaths per million than countries that enacted mask mandates, investigators report in a new study. |
| Uncovered: Key to how exercise protects against consequences of aging Posted: 15 Dec 2021 11:21 AM PST Scientists have discovered an enzyme that is key to why exercise improves our health. The discovery opens up the possibility of drugs to promote this enzyme's activity, protecting against the consequences of aging on metabolic health. |
| Sugar-coated COVID-19 test strip takes advantage of coronavirus' sweet tooth Posted: 15 Dec 2021 10:27 AM PST A sugar-coated COVID-19 test strip is effective at detecting all known coronaviruses, including variants, according to a new study. |
| Normal 6-month outcomes in babies of women with COVID-19 during pregnancy Posted: 15 Dec 2021 10:26 AM PST Babies born to women who had COVID-19 during pregnancy showed reassuring patterns of growth and development at 6-month follow-up, according to a new study. |
