Personalized biohybrid microswimmers for therapeutic cargo delivery

Tiny biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. The natural environmental sensing tendencies of bacteria mean they can navigate toward certain chemicals or be remotely controlled using magnetic or sound signals.

Giant viruses may possess the tools of metabolism in their genome

According to researchers from Virginia Tech, genes within viruses possess certain portions that help them make their own tools for metabolism. However, they do not have metabolic processes of their own. The new study with these findings appeared in the latest issue of the journal Nature Communications.

Study: Early introduction of solid foods may predispose infants to obesity

Infants who were started on solid foods at or before three months of age showed changes in the levels of gut bacteria and bacterial byproducts, called short-chain fatty acids, measured in their stool samples, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.

Paper-based device to detect coronavirus in wastewater

The coronavirus disease (COVID-19) has spread to180 countries and territories, affecting more than 850,000 people. The transmission of the coronavirus is through respiratory droplets. However, the risk of transmission through feces is low, based on data from previous coronavirus outbreaks. Though transmission of the novel coronavirus through sewerage systems is low, testing could help predict coronavirus outbreaks or spread.

Three Australian experts explain the course of COVID-19

Researchers have been studying the ongoing pandemic of COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) closely since its beginning in December 2019. To date, the virus has infected over 850,000 individuals across the globe and killed over 41,000.

Researchers develop chemically modified phage capsid that “stifles” influenza viruses

A new approach brings the hope of new therapeutic options for suppressing seasonal influenza and avian flu: On the basis of an empty - and therefore non-infectious - shell of a phage virus, researchers from Berlin have developed a chemically modified phage capsid that "stifles" influenza viruses.
