Researchers infer chemical steps involved in methylthiolation of tRNAs

Recent research revealed the chemical steps in a vital cellular modification mechanism that inserts a chemical tag to certain RNAs. Interference of this process in humans can result in cancers, diabetes, and neuronal diseases.

Newly identified antibacterial mechanism could inspire novel strategies to combat bacterial pathogens

Similar to how a spider traps its prey, the cells of the human immune system cooperate to trap and “eat” bacteria.

Study could help choose the ideal DNA extraction method for microbiome research

Let's face it, we are a results-driven society. Too focused on the outcome, people don't often think about the "how." For instance, did you think about "how" you got to work this morning or did you just get there? In microbiome studies the results are the graphs and the data but the "how," like commuting, is often just part of a routine.

Study reveals how autoimmune antibodies can predict severe cases of COVID-19

The presence of special immune system defense molecules, called autoimmune antibodies, has been strongly tied to how poorly people fare when hospitalized with COVID-19, a new study shows.

Study explores the efficiency of CasMINI, an engineered CRISPR-Cas system

A compact CRISPR-Cas system, known as CasMINI, can be employed for gene-therapy and cell-engineering applications as it is easier to deliver into cells.

Gut bacteria may play a key role in neurological damage of premature infants

Extremely premature infants are at a high risk for brain damage. Researchers at the University of Vienna and the Medical University of Vienna have now found possible targets for the early treatment of such damage outside the brain: Bacteria in the gut of premature infants may play a key role.

Research shows how dendrimers avoid detection by the immune system

Tiny synthetic particles known as dendrimers have been shown to avoid detection by our immune system and so could be used to develop a new system to deliver drugs into the body without triggering a reaction.

Study details the role of PANoptosome in activating innate immune response

Immunologists discovered how immune sensors in infected cells organize and initiate an immune response to infections with living bacteria and viruses.

Insights on cross-resistance can improve potency of sequential antibiotic treatment

A new study notes that sequential treatment with antibiotics that are similar but often swapped around can effectively kill bacteria and avoid drug resistance.

Small synthetic molecules could one day cure or prevent COVID-19, herpes

In addition to antibodies and white blood cells, the immune system deploys peptides to fight viruses and other pathogens.

Accurate diagnosis of bacterial superinfection pneumonia could help avoid antibiotic overuse

Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
