NewsMicrobial oxidation in glacial rivers and lakes could help mitigate methane emissions
A new study suggests microbes in glacial rivers and lakes may play a crucial role in mitigating the effects of methane, a powerful greenhouse gas that recent studies have shown emerging as glaciers melt in warming global temperatures.

NewsA dial for tuning the immune system: Discovery sheds light on why COVID makes some sicker than others
A new study identifies an “immune system tuning dial,” which originated as a bug in the genetic code tens of millions of years ago. When this signaling goes awry and leads the body to under or overreact, people are more likely to develop severe or Long COVID.

NewsResearchers develop model to evaluate food safety control strategies for produce industry
You’ve probably heard of product recalls involving lettuce, spinach, or other leafy greens. Consuming these popular vegetables are among the main causes of food poisoning, affecting thousands of people every year. Leafy greens can become contaminated with pathogenic E. coli or other bacteria through splashes of soil or contaminated irrigation ...

NewsDiverse phage populations coexist on single strains of gut bacteria
A new study shows that a single bacterial species, the host of a phage, can maintain a diverse community of competing phage species. Several phage species coexist stably on a population of a genetically uniform strain of E. coli.
