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.

NewsGlobal research uncovers critical weakness in malaria parasite
Scientists exploring how immunity develops against Plasmodium falciparum found that broadly reactive antibodies from various individuals consistently bound to the same site on a key virulence protein of the malaria parasite.

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 ...

NewsFederal needle exchange programs are cost-effective to reduce health care costs, blood-borne infections
Needle exchange programs are evidence-based strategies that prevent transmission of blood-borne viruses, reduce injection-related infections, improve access to medical care, and facilitate entry into substance dependence programs for people who inject drugs, says a new study.

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.
