NewsResearchers find unexpectedly large methane source in overlooked landscape
Researchers reported that upland landscapes were releasing some of the highest methane emissions yet documented among northern terrestrial ecosystems. The research was sparked when a greenhouse gas began ballooning under lawns in Fairbanks.

NewsBacteria encode hidden genes outside their genome - so do we?
A new study shows that bacteria can create free-floating and ephemeral genes, raising the possibility that similar genes exist outside of our own genome.

NewsInfected bacteria fight back with ‘hidden’ genes that halt cell growth, slow viral spread
Researchers have uncovered a surprising way bacteria defend themselves: when a bacterium is infected, bacterial enzymes that copy genetic information from RNA into DNA synthesize genes whose protein products help shut down cell growth.

NewsMarine algae use massive enzymes of unprecedented size to biosynthesize fish-killing toxins
Marine algae Prymnesium parvum use massive enzymes dubbed PKZILLAs – some of the largest proteins ever to be identified in nature – to make large and complex prymnesin neurotoxins responsible for mass fish kills during harmful algal blooms worldwide.

NewsSuperbugs spread to family members of recently hospitalized patients
Family members of patients recently discharged from hospital may have a higher risk of getting an antibiotic-resistant infection, even if the patient was not diagnosed with the same infection, suggesting hospitals play a role in community spread of resistant bacteria.
