Volcanic eruptions dump ash into the ocean, affecting life miles deep. This study reveals that iron from this ash shapes deep-sea microbes, with key genes playing a major role. Viruses aren't direct players in iron cycling but impact it through breaking down iron-processing microbes. These findin...

Boosting the potential of algae to tackle climate change, scientists engineered a tiny bug that turns carbon into fuel! By tweaking an enzyme in cyanobacteria, they ramped up production of energy-rich alcohols by over 50%. This achievement marks a breakthrough in using biology to create sustainab...

When tackling nitrite stress, enriched sludge systems showed unique strengths using sodium propionate or acetate. Propionate systems kept working better under low stress thanks to energy benefits, while acetate systems shone under high stress, quickly breaking down glycogen to fight nitrites. Mai...

Ancient soil digs in Turkiye reveal a hidden past: from the Chalcolithic to Early Iron Age, soil samples show diverse bacteria and antibiotic-resistance genes. They've found antibiotic resistance stretching back to those ancient times, linked to human activity. This highlights how human impact is...

Antibiotic resistance isn't as straightforward as once thought. E. coli can develop resistance and tolerance to antibiotics in unexpected ways. Some mutants became highly tolerant but needed fewer antibiotics to be inhibited—a twist on what experts expected! These changes can happen without a cle...

Guess what? <i>Salmonella</i> isn't just one bad bug—it's often a mix of many. In chicken farms, about 18% of samples had multiple types, with one, called Kentucky, being a bit of a bully, often keeping others out. While 17% of young chicken flocks had <i>Salmonella</i>, older ones hit 41%. Even...

Way back in Earth's history, low oxygen levels helped ancient structures called stromatolites thrive. In a specific region of China, these formations show diverse shapes and reveal how changes in oxygen and microbial life were linked. This study unveils essential clues about how early life evolve...

Cystic fibrosis messes up mucus clearance in the lungs, leading to bacterial infections and lung damage. Pseudomonas aeruginosa is a tough bug thriving in CF lungs, using biofilms to shield against antibiotics. It adapts fast, hiding from the immune system and becoming hard to kill. Understanding...

Concrete cracks in seawater can be tough to fix due to extreme conditions, but scientists have evolved a bacteria, *Sporosarcina pasteurii*, to handle high salinity and alkalinity. This strain not only survives but thrives, boosting concrete strength significantly. They're uncovering the genetic...

Microbial food safety faces a huge threat as bacteria like Salmonella and E. coli become resistant to antibiotics. This review highlights how misuse in agriculture and healthcare is a big driver.
