NewsUpper surface of coastal waters can accumulate bacteria and antibiotics
Antibiotics in the uppermost water surface, known as the sea surface microlayer, can significantly affect the number of bacteria present and contribute to the adaptation of marine bacteria against widely used antibiotics. In new research presented at ASM Microbe, scientists directly assessed the potential effects of antibiotics ...

News2,000-year-old shipworm mystery solved - its destructive skills are down to bacterial symbionts
Scientists have discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the shipworm gut called the ’typhlosole’, have the ability to secrete the enzymes needed to digest lignin—the toughest part of wood.
