Robinson Ridge in the east Antarctic

UNSW researchers have found their previous discovery of bacteria living on air in Antarctica is likely a process that occurs globally, further supporting the potential existence of microbial life on alien planets.

Whooping cough bacteria are becoming smarter at colonising and feeding off unwitting hosts, strengthening calls for a new vaccine, according to UNSW researchers.

One of the scourges of hospital infections – biofilms formed by bacteria that stick to living tissue and medical instruments – can be tricked into dispersing with the targeted application of nanoparticles and heat.

Inspired by bacteria able to thrive in the ocean’s inky depths, award-winning UNSW chemist Cyrille Boyer has for the first time used near-infrared light to create polymers – a discovery with implications for nanomedicine.

Microbes may be tiny, but their huge number and diversity mean they can be used to identify environmental impacts early, potentially limiting greater harm to larger organisms, write Katherine Dafforn, Emma Johnston, Inke Falkner and Melanie Sun.

A rapid evolutionary “arms race” between bacteria and the killer viruses they contain has been observed by a UNSW-led team of scientists in a sophisticated genetic study.
