NewsClimate anomalies may play a major role in driving cholera pandemics
New research suggests that an El Niño event may have aided the establishment of a novel cholera strain during an early 20th-century pandemic, suggesting climate anomalies could create opportunities for the emergence of new cholera strains.

NewsWarming stops tiny organisms working together
The single-celled organism Paramecium bursaria can absorb and host algae (Chlorella spp), providing benefits for both, but when scientists made the water 5°C warmer, the partnership stopped working – and the algae may even become parasitic.

NewsShared geographic origin of TB strain and human host could boost risk of infection
For some forms of tuberculosis, the chances that an exposed person will get infected depend on whether the individual and the bacteria share a hometown, according to a study comparing how different strains move through mixed populations in cities.

NewsSuper cally molecules take down tuberculosis
Researchers have identified and synthesised a group of molecules that can act against the cause of tuberculosis in a new way. The callyaerins act against TB by employing a fundamentally different mechanism compared to antibiotic agents used to date.

NewsGut microbes implicated in bladder cancer
A new study shows that gut bacteria can metabolise carcinogens and cause them to accumulate in distant organs, leading to tumour development.

NewsHuman clinical study launched using phage lysin to eliminate staph in the nasal microbiome
A “first-in-human” study with the novel drug candidate HY-133 began on 10 July with the recruitment of clinically healthy volunteers who tested positive for Staphylococcus aureus colonisation of the nose.
