Social bacteria build shelters using the physics of fingerprint patterns

Forest-dwelling bacteria known for forming slimy swarms that prey on other microbes can also cooperate to construct mushroom-like survival shelters known as fruiting bodies when food is scarce. Now a team at Princeton University has discovered the physics behind how these rod-shaped bacteria, which align in patterns like those on fingerprint whorls and liquid crystal displays, build […]

Gut Bacteria Linked to Weight Gain Following Chemotherapy Treatment for Breast Cancer

Marking Breast Cancer Awareness Month, researchers say they eventually hope to identify women at risk and offer methods to prevent weight gain following chemotherapy. Image credit: Pixabay (Free Pixabay license) Approximately 30% of breast cancer patients who receive chemotherapy treatment gain weight, though it is unclear why this phenomenon occurs in some women but not in […]

Fats fighting back against bacteria

Droplets of fat inside our cells are helping the body’s own defence system fight back against infection, University of Queensland researchers have discovered. The international collaboration between UQ Institute for Molecular Bioscience researchers Professor Robert Parton and Professor Matt Sweet, and the University of Barcelona’s Professor Albert Pol found that these fat droplets are both a food source and weapon against bacterial […]

Scientists use bacteria as micro-3D printers

A team at Aalto University has used bacteria to produce intricately designed three-dimensional objects made of nitrocellulose. With their technique, the researchers are able to guide the growth of bacterial colonies through the use of strongly water repellent – or superhydrophobic – surfaces. The objects show tremendous potential for medical use, including supporting tissue regeneration […]

Bacteria ensure better use of biomass

Despite Danish biogas plants operating at full capacity, only about half of the energy content from the raw materials is converted into biogas. This is because a large proportion of the biomass received—e.g. straw and other biomass with a high lignin content—can not be digested by the biogas plant bacteria.  Lignin is a carbon compound […]

Drug-resistant hospital bacteria persist even after deep cleaning, genomic study reveals

Scientists have used genome sequencing to reveal the extent to which a drug-resistant gastrointestinal bacterium can spread within a hospital, highlighting the challenge hospitals face in controlling infections. Enterococcus faecium is a bacterium commonly found in the gastrointestinal tract, where it usually resides without causing the host problems. However, in immunocompromised patients, it can lead to […]

Gut bacteria associated with animal-based diet may mitigate risk of cardiovascular disease

Oregon State University researchers have found that a type of common gut bacteria sometimes associated with inflammation, abscesses, bowel disease and cancer has a major silver lining: It seems to help prevent cardiovascular disease. The findings suggest the possibility of probiotic treatments for atherosclerosis, the dangerous buildup of fats, cholesterol and other substances in arteries […]
