NewsThe geometry of life: Physicists determine what controls biofilm growth
The fitness of a biofilm is largely impacted by the contact angle that the biofilm’s edge makes with the substrate - and this geometry has a bigger influence on fitness than anything else, including the rate at which the cells can reproduce.

NewsE. coli variant may cause antimicrobial resistance in dogs and humans
Researchers studying antimicrobial-resistant E. coli – the leading cause of human death due to antimicrobial resistance worldwide – have identified a mechanism in dogs that may render multiple antibiotic classes ineffective.

NewsEarly life antibiotic increases risk of asthma: providing clues to a potential prevention adult asthma
Early exposure to antibiotics can trigger long term susceptibility to asthma, according to researchers who isolated a molecule produced by gut bacteria that in the future could potentially be trialed as a dietary supplement for children at risk of asthma.

NewsStudy unveils complexity of zoonotic transmission chains
Researchers have dissected the complex interactions involved in zoonoses, introducing the concept of a “zoonotic web,” a detailed network representation of the relationships between zoonotic agents, their hosts, vectors, food sources, and the environment.

NewsMost Salmonella illnesses from chicken caused by few products with high levels of virulent strains
A new study shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts, suggesting regulation efforts should focus on detecting and preventing high-risk contamination.

NewsScientists build roadmap to bioengineer plants that produce their own nitrogen fertilizer
Nitrogen fertilizers make it possible to feed the world’s growing population, but they are also costly, harm ecosystems and require a lot of energy to manufacture. However, a few plants have evolved the ability to make their own nitrogen with the help of bacteria. A new study helps explain how ...

NewsReceptors make dairy cows a prime target for influenza
Researchers who examined mammary gland samples from two cows infected with highly pathogenic avian influenza found a rich supply of sialic acid, which could shed light on how the virus attaches to hosts and help develop measures to slow the spread.

NewsHibernation status matters when white-nose syndrome pathogen infects bats
The fungal pathogen that causes white-nose syndrome (WNS) in bats uses different cell entry strategies depending on the host’s hibernation status – cold and inactive, or warm and active.

NewsDensely packed E.coli bacteria form immobile material similar to colloidal glass
Dense E.coli bacteria have several similar qualities to colloidal glass. When they become higher in density and more packed together, they form a ’glassy state’ but also show some other unique properties not typically found in glass-state materials.
