Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
'Lonely' bacteria increase risk of antibiotic resistance
Scientists from The University of Manchester have discovered that 'lonely' microbes are more likely to mutate, resulting in higher rates of antibiotic resistance.
Scientists understand how E. coli clone has become globally distributed
Scientists have for the first time come closer to understanding how a clone of E. coli, described as the most important of its kind to cause human infections, has spread across the world in a very short time. ...
Human DNA shows traces of 40 million-year battle for survival between primate and pathogen
Examination of DNA from 21 primate species - from squirrel monkeys to humans - exposes an evolutionary war against infectious bacteria over iron that circulates in the host's bloodstream. Supported by experimental ...
New research could revolutionize genomic sequencing of drug-resistant bacteria
New nanopore DNA sequencing technology on a device the size of a USB stick could be used to diagnose infection - according to new research from the University of East Anglia and Public Health England.
Learning anti-microbial physics from cicada
(Phys.org) —Inspired by the wing structure of a small fly, an NPL-led research team developed nano-patterned surfaces that resist bacterial adhesion while supporting the growth of human cells.
Another reason to be thankful: Turkeys may be lifesavers
While the turkey you eat on Thursday will bring your stomach happiness and could probably kick-start an afternoon nap, it may also save your life one day.
New antibiotic in mushroom that grows on horse dung
Researchers from the Institute of Microbiology at ETH Zurich have discovered a new protein with antibiotic properties in a mushroom that grows on horse dung. Researchers are now exploring the various potential ...
A possible alternative to antibiotics
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Tick protein does the trick to fight infection
A protein in ticks that protects them against the cold could inspire a new class of antibiotics for humans, according to a Yale University study.
Designer viruses could be the new antibiotics
Bacterial infections remain a major threat to human and animal health. Worse still, the catalogue of useful antibiotics is shrinking as pathogens build up resistance to these drugs. There are few promising ...
Using test tube experiments to study how bacterial species evolve antibiotic resistance
Given a critical change in the environment, how exactly, do species adapt? Professor Tom Vogwill and colleagues wanted to get at the heart of this evolutionary question by measuring the growth rates and DNA mutations of 8 ...
