The bacteria that look after us and their protective weapons
The extensive agriculture that makes it possible to meet the nutritional needs of the planet's billions of inhabitants is based on the use of chemical products (pesticides) to avoid crop losses due to pests. However, these pesticides have a negative.....»»
Bacteria encode hidden genes outside their genome; do we?
Since the genetic code was first deciphered in the 1960s, our genes have seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why.....»»
Predicting metabolic potential in bacteria from limited genome data
How bacteria eat food, and what kinds of products they can make from that food, is dictated by the metabolic network of enzyme patterns encoded in their genomes. Using computational methods to learn these patterns across a large number of known bacte.....»»
Smells may prime our gut to fight off infection
Many organisms react to the smell of deadly pathogens by reflexively avoiding them. But a recent study from the University of California, Berkeley, shows that the nematode C. elegans also reacts to the odor of pathogenic bacteria by preparing its int.....»»
Researchers create new device for on-the-spot water testing
Researchers at University of Galway have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria......»»
New nasal microbiome: Depriving multi-resistant bugs of iron
A research team led by Simon Heilbronner, Professor of Microbiology at LMU's Biocenter, has investigated how various bacteria that colonize the nasal cavity deal with the lack of iron there and interact with one another......»»
Bacterial gut diversity improves the athletic performance of racehorses
The composition of gut bacteria of thoroughbred racehorses at one month old can predict their future athletic performance, according to a new study from the University of Surrey. In the study, foals with lower bacterial diversity at 28 days old also.....»»
Double whammy antibiotic makes antibiotic resistance much harder—new study
Most antibiotics are natural products of bacteria and other microorganisms from the environment. They are part of a silent chemical warfare among microorganisms in soils, rivers and seas right now. The fact that they are natural products that have be.....»»
Coinfecting viruses obstruct each other"s cell invasion
The process by which phages—viruses that infect and replicate within bacteria—enter cells has been studied for over 50 years. In a new study, researchers from the University of Illinois Urbana-Champaign and Texas A&M University have used cutting-.....»»
New compound found to be effective against "flesh-eating" bacteria
Researchers at Washington University School of Medicine in St. Louis have developed a novel compound that effectively clears bacterial infections in mice, including those that can result in rare but potentially fatal "flesh-eating" illnesses. The com.....»»
Peregrine falcons mount a comeback in Yosemite, thanks to rock climbers
Four decades ago, fragile falcon eggs were saved from certain death by Ken Yager and a small team of expert climbers from a nest on Yosemite's El Capitan sheer granite wall, as protective parents dive-bombed from the sky......»»
Engineered microbes found to repel mosquitoes
Genetically-engineered human skin bacteria can make mice less attractive to mosquitoes for 11 days. Mosquitoes transmit a host of deadly diseases, including malaria, West Nile, dengue, yellow fever, and Zika. Female mosquitoes on the hunt for a blood.....»»
Green synthesis of copper oxide nanoparticles from mangifera indica: A solution for agricultural disease management
A research team has successfully synthesized green copper oxide nanoparticles (CuO.NPs) from Mangifera indica (M. indica) leaf extract. The CuO.NPs showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on p.....»»
How bacteria attach their cloaks of invisibility to immune defenses
Bacteria have different strategies for protecting themselves. Some bacterial pathogens surround themselves with a shell made of many sugar chains that lie close together, also known as capsular polymers. This protects the bacteria from drying out and.....»»
Scientists convert bacteria into efficient cellulose producers
Bacteria produce materials that are of interest to humans, such as cellulose, silk and minerals. The advantage of producing bacteria in this way is that it is sustainable, takes place at room temperature and in water. A disadvantage is that the proce.....»»
Researchers develop 3D printed model for targeted antibiotic therapy against follicular infections
Hair follicle infections are often difficult to treat because bacteria settle in the gap between hair and skin, where it is difficult for active substances to reach them......»»
Exploring the effects of initial microbiota on microbial succession during eggplant fermentation
Shibazuke is a traditional Japanese eggplant pickle produced by the process of fermentation using lactic acid bacteria (LAB). LAB which are commonly present in vegetables cause the spontaneous fermentation of vegetables, resulting in the distinctive.....»»
New aerospace and building materials could repair themselves thanks to fungi and bacteria
Researchers are using biological matter to create unique new materials that can adapt to their environment and repair themselves......»»
How Staphylococcus slips around between biological environments
It's an unpleasant fact that most of us are happy to ignore: Our mouths and noses are the natural homes to infectious and antibiotic resistant bacteria......»»
Woman who went on the lam with untreated TB is now cured
The woman realized how serious her infection was once she was in custody. Scanning electron micrograph of Mycobacterium tuberculosis bacteria, which cause TB. (credit: National Institute of Allergy and Infectious Diseases).....»»
Blue light could kill at least 99% of bacteria linked to dog ear infections, new research shows
New research from the University of Nottingham and University of Birmingham has highlighted that blue light has the ability to kill antibiotic-resistant strains of bacteria isolated from ear infections in dogs......»»
