A new bacterial blueprint to aid in the war on antibiotic resistance
A team of scientists from around the globe, including those from Trinity College Dublin, has gained high-res structural insights into a key bacterial enzyme that may help chemists design new drugs to inhibit it and thus suppress disease-causing bacte.....»»
A guide to "big team science" creates a blueprint for research collaboration on a large scale
Scientific research depends on collaboration between researchers and institutions. But over the past decade, there has been a surge of large-scale research projects involving extraordinarily large numbers of researchers, from dozens to hundreds, all.....»»
Researchers uncover novel physiological functions of CRISPR-Cas guard RNA
How the expression of Cas proteins in bacterial CRISPR-Cas immune system adapts to the constantly changing CRISPR structures and crRNA expression levels has been a long-standing unresolved question......»»
Characterization of methicillin-resistant Staphylococcus aureus from ready-to-eat foods in China
The objective of a new study published in the journal Zoonoses was to determine the prevalence, antimicrobial resistance, virulence profiles, and molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) obtained from ready-to-e.....»»
Patrolling honey bees expose spread of antimicrobial resistance
Bees could become biomonitors, checking their neighborhoods to determine how far antimicrobial resistance (AMR) has spread, according to research by Macquarie University scientists......»»
Study finds a large proportion of Michigan"s C. jejuni infections are caused by antibiotic resistant strains
Working with the Michigan Department of Health and Human Services, Michigan State University researchers have shown that antibiotic resistance genes are prevalent in the bacterium Campylobacter jejuni, a leading cause of foodborne illness......»»
Antibiotics found to promote the growth of antibiotic-resistant bacteria in the gut
Antibiotic-resistant bacteria get extra nutrients and thrive when the drugs kill "good" bacteria in the gut. This is according to new research led by Imperial College London scientists, which could lead to better patient risk assessment and "microbio.....»»
Newly-engineered versions of bacterial enzyme reveal how antibiotics could be more potent
Modern medicine depends on antibiotics to treat infections by disabling targets inside bacterial cells. Once inside these cells, antibiotics bind to certain sites on specific enzyme targets to stop bacterial growth. Randomly occurring changes (mutati.....»»
Novel chemosensor-based method for rapid detection of bacterial toxin
The COVID-19 pandemic made it very clear that we need better methods to quickly screen for dangerous pathogens and substances. One such compound that regularly flies under the radar is lipopolysaccharide (LPS), largely known as "endotoxins.".....»»
A promising bacterial suicide gene against citrus Huanglongbing and canker
Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus (CaLas), is the No. 1 killer of citrus trees worldwide. HLB causes billions of dollars in annual economic losses to the global citrus industry......»»
The mobile game funding a revolution in Myanmar
Resistance to the military has come in many forms, including the development of an app-based game......»»
How bees can monitor pollution for us: Everything from toxic metals to antimicrobial resistance
Our cities are complex places of work, industry and residential activities. This often makes it hard to pin down the spread of different contaminants throughout them......»»
A cave on Borneo has been used for 20,000 years: 400-year-old rock art depicts colonial resistance
The islands of South-East Asia record a long and dynamic human history of technological innovation, migration and conflict......»»
Salmonella outbreak brings CDC warning over small turtles
Public health officials are currently investigating a multi-state outbreak of Salmonella, a bacterial disease that causes diarrhea, fever and stomach cramps. According to an August 2023 investigation notice by the Atlanta-based Centers for Disease Co.....»»
Fluid dynamics researchers shed light on how partially submerged objects experience drag
One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing it to a steady flow to measure its resistance in the form of drag. Studies on drag resist.....»»
New antibiotic from microbial "dark matter" could be powerful weapon against superbugs
A new powerful antibiotic, isolated from bacteria that could not be studied before, seems capable of combating harmful bacteria and even multi-resistant "superbugs." Named Clovibactin, the antibiotic appears to kill bacteria in an unusual way, making.....»»
A low-tech sludge solution for reducing antimicrobial resistance
A low-tech solution to help farmers make more money from their muck could also help reduce the spread of antibiotic resistance from sewage and manure, according to scientists at The James Hutton Institute in Aberdeen and Center for Environmental Heal.....»»
How microhabitat affects bacterial communities in a semi-arid ecosystem
Known as the living skin of dryland ecosystems, biocrust contains diverse soil microorganisms that are essential to biocrust formation and the maintenance of multiple ecological functions......»»
Research gives new insights into the role food intake plays in fighting antimicrobial resistance
Cooking food thoroughly and avoiding some types of vegetables and salad during a course of antibiotic treatment could potentially reduce antibiotic resistance, by preventing bacteria carrying resistance genes getting into the gut, according to a new.....»»
Towards organ preservation: Animal resistance to cold reflected in stem cells
Researchers led by Genshiro Sunagawa at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have shown that an animal's stem cells possess the same level of cold resistance as the animal itself......»»
Beneficial bacteria sense gut mucus to stay in the right place, at the right time
Beneficial gut bacteria actively sense the mucus lining of the gut, using this information as a guide to stay in their proper place, new research from the University of Oregon shows. Breakdowns in that communication can lead to abnormal bacterial beh.....»»
