What makes a pathogen antibiotic-resistant?
Antimicrobial resistance is a story of constantly moving parts and players. With every new or tweaked antibiotic or antimicrobial drug, the targeted pathogens begin the evolutionary dance of acquiring resistance, prompting researchers to constantly d.....»»
Light-based photocatalytic system can break down PFAS at room temperature
Researchers at Colorado State University have found a new approach for breaking down PFAS—a group of human-made "forever" chemicals commonly used for their water-resistant properties that can carry health risks from long-term exposure......»»
River microbes near wastewater treatment plants express high levels of antibiotic resistance genes, study shows
Rivers and streams serve as critical connectors across vast geographical landscapes, trickling out of tucked-away headwaters and snaking thousands of miles toward oceans and deep seas. These waterways directly impact human and environmental health, a.....»»
Engineered antibiotic D22 shows promise against drug-resistant bacteria
Antibacterial drugs are important for treating infections. But increasingly, bacterial resistance to current drugs—so they don't work well, or even at all—means new ones are urgently needed......»»
Collaboration key to ultimate genotypes in plants and livestock, say researchers
University of Queensland researchers are setting the agenda for breeding high yield, heat tolerant and disease-resistant crops and low emission cattle with excellent feed conversion efficiency as they search for the ultimate genotype......»»
Flies carry bacteria, and some are resistant to antibiotics—evidence from three South African hospices
Houseflies live close to humans and domesticated animals and because they are so mobile they can easily spread bacteria that make people sick......»»
First successful synthesis of elusive antibiotic compounds since their discovery 50 years ago
Back in 1974, German researchers discovered peculiar chemical compounds, present as red pigments in soil bacteria from a volcanic crater. These biomolecules, which came to be known as naphthocyclinones, are representative of a family of antibiotics w.....»»
Scientists propose drug-free method to combat antibiotic-resistant bacteria
Recent estimates indicate that deadly antibiotic-resistant infections will rapidly escalate over the next quarter century. More than 1 million people died from drug-resistant infections each year from 1990 to 2021, a recent study reported, with new p.....»»
Scientists shed light on an arms race between barley and a fungal pathogen
Scientists from the Leibniz Institute of Plant Biochemistry (IPB), together with partners from the University of Cologne, have discovered a new group of defense substances in barley that are effective against a broad spectrum of fungal pathogens. One.....»»
COP29: AI can help develop climate-resistant crops for Africa—but it shouldn"t be left in the hands of corporates
How we use land and feed a growing global population, and the burden we place on natural habitats in pursuit of nutrition, will again take center stage at the annual global climate change conference, COP29, in November......»»
Green shoots spring from ashes in Brazil"s fire-resistant savanna
The huge wildfires that ripped through Brazil recently did not spare its vast tropical savanna, but green shoots are already emerging from the ashes there, proof of the vast grasslands' rare gift for fire resistance......»»
Study reveals superbug MRSA"s double defense against antibiotics
Scientists have discovered the mechanism which allows the superbug methicillin resistant Staphylococcus aureus (MRSA) to become highly resistant to antibiotics, paving the way for new approaches to control infectious disease......»»
Using machine learning to identify bacterial resistance genes and the drugs to block them
Antibiotic resistance is a growing public health problem around the world. When bacteria like E. coli no longer respond to antibiotics, infections become harder to treat......»»
New study explores adoption of robotic weeding to fight superweeds
Most corn and soybean fields in the U.S. are planted with herbicide-resistant crop varieties. However, the evolution of superweeds that have developed resistance to common herbicides is jeopardizing current weed management strategies. Agricultural ro.....»»
African giant rats trained to sniff out illegal wildlife products
In the past, African giant pouched rats have learned to detect explosives and the tuberculosis-causing pathogen. Now, a team of researchers have trained these rats to pick up the scent of pangolin scales, elephant ivory, rhino horn, and African black.....»»
New gold nanorod technology can fry bacteria to sterilize implants
In the fight against antibiotic resistance, a new technology developed at Chalmers University of Technology, in Sweden, can be of great importance when, for example, hip and knee implants are surgically inserted. By heating up small nanorods of gold.....»»
Scientists uncover key mechanism in pathogen defense, paving way for new antimicrobial strategies
Researchers have made a significant breakthrough in understanding how certain pathogens defend themselves against the host's immune system......»»
New class of encrypted peptides exhibits significant antimicrobial properties
In a significant advance against the growing threat of antibiotic-resistant bacteria, researchers have identified a novel class of antimicrobial agents known as encrypted peptides, which may expand the immune system's arsenal of tools to fight infect.....»»
Bacterial pathogen must balance between colonizing airways and developing antibiotic tolerance, study reveals
Imagine trying to settle into a new home while constantly being attacked. That's what the bacterium Pseudomonas aeruginosa faces when it infects the lungs, and it can't both spread and protect itself from antibiotics at the same time......»»
Study shows weak external electric fields may protect crops from infection
Research from Dr. Giovanni Sena's group in the Department of Life Sciences highlights an intriguing method to help protect plants from pathogen attacks using weak electric fields......»»
Nanomedicine advances deliver precise antibiotic doses to fight infections and drug resistance
Researchers from the University of Waterloo have developed a new technology that can hold an entire course of antibiotics in one tiny dose and deliver on demand just the right amount of medication that a particular patient needs to fight an infection.....»»
