Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
Analysis of two decades" worth of antibiotic resistance shows antibiotic use is not the only driver of superbugs
For the first time, researchers have analyzed the impact of antibiotic use on the rise of treatment-resistant bacteria over the last 20 years in the UK and Norway. They show that while the increase in drug use has amplified the spread of superbugs, i.....»»
Valve now allows the “vast majority” of AI-powered games on Steam
New reporting system will enforce "guardrails" for "live-generated" AI content. Can you tell which of these seemingly identical bits of Steam iconography were generated using AI (trick question, it's none of them). (credit: Auric.....»»
Notorious cell subpopulation key to antibiotic failure, say scientists
Antibiotic overuse can lead to antibiotic resistance, but classic antibiotic resistance might not completely explain why antibiotics sometimes fail. Sub-populations of bacteria called persister cells can survive in the presence of lethal doses of ant.....»»
Plant warfare: The crucial function of Nrc proteins in tomato defense mechanisms
In the fascinating world of plant biology, a study recently featured on the cover of The Plant Journal has been turning heads. The research delves into the intricate defense mechanisms of tomatoes against the notorious bacterial pathogen Pseudomonas.....»»

Novel chemical recycling system for vinyl polymers of cyclic styrene derivatives
Chemical recycling of widely used vinyl polymers (VPs) is one of the key technologies required for realizing a sustainable society. In this regard, a team of researchers from Shinshu University have recently reported a new chemical process that facil.....»»
Transmitting a domino reaction using redox chemistry achieved for the first time
Domino reactions occur when the transformation of one chemical group stimulates the reaction of another attached group, or another molecule, leading to a rapid knock-on effect through the system like a row of falling dominoes. Researchers at Hokkaido.....»»
Creating novel amino acid nanoparticles with enhanced anticancer activity
Amino acids, such as tyrosine and tryptophan, are the fundamental building blocks that make up proteins. These biomolecules have different chemical groups on each end and side chain, and so, have the natural ability to form a chain through the format.....»»
A computer vision and machine learning system that monitors and controls workup processes
A team of chemists and engineers at the University of British Columba working with colleagues at pharmaceutical company Pfizer has developed a chemical processing system combining computer vision with a real-time machine-learning monitoring system fo.....»»
Exploring how antibiotic-resistant bacteria become aggressive
Some strains of antibiotic-resistant bacteria that have recently acquired disease-enhancing genes may not behave as aggressively as expected, according to a Northwestern Medicine study recently published in Nature Communications......»»
Experimental antibiotic kills deadly superbug, opens whole new class of drugs
The relatively large molecule clogs a transport system, leading to lethal toxicity. Enlarge / This Scanning Electron Microscope image depicts several clusters of aerobic Gram-negative, non-motile Acinetobacter baumannii bacteria.....»»
Research team combines two catalysts to make common chemical production safer, more environmentally friendly
The chemical industry has long been shadowed by unwelcome images of billowing smokestacks and pipes discharging toxic effluent. Modern manufacturing practices have done much to mitigate the industry's environmental impact, but there remains room for.....»»
A new approach can address antibiotic resistance to Mycobacterium abscessus
Scientists at St. Jude Children's Research Hospital are tackling Mycobacterium abscessus (Mab) antibiotic resistance. This naturally antibiotic-resistant pathogen is becoming more prevalent, highlighting the urgent need for novel therapeutics. To add.....»»
Size and shape of inhaled asbestos nanofibers may be exclusively responsible for pulmonary fibrosis
The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fiberglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. The r.....»»
Scientists discover why chicken farms are a breeding ground for antibiotic resistant bacteria
Scientists from the University of Nottingham are one step closer to understanding how bacteria, such as E. coli and Salmonella enterica, share genetic material which makes them resistant to antibiotics......»»
Evolutionary "U-turn" may mitigate antibiotic resistance, study finds
In a scientific breakthrough, Monash University researchers have discovered a revolutionary "U-turn" in the evolution of antibiotic resistance, challenging the widely accepted notion that traits once developed are irreversible......»»
High levels of mercury traced to particular cell types in brains of mammals
Exposure to mercury (Hg) is extremely neurotoxic in most chemical forms. Even scientists who study mercury compounds are at risk due to potential exposure to Hg. Renowned physicist Michael Faraday suffered from Hg poisoning due to prolonged exposure.....»»
Evolution is not as random as previously thought, finds new study
A new study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease, and climate change......»»
Study demonstrates potency of synthetic antibiotic against serious chronic infections
A new synthetic antibiotic developed by University of Liverpool researchers is shown to be more effective than established drugs against "superbugs" such as MRSA, a new study shows......»»
Using electricity, scientists find promising new method of boosting chemical reactions
As the world moves away from gas towards electricity as a greener power source, the to-do list goes beyond cars. The vast global manufacturing network that makes everything from our batteries to our fertilizers needs to flip the switch, too......»»
