Past coronavirus infections don’t seem to help with SARS-CoV-2
Neither T nor B cells seem to use memory of one virus to attack the other. Enlarge / False color image of viruses attached to a cell's surface. (credit: NIAID) While the SARS-CoV-2 virus is new to humans, coronaviruses in general aren't. There.....»»
Brazilians choke as fire smoke blankets 80% of country
With as much as 80 percent of Brazil under a blanket of smoke from historic wild fires, face masks last used during the coronavirus pandemic are coming out again......»»
Study finds good nutrition boosts honey bee resilience against pesticides, viruses
In a new study, researchers at the University of Illinois Urbana-Champaign tackled a thorny problem: How do nutritional stress, viral infections and exposure to pesticides together influence honey bee survival? By looking at all three stressors toget.....»»
How cyber compliance helps minimize the risk of ransomware infections
Over the past decade, ransomware has been cemented as one of the top cybersecurity threats. In 2023 alone, the FBI received 2,385 ransomware complaints, resulting in over $34 million in losses. To help businesses combat ransomware and other threats,.....»»
Genome sequence analysis identifies new driver of antimicrobial resistance
Antibiotics are a lifesaving tool. Yet, due to their chronic overuse, microbes are evolving and developing immunity against them. As a result, once-effective medications can no longer stave off infections, complicating treatment and increasing mortal.....»»
Genetic tracing at the Huanan Seafood market further supports COVID animal origins
A new international collaborative study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of meta.....»»
Light-induced immunoassay can selectively detect coronavirus spike proteins in five minutes
Like moths to a flame, microbes can also be moved by light. Using this knowledge, researchers from Osaka Metropolitan University's Research Institute for Light-induced Acceleration System (RILACS) have demonstrated a method to detect the presence of.....»»
Harmless strain of E. coli bacteria may be able to prevent urinary tract infections
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) and the College of Engineering are collaborating on a project that uses harmless strains of E. coli bacteria to disrupt the bacteria responsible for urinary.....»»
Scientists identify 18 bacterial strains to treat antibiotic-resistant gut infections
Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enteroba.....»»
Newly discovered antimicrobial could prevent or treat cholera
More than a million people each year die from infections by pathogens that are resistant to antimicrobials, and the problem is growing. Meanwhile, the discovery of new antimicrobials that can help stem the tide has not kept pace......»»
Study proves transfer of feline coronavirus between domestic and wild cats
A new study from College of Veterinary Medicine researchers finds the first genetic evidence of feline coronavirus (FCoV) transmission between a captive wild and a domestic cat......»»
How viruses move through insects for transmission of diseases
Viruses are master parasites that have adapted to infect many host species. Some viruses even use multiple hosts to spread their infections—such as arboviruses that use insects to move their infections to mammalian hosts like humans. Understanding.....»»
Crispr-Enhanced Viruses Are Being Deployed Against UTIs
With antibiotics losing their effectiveness, one company is turning to gene editing and bacteriophages—viruses that infect bacteria—to combat infections......»»
Silver nanoparticles and a new sensing method can fight back against antibiotic-resistant biofilms
From safeguarding our food supply to preventing hospital infections, the battle against antibiotic-resistant bacteria is a growing challenge. Some bacteria can form biofilms, thick aggregates of millions of individual cells surrounded by protective m.....»»
Studying fungi"s "weak link" to fight global rise in deadly fungal infections
A group of scientists at the Department of Energy's Oak Ridge National Laboratory have conducted neutron scattering research to reveal key information about fungus cell membranes that could aid in developing new antifungal treatments......»»
Neolithic bones reveal isolated Yersinia pestis infections, not pandemics
Since the catastrophic pandemics of the Middle Ages, one disease has almost proverbially symbolized contagion and death: the plague. It is now known that the plague bacterium Yersinia pestis has been present in Central and Northern Europe for more th.....»»
Phage editing technology could lead to alternative treatments for antibiotic-resistant bacteria
As antibiotic resistance becomes an increasingly serious threat to our health, the scientific and medical communities are searching for new medicines to fight infections. Researchers at Gladstone Institutes have just moved closer to that goal with a.....»»
Algorithm maps protein degradation patterns to improve infection diagnosis and treatment
Peptides are small fragments of proteins, mainly found in the skin and mucous membranes. Some peptides act as a barrier, protecting the body against infections by fighting off microorganisms like bacteria, viruses, and other pathogens, while others p.....»»
Examining experiences of the pandemic requires a more critical eye, says researcher
The coronavirus pandemic was, in many ways, a unique period whose impacts are still being seen and felt today. The effects of the pandemic live on in people's memories, fears, hopes, and bodies......»»
New discovery of how bacteria navigate their environment could change how we treat infection
Scientists from the University of Sheffield have discovered a new sensory capability in bacteria which could transform treatments for bacterial infections......»»
Promising antibiotic candidates discovered in microbes deep in the Arctic Sea
Antibiotics are the linchpin of modern medicine: without them, anyone with open wounds or needing to undergo surgery would be at constant risk of dangerous infections. Yet we continue to face a global antibiotics crisis, as more and more resistant st.....»»
