Viruses can hitch a ride on bacteria
The interaction of fungi and bacteria in the transport of viruses in the soil ecosystem has been examined by a UFZ research team in a study recently published in The ISME Journal. The scientists showed a novel mechanism of viral transport by bacteria.....»»
Unexpected phage protein function discovered in bacteria battle
An unexpected find has enabled important progress to be made in the battle against harmful bacteria. An international team of researchers, led by Professor Peter Fineran from the University of Otago, investigated a particular protein used by bacteria.....»»
The geometry of life: Physicists determine what controls biofilm growth
From plaque sticking to teeth to scum on a pond, biofilms can be found nearly everywhere. These colonies of bacteria grow on implanted medical devices, our skin, contact lenses, and in our guts and lungs. They can be found in sewers and drainage syst.....»»
Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Certain bacteria or fungi could combat a plant pathogen that attacks common vetch
Anthracnose, a severe disease caused by the Colletotrichum spinaciae plant pathogen, often occurs in common vetch, a widely grown legume. Chemicals are not recommended for disease management because the plants are used as livestock feed. A new study.....»»
"Sacrifice" of virus data clears the path to open a disease discovery pipeline
Tens of millions of still-unknown or misunderstood viruses can cause diseases—including new pandemics—and affect the health of valuable terrestrial and marine environments......»»
Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
Intracellular mechanisms shown to promote spread of deadly bacterial infection
Northwestern Medicine investigators have discovered novel protein mechanisms that promote the rapid spread of Vibrio vulnificus, a rare but lethal bacteria that can cause vibriosis and sepsis, according to findings published in the Proceedings of the.....»»
Features of H5N1 influenza viruses in dairy cows may facilitate infection, transmission in mammals
A series of experiments with highly pathogenic H5N1 avian influenza (HPAI H5N1) viruses circulating in infected U.S. dairy cattle found that viruses derived from lactating dairy cattle induced severe disease in mice and ferrets when administered via.....»»
New microbe-central model predicts global grassland soil pH under climate change
In a study published in One Earth on July 5, a research team led by Prof. Deng Ye from the Research Center for Eco-Environmental Sciences of the Chinese Academy of Sciences proposed the core-bacteria-forecast model (CoBacFM), which links the changes.....»»
Study reveals how stress pathways activate a cell"s emergency response procedures
Mayday! SOS! Distress signals like these are used around the world to indicate an emergency. The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if t.....»»
How the Lincoln Nautilus surprisingly won me over with its ride, huge screen
How I stopped worrying and learned to love the big screen. Enlarge / In the past, car companies engaged in "horsepower wars." Now it seems they're competing in a screen size war. (credit: Jonathan Gitlin) It's important.....»»
AI approach optimizes development of antibody drugs
Proteins have evolved to excel at everything from contracting muscles to digesting food to recognizing viruses. To engineer better proteins, including antibodies, scientists often iteratively mutate the amino acids—the units that are arranged in a.....»»
Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as w.....»»
Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors" reproduction ability
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought......»»
Study reveals rapid evolution and global spread of Pseudomonas aeruginosa
Pseudomonas aeruginosa—an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions—evolved rapidly and then spread globally over the last 200 years, probably driven b.....»»

How studying bat viruses can help prevent zoonotic disease
Bats have become the poster child of emerging zoonotic disease. The creatures harbor a vast array of viruses—some of which cause deadly diseases in humans—yet they rarely get sick themselves......»»
Exploring the molecular basis of how pradimicin A binds to viral N-glycan, a potential SARS-CoV-2 entry inhibitor
HIV, Ebola and most recently, COVID-19 viruses have had an enormous impact on our societies world-wide. All these viruses are "enveloped viruses," viruses that have an exterior envelope that surrounds them largely composed of their host's cells. This.....»»
NordVPN File Checker protects users from infected files
NordVPN launches its third experimental product from the NordLabs platform. File Checker is an online tool that scans different types of files for malware and viruses. It helps to prevent malicious codes invading user’s devices through infected or.....»»
Experts warn of sewage, E. coli in Missouri River: Flooding could make quality worse
The Kansas Department of Health and Environment advised residents last week to stay out of the Missouri River due to contamination from raw sewage and E. coli bacteria. Five days later, the river is still dangerous to enter—both due to high water l.....»»
