How to neutralize the SARS-CoV-2 virus
In the absence of effective treatments for COVID-19, many countries have approved the therapeutic use of blood plasma from recovering patients because it contains antibodies against the coronavirus. But not every type of antibody can neutralize the v.....»»
H5N1 strain of bird flu found in milk: WHO
The H5N1 bird flu virus strain has been detected in very high concentrations in raw milk from infected animals, the WHO said Friday, though how long the virus can survive in milk is unknown......»»
Bird flu in cattle: What are the concerns surrounding the newly emerging bovine H5N1 influenza virus?
The confirmed presence of bird flu in American dairy cattle in a March 25 report from the U.S. Department of Agriculture (USDA)—and a case in Texas where a human working with cattle was infected—has put Canadian public health experts on high aler.....»»
Honey bees experience multiple health stressors out in the field
It's not a single pesticide or virus stressing honey bees, and affecting their health, but exposure to a complex web of multiple interacting stressors encountered while at work pollinating crops, new research from York University has found......»»
Arboviruses, mosquitoes and potential hosts tracked in real time in São Paulo city
The technology used to sequence SARS-CoV-2 at record speed early in the COVID-19 pandemic has been successfully tested as a technique to monitor arboviruses and diseases transmitted mainly by mosquitoes......»»
Scientists discover new phage resistance mechanism in phage-bacterial arms race
One of the most abundant and deadliest organisms on Earth is a virus called a bacteriophage (phage). These predators have lethal precision against their targets—not humans, but bacteria. Different phages have evolved to target different bacteria an.....»»
Scientists report that buffer and pH strongly affect the phase separation of SARS-CoV-2 N protein
In a new paper published in Molecular Biology of the Cell, the Allain lab (IBC) reported that the phase separation of the SARS-CoV-2 N protein strongly depends on the chosen buffer and pH. For example, the protonation of a single histidine side chain.....»»

Must mRNA be cloaked in a lipid coat to serve as a vaccine?
The Uchida Laboratory of Innovation Center of NanoMedicine has demonstrated that intradermal administration of mRNA alone (naked mRNA) without protection by nanoparticles induced robust vaccination against SARS CoV-2, a virus causing COVID-19, in mic.....»»
Researchers explain how green algae and bacteria together contribute to climate protection
A research team at Friedrich Schiller University Jena, Germany has now found a bacterium that forms a team with a green alga. Both microorganisms support each other in their growth. Additionally, the bacterium helps the microalga to neutralize the to.....»»
Tracking the virus behind India"s lumpy skin cattle crisis
In May 2022, cattle across India began dying of a mysterious illness. Since then, about 1,00,000 cows have lost their lives to a devastating outbreak of what scientists have identified as lumpy skin disease. The outbreak has severely affected India's.....»»
New York City owl Flaco was exposed to pigeon virus and rat poison before death, tests show
New York City's celebrity owl Flaco was suffering from a severe pigeon-borne illness and high levels of rat poison when he crashed into a building and died last month, officials at the Bronx Zoo said Monday......»»
Bird flu is causing thousands of seal deaths. Scientists aren"t sure how to slow it down
Avian influenza is killing tens of thousands of seals and sea lions in different corners of the world, disrupting ecosystems and flummoxing scientists who don't see a clear way to slow the devastating virus......»»
Nanoparticles target multiple COVID variants through the twist in the spike protein
Teardrop-shaped particles designed to inactivate multiple strains of the SARS-CoV-2 virus could one day complement existing treatments for COVID-19, according to a new study led by researchers at the University of Michigan and Jiangnan University in.....»»
Researchers use an edible blue-green algae to protect honey bees against viruses
Scientists at the United States Department of Agriculture (USDA)'s Agricultural Research Service (ARS) have developed an edible antiviral treatment that can be used to protect honey bees against deformed wing virus (DWV) and other viruses, according.....»»
Ebola: Scientists reveal a new way it replicates
Scientists in Canada and the U.S. have discovered a new way in which Ebola—an often deadly virus affecting people mostly in sub-Saharan Africa—reproduces in the body......»»
In vivo production of CAR-T cells using virus-mimetic fusogenic nanovesicles
Chimeric antigen receptors (CARs) are synthesized membrane proteins that enable lymphocytes to recognize and respond to the specific antigens of target cells. Despite the impressive efficacy of CAR-T cell therapy in treating B-cell lymphoma or leukem.....»»
New bioengineered protein design shows promise in fighting COVID-19
In the wake of the COVID-19 pandemic, scientists have been racing to develop effective treatments and preventatives against the virus. A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus re.....»»
Early experiments show Ebola-fighting potential of engineered bacteria
Since its 1976 emergence in Africa, the Ebola virus has proven an especially lethal contagion, killing roughly 50% of the people who contract it. The 2019 FDA approval of a vaccine, combined with the subsequent development of two antibody-based drugs.....»»
Researchers reveal how a virus hijacks insect sperm: May help control disease vectors and pests
A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria and virus......»»
First atom-level structure of packaged viral genome reveals new properties and dynamics
