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.....»»
What shapes a virus"s pandemic potential? SARS-CoV-2 relatives yield clues
Two of the closest known relatives to SARS-CoV-2—a pair of bat coronaviruses discovered by researchers in Laos—may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new Yale study reveals......»»
Virus that causes COVID-19 is widespread in wildlife, scientists find
SARS-CoV-2, the virus responsible for COVID-19, is widespread among wildlife species, according to Virginia Tech research published July 29, 2024 in Nature Communications. The virus was detected in six common backyard species, and antibodies indicati.....»»

Study: Nanoparticle vaccines enhance cross-protection against influenza viruses
To offer cross-protection against diverse influenza virus variants, nanoparticle vaccines can produce pivotal cellular and mucosal immune responses that enhance vaccine efficacy and broaden protection, according to a study by researchers in the Insti.....»»
Pasteurization Kills Bird Flu Virus in Milk, New Studies Confirm
Flash pasteurization destroyed H5N1 viral particles that were highly concentrated in raw milk, confirming that standard techniques can keep dairy products safe from bird flu.....»»
How Some People’s Body Resists Getting COVID
When scientists exposed people to the virus that causes COVID, only a subset got sick. Studying them could offer clues to immunity.....»»
Team pioneers a "one-pot platform" to promptly produce mRNA delivery particles
Imagine a scenario where a skilled hacker must upload critical software to update a central server and thwart a potentially lethal virus from wreaking havoc across a vast computer network. The programmer, armed with the lifesaving code, must navigate.....»»
Receptors make dairy cows a prime target for influenza, team finds
As highly pathogenic avian influenza has spread in dairy herds across the U.S., the virus is being detected in raw milk. A new study by a broad team of researchers at Iowa State University's College of Veterinary Medicine helps explain why......»»
"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......»»
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.....»»
US reports fourth human case of bird flu linked to cows
US officials on Wednesday reported the country's fourth human case of bird flu linked to the current outbreak of the virus in dairy cattle......»»
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.....»»
A new way to see viruses in action: Super-resolution microscopy provides a nano-scale look
A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced microscopy techniques, the researchers produced what m.....»»
Novel virus identified in zebrafish from the pet trade causes disease in laboratory fish
Zebrafish in the pet trade are asymptomatic carriers of previously undescribed microbes, including a novel virus that causes hemorrhaging in infected laboratory fish, Marlen Rice from the University of Utah, US, and colleagues report in the open-acce.....»»
New modified CRISPR protein can fit inside virus used for gene therapy
Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells. Hongjian Wang and colleagues a.....»»
US dairy cows are tip of the iceberg as bird flu spreads in mammals globally, says ecologist
Health authorities are working to gather information on the spread of the H5N1 virus, or bird flu, in U.S. dairy cows—the first confirmation of the virus in cattle......»»
