Researchers identify host entry factor for Rift Valley fever virus

Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hundreds of human cases and dozens of deaths.

New map provides a reference to predict which antibodies are effective against SARS-CoV-2

Scientists at La Jolla Institute for Immunology have published a detailed map of where human antibodies bind to SARS-CoV-2, a map that was generated by a global collaboration comparing nearly all leading clinical candidates.

Scientists analyze the molecular machinery of poxviruses at an atomic level

Poxviruses have found a unique way of translating their genes into proteins in the infected organism. A team of researchers from Würzburg shows for the first time how the molecular machinery involved works at an atomic level.

Researchers develop a DNA sensor to target and detect infectious viruses in minutes

A new sensor can detect not only whether a virus is present, but whether it's infectious – an important distinction for containing viral spread.

Combining bacteriophages with antibiotics to treat antibiotic-resistant infections

Mycobacterium abscessus, a relative of the bacteria that cause tuberculosis and leprosy, is responsible for particularly severe damage to human lungs and can be resistant to many standard antibiotics, making infections extremely challenging to treat.

Poor systemic immune responses and elevated MAIT cell activation linked to fatal COVID-19 infections

The mortality rate of COVID-19 patients requiring mechanical ventilation is 30-40%, however, the immunological factors associated with death in critically ill COVID-19 patients are poorly understood.

RIT scientists uncover new information about the way coronavirus attaches to human cells

Rochester Institute of Technology scientists have uncovered new information about the way coronavirus and several of its variants attach to human cells.

Study could help choose the ideal DNA extraction method for microbiome research

Let's face it, we are a results-driven society. Too focused on the outcome, people don't often think about the "how." For instance, did you think about "how" you got to work this morning or did you just get there? In microbiome studies the results are the graphs and the data but the "how," like commuting, is often just part of a routine.

Viruses buried in marsupials' DNA may help protect against future infections

Fossils of ancient viruses are preserved in the genomes of all animals, including humans, and have long been regarded as junk DNA. But are they truly junk, or do they actually serve a useful purpose?

Study credits gut microbiota for the presence of maternal IgA in milk

Maternal antibodies are transmitted through breastfeeding, safeguarding the gastrointestinal tracts of infants from numerous pathogen-caused infections.

Study details replication and immune evasion of Delta SARS-CoV-2 variant

According to scientists, the Delta variant of SARS-CoV-2 has likely spread through its capability to avoid neutralizing antibodies and its heightened infectivity.

Gut bacteria may play a key role in neurological damage of premature infants

Extremely premature infants are at a high risk for brain damage. Researchers at the University of Vienna and the Medical University of Vienna have now found possible targets for the early treatment of such damage outside the brain: Bacteria in the gut of premature infants may play a key role.
