Designer nanoparticles destroy a broad array of viruses

Viral infections kill millions of people worldwide every year, but currently available antiviral drugs are limited in that they mostly act against one or a small handful of related viruses. A few broad-spectrum drugs that ...

Targeting a single protein might treat a broad range of viruses

Most drugs that fight viruses are designed to target individual pathogens. But scientists at The Rockefeller University have identified a protein that a broad range of viruses require to spread within a host—a discovery ...

Gene increases the severity of common colds

Researchers funded by the Swiss National Science Foundation (SNSF) have discovered mutations that worsen respiratory infections among children. Their study explain the mechanism involved.

New lung 'organoids' in a dish mimic features of full-size lung

New lung "organoids"—tiny 3-D structures that mimic features of a full-sized lung—have been created from human pluripotent stem cells by researchers at Columbia University Medical Center (CUMC). The team used the organoids ...

Seeing viruses by both light and electron microscopy

Advances in both light and electron microscopy are improving scientists' ability to visualize viruses such as HIV, respiratory syncytial virus (RSV), measles, influenza, and Zika in their native states. Researchers from Emory ...

Imaging technology could unlock mysteries of a childhood disease

By the time they're two, most children have had respiratory syncytial virus (RSV) and suffered symptoms no worse than a bad cold. But for some children, especially premature babies and those with underlying health conditions, ...

Prevalence of colds and pneumonia in cows can be controlled

Respiratory diseases in cattle are a great threat to animal welfare and lead to financial losses in the cattle industry. The bovine respiratory syncytial virus (BRSV) is one of the main causes of respiratory disease in cattle. ...

Researchers strike gold with nanotech vaccine

Scientists in the US have developed a novel vaccination method that uses tiny gold particles to mimic a virus and carry specific proteins to the body's specialist immune cells.
