Virus

Scientists are again on high alert, as whole genome sequencing of the H5N1 virus has revealed that it is capable of multidirectional infections across species. While human risk is low, it's a step forward for the pathogen in this biological arm's race.

A twice-a-year injectable drug has been shown to be 100% effective in preventing the spread of HIV, according to the first data from a clinical trial. If approved, the drug offers another preventive option and puts us a step closer to eradicating HIV.

A group of volunteers in the UK let scientists put the SARS-CoV-2 virus up their noses for research investigating why some of us naturally avoid getting COVID-19. This first-of-its-kind study opens the door to better vaccines and treatments.

Imagine a world in which we never catch the flu, have no need for vaccines and can wipe out the virus if an infection has taken hold. A super-effective molecule that stops influenza from even entering our bodies stands to revolutionize how we treat flu.

Carbon dioxide is key to how long airborne viruses hang around in the air and, therefore, their likelihood of spreading. Opening a window may be a more scientific way to avoid the spread of respiratory viruses than first anticipated.

Inflammation from a viral infection has traditionally been thought to cause acute myocarditis, which can lead to fatal heart arrhythmias in healthy young adults. Now, it seems it's something else that damages heart cells before inflammation kicks in.

Ever since SARS-CoV-2 emerged, the virus has been known for its novel effects on the brain. But exactly how is it causing these symptoms? A new study suggests that the answer lies in the way our vagus nerve talks to the brain.

Infection with the virus that’s the main cause of cold sores may double a person’s risk of developing dementia. Adding to growing evidence of a link between the herpes virus and dementia, the findings in a new study may lead to new vaccines.

Our bodies are home to trillions of microbes, including bacteria, viruses, fungi, and a whole host of others. Now, Stanford scientists have discovered an entirely new class of biological entities inside us, which they’ve ominously named “Obelisks.”

Researchers developed a nanospiked surface that was 96% effective in destroying a common virus responsible for causing respiratory illnesses in children. The technology could safeguard researchers, health workers and patients from viral spread.

As recent history proves, airborne respiratory infections are not to be trifled with. Now, a new sprayable coating applied to standard air filters might give us a leg up in the war against the pathogens that cause these diseases.

Bacteria often go dormant to avoid being wiped out by antibiotics, which makes treatment difficult. Now scientists have discovered a virus that can attack these sleeping bugs, clearing out infections effectively when paired with drugs.
