NewsStudy explains why virus causing cold sores does not spread to devastating brain infection
Researchers have discovered a previously unknown defence mechanism in the body that is the reason why herpes infection causes a serious and potentially fatal brain inflammation in only one out of 250,000 cases.

NewsNew study highlights scale and impact of long COVID
A wide range of biological mechanisms are involved in long Covid, including persistence of the original virus in the body, disruption of the normal immune response, and microscopic blood clotting, even in some people who had only mild initial infections.

NewsCoinfecting viruses impede each other’s ability to enter cells
Scientists researching phage infection at the level of a single cell investigated whether the number of infecting phages that bind to the bacterial surface corresponds to the amount of viral genetic material that is injected into the cell.

NewsNovel nanosensing technique offers quality control of viral vectors in gene therapy
Researchers report a novel nanosensing technique to measure viral vector characteristics, measuring the ionic current that flows through a nanopore opening when a voltage differential is applied to a solution containing adeno-associated virus.

NewsWhat 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 study reveals.

NewsMouse study reveals how fetal brain impacted when mother fights severe flu
A bad case of the flu during pregnancy can increase the risk for fetal neurodevelopmental disorders such as schizophrenia and autism spectrum disorder. But it’s not the virus itself doing the damage; it’s the mother’s immune response.
