Fighting mutant influenza

Public Release: 24-Oct-2018 American Chemical Society Another flu season is here, which means another chance for viruses to mutate. Already, most influenza A viruses contain a mutation that confers resistance against one class of antiviral medications, and the bugs are steadily gaining resistance against another class. Scientists report […]

Amyloid beta protein protects brain from herpes infection by entrapping viral particles

Public Release: 5-Jul-2018 Chronic viral infection could induce overproduction of Alzheimer’s-disease-associated protein and cause damaging inflammation Massachusetts General Hospital A Massachusetts General Hospital (MGH) study has found the mechanism by which amyloid beta (A-beta) – the protein deposited into plaques in the brains of patients with Alzheimer’s disease […]

Genes found only in humans influence brain size

Rats sniff out TB in children

Public Release: 9-Apr-2018   Research shows that rats can detect tuberculosis in children with higher accuracy than standard microscopy tests Springer Rats are able to detect whether a child has tuberculosis (TB), and are much more successful at doing this than a commonly used basic microscopy test. These […]

Ancient origins of viruses discovered

Toothpaste shown to speed enamel erosion?

  Enamel surface loss (SL) after each cycle, for anti-erosive toothpastes (light grey lines represent the control groups). Public Release: 13-Mar-2018 Toothpaste alone does not prevent dental erosion or hypersensitivity An analysis of nine toothpastes found that none of them protects enamel or prevents erosive wear. Specialists stress […]
