    An invention to apply plasma to frequently touched items for continuous disinfection could provide a safe and effective, non-chemical way to reduce pathogens on various surfaces such as keypads, escalator handrails and other high-touch surfaces, Princeton Plasma Physics Laboratory (PPPL) inventors say.

    The invention (patent pending) directs cold plasma from different orientations to keep surfaces disinfected without hand sanitizer, sprays, ultraviolet light or other chemical-based solutions.

    For the first time, researchers have directly visualized how speaking produces and expels droplets of saliva into the air. The smallest droplets can be inhaled by other people and are a primary way that respiratory infections like COVID-19 spread from person to person.

    Vaccines are one of the most important tools we have in our defense against infectious diseases, but not everyone responds to vaccination in the same way. Parasites such as worms and viruses change the way a person or animal’s immune system functions, and this can affect their ability to respond to vaccines.

    A Policy Forum article published today in Science shows that an annual investment of $30 billion should be enough to offset the costs of preventing another global pandemic such as COVID-19.

    Thus far, COVID has cost at least $2.6 trillion and may cost 10 times this amount. It is the largest global pandemic in 100 years. Six months after emerging, it has killed over 600,000 people and is having a major impact on the global economy.
