When I was a kid, the word on the playground was that holding in a sneeze would make your eyeballs pop out of your head.

Face shields offer no protection against coronavirus if an infected person nearby sneezes without a mask on, a study shows. Researchers used computer models to visualise the spread of droplets around a face shield ejected by a human sneeze from 3ft (1m) away. It reveals'vortex rings' produced by the sneeze carry infectious particles to the face shield in less than a second and stick to the edges of the plastic. Researchers say if the timing of this wave of coronavirus particles coincides with the face shield wearer breathing in, the person can become infected. Wearing a face mask has a negative impact on our ability to communicate with others, according to a new survey.

A new website will help users stop unconsciously touching their faces by monitoring them through their web cams and playing a loud'NO!' whenever they reach for their faces, one of the most common ways of transmitting the Covid-19 virus. The site, simply called DoNotTouchYourFace.com, was built to run in the background as users go about their normal workdays. Before starting a session, it will ask for access to the web cam and then take a recording of the user sitting still for a few seconds as a baseline. The new website DoNotTouchYourFace.com will watch users through their computer web cams and play a loud'NO!' recording whenever it detects them reaching for their face Then users will be asked to touch their face in as many different ways as they can imagine--rubbing their eyes, cupping their chin, scratching their nose, and everything in between--according to a report in Vice. A machine learning tool built into the site, TensorFlow.js, will then analyze the footage to identify specific movements that will trigger its loud warning sound. Whenever it identifies a user reaching to touch their face, a recording of a loud'NO!' will automatically play, along with a popup notification saying, 'You touched your face.'
