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.

The past few months have been very arduous and challenging due to the COVID-19 crisis. All the economies have been squashed due to the lockdown imposed by various countries. All the scientists are striving hard to find the vaccine for the virus. The engineers, research scientists, technicians, and many more young professionals have invented hardware and software products to stop the spread. All of this has been possible just because of digital technology.

Amazon is pivoting resources and workers typically devoted to its drone division to make and sell face shields that help protect people against COVID-19. According to Amazon, it will sell the face shields'at-cost' meaning it won't make a profit off of them, and says it will announce the selling price for buyers'in the next few weeks.' For now it says that initiative will prioritize selling the shields to frontline workers but the company plans to open up sales to the public in the near future. Among the advantages of making masks themselves, according to Amazon, is a lower end cost to customers. Amazon plans to sell the face shields at cost, meaning the company won't be making a profit.

Health care workers are not the only unwilling essential services frontline workers at increased risk of COVID-19. According to the Washington Post on April 12, "At least 41 grocery workers have died of the coronavirus and thousands more have tested positive in recent weeks". At the same time, grocery stores are seeing a surge in demand and are currently hiring. The food industry is also seeing increasing adoption of robots in both the back end supply chain and in the food retail and food service sectors. "Grocery workers are risking their safety, often for poverty-level wages, so the rest of us can shelter in place," said John Logan, director of labor and employment studies at San Francisco State University. "The only way the rest of us are able to stay home is because they're willing to go to work."

Designers, engineers and programmers have heard the klaxon call. The last few weeks have seen a wave of ingenuity unleashed, with both garden-shed tinkerers and high-tech manufacturers scrambling to develop things that will combat the spread of Covid-19. Many of their innovations raise as many questions as they answer, though. Could 3D printing now finally come into its own, with access to open-source, downloadable designs for medical parts? If so, will intellectual property infringements be waived, or will altruistic hacktivists still face costly lawsuits?
