• You Don’t Need Single-Use Plastic Bags. You Need a Mask

    Over the past few months, evidence has mounted that the virus’s primary mode of transmission is through the air. One study in March found the virus on air vent blades in a Covid-19 patient’s room in Singapore. Another the same month showed that infectious particles could float in lab-generated aerosols—tiny bits of liquid smaller than 5 microns—for up to three hours. Singing or talking loudly could even propel coronavirus-laced aerosols: In May, the CDC reported that following a two-and-a-half-hour choir practice, 32 people tested positive for Covid-19.

    It’s equipped with a touchscreen and other various hardware components to automatically detect what items you’re placing inside and even how many of those items you’ve picked off the shelf. When you’re done shopping, you’re allowed to take the cart through a special lane that checks you out digitally without requiring a human cashier to ring you up.
