Will wearing two masks better protect me from the virus? AP Illustration/Peter Hamlin
Does wearing two masks provide more protection?
It depends, but it’s possible that doubling up could help in some situations.
The U.S. Centers for Disease Control and Prevention recommends wearing a cloth mask made with two or more layers, and ensuring it covers your nose and mouth. The agency says it should fit snugly so there aren't any gaps at the sides of your face.
Wearing just one mask should be enough for most situations, as long as it fits well and isn't loose, said Dr. David Hamer, an infectious disease expert at Boston University.
“Starting out with a good mask to begin with is going to be key,” Hamer said.
Still, some people might want extra protection if they're at risk for severe illness if infected or will be in situations where they expect to be around others for extended periods, such as on a plane.
One option in scenarios when you want extra protection is to wear a cloth mask as well as a regular surgical mask, said Dr. Monica Gandhi, an infectious disease expert at the University of California, San Francisco.
Gandhi said that combination -- with either mask on top -- could help achieve a similar effect as the N95 mask. She recommended the added protection for people who will be indoors in areas where transmission rates are high — which could reflect the circulation of more contagious variants.
Another option Gandhi and a colleague recommend for situations where you want “maximum” protection: A two-layer cloth mask that has a filter material in between.
With single cloth masks for everyday use, Gandhi noted it's important that they're made of tightly-woven material and have at least two layers, which creates “an obstacle course” that makes it harder for virus-carrying particles to break through.
Amazon plans to launch its first prototype satellites for Project Kuiper, an internet-from-space venture, in 2022. It's the first major step in the e-commerce giant's plan to rival SpaceX by building a network of satellites in space, providing internet to rural, underserved communities around the world. Loren Grush, senior science reporter for the Verge, discusses the project and how it could transform internet access moving forward.
The FDA is assessing whether the Moderna vaccine can cause heart problems in adolescents. Professor Peter Pitts, founder of the Center for Medicine in the Public Interest and former FDA Associate Commissioner, discusses what the FDA is looking into and what it means for the millions of kids yet to be vaccinated.
Pfizer posted an earnings beat in its third quarter, with revenue soaring over 134% thanks to solid Covid-19 vaccine sales. Pfizer also raised its outlook for the full-year, expecting revenue to surpass $80 billion. Peter Andersen, CEO & founder of Andersen Capital Management, joined Cheddar Movers to discuss.

Leaders around the world have come together to discuss plans to bring action towards the Paris Agreement along with solutions on how to solve the evolving climate change crisis at the COP26 Summit. President and CEO of Center for International Environmental Law Carroll Muffett, joined Cheddar to discuss more.
Rachel Cleetus, the policy director and lead economist of the climate and energy program for the Union of Concerned Scientists, joined Cheddar to break down some of the key goals from the COP26 summit and why leaders must focus on the science of climate change instead of getting bogged down by petty politics and the fossil fuel industry. "The main thing they have to do, make sure we're cutting our emissions sharply within this decade because the science shows that we have to cut global emissions in half by 2030 if we're going to meet our goals of averting some of the most catastrophic impacts of climate change," she said.
Coastal cities around the world are grappling with sea level rise. And building a seawall? Not so fast. While a sea wall can be effective in certain scenarios, it can make the effects of sea level rise worse. That’s why municipalities are looking into creative alternatives.
