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.
NASA's Perseverance Rover unexpectedly has discovered volcanic rock on the surface of Mars. Scientists initially had thought the rocks were sedimentary in nature.
The deadly tornadoes that devastated Kentucky and five other states last weekend have brought climate change back to forefront of the conversation. Scientists say no single weather event can be pinned to climate change alone, but this December has been unseasonably warm, and warmer temperatures can make extreme weather events more likely. Jana Houser, associate professor of meteorology at Ohio University, joined Cheddar to discuss what role climate change might have played in these deadly tornadoes, and what can be done to prevent severe weather events like this from getting even worse in the future.
Even as tech giant Google implements a vaccination mandate, charging its employees to declare their vaccine status within a time frame or risk dismissal, the federal government is tangled up in the court system trying to impose one of its own. Cindy Cohn, the executive director of the Electronic Frontier Foundation, and Harry Nelson, founder and managing partner of Nelson Hardiman LLP, joined Cheddar to debate the ethics, efficacy, and legality surrounding the issue. While Cohn noted that she thinks the federal mandate might be legally sound, her organization is also concerned with a separate question of privacy. "At EFF what we're most interested in is the digital surveillance that's going along with some of these attempts to try to track and confirm whether people are vaccinated or not," she said.
There is a new way for investors to bet on cannabis - the AdvisorShares Poseidon Dynamic Cannabis ETF targets about 20 of the biggest names in U.S. cannabis. It comes at a time when it's still difficult for investors to access the space. Cheddar News cannabis reporter Chloe Aiello spoke with co-founder and managing director for Poseidon Investment Management, Emily Paxhia.
Joellen Russell, Professor at the University of Arizona, joins Cheddar Climate to discuss how poor academic curricula and misinformation online are hindering efforts to educate children about climate change, as well as how Science Moms is providing resources to moms to help create a safer world for their children.
Another successful spaceflight is in the books for Jeff Bezos' Blue Origin. The company's third human spaceflight blasted off from Van Horn, TX. on Saturday, lasting about ten minutes from takeoff to landing. The crew, which included former NFL star and current GMA host Michael Strahan, traveled to the edge of space and experienced a few minutes of weightlessness before the capsule descended back to earth. Andrew Chanin, CEO of ProcureAM, joined Cheddar's Opening Bell to discuss the significance of the launch.
The U.S. Government is making its first major move toward encouraging nuclear energy in the U.S., as it pushes toward a sustainable future. Scott Waldman, White House reporter for Politico's E&E News joined Cheddar News to break down the developments. "There's definitely an audience for this now since we're looking at the value of nuclear in terms of climate policy," he said, regarding the prospects for bipartisan support.
Google reportedly has announced that its employees must declare their vaccination status by January 18 or face a loss of pay, administrative leave, and eventual termination.
