Why you might want to start wearing better masks — even outdoors – CBC.ca

Published

 on


The spread of more contagious coronavirus variants in Canada amid already high levels of COVID-19 makes it a critical time to think about the masks we wear. 

Whether that means finding better quality masks, doubling up on masks, or wearing them in settings we wouldn’t normally think to, experts say it’s time we step up our game.

The variants first identified in South Africa and the U.K are spreading in Canada, in some cases with no known link to travel, and have already led to devastating outbreaks in long-term care homes.

The variant discovered in the U.K., known as B117, is estimated to be at least 56 per cent more transmissible and potentially more deadly than the original coronavirus strain.

But even as COVID-19 case numbers show early signs of slowing down in Canada, experts say it’s becoming more important than ever to lower our risk of exposure as much as possible to prevent variants from taking hold here. 

“The floodwaters are receding right now, but it’s still very, very dangerous,” said Erin Bromage, a biology professor and immunologist at the University of Massachusetts, Dartmouth who studies infectious diseases.

“If [B117] does pop up as the dominant variant here, we are going to need to really up our game in regards to masks, in regards to … how many contacts we have in a day, because it definitely appears to have an upper hand.” 

‘Time to step it up’ with masks

Canada currently recommends the use of three-layer non-medical masks with a filter layer to prevent the spread of the virus, but has not updated its recommendations since November, before the emergence of new variants. 

Dr. Zain Chagla, an infectious diseases physician at St. Joseph’s Healthcare Hamilton, said that while three-layer non-medical masks are a good “minimum standard,” Canadians should opt for masks that offer better protection whenever possible.

Those include surgical masks, which are a step below N95 or KN95 masks. They come in three different filtration levels determined by the American Society for Testing and Materials (ASTM).

“When I go to the grocery store now, I wear my very best mask,” said Linsey Marr, one of the top aerosol scientists in the world and an expert on the airborne transmission of viruses at Virginia Tech. “Before I was wearing an OK mask that was comfortable and easy.”

She said a cloth mask can “easily filter out half of particles, maybe more, but we’re at the point where we need better performance.” 

Bromage said he changed his approach to masks several months ago when COVID-19 cases started to spike in many parts of North America. That’s when he ditched common cloth masks for surgical masks, he said.

Bromage said Level 3 ASTM surgical masks, those that are used at dental clinics, for example, offer both a better level of protection and a better quality fit.

“The most important part is you’ve got to make sure your breath actually goes through the material,” he said.

“You really should see the mask expand and then collapse and expand and collapse with each breath that you take. That’s a good indication that what you’re breathing is actually going through the material.” 

Double-masking and other tips

Bromage said a tight-fitting mask is more important than ever due to the emergence of variants, which is why it’s becoming more common to see people wearing two masks at the same time.

“It’s not that double-masking provides extra protection if the mask was fitting well,” he said. “Double-masking helps the mask that is closest to your skin fit more snugly, meaning more air goes through that mask.”

If you’re already wearing a high-quality mask that fits well, with air going through the material rather than out the sides, Bromage said there’s really no extra benefit in throwing an extra mask on top.

He recommends looking at yourself in the mirror before you go out to make sure your mask isn’t too loose fitting, which could put you at heightened risk of exposure in situations such as in-store shopping. 

“I really want people to look at them and think, is all the air going through the material? And if it’s not, work out a way to do that,” he said. “And that may be putting a second mask on or finding a different mask that fits their face.” 

Outdoors not without risk

Coronavirus variants can also change the level of risk we face in situations that are typically more safe, such as being outdoors. 

Places such as San Francisco and New Brunswick have mandated outdoor mask use, and Toronto and Ottawa recently announced they now require face masks for outdoor activities such as skating.

“The risk is much lower outdoors than indoors, but with the new variants, we should be more careful outdoors as well as indoors,” said Marr.

“The times we need to be paying attention to it is if there are a lot of people around at a sporting event, or in a crowded park, or if you’re out walking or running and you’re passing by several people per minute, because all those little exposures can add up over time.”

Bromage said he gets concerned when he sees a group of people huddling together outdoors without moving around.

“The closer you are outdoors, the much more risky it is,” he said. 

While not common, there have been cases of outdoor transmission of COVID-19 in Canada.  

An outdoor 40-person barbecue at a park in Ottawa this summer led to 105 people being exposed and two testing positive, while a “heated conversation” in B.C. caused an infection. 

B.C. Provincial Health Officer Dr. Bonnie Henry told CBC News there have been several outdoor transmission events between spectators “clustering and talking with each other” during soccer games, and during wedding receptions where groups of people crowded together under tents.

“Again it comes down to being in close contact, without a mask, talking loudly or sharing food and drinks that makes it risky even outside,” Henry said.  

She said B.C. has not seen transmission from brief outdoor encounters, waiting in line outside or at outdoor picnics where people maintain a reasonable distance and wear masks when close for short periods of time.

Chagla said standing six-feet apart while wearing masks is a responsible way to interact with others outdoors.

“There are ways to do things outdoors safely, even in the context of the variant,” said Chagla. “You don’t want outside to be a free pass, but you also want to use it for what it is, to let people see each other and have contact with humanity, too.”

Bromage said that while the risk of exposure outdoors is less than indoors, the risk of both is higher due to the emergence of coronavirus variants.

“It’s really time that people think about upping their game just in general,” he said.

“Because if we are going to get a new wave from this variant, and it’s already going to build off a very high level of infection that we already have, we need to do better to keep it out of our lives.”

Forged by friendship, this year's Stampede boots pay tribute to Stoney Nakoda iconography – MSN

Published

 on


If not for Duane Mark and Lloyd Templeton’s budding friendship, this year’s Calgary Stampede boot design would have never existed.

While the boot was only constructed in recent months, the process began when Templeton, a Calgary-raised artist in his early 20s, approached Mark with a request to use images of the Stoney Nakoda teepee-holder and educator for artwork he was preparing for the Calgary Stampede.

300x250x1

The two clicked from the get-go. By November, after hours together, Templeton’s piece featuring Mark — dressed in full regalia standing in the foreground of the Calgary Tower among a diverse group of parade participants — was chosen as the 2024 Stampede poster artwork.

On Thursday, Templeton’s art was unveiled as the design for this year’s Stampede boot — now the second product of their friendship that’s been produced for this year’s 10-day rodeo and fair.

“What comes to mind is the growth of a young man named Lloyd,” Mark said, when asked what he sees in this year’s boot design.

The artwork on the exterior reflects key Stoney Nakoda First Nation and Treaty 7 iconography, Templeton said at Thursday’s unveiling. Stitchings of Alberta’s mountain range and the golden eagle flying through a rising sun — two important symbols for the First Nation’s culture — line the outside of the boot.

The boot’s interior has the words Oyadé Gichiyabi, Ahogichopabi Îyûhabith inscribed, which roughly translates in Stoney language to “be empowered to foster peace and respect,” which was selected at Mark’s recommendation.

A recent graduate from the Alberta University of the Arts, Templeton is becoming a household name in Calgary’s arts community at a pace that’s not lost on him.

“Just last year I was making school projects, and a year later, there’s going to be people wearing my art. That’s nuts,” he said.

Working in three dimensions was a new challenge for Templeton. To start, he would tape paper to the back of the boot to get a feel for the shapes he needed to produce. He then drew the designs by pencil, scanned them into his computer and produced it into a special file that allowed it to be etched by laser onto the boots.

“My poster was oil paint, a very traditional process,” he said. “I was kind of making it up on the go to see what worked. I liked the challenge of that.”

Margaret Holloway, the Stampede’s 2024 First Nations Princess who also provided input on the boot design, said she was “breathtaken, speechless” when she first saw the design. Breaking from tradition, this year’s design will be available on five different shades of boot. Alberta Boot normally creates one special boot for each Stampede.

The 22-year-old jingle dancer is the first person from Stoney Nakoda to be named First Nations Princess in more than 20 years.

Holloway’s family teepee at the Elbow River Camp has three large eagles on it, she said.

“Back home, we see the eagles fly and we feel blessed by their presence, and we feel amazed just by their beauty of soaring in the skies. To see that on this year’s Stampede boot was absolutely unbelievable.”

With their latest creation publicly revealed, Templeton and Mark’s friendship will extend far past their artistic collaboration.

“He’s the coolest dude. We have a lot in common — a good sense of humour, listen to the same music and movies. We make a lot of the same jokes,” Templeton said.

Mark said he’s watched the young artist grow and mature in front of his eyes. Over the past year they’ve discussed “deep Indigenous philosophy,” which Templeton has evidently absorbed into his own life, he said.

“We became the best of friends and will continue to be the best of friends,” Mark said.

Huawei's new Kirin 9010 brings minor CPU improvements – GSMArena.com news – GSMArena.com

Published

 on


Huawei announced the Pura 70 series today, and once again offered no details regarding the chipsets. However, early benchrmarks confirmed they feature a new platform called Kirin 9010, which has an 8-core CPU, identified by apps as 12-core unit due to hyperthreading.

Hyperthreading is nothing new in the chipset industry, as the Taishan cores have been supporting the technology for some time; it has been part of the Kirin 9000s and now is a part of the 9010 as well.

First Geekbench results revealed a minor improvement in raw performance, coming from slightly faster core speeds. The numbers show improvement single digit percentage improvements in both single core and multi core tests.

'Kingdom Come: Deliverance II' Revealed In Epic New Trailer And It Looks Incredible – Forbes

Published

 on


“You can save the world, or you can help punish it for its sins.” That’s the crux of Warhorse Studio’s “behemoth” of a sequel to 2018’s Kingdom Come: Deliverance. The sequel, which is slated for release later this year on PC, Xbox Series X|S and PS5 will be bigger, more fun, filled with adventure and more diverse thanks to its setting in the 15th century Bohemian city of Kuttenberg a city that creative director Daniel Vavra says is “really big, it’s even too big in my opinion.”

New weapons like the crossbow and primitive firearms will also make their debut in the continued story of the squire Henry (Tom McKay) and the knight he accompanies, Hans Capon (Luke Dale) as they leave the country behind.

Here’s the trailer, which features gameplay, cinematics and discussion from the actors and developers. Be sure to watch until the end to see the bit about the music. A full choir and orchestra in a beautiful Eastern European cathedral? Just gorgeous.

“What we are making now is what it was supposed to be in the beginning, but we weren’t able to do it because we didn’t have enough resources and experiences and all that stuff,” Vavra says in the video. “We’ve proven the concept works, so now we can take it to another level, which is what we always wanted.”

“This is a behemoth of a game in comparison to the first. In my opinion I think it’s got so much more energy and pace and adventure and action and fun and trial and tribulation and everything you can want,” McKay says in the video.

The game will be “much bigger in scope” with a more in-depth story and a world roughly twice the size of the first. The story has evolved from a small-scale conflict to one about “the problem with kings,” Vavra says.

);
)();

Kingdom Come Deliverance II, like the first game, is not a fantasy RPG like Skyrim or The Witcher, but one that attempts to create a historically accurate world down to the weapons, costumes, locations and people. There are no magicians or dragons or elves here—but there will be plenty of adventure, exploration and knight errantry.

Pretty exciting!
