Do masks with antiviral coating offer more protection?

It’s an intriguing idea, but there haven’t been enough rigorous independent studies to establish whether antiviral masks are better at protecting wearers or preventing the spread of the virus.

Their specifics vary, but many antiviral masks are supposed to be made or coated with materials that have extra virus-fighting properties, such as copper.

Websites for several antiviral masks do not provide detailed information about how researchers tested their safety or effectiveness, said Hyo-Jick Choi, a materials science expert at the University of Alberta.

But it usually takes years to design and test new mask technology, said Choi, who is part of a group that has been developing a different type of antiviral mask since before the pandemic.

Masks marketed as being “antiviral” often cost more than N-95 and surgical masks. A single coated mask can cost up to $10; disposable surgical masks and N-95 masks sell at large retailers for between 35 cents and $3 per mask.

Choi said a simpler way to boost the effectiveness of the masks you’re already using is to ensure you’re putting them on, wearing them and taking them off correctly.

And no mask can fully protect wearers, “but almost any mask can help to protect others around the wearers,” said Jiaxing Huang, a professor of materials science and engineering at Northwestern University.

Game on.

Just two weeks after city council approved a referendum on whether to open Winnipeg’s landmark intersection, an official ‘Yes’ campaign in support of tearing down the barriers has formed.

A coalition of downtown business and land owners, planners, architects and advertising and marketing firms — with the support of organizations such as the Exchange District and Downtown BIZ organizations — has taken up the challenge to defend Mayor Brian Bowman’s vision of a barrier-free Portage and Main.

Organizers said the campaign in favour of re-opening the intersection will be funded by an online crowd-sourcing campaign and will open a storefront headquarters in the shadow of the historic intersection. Lawn signs, promotional videos and mass mail will all be part of the drive to remove pedestrian barriers once and for all.

Controlling pace of response path to success

Tim Kist 5 minute read 2:02 AM CDT

WITH the recent collapse of Canada-U.S. trade talks, the economic, political and social changes are coming at business leaders on a daily basis.

While you cannot control the pace of these changes, you can control the pace of response and timing of actions your organization takes. This is a time for thoughtful analysis and careful action, not chasing the latest trends.

Artificial intelligence, for example, can write articles, create images, draft emails and perform seemingly countless other tasks. But is this new tool solving a current business problem?

Successful companies know they must develop a strategy before launching any tactics. Otherwise, the strategy is based on “hope” — and we all know hope is not a strategy.

Kent Kamenz has been the regional director for Slo-Pitch National in Manitoba for more than 20 years. But owing to the province’s never-ending winter, this season will begin later than in any other year he can recall (the 2020 pandemic year not included, of course).

Thanks a lot, Mother Nature.

“Truthfully, we were supposed to have our very first tournament this weekend. Obviously, that was cancelled about three weeks ago because we saw the writing on the wall,” Kamenz told the Free Press.

“So, this weekend and next weekend were supposed to be our first two weekends for tournaments, you know, get the teams out there and get them kind of ready for their leagues. We’ve obviously cancelled those two and now we’ve pushed everything back to May 14 and May 15 for tournaments.

Endometriosis painful, lack of research shameful

Jen Zoratti 7 minute read Tuesday, Mar. 17, 2026

In late 2023, I spent a few weeks in the dark days of winter talking to women about their experiences with endometriosis for a reported feature. I listened as they told me about the labyrinthian, sometimes decades-long quest to get a diagnosis. They told me about being gaslit and dismissed by doctors. One told me about having to get surgery abroad and pay for it out of pocket.

I listened as they raged and cried.

Through my reporting, I learned the cruel facts of this disease.

That endometriosis is a chronic inflammatory disease in which tissue that looks and behaves similarly to the lining of the uterus grows outside the uterus.

WHAT IT IS: Copy Paperis a 2014 textile-based piece by Ontario-born, Winnipeg-based artist Kristin Nelson, currently on view at WAG-Qaumajuq as part of the exhibition Terra Cognita/Incognita.

Of the 125 works in the show — which uses historical and contemporary pieces from WAG-Qaumajuq’s permanent collection to explore how artists have represented the landscape over time and across cultures —probably the most attention-getting are the beautiful paintings of Canada’s lakes, plains, forests and mountains.

So, how does this seemingly modest, somewhat enigmatic work connect to Terra Cognita/Incognita’s larger themes?

WHAT IT’S ABOUT: In the middle of the exhibition, an antique desk holds several objects of beauty and utility, and this is where Copy Paper sneaks in, as something both “cognita and incognita,” known and unknown.
