Future infectious diseases: Recent history shows we can never again be complacent about pathogens

Before COVID-19, clean water, antibiotics and vaccines had made us complacent about infectious disease. Infection control can no longer be taken for granted. We must be prepared for future pandemics.

Russian capture of Ukraine’s Chornobyl nuclear plant threatens future research on radioactivity and wildlife

Heavy military vehicles may have kicked up radioactive soil around Chornobyl, and with fighting nearby there’s a danger of harming the concrete shelter containing the radiation of the leaking reactor.
Xenotransplantation is the transplanting of cells, tissues or organs from animals to humans. Pre-clinical trials of organ transplant from pigs have addressed some of the technical barriers. (Shutterstock)

Organ transplants from pigs: Medical miracle or pandemic in the making?

New developments in organ transplants from animals show promise. However, there has been no public engagement about a potential risk. It may streamline a pathway to humans for new zoonotic diseases.

RuPaul’s Drag Race contestant, Maddy Morphosis, sparks conversations about cishet inclusion and queer discomfort

A straight cis-man could have made “herstory” as “America’s Next Drag Superstar.” Drag Race’s inclusion problem botches racialized queer histories, community discomfort and ally participation.

A better post-pandemic future means not giving in to COVID-19 now

After two years of COVID-19, it’s understandable that many people are weary of infection prevention measures. But simply being tired of the pandemic is no reason to let our guard down.
Policy-makers lack an understanding of how to assess research and the quality of that research. We need to do better during the COVID-19 pandemic and during future health crises. (Louis Reed/Unsplash)

5 ways to tackle ignorance about evidence during and after the COVID-19 pandemic

In most countries, ignorance about how to use evidence properly to inform decision-making has led to missteps during the COVID-19 pandemic. Here’s how to do better.

Majority of Canadians disagree with ‘freedom convoy’ on vaccine mandates and lockdowns

Most Canadians support government measures to help control the spread of COVID-19, according to a public opinion study. But they’re growing weary of the pandemic.

Politicizing COVID-19 vaccination efforts has fuelled vaccine hesitancy

The antagonism driven by political interference in COVID-19 vaccination is fuelling hesitancy. Mass vaccination campaigns require public buy-in via trusted health-care providers and community leaders.

Covid longue : une personne infectée sur dix en souffre

On ne sait pas grand-chose de la « Covid longue », notamment qui, quand et à quel point elle frappera, combien de temps il faudra pour s’en remettre, ou si une guérison complète est possible.
Today, teens are often seen as troublesome and difficult. Ancient Roman writers also described adolescence as a period of “hooliganism and debauchery.” (Shutterstock)

Bones and teeth help reveal whether teenagers have always been a source of worry for their parents

Teens across millennia have yearned to explore, try new things and participate in risky behaviours. The key difference, however, seems to be the experience of a rebellion or restlessness.

Answers from COVID experts: How do you talk to family members who aren’t vaccinated? How can the vaccines be safe if they were developed so quickly? Is natural immunity better than being vaccinated?

A panel of experts answer questions about vaccines, omicron and other COVID-related issues in a discussion with The Conversation.

A new approach finds materials that can turn waste heat into electricity

More than two-thirds of the world’s energy is wasted as heat. Thermoelectric materials can convert unwanted heat into electricity, but finding the best ones has been slow.
