Simon Fraser University s International CyberCrime Research Centre (ICCRC) is engaged in a new project to develop artificial intelligence tools to fight COVID-19-related misinformation campaigns on social media.
Throughout the pandemic, anti-science theories on social media that portray COVID-19 as a hoax or downplay the risk of infection have contributed to unnecessary transmission and death. Some research suggests that one-in-three people have encountered false or misleading information about COVID-19 on social media. And while COVID-19 vaccines are rolling out, misinformation on social media still fuels vaccine hesitancy in Canada and resistance to public health measures such as mask wearing.
Herd immunity, or population immunity, is normally considered the point at which enough people are vaccinated or have immune protection from previous infection so that the disease will not spread through the population.
Spiders avoid building webs near European fire ants, their natural predators, by sensing the chemicals they give off in the environment, Simon Fraser University researchers have found.
The findings, published recently in Royal Society Open Science, give us a peek inside the enduring struggle between spiders and ants, and could lead to the development of natural repellents for homeowners worried about unwanted eight-legged guests.
