A nuclear arms race could have devastating effects, and working towards nuclear disarmament is becoming more urgent. Shutterstock

Canada could slow the nuclear arms race

The recent nuclear explosions in Russia serve as a reminder of the threat that nuclear weapons pose. Canada is uniquely situated to work toward the elimination of nuclear weapons globally.

Today, and into the future, consulting archival documents increasingly means reading them on a screen. (Shutterstock)

Historians’ archival research looks different in digital age

As our societies lose paper trails and increasingly rely on digital information, historians, and their grasps of context, will become more important than ever.
Currently, stem cell based treatments are still mostly experimental, and while some results are encouraging, several clinical trials have failed. (Shutterstock)

Stem cell treatments: Miracle cures?

Stem cells show much promise, both for testing drugs and for treating disease. But the hype around them has been dangerous, as most treatments are in very experimental stages and can cause harm.
As AI and robotics advance and produce more lifelike sex robots, there is the potential for an increase in gender-based violence. Shutterstock

Could sex robots fuel gender-based violence?

An increasing demand for sex robots is concerning, as there are ethical concerns about a possible related increase in gender-based violence.
