The brain is the most complicated object in the universe. This is the story of scientists’ quest to decode it – and read people’s minds

As Elon Musk’s Neuralink begins inserting chips into human brains, we trace the history of ‘mind reading’ technology and assess the potential risks and rewards

What Canadians need to know about West Nile virus, a mosquito-borne infection that can be life-threatening

West Nile virus arrived in North America in 1999 and spread across the continent by 2005. Here’s what you need to know about this mosquito-borne pathogen.

People produce endocannabinoids – similar to compounds found in marijuana – that are critical to many bodily functions

A THC-like substance that occurs naturally in humans and other vertebrates helps maintain immunity, memory, nerve function and more – and research suggests a lack of it can harm health.

La Crosse virus is the second-most common virus in the US spread by mosquitoes – and can cause severe neurological damage in rare cases

Not all cases of La Crosse disease affect the neurological system, but those that do can be severe and sometimes fatal – especially in children.

Brain stimulation can rewire and heal damaged neural connections, but it isn’t clear how – research suggests personalization may be key to more effective therapies

Existing brain connections may influence the effectiveness of neurostimulation. Tailoring treatments to each individual brain could expand the number of conditions brain stimulation can treat.
Exercise spurs the release of the body’s natural cannabinoids, which have myriad benefits for mental health and stress relief. Luca Sage/Stone via Getty Images

The ‘runner’s high’ may result from molecules called cannabinoids – the body’s own version of THC and CBD

A growing body of research points to the body’s natural cannabinoid system as the primary driver behind the runner’s high – and the mental health boost and stress relief following exercise.
