How cannabis use affects brains of male teenagers with high genetic risk for schizophrenia

Professor Tomas Paus: “Our study shows the importance of understanding environmental influences on the developing brain in early life”
Kelly Connelly

Male teens who experiment with cannabis before age 16, and have a high genetic risk for schizophrenia, show a different brain development trajectory than low-risk peers who use cannabis.

The discovery, made from a combined analysis of over 1,500 youth, contributes to a growing body of evidence implicating cannabis use in adolescence and schizophrenia later in life, researchers said.

How bacteria steal our nutrients – and help themselves to dessert

By Heidi Singer and Carolyn Morris

In two studies published this week, University of Toronto scientists take a close look at how harmful bacteria feast on our bodies’ nutrients – with certain proteins pillaging our iron and zinc, and others devouring phosphorylated sweets. 

Why we're smarter than chickens

Researchers at U of T’s Donnelly Centre uncover protein part that controls neuron development

U of T researchers have discovered that a single molecular event in our cells could hold the key to how we evolved to become the smartest creatures on the planet.

The diabetes drug that shows promise for treating childhood brain injury

Using Metformin on young mice had dramatic results, researchers say
Erin Howe

Researchers in Professor Cindi Morshead’s lab have found that metformin can help activate stem cells to make repairs in the brain in a form of childhood brain injury similar to cerebral palsy.  

The study was published in Stem Cell Reports.

Dr. Anthony Feinstein on war, conflict and “why journalism is undoubtedly more dangerous today”

Journalists are now “high-profile targets,” expert says
Jelena Damjanovic

From Syria to Ukraine, frontline journalists give readers first-hand accounts of violence, suffering and hope in conflicts distant and near. But in so doing they challenge their own physical and emotional well-being.

Dr. Anthony Feinstein, a professor at the University of Toronto and a psychiatrist at Sunnybrook Health Sciences Centre, is a world leader on the psychological effects of war on journalists.

How hunger leads to higher health-care costs

Researchers find growing evidence of link between food security and health
Carolyn Morris

People who struggle to put food on the table use health care more – and account for much higher health-care costs – than people with the same income level who don't experience food insecurity, University of Toronto researchers say.

Research shows dramatic link between inflammatory bowel diseases and anxiety disorder

Michael Kennedy

If you have inflammatory bowel disease – such as Crohn’s disease or ulcerative colitis – you are twice as likely to have generalized anxiety disorder as someone who does not have IBD, new research shows.

The findings come in a study published on July 28 by University of Toronto researchers.

How stem cell research and regenerative medicine saved this man's life

Jonathan Furneaux shares his story about the impact of Medicine by Design

U of T to transform regenerative medicine thanks to historic $114-million federal grant

Terry Lavender

The University of Toronto is set to cement its position as one of the world’s leading centres for the design and manufacture of cells, tissues and organs that can be used to treat degenerative disease, thanks to a $114-million grant from the federal government.

Understanding Medicine by Design

The Medicine by Design initiative announced July 28 will establish a leading centre in regenerative medicine at the University of Toronto.

Researchers at the centre will focus on discovering new therapies based on the design and manufacture of molecules, cells, tissues and organs that can be used safely and effectively to treat degenerative diseases.
