Psychologist Candice Odgers has studied adolescent mental health for 25 years. She fears the current debate around smartphones obscures some of the biggest issues facing teenagers – from the impact of Covid to the health of their adult caregivers

The quickest way to make being online safer for children and teens would be to kick all adult men off the internet, the Canadian psychologist Candice Odgers believes. Men are the biggest perpetrators of sextortion and most likely to spread misinformation, she says.

Odgers is not recommending this as a policy for governments to adopt: “That would be crazy, right? It would be unfair.” But she is on a drive to puncture the prevailing narrative that the best way to address online harms is a social media ban for teenagers.

The 1930s brought the worst economic collapse in American history. Banks failed, unemployment soared past 20 percent, and most households operated on tight, uncertain budgets. Yet wedding photographs from this decade tell an unexpected story.

In the early 1970s, the Ohio River was both a vital economic artery and a stark reminder of the environmental costs of industrial growth.

Many people think of a traumatic brain injury as an accident that happens suddenly, such as a fall, a car crash, or a sports injury.

Scientists are increasingly discovering that mental health may be influenced by much more than the brain alone. One surprising area of research focuses on the digestive system and the tiny organisms that live inside it. These microorganisms may help shape mood, behavior, and emotional well-being. Depression is one of the most common mental health conditions […]

Flip through any auto parts catalog from the 1970s or 80s and the message becomes clear within seconds: this was an industry that believed a woman in a bikini could sell anything from spark plugs to seat covers.
