Does ‘green energy’ have hidden health and environmental costs?

Production of electricity is responsible for about a quarter of global greenhouse gas emissions, and demand is poised to rise as underserved populations connect to the grid, and electronics and electric vehicles proliferate. So stopping global warming will require a transformation of electricity production. But it is important to avoid various environmental pitfalls in this transition, researchers say.

Elevated stress levels among Norway’s youngest in childcare

Researchers measured the stress hormone cortisol in 112 toddlers from 85 different childcare centres in six municipalities, approximately five months after they started attending. Children with the longest childcare days (8-9 hours) showed an increase in cortisol during the day.

Support, comfort from online weigh-loss group

Online weight loss forums protect participants from public fat shaming, and offer them a place to speak out without being confronted by normal-weight individuals, medical science or the authorities.

“Virtual human” unlocks key mechanisms of high blood pressure

Scientists regularly use computer models to understand complex problems, from predicting the weather to designing boats and automobiles. Now they are also using this approach to better understand the human body — including the causes behind high blood pressure.
