When supermarkets choose the right strategy for surplus food, they can both reduce food waste and improve their bottom line. An analysis from the University of Copenhagen shows that it is often more profitable to donate surplus food than to throw it away. In many cases, doing so leads to a direct financial gain.

Adopted children who have grown up in more favourable family environments than their siblings are at lower risk of mental health issues, criminality and social problems – benefits that, in some cases, extend to the next generation. These are the findings of a new study of Swedish siblings published in The BMJ.

A large Swedish study published in The BMJ today suggests that an improved early home environment can have lasting positive effects across generations. Children of parents with psychiatric or behavioural issues who were adopted before age 10 into families with better home environments, showed improved adult psychosocial outcomes, including fewer criminal convictions and higher educational achievements, than their unadopted siblings.
