Men and women choose partners according to different criteria. These are the same almost all over the world and have remained unchanged in the last 30 years, according to a new survey of 14 000 people.
Hip fractures have higher mortality rates if patients are discharged early because the hospital needs the space and capacity.
Boys need to burn for something to succeed. Maybe that’s why they often do less well at school than girls.
Children’s health declines the longer they live in refugee camps. Many adults are also struggling, with seven out of ten feeling like they have no future.
Children with ADHD play more video games than other kids do, but gaming does not cause or worsen the condition. Nor do electronic games cause anxiety or depression.
People who followed researchers’ motivational posts on Instagram got more enjoyment out of their training sessions. Just a couple of minutes over the course of four weeks was enough to make a difference.
If your drinking water is contaminated, you’d no doubt like to find out where the pollution comes from. Researchers are working to make this easier.
From the press coverage, you might expect only wasted time and projects built over budget when the government invests in roads, buildings and other large projects. But the state — in Norway, anyway — doesn’t do a bad job after all.
Do you have poor motor skills or struggle to read, write or solve math problems? Maybe it’s really because of how your brain interprets what it sees.
The FINDRISC questionnaire has been used extensively to predict a person’s degree of risk for getting type 2 diabetes, but new findings show that it does not adequately identify the most vulnerable individuals.
