Study reveals the persistent effects of corruption on trust and voting

A recent study by Bocconi University found that corruption can have a long-lasting effect on trust in democratic institutions. First-time voters who experienced the Mani Pulite investigation in 1994 were more likely to vote for populist parties and express lower institutional trust even 20 years later. The study highlights the need to ...

A toddler’s gut bacteria predict whether they will be overweight at 5 years old

A new study found that the gut microbiota of toddlers at 3.5 years old is predictive of body mass index (BMI) at age 5, with certain types of bacteria associated with a higher or lower risk of obesity. The research also suggests that changes in the gut microbiota begin in early childhood and can influence weight gain later in life.

Room-temperature, solid-state synthesis of high-quality Cs3Cu2I5 thin films

Researchers at Tokyo Institute of Technology have successfully synthesized high-quality Cs3Cu2I5 thin films using a novel solid-state synthesis method. The team discovered that depositing CuI and CsI layers in specific ratios results in distinct local structures containing point defects, leading to highly efficient emissions.
