A new study on how we use reward information for making choices shows how humans and monkeys adopt their decision-making strategies depending on the uncertainty of information present. The findings challenge one of the most fundamental assumptions in economics, neuroeconomics and choice theory that decision-makers typically evaluate risky options in a multiplicative way when in fact this only applies in a limited case when information about both the magnitude and probability of the reward are known.

The city of Barcelona could prevent 667 premature deaths every year by implementing the proposed "Superblocks" project in its entirety. This result would be achieved mainly as a result of decreased air pollution (NO2), but reductions in traffic noise and mitigation of heat island effects would also be contributing factors. These were some of the conclusions of a recent study published in Environment International, which was carried out by the Barcelona Institute for Global Health (ISGlobal), a centre supported by "la Caixa."

Being good at math relates to better financial and medical outcomes -- unless you don't have confidence in your own abilities with numbers, new research suggests. In two studies, researchers found that the key to success in personal finances and dealing with a complex disease was a match between a person's math abilities and how comfortable and assured he or she felt using those skills.

Emissions from air pollutants are associated with premature mortality. Between 2008 and 2014, air pollution health damage from fine particulate matter exposure fell by 20 percent in the United States. There are four sectors in the U.S. economy that together are responsible for over 75 percent of air pollution damage but contribute less than 20 percent to national GDP: agriculture, utilities, manufacturing and transportation.
