Eureka! How distractions facilitate creative problem-solving

According to psychologists from the University of Toronto and the Radboud University Nijmegen, distractions may be helpful in coming up with creative solutions to a certain problem, but must be followed by a period of conscious thought to ensure that we are aware of those solutions and can apply them. Likewise, while distractions are more useful in solving difficult problems, it may be better to stay focused on finding the solution when confronted with easier problems.

From mothballs to mobilization: Taking the salt out of sea water

The United Nations estimates that 1.1 billion people across the globe lack access to sustainable, clean drinking water. How can science help provide more drinkable water for a growing population on an Earth with limited fresh surface-water and groundwater resources? David Kreamer, University of Nevada, says that desalinization — removing salt from ocean water to create fresh water — is a practical way to meet the growing human need.

During exercise, the human brain shifts into high gear on ‘alternative energy…

A study published in the October 2008 print issue of the FASEB Journal, shows the brain, just like muscles, works harder during strenuous exercise and is fueled by lactate, rather than glucose. This helps explain why the brain is able to work properly when the body’s demands for fuel and oxygen are highest.

Scientists discover why a mother’s high-fat diet contributes to obesity in he…

A new article published online in The FASEB Journal (http://www.fasebj.org) suggests that pregnant women should think twice about high-fat foods. Scientists found that female mice fed high-fat diets were more likely to have oversized offspring (a risk factor for overweight and obesity) because fat causes the placenta to go into “overdrive” by providing too many nutrients to the fetus. This also suggests the reverse may be true — high fat diets may help prevent undersized babies.
