Engineered sandbars don't measure up for nesting plovers
Dams reduce the creation of natural sandbars, which is bad news for birds that depend on them for nesting habitat. More than 200 hectares of engineered sandbars have been built along the Missouri River to address this problem -- but how does this compare to the real thing? A new study takes advantage of a natural experiment created by the region's 2011 floods, demonstrating that engineered habitat doesn't provide the benefits of sandbars created by nature. (2018-01-10)

New study finds artwork is worth 35 percent less when created by 'tortured' artists
The term 'tortured artists' describes some of history's greatest painters, who are credited with creating some of the world's most recognized works of art despite lives that were often characterized as unhappy. But does misery really beget valuable works of art? According to a new study in the INFORMS journal Management Science, personal unhappiness, particularly that experienced in times of bereavement, can actually cause a significant decrease in the value of an artist's work.
