Just as only the jester can tell the King the truth, satire performs a vital function in democratic society by using humor to broach taboo subjects, especially in times of crisis, according to a book by Penn State researchers.

Giving employees more control over their work schedules may help curb sleep deficiency, according to health researchers.

Children obtain better and more age-appropriate sleep in the presence of household rules and regular sleep-wake routines, according to sleep researchers.

With endocrine-disrupting compounds affecting fish populations in rivers as close as Pennsylvania's Susquehanna and as far away as Israel's Jordan, a new research study shows that soils can filter out and break down at least some of these emerging contaminants. The results suggest that water pollution can be diminished by spraying treated wastewater on land rather than discharging it directly into streams, according to researchers in Penn State's College of Agricultural Sciences.

People may have to "turn on" their memories in order to remember even the simplest details of an experience, according to Penn State psychologists. This finding, which has been named "attribute amnesia," indicates that memory is far more selective than previously thought.

Melting of glacial ice will probably raise the sea level around the globe, but how fast this melting will happen is uncertain. Greenland is especially pivotal in the study of melting ice sheets and rising sea levels because it experiences 50 percent more warming than the global average. In the case of the Greenland Ice Sheet, the more temperatures increase, the faster the ice will melt, according to computer model experiments by Penn State geoscientists.

Children whose parents participated in a prenatal program aimed at enhancing couples' co-parenting relationship were better adjusted at age seven than children whose parents were assigned to a control group, according to Penn State researchers.
