People may actively decide to withhold feeling compassion for others when they believe it is more challenging or requires mental effort.
Paternal depression may contribute to adolescent depression and behavioral problems, regardless of whether or not the father and child are genetically related, researchers say.
Researchers have uncovered genetic interactions that modulate variable symptoms associated with ASD.
Flavored e-cigarette tobacco engages the taste system, while non-flavored vaped nicotine triggers the brain's reward system in a similar way observed when people smoke traditional cigarettes.
Cultural, linguistic, and biological diversity are linked, researchers say. The link may be to preserve both natural environments and indigenous populations.
Better quality sleep is linked to improved emotions and fewer stressors the next day, a new study reports.
Among older women, lower levels of hydration were associated with lower scores on tests designed to measure attention, working memory, and motor speed. Researchers also found over-hydration may have a detrimental effect on cognitive function.
Parkinson's patients who increase the number of flavonoid-rich foods they consume as part of their diet have a lower mortality risk than those who don't.

43% of children who experience insomnia continue to experience symptoms of the sleep disorder during adolescence and into adulthood.
Neuroimaging allowed researchers to make some key discoveries about the developing brain. The study revealed male children had overall greater brain volume, but the size of specific brain structures did not differ between sexes, nor did cognitive ability. Additionally, regardless of the sex or size of the child, the ratio between the size of the brain and the volume of cerebrospinal fluid was universal.
