Study tracks sleep patterns of first-time and experienced parents — ScienceDaily

Mothers with multiple children report more fragmented sleep than mothers of a single child, but the number of children in a family doesn’t seem to affect the quality of sleep for fathers, according to a study from McGill University. A total of 111 parents (54 couples and 3 mothers of single-parent families) participated in the […]

Human migration patterns connected to vitamin D deficiencies today

A new study in the Oxford Economic Papers finds that migration flows the last 500 years from high sunlight regions to low sunlight regions influence contemporary health outcomes in destination countries. The researchers here noted that people’s ability to synthesize vitamin D from sunlight declines with skin pigmentation, and that vitamin D deficiency is directly […]

Urban gulls adapt foraging schedule to human activity patterns

Credit: CC0 Public Domain If you’ve ever seen a seagull snatch a pasty or felt their beady eyes on your sandwich in the park, you’d be right to suspect they know exactly when to strike to increase their chances of getting a human snack. A new study by the University of Bristol is the most […]
