Exposure to cuticular bacteria can alter host behavior in a funnel-weaving spider.

Contact with environmental microbes are arguably the most common species interaction in which any animal participates. Studies have noted diverse relationships between hosts and resident microbes, which can have strong consequences for host development, physiology, and behavior. Many of these studies focus specifically on pathogens or beneficial microbes, while the benign microbes, of which the majority of bacteria could be described, are often ignored.

Weight-Loss Outcomes from a Pilot Study of African Dance in Older African Americans.

Objective: Obesity is a risk factor for both cognitive and physical impairment in late adulthood. Though the rates of obesity are high in many groups, older African Americans are disproportionately affected. A randomized pilot intervention of African Dance was conducted with 28 African American older adults with obesity (mean age = 68.
