According to Columbia University researchers, virginity pledge programs increase pledge-takers’ risk for STIs and pregnancy. The study concluded that 88 percent of pledge-takers initiated sex prior to marriage even though some delayed sex for a while. Rates of STIs among pledge-takers and non-pledgers were similar, even though pledge-takers initiated sex later. Pledge-takers were less likely to seek STI testing and less likely to use contraception when they did have sexIn a detailed genetic kinship study, an international team is the first to reveal that just like human societies, beluga whales appear to value culture and their ancestral roots and family ties. They have demonstrated that related whales returned to the same locations year after year, and decade after decade. Not only do these whales know where to go and where not to go, they are passing on this information from one generation to the next. Findings from this study also pin down the fundamental structure of the building blocks of beluga whale society and provide compelling evidence that migratory culture is inherited. It further helps maintain demographically discrete populations of beluga whales that can overlap in both time and space. Not only do these whales know where to go and where not to go, they also are passing on this information from one generation to the next.
I think this is cool because whales actually remember their family ties. The have the whole ocean to swim and roam but they decide to stay with their family.
