Older Adults May Be Unreliable Eyewitnesses, Study Shows:

A University of Virginia study suggests that older adults are not only more inclined than younger adults to make errors in recollecting details that have been suggested to them, but are also more likely than younger people to have a very high level of confidence in their recollections, even when wrong. The finding has implications regarding the reliability of older persons' eyewitness testimonies in courtrooms.

No Single Gene For Eye Color, Researchers Prove:

A study by researchers from The University of Queensland's Institute for Molecular Bioscience (IMB) and the Queensland Institute of Medical Research is the first to prove conclusively that there is no single gene for eye colour. Instead, it found that several genes determine the colour of an individual's eyes, although some have more influence than others.

Why Do Humans And Primates Get More Stress-related Diseases Than Other Animals?:

Why do humans and their primate cousins get more stress-related diseases than any other member of the animal kingdom? The answer, says Stanford University neuroscientist Robert Sapolsky, is that people, apes and monkeys are highly intelligent, social creatures with far too much spare time on their hands. "Primates are super smart and organized just enough to devote their free time to being miserable to each other and stressing each other out," he said. "But if you get chronically, psychosocially stressed, you're going to compromise your health. So, essentially, we've evolved to be smart enough to make ourselves sick."

Children Should Not Be Left Unsupervised With Dogs, Say Experts:

Children should not be left unsupervised to play with a dog, say experts in this week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites. Dog bites and maulings are a worldwide problem, particularly in children, write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls.

One In Three Boys Heavy Porn Users, Study Shows:

Boys aged 13 and 14 living in rural areas are the most likely of their age group to access pornography, and parents need to be more aware of how to monitor their children's viewing habits, according to a new University of Alberta study. A total of 429 students aged 13 and 14 from 17 urban and rural schools across Alberta, Canada, were surveyed anonymously about if, how and how often they accessed sexually explicit media content on digital or satellite television, video and DVD and the Internet. Ninety per cent of males and 70 per cent of females reported accessing sexually explicit media content at least once. More than one-third of the boys reported viewing pornographic DVDs or videos "too many times to count", compared to eight per cent of the girls surveyed.
