Don't advertise during sexy programmes - the viewer won't remember
People are less able to recall the brand of products advertised during programmes with a lot of sexual content, than if the advert is placed in similar programme that has no sexual content.
Beauty and the Brain
The phrase “easy on the eyes” may hit closer to the mark than we suspected. Experiments led by Piotr Winkielman, of the University of California, San Diego, and published in the current issue of
Psychological Science, suggest that judgments of attractiveness depend on mental processing ease, or being “easy on the mind.”
Trustworthy not lustworthy
Students who were shown pictures of people who looked like themselves found the images trustworthy, but they were not sexually attracted to the "lookalikes".
Psychologists showed students pairs of face photos, one that was subtly altered to resemble the student looking at the images and one that resembled another person.
The similiarities were not spotted by the undergraduates who were asked to decide between pairs of faces as to which was the most trustworthy. The majority of participants selected the "lookalike" face from each pair.
Monkey 'Pay-Per-View' Study Could Aid Understanding of Autism
Researches have found that monkeys will 'pay' juice rewards to see images of high-ranking monkeys or female hindquarters. They say their research technique offers a rigorous laboratory approach to studying the "social machinery" of the brain and how this machinery goes tragically awry in autism -- a disease that afflicts more than a million Americans and is the fastest growing developmental disorder.
Scientists uncover new field of research that could help police in crime scene forensics
A team of investigators led by scientists at the Translational Genomics Research Institute (TGen) have found a way to identify possible suspects at crime scenes using only a small amount of DNA, even if it is mixed with hundreds of other genetic fingerprints.
Bitter-tasting nectar and floral odors optimize outcrossing for plants
Animals "personally" bring their gametes together – seeking out sexual partners, mating, fertilizing, and reproducing. Plants, however, are sessile organisms and require the help of a third party, the pollinator, which can be a bird, mouse or insect that transport pollen to receptive stigmas frequently over large distances. The colors and shapes of flowers as well as their volatile signals and nectar attract and reward the pollinators for their efforts.
Genome sequence deepens mystery of inconspicuous sea creature
(PhysOrg.com) -- Resembling a smudge more than an animal, a mysterious life form known as a placozoan has now joined other obscure and primitive creatures whose genomes are providing insight into how animals first arose more than 650 million years ago.
Alcohol dependence among women is linked to delayed childbearing
Alcohol use during the teen years can not only lead to subsequent alcohol problems, it can also lead to risky sexual behavior and a greater risk of early childbearing. An examination of the relationship between a lifetime history of alcohol dependence (AD) and timing of first childbirth across reproductive development has found that AD in women is associated with delayed reproduction.
