You like having one-night stands? A quickie in the loos on your lunch break, or a sneaky behind-the-back sh*g whilst your partner is away? Well we bet your mum does too, and more importantly so does the scientist who have found a gene that is linked to promiscuity and uncommitted sex. According to research by Justin Garcia, of Binghamton University, State University of New York, the dopamine receptor gene DRD4 is connected to promiscuous behaviour, and people with the gene "were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity."The motivation to have no-strings attached frolics stem from a system of pleasure and reward and is related to the release of dopamine. "In cases of uncommitted sex, the risks are high, the rewards substantial and the motivation variable — all elements that ensure a dopamine 'rush,'" said Garcia.People with the thrill-seeking gene variant were about twice as likely to report a history of one-night stands as those without the gene variant. Half of those with a love of risk imprinted in their DNA reported committing infidelity in the past, compared with 22 per cent of those without the variant.But don't think that you can officially blame being a slut just because nature made you this way."The study doesn't let transgressors off the hook," said Garcia."These relationships are associative, which means that not everyone with this genotype will have one-night stands or commit infidelity. Indeed, many people without this genotype still have one-night stands and commit infidelity. The study merely suggests that a much higher proportion of those with this genetic type are likely to engage in these behaviours."

We’ve all experienced it: an instant connection with a complete stranger that makes you believe in soul mates, destiny, and love at first sight—a feeling so strong you consider leaving everything and running off to Mexico with a virtual stranger. Then there are the moments when you feel in the zone and totally connected with your environment. Click, a new book by the New York Times bestselling authors of Sway, analyzes the mechanics of these magical moments.
When things clicks we feel more alive, more engaged, and more in touch with everything in an almost supernatural way—a description that parallels the use of stimulants like...

Swedish researchers believe they have uncovered a possible explanation for the link between mental health and creativity... Last year, The New York Times called the Mexican artist Martín Ramírez “simply one of the greatest artists of the 20th century.” What is so remarkable about his achievement, beyond the mesmerizing repetition of lines and images in his drawings, is that all of the work was created inside a mental institution. http://www.makeahistory.com/index.php/section-blog/374-art-and-mentalSwedish researchers believe they have uncovered a possible explanation for the link... more

People have typically viewed the benefits that accrue with social status primarily from the perspective of external rewards. A new paper in the February 1st issue of Biological Psychiatry, published by Elsevier suggests that there are internal rewards as well.
Dr. Martinez and colleagues found that increased social status and increased social support correlated with the density of dopamine D2/D3 receptors in the striatum, a region of the brain that plays a central role in reward and motivation, where dopamine plays a critical role in both of these behavioral processes.
The researchers looked at social status and social support in normal healthy volunteers who were scanned using positron emission tomography (PET), a technology that allowed them to image dopamine type 2 receptors in the brain.
This data suggests that people who achieve greater social status are more likely to be able to experience life as rewarding and stimulating because they have more targets for dopamine to act upon within the striatum.
Dr. Martinez explains their findings: "We showed that low levels of dopamine receptors were associated with low social status and that high levels of dopamine receptors were associated with higher social status. The same type of association was seen with the volunteer's reports of social support they experience from their friends, family, or significant other."
