A lover of sleep? Clean your Genes (livescience.com)

Do you compagne is Samantha Sleeps in you, Paul, Prude cut off you some g. slack. prédilections people for promiscuity lie partially DNA, according to a new study.

A particular version of a young récepteur dopamine called DRD4 linked to tendency toward infidelity of the people and the name of one-day night, researchers to 30 November on open-access journal PloS one.

Even June already linked bank alcoholism and addiction, as well as less destructive sensations like a love film support. A studies linked to June a fairness for new social situation, Bell corrélation with political liberalism.

New study, researchers gather in detail the history of the sexual behavior and relations of 181 young adults. Also collect DNA échantillons in the jaw volunteers with analysé échantillons for presence will get some version of DRD4 sensations.

'' What we found was that man and variant of June DRD4 was more likely to have a history of the name of sex, including one-night and the history of infidelity, '' study find Justin Garcia, a man postdoctoraux in Binghamton University, State University in New York, said in a statement.

"The Stimulus to come together in a system of pleasure and reward, that is where the release of dopamine, '' Garcia said. "Of those cases in the name of sex, risk is high, and substantial stimulus variable all elements which ensure a dopamine was quickly."

The people looking for sensations June variant and about twice as likely to report a history of a-night is like those who have the variant June. Half of those with a love for risk was imprimée in DNA reported infidelity committed in the past, compared with 22 percent of the variant.

"The study do not give transgressors round," Garcia said. These associative Relations ", which means that not all and génotype this there will be one day night you commit infidelity. Indeed, many people without génotype this no longer has a night and commit infidelity. The study simply suggest that something higher unemployment rates and the quality of genetics that have been given the opportunity to engage in behavior. "

Protein folding via charge zippers

Jan. 18, 2013 — Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane. In the journal Cell, researchers of Karlsruhe Institute of Technology and the University of Cagliari are now reporting a novel charge zipper principle used by proteins to form functional units. "It is fascinating to see the elegant basic principles that are used by nature to construct molecular assemblies," explains Anne Ulrich, Director of the KIT Institute for Biological Interfaces. "A charge zipper between the charged side chains is an entirely unexpected mechanism used by membrane proteins to neutralize their charges such that they can be immersed into hydrophobic cell membranes....
