Infidelity might be genes (HealthDay)

FRIDAY, December 3, HealthDay News)--Genetics may help explain why some people have more of an elongated rod-shaped instrument of infidelity and promiscuity, says a new survey.

Researchers analyze 181 young adults, who provided a complete history of sexual activity and intimate partnerships DNA. Stated that the Dopamine receptor D4 (DRD4) plays an important role to play in this gene in sexual activities.

Previous research has linked DRD4 gene that affects brain chemistry, sensation seeking activities, such as gambling and alcohol use.

"What we found was a variant of a gene DRD4-were more likely to have to be committed, the protection of individuals with regard to discrimination on the basis of sex, including a one-night stands and infidelity, acts on the history of" to examine, Justin Garcia, Director of the laboratory, product line, anthropology, and health in the Binghamton University, State University, New York, said the University-Press release (in Finnish).

"Motivation to stem pleasure and reward, which is where Dopamine release will be. Cases, the agreement in the case of non-discrimination on the basis of sex, the risks are high rewards and motivation to significantly--variable for all elements, which ensure the Dopamine "rush," "explains Garcia.

Findings published in the online journal PLoS one current problem should not be considered as an excuse to cheating or promiscuity, Garcia emphasized.

"These [gene problem] relations are associative, which means that all of the genotype with do not have one night stands or Confirm infidelity. In fact, many people without this genotype is still one night stands and infidelity, "said Garcia."Investigation merely suggests that a much larger proportion of those genetic such measures would be likely to engage in these activities. "

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....
