5 studies you may have missedHere's a roundup of five medical studies published this week that might give you new insights into your health, mind and body. Remember, correlation is not causation - so if a study finds a connection between two things, it doesn't mean that one causes the other. Verbal development linked to drinking Researchers found that, in twin pairs, the twin who began speaking earlier in life had a higher likelihood of more frequent drinking than his or her same-aged sibling at some point in adolescence. The twin who learned to read first had a higher probability of drinking or intoxication in young adulthood. This does not suggest that verbal skills cause drinking behaviors. Peer associations are related to both, says lead study author Antti Latvala. It's likely a different phenomenon than the association between poorer cognitive skills and the risk for severe problems related to drinking. "Even though better verbal skills may predict more drinking in adolescence, this finding needs to be seen in the context of such drinking being very common and almost normative among adolescents," Latvala said in an e-mail. Living mice get stem cells Stem cell science generally takes place outside living beings, so it was exciting this week when scientists announced they had created stem cells in mice. Specifically, they reprogrammed adult mouse cells so they would act as embryonic stem cells would. The next step will be regenerating specific types of cells. “We have demonstrated reprogramming,” Manuel Serrano, a cancer researcher at the Spanish National Cancer Research Centre in Madrid, told Nature.com. “Now we have to show regeneration.” Scientists find left-handed genes Not to say that genes have hands, but there is a gene called PCSK6 that is associated with relative hand skill. Researchers saw strong correlations between this variant of this gene and left- vs. right-handedness, based on data from 3,300 participants. Researchers found that many genetic variants contribute to handedness, and some of them are in genes involved in body asymmetry. When PCSK6 is disrupted in mice, for instance, their organs may develop on the wrong side of the body. New Scientist reports: "This may help explain why left-handedness still persists in a right-dominated world: so many genes contribute to the trait that it is impossible to silence them all." Estrogen contributes to men's aging woes It has been long thought that diminishing testosterone among aging men is responsible for such phenomena as low sex drive and belly weight gain. But a new study in the New England Journal of Medicine suggests that estrogen, a female sex hormone, also plays an important role. Scientists say lowered levels of estrogen as men age are also to blame for common complaints of aging, such as diminished libido. Estrogen is involved with fat accumulation, while testosterone levels are associated with muscle size and strength, study authors say. Both hormones regulate sexual function. "In light of what the Women's Health Initiative discovered about the unexpected effects of estrogen replacement therapy in women, we need a Men's Health Initiative to investigate those questions before large-scale testosterone replacement can be recommended," study author Dr. Joel Finkelstein of Massachusetts General Hospital said in a news release. Smaller testicles, more-involved dads? Get ready for a laugh: Scientists conducted a study suggesting that fathers with smaller testicles have a greater likelihood of being nurturing to their children. "Fathers' testicular volume and testosterone levels were inversely related to parental investment," the study says, "and testes volume was inversely correlated with nurturing-related brain activity when viewing pictures of their own child." This does not mean that fathers with large testicles are bad parents, of course. CNN's Josh Levs has the full scoop on this ballsy study.

CASOS DE TORTURAS ELECTRONIC HARASSMENT Y VOICE TO SKULL VENEZUELA.
ESTIMADOS POLÍTICOS SECRETARIA DE ESTADO.
SR OBAMA, MUCHAS DE LAS VICTIMAS DE TORTURAS MENTALES EN VENEZUELA LAS CUALES ESCUCHAN VOCES EN EL CEREBRO SOBRE TODO CON CONEXIONES A MEDIOS DE COMUNICACIÓN COMO CNN EN VENEZOLANOS DICEN CONSTANTEMENTE QUE LAS AGENCIAS LAS AGENCIAS Y ORGANIZACIONES DE ESTUDIOS DE LA RAZA HUMANA A LAS QUE USTEDES ESTÁN PAGANDO MILLONES DE DOLARES POR MINUTOS DE TRANSMISIÓN, IRRADIACIÓN Y MANIPULACIÓN EN HABITANTES DE VENEZUELA. NOS DICEN QUE LAS AGENCIAS QUE TRABAJAN PARA USTEDES; NORTE AMERICANAS, EUROPEAS Y ASIÁTICAS COMO PARE DE LAS TORTURAS, LES GRITAN TODA CLASE DE GROCERIAS PARA IDENTIFICAR ACTIVIDAD DE GRUPOS CELULARES REFERIDOS A ALMACENAMIENTO DE MEMORIA PARA SER DESTRUIDOS O CAUTERIZADOS COMO PARTE DE TÉCNICAS PARA PRODUCIR DETERIORO GENÉTICO O PATOLOGÍAS GENÉTICAS, DURANTE AÑOS DE VENTA DE INFORMACIÓN EN PATRONES NEURALES A OTRAS AGENCIAS EN NEGOCIOS.
MUY SERIAMENTE LES PEDIMOS A USTEDES PRESIDENTES NO CONTINÚEN PAGANDO DINERO AUMENTANDO LOS GASTOS DE BANCOS DE LOS ESTADOS ENTRE ELLOS DEL NORTE AMERICANOS PARA ESTE TIPO DE ESTUDIOS GENOCIDAS.
LES PEDIMOS YA QUE ES PUBLICO QUE ESTÁN UTILIZANDO ESTE TIPO DE TECNOLOGÍAS PARA REALIZAR CRÍMENES EN DIFERENTES LUGARES DEL MUNDO.
LES PEDIMOS YA QUE ES PUBLICO QUE ESTÁN UTILIZANDO ESTE TIPO DE TECNOLOGÍAS PARA REALIZAR CRÍMENES EN DIFERENTES LUGARES DEL MUNDO INCLUSO PERMITIENDO QUE SE CONECTEN DESDE PAÍSES ASIÁTICOS CON LOS QUE TIENEN CONFLICTOS SOLO CON LA INTECION DE ROBAR Y TRAFICAR DIFERENTES PRODUCTOS.
TAMBIÉN LES PEDIMOS NO CONTINÚEN ESPERANDO TIEMPO TRATANDO QUE LAS VICTIMA MUERAN POR ESTA RAZÓN;
SABEMOS QUE LA MEJOR PARTE DE ESTOS ESTUDIOS PARA ORGANIZACIONES DE ESTUDIOS DE LA RAZA HUMANA POLÍTICOS Y ORGANIZACIONES DESDE EL PUNTO DE VISTA DE INGRESOS EN ESTUDIOS DE LA RAZA HUMANA ES EN HUMANOS MUERTOS YA QUE DISUELVEN SUS TEJIDOS.
