Another scientific proof of the difference in social perception between men and women

2013-07-31
(Press-News.org) "The Love Hormone", Oxytocin affects men and women differently in social contexts- in men it improves the ability to identify competitive relationships whereas in women it facilitates the ability to identify kinship. "These findings are in agreement with previous studies on the social differences between the sexes: women tend to be more communal and familial in their behavior, whereas men are more inclined to be competitive and striving to improve their social status", said Prof. Simone Shamay-Tsoory from the Dept. of Psychology at the University of Haifa who led the research. The hormone Oxytocin is released in our bodies in various social situations, and it is better known as "The Love Hormone" since our bodies release it at high concentrations during positive social interactions such as falling in love, experiencing an orgasm or giving birth and breastfeeding. In her previous researches, Prof. Shamay-Tsoory discovered that the hormone is also released in our body during negative social interactions such as jealousy or gloating. In the current study, conducted with the help of research students Meytal Fischer-Shofty and Yechiel Levkovitz, researchers tried to find out what effect Oxytocin would have on women's and men's accurate perception of social interactions. 62 men and women aged 20-37 years participated in the current research. Half of the participants received an intranasal dose of Oxytocin while the other half received a placebo. After a week, the groups switched with participants undergoing the same procedure with the other substance (i.e. Placebo or Oxytocin). Following treatment, video clips showing various social interactions were screened. Participants were asked to analyze the relationships presented in the clips by answering questions that focused mainly on indentifying relationships of kinship, intimacy and competition. Participants were expected to base their answers, among other things, on gestures, body language and facial expressions expressed by the individuals in the clips. The results showed that Oxytocin improved the ability of all the participants to better interpret social interactions in general. When the researchers examined the differences between the sexes they discovered that following treatment with Oxytocin, men's ability to correctly interpret competitive relationships improved, whereas in women it was the ability to correctly identify kinship that improved. Surprisingly, researchers discovered that "The Love Hormone" doesn't help women or men to better identify intimate situations. According to them, since the ability to correctly identify intimate situations was substantially low among all participants in the study, there is evidence to say that correctly identifying an intimate relationship between two people is intricate and complicated. "Our results coincide with the theory that claims the social-behavioral differences between men and women are caused by a combination of cultural as well as biological factors that are mainly hormonal", concluded Prof. Shamay-Tsoory.

The naked mole-rat's secret to staying cancer free

2013-07-31
Mice and rats have long since been a standard animal model for cancer research, mainly due to their short lifespan of four years on average and high incidence of cancer. Naked mole rats however, are a mystery among mammals. This social tiny African subterranean rodent has a maximum lifespan exceeding 30 years and most surprisingly, is cancer-resistant. The fact that so far, not a single incident of cancer has been detected makes the naked mole rat a fitting model for finding novel ways to fight cancer. Recently, a team of researchers from the University of Rochester ...

Scientists at Mainz University decode mechanisms of cell orientation in the brain

2013-07-31
When the central nervous system is injured, oligodendrocyte precursor cells (OPC) migrate to the lesion and synthesize new myelin sheaths on demyelinated axons. Scientists at the Institute of Molecular Cell Biology at Johannes Gutenberg University Mainz (JGU) have now discovered that a distinct protein regulates the direction and movement of OPC toward the wound. The transmembrane protein NG2, which is expressed at the surface of OPCs and down-regulated as they mature to myelinating oligodendrocytes, plays an important role in the reaction of OPC to wounding. The results ...

Insect-inspired super rubber moves toward practical uses in medicine

2013-07-31
The remarkable, rubber-like protein that enables dragonflies, grasshoppers and other insects to flap their wings, jump and chirp has major potential uses in medicine, scientists conclude in an article in the journal ACS Macro Letters. It evaluates the latest advances toward using a protein called resilin in nanosprings, biorubbers, biosensors and other applications. Kristi Kiick and colleagues explain that scientists discovered resilin a half-century ago in the wing hinges of locusts and elastic tendons of dragonflies. The extraordinary natural protein tops the best synthetic ...

Sensitive parenting can boost premature children's school performance

2013-07-31
Sensitive parenting helps protect against the negative effects of being born prematurely on children's school success, a new study has found. Children born prematurely are at risk of a variety of neurological impairments which can mean they are more likely to need special educational support when they reach school age. But a new study led by the University of Warwick shows that parents of very preterm and very low birthweight (VP/VLBW) children can increase their child's academic achievement through sensitive and cognitively stimulating parenting. Researchers looked ...

Progress in using ethanol to make key raw material now produced from oil

2013-07-31
Ethanol from corn and other plants could become the sustainable, raw material for a huge variety of products, from plastic packaging to detergents to synthetic rubber, that are currently petroleum-based. This was the conclusion of an article published in the ACS journal Industrial & Engineering Chemistry Research. Yingzhe Yu and colleagues point out that a chemical called ethylene, now produced from petroleum, is one of the most important raw materials for everyday products. Ethylene is used to make hundreds of products, including polyethylene, the world's most widely ...

Studying the emotions which cause opinions to change

2013-07-31
Social phenomena fascinate with their complexity, but are not easily understood. Pawel Sobkowicz, an independent researcher based in Warsaw, Poland, has developed a model to study the dynamics of normal people, called 'agents', and their response to a given piece of information, depending on their emotional state. In a study about to be published in EPJ B, the author shows that opinion dynamics differ depending on whether the agent is agitated or not. Key social questions of interest have been the object of previous studies using physics tools. The field of magnetic interactions ...

New protein discovered with vast potential for treatment of cancer and other diseases

2013-07-31
In cancer research, discovering a new protein that plays a role in cancer is like finding a key and a treasure map: follow the clues and eventually there could be a big reward. At least that's the hope from a new study published in the journal Nature that discovered a novel protein called ceramide-1 phosphate transport protein (CPTP) -- a finding that could eventually lead to the development of new drugs to treat a variety of cancers and other conditions involving inflammation and thrombosis, or blood clotting. The identification of CPTP was the result of an international ...

UT Austin researchers successfully spoof an $80 million yacht at sea

2013-07-31
AUSTIN, Texas — This summer, a radio navigation research team from The University of Texas at Austin set out to discover whether they could subtly coerce a 213-foot yacht off its course, using a custom-made GPS device. Led by assistant professor Todd Humphreys of the Department of Aerospace Engineering and Engineering Mechanics at the Cockrell School of Engineering, the team was able to successfully spoof an $80 million private yacht using the world's first openly acknowledged GPS spoofing device. Spoofing is a technique that creates false civil GPS signals to gain control ...

Georgia Tech uncovers iOS security weaknesses

2013-07-31
Researchers from the Georgia Tech Information Security Center (GTISC) have discovered two security weaknesses that permit installation of malware onto Apple mobile devices using seemingly innocuous applications and peripherals, uncovering significant security threats to the iOS platform. "Apple utilizes a mandatory app review process to ensure that only approved apps can run on iOS devices, which allows users to feel safe when using any iOS app," said GTISC Associate Director Paul Royal, also a research scientist in the College of Computing. "However, we have discovered ...

Sediment trapped behind dams makes them 'hot spots' for greenhouse gas emissions

2013-07-31
With the "green" reputation of large hydroelectric dams already in question, scientists are reporting that millions of smaller dams on rivers around the world make an important contribution to the greenhouse gases linked to global climate change. Their study, showing that more methane than previously believed bubbles out of the water behind small dams, appears in ACS' journal Environmental Science & Technology. Andreas Maeck and colleagues point out that the large reservoirs of water behind the world's 50,000 large dams are a known source of methane. Like carbon dioxide, ...
