People’s emotional reactions and desires in initial romantic encounters determine the fate of a potential relationship. Responsiveness may be one of those initial “sparks” necessary to fuel sexual desire and land a second date. However, it may not be a desirable trait for both men and women on a first date. Does responsiveness increase sexual desire in the other person? Do men perceive responsive women as more attractive, and does the same hold true for women’s perceptions of men? A study published in Personality and Social Psychology Bulletin seeks to answer those questions.Femininity and AttractivenessResearchers from the Interdisciplinary Center (IDC) Herzliya, the University of Rochester, and the University of Illinois at Urbana-Champaign, collaborated on three studies to observe people’s perceptions of responsiveness. People often say that they seek a partner that is “responsive to their needs,” and that such a partner would arouse their sexual interest. A responsive person is one that is supportive of another’s needs and goals. “Sexual desire thrives on rising intimacy and being responsive is one of the best ways to instill this elusive sensation over time,” lead researcher Gurit Birnbaum explains. “Our findings show that this does not necessarily hold true in an initial encounter, because a responsive potential partner may convey opposite meanings to different people.”In the first study, the researchers examined whether responsiveness is perceived as feminine or masculine, and whether men or women perceived a responsive person of the opposite sex as sexually desirable. …

Dreams, déjà vu and delusions caused by faulty "reality testing"
http://feeds.feedburner.com/~r/sciencedaily/top_news/top_health/~4/KCqUThN-GZo
New research from the University of Adelaide has delved into the reasons why some people are unable to break free of their delusions, despite overwhelming evidence explaining the delusion isn’t real.In a new paper published in the journal Frontiers in Psychology, University of Adelaide philosopher Professor Philip Gerrans says dreams and delusions have a common link — they are associated with faulty “reality testing” in the brain’s higher order cognitive systems.”Normally this ‘reality testing’ in the brain monitors a ‘story telling’ system which generates a narrative of people’s experience,” Professor Gerrans says.”A simple example of normal reality testing is the person who gets a headache, immediately thinks they might have a brain tumor, then dismisses that thought and moves on. Their story episode ‘I might have brain cancer’ gets tested and quickly rejected.”In someone who has problems with reality testing, that story might persist and may even be elaborated and translated into action. Such people can experience immense mental health difficulties, even to the point of becoming a threat to themselves or to others,” he says.In his paper, Professor Gerrans discusses delusions triggered by feelings of familiarity and unfamiliarity, such as the “Capgras delusion” — the delusion of “doubles.” One example is of a man who, after serious head injury following a motor vehicle accident, returned home from the hospital after a year only to state repeatedly that his family had been replaced by impostors.”His family looked familiar but didn’t feel familiar, and the story in his head made sense of that feeling. It didn’t matter how much people tried to point out that his family was the same, in his mind they had been completely replaced by impostors,” Professor Gerrans says.He says in the “Fregoli delusion,” people think they’re being followed by a familiar person in disguise as a way of coping with a feeling of familiarity evoked by seeing a stranger.”People also experience feelings of familiarity and unfamiliarity in dj vu — a sense that a new place is strangely familiar, and the reverse, jamais vu — a sense of extreme unfamiliarity evoked by a familiar place. However, such feelings do not lead to delusion in people whose reality testing is intact.”Professor Gerrans says better understanding this reality testing system could help to improve outcomes for people living with such difficulties.”Trying to treat someone experiencing these delusions by telling them the truth is not necessarily going to help, so new strategies need to be developed to assist them. Ultimately, that’s the aim of this work — to help explain the nature of reality testing in order to help people find a way of working through or around their delusions so that the delusions no longer adversely affect their lives.”Professor Gerrans’s new book, The Measure of Madness. Philosophy and Cognitive Neuropsychiatry (MIT Press), will be published this year.What’s the difference between a dream, a delusion and an hallucination? Professor Gerrans explains:Dream: The images, sensations and thoughts we experience during sleep. In dreams we simply have experiences, we don’t have beliefs about experience because “reality testing” systems are not active.Delusion: An irrational belief at odds with reality maintained in the face of obvious contrary evidence and logical argument.Hallucination: The apparent perception of an object not actually present.Dj vu: The feeling that you have previously experienced a situation which is in fact unfamiliar. Caused by an erroneous “sense of familiarity.”Jamais vu: The feeling that a familiar situation has not been experienced before. …

What Happens if You’re Injured by a Dangerous Product?
http://www.mybiologica.com/wp-content/uploads/2014/02/d1faDefectiveProducts-226x122.png
Whether it’s a laptop with an overheated battery, a car with airbags that fail to deploy, or prescription medication that leads to serious side effects, consumers are constantly using a variety of products that can and do lead to injuries, harm, and even death.When someone suffers an injury as the result of using a product, they often wonder if they can sue to recover damages. These types of cases are known as product liability cases. In order to prevail in such a case, consumers usually have to show that the product manufacturer is negligent.Liability and NegligenceNot every injury you suffer as the result of using a product means that you will be able to recover damages for your injuries. In order to win your case, you will have to be able to show that the product’s manufacturer was negligent in some way. When a product manufacturer releases a product into the marketplace, it must be sure that the product is safe. If the manufacturer makes a mistake and releases a product that poses a danger to the consumer, it can be held liable for any harm caused by the product.In product liability cases, the person suing the manufacturer, called the plaintiff, typically has to show one of three things:The manufacturer made a defective product. Many product injury cases arise because a manufacturer doesn’t build a product correctly. For example, a chair missing an important screw or a piece of exercise equipment that isn’t assembled correctly can easily lead to someone getting hurt. In such a situation, the manufacturer is often held liable for those injuries because they manufactured a product with a defect and then sent it into the marketplace. The manufacturer designed a dangerous product. …

Primitive artificial cell turned into complex biological materials
http://feeds.feedburner.com/~r/sciencedaily/top_news/top_science/~4/r_MMKxEKg94
Imagine starting from scratch with simple artificial microscopic building blocks and ending up with something much more complex: living systems, novel computers or every-day materials. For decades scientists have pursued the dream of creating artificial building blocks that can self-assemble in large numbers and reassemble to take on new tasks or to remedy defects. Now researchers have taken a step forward to make this dream into a reality.”The potential of such new human-made systems is almost limitless, and many expect these novel materials to become the foundation of future technologies,” says Dr. Maik Hadorn from Department of Chemistry and Applied Biosciences at ETH Zrich, who conducted the research as a postdoctoral research fellow at University of Southern Denmark (SDU).Over the last three years he and the colleagues Eva Boenzli, Kristian T. Srensen and Martin M. Hanczyc from the Center for Fundamental Living Technology (FLinT) at SDU have worked on the challenges of making primitive building blocks assemble and turn into something functional.”We used short DNA strands as smart glue to link preliminary stages of artificial cells (called artificial vesicles) to engineer novel tissue-like structures,” says Dr. Maik Hadorn.As part of the EU-sponsored project MATCHIT (MATrix for CHemical Information Technology) Dr. Maik Hadorn and coworkers have earlier showed that short DNA strands can guide the self-assembly process of artificial vesicles; that two types of artificial vesicles can be linked in a way predefined by the person conducting the experiment, and that assembled structures can be reassembled, when triggered externally.In their most recent scientific article, published in Langmuir in December 2013, the researchers from SDU, in collaboration with colleagues from Italy and Japan, not only increased the complexity of the self-assembled structures that are now composed of several types of artificial vesicles — they also loaded one vesicle type with a basic cellular machinery derived from bacterial cells. This enabled these vesicles to translate an encapsulated genetic blueprint into a functional protein.Put together the researchers have managed to engineer controlled assemblies that are visible to the naked eye and that resemble natural tissues in their architecture as well as in their functionalities.Methods of constructing simple artificial structures have been known for decades, but only the use of DNA strands that act as a smart glue has allowed the researchers to overcome shortcomings of precedent methods and to engineer higher-order structures of predefined and programmable architecture.”As the artificial vesicles resemble natural cells both in size and composition, they are an ideal starting point for a multitude of applications. One application can be a temporal support for wound healing: A wound may be covered with assemblies of vesicles that are tailored in a patient specific manner. …

Obese children more likely to have complex elbow fractures, further complications
http://feeds.feedburner.com/~r/sciencedaily/top_news/top_health/~4/pmHINLDon90
Pediatric obesity is currently an epidemic, with the prevalence having quadruped over the last 25 years. Children diagnosed with obesity can be at risk for various long-term health issues and may be putting their musculoskeletal system at risk. According to new research in the February issue of the Journal of Bone and Joint Surgery(JBJS), obese children who sustain a supracondylar humeral (above the elbow) fracture can be expected to have more complex fractures and experience more postoperative complications than children of a normal weight.”These findings show that children diagnosed with obesity are more likely to sustain these complex fractures from something as simple as falling onto an outstretched hand while standing, and these types of falls are quite common,” said author Michelle S. Caird, MD, assistant professor in the department of orthopaedic surgery at the University of Michigan. “Our research aims to remind parents that there are many serious risks to childhood obesity, including fractures and surgical complications. It’s important to ensure that children get the proper amount of exercise and to build their bone banks early in life to a strong and healthy frame.”Specific Study DetailsMore than 350 patients ranging in age from 2 to 11 years old who had undergone operative treatment for supracondylar humeral fractures were included in the study. Patient records were reviewed for demographic data, body mass index (BMI) percentile, and injury data. Forty-one children were underweight (BMI <5<sup>th percentile), 182 were normal weight (BMI in the 5th to 85th percentile), 63 were overweight (BMI in the >85th percentile), and 68 were obese (BMI in the >95th percentile). The study included 149 patients with type-2 fractures (a break through part of the bone at the growth plate and crack through the bone shaft), 11 of whom were diagnosed with obesity; and 205 patients with type-3 fractures, 57 of whom were diagnosed with obesity. Complex fractures were defined as Type-3 fractures (completely displaced), fractures with multiple fracture lines, open fractures where the bone is exposed through the skin, and multiple fractures in the same arm. …
