Wolfram Blog : Is Mathematica for K-12 Education? You Bet! - 0 views

  • let students explore concepts by manipulating an expression—or a graphical representation of an expression—with things like sliders, buttons, and checkboxes. When you wrap the Manipulate command around an existing calculation, Mathematica automatically creates a sophisticated interface that lets you and your students change values and see what happens in real time. It’s truly empowering! Now students can interact with everything from two-dimensional trajectory paths… to Riemann sums… to the phases of the planets… to almost anything else you can imagine. See the Wolfram Demonstrations Project for thousands of free ready-to-use examples.

Leonard Guarente Longevity Proteins Also May Be Linked To Mood Control - 0 views

  •  
    "Over the last 10 years, MIT biologist Leonard Guarente and other researchers have demonstrated that very-low-calorie diets provoke a comprehensive physiological response, which promotes survival due to a set of proteins called sirtuins. A new report by Guarente published online in Cell has now demonstrated that sirtuins may also have a key part in the psychological response to dietary restriction. "

MPG Nod2 is essential for temporal development of intestinal microbial communities. - 0 views

  •  
    "We found that adult Nod2-deficient mice display a substantially altered microbial community structure and a significantly elevated bacterial load in their faeces and terminal ileum compared to their wild-type counterparts. Interestingly, we demonstrate that these findings are also present in weaning mice, indicating a profound influence of Nod2 on the early development and composition of the intestinal microbiota. We demonstrate that NOD2 genotypes also influence the microbial composition in humans. Conclusions Our results point to an essential role of Nod2 for the temporal development and composition of the host microbiota, both in mice and in humans, which may contribute to the complex role of NOD2 for the aetiopathogenesis of Crohn's disease.

Marta Soares Tactile stimulation lowers stress in fish : Nature Communications : Nature... - 0 views

  •  
    "In humans, physical stimulation, such as massage therapy, reduces stress and has demonstrable health benefits. Grooming in primates may have similar effects but it remains unclear whether the positive effects are due to physical contact or to its social value. Here we show that physical stimulation reduces stress in a coral reef fish, the surgeonfish Ctenochaetus striatus. These fish regularly visit cleaner wrasses Labroides dimidiatus to have ectoparasites removed. The cleanerfish influences client decisions by physically touching the surgeonfish with its pectoral and pelvic fins, a behaviour known as tactile stimulation. We simulated this behaviour by exposing surgeonfish to mechanically moving cleanerfish models. Surgeonfish had significantly lower levels of cortisol when stimulated by moving models compared with controls with access to stationary models. Our results show that physical contact alone, without a social aspect, is enough to produce fitness-enhancing benefits, a situation so far only demonstrated in humans"

1 gene lost = 1 limb regained? Scientists demonstrate mammalian regeneration through si... - 1 views

  •  
    "A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution and reserved for creatures like flatworms, sponges, and some species of salamander. In a report published today in the Proceedings of the National Academy of Sciences, researchers from The Wistar Institute demonstrate that mice that lack the p21 gene gain the ability to regenerate lost or damaged tissue."

  •  
    "Plastic is produced in large amounts and used for various purposes. After use, huge amounts end up in the enviroment, often in the oceans. There, fragmentation leads to small particles, called microplastics. By filtrating and benthos-feeding organisms it can be inadvertently taken up as food. We demonstrate that the unicellular ciliate Paramecium, the freshwater flea Daphnia and the blue mussel Mytilus took up microplastic particles. Even more, in Mytilus, the plastic particles were transported into the digestive gland and accumulated in the respective cells. Subsequently, pathological alterations in the gland were noted. Microplastics are of concern because animals might starve with a full belly after uptaking large amounts of microplastics. As well, particles with sharp edges can injure the mucous layer of the gastrointestinal tract. Furthermore, persistent organic pollutants adhere at plastic and thus, may cause adverse impacts on the animal. We show options for solutions and indicate selected organisations working on the development of solution"

Ruth A. Atchley: PLOS ONE: Creativity in the Wild: Improving Creative Reasoning through... - 0 views

  •  
    "Here we show that four days of immersion in nature, and the corresponding disconnection from multi-media and technology, increases performance on a creativity, problem-solving task by a full 50% in a group of naive hikers. Our results demonstrate that there is a cognitive advantage to be realized if we spend time immersed in a natural setting. We anticipate that this advantage comes from an increase in exposure to natural stimuli that are both emotionally positive and low-arousing and a corresponding decrease in exposure to attention demanding technology, which regularly requires that we attend to sudden events, switch amongst tasks, maintain task goals, and inhibit irrelevant actions or cognitions. A limitation of the current research is the inability to determine if the effects are due to an increased exposure to nature, a decreased exposure to technology, or to other factors associated with spending three days immersed in nature."

Christina Zielinski: With the Immune System's Weapons - 0 views

  •  
    "When the right microorganisms are at work, immune cells involved in the development of autoimmune illnesses like psoriasis, multiple sclerosis and arthritis, can develop anti-inflammatory properties. Scientists at Charité - Universitätsmedizin Berlin and the Institute for Research in Biomedicine, Bellinzona, Switzerland, have now made this discovery. Their work is published in the current issue of the scientific journal Nature*. The scientists were able to prove that particular fungi activate the immune cells involved in the development of certain illnesses, whereas other microorganisms, in particular bacteria that are found naturally on our skin, lend an anti-inflammatory function to them. "This not only demonstrates that the composition of our microflora has a decisive role in the development of chronic illnesses, but also that the key cells causing illness can develop an anti-inflammatory 'twin'," explained Dr. Christina Zielinski, first author of the study."

Why Interacting with a Woman Can Leave Men "Cognitively Impaired": Scientific American - 0 views

  •  
    "It seems like his brain isn't working quite properly and according to new findings, it may not be. Researchers have begun to explore the cognitive impairment that men experience before and after interacting with women. A 2009 study demonstrated that after a short interaction with an attractive woman, men experienced a decline in mental performance. A more recent study suggests that this cognitive impairment takes hold even w hen men simply anticipate interacting with a woman who they know very little about. Sanne Nauts ... Daisy Grewal is a researcher at the Stanford School of Medicine, where she investigates how stereotypes affect the careers of women and minority scientists."

J. Lee, Vincent Harley: The male fight-flight response: MAO-A, A result of SRY regulati... - 0 views

  •  
    "Males and females differ in their biobehavioural response to stress, where males exhibit a heightened sympathetic response to stress compared with females. Specifically, Taylor et al. 1 propose that the classic "fight-or-flight" response to stress is adaptive for males, whilst females engage in a so-called "tend-and-befriend" response to stress. We propose that the Y-chromosome gene, SRY (sex-determining region on the Y chromosome), provides a genetic basis for the heightened sympathetic reactivity to stress and thus predominance of "fight-flight" response in males. Our idea is based on studies that demonstrate (i) the presence of SRY in brain regions and peripheral tissues abundant in catecholamines, (ii) the regulation of catecholamine synthesis and breakdown by SRY, and (iii) the role of SRY in voluntary movement and blood pressure in males"

Jonah Lehrer: The Psychology of Nakedness | Wired Science | Wired.com - 0 views

  •  
    "We are a superficial species. And this brings me to a fascinating new paper by an all star team of psychologists, including Kurt Gray, Joshua Knobe, Mark Sheskin, Paul Bloom and Lisa Feldman Barrett.. we automatically assume that the capacity to think and the capacity to feel are in opposition. It's a zero sum game. What does all this have to do with nakedness? The psychologists demonstrated it's quite easy to shift our perceptions of other people from having a mind full of agency to having a mind interested in experience: all they have to do is take off their clothes."

  •  
    "However, anthropological datasets show enormous complexity in how and why men and women behave the ways that they do [vi]. Studies in human biology and anthropology regularly demonstrate a dynamic flexibility and complex biocultural context for all human behavior, and this is especially true for gender.... No matter how much some want it to be true, it is just not that simple; there are no clear cut and easy answers to why we do what we do, and why men and women sometimes have problems getting along. To ignore the enormous wealth of data on how men and women are similar AND different and to try to tackle this enormously complex reality via one-dimensional approaches is just poor science."
