In Flies' Innards, Vital Clues to Biodiversity - NYTimes.com - 0 views

  •  
    "How many mammal species live in the forest? It sounds like a simple question, but the actual distributions of shy, small or rare mammals are often murky, confounding conservationists seeking to protect them. Yet a paper published online on Tuesday in the journal Molecular Ecology explores a new way to track biodiversity: by capturing flies that feed on carcasses. The flies' stomachs offer DNA diaries of their recent meals, giving scientists clues to which animals live and die in the forest. "The animals are there, but you just don't see them," said Fabian Leendertz, a wildlife epidemiologist at the Robert Koch Institute in Berlin and an author of the paper. "Those flies will find them and will tell us what is there"

Seasonal effects on suicide rates - Wikipedia, the free encyclopedia - 0 views

  •  
    "These findings clearly state that there is a relationship between summer suicide rates and biochemical (e.g., plasma L-TRP and melatonin levels, [3H]paroxetine binding to blood platelets), metabolic (serum total cholesterol, calcium and magnesium concentrations), and immune (number of peripheral blood lymphocytes and serum sIL-2R) variables.[18] Another study focused on the association between depression, suicide, and the amount of polyunsaturated fatty acids (PUFA). They state that "depression is accompanied by a depletion of n-3 poly-unsaturated fatty acids".[22] Their methodology involved taking periodic blood samples-every month for one year-of healthy volunteers, allowing them to analyze the "PUFA composition in serum phospholipids and [relating] those data to the annual variation in the mean weekly number of suicides". They used an analysis of variance (ANOVA) to document their results, finding that PUFA like arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid all occurred at significantly lower rates in winter than in summer months. The association between depression, suicide, and PUFA rates is indicative of there being a biological factor in seasonal effects on suicide rates"

How deep must life hide to be safe on Europa? - 2 views

  •  
    If there is organic life deep under the ice on Europa, why would we need to disturb it at all? Potential source of unknown viruses etc. Risks of releasing something are low I guess, but the assumption that whatever may be there needs Earth-like conditions to survive and multiply is dangerous.

@biogarage Sick Bees - Part 3: The Bee Immune System @ Scientific Beekeeping - 0 views

  •  
    "Note that the antimicrobial peptides are produced largely in the fat bodies-so there would be less of this sort of response in forager bees, which don't maintain their fat bodies. This makes sense, since foragers aren't expected to live for long. However, keep in mind that the bees in protein-hungry colonies are unable to develop their fat bodies fully-this one point where nutrition ties in to immunity. Surprisingly, Jay Evans found that these genes are not upregulated in bees from CCD colonies, even though the bees are full of pathogens! there are a few potential explanations for this finding that come to mind: The bee hemocytes are not recognizing the pathogens as foreign (suppression of recognition systems, perhaps by viruses?). The colonies could be protein-starved. Something is suppressing the transcription of the genes, or their translation to peptides. Note that viruses can do this very thing, which I feel may be a big clue!"

Does sexual equality change porn? - Pornography - Salon.com - 0 views

  •  
    In what may feel like a flashback to the porn wars of the '60s, a new study investigates the link between a country's relative gender equality and the degree of female "empowerment" in the X-rated entertainment it consumes. Researchers at the University of Hawaii focused on three countries in particular: Norway, the United States and Japan, which are respectively ranked 1st, 15th and (yikes) 54th on the United Nations' Gender Empowerment Measure (GEM). To simplify their analysis, their library of smut was limited to explicit photographs of women "from mainstream pornographic magazines and Internet websites, as well as from the portfolios of the most popular porn stars from each nation." Then they set out to evaluate each image on both a disempowerment and an empowerment scale, using respective measures like whether the woman is "bound and dominated" by "leashes, collars, gags, or handcuffs" or "whether she has a natural looking body." Their hypothesis was that societies with greater gender equity will consume pornography that has more representations of "empowered women" and less of "disempowered women." It turned out the former was true, but, contradictory as it may sound, the latter was not. "While Norwegian pornography offers a wider variety of body types -- conforming less to a societal ideal that is disempowering to the average woman -- there are still many images that do not promote a healthy respect for women," the researchers explain. In other words, Norwegian porn showed more signs of female empowerment, but X-rated images in all three countries equally depicted women in demeaning positions and scenarios. This, the researchers surmise, "suggests that empowerment and disempowerment within pornography are potentially different constructs." So, gender equality is accompanied by sexual interest in a broader range of beauty types but not a decrease in porn's infantilization of females, use of dominating fetish gear on women or any of the other characteristics th

Quantum magic trick shows reality is what you make it - physics-math - 22 June 2011 - New Scientist - 2 views

  •  
    In 1967, Simon Kochen and Ernst Specker proved mathematically that even for a single quantum object, where entanglement is not possible, the values that you obtain when you measure its properties depend on the context. So the value of property A, say, depends on whether you chose to measure it with property B, or with property C. In other words, there is no reality independent of the choice of measurement. It wasn't until 2008, however, that Alexander Klyachko of Bilkent University in Ankara, Turkey, and colleagues devised a feasible test for this prediction. They calculated that if you repeatedly measured five different pairs of properties of a quantum particle that was in a superposition of three states, the results would differ for the quantum system compared with a classical system with hidden variables. That's because quantum properties are not fixed, but vary depending on the choice of measurements, which skews the statistics. "This was a very clever idea," says Anton Zeilinger of the Institute for Quantum Optics, Quantum Nanophysics and Quantum Information in Vienna, Austria. "The question was how to realise this in an experiment." Now he, Radek Lapkiewicz and colleagues have realised the idea experimentally. They used photons, each in a superposition in which they simultaneously took three paths. Then they repeated a sequence of five pairs of measurements on various properties of the photons, such as their polarisations, tens of thousands of times. A beautiful experiment They found that the resulting statistics could only be explained if the combination of properties that was tested was affecting the value of the property being measured. "there is no sense in assuming that what we do not measure about a system has [an independent] reality," Zeilinger concludes.

TEDxRheinMain - Prof. Dr. Thomas Metzinger - The Ego Tunnel - YouTube - 1 views

  •  
    Brain, bodily awareness, and the emergence of a conscious self: these entities and their relations are explored by Germanphilosopher and cognitive scientist Metzinger. Extensively working with neuroscientists he has come to the conclusion that, in fact, there is no such thing as a "self" -- that a "self" is simply the content of a model created by our brain - part of a virtual reality we create for ourselves. But if the self is not "real," he asks, why and how did it evolve? How does the brain construct the self? In a series of fascinating virtual reality experiments, Metzinger and his colleagues have attempted to create so-called "out-of-body experiences" in the lab, in order to explore these questions. As a philosopher, he offers a discussion of many of the latest results in robotics, neuroscience, dream and meditation research, and argues that the brain is much more powerful than we have ever imagined. He shows us, for example, that we now have the first machines that have developed an inner image of their own body -- and actually use this model to create intelligent behavior. In addition, studies exploring the connections between phantom limbs and the brain have shown us that even people born without arms or legs sometimes experience a sensation that they do in fact have limbs that are not there. Experiments like the "rubber-hand illusion" demonstrate how we can experience a fake hand as part of our self and even feel a sensation of touch on the phantom hand form the basis and testing ground for the idea that what we have called the "self" in the past is just the content of a transparent self-model in our brains. Now, as new ways of manipulating the conscious mind-brain appear on the scene, it will soon become possible to alter our subjective reality in an unprecedented manner. The cultural consequences of this, Metzinger claims, may be immense: we will need a new approach to ethics, and we will be forced to think about ourselves in a fundamentally new way. At

What is the difference between vapor and gas? ~ Wiki Mini For Chem - 0 views

  •  
    Difference between vapor and gas The term gas refers to a substance that is in its gaseous form or a substance that has a single defined thermodynamic state at room temperature whereas a vapor refers to a substance that is a equilibrium between two phases at room temperature, namely gaseous and liquid phase. All matter on earth exists in any of the three states: solid, liquid or gaseous. 'Gas' refers to a substance in the gaseous state. Gases do not have either shape or volume. However, the term 'vapor' or 'vapour' refers to a substance in equilibrium between two phases, usually liquid and gaseous. Vapor is not a state of matter but is a specific type of gas. Gases are in a gaseous state at room temperature. The molecules in a gas can expand to occupy any available volume as there is very little inter molecular attraction. On the other hand, the molecules of a vapor gain energy and vaporize from a substance which is either a solid or liquid at room temperature. For example, steam is a water vapor that turns into water at room temperature. Oxygen, which is a gas, will still be a gas at room temperature. Gas is a state of matter. Vapor is not, it is constantly in transition. An easy way to distinguish between vapor and gas is that vapor is something that can be seen or smelled or something that settles down on the ground, while one cannot see a gas but can only smell it. However, there are some exceptions to this classification, for example, water vapor. Water vapor cannot be smelt and it does not settle down on the ground.

Top 10 Data Integration and Management Challenges in the Pharma Value Chain | ACL Digital - 0 views

  •  
    Medicines and healthcare are synonymous globally. As treatments become more innovative, to address unmet clinical needs, it is important that there is innovation in the pharma value chain as well. In order that patients receive the right medicine, at the right time and the right place, there is a need for a complex value chain. The full set of activities that occur prior to a patient receiving a medicine, constitute the pharmaceutical value chain. This value would differ within markets and also between markets. https://www.acldigital.com/blogs/top-10-data-integration-and-management-challenges-pharma-value-chain

John Graham: Why is there no Nobel Prize in Biology? - 0 views

  •  
    "Sorry but all the Laurets mentioned either received the Nobel Prize for Medicine and Physiology or the Noble Prize for Chemistry. The fact that many of the researchers were working in areas that were not specifically associated with Chemistry or with Physiology and Medicine simply highlights how the criteria have been stretched to accomodate the achievements in Biology for which there is no specific Nobel prize."

Mikroplastik - ein unsichtbarer Störenfried - Holm - 2013 - Biologie in unserer Zeit - Wiley Online Library - 0 views

  •  
    "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 Immersion in Natural Settings - 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."

Official SCIENCE*: HIGH HEELS make you SEXY (Ladies) * The Register - 0 views

  •  
    "There is a strong contemporary association between high heels and female sexuality. We investigated the hypothesis that one motivation for women wearing high heels is that it artificially increases the femininity of gait. Biomechanical analyses revealed that wearing high heels led to increased femininity of gait including reduced stride length and increased rotation and tilt of the hips. This groundbreaking study was published this month in the scientific journal Evolution and Human Behavior. It was written by Paul H. Morris, Jenny White, Edward R. Morrison and Kayleigh Fisher"

Infusion of pseudo-poo cures gut infections in two women - Phenomena: Not Exactly Rocket Science - 0 views

  •  
    "People swap bacteria all the time-through sneezes and coughs, through hugs and sex, or through touching the same surfaces. Then there are people who swap bacteria because a doctor deliberately transplants faeces from one into the other. This isn't a bizarre medical perversion. It's usually a life-saving gambit. Faecal transplants-which are exactly what they sound like-are used to treat people who suffer from intense diarrhoea following rounds of antibiotics. The goal is simple: recalibrate the beneficial bacteria in a person's gut to fight off the ones that are causing them harm."

Do-it-yourself biotech: Ellen Jorgensen at TEDGlobal 2012 - 0 views

    "t turns out that all over the world there were people trying to do similar things - opening biohacker spaces. Three years later, this is a thriving global community. Each lab has a flavor of where it was created - people work together or alone, in big cities or small villages, they build things and take them apart, and do much, much more. The spirit is open. But what about the dark side? What about biosafety, biosecurity? The minute Genspace opened their doors, journalists called. And the only question they wanted to ask was, "Would this lab create the next Frankenstein?" The press was overestimating their capabilities - and underestimating their ethic"
