YouTube - The Known Universe by AMNH - 0 views

  •  
    The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum,  is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.     Data: Digital Universe, American Museum of Natural History  http://www.haydenplanetarium.org/universe/    Visualization Software:  Uniview by SCISS    Director: Carter Emmart  Curator: Ben R. Oppenheimer  Producer: Michael Hoffman  Executive Producer: Ro Kinzler  Co-Executive Producer: Martin Brauen  Manager, Digital Universe Atlas: Brian Abbott    Music: Suke Cerulo    For more information visit http://www.amnh.org

Integrating Farming For Better Results With Trivedi Effects - 0 views

  •  
    The crop produced by the agriculture acts as the fodder for the livestock, and similarly the livestock produce manure or fertilizer which can in turn used for the crops growth. This method is more beneficial in comparison to the mono-culture approaches used otherwise.

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"

Game Theory and the Treatment of Cancer | MIT Technology Review - 0 views

  •  
    "Similarly, how should cancer biologists think about cancer cells capable of producing vascular endothelial growth factor, a protein that promotes the growth of blood vessels? Clearly, the importance of this protein only makes sense when thinking about a cancer cell's environment: how close it is to blood vessels that it can exploit, for example."

Social evolution: The ritual animal : Nature News & Comment - 0 views

  •  
    "The ritual mind Legare presented Brazilians with a variety of simpatias, and found that people judged them as more effective when they involved a large number of repetitive procedural steps that must be performed at a specific time and in the presence of religious icons. "We're built to learn from others," she says, which leads us to repeat actions that seemed to work for someone else - "even if we don't understand how they produce the desired outcomes"."

'Roy Taylor, Iain Frame Reversing' type 2 diabetes? | Quality in Care - 0 views

  •  
    "The results are indeed worthy of attention, with Prof Taylor's team finding that in an early stage clinical trial of 11 people who were put on a diet of just 600 calories As written about in Dr Ben Goldacre's latest Bad Science column, producing a pattern from experimental data to come to a conclusion can be a 'magical' experience, but medicine is an 'imperfect art'. "We all know one atom of experience isn't enough to spot a pattern." writes Goldacre, "But when you put lots of experiences together and process that data, you get new knowledge.""

Biological Link between Cancer and Depression - The Naked Scientists May 2009 - 0 views

  •  
    "Leah Pyter: Well basically what we know is that patients with cancer have a higher likelihood of also developing depression at some point in their disease progression, so whether that occurred before and is predisposing them to cancer, or it's due to the tumours themselves, or other aspects of having the disease, we don't know. We were only studying right now whether the cancer itself can cause depression. Chris Smith: How could a tumour trigger depression, because a tumour can occur anywhere in the body, therefore at the remote sites in the brain, so how could it trigger changes in brain activity? Leah Pyter: Sure, well what we hypothesized was that the tumours themselves can produce cytokines which has been shown before. Chris Smith: These are inflammatory chemicals that drive the immune system? Leah Pyter: Right, exactly! And there is also a pile of research on how cytokines can access the brain specifically regions of the brain that are associated with depression and anxiety and emotional behaviours, and they can access the brain both tumourally through the blood, or neurally through the vegas nerves.

Marta Soares Tactile stimulation lowers stress in fish : Nature Communications : Nature Publishing Group - 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"

The good, the bad, and the ugly: an fMRI invest... [Soc Neurosci. 2006] - PubMed - NCBI - 0 views

  •  
    "Social interactions require fast and efficient person perception, which is best achieved through the process of categorization. However, this process can produce pernicious outcomes, particularly in the case of stigma. This study used fMRI to investigate the neural correlates involved in forming both explicit ("Do you like or dislike this person?") and implicit ("Is this a male or female?") judgments of people possessing well-established stigmatized conditions (obesity, facial piercings, transsexuality, and unattractiveness), as well as normal controls. Participants also made post-scan disgust ratings on all the faces that they viewed during imaging. These ratings were subsequently examined (modeled linearly) in a parametric analysis. Regions of interest that emerged include areas previously demonstrated to respond to aversive and disgust-inducing material (amygdala and insula), as well as regions strongly associated with inhibition and control (anterior cingulate and lateral prefrontal cortex). Further, greater differences in activation were observed in the implicit condition for both the amygdala and prefrontal cortical regions in response to the most negatively perceived faces. Specifically, as subcortical responses (e.g., amygdala) increased, cortical responses (e.g., lateral PFC and anterior cingulate) also increased, indicating the possibility of inhibitory processing. These findings help elucidate the neural underpinnings of stigma"

Spiegelman: Scientists find molecular link to obesity/insulin resistance in mice - 0 views

  •  
    "For this study, the investigators bred mice lacking TRPV4 or administered a drug to deactivate it. In the absence of TRPV4, white cells turned on a set of genes that consume energy to produce heat, rather than storing the energy as excess fat. This "thermogenic" process normally occurs in brown or beige fat (commonly called "good fat"), which is found mostly in small animals and human infants to protect against cold. When the TRPV4-deficient mice were put on a high-calorie diet for several weeks, they did not become obese, and their level of fat cell inflammation and insulin resistance was lowered. "We have identified a target that, when inhibited, can activate beige adipose tissue and suppress inflammation," said Spiegelman."

Robin Mellors-Bourne: #Vitae #STEM Researchers' 'unrealistic' hopes of academic careers Times Higher Education - 0 views

  •  
    "There is a "significant credibility gap" between researchers' expectations and the likelihood of their forging long-term careers in higher education, a survey has found. More than three-quarters of research staff responding to the Careers in Research Online Survey 2013 said they aspired to a career in higher education and around two-thirds said they expected to achieve this. But it was "unrealistic to expect" that this number of research staff, or even half of those in the early stages of their career, would be able to secure a long-term research role in higher education, says the report, based on the survey produced by Vitae, the careers organisation for researchers."

New findings challenge assumptions about origins of life - 0 views

  •  
    Our genetic code is translated by two super-families of modern-day enzymes. Carter's research team created and superimposed digital three-dimensional versions of the two super-families to see how their structures aligned. Carter found that all the enzymes have virtually identical cores that can be extracted to produce "molecular fossils" he calls Urzymes-Ur meaning earliest or original. The other parts, he said, are variations that were introduced later, as evolution unfolded. These two Urzymes are as close as scientists have gotten to the actual ancient enzymes that would have populated the Earth billions of years ago.

@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!"

Bee calamity clarified :The Scientist [24th August 2009] - 0 views

  •  
    An illness that has been decimating US honeybees for more than three years probably isn't caused by a single virus, but by multiple viruses that wear down the bees' ability to produce proteins that can guard them against infection, according to a new study.

What scientists know about jewel beetle shimmer - 0 views

  •  
    "Jewel beetles" are widely known for their glossy external skeletons that appear to change colors as the angle of view changes. Now they may be known for something else--providing a blueprint for materials that reflect light rather than absorbing it to produce colors.
