Named Data Networking (NDN) - A Future Internet Architecture - 0 views

  •  
    'The Named Data Networking (NDN) project aims to develop a new Internet architecture that can capitalize on strengths - and address weaknesses - of the Internet's current host-based, point-to-point communication architecture in order to naturally accommodate emerging patterns of communication. By naming data instead of their locations, NDN transforms data into a first-class entity. The current Internet secures the data container. NDN secures the contents, a design choice that decouples trust in data from trust in hosts, enabling several radically scalable communication mechanisms such as automatic caching to optimize bandwidth.'

    "We have sensitive body parts wired to the same area of the brain as rodents' fine-tuned whiskers. In people, "stimulating the fingers, lips or face in general could all have a similar effect," says UCI doctoral student Melissa Davis, co-author of the study, which appears in the June issue of PLoS ONE. "It's gender-neutral," adds co-author Ron Frostig, professor of neurobiology & behavior. He cautions that the research, funded by the National Institutes of Health, is a first step, albeit an important one.... "with the potential for maybe doing things before a victim even reaches the emergency room.""

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."

Tung, Barreiro, Johnson, Gilad Social stress affects immune system gene expression in m... - 0 views

  •  
    "Previous research on rhesus macaques discovered that social rank influenced components of the stress response, brain, and immune system. With gene chip technology for measuring the expression of over 6,000 different genes, Tung, Gilad and colleagues at Yerkes, Emory University, and Johns Hopkins looked for the first time in primates at the effects of social rank on genetic function. Comparing 49 different female monkeys of different rank revealed significant changes in the expression of 987 genes, including 112 genes associated with immune system function. The result fits with data in monkeys where low rank and chronic stress lead to compromised immune function, and, more loosely, with human studies linking low socioeconomic status and high social stress to elevated disease risk."

UrtheCast.com/ - 0 views

  •  
    UrtheCast (pronounced "EarthCast") is a company created around a unique vision: to provide the world's first ever, live HD video feed of Earth from space. Working in an exclusive relationship with world-famous Russian Aerospace giant RSC Energia, UrtheCast is building, launching, installing, and operating two cameras on the Russian module of the International Space Station. Starting in mid-2012, video data of the Earth collected by our cameras will be down-linked to ground stations around the planet and then displayed in near real time on the UrtheCast web platform or distributed directly to our exclusive partners and customers.

The Neuroscience of Effort | Wired Science | Wired.com - 0 views

    "Rather, these successful men needed to also be blessed with "zeal and with capacity for hard labour." This study is a first glimpse into those essential qualities described by Galton, helping us map out the individual differences that make it slightly easier for some people to engage in hard labor. These diligent souls seem to get a bit more pleasure from the possibility of reward, but they also seem less sensitive to their inner complainer, that disruptive voice reminding them that minesweeper is more fun than editing, or that the ballgame on television is much more entertaining than their homework. At any given moment, there is a tug of war unfolding in our head, determining whether or not we're willing to put in the effort. This sentence only exists because, for a few minutes at least, I was able to win the war."

Scientists gear up to take a picture of a black hole - 2 views

    The event horizon telescope will only photograph the proximity to the event horizon, not the black hole itself which by definition remains invisible. If it succeeds it will be the first actual proof that black holes exist.

Georg Pohnert: Chemists reveal how algae delete unwanted 'competitors' - Shychemist - 0 views

  •  
    "Every morning when the sun comes up, the ocean ground is radically cleaned. As soon as the first rays of sunlight find their way into the water, the microalgae "Nitzschia cf pellucida" start their deadly 'morning hygiene'. The algae, the size of only some few micrometers, wrap themselves and their surroundings in a highly toxic poison: cyanogen bromide, a chemical relative of hydrocyanic acid, although much more toxic."

    University of Michigan researchers George Mashour, M.D., Ph.D., and Jimo Borjigin, Ph.D., provide the first scientific framework for near-death experiences. "The "near-death experience" reported by cardiac arrest survivors worldwide may be grounded in science, according to research at the University of Michigan Health System. Whether and how the dying brain is capable of generating conscious activity has been vigorously debated"

Gout : Gicht Stryer, Thomas sydenham Symptoms and Diagnosis - 0 views

  •  
    "An accurate and colorful discription of a gout attack was elegantly written in 1683 by Dr. Thomas Sydenham who was himself a sufferer of gout: The victim goes to bed and sleeps in good health. About 2 o'clock in the morning, he is awakened by a severe pain in the great toe; more rarely in the heel, ankle or instep. This pain is like that of a dislocation, and yet the parts feel as if cold water were poured over them. Then follows chills and shiver and a little fever. The pain which at first moderate becomes more intense. With its intensity the chills and shivers increase. After a time this comes to a full height, accommodating itself to the bones and ligaments of the tarsus and metatarsus. Now it is a violent stretching and tearing of the ligaments- now it is a gnawing pain and now a pressure and tightening. So exquisite and lively meanwhile is the feeling of the part affected, that it cannot bear the weight of bedclothes nor the jar of a person walking in the room. "

Model suggests how life's code emerged from primordial soup - 0 views

  •  
    By working with the simplest amino acids and elementary RNAs, physicists led by Rockefeller University's Albert J. Libchaber, head of the Laboratory of Experimental Condensed Matter Physics, have now generated the first theoretical model that shows how a coded genetic system can emerge from an ancestral broth of simple molecules.

Ten things we don't understand about humans - New Scientist - 0 views

  •  
    We belong to a remarkably quirky species. Despite our best efforts, some of our strangest foibles still defy explanation. But as science probes deeper into these eccentricities, it is becoming clear that behaviours and attributes that seem frivolous at first glance often go to the heart of what it means to be human.
