Just How Dangerous Is Sitting All Day? [INFOGRAPHIC] - 0 views

  •  
    Sitting down, which most of us do for at least eight hours each day, might be the worst thing we do for our health all day. We've been preaching the benefits of stand-up desks for a while around here - and no one needs this good news more than social media-obsessed web geeks. A recent medical journal study showed that people who sit for most of their day are 54% more likely to die of a heart attack.

    One way to change something big is to get people really riled up about how you've changed something small. Repaint the boat, and let them to argue about that. By the time they've realized that green is no worse than blue, they won't have the energy to wonder whether it was a smart idea for you to set sail for Australia.

The Heroic Theory of Scientific Development « Apperceptual - 0 views

  •  
    Multiple Discovery is a very thorough study of independent simultaneous discovery in the history of science and technology. It seems that there is almost no instance of a great discovery or invention that was not discovered independently and simultaneously. In addition to a careful historical study, Lamb and Easton present a theory to explain multiple discovery, which they call evolutionary realism.

First successful transplantation of a synthetic windpipe | KurzweilAI - 0 views

  •  
    A 36-year-old man has received the world's first synthetic trachea, made from a synthetic scaffold seeded with his own stem cells, in an operation at the Karolinska University Hospital in Stockholm, Sweden. Professor Paolo Macchiarini of Karolinska University Hospital and Karolinska Institutet led an international team, including professor Alexander Seifalian from University College London, who designed and built the nanocomposite tracheal scaffold, and Harvard Bioscience, which produced a specifically designed bioreactor used to seed the scaffold with the patient´s own stem cells. The cells were grown on the scaffold inside the bioreactor for two days before transplantation to the patient. Because the cells used to regenerate the trachea were the patient's own, there has been no rejection of the transplant and the patient is not taking immunosuppressive drugs. "The big conceptual breakthrough is that we can move from transplanting organs to manufacturing them for patients," says David Green, the president of Harvard Bioscience in Holliston, Massachusetts. Transplantations of tissue-engineered windpipes with synthetic scaffolds in combination with the patient's own stem cells as a standard procedure means that patients will not have to wait for a suitable donor organ. Patients could benefit from earlier surgery and have a greater chance of cure. This would be of especially great value for children, since the availability of donor tracheas is much lower than for adult patients.

    Unification theory with no extra dimensions. The first part unifies the strong nuclear force with the gravitational force in a mathematical way; the quantum vacuum is treated as a deformable system by the strong nuclear force. The second part unifies the nuclear force with the quantum vacuum in a hypothetical structure; the quantum vacuum is treated as a supersymmetric and metastable system with properties related to the different types of particles' motion.

How to Fix and Remove Nettraveler Infection - 0 views

  •  
    Nettraveler is a cyber-threat to the computers. It is an infection with high risk and capability to collapse the entire system, within no time. The intruder interferes into the system, steals significant and sensitive information, and reports this information to its users. It usually skins with frequently used applications or Windows processes to hide from security shields.

How do you feel about the term 'citizen science'? | OceanSpaces - 0 views

  • The reason such a plethora of terms has proliferated is that each comes with the baggage - like how 'citizen science' might sound to an undocumented worker - of preconceived notions and affiliation with a particular structure of program. No one term has yet emerged to describe the wide spectrum of participatory science. Here at OST, we’ve decided to use the term ‘citizen science’ for a variety of reasons, most notably that it’s one of the easiest to understand and becoming one of the most popular. But we still have feelings about the term, so we’ve done a straw poll of staff members to see how they feel.

SkyandTelescope.com - Homepage News - "Pioneer Anomaly" Solved? - 0 views

  • Turyshev has spent the last several years retrieving archival tracking records from obsolete storage media (those classic magnetic tapes, some of them corrupted) as well as detailed specifications of the Pioneer spacecraft itself from 40 years ago. He likens his searching and discovery to rooting around a dusty attic. "No one told me what I'd be getting into," he says. The Pioneer missions lasted so long that they outlived programming languages and data formats. (The Pioneers were launched in the days of punched cards.)

The Technium: The Unabomber Was Right - 0 views

  • Besides lacking a desirable alternative, the final problem with destroying civilization as we know it is that the alternative, such as it has been imagined by the self-described “haters of civilization”, would not support but a fraction of the people alive today. In other words, the collapse of civilization would kill billions. Ironically the poorest rural inhabitants would fare the best, as they could retreat to hunting gathering with the least hurdle, but billions of urbanites would die once food ran out and disease took over. The anarcho-primitives are rather sanguine about this catastrophe, arguing that accelerating the collapse early might save lives in total.
  • The ultimate problem is that the paradise the Kaczynski is offering, the solution to civilization so to speak, is the tiny, smoky, dingy, smelly wooden prison cell that absolutely nobody else wants to dwell in. It is a paradise billions are fleeing from. Civilization has its problems but in almost every way it is better than the Unabomber’s shack. The Unabomber is right that technology is a holistic, self-perpetuating machine. He is wrong to bomb it for many reasons, not the least is that the machine of civilization offers us more actual freedoms than the alternative. There is a cost to run this machine, a cost we are only beginning to reckon with, but so far the gains from this ever enlarging technium outweigh the alternative of no machine at all.

PLoS ONE: A Demonstration of the Transition from Ready-to-Hand to Unready-to-Hand - 1 views

  • In Chapter III of Being and Time, Heidegger distinguishes three modes of experiencing the world. Most human activity, Heidegger argued, is absorbed, skillful engagement with entities in the world. When we are coping skillfully with the world, we experience entities around us as ready-to-hand.
  • Heidegger argues that skilled coping, when we engage with entities as ready-to-hand, is our primary way of engaging with the world. Sometimes, though, our skillful coping is temporarily disturbed. When this happens, we encounter entities as unready-to-hand. When we go from smoothly hammering to having difficulty, our experience of the previously ready-to-hand entities changes: we experience the hammer, nails and board as failing to serve their function appropriately.
  • Heidegger's third way of experiencing the world is as present-at-hand. The hammer is encountered as present-at-hand when we stop hammering and consider the hammer's shape or color or weight; when considered this way the hammer is no longer a useful tool but merely an object with various properties. Heidegger argued that readiness-to-hand is primary in two ways. First, the majority of our experience of the world is engaging with entities ready-to-hand. Second, readiness-to-hand is, from a phenomenological standpoint, ontologically primary while the other modes are derivative of it.

Human Computer Interaction (HCI) by John M. Carroll - Interaction-Design.org: HCI, Usab... - 0 views

  • The challenge of personal computing became manifest at an opportune time. The broad project of cognitive science, which incorporated cognitive psychology, artificial intelligence, linguistics, cognitive anthropology, and the philosophy of mind, had formed at the end of the 1970s. Part of the programme of cognitive science was to articulate systematic and scientifically-informed applications to be known as "cognitive engineering". Thus, at just the point when personal computing presented the practical need for HCI, cognitive science presented people, concepts, skills, and a vision for addressing such needs. HCI was one of the first examples of cognitive engineering. Other historically fortuitous developments contributed to establishment of HCI. Software engineering, mired in unmanageable software complexity in the 1970s, was starting to focus on nonfunctional requirements, including usability and maintainability, and on non-linear software development processes that relied heavily on testing. Computer graphics and information retrieval had emerged in the 1970s, and rapidly came to recognize that interactive systems were the key to progressing beyond early achievements. All these threads of development in computer science pointed to the same conclusion: The way forward for computing entailed understanding and better empowering users.
  • One of the most significant achievements of HCI is its evolving model of the integration of science and practice. Initially this model was articulated as a reciprocal relation between cognitive science and cognitive engineering. Later, it ambitiously incorporated a diverse science foundation, notably Activity Theory, distributed cognition, and ethnomethodology, and a culturally embedded conception of human activity, including the activities of design and technology development. Currently, the model is incorporating design practices and research across a broad spectrum. In these developments, HCI provides a blueprint for a mutual relation between science and practice that is unprecedented.
  • In the latter 1980s and early 1990s, HCI assimilated ideas from Activity Theory, distributed cognition, and ethnomethodology. This comprised a fundamental epistemological realignment. For example, the representational theory of mind, a cornerstone of cognitive science, is no longer axiomatic for HCI science. Information processing psychology and laboratory user studies, once the kernel of HCI research, became important, but niche areas. The most canonical theory-base in HCI now is socio-cultural, Activity Theory. Field studies became typical, and eventually dominant as an empirical paradigm. Collaborative interactions, that is, groups of people working together through and around computer systems (in contrast to the early 1980s user-at-PC situation) have become the default unit of analysis. It is remarkable that such fundamental realignments were so easily assimilated by the HCI community.

The Technium: The World Without Technology - 0 views

  • Although strictly speaking simple tools are a type of technology made by one person, we tend to think of technology as something much more complicated. But in fact technology is anything designed by a mind. Technology includes not only nuclear reactors and genetically modified crops, but also bows and arrows, hide tanning techniques, fire starters, and domesticated crops. Technology also includes intangible inventions such as calendars, mathematics, software, law, and writing, as these too derive from our heads. But technology also must include birds' nests and beaver dams since these too are the work of brains. All technology, both the chimp's termite fishing spear and the human's fishing spear, the beaver's dam and the human's dam, the warbler's hanging basket and the human's hanging basket, the leafcutter ant's garden and the human's garden, are all fundamentally natural. We tend to isolate human-made technology from nature, even to the point of thinking of it as anti-nature, only because it has grown to rival the impact and power of its home. But in its origins and fundamentals a tool is as natural as our life.
  • The gravity of technology holds us where we are. We accept our attachment. But to really appreciate the effects of technology – both its virtues and costs -- we need to examine the world of humans before technology. What were our lives like without inventions? For that we need to peek back into the Paleolithic era when technology was scarce and humans lived primarily surrounded by things they did not make. We can also examine the remaining contemporary hunter-gatherer tribes still living close to nature to measure what, if anything, they gain from the small amount of technology they use.
  • Then about 50,000 years ago something amazing happened. While the bodies of early humans in Africa remained unchanged, their genes and minds shifted noticeably. For the first time hominins were full of ideas and innovation. These newly vitalized modern humans, which we now call Sapiens, charged into new regions beyond their ancestral homes in eastern Africa. They fanned out from the grasslands and in a relatively brief burst exploded from a few tens of thousands in Africa to an estimated 8 million worldwide just before the dawn of agriculture 10,000 years ago.

  • It should have been clear to Neanderthal, as it is now clear to us in the 21st century, that something new and big had appeared -- a new biological and geological force. A number of scientists (Richard Klein, Ian Tattersall, William Calvin, among many others) think that the "something" that happened 50,000 years ago was the invention of language. Up until this point, humanoids were smart. They could make crude tools in a hit or miss way and handle fire – perhaps like an exceedingly smart chimp. The African hominin's growing brain size and physical stature had leveled off its increase, but evolution continued inside the brain.  "What happened 50,000 years ago," says Klein, "was a change in the operating system of humans. Perhaps a point mutation effected the way the brain is wired that allowed languages, as we understand language today: rapidly produced, articulate speech."  Instead of acquiring a larger brain, as the Neanderthal and Erectus did, Sapien gained a rewired brain.  Language altered the Neanderthal-type mind, and allowed Sapien minds for the first time to invent with purpose and deliberation. Philosopher Daniel Dennet crows in elegant language: "There is no step more uplifting, more momentous in the history of mind design, than the invention of language. When Homo sapiens became the beneficiary of this invention, the species stepped into a slingshot that has launched it far beyond all other earthly species." The creation of language was the first singularity for humans. It changed everything. Life after language was unimaginable to those on the far side before it.
