The Easiest, Most Horrifying Way to Create Artificial Wombs abortion. ultimately, i feel like this is how the issue of abortion will be resolved. first, a couple of ground rule, undeniable facts: 1. we do not know when human life worthy of protection - i.e. 2. it is IMPOSSIBLE to know with certainty when "personhood" begins. it will forever be the fodder for philosophical musings and never one of absolute certainty. ultimately, as it manifests in government and societies, it is a matter of pragmatism and the freedom of one party who is undeniably a person with rights - women. as with all rational people, i am pro choice. i do not believe that the 8 cells of a blastocyst are a "person" with a life worth protecting. but at the same time, what of a fetus that 8.5 months old still within the womb of its mother and yet to be born but could easily survive even without an incubator. just as i would instantly dismiss the blastocyst as human in any significant way, i would say an 8.5 month fetus is a human child. not even a iota of doubt. so: where's the line? or
Optogenetics: A wireless, optical router for your brain Ready for the Bleeding Edge Science Word of the Day? Optogenetics. It’s even weirder than it sounds, too: optogenetics is the manipulation of a cell’s functions with light (usually lasers). Today, American startup Kendall Research has announced that it has made a wireless optogenetics device that the company’s founder calls “a wireless router for the brain.” To understand the importance of optogenetics, and to marvel at the magic of hooking your brain up to a network with a wireless router, we have to first look at how researchers currently investigate cell function, and thus just how groundbreakingly different the optogenetic approach is. At the moment, the only real way to investigate animal cells is to knock out a function, usually by breeding a genetically engineered mutant. Now, back to the “wireless router” claim. As far as humans are concerned, optogenetics are probably the key to Matrix-like “I want to learn Kung Fu!” Read more at Technology Review
La nanotechnologie moleculaire, par Frederic Levy. Jusqu’à présent, toutes les méthodes de fabrication manipulent les atomes en très grande masse. Même la fabrication ultra fine des puces informatiques traite les atomes de façon statistique. Car les atomes sont extraordinairement petits par rapport à notre échelle. Par exemple, dans l’épaisseur de cette feuille de papier –je l’ai mesuré, elle fait environ un dixième de millimètre d’épaisseur–, il est possible d’empiler environ 400.000 atomes de métal. Il y a donc beaucoup de place à cette échelle ! En fait, pour en fournir une image plus concrète, Feynman avait donné l’exemple suivant : en utilisant un cercle d’une superficie de 1000 atomes par point d’impression, il serait possible d’imprimer toutes les pages de l’Encyclopedia Brittanica sur la tête d’une épingle. Le but de la nanotechnologie moléculaire, et des recherches en cours actuellement, est d’arriver à ce contrôle précis et individuel des atomes.

The Making-of Innovation » Towards Human-Centered Design The consequence of taking customer orientation serious is to integrate them right at the heart of value creation – in new product design and development. The transitions in innovation management during the last years allow us exactly to that in a more resolute way. By democratizing knowledge and information the social media revolution strongly supported the dissemination of concepts such as open innovation and co-creation and at the same time transformed people from content consumers into content producers and even co-designers. The consequence is a change in the prevailing role models of creating new products. The ability of interdisciplinary collaboration inside and outside the firm is more essential than ever before. THE CHANGING ROLE OF PRODUCT DESIGN FOR INNOVATION Industrial design is an applied science whereby the aesthetics and usability of mass-produced products are improved for marketability and production.

Could Brain Imaging Replace The SAT? Imagine it's the year 2032. You are a high school student. You are at a center where a visual scanner confirms your identity so you can enter a room where you are about to receive a brain scan. You wake up. Well, as you were sleeping, you just took the neuro version of the SAT. This fictional scenario is certainly not a reality today, but perhaps something like it may be a reality in the future. Haier paints a picture of our future: "Can it be done today? In 1988, Haier and his colleagues scanned volunteers while they attempted to solve problems from the Raven's Advanced Progressive Matrices, a nonverbal intelligence test. In other words, smarter people had brains that could be more efficient. Since that landmark study, the field of has started to take off. In Haier's words, "There was a network distributed around the brain that was related to intelligence, which we named the Parieto-Frontal Integration or P-FIT theory. Says Haier, "That's kind of a no brainer." © 2012 by Jonathan Wai
3 Ideas That Are Pushing the Edge of Science | Gadgets 1 Sperm-powered Nanobots The next wave in health care may include a brigade of medical nanobots, devices tiny enough to ride the flow of blood through the body's arteries to a problem area. The bots might arrive at a clot, for example, and then using an internal power system, obliterate the clot with a precisely targeted drug or therapy. Designing a power source to accomplish such a task has been a challenge, but from the College of Veterinary Medicine at Cornell University comes a possible answer. The same molecular power packs that fuel sperm in their journey through the uterus and to a fallopian tube might be copied and used to keep the nanomachines running once they reach their targets. Led by reproductive biologist Alex Travis, the engineering effort focuses on a chain of enzymes that metabolize glucose molecules into the biological fuel ATP (a process known as glycolysis), which enables sperm locomotion. Does this mean we could actually experience a second dimension of time?
U.S. Spies See Superhumans, Instant Cities by 2030 | Danger Room Artificial limbs like these could be only the beginning of man-machine interfaces, the National Intelligence Council predicts. Photo: DoD 3-D printed organs. Brain chips providing superhuman abilities. Megacities, built from scratch. Every four or five years, the futurists at the National Intelligence Council take a stab at forecasting what the globe will be like two decades hence; the idea is to give some long-term, strategic guidance to the folks shaping America’s security and economic policies. We’ve seen experimental prosthetics in recent years that are connected to the human neurological system. And if the machines can’t be embedded into the person, the person may embed himself in the robot. The Council’s futurists are less definitive about 3-D printing and other direct digital manufacturing processes. But not all of these biological developments will be good things, the Council notes. Unlike some Congressmen, the Council takes climate change as a given.
Hello 3 - Jambe et fibre optique : petit co Hôpital La Musse, Saint Sébastien de Morsent (Eure) - Samedi 1er août 2009 Plaidoyer pour fibrer la France par emprunt d'Etat (on a des idées fixes ou en en a pas...) Comme je vous l'ai raconté dans mon premier post Hello, cela a pris 7 heures, voir un peu plus, entre le premier coup de fil donné par mon fils aux autorités sanitaires, et mon arrivée sur une table d'opération. "7 heures, m'a dit mon chirurgien, c'est beaucoup pour une jambe qui n'est plus irriguée normalement". Effectivement, j'ai dû subir l'amputation suite à cet anévrisme poplié.Je lui ai demandé à son avis, qu'elle aurait été la durée limite pour "rattraper" la jambe. Supposons maintenant que le territoire national ait été couvert par un réseau de télécommunications à TRES haut débit (100 mégas symétriques, voir, ne mégotons pas, 1 giga). Donc mon problème de jambe survient. Que faire ? Surtout n'allez pas croire que j'en veuille aux pompiers, aux ambulanciers, aux médecins de garde, aux internes... Et les USA ? Note 1.
Human-Centered Design Toolkit For years, businesses have used human-centered design to develop innovative solutions. Why not apply the same approach to overcome challenges in the nonprofit world? This project, funded by International Development Enterprise (IDE) as part of a grant from the Bill & Melinda Gates Foundation, sought to provide NGOs and social enterprises with the tools to do just that. The HCD Toolkit was designed specifically for NGOs and social enterprises that work with impoverished communities in Africa, Asia, and Latin America. The HCD toolkit has been used by organizations throughout the developing world, including Acumen Fund, AyurVAID, Heifer International, ICRW, IDE, Micro Drip, and VisionSpring. “Many thanks to IDEO for their Human-Centered Design Toolkit, which served as a guide for our work.” “An impressive study intended to create a common language around designing for social impact.
Ultrasound Helmets Control Brain Activity Scientists at Arizona State University in Tempe, Arizona are exploring the use of ultrasound to stimulate brain activity without the invasive procedures or internal implants required for current electrical stimulation methods. In addition to treatment of neurological diseases like Parkinson’s disease, they are exploring military applications of direct brain stimulation using ultrasound devices placed inside helmets worn by soldiers. The helmets could help improve and retain soldier alertness levels for extended periods of time, provide pain management assistance in the field, reduce stress, and protect against traumatic brain injury. A team led by Dr. Prototypes of the transcranial pulsed ultrasound devices can fit inside helmets. Civilian uses of the technology include treatment of diseases like Huntington disease and Parkinson’s disease by specifically targeting very localize portions of damaged brain tissue.
It Is Almost Impossible To Create Fake Meat Electronic brain hacks are turning insects into robotic helpers We're a long way from directly controlling human minds remotely, but recent years have seen a string of breakthroughs in hacking the minds of insects. Insect brains are probably the simplest interesting brains, as insects can perform a range of tasks (flying, smelling, carrying, etc.) with brains that have numbers of neurons orders of magnitude less than those in complex vertebrates. A fruit fly has around 100,00 neurons, compared to 85 billion in humans. So at the conjunction of neuroscience and robotics lie insects -- their tiny brains still too complex to model completely, but offering an easy way into modelling certain parts of the brain. The hope is that the bee-bot could fly in areas that other robots can't fit, like a collapsed building. A lot of research in the area of bug brains is being funded by the US Defense Advanced Research Projects Agency (Darpa), the Pentagon agency which seeks out new technologies for military use.
La 3ème Révolution d'Homo Sapiens... L'Inte Le passé c'est bien, mais le futur c'est mieux. Pourquoi ? Parce que c'est là où nous allons passer notre vie (je crois que cet adage est de ma pomme ? Depuis la nuit des temps, Homo Sapiens est une créature "bricolée" par Dame Nature (ou Dieu le Père ?). Je pense que les 30 prochaines années vont être - comment dire - assez sportives... Prenons un peu de hauteur, voulez-vous ? Il me semble qu'aujourd'hui tout est en place pour que les Homo Sapiens démarrent une 3ème grande Révolution... Il y a 7 millions d'années environ, nous avions un ancêtre commun avec les primates (le fameux chaînon manquant, que l'on a toujours pas trouvé). Voilà pour le très loin... Selon la théorie actuelle admise par de nombreux paléontologues (dont Yves Coppens), les premiers spécimens d'Homo Sapiens seraient donc apparu en Afrique de l'Est il y a environ 150.000 ans, suite à un accident géologique (la grande faille du Riff) qui s'est produite bien avant, et qui a conduit à une modification du climat local.
