Organs on Demand | The Scientist Magazine® - Nightly RENAL RECONSTRUCTION: Wake Forest postdoctoral fellow Hyun-Wook Kang operates a 3-D printer that is making a kidney prototype with cells and biomaterials.IMAGE COURTESY OF WAKE FOREST INSTITUTE FOR REGENERATIVE MEDICINE On a stage in front of an audience of thousands, a futuristic-looking machine squirted gel from a nozzle. Layer by layer, it built up the material, shaping it into a curved, pink, kidney-shape structure based on a medical CT scan of a real organ. It was 2011, and Anthony Atala, director of the Wake Forest Institute for Regenerative Medicine, was demonstrating his progress in using three-dimensional (3-D) printing to make a kidney during his TED Talk. But Atala had not made a functional human kidney, as he at times seemed to imply and as the Agence France-Presse reported in a widely disseminated article. Atala’s kidney prototype represents both the promise of 3-D printing in a medical context and the hurdles that tissue engineers have yet to clear. Blood trouble References
The Zim 3D Personal Printer - Fabbaloo - It's another week and obviously time for another new 3D printer launch on Kickstarter. This week the Zim 3D printer launched, hoping to raise funds for its first production run. With new 3D printers launch almost daily, it is very difficult for new entrants to distinguish themselves above the other offerings. What does Zim offer? First, we must say their 3D printing mechanism is quite comparable to alternatives. This is not sufficient to distinguish Zim from other 3D printers. But we see they have explored two areas not previously addressed by other manufacturers. First, their filament management seems superior to the traditional spools dangling nearby the machine. The second area of interest is connectivity. We think the camera and app combination is terribly important. The Zim 3D project now seeks funds for their first production run. Is the Zim 3D different?
Plus une femme est intelligente, et moins elle est susceptible de devenir mère Il existe une relation inverse entre l’intelligence des femmes et leur fécondité, a établi une étude de la London School of Economics, rapportée par The Guardian. Dans son livre, The Intelligence Paradox: Why the Intelligent Choice Isn’t Always the Smart One, le psychologue évolutionnaire Satoshi Kanazawa a démontré que pour chaque tranche de 15 points de QI additionnelle, la probabilité qu’une femme ait des enfants chute de 25%. Plus les femmes sont intelligentes, et moins il est probable qu’elles deviennent mères un jour, affirme-t-il. Kanazawa a étudié les données d’une étude britannique, la United Kingdom’s National Child Development Study, et après avoir contrôlé le rôle de facteurs tels que les facteurs économiques ou l’éducation, il est parvenu à la même conclusion. Cette étude montre que le nombre de femmes sans enfants a presque doublé en Grande-Bretagne depuis 1990, et qu’une femme sur 5 âgée de 45 ans n’a pas d’enfants.
Maddie's Fund - The Dollars and Sense of Sheltering: A Tool for Financially Evaluating Your Shelter's Programs Home » Maddie's Institute » Webcasts » The Dollars and Sense of Sheltering: A Tool for Financially Evaluating Your Shelter's Programs August 2013 Sheltering isn't just about good intentions. It's about planning and developing programs that have a good chance of keeping animals healthy and happy, as well as maximizing adoptions and lifesaving. To make that happen, shelter directors and managers need to have a solid understanding of the practical and financial aspects of their programs. These are daunting prospects for many in the shelter world. Fortunately, Dr. Please join Dr. The recorded version of this webcast is available below. The information presented by Dr. This program was reviewed and approved by the AAVSB RACE program for 1 hour of continuing education in jurisdictions which recognize AAVSB RACE approval.

3DR RepRap Delta Printer - Part 1 - Release - Mini Maker-Faire London - Nightly Hello Everyone,This post sees the release of my 3DR Delta printer design. I know a lot of you have been asking for it. I had planned to do another monster post on full 3DR assembly, but as documentation is taking much more time to get completed, instead of delaying the release any further I thought it best to do a series of Blog posts to show assembly, setup, calibration, and firmware config in stages. 3DR (V2_001) Release. 3DR attracted a lot of attention for the entire Maker-Faire day, much more than I expected. Here are a few photo's of some of the objects we printed using the fine filament faberdashery provided to all exhibitors during the faire. This was a popular one - the colours mix between clear at the bottom, bands of increasing rainbow and gold eventually fading into silver. - Print time of 67mins / 0.125mm layers @ 105mm/sec 0.3mm mixing nozzle. A Joris Weekly cup (Nr22) printed in Bling Bling Gold, mixed with various rainbow colours. Special thanks to - Johann C.
FABtotum Scientists invent hydrating, hangover-free beer Getty Images/iStockphoto/Getty Images/iStockphoto The electrolytes added to the beer are much like those added to sports drinks such as Gatorade. Sunglasses and Advil might not be the only cure for a hangover these days. Australian scientists have brewed up a hangover-free beer, allowing drinkers to keep sipping while avoiding dehydration that leads to next-day hangover symptoms. Nutrition researchers at Griffith University's Health Institute added electrolytes to two commercial beers — one regular strength and light beer — before giving it to participants who had just exercised. While researchers don't suggest drinking beer after working out, the study showed that the light beer was three times more hydrating than normal beer, ABC News reports. "We know that beer is a very popular drink with people, particularly after ... sport or exertion," Associate Professor Ben Desbrow told ABC. What's the catch?
Petit Muzo a trouvé un produit de niche - Le Courrier de Saint-Hyacinthe Vous devinez ce qui s’est passé! Hugo Berthiaume, Stéphanie Kerouac et Jean-François Beauregard se sont associés pour créer leur entreprise : Petit Muzo. Faire le grand saut dans un autre domaine « Tout a commencé quand j’enseignais sur la Basse-Côte-Nord, avec une soupe aux coeurs de poulet, que j’ai donnée à mes chiens parce que ça m’écoeurait de manger ça! Eux, par contre, ils ont adoré! « Je cherchais à faire des gâteries saines, sans sel ni gras. Trois associés et leurs partenaires Jean-François Beauregard a offert d’établir la cuisine industrielle de Petit Muzo dans son ancienne demeure familiale. Tous trois sont unanimes : « Le CLD nous a beaucoup aidés et encouragés ». Des gâteries naturelles et québécoises « Nos gâteries sont uniques au Québec : naturelles, fabriquées au Québec par des Québécois et avec des produits du Québec! Ce sont des gâteries saines, sans gluten, blé ou soya, idéales aussi pour les chiens diabétiques.
Apres l'imprimante 3D, l'imprimante biologique.. Une machine à téléporter la vie ? Il a déchiffré le génome humain, crée le premier être de synthèse – une bactérie – il se prépare désormais à « téléporter la vie ». S’il y a bien un homme qui joue à se prendre pour Dieu, c’est Craig Venter. Ce chercheur controversé planche aujourd’hui sur un « convertisseur biologique digital » qui devrait permettre de télécharger des séquences d’ADN numérisées pour synthétiser artificiellement virus, protéines, et même cellules vivantes. Plutôt que d’aller en pharmacie chercher ses antibiotiques, pourrons-nous un jour « imprimer » directement nosantibiotiques depuis chez nous ? [Vidéo] Conférence TED : Craig Venter explique comment la synthèse artificielle de la vie va révolutionner la recherche en biologie Imprimer des extraterrestres ? Plus surprenant, sa machine a téléporter la vie intéresse la recherche spatiale et pourrait faire partie du nécessaire des futurs colons de la planète Mars. Source : wedemain
Mebotics The idea behind the Mebotics Microfactory began when friends who were helping grow a local makerspace, the Artisan’s Asylum, started kicking around the idea of a portable, clean and quiet hybrid manufacturing machine. The concept grew out of a shared frustration – a desire to develop functional prototypes and art pieces in our homes and business (outside of traditional machine shop space) without making a mess or driving our neighbors and spouses crazy. The company incorporated in 2012 and, over the next few years, self-financed the development if 5 versions of the machine. At Mebotics, our mission is simple: empower individuals and small business with affordable, clean, quiet, safe desktop manufacturing tools capable of working in a wide range of materials.
