re:3D — one of Austin’s newest start-ups: Gigabot with its USP is all about size: A considerable increase compared with other 3D printers at the same level.  “our project is aimed at designing the first large-format 3D printer… that you can take home with you. It’s not only about taking the amazing technology of 3D printing and amplifying it. If we’re successful, we can envision entire markets opening up to use this technology. Markets which have struggled to maintain the status quo, let alone use some of the cutting-edge technology that for the rest of the world is an overnight delivery away. We believe that by making a production-quality model of our 3D printer, and putting it in the hands of small businesses anywhere on the planet, will give them the flexibility to sustain their community, their business, and ultimately, the world we live in.”

EBN - Gerry Fay - Supply-Chain Volatility: The New Norm

EBN - Gerry Fay - Supply-Chain Volatility: The New Norm | Social Mercor | Scoop.it

Despite my years in the electronics industry, I continue to be fascinated with the global supply chain and remain amazed at its overall efficiency.

However, I also recognize the constant presence of supply-chain volatility -- a volatility that has now become the new norm impacting every supply-chain decision we make.

Contributing to this volatility is a number of macro factors that, individually and collectively, are changing the supply-chain landscape. Focusing on the top factors can put the scope of this challenge in perspective and provide us with an approach and strategy to manage through this volatility.As you would expect, my list of macro factors change as world dynamics change. However, my top three have remained constant over time and I believe that these should be on the radar of every supply-chain professional:

Global economic conditions: Not a day goes by at my company when there isn't a deep discussion of world economic conditions. One day the dialogue may be about the US economy and the anticipated effects of the sequester. On the next day, the focus may shift to China's growth rate and the following day the topic may be on productivity trends or tax policies in Latin America. These discussions are not limited to the direct impact of these issues on our company but include an expansive evaluation of how these economic conditions influence our trading and transportation partners.

Of course, you would all expect that the leadership of any global company to be constantly evaluating these issues, but my point is that all supply-chain professionals should be equally concerned with global economic fluctuations, follow these changes closely and view the evolving conditions as precursors to changes in the supply-chain landscape.

The political climate: I think we all tend to view the political climate through the prism of the politics within our own country. Unfortunately, that perspective tends to distort our interpretation of events elsewhere in the world and bias our understanding of geo-political trends. Hand in hand with the diversity of political initiatives around the world is the diversity of cultural perspectives that underscore and drive regional political dynamics.

Every supply-chain professional must work to understand and appreciate the political and cultural environment in each of the countries and regions that influence the vitality of their supply chains. This is not an easy task and requires multiple sources of informational input.

The legal and regulatory environment: The degree of global regulatory complexity is staggering and becoming more so each day. As a result, the wider the dimensions of your supply chain the greater your exposure to trade compliance risk. Understanding the detailed requirements of emerging regulations is absolutely essential to successfully navigate through the regulatory maze. However, that is easier said than done.

Too often, as new regulations go into effect, there is a lack of clarity and a cloud of misunderstanding within our industry. Proactive involvement is necessary along with the active participation of our industry associations to drive consistent standards between industry trading partners.

Of course, there are many more factors driving supply-chain volatility and my top three are really just the tip of the iceberg. Later this month, I will be presenting at the Manufacturing Supply Chain Officer Summit in Shanghai, China, and will be addressing these and other top trends affecting the electronics ecosystem in 2013.

I look forward to seeing some of you at the summit and will be sharing insights gained at the conference in future blog posts.

I look forward to your comments.

Marie Ennis-O'Connor's curator insight, March 6, 2013 7:03 AM

Abstract Adolescents with cancer often feel isolated from family and friends. Their struggle with cancer is exacerbated by the marginalization that may occur. Online social networking might reduce the sense of isolation common to these children.

We began Bingu.org in 2011 as a social network for adolescent patients ages 13-21 at Mount Sinai Medical Center’s Hematology/Oncology outpatient clinic. MSMC, located in East Harlem, provides comprehensive services to patients throughout the New York metropolitan area. Bingu.org allows teens to blog, post photos, and discover other teenagers who understand what they’re going through.

Research has shown that adolescent patients may slip through the cracks of our healthcare system. This is evident in most pediatrics clinics, where cartoonish wallpaper, arts & crafts activities, and simple toys are meant to entertain younger patients. Today’s teenagers require interaction with peers, and for many of them this means online social networking.

Although many Bingu members have a Facebook account, such a diffuse and public community may not meet their needs. Bingu – an acronym for “But I’m Not Giving Up” – allows young patients with cancer or blood disorders to connect in a secure and candid environment. The content of the site is unavailable to search engines, and new members must be approved by the site administrator. This level of security is important to allow teens to share openly and to reassure parents.

From 9/2011-4/2012, Bingu has registered 28 members. Those recently diagnosed reach out to patients in remission and ask them what to expect. Teenagers receiving chemotherapy send each other messages of support and strength. Before joining the site, almost no teen knew of other patients with a similar condition. Now they each know over two dozen.

Although there are other, larger social networks for sick children, Bingu offers a more personal environment for those who share similar conditions in the same geographical area. The personal involvement of the moderator allows attention to the cultural and economic challenges of the community in which the site is based.

Our goal is that other hospitals across the country will create their own social networks for their communities, resulting in a regional strategy for patients with similar challenges. Such sites may be created with no professional training in computer science or web design. We used the social network service SocialGo, creating Bingu using their graphical user interface and without writing a single line of code.

The greatest challenge in creating Bingu and other similar sites may be in overcoming peoples’ fears of allowing teenagers to use the internet. Such projects may meet a skeptical and nervous response from hospital administrators. There may be concerns that giving teens the ability to connect online will inevitably lead to cyber-bullying, HIPAA violations, and inappropriate relationships. These concerns are real and must be addressed, but they should not deter us from the great benefit these online communities may provide to sick children.

Future plans include expanding support for adolescents with different medical conditions, branching out to other local hospitals, and obtaining resources to provide computers for adolescent cancer patients unable to purchase their own.

Researchers trap immune cells in oil-water droplets in hopes of reprogramming them to fight cancer

Researchers trap immune cells in oil-water droplets in hopes of reprogramming them to fight cancer | Social Mercor | Scoop.it

Some biologists would like to train patients’ own immune systems to treat diseases such as cancer and autoimmune disorders. They envision programming immune cells to destroy tumor cells or to stop immune system attacks on healthy tissue. Now a team of German researchers reports a method that traps immune cells in microscopic water droplets and exposes the cells to chemical signals that could teach them the difference between friend and foe (J. Am. Chem. Soc., DOI: 10.1021/ja311588c).

 

In our immune systems, T cells play many key roles in preventing disease. They attack invaders such as viruses, help hold the immune system’s memory of past infections, and even prevent other immune cells from attacking the body’s own tissue. Joachim P. Spatz and Ilia Platzman, researchers atMax Planck Institute for Intelligent Systems, in Stuttgart, Germany, study how T cells mature and get trained in a particular task. Many types of T cells interact with antigen-presenting cells, which gather up and display fragments of proteins from viruses, bacteria, and other invaders. Through these cellular interactions, the T cells learn how to identify threats and help the immune system eliminate them.

 

Immunologists believe it will be possible to treat diseases by mimicking this process outside the body. For example, a doctor could isolate a cancer patient’s own T cells, expose the cells to antigens specific to the cancer, and then transplant the cells back to direct the immune system to attack the tumor.

 

Previously developed techniques have exposed T cells to flat, relatively rigid surfaces patterned with antigens. But some researchers think a more optimal approach would involve exposing the T cells to an environment that mimics the three-dimensional curvature and squishiness of real cells.

 

The Max Planck Institute group thought they could create such an environment by enclosing T cells within droplets of water in oil. The inner surface of these droplets contains surfactant molecules that produce a fluid and mechanically soft surface, like that of a cell membrane. The team also developed a way to anchor biomolecules to the surfactants, to mimic the surfaces of antigen-presenting cells.

 

The researchers make the droplets by mixing two streams of liquid in a microfluidic system: an oil solution of the surfactants and a water-based mixture of T cells and culture medium. When the two streams meet, droplets form, with the T-cell mixture trapped inside bubbles of surfactant. The researchers attach gold nanoparticles decorated with antigens to the water-facing end of the surfactants. These particles act like the surfaces of antigen-presenting cells. The droplets can be as small as 10 µm wide, and can hold up to six cells each.

 

In a proof of concept experiment, the scientists coated the gold particles with protein fragments known to interact with T cells. When they looked at the droplets under a microscope, they saw that the T cells adhered to the droplets’ inner surfaces. In droplets made with undecorated gold nanoparticles, the cells floated around randomly within the bubbles.

The cells can survive inside the droplets for five days, after which time Platzman believes they run out of food, since the volume of the droplets is extremely small—just a few picoliters. The researchers next plan to use these droplets to expose T cells to disease-related antigens.

Cellules immunitaires chercheurs piège huile-eau des gouttelettes dans l'espoir de reprogrammer leur lutte contre le cancer.

"Certains biologistes souhaitez former patients propre système immunitaire pour traiter des maladies telles que le cancer et les troubles auto-immunes.Ils envisagent de programmer des cellules immunitaires à détruire les cellules tumorales ou à arrêter les attaques du système immunitaire sur les tissus sains. Maintenant, une équipe de chercheurs allemands fait état d'une méthode qui piège les cellules immunitaires dans les gouttelettes d'eau microscopiques et expose les cellules à des signaux chimiques qui pourraient leur enseigner la différence entre ami et ennemi (J. Am. Chem Soc, DOI:... 10.1021/ja311588c) .

 

Dans notre système immunitaire, les lymphocytes T jouent de nombreux rôles clés dans la prévention de la maladie. Ils attaquent les envahisseurs tels que les virus, aider à maintenir la mémoire du système immunitaire des infections passées, et même de prévenir d'autres cellules du système immunitaire d'attaquer les propres tissus du corps. Joachim P. Spatz et Ilia Platzman, les chercheurs ATmax Planck Institut des Systèmes Intelligents, à Stuttgart, en Allemagne, étudier comment les cellules T matures et se former dans une tâche particulière. De nombreux types de cellules T interagissent avec les cellules présentatrices d'antigène, qui se réunissent et afficher des fragments de protéines du virus, les bactéries et autres envahisseurs. Grâce à ces interactions cellulaires, les cellules T apprendre à identifier les menaces et aider le système immunitaire à les éliminer.

 

Immunologistes crois qu'il sera possible de traiter les maladies en imitant ce processus en dehors du corps. Par exemple, un médecin peut isoler propres d'un patient cancéreux des cellules T, les cellules exposer à des antigènes spécifiques à la tumeur, puis transplanter les cellules de retour pour diriger le système immunitaire à attaquer la tumeur.

 

Techniques précédemment développés ont exposé des cellules T à des surfaces planes et rigides relativement à motifs avec des antigènes. Mais certains chercheurs pensent une approche plus optimale consisterait à exposer les cellules T à un environnement qui imite la courbure tridimensionnelle et squishiness de véritables cellules.

 

L'Institut Max Planck groupe a pensé qu'ils pouvaient créer un tel environnement en enfermant des cellules T dans les gouttelettes d'eau dans l'huile. La surface interne de ces gouttelettes contient des molécules tensioactives qui produisent un fluide et la surface mécaniquement souple, comme celle d'une membrane cellulaire. L'équipe a également développé une façon d'ancrer biomolécules aux tensioactifs, à imiter les surfaces des cellules présentatrices d'antigène.

 

Les chercheurs font des gouttelettes en mélangeant deux courants de liquide dans un système microfluidique: une solution d'huile et de tensioactifs un mélange à base d'eau des cellules T et un milieu de culture.Lorsque les deux flux se rencontrent, sous forme de gouttelettes, avec le mélange des lymphocytes T piégées à l'intérieur des bulles d'agent tensio-actif. Les chercheurs attachent des nanoparticules d'or décorées avec des antigènes à la fin l'eau face à des tensio-actifs. Ces particules se comportent comme des surfaces de cellules présentatrices d'antigène. Les gouttelettes peuvent être aussi petites que 10 um de large et peut contenir jusqu'à six cellules chacun.

 

Dans une preuve de concept de l'expérience, les scientifiques ont recouvert les particules d'or avec des fragments de protéines connues pour interagir avec les cellules T. Quand ils ont regardé les gouttelettes sous un microscope, ils ont vu que les cellules T adhéré à la surface des gouttelettes internes ». Dans gouttelettes faites avec des nanoparticules d'or non décorés, les cellules flottaient autour de hasard dans les bulles.

Les cellules peuvent survivre à l'intérieur des gouttelettes pendant cinq jours, après quoi Platzman pense qu'ils manquent de nourriture, puisque le volume des gouttelettes est extrêmement petite, juste un peu picolitres. Les chercheurs ont ensuite l'intention d'utiliser ces gouttelettes d'exposer les cellules T aux maladies liées à des antigènes".
