“In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute. It sounds weird and it is. The reason for wanting to hold light in its place (aside from the sheer awesomeness of it) is to ensure that it retains its quantum coherence properties (i.e. its information state), thus making it possible to build light-based quantum memory.”And the longer that light can be held, the better as far as computation is concerned. Accordingly, it could allow for more secure quantum communications over longer distances.Needless to say, halting light is not easy — you can't just put in the freezer. Light is electromagnetic radiation that moves at 300 million meters per second. Over the course of a one minute span, it can travel about 11 million miles (18 million km), or 20 round trips to the moon. So it's a rather wily and slippery medium, to say the least. But light can be slowed down and even halted altogether. And in fact, researchers once kept it still for 16 seconds by using cold atoms.For this particular experiment, researcher Georg Heinze and his team converted light coherence into atomic coherences. They did so by using a quantum interference effect that makes an opaque medium — in this case a crystal — transparent over a narrow range of light spectra (a process called electromagnetically induced transparency (EIT)). The researchers shot a laser through this crystal (a source of light), which sent its atoms into a quantum superposition of two states. A second beam then switched off the first laser, and as a consequence, the transparency. Thus, the researchers collapsed the superposition — and trapped the second laser beam inside.

… We began our New York meeting by trying to understand why media companies have largely failed to take advantage of the incredible power of the Web and mobile devices.We identified four forces that have stymied innovation:1. Content Management Systems. They are designed to convert old media into new media and they provide little flexibility to experiment with new journalistic forms.2. Newsroom culture. The rhythm in most newsrooms is based on a well-established work flow that produces predictable content. It’s not easy to suggest a wholesale change.3. Product managers on the business side. They’re accustomed to selling the old recipe and often seem perplexed by new approaches.4. Editors/news directors. They’ve got other priorities — such as having to choose people for another round of layoffs — and often don’t have the resources for a new venture....

BY SUSAN KENT: “Does anyone go to libraries anymore?” A mayor, the president of a major foundation, a corporate executive, and several newspaper reporters have asked me that question.[...] My answer to this question is a resounding, “Of course!” When I walk into almost any public library in any city—from my neighborhood branch in L.A. to Buffalo, New York—I see toddlers with their moms or dads, waiting for story time to begin. After school lets out, I see elementary school-age children working together on homework assignments and creating web-based reports. I see teens congregating in small groups to record digital music and videos. I see people being tutored in literacy and English or gathering for events. I overhear book club members engaged in conversation. I was a librarian for more than 40 years and served as the director of the Los Angeles Public Library, the Minneapolis Public Library, and as the chief executive of the branch libraries of the New York Public Library. Now, I consult with libraries in the U.S. and beyond about their roles and strategies for the future."

“ The theme of this year’s report is Inspiring Disruption. In it, we discuss 10 trends that exemplify the unprecedented potential for emerging technologies to reshape how work gets done, how businesses grow, and how markets and industries evolve.”
This thesis is a compendium of research which brings together ideas from the fields of Complex Networks and Computational Neuroscience to address two questions regarding neural systems: 1) How the activity of neurons, via synaptic changes, can shape the topology of the network they form part of, and 2) How the resulting network structure, in its turn, might condition aspects of brain behaviour. Although the emphasis is on neural networks, several theoretical findings which are relevant for complex networks in general are presented -- such as a method for studying network evolution as a stochastic process, or a theory that allows for ensembles of correlated networks, and sets of dynamical elements thereon, to be treated mathematically and computationally in a model-independent manner. Some of the results are used to explain experimental data -- certain properties of brain tissue, the spontaneous emergence of correlations in all kinds of networks... -- and predictions regarding statistical aspects of the central nervous system are made. The mechanism of Cluster Reverberation is proposed to account for the near-instant storage of novel information the brain is capable of.Interplay between Network Topology and Dynamics in Neural SystemsSamuel Johnsonhttp://arxiv.org/abs/1302.3943

The present work is meant as a reference to provide an organic and comprehensive view of the most relevant results in the exciting new field of Networks of Networks (NetoNets). Seminal papers have recently been published posing the basis to study what happens when different networks interact, thus providing evidence for the emergence of new, unexpected behaviors and vulnerabilities. From those seminal works, the awareness on the importance understanding Networks of Networks (NetoNets) has spread to the entire community of Complexity Science. The reader will benefit from the experience of some of the most well-recognized leaders in this field. The contents have been aggregated under four headings; General Theory, Phenomenology, Applications and Risk Assessment. The reader will be impressed by the different applications of the general paradigm that span from physiology, to financial risk, to transports. We are currently making the first steps to reduce the distance between the language and the way of thinking of the two communities of experts in real infrastructures and the complexity scientists. Although this path may prove to be long, it is extremely promising, both in extending our understanding of complex systems and in finding concrete applications that can enhance the life quality of millions of people.

In the second part of this article, I am instead looking at these other key trends: 1) Dusk of Blogs How blogs are changing their role and importance within the information ecosystem. 2) Beyond WordPress WordPress has been a revolutionary tool for small and large independent web publishers. But in its fantastic growth, it may have lost track of its true original purpose. What's there now to replace it? 3) Instant Publishing When it comes to publishing online, it's not just "ease of use" that web publishers want. Immediacy, real-time, is the new in high-demand frontier. How rapidly can you go from thinking of a promotion or a new report to actually having a professional-looking page of it online? 4) Invisible UI Just-in-time interface controls are the future. The time of multiple toolbars with tens of buttons and icons, is definitely over. The new UI is basically invisible... until you need it. 5) Design Intelligence The web design and publishing ecosystem presently doesn't allow for non-technical people to create and maintain professional-looking websites without having to heavily depend on a web design studio or agency. This is about to change. Rapidly. 6) Design Marketplaces Big opportunity ahead for those who will make it easy and efficient to find, select and organize the best web design templates available out there in a fast, easy and effective fashion.

Mike Arauz, one of the many bright strategists at Undercurrent suggests it’s time for us (digital strategists especially) to become square-shaped. He claims, “you should just know everything.” In a post on Medium , he declares that if you work at the intersection of people, business and technology — I think that would include all of us — you need “an expansive approach to cultivating your expertise.”He offers a list that might be a bit more technical than most of us want to explore, but a look at any of the emerging technologies validates his argument.Digital printers will soon let us make our own products (eye glass frames, light fixtures, toys), print clothing items (tactile screens that let us feel the material are coming), and prepare dinner (or at least dessert.) If this doesn’t change how we market, sell and distribute, it will certainly affect consumers’ expectations for customization....
