‘Connecting the dots’ for quantum networks Explore further Recently, some approaches have suggested “rediscovering” old techniques such as analog computing, which usually lie outside the usual qubit architecture, in the hope of finding new pathways to experimentally realize quantum computation. For instance, using analog techniques and the quantum properties of atomic clusters called Bose-Einstein condensates, a team of researchers from Japan has recently improved upon a classical factoring algorithm.“Any algorithm where the output is continuous rather than divided into bits (as on a digital computer) is analog,” Mark Sadgrove of the Japan Science and Technology Agency (JSTA) told PhysOrg.com. “In our case, we measure quantities which are continuous in principle. By this I mean that the energy or the probability to find an atom with a given momentum are continuous variables, in theory. In practice, we use a finite number of atoms, so in some sense the final outputs are discrete, but theoretically the result of the computation is analog in nature.”Sadgrove and his colleagues Sanjay Kumar of the University of Electro Communications (UEC) in Chofushi, Chofugaoka, and Ken’ichi Nakagawa, who has affiliations with both JSTA and UEC, have demonstrated that, compared with the classical implementation, their method can distinguish more accurately between factors and non-factors of large numbers. Specifically, their quantum system could increase the accuracy of a classical algorithm called the Gauss sum algorithm, a technique pioneered by Wolfgang Shleich of Ulm University in Germany.Their quantum system consists of thousands of rubidium-87 atoms that are cooled to near absolute zero to form a Bose-Einstein condensate (BEC). At such a low temperature, the atoms’ wavelengths increase and overlap, so that the cluster becomes a single quantum state and obeys quantum laws, yet has a relatively large size. The physicists zapped the BEC with a brief light pulse composed of two counter-propagating beams. They programmed one beam to have phase jumps (to displace the beam’s wavelength), while the second beam had no phase jumps. Programming the first beam served as the input method, representing an integer to be factored. (PhysOrg.com) — Theoretically, quantum computing has the potential to work more efficiently and accurately than classical computing for certain processes, such as factoring. But quantum methods are experimentally challenging, since they often require tiny, fragile systems that are difficult to handle.

The content is provided for information purposes only. The dynamics of the atoms subject to the pulse could then be used to perform factoring calculations. After applying the pulse, the researchers allowed the BEC to expand freely for 14 ms. They then took an absorption image of the BEC, which showed that the pulse had separated the atoms in the BEC into different momentum orders. The atoms formed a diffraction pattern, based on the relative number of atoms in each momentum order, which the physicists could interpret as the “factoring signal.” Specifically, high-momentum atoms represented factors, and low-momentum atoms represented non-factors.“You can think of the laser beam as containing the software (encoded by phase jumps) and the atoms as providing the hardware (their natural dynamics in response to the light field is what actually calculates the Gauss sum),” Sadgrove explained.In contrast to the usual Gauss sum, which is fundamentally limited in its accuracy, the quantum method significantly outperformed the classical method, in some cases doubling the atomic visibility and offering near-perfect factoring. “In our case, our current method is still slow – it doesn’t make factoring easy,” Sadgrove said. “What we showed is that quantum mechanics offers an unexpected improvement to the Gauss sum method, overcoming a fundamental accuracy limit. If the atoms behaved classically, there would be no enhancement.”The researchers noted that the higher accuracy comes at a cost of requiring more atoms, so the quantum method’s efficiency is about the same as that of the classical method. Nonetheless, as Sadgrove explained, the method offers a novel experiment in a field in which experiments are difficult to realize.“You might know that everyone doing research in quantum information is excited about [Peter] Shor’s algorithm for quantum factoring,” Sadgrove said. “Shor found a remarkable way to factor numbers using the quantum properties of interference and entanglement, which offers amazing savings in the time it takes for factoring a number. But Shor’s algorithm is hard to implement. It’s only been done successfully for up to the number 15 at the moment, and some people don’t even consider that to be a real test due to some details about the way the algorithm works. So that’s the current state of play regarding quantum factoring.”He added that researchers continue to investigate Shor’s algorithm because of its potential impact on security: “In terms of applications, there’s just one, but it’s very important. If you could do real quantum factoring, then the RSA encryption used to do secure transactions in public situations would be no good anymore. That’s because it relies on the fact that factoring large numbers is a hard problem. But quantum factoring makes it easy.”In the future, the physicists hope to use entangled systems as a factoring method, which they say the present scheme is ideally suited for. They also plan to investigate the use of multiple, correlated atomic ensembles to perform factoring of different integers simultaneously. “We would also like to extend the method beyond factoring,” Sadgrove said. “We can actually compute general ‘exponential sums’ with this method. A Gauss sum is a simple example of an exponential sum, as is a Fourier transform, which can be used to extract information about a signal. These so called ‘exponential sums’ are intricately tied to the most interesting parts of number theory, such as the distribution of prime numbers, which is still unknown. We think there may be other powerful applications of exponential sums apart from factoring.”More information: Sadgrove, Mark; Kumar, Sanjay; and Nakagawa, Ken’ichi. “Enhanced Factoring with a Bose-Einstein Condensate.” Physical Review Letters, 101, 180502 (2008).Copyright 2008 PhysOrg.com.

Image: Institution of Mechanical Engineers The engineers from Britain’s Institution of Mechanical Engineers (IME) have asked their government for an investment of 10 million pounds (around 16.3 million dollars) in these ideas to counter the threat to Britain posed by global warming. One of the authors of the report, Dr Tim Fox, said geo-engineering techniques could buy us a few extra years’ breathing space while we transition to a low-carbon world, and may help ward off the climate change scenarios we fear. The report claimed global temperatures could rise by as much as 6°C in the next 90 years if we don’t act soon, and the results would include major refugee movements as well as food and water shortages. Algae-coated buildings. Image: Institution of Mechanical Engineers One proposal was the building of forests of artificial trees. Each synthetic tree could capture up to 10 tons of CO2 a day, which is thousands of times more than a real tree. Each tree would cost around $24,400, and a forest of 100,000 of them could be constructed within the next couple of decades using existing technologies. A forest that size would be able to remove 60% of the UK’s total CO2 emissions. Globally, forests of five to ten million trees could absorb all the CO2 from sources other than power plants.The trees would have a special synthetic filter that absorbs carbon dioxide. When the filters had absorbed their load of CO2 they would be replaced with new filters and the old ones would be stored in empty gas and oil reservoirs, such as depleted oil wells in the North Sea. The trees are already at the prototype stage and their design is well-advanced. The prototype is the size of an average shipping container.Another proposal put forward by the study was to install transparent tubes filled with algae on the outside of buildings. The “algae based photobioreactors”, as they call them, would absorb carbon dioxide from the atmosphere, and could later be turned into charcoal, which could then be buried to trap the carbon dioxide. Reflective buildings. Image: Institution of Mechanical Engineers (PhysOrg.com) — A new study on how technology could help to regulate climate change has studied hundreds of ideas, and selected three considered practical and able to be implemented quickly. The report’s authors propose the construction of forests of artificial trees and installing tubes of algae on the sides of buildings to absorb carbon dioxide. They also proposed painting the roofs of buildings white to keep the Earth cool by reducing the amount of solar radiation absorbed.

Cities can be up to 4°C hotter than suburban areas, and reflective roofs could reduce the need for cooling and save up to 60% of a building’s energy use.Dr Fox warned that geo-engineering ideas such as those proposed are not a silver bullet that will solve all the problems, and they would need to be used in conjunction with other measures such as reducing our emissions and adapting to changes in the climate.More information: Read the full Institution of Mechanical Engineers report© 2009 PhysOrg.com Plant a tree and save the Earth?

The animal, with its giraffe-like long neck and long forelimbs is the first well-preserved Early Cretaceous brachiosaurid dinosaur to be discovered in Asia. It lived about 100 million years ago. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Brachiosaurs were herbivorous dinosaurs belonging to the sauropod family, but in comparison to some brachiosaurs, the new species, Qiaowanlong kangxii, is quite small, at only around 10 feet tall and close to 40 feet long. It weighed a mere 10 tons.The new brachiosaur specimen was described by authors Hai-Lu You and Da-Qing Li, in a paper published online on 4 September 2009, in the Proceedings of the Royal Society B. The brachiosaur was given the scientific name Qiaowanlong kangxii from Qiao (bridge), wan (bend in a stream), long (dragon), in reference to the area where it was found, and Kangxi, a Qing Dynasty Emperor who is supposed to have dreamt about the scenic Qiaowan region.The specimen was found in the Yujingzi Basin in Gansu Province in North West China, at an excavation site in which many other dinosaur fossils have been found in recent years, including at least three new species.Earlier studies into sauropods suggested the animals held their necks straight out, and swung them from side to side, rather like a metal detector, but the Chinese scientists found the brachiosaur skeleton had a similar bifurcated (two-part) spine to those in other sauropods, but not previously found in brachiosaurs. The bifurcated spine and the structure of the other bones discovered, including a unique pelvis, suggest the neck “should have been held aloft, with a more vertical than horizontal behavior,” according to Hai-Lu You. Having long forelimbs and a long neck held aloft, would have made it look a little like today’s giraffes, and like them, the brachiosaur would have grazed vegetation high above the reach of its competitors for food.Sauropods were thought to have been most populous in the Jurassic in Africa and North America, but some paleontologists have theorized their population declined rapidly early in the Cretaceous period. The new finding casts doubt on this theory, since a growing number of Early Cretaceous sauropods is being discovered in China.Dr Jerry Harris, Dixie State College’s Director of Paleontology, who worked with the Chinese scientists, explained that what makes the discovery so important is how it adds to our knowledge about how dinosaur populations could move around the globe in the Early Cretaceous period. Land bridges between the continents were vanishing at this time, but as the new brachiosaur has similarities to dinosaur remains found in North America, Harris suggests some connections did still exist if only sporadically. The dinosaurs took advantage of the land bridges to move around, which explains why Chinese and American brachiosaurs appear to be closely related.More information: The first well-preserved Early Cretaceous brachiosaurid dinosaur in Asia; Hai-Lu You, Da-Qing Li; Proceedings of the Royal Society B; doi: 10.1098/rspb.2009.1278© 2009 PhysOrg.com
A Pallas’s long-tongued bat, representing one of six species used in the new study. Bat researchers from the biology departments of the University of Western Ontario and the University of Regina (Saskatchewan, Ca) theorized that the amount of ethanol in the fermented fruit and nectars that the bats ingested was likely to induce intoxication.The researchers gave “sobriety tests” to 106 bats, representing six species of New World Leaf-nosed bats, after the bats had consumed enough ethanol to bring their blood alcohol content (BAC) up to 0.3 or higher. (The legal limit of BAC for human drivers is .08!) The bat BAC levels were attained by feeding the test bats ethanol mixed with sugar water. Their control group counterparts received just the plain sugar water.The bats took flight in a researcher-constructed obstacle course in which the bats would have to navigate according to five standard identifiable flying behaviors of phyllostomide bats. Otherwise, they would betray their drunkenness. Additionally, the biologists expected the alcohol to alter the bats’ echolation, or calling behavior, so they recorded the bats with ultrasonic condenser microphones.”We went into the study fully expecting that some of the species wouldn’t be able to hold their drink,” study co-author Brock Fenton, from the University of Western Ontario, told National Geographic News.But once the bats went through the test – some, mind you, with three times higher BAC than a drunk driver – the researchers found no measurable change in either flight or calling behaviors. A prior study conducted with Old World bats dieting on seasonal fruit and nectar reported signs that bat motor skills and echolation were clearly affected by the ethanol content in their diets. Apparently, the New World bats, exposed to high-ethanol products all year round, have developed an alcohol tolerance that has “afforded them an evolutionary edge.” Fenton and his colleagues are now trying “to find a company that sells alcoholic refreshments who will sponsor an expanded study.” (PhysOrg.com) — New World Leaf-nosed bats (Chiroptera Phyllostomidae) are thriving in the tropical forests of Central and South America, even though their diets consist of more fruits and nectars than their counterparts in the Old World. Strange thing is the phyllostomide bats are drawn to fruits and nectars even after they have fermented.

3. Any sufficiently advanced technology is indistinguishable from magic.Following Itskov’s keynote on the first day of the Congress, the late Dr. James Martin, who tragically passed away on June 24, 2013, gave a sweeping, engaging talk on The Transformation of Humankind—Extreme Paradigm Shifts Are Ahead of Us. An incredibly prolific author of books on computing and related technology, Dr. Martin founded the Oxford Martin School at Oxford University – an interdisciplinary research community comprising over 30 institutes and projects addressing the most pressing global challenges and opportunities of the 21st century. Dr. Martin – in the highly engaging manner for which he was renowned – presented a remarkably accessible survey of the interdependent trends that will increasingly threaten humanity over the coming decades. Dr. Martin made it disturbingly clear that population growth, resource consumption, water depletion, desertification, deforestation, ocean pollution and fish depopulation, atmospheric carbon dioxide, what he termed gigafamine (the death of more than a billion people as a consequence of food shortage by mid-century), and other factors are ominously close to their tipping points – after which their effects will be irreversible. (For example, he points out that in 20 years we’ll be consuming an obviously unsustainable 200 percent of then-available resources.) Taken together, he cautioned, these developments will constitute a “perfect storm” that will cause a Darwinian survival of the fittest in which “the Earth could be like a lifeboat that’s too small to save everyone.” However, Dr. Martin also emphasized that there are solutions discussing the trends and technologies that – even as he acknowledged the resistance to implementing or even understanding them – could have a positive impact on our future:The Singularity and an emerging technocracyGenetic engineering and Transhumanism, in particular, a synthetic 24th human chromosome that would contain non-inheritable genetic modifications and synthetic DNA sequences Artificial Intelligence and nanoroboticsYottascale computers capable of executing 1024 operations per secondQuantum computingGraphene – a one-atom thick layer of graphite with an ever-expanding portfolio of electronic, optical, excitonic, thermal, mechanical, and quantum properties, and an even longer list of potential applicationsAutonomous automobilesNuclear batteries in the form of small, ultra-safe and maintenance-free underground Tokamak nuclear fusion reactorsPhotovoltaics that make electricity more cheaply than coal Capturing rainwater and floodwater to increase water supplyEco-influence – Dr. Martin’s term for a rich, enjoyable and sometimes complex way of life that does no ecological harm”We’re capable of creating a future which is enormously better than the present we live in today,” Dr. Martin said. “What I’m doing is trying to make that happen, as far as one person can.” His words, legacy and generosity of spirit are how we all must remember him.

Dr. Peter H. Diamandis: We are evolving into meta-intelligence group-minds. Courtesy of GF2045 Avatars, androids and robotics were much-discussed topics at GF2045, and these intersected in the presentation given by Dr. Hiroshi Ishiguro, Director of the Intelligent Robotics Laboratory in Osaka, Japan, The Future Life Supported by Robotic Avatars. Ishiguro creates human-like robots rich in features that support effective relationships with humans. In particular, his Geminoid Teleoperated Androids are based on his research into the experience of presence – the feeling of human existence on our physical proximity and interactions – and the capability to transfer or reproduce the human presence through technology. (In fact, in his talk Ishiguro described how he often sends his personal Geminoid HI-2 to remote locations, allowing him to teach classes, give lectures and attend meetings via telepresence.) In addition to the highly photorealistic, lifelike Geminoid, Ishiguro has developed many other humanoids and androids, including Robovie, Repliee, Telenoid, and Elfoid.

Courtesy of GF2045 “These three challenges offer a new perspective on how we consider concepts such as what is natural to be human and how far we can go in human enhancement in order to still be a person,” Vita-More continues. “Also, it objectifies the body as a sensory-adept transportation and communication system for the brain and mind. However, before my concept of a whole-body prosthetic system is less threatening to society, there needs to be more awareness of the need for prosthetics replacement parts for the body and the extreme need for organ transplants, and that in order to preserve human well-being, we need to provide sufficient knowledge to the public these requirements. In other words” she adds, “we have to be aware that if we want to be healthy and protect ourselves from the damages of disease, we need to protect our biological bodies and be as healthy as possible for as long as possible – and if we want to continue living, we might bet benefit from opting for technological advances in the development of my vision of a whole-body networked prosthetic.”Vita-More emphasizes that addressing these challenges will require significant scientific, technological, cultural, and other developments, including greater advances in neuroscience, cognitive science, information technology, and human-computer interaction. “In other words” she says, “the body is a necessary component of personal identity – as our transportation vehicle and our sensory system – that provides data to the brain in order to be a sentient and sapient being. However,” she cautions, “science and technology are only part of the puzzle. Design is essential because its function or purpose is to identify and solve problems – a process known as need-finding.”The second aspect of design, Vita-More continues, “is to resolve the need in an iterative process until a viable outcome is developed, followed by iteratively testing that outcome. In a sense,” she notes, “design is never fully completed or finished. Rather, it can be seen as a work in progress that continues to take advantage of new tools and methods.”That said, Vita-More notes that there are two immediate developments needed to address the challenges of designing and building platform-diverse bodies that benefit from semi- and non-biological devices implanted or wearable systems: how to backup the brain and transfer it into these bodies, and how to present this idea to society so that it is understood as a an alternative to a biological body. ‘The central issue is a cultural bias that the person would be a robot or cyborg, which is a misunderstanding of terms. Instead,” she concludes, “the person would be a transitional human – still a humane, empathic, passionate person – but not 100% biological.”Towards that end, Vita-More is creating a transdisciplinary Human Enhancement Design (HED) educational program, that explores biotechnology and genomics, nanotechnology and nanomedicine, information technology and Artificial General Intelligence, robotics and smart prosthetics, neuroscience and cognitive sciences, consciousness studies and ethics, and other areas that pertain to issues of backing up the brain and whole body prosthetics. Moreover, as an ecological system comprising humans and the environment, HED explores ways to improve our relationship with the environment, extend lifespan, and map the future of human-computer interface devices. Dr. Hiroshi Ishiguro: Robot Science Made in Japan. Courtesy of Japan Society The development of brain-computer interfaces (BCIs) to allow paralyzed individuals to control various external prosthetic devices, such as a remote robotic arm, was another key topic at GF2045. UC Berkeley researchers Dr. Jose Carmena (Associate Professor of Electrical Engineering and Neuroscience, Co-Director of the recently-launched multidisciplinary Center for Neural Engineering and Prostheses, and Principal Investigator at the Brain-Machine Interface Systems Laboratory) and Dr. Michel Maharbiz (Associate Professor in the Department of Electrical Engineering and Computer Science, Co-Director of the Berkeley Sensor & Actuator Center, and member of the Center for Neural Engineering and Prostheses) addressed this topic in their joint presentation, Brain Control of Prosthetic Devices: The Road Ahead. A very recent example of the BCI research Carmena and Maharbiz discussed is Neural Dust: An Ultrasonic, Low Power Solution for Chronic Brain-Machine Interfaces3, a theoretical pre-print paper by Maharbiz, Carmena, lead author Dongjin Seo, Jan M. Rabaey, and Elad Alon published in July 2013. The paper proposes neural dust – thousands of ultra-miniaturized, free-floating, independent sensor nodes that detect and report local extracellular electrophysiological data – with neural dust power and communication links established through a subcranial interrogator. With the purpose being to enable “massive scaling in the number of neural recordings from the brain while providing a path towards truly chronic BMI,” the researchers’ goal is “an implantable neural interface system that remains viable for a lifetime.” The paper explores “the fundamental system design trade-offs and ultimate size, power, and bandwidth scaling limits of neural recording systems built from low-power CMOS circuitry coupled with ultrasonic power delivery and backscatter communication.” Dr. Michel Maharbiz: Complete single interrogator, single neural dust power and communication through link models. Source: arXiv:1307.2196v1 To accelerate their work, GENI Lab is running a crowdfunding campaign to secure additional support using Indiegogo as their crowdfunding platform. “We chose Indiegogo,” Goertzel points out, “because it’s a big-time, recognizable brand, but provides more flexibility in how you structure and manage your campaign than other crowdfunding engines.” He adds that their Indiegogo project has already been mentioned on KurzweilAI, Next Big Future and other sites – and that Adam Z1 and an updated DeSTIN paper10 to be presented at the Sixth Conference on Artificial General Intelligence (AGI-13) at Peking University on July 31 – August 3, 2013.When considering the emergence of powerful human-like Artificial General Intelligence that may well evolve its own emotional responses and values, an important and hotly-debated question is whether or not it is possible – and if so, how – to create ethical machines. In Making Minds Morally: the Research Ethics of Brain Emulation, Dr. Anders Sandberg – a Computational Neuroscientist, and James Martin Research Fellow at the Future of Humanity Institute at Oxford University, and Research Associate at the Oxford Neuroethics Center – addressed the social and ethical impact of cognitive enhancement and whole brain emulation. “We want to get to the future,” Sandberg said in his talk, “but that implies that the future had better be a good place. Otherwise, there wouldn’t be a point in getting there – but that would mean in turn that the methods we’re going to use to get to the future had better be good as well.” Sandberg went on to describe his approach of being ethically proactive as it applies to the 2045 Avatar Project and questions of death and identity. 64 channel silicon-based neural probes with nanoscale leads.

Courtesy of RSLSteeper Although Dr. Ben Goertzel, leading Artificial General Intelligence (AGI) Researcher and Founder of the OpenCog AGI project5,6, and Robotics Designer & Researcher Dr. David Hanson were scheduled to introduce GENI Lab and the Adam Z1 Genius Machine intelligent robot project at GF2045, their talk unfortunately encountered a scheduling conflict. However, Goertzel and Hanson were in attendance at the conference and were able to informally discuss their work with many attendees, and briefly present Adam Z1 to some, after the conference. The GENI Lab team – Goertzel, Hanson, Robotics Physicist Mark Tilden, and Consciousness and Design Researcher Gino Yu – are focused on creating and broadly disseminating intelligent robots, and conducting R&D aimed ultimately at the production of robots with greater-than-human consciousness, creativity, and compassion. A non-profit organization, GENI Lab embraces open source, open standards, and open collaboration to integrate adaptive intelligence, social and emotional interaction, and life-like mechanical controls and bodies. GENI Lab’s central medium-term goal is the creation of a life-sized humanoid robot with a realistic, emotional face and personality a fluidly moving body, based on the integration of analog, digital and mechanical control the ability to communicate about its physical environment and its tasks and behaviors therein the capability of simple but socially and emotionally appropriate communication in natural language Their short-term work with Adam Z1 and other robots is being pursued in the interest of this goal. The core adaptive general intelligence technology underlying GENI Lab robots rests largely on. Goertzel’s OpenCog architecture, and integrates the Hanson Robotics APIs and the DeSTIN machine vision system (initially developed at University of Tennessee at Knoxville by Itamar Arel7). “For example,” Goertzel told Phys.org, “our pattern recognition software identifies patterns in DeSTIN’s interpretation of visual scenes observed by a robot’s camera, and feeds these patterns into OpenCog.”A key aspect of GENI Lab’s approach is overcoming the limitations of current robotics technology by creating robots that elicit rich social and emotional interactions from humans. “To this end,” Goertzel says, “we overhauled OpenCog’s motivational and emotional system, creating a new system called OpenPsi8,9 gives OpenCog a more human-like emotional makeup.” (OpenPsi is modeled on Joscha Bach’s MicroPsi AI system, which is based on German psychologist Dietrich Dörner’s Psi model of mind.)In essence, Goertzel notes, Adam Z1 will be unique on two ways. “Internally, he will be the first robot that integrates deep learning- based visual perception with symbolic logical reasoning. Behaviorally, our main goal is for him to engage in creative social play like a young child. A good example would be: If you ask him to “Build me something I haven’t seen before,” he would remember what he’d seen you see, and then build you something different, While a smart three year old could accomplish this seemingly simple task – which integrates visual perception, movement, theory of mind and social interaction, and planning – no robot today can. “Further down the road,” he adds, “we would like the robot to be the first one to pass the standard preschool IQ test without any special test-specific training.”Within this framework, Goertzel continues, there are many R&D challenges to address. “One of these challenges is to successfully get vision and audition received from the robot sensors to work effectively with OpenCog’s symbolic reasoning. Another is doing natural language comprehension effectively via speech input – and given the mediocre state of current speech-to-text software, the system will have to use its emerging cognitive understanding to compensate for the ambiguities and errors in the output of speech to text software. A third challenge is optimizing the OpenCog core system for real-time processing at the speed needed for intelligent robot control, given that the robotics context involves a lot more data than the virtual-agent context we’ve mostly been dealing with lately.”The robot Adam Z1, as designed by Hanson (a former Disney sculptor and Imagineer), is cute in a toy-like sense, rather than having a more human appearance. “We did this to remain on the right side of the so-called Uncanny Valley – that is, to appeal to human emotions without creeping anyone out,” Goertzel explains. “Also, its intelligence is going to be human-like rather than precisely human, so it seems appropriate that its appearance has the same quality.” © 2013 Phys.org.

It is, strictly speaking, a real factor in scientific research.1 Futurists, visionaries, scientists, technologists, philosophers, and others who take this view to heart convened on June 15-16, 2013 in New York City at Global Futures 2045 International Congress: Towards a New Strategy for Human Evolution. GF2045 was organized by the 2045 Strategic Social Initiative founded by Russian entrepreneur Dmitry Itskov in February 2011 with the main goals of creating and realizing a new strategy for the development of humanity – one based upon our unique emerging capability to effect self-directed evolution. The initiative’s two main science projects are focused largely on Transhumanism – a multidisciplinary approach to analyzing the dynamic interplay between humanity and the acceleration of technology. Specifically, the 2045 Initiative’s projects seek to (1) enable an individual’s personality to be transferred to a more advanced non-biological substrate, and (2) extend life to the point of immortality – and those skeptical about the likelihood of achieving these goals should consider Arthur C. Clarke’s laws of prediction2: 1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. 2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. Dr. Anders Sandberg: What kind of humanity should we want to make? Courtesy of TEDxTalks Dr. Natasha Vita-More, designer and author, professor at the University of Advancing Technology, and currently Chairman of Transhumanist organization Humanity+, presented her vision of building platform-diverse bodies that could be mind-driven avatars for parlaying our personas within computational systems and telepresence in Substrate Autonomous, Networked Avatar Bodies by Design. “The three biggest challenges to implementing my vision for Bodies by Design are located within the complex sphere of social awareness,” Vita-More tells Phys.org. Specifically, she explains, these are the beliefs that the human body should be strictly biological; the brain will not, at some point, be backed up and transferable to a non-biological bodily system; and if a brain were backed up and transferred to a non-biological bodily system, it would be the same identity or person as the biological system. “To this end,” she adds, “I think that within the next five years we will see academic courses focused on the Transhumanist worldview, on my work and research in whole-body prosthetics, and significant competition amongst engineers and designers building whole-body prosthetics. In addition, anyone who wants to contribute to Bodies by Design can contact me at Natasha Vita-More Projects.” More information: The world according to Itskov: Futurists convene at GF2045 (Part 2)1Cosmic Religion: With Other Opinions and Aphorisms (1931) by Albert Einstein; also in Einstein on Cosmic Religion and Other Opinions and Aphorisms (2009) by Albert Einstein (Kindle version) 2Hazards of Prophecy: The Failure of Imagination in the collection Profiles of the Future: An Enquiry into the Limits of the Possible (1962, rev. 1973, this edition published 2000) 3Neural Dust: An Ultrasonic, Low Power Solution for Chronic Brain-Machine Interfaces, arXiv:1307.2196v1 (PDF) 4Multiplexed, High Density Electrophysiology with Nanofabricated Neural Probes, PLoS ONE 6(10): e26204 (2011), doi:10.1371/journal.pone.0026204 (PDF) 5OpenCog: A Software Framework for Integrative Artificial General Intelligence, Proceedings, AGI-08, Memphis 6OpenCogBot: Achieving Generally Intelligent Virtual Agent Control and Humanoid Robotics via Cognitive Synergy, Proceedings, International Conference on Artificial Intelligence (ICAI) 2010, Beijing (PDF) 7DeSTIN: A Scalable Deep Learning Architecture with Application to High-Dimensional Robust Pattern Recognition, Proc.

Nocera (Phys.org)—Harvard Chemist Daniel Nocera has announced during a lecture at the Energy Policy Institute in Chicago, that he and his colleagues have engineered a bacterium that has made it capable of taking in carbon dioxide and hydrogen, and excreting several types of alcohol fuels, along with biomass that can be burned and used as an energy source. During the talk, he claimed that a paper he and his colleagues have written regarding the work will soon be published in the journal Science. Bionic leaf: Researchers use bacteria to convert solar energy into liquid fuel Citation: Engineered bacterium inhales carbon dioxide and hydrogen and excretes fuel alcohols (2016, May 31) retrieved 18 August 2019 from https://phys.org/news/2016-05-bacterium-inhales-carbon-dioxide-hydrogen.html © 2016 Phys.org Nocera achieved a level of notoriety five years ago, when he and his team announced that they had created an artificial leaf that could be used to generate hydrogen for use as a fuel—that idea did not lead to hydrogen fuel cells displacing gasoline in automobiles, as he had hoped, so this go round, he has set his sights or providing a fuel source for those more in need—parts of India where there is still no electricity.The new bacterium, which has been named Ralston eutropha was first caused (via genetic engineering) to take in carbon dioxide and hydrogen, which it used to produce adenosine triphosphate, as is done with plants. The team then took the work further by applying techniques pioneered by Anthony Sinskey to cause the bacterium to then convert the ATP to various types of alcohols (isopentanol, isobutanol, isopropanol) which were then excreted. Nocera claimed that when the bacterium was allowed to reproduce, clusters of them were capable of producing alcohols at 6 percent efficiency and biomass at 10.6 percent efficiency, (plants in comparison are approximately 1 percent efficient at converting sunlight and carbon dioxide into biomass).Noting that some might see masses of such bacteria pulling carbon dioxide from the atmosphere as a possible solution to reducing global warming, which is believed to be at least partly caused by an excess of the gas in the atmosphere, Nocera suggested that was not the most likely outcome—he envisions people in need burning the alcohol and biomass as a fuel source, which would of course return the carbon dioxide back into the atmosphere—making it a carbon-neutral resource. He finished his lecture by announcing that he and his team are currently looking for investors to bring the technology to parts of India where it is so badly needed.

New system discovered with five planets More information: Two Small Planets Transiting HD 3167, arXiv:1607.05248 [astro-ph.EP] arxiv.org/abs/1607.05248AbstractWe report the discovery of two super-Earth-sized planets transiting the bright (V = 8.94, K = 7.07) nearby late G-dwarf HD 3167, using data collected by the K2 mission. The inner planet, HD 3167 b, has a radius of 1.6 R_e and an ultra-short orbital period of only 0.96 days. The outer planet, HD 3167 c, has a radius of 2.9 R_e and orbits its host star every 29.85 days. At a distance of just 45.8 +/- 2.2 pc, HD 3167 is one of the closest and brightest stars hosting multiple transiting planets, making HD 3167 b and c well suited for follow-up observations. The star is chromospherically inactive and slowly rotating, ideal for radial velocity observations to measure the planets’ masses. The outer planet is large enough that it likely has a thick gaseous envelope which could be studied via transmission spectroscopy. Planets transiting bright, nearby stars like HD 3167 are valuable objects to study leading up to the launch of the James Webb Space Telescope. Although Kepler has lost two of its four reaction wheels and therefore cannot be precisely pointed toward stars, it is still capable of detecting new exoworlds. The spacecraft is now in its extended mission, known as K2, during which it has already found over 100 new planets. The HD 3167 system is just the latest addition to the vast collection of extrasolar worlds detected by K2.HD 3167 was observed by Kepler between January 3 and March 23, 2016 during Campaign 8 of its K2 mission. This observation campaign allowed a team of astronomers, led by Andrew Vanderburg of the Harvard–Smithsonian Center for Astrophysics (CfA), to detect two transit signals that could be planets circling around this nearby star.”We identified two planet candidates transiting HD 3167 after processing pixel-level data to produce a light curve, removing systematic effects due to Kepler’s unstable pointing, and searching for planets using a Box Least Squares periodogram search,” the researchers wrote in the paper.To confirm the planetary status of these candidates, the team conducted follow-up observations employing the Tillinghast Reflector Echelle Spectrograph (TRES) on the 1.5 m telescope at the Fred L. Whipple Observatory on Mt. Hopkins, Arizona and the Robo-AO adaptive optics system installed at the 2.1 m telescope at the Kitt Peak National Observatory, also in Arizona. They also used statistical techniques to validate the planetary nature of the transiting signals.The confirmed exoplanets received designation HD 3167 b and HD 3167 c. With a radius of about 1.6 Earth radii, HD 3167 b is the inner planet, orbiting the host star in just slightly less than one day. The outer planet is nearly three times bigger in size than Earth and has an orbital period of approximately 30 days.HD 3167 could be an excellent target for further follow-up observations as it is one of the closest and brightest stars hosting multiple transiting planets. The scientists noted that this system is highly suitable for precise radial velocity observations to measure the planets’ masses.”If HD 3167 b is rocky with a mass of about four Earth masses, it should induce radial velocity variations with a semiamplitude of about 3 ms−1. Depending on its composition, HD 3167 c could induce radial velocity variations with a semiamplitude of anywhere between 1 ms−1 and 3 ms−1. These signals should be readily detectable with modern spectrographs,” the paper reads.The team also emphasized that the outer planet is one of the best currently known small planets for atmospheric characterization with transit transmission spectroscopy. However, they also noted that the short period of HD 3167 b makes it likely that spectroscopic observations of HD 3167 c’s atmosphere might overlap with a transit of the inner planet.”This could be an efficient way to rule out a hydrogen-dominated atmosphere for HD 3167 b. Observers should be cautious, however, to ensure that a transit of HD 3167 b not interfere with out-of-transit observations necessary for calibration,” the researchers concluded.
The Shiromani Akali Dal on Tuesday said it will contest from four seats in the February 7 Delhi assembly polls, a day after its ally, the BJP, released its list of 62 candidates.“The Shiromani Akali Dal will fight from four seats in Delhi as per the formula of our alliance with the BJP,” Akali Dal Delhi unit president Manjeet Singh GK said.Manjinder Singh Sirsa will be contesting from Rajouri Garden, Harmeet Singh Kalka from Kalkaji and Jitender Singh Shunty from Shahdara. The party left out Shyam Sharma from the Hari Nagar seat and instead chose Avtar Singh Hit. All the three candidates – Sirsa, Kalka and Shunty – had fought the 2013 polls from the same constituencies and won. Sharma, however, had lost from Hari Nagar. Of the four candidates, Sirsa will contest on the Akali Dal’s weighing scale symbol, while the other three candidates will fight on the BJP symbol.

Kolkata: State Consumer Affairs minister Sadhan Pande said that his department has initiated the process of seizure of properties of the persons who have been arrested by the police in connection with the carcass meat row.”I had written to the Kolkata Police Commissioner as well as the state Director General of Police, seeking details of the case in connection with the carcass meat issue. The Kolkata Police has forwarded details of 30 cases, while the Bidhannagar Police has sent details of eight such cases. A team of my lawyers are examining the nitty gritties and we will be initiating civil cases against them. The common people will be happy when they will see that we have been able to seize the properties belonging to the persons involved in this case,” Pande said. Also Read – Rain batters Kolkata, cripples normal lifeIt may be mentioned that some of the persons who have been arrested by the police in connection with the carcass meat row, own substantial properties including cars that they have managed to procure through the illegal business. “The criminal case will be looked after by the police and we will be starting civil cases,” Pande said.It may be mentioned that on April 20, three men were arrested in Budge Budge in South 24-Parganas, suspected of transporting carcasses from dump yards. Six days later, the police raided an ice factory in Kolkata’s Rajabazar area, recovering over 18,000 kg of rotten meat, packaged and ready to be sold. The police have arrested as many as 13 persons in connection with the case.

Kolkata: Stating that the country is experiencing a state of “super emergency”, Chief Minister Mamata Banerjee has assured that her fight of justice for the people will continue, even if lakhs of FIRs are lodged against her and her party colleagues.While reacting on the FIR lodged against her and the arrest of her party’s MPs, MLA and minister at Silchar, the Chief Minister said: “They keep lodging FIRs against us. It is interesting that I am sitting in Bengal and an FIR has been lodged in Assam…we don’t mind even if 1 lakh FIRs are lodged against us for fighting for the rights of common people.” Also Read – Rain batters Kolkata, cripples normal lifeBanerjee said that she has spoken to the Union Home minister Rajnath Singh during her visit to Delhi and the latter has assured her that there will be no harassment of common people. “My question is that then why have our MPs been harassed today?” she asked.She maintained in the same breath: “We are actually in a situation of super-emergency. There is no democracy in the country.”Condemning the arrest of her party colleagues, the Chief Minister said: “They went there for a better cause. My question is that if everything is normal and peaceful in Assam, then why has section 144 of CrPC been imposed in all the districts? Why were they (TMC MPs, MLA and minister) stopped when two of them wanted to go ahead at a time instead of marching together in a group? They just wanted to go to the convention centre and return after speaking to some people there.” “Our fight will continue for the sake of common people. We will never step back,” she added.She further added that there is no democratic right in the country. “Senior journalists are being beaten up,” she said, adding that the Army personnel from Assam, who are deployed in borders, are also worried about their family members.
Kolkata: The Trinamool Congress observed ‘black day’ in districts and blocks across the state on Saturday to protest against the “detention and manhandling” of its leaders in Assam’s Silchar airport, where they had gone to assess the situation after the publication of the final draft of the National Register of Citizens (NRC). The protest will continue on Sunday too. Carrying placards and sporting black masks and badges, TMC activists shouted slogans against the BJP governments at the Centre and Assam and the final draft of the NRC. Also Read – Rain batters Kolkata, cripples normal lifeChief Minister and TMC supremo Mamata Banerjee had alleged that the members of the delegation, including women, were manhandled at the airport and accused the BJP of imposing a “super emergency” in the country. TMC Secretary-General Partha Chatterjee had said, “What happened to our party delegation is not only shameful but also undemocratic. Our slogan will be ‘we don’t need this monstrous government any more’.”At Englishbazar, Malda, BJP workers attacked Trinamool Congress supporters who were participating in a rally. The BJP workers demanded that the NRC should start in Bengal, too, and that those whose names would be in the list should be deported to Bangladesh. A large police contingent went to the spot and brought the situation under control. Krishnendu Narayan Chowdhury said that the BJP was trying to create chaos in different parts in the district. “Trinamool Congress supporters had taken part in a rally and the BJP workers attacked them without any provocation.”In Kolkata, an effigy of PM Narendra Modi was burnt by TMC supporters at a rally led by minister Subrata Mukherjee. “Those whose names have been dropped from NRC are panicking and really do not know what to do. The BJP is ruining the country with its divisive politics,” said Mukherjee.
Even if your five-year-old kid does not know what money can buy for him or her, the moment he or she gets to know the value of it, chances are the knowledge may make him or her less philanthropic in nature, says an interesting research.In other words, the act of handling money makes young children work harder and give less. This effect was observed in children who lacked the concrete knowledge of money’s purpose and persisted despite the denomination of the money. Also Read – ‘Playing Jojo was emotionally exhausting’“Money is a double-edged sword. It produces good outcomes in terms of concentration and effort but bad outcomes when it comes to helping, taking, and donating.” said professor Kathleen Vohs from the University of Minnesota and co-author of the study.For this, the researchers conducted five experiments and one study involving 550 children (ages three-six) in Poland and the US. In one experiment, the children were asked to either sort money or buttons before completing a challenging puzzle. The paper is forthcoming in the journal Psychological Science.

Her design label ‘Cobia’ has a unique collection of evening and informal dresses in rich and vibrant colours each dress unique in itself.
Good oral hygiene can reduce bad bacteria in the mouth and thus decrease the risk of developing pneumonia, a research has found. Pneumonia is an infection that inflames air sacs in one or both lungs, which may fill with fluid.The infection is more common among older people and those with conditions such as AIDS or lung disease. The study found that people who never get dental checkups had an 86 per cent greater risk of pneumonia than those who visit the dentist twice a year. Also Read – Add new books to your shelf“There is a well-documented connection between oral health and pneumonia, and dental visits are important in maintaining good oral health,” said lead author Michelle Doll, Assistant Professor at Virginia Commonwealth University in the US.“We can never rid the mouth of bacteria altogether, but good oral hygiene can limit the quantities of bacteria present,” Doll added.The human body contains 10 times as many microbes (bacteria, fungi and viruses) as human cells on or in the body, from the skin to the gastrointestinal system (including the mouth). Some microbes are good and some are bad, but even bad microbes only cause disease under certain circumstances. In some cases, bacteria can be accidentally inhaled or aspirated into the lungs and cause pneumonia. Bacteria that commonly cause pneumonia include streptococcus, haemophilus, staphylococcus, and anaerobic bacteria. Routine dental visits may reduce the amount of bacteria that can be aspirated, Doll said. “Our study provides further evidence that oral health is linked to overall health, and suggests that it’s important to incorporate dental care into routine preventive healthcare,” Doll said.
Lingerie is the most important foundation piece for putting together a great outfit you feel comfortable in and look the best in silhouette. It is important to choose the right bra that not only compliments your body shape but also offers high comfort and best fit. Invest time in having a professional bra fit because the size and shape of your breasts impact your choice of bra shape and size for your perfect fit. You know when you have the right bra fit, when it’s so comfortable you hardly know you are wearing one.Make sure to try on different bras to understand which shape makes you feel most comfortable. Your bra should be a snug fit but never dig into your sides. Also ensure the underwire doesn’t dig into your chest or pinch your skin, if this happens then try a bigger cup size.Your bra straps shouldn’t be too loose or tight and be adjustable to your desired level of elevation.The cups should be smooth and the edges should lay flat against your chest when you have the correct fit, without any bulges over the cup. The best way to ascertain you have the right cup size is to lift your arms and the bra should stay perfectly in place.The biggest mistake most women make is not wearing the right cup size. Band sizes are measured in even numbers, when you have fastened the underband you should only be able to pull the bra 4-5 cms away at the back, to get the best support. Cups should fully encase your breast without spillage.As a practice, get yourself measured every six to twelve months as your size can regularly change due to both weight loss and gain. It is imperative to get yourself fitted by a fully trained bra-fit expert at regular intervals to make sure that you have the right size.If your breasts rest too close to each other then you need to find a bra with moulded cups with high centre gore. This will allow your breasts to settle in respective cups and give a fuller look.If your breasts rest wide apart then you need a bra with sturdy side wings and side boning to support breast tissues and move them into the cups. Go for a push up bra.If you have firm and full breasts then a full coverage bra is a good choice. It gives full support to breast tissues.If you have shallow breasts then demi cup bra with wide straps or a push up bra will suit you the best. It will give that needed push to your breasts and give them a rounded appearance as well. Women with broad shoulders, should go for a balconette bra with wide set straps for steady hold.

Kolkata: Former CPI(M) MP Jyotirmoyee Sikdar joined Trinamool Congress on Thursday. Sikdar, an athlete and Rajiv Gandhi Khel Ratna awardee in 1998-99, was elected from the Krishnanagar Lok Sabha seat in 2004. She was defeated by Trinamool Congress candidate Tapas Paul in 2009.Sikdar was a close aide of former Sports minister Subhas Chakraborty. She had taken part in CPI(M)’s campaign in the 2016 Assembly election. After joining Trinamool Congress along with 200 CPI(M) supporters, the former MP said she was attracted by the all-round development carried out in Bengal by Chief Minister Mamata Banerjee.
It is natural for parents to protect their children from any harm, including the endless array of germs they are exposed to every day.As children grow up, they are continuously exposed to various germs, especially in places such as daycare centres and preschool. Children with low immunity are highly susceptible to various types of infections. The high incidence of infections has led to an increased and inappropriate use of antibiotics, which has further resulted in antimicrobial resistance. Also Read – Add new books to your shelfAntimicrobial resistance, a widespread problem, takes places when microbes build resistance against the medications intended to kill them due to overuse. It is one ofthe world’s most pressing public health problems. The best way to tackle this is to build a strong immunity, which naturally protects your child from infections. Experts share a few tips that can help boost your child’s immunity.Healthy DietA healthy diet that comprises all fundamental components like proteins, minerals, vitamins, micronutrients and unsaturated fats in optimum quantity, helps build the immunity required to fight against various infections or diseases in children. Citrus fruits, carrots, green leafy vegetables, beans, strawberry, yogurt, garlic, and ginger help build immunity with their immunity-boosting properties. Also Read – Over 2 hours screen time daily will make your kids impulsiveAdequate SleepSleep deprivation suppresses the functionality of the immune system, which makes children susceptible to infections. Adequate sleep is an absolute necessity to rejuvenate the body. Newborns need up to 18 hours of sleep a day, toddlers require 12 to 13 hours, and preschoolers need about 10 hours of sleep.Hygiene Maintaining hand hygiene before and after each meal, after playtime, handling pets, blowing the nose, using the restroom and arriving home from daycare helps prevent infections in children. Herbal SolutionsDespite taking proper care, children’s immunity may be affected. Consumption of herbal dietary supplements like Guduchi (Tinospora cordifolia), Amalaki (Emblica officinalis), Yashtimadhu (Glycyrrhiza glabra), and Guggulu (Balsamodendron mukul) can help children stay healthier as they help build immunity.”Naturally obtained supplements strengthen the immune system. Herbs like Guduchi, Yashti Madhu, and Guggulu are natural sources of antioxidants. The antiviralproperty of Yashtimadhu also helps manage asthma, bronchitis, and chronic cough. The anti-inflammatory property of Guggulu helps reduce inflammation,” experts said.A combination of herbs may be a safe and effective adjuvant to antimicrobials in the management of recurrent infections. When co-prescribed with antibiotics, herbs mayhelp in faster recovery, reduces duration and cost of therapy, preventing reinfections.
