What Do Single Neurons Know

Posted by in categories: computing, neuroscience

But, the larger question remains as to how these individual dendrites and neuron outputs are used by the circuit and the brain as a whole. These findings are considerably different than sequences needing a group of neurons working in order and in a circuit. Even more unusual is the fact that (even young childrens’) brains are able to analyze and respond to information that is, in fact, so complex that the most advanced super computers cannot. Can individual cells do this as well?

Another new set of research shows that in a monkey brain, these responses of individual neurons are correlated somewhat with the final decision of the animal. This research used very limited visual information and showed that the final decisions of the animal using billions of neurons was perhaps relevant even to this small amount of information input given to individual cells.

It could be that the local neuron responded to the decision that was made by the larger circuits and brain. But, it doesn’t answer the question as to how the individual neuron relates to the brain.

Seeing the quantum future… literally

Posted by in categories: computing, quantum physics

Scientists at the University of Sydney have demonstrated the ability to “see” the future of quantum systems, and used that knowledge to preempt their demise, in a major achievement that could help bring the strange and powerful world of quantum technology closer to reality.

The applications of quantum-enabled technologies are compelling and already demonstrating significant impacts — especially in the realm of sensing and metrology. And the potential to build exceptionally powerful quantum computers using quantum bits, or qubits, is driving investment from the world’s largest companies.

However a significant obstacle to building reliable quantum technologies has been the randomisation of by their environments, or decoherence, which effectively destroys the useful quantum character.

Next-Gen Computing Game Changers: Quantum Computers And Beyond

Posted by in categories: computing, quantum physics

Although this was published last week; I got a request to share again for those who missed it.


While “product-market fit” may have become the mantra for many tech companies and investors, we believe there are still plenty of companies out there with their eyes set on building true game-changing technologies. In our Game Changers report, we identified 8 categories of innovation that could have the greatest impact on how we live. Among these is next-gen computing — specifically, quantum computers and DNA data-writing technologies, which have the potential to fast-track innovation across industries.

Quantum computers can solve real-world problems much faster than traditional computers — and their capacity is only increasing. Meanwhile, using synthetic DNA to store vastly more data than a typical chip has the potential to revolutionize computers’ memory capacity.

New Cooling Technique Could Aid Development Of Quantum Computers

Posted by in categories: computing, particle physics, quantum physics

Nice.


A sophisticated cooling technique — using lasers to cool individual atoms — was demonstrated at the National Institute of Standards in Technology in 1978, and is now used in a wide array of precise applications, such as atomic clocks. Using the same principle, NIST physicists have now “cooled a mechanical object to a temperature lower than previously thought possible,” passing the so-called “quantum limit” which imposes limits on accuracy for quantum scale measurements.

Described in a paper titled “Sideband cooling beyond the quantum backaction limit with squeezed light,” published Thursday in the journal Nature, the technique could theoretically be used to cool objects to absolute zero, when matter exhibits almost no energy or motion.

Semiconductor nanopyramids for building high-yield quantum photonic devices

Posted by in categories: computing, particle physics, quantum physics

Novel structures exhibit highly directional emission and provide a template for site-controlled quantum dots and self-aligned nanophotonic cavities.

Semiconductor quantum dots (QDs) are thought to be a promising candidate for a single-quantum emitter in on-chip systems because of their well-developed growth and fabrication techniques. Semiconductor QDs, however, have a number of inherent limitations that need to be overcome before they can be used in practical applications. For example, QDs in semiconductors are strongly affected by elements (e.g., phonons) in the surrounding environment, which results in short nonradiative decay times and rapid dephasing processes. Despite the high intrinsic radiative decay rates of semiconductor QDs compared with those of other single-quantum emitters (such as atoms and ions), the radiative decay rate needs to be further increased so that these fast nonradiative and dephasing processes can be overcome. Furthermore, the collection efficiency of the light that is emitted from conventional QDs embedded in a high-index planar substrate is typically low (about 4%).

Addressing Naturalistic Objections to Extending Healthy Human Life Spans

Posted by in categories: biotech/medical, computing, life extension, neuroscience

Playing God is a common objection to developing technologies to increase human lifespan and yet it is never used in relation to current therapies already available.


Here I’ll point out another of the articles going up at the Life Extension Advocacy Foundation, this time on the topic of the naturalistic fallacy where it occurs in opposition to healthy life extension. Our community would like to build medical therapies that address the causes of aging, thereby ending age-related disease and greatly extending healthy human life spans. It has always surprised me to find that most people, at least initially, object to this goal. It seems perfectly and straightforwardly obvious to me that aging to death, suffering considerably along the way, is just as much a problem to be overcome as any other medical condition that causes pain and mortality. Yet opposition exists, and that opposition is one of the greatest challenges faced when raising funding and pushing forward with research and development of rejuvenation therapies.

When it comes to treating aging as a medical condition the naturalistic fallacy is voiced in this way: aging is natural, what is natural is good, and therefore we shouldn’t tamper with aging. If you look around at your houses, your computers, your modern medicine, and consider that such an objection is perhaps just a little late to the game, and hard to hold in a self-consistent manner, then you’re probably not alone. Notably, the same objection is rarely brought up when it comes to treating specific age-related diseases, or in the matter of therapies that already exist. People who are uncomfortable about radical changes to the course of aging and who speak out against the extension of human life are nonetheless almost all in favor of cancer research, treatments for heart disease, and an end to Alzheimer’s disease. Yet age-related diseases and aging are the same thing, the same forms of damage and dysfunction, only differing by degree and by the names they are given.

A World-Renowned Futurist Reveals The Hotel Of The Future

Posted by in categories: biotech/medical, computing, virtual reality

His vision is definitely achievable.


The future of airport transfer—in a pod.

World-renowned global futurist Dr. James Canton envisions hotel experiences that include supersonic travel and DNA-driven spa treatments, so what can we expect in the next decade? Canton, a former Apple Computer executive, author and social scientist, worked in conjunction with Hotels.com, to present the Hotels of the Future Study at a recent conference in San Francisco. In the study he describes hotels with everything from RoboButlers and virtual reality entertainment to hotel restaurants based on gourmet genomics and the emergence of neurotechnology to make sleep more refreshing. Canton, who has advised three White House Administrations and over 100 companies, believes these megatrends will shape the future of the hotel experience and that the RoboButler is the change we will most likely see first. Although, he also notes that plans are already underway for a supersonic hyperloop route from Los Angeles to New York City.
