UT RESEARCHERS DEVELOP ®EVOLUTIONARY CIRCUITS

Researchers of the MESA+ Institute for Nanotechnology and the CTIT Institute for ICT Research at the University of Twente in The Netherlands have demonstrated working electronic circuits that have been produced in a radically new way, using methods that resemble Darwinian evolution. The size of these circuits is comparable to the size of their conventional counterparts, but they are much closer to natural networks like the human brain. The findings promise a new generation of powerful, energy-efficient electronics, and have been published in the leading British journal Nature Nanotechnology.

One of the greatest successes of the 20th century has been the development of digital computers. During the last decades these computers have become more and more powerful by integrating ever smaller components on silicon chips. However, it is becoming increasingly hard and extremely expensive to continue this miniaturisation. Current transistors consist of only a handful of atoms. It is a major challenge to produce chips in which the millions of transistors have the same characteristics, and thus to make the chips operate properly. Another drawback is that their energy consumption is reaching unacceptable levels. It is obvious that one has to look for alternative directions, and it is interesting to see what we can learn from nature. Natural evolution has led to powerful ‘computers’ like the human brain, which can solve complex problems in an energy-efficient way. Nature exploits complex networks that can execute many tasks in parallel.

Transport Quantum bits via superconducting nanowires. Definite step forward in information transmittal capabilities.

Although 74 picoseconds may not sound like much — a picosecond is a trillionth of a second — it is a big deal in the quantum world, where light particles, or photons, can carry valuable information. In this case it means that much less “jitter,” or uncertainty in the arrival time of a photon. Less jitter means that photons can be spaced more closely together but still be correctly detected. This enables communications at a higher bit rate, with more information transmitted in the same period.

Every little bit helps when trying to receive faint signals reliably. It helped, for example, in NIST’s recent quantum teleportation record and difficult tests of physics theories. In such experiments, researchers want to decode as much information as possible from the quantum properties of billions of photons, or determine if “entangled” photons have properties that are linked before — or only after — being measured.

NIST has made many advances in photon detector designs. In the latest work, described in Optics Express, NIST researchers used an electron beam to pattern nanowires into a thin film made of a heat-tolerant ceramic superconductor, molybdenum silicide. The tiny boost in energy that occurs when a single photon hits is enough to make the nanowires briefly lose their superconducting capability and become normal conductors, signaling the event.

First, this study is very biased and flawed. Secondly, have the tech companies considered all of the resistance that we’re all going to face with the provider and payer communities plus their lobbyists when we try to promote medical AI, nanobots, etc.

I have seen some resistance mounted by some providers, some pharma, etc. against CRISPR. And, I believe this type of resistance is only going to hurt patients as well as many cancer survivors with a genetic predisposition to cancer, and other genetic mutations.

A study of mobile health apps’ impact on health care costs represents a limited but crucial step for assessing digital medicine.

This is not good especially as we look at those aspirations for more nanobots to connect us to the cloud plus Mr. Kurzweil’s desire to live forever.

Medical device manufacturers are struggling to safeguard their newly connected designs from current and emerging security threats.

Natick, MA (PRWEB) January 29, 2016.

The medical device sector will be among the fastest growing markets for embedded security software through the next five years, according to a new report by VDC Research (click here to learn more). The market for medical devices spans a variety of hardware profiles including high-performance imaging systems, mobile diagnostic equipment and pumps, and wearable or implantable devices. Until recently, the majority of medical device manufacturers and others within the ecosystem treated security as an optional value-add under the misconception that their devices/products did not produce valuable data or would be a target for a hacker. The Internet of Things has enlarged the crosshairs on medical devices as such systems become more accessible and integrated with enterprise hospital platforms.

The burgeoning field of nanotechnology promises an indefinite range of capabilities in medicine, optics, communications, and other facets of applied science and engineering. On that front, the U.S. Defense Advanced Research Projects Agency’s (DARPA) Atoms 2 Products program (A2P) is funding 10 companies, universities, and institutions to develop mass-manufacturing techniques and technologies for functional products made up of nanoscale constituents. The project demonstrates a mere slice of the contributions in the mass movement to make nanotechnology a part of our everyday lives.

The following gallery highlights the work of five DARPA-funded projects in the program. The slides describe an atomic calligraphy technique for 2D atomic printing, a manufacturing method for producing high-frequency “Nanolitz” wires, the construction of pop-up sensors for laparoscopy, and a conjunct effort to use micro-robotics to build the assemblers of nanodevices.

With a growing number of Earth-like exoplanets discovered in recent years, it is becoming increasingly frustrating that we can’t visit them. After all, our knowledge of the planets in our own solar system would be pretty limited if it weren’t for the space probes we’d sent to explore them.

The problem is that even the nearest stars are a very long way away, and enormous engineering efforts will be required to reach them on timescales that are relevant to us. But with research in areas such as nuclear fusion and nanotechnology advancing rapidly, we may not be as far away from constructing small, fast interstellar space probes as we think.

There’s a lot at stake. If we ever found evidence suggesting that life might exist on a planet orbiting a nearby star, we would most likely need to go there to get definitive proof and learn more about its underlying biochemistry and evolutionary history. This would require transporting sophisticated scientific instruments across interstellar space.

The legal death of Marvin Minsky was publicly reported on Monday, January 25, 2016. There has been speculation on the part of numerous individuals and publications that he may have been cryopreserved by Alcor. This notice is Alcor’s formal response to inquiries on this issue.

In a public ceremony at the Extro-3 conference in 1997, nanotechnology pioneer Eric Drexler presented Prof. Minsky with a bracelet given to all new Alcor members. This bracelet provides emergency contact information and basic instructions. Minsky has spoken publicy many times about his advocacy of overcoming aging and the inevitability of death and about cryonics (human cryopreservation) as a last resort. He was also among the 67 signatories of the Scientists Open Letter on Cryonics and a member of Alcor’s Scientific Advisory Board. This much is public knowledge. None of this necessarily means that Prof. Minsky had cryopreservation arrangements at the time of legal death. Alcor neither confirms nor denies whether Prof. Minsky had such arrangements.

Alcor’s official response may puzzle some readers, so we would like to point out the privacy options that have been and currently are available to our members. When a member signs up for cryopreservation by Alcor, they have four options:

Luv the whole beautiful picture of a Big Data Quantum Computing Cloud. And, we’re definitely going to need it for all of our data demands and performance demands when you layer in the future of AI (including robotics), wearables, our ongoing convergence to singularity with nanobots and other BMI technologies. Why we could easily exceed $4.6 bil by 2021.

From gene mapping to space exploration, humanity continues to generate ever-larger sets of data—far more information than people can actually process, manage, or understand.

Machine learning systems can help researchers deal with this ever-growing flood of information. Some of the most powerful of these analytical tools are based on a strange branch of geometry called topology, which deals with properties that stay the same even when something is bent and stretched every which way.

Such topological systems are especially useful for analyzing the connections in complex networks, such as the internal wiring of the brain, the U.S. power grid, or the global interconnections of the Internet. But even with the most powerful modern supercomputers, such problems remain daunting and impractical to solve. Now, a new approach that would use quantum computers to streamline these problems has been developed by researchers at MIT, the University of Waterloo, and the University of Southern California…

Researchers at the University of Colorado have created a unique, light-activated nanotherapy to destroy antibiotic resistant bacteria

The pursuit of longevity requires continued, effective antibiotics. Otherwise, you could be as fit as a fiddle at 100 and still be downed by a nasty, resistant strain.

While bacterial strains resistant to current drugs are rapidly rising across the globe, infecting 2 million people last year, researchers are turning to increasingly innovative ways to destroy these populations. Nanotechnology is one such, increasingly promising technology.
