Passive Liquid Flow Can Aid Nanotechnology Development, Study Suggests

Posted by in categories: computing, engineering, nanotechnology, particle physics

Again organic nature teaches technology.


A new study, inspired by water’s movement from roots to leaves in tall trees, shows that a certain kind of passive liquid flow, where liquids naturally move in response to surface atomic interactions instead of being driven by external forces like pumps, is remarkably strong. By virtually modeling the way atoms interact at a solid surface, College of Engineering and Computer Science researchers suggest that passive liquid flow could serve as a highly efficient coolant-delivery mechanism without the need for pumps. The results, published in Langmuir, also have implications for the development of new nanoscale technology.

Diamond microdisk “with huge potential” for quantum computing

Posted by in categories: computing, nanotechnology, quantum physics

The diamond microdisk made by Paul Barclay and his team of physicists could lead to huge advances in computing, telecommunications, and other fields.

Barclay and his research group — part of the University of Calgary’s Institute for Quantum Science and Technology and the National Institute of Nanotechnology — have made the first-ever nano-sized optical resonator (or optical cavity) from a single crystal of diamond that is also a mechanical resonator.

The team also measured — in the coupling of light and mechanical motion in the device — the high-frequency, long-lasting mechanical vibrations caused by the energy of light trapped and bouncing inside the diamond microdisk optical cavity.

Microsoft is reprogramming cancer

Posted by in categories: biotech/medical, computing

Microsoft is thinking about cancer in terms of computer software.

Microsoft wants to “solve” cancer, and is doing it by thinking about the body like a computer.

The technology giant may be more closely associated with malware than malignant diseases, but researchers working for the company’s “biological computation” unit in Cambridge are showing the former isn’t entirely separate from the latter.

In vivo work with neural dust using a wireless and scalable ultrasonic backscatter system for powering and communicating the implanted bioelectronics

Posted by in categories: bioengineering, biotech/medical, computing, neuroscience

Berkeley engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time.

Neural dust researchers have already shrunk them to a 1 millimeter cube – about the size of a large grain of sand – contain a piezoelectric crystal that converts ultrasound vibrations from outside the body into electricity to power a tiny, on-board transistor that is in contact with a nerve or muscle fiber. A voltage spike in the fiber alters the circuit and the vibration of the crystal, which changes the echo detected by the ultrasound receiver, typically the same device that generates the vibrations. The slight change, called backscatter, allows them to determine the voltage.

How quantum computing could unpick encryption to reveal decades of online secrets

Posted by in categories: computing, encryption, quantum physics, security

QC will need to be on any IT, Security, and/ or tech connected product future state roadmap that spans a 5 + year period because the planning, funding, change management (retooling of resources), etc. will take time to plan & prepare not to mention all those internal & external dependencies and their own efforts around QC in the future because it truly would stink to see an AT&T, or HomeDepot, etc. that invested in their own QC compliant infrastructure suddenly attacked because an external source that they pull from is not QC.


The encryption we take for granted as being uncrackable would have a limited shelf-life in the quantum age, says a security expert.

Prepare for threat of quantum computing to encrypted data, Canadian conference told

Posted by in categories: business, computing, encryption, government, quantum physics, security

My suggestion; don’t be one of those companies and governments in the next 5yrs that waits until the 9th hour meanwhile others planned, invested, and executed properly so they’re not exposed like you are.


The race to create new cryptographic standards before super-fast quantum computers are built that can rip apart data protected by existing encryption methods isn’t going fast enough, two senior Canadian officials have warned a security conference.

“I think we are already behind,” Scott Jones, deputy chief of IT security at the Communications Security Establishment (CSE), responsible for securing federal information systems, told the fourth annual international workshop on quantum-safe cryptography in Toronto on Monday.

Quantum chip keeps you guessing

Posted by in categories: computing, economics, finance, nanotechnology, quantum physics

Random numbers have become important in daily life, given how they are at the heart of e-commerce and secure communications and also form the basis of statistical methods of solving problems in engineering and economics. And yet, truly random numbers are difficult to generate. A series of seemingly random numbers can still show patterns, and this can lead to frauds in e-commerce or errors in computations. Carlos Abellani, Waldimar Amaya, David Domenech, Pascual Munoz, Jose Capmany, Stefano Longhi, Morgan W Michell and Valerio Pruneri from the Institutes of Science and Technology and the Institute of Research and Advanced Studies at Barcelona, Polytechnic University and the firm, VLC Photonica, at Valencia and the Institute of Photonics and Nanotechnology at Milan, describe in the Optical Society’s journal, Optica, a method of using quantum effects to generate truly random numbers with the help of a miniature device that can be embedded in a mobile phone. The operative quality of random numbers is that those in a series cannot be predicted from the preceding ones, nor even any of the digits that appear in them.

Once a random number has been exchanged by a pair of correspondents, they can base a code on this number and keep their exchanges confidential. Devices like computers, which handle e-commerce transactions, thus routinely generate hundreds of large random numbers. The numbers generated by a complex formula are based on a “seed” number to get started, and do pass many statistical tests of randomness. The numbers, however, are not truly random and if a third party should guess the “seed” that was used, he/she could work out the numbers and impersonate others in transactions. Real random numbers are created not by a formula but by physical processes, like the last digits of the number of grains in a handful of sand, the throw of honest dice or even the last digit of the daily stock market index.

Alarms Raised Over DARPA-Funded ‘Neural Dust’

Posted by in categories: biotech/medical, computing, internet, neuroscience

Alarms are being raised over the recent advancements in a new DARPA-funded technology known as “electroceuticals,” with the possibility that dark forces could be unleashed in a world where millions have hundreds of tiny neural dust sensors gathering and transmitting the most personal of information into external computer networks. The fears being that non-state actors, hostile nations, and could hack into the most secure and sensitive databases, gaining access to in-body telemetry from a head of state or sending nefarious commands directly into their brain unleashing havoc.

Engineers at UC Berkeley have cracked the millimetre barrier producing the first dust-sized wireless sensor small enough to implant into the body and be parked next to a muscle, nerve or organ. These motes are sprinkled thoughout the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time. The neural dust sensor is born from a DARPA funded weapons program. (DARPA is also the organization responsible for creating the Internet).

We already have zero ability to keep foreign actors, hostile groups, not to mention cybercriminals, from hacking into the most secure and sensitive databases. If they gained access to in-body telemetry from a head of state or sent nefarious commands directly into their brain, what havoc they could wreak.

Microsoft wants to crack the cancer code using artificial intelligence

Posted by in categories: biotech/medical, computing, health, robotics/AI

Cancer is like a computer virus and can be ‘solved’ by cracking the code, according to Microsoft. The computer software company says its researchers are using artificial intelligence in a new healthcare initiative to target cancerous cells and eliminate the disease.

One of the projects within this new healthcare enterprise involves utilizing machine learning and natural language processing to help lead researchers sift through all the research data available and come up with a treatment plan for individual cancer patients.

IBM is working on something similar using a program called Watson Oncology, which analyzes patient health info against research data.
