Blockchain, cryptocurrencies, and central banks: Opportunity or threat? — By Dirk Niepelt | World Economic Forum
Posted by Odette Bohr Dienel in category: cryptocurrencies
“Central banks increasingly are under pressure to keep ‘their’ currencies attractive. They should let the general public access electronic central bank money, not just financial institutions ( Niepelt 2015). To do this, they should embrace the blockchain.”

Edmonton researchers’ tiny discovery may revolutionize computers
Posted by Karen Hurst in categories: computing, nanotechnology, particle physics, quantum physics
New method for creating smaller switches for QC identified and making smaller and more efficient QC systems possible.
Edmonton nanotechnology researchers working with atom-sized materials have made a breakthrough that could lead to smaller, ultraefficient computers.
The team, led by Robert Wolkow, together with collaborators at the Max Planck Institute in Hamburg, have developed a way to create atomic switches for electricity nearly 100 times smaller than the smallest switches, or transistors, on the market today. Their findings appeared in the Oct. 26 edition of the scientific publication Nature Communications.

Tiny Computer Pushes the Envelope with Micro-Memory
Posted by Karen Hurst in category: computing
Talk about downsizing – researchers at the University of California in Santa Barbara have developed a design for a 50 nanometer square computer, the university announced Oct. 27.
For now, that size is entirely theoretical. It could be managed by a novel kind of logic that enables the computer to process data inside a three-dimensional structure.
“In a regular computer, data processing and memory storage are separated, which slows down computation. Processing data directly inside a three-dimensional memory structure would allow more data to be stored and processed much faster,” said Gina Adam, a postdoctoral researcher and the lead author of the paper.

How Nanoscience Will Improve Our Lives in the Coming Years
Posted by Karen Hurst in categories: biotech/medical, food, health, nanotechnology
In a newly published study, nanoscientists look ahead to what we can expect in the coming decade, and conclude that nanoscience is poised to make important contributions in many areas, including health care, electronics, energy, food and water.
Nanoscience research involves molecules that are only 1/100th the size of cancer cells and that have the potential to profoundly improve the quality of our health and our lives. Now nine prominent nanoscientists look ahead to what we can expect in the coming decade, and conclude that nanoscience is poised to make important contributions in many areas, including health care, electronics, energy, food and water.
Significant progress has already been made in nanomaterials, report authors Paul Weiss, who holds a UC presidential chair and is a distinguished professor of chemistry and biochemistry at UCLA, and Dr. Andre Nel, chief of nanomedicine at the David Geffen School of Medicine at UCLA. In the journal ACS Nano, Weiss, Nel, who is a distinguished professor of medicine, and their colleagues say the following:

New Technique Reveals Powerful, “Patchy” Approach to Nanoparticle Synthesis
Posted by Karen Hurst in categories: nanotechnology, particle physics, solar power, sustainability
Patches of chain-like molecules placed across nanoscale particles can radically transform the optical, electronic, and magnetic properties of particle-based materials. Understanding why depends critically on the three-dimensional features of these “polymer nano-patches”—which are tantalizingly difficult to reveal at a scale spanning just billionths of a meter.
Now, scientists have used cutting-edge electron tomography techniques—a process of 3D reconstructive imaging —to pinpoint the structure and composition of the polymer nano-patches. The results, published earlier this month in the journal Nature, “lay the foundation for new nanoscale architectures that could potentially enhance technologies such as self-assembled solar cells and catalysts,” said lead author Eugenia Kumacheva of the University of Toronto.

Researchers nearly reach quantum limit with nanodrums
Posted by Karen Hurst in categories: encryption, quantum physics
Extremely accurate measurements of microwave signals can potentially be used for data encryption based on quantum cryptography and other purposes.
Researchers at Aalto University and the University of Jyväskylä have developed a new method of measuring microwave signals extremely accurately. This method can be used for processing quantum information, for example, by efficiently transforming signals from microwave circuits to the optical regime.
