Using Adenosine Triphosphate to Create Biological Super-Computers

Machines running on human energy? Yes, it can happen, according to Dan Nicolau, Jr. from the Department of Integrative Biology at the University of California. Nicolau and his colleagues successfully completed a proof-of-concept study of a book-sized computer that runs on adenosine triphosphate (ATP), a biochemical that releases energy in cells and aids in energy transfer.

The study results published in the Proceedings of the National Academy of Sciences (PNAS), describe the combination of geometrical modeling and engineering as well as nanotechnology to create circuitry that uses 1.5 × 1.5 cm in area and the naturally occurring protein to operate.

A More Sustainable Option

Other than the mere presence of a human energy source in a machine, an astounding aspect of the device is how, as opposed to electrical energy that produces heat, the biological agent powering this new computer enables it to remain cool and energy efficient, making it more sustainable.

Analogue quantum computation has been universally digitized using superconducting circuits

The QUTIS research group (www.qutisgroup.com) of the University of the Basque Country (UPV/EHU) and Google’s quantum computation team have collaborated on a pioneering experiment that universally digitizes analogue quantum computation on a superconducting chip. This breakthrough was made at Google’s labs in Santa Barbara (California) and has been published in the prestigious journal Nature.

World-first pinpointing of atoms at work for quantum computers

Nice!

Scientists can now identify the exact location of a single atom in a silicon crystal, a discovery that is key for greater accuracy in tomorrow’s silicon based quantum computers.

It’s now possible to track and see individual phosphorus atoms in a silicon crystal allowing confirmation of quantum computing capability, but which also has use in nano detection devices.

Quantum computing has the potential for enormous processing power in the future. Current laptops have transistors that use a binary code, an on-or-off state (bits). But tomorrow’s quantum computers will use quantum bits ‘qubits’, which have multiple states.

US intelligence unit to advance management of virtual desktop security, systems

Getting a handle on cloud-based virtual operations is no easy task. Next month researchers from the Intelligence Advance Research Projects Activity (IARPA) will introduce a new program that looks to address that management concern by developing better technology to manage and secure Virtual Desktop Infrastructure (VDI) environments.

IARPA, the radical research arm of the of the Office of the Director of National Intelligence will introduce the Virtuous User Environment (VirtUE) which it says aims to “creatively define and develop user environments that are more dynamic, secure, auditable, transferrable, and efficient than the current offerings provided by traditional physical workstations and commercial VDI; develop innovative, dynamic analytics and infrastructures that can leverage these newly developed user environments to both automatically detect and deter security threats that IC user environments will be subject to in the new cloud infrastructure.”

Future humans: Immortal, jobless and genius

What will we do when money has no meaning? And if everyone gets life extension what will today’s mega rich think and/or do about it?

May you live in interesting times – A curse, origin unknown

One of the ‘curses’ usually attributed to ancient China, but frequently thrown around in today’s society is ‘May you live in interesting times’, suggesting that living in turbulent times, no matter the cause, is somehow a bad thing.

True or not, there is no denying one thing – every individual fragment of time was interesting in its own right, and I’ll be free to say that life has never been as interesting as it is today. Just look at what humans did in the last 40 years – first we got computers, then the internet, mobile phones, smartphones, high-speed internet, high-speed internet on smartphones, social media, virtual reality, augmented reality, drones, exoskeletons, prosthetic mind-controlled limbs… all of these things happened in less than a single lifetime.

Pairing nanodiamonds with other nanomaterials could enable huge advances in nanotechnology

Very promising. I imagine 3D Printers being able to create synthesize diamonds will be a very profitable business to get in to because of the stabilizing benefits that the nanodiamonds bring to Quantum Computing and nanotechnology in general.

Nanomaterials have the potential to improve many next-generation technologies. They promise to speed up computer chips, increase the resolution of medical imaging devices and make electronics more energy efficient. But imbuing nanomaterials with the right properties can be time consuming and costly. A new, quick and inexpensive method for constructing diamond-based hybrid nanomaterials could soon launch the field forward.

University of Maryland researchers developed a method to build diamond-based hybrid nanoparticles in large quantities from the ground up, thereby circumventing many of the problems with current methods. The technique is described in the June 8, 2016 issue of the journal Nature Communications (“Nanostructures for Coupling Nitrogen-Vacancy Centers to Metal Nanoparticles and Semiconductor Quantum Dots”).
