I cannot wait. However, wish they would look at cancer treatment as one of the first trials.

Yep; devices and computers will no longer be needed given the advancements that are coming in areas of Quantum, Synbio, nanotech, etc.
However, with QC crystal technology and the work done on parallel states we have some very interesting things coming in communications, entertainment/ media, etc.
The long read: For decades, computers have got smaller and more powerful, enabling huge scientific progress. But this can’t go on for ever. What happens when they stop shrinking?

Could we eventually see a day where we have cell circuitry nanobot pill that eliminates hunger and obesity as replacement to gastric bypasses? Maybe.
The human body responds to starving conditions, such as famine, to promote the chance of survival. It reduces energy expenditure by stopping heat production and promotes feeding behavior. These “hunger responses” are activated by the feeling of hunger in the stomach and are controlled by neuropeptide Y (NPY) signals released by neurons in the hypothalamus. However, how NPY signaling in the hypothalamus elicits the hunger responses has remained unknown.
Sympathetic motor neurons in the medulla oblongata are responsible for heat production by brown adipose tissue (BAT). Researchers centered at Nagoya University have now tested whether the heat-producing neurons respond to the same hypothalamic NPY signals that control hunger responses. They injected NPY into the hypothalamus of rats and tested the effect on heat production. Under normal conditions, blocking inhibitory GABAergic receptors or stimulating excitatory glutamatergic receptors in the sympathetic motor neurons induced heat production in BAT. After NPY injection, stimulating glutamatergic receptors did not produce heat, but inhibiting GABAergic receptors did. The study was recently reported in Cell Metabolism.
Today scientists at the Institute for Research in Biomedicine (IRB Barcelona) present a study in Cell (“The in vivo architecture of the exocyst provides structural basis for exocytosis”) where they have been able to observe protein nanomachines (also called protein complexes)—the structures responsible for performing cell functions—for the first time in living cells and in 3D. This work has been done in collaboration with researchers at the University of Geneva in Switzerland and the Centro Andaluz de Biología del Desarrollo in Seville.

Advanced photonic nanostructures are well on their way to revolutionising quantum technology for quantum networks based on light. Researchers from the Niels Bohr Institute have now developed the first building blocks needed to construct complex quantum photonic circuits for quantum networks. This rapid development in quantum networks is highlighted in an article in the journal Nature.
Quantum technology based on light (photons) is called quantum photonics, while electronics is based on electrons. Photons (light particles) and electrons behave differently at the quantum level. A quantum entity is the smallest unit in the microscopic world. For example, photons are the fundamental constituent of light and electrons of electric current. Electrons are so-called fermions and can easily be isolated to conduct current one electron at a time. In contrast photons are bosons, which prefer to bunch together. But since information for quantum communication based on photonics is encoded in a single photon, it is necessary to emit and send them one at a time.
The things that can be done with 3D printing never cease to amaze. To the casual observer with only a passing knowledge of the technology, it appears on the surface to be an interesting method of producing plastic odds and ends, and sometimes metal parts – but 3D printing is so much more, as anyone who follows the progression of the technology on a regular basis knows. The things it is capable of producing are often hard to wrap one’s mind around – especially when you look at 3D printing on the nanoscale.
A group of scientists from Lithuania, France and Australia are busy studying 3D printing on a very small scale. As a newly published paper entitled “Optically Clear and Resilient Free-Form μ-Optics 3D-Printed via Ultrafast Laser Lithography” explains, 3D printing is capable of creating functional objects that are impossible to produce via conventional manufacturing techniques, and structures at the miniature, micro- and nanoscales are no exception.
Nice. I want one.
A revamped and rebranded NanoFabrication Kingston has launched with the goal of increasing activity outside of Queen’s University.
“We want to be open to the eastern Ontario community, industry and government as well as academia outside of Queen’s to make, characterize and test devices and samples that are small,” said Rob Knobel, Queen’s University professor and a lead researcher at NanoFabrication Kingston.
In Brief:
As the world of medicine is increasingly changed by biology, technology, communications, genetics, and robotics, predicting the outlook of the next few decades of medicine becomes harder. But that is exactly what Melanie Walker of the World Economic Forum does, and she predicts a bright new future for healthcare.
