Nice read.

The results demonstrate that the positions of tens of thousands of atoms can be precisely identified and then fed into quantum mechanics calculations to correlate imperfections and defects with material properties at the single-atom level. This research will be published Feb 2. in the journal Nature.

Jianwei (John) Miao, a UCLA professor of physics and astronomy and a member of UCLA’s California NanoSystems Institute, led the international team in mapping the atomic-level details of the bimetallic nanoparticle, more than a trillion of which could fit within a grain of sand.

Watch out for the black holes in those QC chips.

Eindhoven professor Rembert Duine has proposed a way to simulate black holes on an electronic chip. This makes it possible to study fundamental aspects of black holes in a laboratory on earth. Additionally, the underlying research may be useful for quantum technologies. Duine (also working at Utrecht University) and colleagues from Chile published their results today in Physical Review Letters.

“Right now, it’s purely theoretical,” says Duine, “but all the ingredients already exist. This could be happening in a lab one or two years from now.” One possibility is in the group of Physics of Nanostructures in the Department of Applied Physics. According to Duine, in these labs experiments are being done that are necessary to create this type of black holes.

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.

A team of scientists engineered a nanoparticle to help remove the toxins found in a wide variety of snake bites. This could impact the estimated 4.5 million people who are bitten by snakes each year, and the 100,000 who die from the venom.

The speed with which microbes in a simplified ecosystem absorb the nanomaterials is raising concerns about the effect on organisms higher in the food chain.
