Researchers at the Center for Quantum Nanoscience (QNS) within the Institute for Basic Science (IBS) achieved a major breakthrough in shielding the quantum properties of single atoms on a surface. The scientists used the magnetism of single atoms, known as spin, as a basic building block for quantum information processing. The researchers could show that by packing two atoms closely together they could protect their fragile quantum properties much better than for just one atom.

The spin is a fundamental quantum mechanical object and governs magnetic properties of materials. In a classical picture, the spin often can be considered like the needle of a compass. The north or south poles of the needle, for example, can represent spin up or down. However, according to the laws of quantum mechanics, the spin can also point in both directions at the same time. This superposition state is very fragile since the interaction of the spin with the local environment causes dephasing of the superposition. Understanding the dephasing mechanism and enhancing the quantum coherence are one of the key ingredients toward spin-based quantum information processing.

In this study, published in the journal Science Advances in November 9, 2018, QNS scientists tried to suppress the decoherence of single atoms by assembling them closely together. The spins, for which they used single titanium atoms, were studied by using a sharp metal tip of a scanning tunneling microscope and the atoms’ spin states were detected using electron spin resonance. The researchers found that by bringing the atoms very close together (1 million times closer than a millimeter), they could protect the superposition states of these two magnetically coupled atoms 20 times longer compared to an individual atom.

It simply twists its way through the dense tissue.

Rutgers scientists have created a tiny, biodegradable scaffold to transplant stem cells and deliver drugs, which may help treat Alzheimer’s and Parkinson’s diseases, aging brain degeneration, spinal cord injuries and traumatic brain injuries.

Stem cell transplantation, which shows promise as a treatment for central nervous system diseases, has been hampered by low cell survival rates, incomplete differentiation of cells and limited growth of neural connections.

So, Rutgers scientists designed bio-scaffolds that mimic natural tissue and got good results in test tubes and mice, according to a study in Nature Communications. These nano-size scaffolds hold promise for advanced stem cell transplantation and neural tissue engineering. Stem cell therapy leads to stem cells becoming neurons and can restore neural circuits.

The new method uses a red glow to screen hundreds of nanoparticles at once to find which could best deliver drugs into living cells.

In the spirit of Halloween, where ghouls, ghosts, and vampires walk among us, our perception of reality will soon transform as well, forever possessed by the specter of Transhumanism!

Last year, I wrote about how people could transform themselves into one of my favorite horror creatures—a real-life werewolf—using modern science and tech. This merely scratches the surface, however, in terms of how far an individual can go. In a Transhumanist future, you’ll be empowered to not only question the extent of your humanity but equally put those questions into action.

Scientists say just 1 cubic centimetre of the carbon nanotube material won’t break under the weight of more than 800 tonnesTsinghua University researchers are trying to get the fibre into mass production for use in military or other areas.

“Previous work mostly focused on what was going on at the microscale of DNA,” says study co-author Michael Shelley, group leader for biophysical modeling at the Flatiron Institute’s Center for Computational Biology in New York City and co-director of the Courant Institute’s Applied Mathematics Laboratory at New York University. “People didn’t really think about what was going on at the larger scale.”

Shelley and colleagues simulated the motions of chromatin, the functional form of DNA inside the nucleus. Chromatin looks like beads on a string, with ball-like clusters of genetic material linked by strands of DNA. The researchers propose that molecular machines along the DNA cause segments of the chromatin to straighten and pull taut. This activity aligns neighboring strands to face the same direction. That alignment, in turn, results in a cascading waltz of genetic material shimmying across the nucleus.

The dancing DNA may play a role in gene expression, replication and remodeling, though the exact effects remain unclear, the researchers reported online October 22 in Proceedings of the National Academy of Sciences.
