Process for Regenerating Neurons in the Eye and Brain Identified

Posted by in categories: biotech/medical, neuroscience

Summary: Researchers have identified a network of genes in Zebrafish that regulate the process of determining whether certain neurons will regenerate.

The death of neurons, whether in the brain or the eye, can result in a number of human neurodegenerative disorders, from blindness to Parkinson’s disease. Current treatments for these disorders can only slow the progression of the illness, because once a neuron dies, it cannot be replaced.

Genetic Factor Discovery Enables Adult Skin to Regenerate Like a Newborn Baby’s

Posted by in categories: biotech/medical, genetics, life extension

A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn babe. The discovery by Washington State University researchers has implications for better skin wound treatment as well as preventing some of the aging process in skin.

In a study, published in the journal eLife on September 29, 2020, the researchers identified a factor that acts like a molecular switch in the skin of baby mice that controls the formation of hair follicles as they develop during the first week of life. The switch is mostly turned off after skin forms and remains off in adult tissue. When it was activated in specialized cells in adult mice, their skin was able to heal wounds without scarring. The reformed skin even included fur and could make goosebumps, an ability that is lost in adult human scars.

“We were able to take the innate ability of young, neonatal skin to regenerate and transfer that ability to old skin,” said Ryan Driskell, an assistant professor in WSU’s School of Molecular Biosciences. “We have shown in principle that this kind of regeneration is possible.”

Self-healing, self-monitoring chip rearranges circuit if damaged

Posted by in category: computing

Circa 2013

A standard computer is a complex group of individual parts working together as a whole — RAM, some kind of data storage, a processor, and so on. When one of those integral parts breaks, the computer is rendered useless and the part must be replaced, but what if the computer could begin routing the broken part’s tasks through the parts that are still functional? Computers can’t do that just yet, but researchers have now managed to coax a microchip into doing so.

Verified quantum information scrambling

Posted by in categories: computing, quantum physics

Circa 2019

Quantum scrambling is the dispersal of local information into many-body quantum entanglements and correlations distributed throughout an entire system. This concept accompanies the dynamics of thermalization in closed quantum systems, and has recently emerged as a powerful tool for characterizing chaos in black holes1,2,3,4. However, the direct experimental measurement of quantum scrambling is difficult, owing to the exponential complexity of ergodic many-body entangled states. One way to characterize quantum scrambling is to measure an out-of-time-ordered correlation function (OTOC); however, because scrambling leads to their decay, OTOCs do not generally discriminate between quantum scrambling and ordinary decoherence. Here we implement a quantum circuit that provides a positive test for the scrambling features of a given unitary process5,6. This approach conditionally teleports a quantum state through the circuit, providing an unambiguous test for whether scrambling has occurred, while simultaneously measuring an OTOC. We engineer quantum scrambling processes through a tunable three-qubit unitary operation as part of a seven-qubit circuit on an ion trap quantum computer. Measured teleportation fidelities are typically about 80 per cent, and enable us to experimentally bound the scrambling-induced decay of the corresponding OTOC measurement.

Tesla reportedly eliminates its PR department

Posted by in categories: sustainability, transportation

Tesla apparently has a new strategy for dealing with journalists: Don’t deal with them at all.

The electric car giant has dissolved its global public relations team, leaving the press with no formal point of contact at the world’s most valuable automaker, a new report says.

Essentially every staffer who used to work in Tesla’s PR office has either moved to a different position at the company or left altogether, according to electric vehicle industry blog Electrek, which said the move to disband the department was confirmed “at the highest level at Tesla.”

Researchers crack quantum physics puzzle

Posted by in categories: particle physics, quantum physics

Scientists have re-investigated a sixty-year-old idea by an American physicist and provided new insights into the quantum world.

The research, which took seven years to complete, could lead to improved , laser techniques, interferometric high-precision measurements and atomic beam applications.

Quantum physics is the study of everything around us at the atomic level, , electrons and particles. Atoms and electrons which are so small, one billion placed side by side could fit within a centimeter. Because of the way atoms and electrons behave, scientists describe their behavior as like waves.
