Engineers light the way to nerve-operated prosthetics of the future

Posted by in categories: biotech/medical, cyborgs, neuroscience

Biomedical and electrical engineers at UNSW Sydney have developed a new way to measure neural activity using light—rather than electricity—which could lead to a complete reimagining of medical technologies like nerve-operated prosthetics and brain-machine interfaces.

Professor François Ladouceur, with UNSW’s School of Electrical Engineering and Telecommunications, says the multi-disciplinary team has just demonstrated in the lab what it proved theoretically shortly before the pandemic: that sensors built using liquid crystal and integrated optics technologies—dubbed “optrodes”—can register nerve impulses in a living animal body.

Not only do these optrodes perform just as well as conventional electrodes—that use electricity to detect a nerve impulse—but they also address “very thorny issues that competing technologies cannot address,” says Prof. Ladouceur.

Novel thermal phases of topological quantum matter in the lab

Posted by in categories: computing, particle physics, quantum physics

For the first time, a group of researchers from Universidad Complutense de Madrid, IBM, ETH Zurich, MIT and Harvard University have observed topological phases of matter of quantum states under the action of temperature or certain types of experimental imperfections. The experiment was conducted using quantum simulator at IBM.

Quantum simulators were first conjectured by the Nobel Prize laureate Richard Feynman in 1982. Ordinary classical computers are inefficient at simulating systems of interacting quantum particles These new simulators are genuinely quantum and can be controlled very precisely. They replicate other quantum systems that are harder to manipulate and whose physical properties remain very much unknown.

In an article published in the journal Quantum Information, the researchers describe using a with superconducting qubits at IBM to replicate materials known as topological insulators at finite temperature, and measure for the first time their topological quantum phases.

Breakthrough in CRISPR research may lead to more effective and safer gene editing

Posted by in categories: bioengineering, biotech/medical

10 years ago we saw a breakthrough in modern biology.

An American scientist discovered that manipulation of the Cas9 protein resulted in a gene technology worthy of a sci-fi film: CRISPR.

Think of it as a pair of molecular scissors capable of cutting and editing the DNA of humans, animals, plants, bacteria and viruses.

Dissociable rhythmic mechanisms enhance memory for conscious and nonconscious perceptual contents

Posted by in category: neuroscience

Understanding the neural mechanisms of conscious and unconscious experience is a major goal of fundamental and translational neuroscience. Here, we target the early visual cortex with a protocol of noninvasive, high-resolution alternating current stimulation while participants performed a delayed target–probe discrimination task and reveal dissociable mechanisms of mnemonic processing for conscious and unconscious perceptual contents. Entraining β-rhythms in bilateral visual areas preferentially enhanced short-term memory for seen information, whereas α-entrainment in the same region preferentially enhanced short-term memory for unseen information. The short-term memory improvements were frequency-specific and long-lasting. The results add a mechanistic foundation to existing theories of consciousness, call for revisions to these theories, and contribute to the development of nonpharmacological therapeutics for improving visual cortical processing.

Creepy AI predicts face of ‘last human on Earth’ and the results are eerie

Posted by in category: robotics/AI

ARTIFICIAL intelligence has predicted what “the last human on Earth” will look like.

The U.S. Sun asked DALL·E, an artificially intelligent software, to make the prediction and it came up with some rather creepy results.

DALL·E is a machine learning model that was created by OpenAI to conjure up unusual images from keyword prompts.

Hawaii Officials Warn World’s Largest Active Volcano Could Erupt

Posted by in category: futurism

The volcano has been in a state of “heightened unrest” for more than a month, with the number of earthquakes rising from between 10 and 20 per day to 40 to 50 per day, likely due to an increase in magma inside the volcano, according to the Hawaiian Volcano Observatory.

The strongest was a 5.0-magnitude earthquake that struck the Big Island two weeks ago, although local officials said it did not cause major damage or injuries.

Give peace a chance in Ukraine: The chorus rises, around the world and across the spectrum

Posted by in categories: ethics, existential risks, military

The escalating crisis exposes the weakness of Biden’s position. He is gambling with hundreds of thousands of Ukrainian lives, over which he has no moral claim, that Ukraine will somehow be in a stronger military position after a winter of war and power outages, with hundreds of thousands more Russian troops in the areas they control. This is a bet on a much longer war, in which U.S. taxpayers will shell out for thousands of tons of weapons and many more Ukrainians will die, with no clear endgame short of nuclear war.

#StopWar #NoWar #NuclearWar #WW3


Leaders in the global South, former U.S. diplomats and Henry Kissinger (!) agree: It’s time to negotiate for real.
