The Unconventional Computing Laboratory (UCL) from the University of the West of England (UWE Bristol) has showcased its mushroom motherboard to Popular Science (opens in new tab). As its name conveys, the lab, led by professor Andrew Adamatzk, focuses on eccentric approaches to computing, like wetware, the notion of applying the concepts of hardware and software to living creatures.

Fungi connect to a root network under the ground (sometimes called the “wood wide web”) using their mycelium, very slim hyphae that are the size of a thread. The fungal motherboard utilizes the mycelium as a conductor and a substitute for other electronic components, such as the processor or memory. In a previous study (opens in new tab), Adamatzky demonstrated that mushrooms could communicate with each through electric signals via the mycelium. The mycelium is capable of sending and receiving electrical signals and retaining memory.

Scientists are vigorously competing to transform the counterintuitive discoveries about the quantum realm from a century past into technologies of the future. The building block in these technologies is the quantum bit, or qubit. Several different kinds are under development, including ones that use defects within the symmetrical structures of diamond and silicon. They may one day transform computing, accelerate drug discovery, generate unhackable networks and more.

Working with researchers from several universities, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have discovered a method for introducing spinning electrons as qubits in a host nanomaterial. Their test results revealed record long coherence times—the key property for any practical qubit because it defines the number of quantum operations that can be performed in the lifetime of the qubit.

Electrons have a property analogous to the spin of a top, with a key difference. When tops spin in place, they can rotate to the right or left. Electrons can behave as though they were rotating in both directions at the same time. This is a quantum feature called superposition. Being in two states at the same time makes electrons good candidates for spin qubits.

There’s an excessive amount of innovation embedded in right now’s cutting-edge pc chips, however not a lot of it’s as out-of-the-box because the considering that’s driving Australian startup Cortical Labs. The corporate, like so many startups with synthetic intelligence in thoughts, is constructing pc chips that borrow their neural community inspiration from the organic mind. The distinction? Cortical is utilizing precise organic neurons, taken from mice and people, to make their chips.

“We’re constructing the primary hybrid pc chip which entails implanting organic neurons on silicon chips,” Hon Weng Chong, CEO and co-founder of Cortical Labs, informed Digital Tendencies.

That is completed by first extracting neurons in two other ways, both from a mouse embryo or by remodeling human pores and skin cells again into stem cells and inducing these to develop into human neurons.

To ensure your survival, your brain evolved to avoid one thing: uncertainty. As neuroscientist Beau Lotto points out, if your ancestors wondered for too long whether that noise was a predator or not, you wouldn’t be here right now. Our brains are geared to make fast assumptions, and questioning them in many cases quite literally equates to death. No wonder we’re so hardwired for confirmation bias. No wonder we’d rather stick to the status quo than risk the uncertainty of a better political model, a fairer financial system, or a healthier relationship pattern. But here’s the catch: as our brains evolved toward certainty, we simultaneously evolved away from creativity—that’s no coincidence; creativity starts with a question, with uncertainty, not with a cut and dried answer. To be creative, we have to unlearn millions of years of evolution. Creativity asks us to do that which is hardest: to question our assumptions, to doubt what we believe to be true. That is the only way to see differently. And if you think creativity is a chaotic and wild force, think again, says Beau Lotto. It just looks that way from the outside. The brain cannot make great leaps, it can only move linearly through mental possibilities. When a creative person forges a connection between two things that are, to your mind, so far apart, that’s a case of high-level logic. They have moved through steps that are invisible to you, perhaps because they are more open-minded and well-practiced in questioning their assumptions. Creativity, it seems, is another (highly sophisticated) form of logic. Beau Lotto is the author of Deviate: The Science of Seeing Differently.

Year 2022 face_with_colon_three

For more than 250 years, mathematicians have wondered if the Euler equations might sometimes fail to describe a fluid’s flow. A new computer-assisted proof marks a major breakthrough in that quest.

According to reports from Spanish newspaper El País, researchers have discovered a way to speed up, slow down, and even reverse quantum time by taking advantage of unusual properties within a quantum world in specific ways. It’s a huge breakthrough, which the researchers have detailed in a series of six new papers featured in Advancing Physics.

The papers were originally published in 2018, and they detail how researchers were able to rewind time to a previous scene, as well as even skip several scenes forward. Being able to reverse and even control quantum time is a huge step forward, especially as we’ve seen increasing movements into quantum simulators.

The realm of quantum physics is a complex one, no doubt, and with analog quantum computers showing such promise at solving intense problems, it only seens fitting that research into controlling and reversing quantum time would prove so fruitful. The researchers say that the control they can acquire on the quantum world is very similar to controlling a movie.

In 2022, Elon Musk’s Neuralink tried – and failed – to secure permission from the FDA to run a human trial of its implantable brain-computer interface (BCI), according to a Reuters report published Thursday.

Citing seven current and former employees, speaking on the condition of anonymity, Reuters reported that the regulatory agency found “dozens of issues” with Neuralink’s application that the company must resolve before it can begin studying its tech in humans.

In work that could lead to important new physics with potentially heady applications in computer science and more, MIT scientists have shown that two previously separate fields in condensed matter physics can be combined to yield new, exotic phenomena.

The work is theoretical, but the researchers are excited about collaborating with experimentalists to realize the predicted phenomena. The team includes the conditions necessary to achieve that ultimate goal in a paper published in the February 24 issue of Science Advances.

“This work started out as a theoretical speculation, and ended better than we could have hoped,” says Liang Fu, a professor in MIT’s Department of Physics and leader of the work. Fu is also affiliated with the Materials Research Laboratory. His colleagues are Nisarga Paul, a physics graduate student, and Yang Zhang, a postdoctoral associate who is now a professor at the University of Tennessee.
