Neuralink Admits That Implant’s Threads Have Retracted From First Patient’s Brain, Possibly Due to Air in Skull
Not ideal!
In January, multi-hyphenate billionaire Elon Musk announced that his brain-computer interface startup Neuralink had successfully implanted a wireless brain chip into a human subject for the first time.
Over the next couple of months, 29-year-old Noland Arbaugh was shown moving a cursor with his mind, playing Civilization VI and even a fast-paced round of Mario Kart.
But as the Wall Street Journal reports, there have been complications behind the scenes. After it reached out to Neuralink, the company conceded in a blog post that there have been issues with the implant.
Ten years of neuroscience at Google yields maps of human brain
Reconstruction of 1 mm3 of human brain (at 1.4 petabytes of EM data) published by @stardazed0 (@GoogleAI) & Lichtman lab.

Marking ten years of connectomics research at Google, we are releasing a publication in Science about a reconstruction at the synaptic level of a small piece of the human brain. We discuss the reconstruction process and dataset, and we present several new neuron structures discovered in the data.
‘Superfluid spacetime’ points to unification of physics
Since superfluid light exists in computers I think frankly we may already solve the theory of everything because the missing piece is infinity in all things which solves all future problems.
Thinking of spacetime as a liquid may be a helpful analogy. We often picture space and time as fundamental backdrops to the universe. But what if they are not fundamental, and built instead of smaller ingredients that exist on a deeper layer of reality that we cannot sense? If that were the case, spacetime’s properties would “emerge” from the underlying physics of its constituents, just as water’s properties emerge from the particles that comprise it. “Water is made of discrete, individual molecules, which interact with each other according to the laws of quantum mechanics, but liquid water appears continuous and flowing and transparent and refracting,” explains Ted Jacobson, a physicist at the University of Maryland, College Park. “These are all ‘emergent’ properties that cannot be found in the individual molecules, even though they ultimately derive from the properties of those molecules.”
Physicists have been considering this possibility since the 1990s in an attempt to reconcile the dominant theory of gravity on a large scale — general relativity — with the theory governing the very smallest bits of the universe—quantum mechanics. Both theories appear to work perfectly within their respective domains, but conflict with one another in situations that combine the large and small, such as black holes (extremely large mass, extremely small volume). Many physicists have tried to solve the problem by ‘quantizing’ gravity — dividing it into smaller bits, just as quantum mechanics breaks down many quantities, such as particles’ energy levels, into discrete packets. “There are many attempts to quantize gravity—string theory and loop quantum gravity are alternative approaches that can both claim to have gone a good leg forward,” says Stefano Liberati, a physicist at the International School for Advanced Studies (SISSA) in Trieste, Italy.
Neuralink’s First Brain Implant Patient Now Beats Friends in Video Games
Neuralink’s first human patient has become so adept at using the company’s brain implant that he can now beat other players at video games.
On Wednesday, Elon Musk’s company provided a progress update on Noland Arbaugh, who received a brain implant in January that lets him remotely control the cursor on a laptop.
In March, Neuralink revealed that Arbaugh was using the implant to play games including Chess, Civilization VI, and Mario Kart. In Wednesday’s update, the company reported that Arbaugh’s use of the implant has only improved over time.
How Schrödinger’s cat could make quantum computers work better
A quantum bit inspired by Schrödinger’s cat can resist making errors for an unprecedentedly long time, which makes it a candidate for building less error-prone quantum computers.
Quantum computers are revealing an unexpected new theory of reality
A powerful new idea about how the laws of physics work could bring breakthroughs on everything from quantum gravity to consciousness, says researcher Chiara Marletto
Physicists Develop Groundbreaking Device for Advanced Quantum Computing
Researchers have made a significant advancement in quantum computing by adapting a microwave circulator to precisely control the nonreciprocity between a qubit and a resonant cavity. This innovation not only enhances the control within quantum computers but also simplifies the theoretical models for future research.
Scientists led by the University of Massachusetts Amherst have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity between a qubit, the fundamental unit of quantum computing, and a microwave-resonant cavity. The ability to precisely tune the degree of nonreciprocity is an important tool to have in quantum information processing.
In doing so, the team, including collaborators from the University of Chicago, derived a general and widely applicable theory that simplifies and expands upon older understandings of nonreciprocity so that future work on similar topics can take advantage of the team’s model, even when using different components and platforms. The research was published recently in Science Advances.
Physicist achieve milestone in quantum simulation with circular Rydberg qubits
The paper is published in the journal Physical Review X.
In the world of quantum computing and quantum simulation technology, there is a fundamental challenge when using neutral atoms: The lifetime of Rydberg atoms, which are the building blocks for quantum computing, is limited. But there is a promising solution: circular Rydberg states.
For the first time, the research team has succeeded in generating and capturing circular Rydberg atoms of an alkaline-earth metal in an array of optical tweezers.
