Neura Pod is a series covering topics related to Neuralink, Inc. Topics such as brain-machine interfaces, brain injuries, and artificial intelligence will be explored. Host Ryan Tanaka synthesizes informationopinions, and conducts interviews to easily learn about Neuralink and its future.

Most people aren’t aware of what the company does, or how it does it. If you know other people who are curious about what Neuralink is doing, this is a nice summary episode to share. Tesla, SpaceX, and the Boring Company are going to have to get used to their newest sibling. Neuralink is going to change how humans think, act, learn, and share information.

Quasars, X-ray Binaries and Supermassive voids at the center of our galaxies … black holes take many forms. In this episode Matt tells us what these different types of black holes are and how scientists are using VLBI, Very Long Baseline Interferometry, to map the different black holes throughout the known universe.

Why Microsoft may beat Zuckerberg to the metaverse

When comparing Meta — formerly Facebook — and Microsoft’s approaches to the metaverse, it’s clear Microsoft has a much more grounded and realistic vision. Although Meta currently leads in the provision of virtual reality (VR) devices (through its ownership of what was previously called Oculus), Microsoft is adapting technologies that are currently more widely used. The small, steady steps Microsoft is making today put it in a better position to be one of the metaverse’s future leaders. However, such a position comes with responsibilities, and Microsoft needs to be prepared to face them.

The metaverse is a virtual world where users can share experiences and interact in real-time within simulated scenarios. To be clear, no one knows yet what it will end up looking like, what hardware it will use, or which companies will be the main players — these are still early days. However, what is certain is that VR will play a key enabling role; VR-related technologies such as simultaneous location and mapping (SLAM), facial recognition, and motion tracking will be vital for developing metaverse-based use cases.

NASA Once Again Chooses SpaceX For New Mission GOES-U

NASA Once Again Chooses SpaceX For New Mission GOES-U: GOES-U will provide advanced imagery and atmospheric measurements of Earth’s weather, oceans, and environment, as well as real–time mapping of total lightning activity and improved monitoring of solar activity and space weather.

These satellites will be used by NOAA to forecast potentially hazardous weather and regularly monitor the weather. The weather of a particular region can be seen through the GOES-R series of satellites.

On the website, it says, “The GOES-R Series provides advanced imagery and atmospheric measurements of Earth’s weather, oceans and environment, real-time mapping of total lightning activity, and improved monitoring of solar activity and space weather.”

Google Maps of the Cosmos is now in the development stage

The comprehensive maps of the entire observable Universe is now in development.

A Co-founder of Apple has reported that his new organization is moving towards the objective of building the ‘Google maps of space’.

It wasn’t too quite a while in the past that a prime supporter of Apple declared he was joining the private space industry with an organization called Privateer.

That Apple prime supporter is in all honesty Steve Wozniak, and part of the way through September, Wozniak declared Privateer Space, a space-based organization that is reason remains covered in secret. What we do think about Privateer Space is that it anticipates handling the steadily developing issue of room garbage, however, how the organization will tackle this issue is obscure.

Extreme Geophysics: Quantum Phase Transition Detected on a Global Scale Deep Inside the Earth

Multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth’s mantle.

The interior of the Earth is a mystery, especially at greater depths (660 km). Researchers only have seismic tomographic images of this region and, to interpret them, they need to calculate seismic (acoustic) velocities in minerals at high pressures and temperatures. With those calculations, they can create 3D velocity maps and figure out the mineralogy and temperature of the observed regions. When a phase transition occurs in a mineral, such as a crystal structure change under pressure, scientists observe a velocity change, usually a sharp seismic velocity discontinuity.

In 2,003 scientists observed in a lab a novel type of phase change in minerals — a spin change in iron in ferropericlase, the second most abundant component of the Earth’s lower mantle. A spin change, or spin crossover, can happen in minerals like ferropericlase under an external stimulus, such as pressure or temperature. Over the next few years, experimental and theoretical groups confirmed this phase change in both ferropericlase and bridgmanite, the most abundant phase of the lower mantle. But no one was quite sure why or where this was happening.

Deep learning helps predict traffic crashes before they happen

Today’s world is one big maze, connected by layers of concrete and asphalt that afford us the luxury of navigation by vehicle. For many of our road-related advancements — GPS lets us fire fewer neurons thanks to map apps, cameras alert us to potentially costly scrapes and scratches, and electric autonomous cars have lower fuel costs — our safety measures haven’t quite caught up. We still rely on a steady diet of traffic signals, trust, and the steel surrounding us to safely get from point A to point B.

“If people can use the risk map to identify potentially high-risk road segments, they can take action in advance to reduce the risk of trips they take. Apps like Waze and Apple Maps have incident feature tools, but we’re trying to get ahead of the crashes — before they happen,” says He.

A deep model was trained on historical crash data, road maps, satellite imagery, and GPS to enable high-resolution crash maps that could lead to safer roads.

But no one was quite sure why or where this was happening.

In 2,006 Columbia Engineering Professor Renata Wentzcovitch published her first paper on ferropericlase, providing a theory for the spin crossover in this mineral. Her theory suggested it happened across a thousand kilometers in the lower mantle. Since then, Wentzcovitch, who is a professor in the and applied mathematics department, earth and environmental sciences, and Lamont-Doherty Earth Observatory at Columbia University, has published 13 papers with her group on this topic, investigating velocities in every possible situation of the spin crossover in ferropericlase and bridgmanite, and predicting properties of these minerals throughout this crossover. In 2,014 Wenzcovitch, whose research focuses on computational quantum mechanical studies of materials at extreme conditions, in particular planetary materials predicted how this spin change phenomenon could be detected in seismic tomographic images, but seismologists still could not see it.
