"""
At least two research teams are engineering stem cells to include Neanderthal genes and growing them into "minibrains"
[...]
Muotri focused on one of approximately 200 protein-coding genes that differ between Neanderthals and modern humans. Known as NOVA1, it plays a role in early brain development in modern humans and also is linked to autism and schizophrenia. Because it controls splicing of RNA from other genes, it likely helped produce more than 100 novel brain proteins in Neanderthals. Conveniently, just one DNA base pair differs between the Neanderthal gene and the modern human one.
[...]
Muotri has developed the modern human brain organoids to the stage where his team can detect oscillating electrical signals within the balls of tissue. They are now wiring the organoids to robots that resemble crabs, hoping the organoids will learn to control the robots' movements. Ultimately, Muotri wants to pit them against robots run by brain Neanderoids.

Motion tracking

As your phone moves through the world, ARCore uses a process called concurrent odometry and mapping, or COM, to understand where the phone is relative to the world around it. ARCore detects visually distinct features in the captured camera image called feature points and uses these points to compute its change in location. The visual information is combined with inertial measurements from the device's IMU to estimate the pose (position and orientation) of the camera relative to the world over time.

By aligning the pose of the virtual camera that renders your 3D content with the pose of the device's camera provided by ARCore, developers are able to render virtual content from the correct perspective. The rendered virtual image can be overlayed on top of the image obtained from the device's camera, making it appear as if the virtual content is part of the real world.

Environmental understanding

ARCore is constantly improving its understanding of the real world environment by detecting feature points and planes.

ARCore looks for clusters of feature points that appear to lie on common horizontal or vertical surfaces, like tables or walls, and makes these surfaces available to your app as planes. ARCore can also determine each plane's boundary and make that information available to your app. You can use this information to place virtual objects resting on flat surfaces.

Because ARCore uses feature points to detect planes, flat surfaces without texture, such as a white wall, may not be detected properly.

Light estimation

ARCore can detect information about the lighting of its environment and provide you with the average intensity and color correction of a given camera image. This information lets you light your virtual objects under the same conditions as the environment around them, increasing the sense of realism.

the optional the “SpaceX package” will replace the mysterious back seats [...] COPV containing ultra high-pressure air that can be released for thrust. The air is going to be automatically added by air pumps using power from the Roadster’s battery pack [...] as many as 10 of those systems all around the vehicle, which would help not only for speed and acceleration but also for deceleration and possibly even to turn.
