University of Arizona aerospace and mining engineers are mapping out a plan for harvesting the moon’s resources using autonomous robot swarms and new excavation techniques.

With scientists beginning to more seriously consider constructing bases on celestial bodies such as the moon, the idea of space mining is growing in popularity.

After all, if someone from Los Angeles was moving to New York to build a house, it would be a lot easier to buy the building materials in New York rather than buy them in Los Angeles and lug them 2,800 miles. Considering the distance between Earth and the moon is about 85 times greater, and that getting there requires defying gravity, using the moon’s existing resources is an appealing idea.

Summary: Researchers find a region of the brain stem called the periaqueductal gray may mediate religiosity and spirituality in humans.

Source: Elsevier.

Scientists have long suspected that religiosity and spirituality could be mapped to specific brain circuits, but the location of those circuits remains unknown. Now, a new study using novel technology and the human connectome, a map of neural connections, has identified a brain circuit that seems to mediate that aspect of our personality.

Qualcomm has unveiled the world’s first drone platform and reference design that will tap in both 5G and AI technologies. The chipmaker’s Flight RB5 5G Platform condenses multiple complex technologies into one tightly integrated drone system to support a variety of use cases, including film and entertainment, security and emergency response, delivery, defense, inspection, and mapping.

The Flight RB5 5G Platform is powered by the chipmaker’s QRB5165 processor and builds upon the company’s latest IoT offerings to offer high-performance and heterogeneous computing at ultra-low power consumption.

When SpaceX deploy batches of Starlink satellites they drop them off in lower orbits and expect the satellites themselves to navigate towards their final operational orbits. This is quite a complex process and one that’s worth discussing, the satellites need to be able to reach the target orbital plane, raise the orbit to operational altitude, and then finally maneuver to a specific slot within that plane before they become operational.

A new tool helps researchers explore the types of cells that make up brain organoids — clusters of cells that can mimic the basic structure, function and development of different parts of the brain.

The software, detailed in Cell Stem Cell, maps information about when and where genes are expressed in brain organoids onto a reference atlas of the developing mouse brain. Scientists can use the resulting overlay to develop organoids that better recapitulate the developing brain, the team says, or to uncover the effects of gene mutations and other experimental perturbations.

Brain organoids derived from the cells of people with conditions such as autism have proved useful in capturing neuronal abnormalities. But the findings are muddied by methodological differences in how researchers develop these lab-grown blobs. Advanced techniques to profile gene expression in single cells have made it easier to identify the cell types in any given organoid. But it’s remained difficult to map those cell types onto different brain regions.

Starting September 27th.

If you still have a device running Android 2.3.7 (the final version of Gingerbread) or older, Google won’t let you sign in to your Google account on that device starting September 27th, according to a support document (via Liliputing).

“As part of our ongoing efforts to keep our users safe, Google will no longer allow sign-in on Android devices that run Android 2.3.7 or lower starting September 27, 2021,” the company says. “If you sign into your device after September 27, you may get username or password errors when you try to use Google products and services like Gmail, YouTube, and Maps.”

The tool next examines how one protein’s amino acids interact with another within the same protein, for example, by examining the distance between two distant building blocks. It’s like looking at your hands and feet fully stretched out, versus in a backbend measuring the distance between those extremities as you “fold” into a yoga pose.

Finally, the third track looks at 3D coordinates of each atom that makes up a protein building block—kind of like mapping the studs on a Lego block—to compile the final 3D structure. The network then bounces back and forth between these tracks, so that one output can update another track.

The end results came close to those of DeepMind’s tool, AlphaFold2, which matched the gold standard of structures obtained from experiments. Although RoseTTAFold wasn’t as accurate as AlphaFold2, it seemingly required much less time and energy. For a simple protein, the algorithm was able to solve the structure using a gaming computer in about 10 minutes.
