How Left and Right Hippocampal CA1 Regions in the Mouse Brain Talk With Each Other
Researchers have uncovered neural circuitry that allows the CA1 region of th… See more.
Summary: Researchers have uncovered neural circuitry that allows the CA1 region of the hippocampus to communicate with its counterpart in the opposite hemisphere despite there being no connection between them.

RIKEN neuroscientists have uncovered the neural circuitry that permits a subregion in the hippocampus to communicate with its counterpart in the opposite hemisphere despite there being no direct connection between them. While not directly applicable to people, this finding is important for informing future studies of the mouse brain.
The hippocampus is well known for its role in learning and memory. Vertebrates have two hippocampi: one on the left side of the brain and the other on the right. Each hippocampus has various subregions, including the CA1 and CA3 areas.
Automated reasoning’s scientific frontiers

Distributing proof search, reasoning about distributed systems, and automating regulatory compliance are just three fruitful research areas.
Apple’s Steve Wozniak to 3D Print Satellite Chassis with Desktop Metal’s Titanium
Titanium is the lifeblood of metal 3D printing. As the technology was initially driven by the aerospace and weapons sectors, it has become the metal of choice for its high strength-to-weight ratio. Now, Desktop Metal (NYSE: DM) has qualified titanium alloy Ti-6Al-4V (Ti64) for its Studio Systems 2, making it one of the first office-friendly machines capable of 3D printing with titanium. One of Desktop Metal’s first customers in the space appears to be Apple co-founder Steve Wozniak, whose new startup, Privateer Space, aims to clean up space junk.

YouTuber and scientist Derek Muller offers a look at Relativity Space, an aerospace company 3D printing orbital rocket parts, in a new video.
Mega Comet Arriving From the Oort Cloud Is 85 Miles Wide
Oort Cloud comet C/2014 UN271, also known as Comet measures some 85 miles (137 km) in diameter, give or take 10.5 miles (17 km), reports a research team led by astronomer Emmanuel Lellouch of the Paris Observatory. Their new paper on the mega comet has been accepted for publication in Astronomy and Astrophysics Letters, and you can sneak a peak of the preprint at the arXiv.
These latest observations confirm that Comet is the largest Oort Cloud object ever detected, as it’s nearly twice as big as comet Hale-Bopp (observed in 1997), the nucleus of which measured between 25 and 50 miles (40 and 80 km) wide. It’s also bigger than Comet Sarabat (observed in 1729), which had a nucleus measuring somewhere around 62 miles (100 km) in diameter.
Comet is currently inbound from the Oort Cloud 0, a distant region of the solar system known for packing billions and possibly trillions of icy objects. The comet will make its closest approach to Earth in 2031, when it will come to within 11 au of the Sun (1 billion miles), in which 1 au is the average distance from Earth to the Sun. The comet, coming no closer than Saturn, won’t likely be visible to the unaided eye, but astronomers will be keeping a close watch, as it’s turning out to be a rather extraordinary object.
